For me, most of the time there is not, actually they add overhead IMO
(at least for my purposes) so I actually just build meta-form-wrapper
helpers that generate generic left_text_area and other methods like it
that just add the classes I need for forms and wrap the <section>'s
around the generic helpers that Rails already provides. That is,
instead of including another dependency that I don't need, but for
some people they bring great benefit because they can handle HTML from
step 1 to end, I don't like that because I prefer to directly control
every bit of output my app makes.

Only you can evaluate whether or not they are worth it, it's a battle
of your own to fight, I can honestly say I would use them if I
actually had a use for them, and many people will agree they have a
use for them, but I personally don't have a use for them so I choose
not to use them.  You have to evaluate that for yourself.

Ruby on Rails

Heres a problem I'm running into.


https://github.com/rails/rails/issues/8087

On Monday, October 29, 2012 10:18:04 AM UTC-7, Santiago Pastorino wrote:
Hi everyone,

Rails 3.2.9.rc1 has been released. If no regressions are found I will
release 3.2.9 final this Thursday 1st. If you find a regression open an
issue on github and mention me on it, mail me or tweet me, whatever but
let me know :).

## CHANGES since 3.2.8

*Action Mailer*

* Do not render views when mail() isn't called.
  Fix #7761

  *Yves Senn*


*Action Pack*

*   Accept :remote as symbolic option for `link_to` helper. *Riley Lynch*

*   Warn when the `:locals` option is passed to `assert_template`
outside of a view test case
    Fix #3415

    *Yves Senn*

*   Rename internal variables on ActionController::TemplateAssertions to prevent
    naming collisions. @partials, @templates and @layouts are now
prefixed with an underscore.
    Fix #7459

    *Yves Senn*

*   `resource` and `resources` don't modify the passed options hash
    Fix #7777

    *Yves Senn*

*   Precompiled assets include aliases from foo.js to foo/index.js and
vice versa.

        # Precompiles phone-<digest>.css and aliases phone/index.css
to phone.css.
        config.assets.precompile = [ 'phone.css' ]

        # Precompiles phone/index-<digest>.css and aliases phone.css
to phone/index.css.
        config.assets.precompile = [ 'phone/index.css' ]

        # Both of these work with either precompile thanks to their aliases.
        <%= stylesheet_link_tag 'phone', media: 'all' %>
        <%= stylesheet_link_tag 'phone/index', media: 'all' %>

    *Jeremy Kemper*

*   `assert_template` is no more passing with what ever string that matches
    with the template name.

    Before when we have a template `/layout/hello.html.erb`, `assert_template`
    was passing with any string that matches. This behavior allowed false
    positive like:

        assert_template "layout"
        assert_template "out/hello"

    Now it only passes with:

        assert_template "layout/hello"
        assert_template "hello"

    Fixes #3849.

    *Hugolnx*

*   Handle `ActionDispatch::Http::UploadedFile` like
`Rack::Test::UploadedFile`, don't call to_param on it. Since
    `Rack::Test::UploadedFile` isn't API compatible this is needed to
test file uploads that rely on `tempfile`
    being available.

    *Tim Vandecasteele*

*   Fixed a bug with shorthand routes scoped with the `:module` option not
    adding the module to the controller as described in issue #6497.
    This should now work properly:

        scope :module => "engine" do
          get "api/version" # routes to engine/api#version
        end

    *Luiz Felipe Garcia Pereira*

*   Respect `config.digest = false` for `asset_path`

    Previously, the `asset_path` internals only respected the `:digest`
    option, but ignored the global config setting. This meant that
    `config.digest = false` could not be used in conjunction with
    `config.compile = false` this corrects the behavior.

    *Peter Wagenet*

*   Fix #7646, the log now displays the correct status code when an
exception is raised.

    *Yves Senn*

*   Fix handling of date selects when using both disabled and discard options.
    Fixes #7431.

    *Vasiliy Ermolovich*

*   Fix select_tag when option_tags is nil.
    Fixes #7404.

    *Sandeep Ravichandran*

*   `javascript_include_tag :all` will now not include
`application.js` if the file does not exists. *Prem Sichanugrist*

*   Support cookie jar options (e.g., domain :all) for all session stores.
    Fixes GH#3047, GH#2483.

    *Ravil Bayramgalin*

*   Performance Improvement to send_file: Avoid having to pass an open
file handle as the response body. Rack::Sendfile
    will usually intercept the response and just uses the path
directly, so no reason to open the file. This performance
    improvement also resolves an issue with jRuby encodings, and is
the reason for the backport, see issue #6844.

    *Jeremy Kemper & Erich Menge*


*Active Model*

*   Due to a change in builder, nil values and empty strings now generates
    closed tags, so instead of this:

        <pseudonyms nil=\"true\"></pseudonyms>

    It generates this:

        <pseudonyms nil=\"true\"/>

    *Carlos Antonio da Silva*


*Active Record*

*   Fix bug where `update_columns` and `update_column` would not let
you update the primary key column.

    *Henrik Nyh*

*   Decode URI encoded attributes on database connection URLs.

    *Shawn Veader*

*   Fix AR#dup to nullify the validation errors in the dup'ed object.
Previously the original
    and the dup'ed object shared the same errors.

    * Christian Seiler*

*   Synchronize around deleting from the reserved connections hash.
    Fixes #7955

*   PostgreSQL adapter correctly fetches default values when using
    multiple schemas and domains in a db. Fixes #7914

    *Arturo Pie*

*   Fix deprecation notice when loading a collection association that
    selects columns from other tables, if a new record was previously
    built using that association.

    *Ernie Miller*

*   The postgres adapter now supports tables with capital letters.
    Fix #5920

    *Yves Senn*

*   `CollectionAssociation#count` returns `0` without querying if the
    parent record is not persisted.

    Before:

        person.pets.count
        # SELECT COUNT(*) FROM "pets" WHERE "pets"."person_id" IS NULL
        # => 0

    After:

        person.pets.count
        # fires without sql query
        # => 0

    *Francesco Rodriguez*

*   Fix `reset_counters` crashing on `has_many :through` associations.
    Fix #7822.

    *lulalala*

*   ConnectionPool recognizes checkout_timeout spec key as taking
    precedence over legacy wait_timeout spec key, can be used to avoid
    conflict with mysql2 use of wait_timeout.  Closes #7684.

    *jrochkind*

*   Rename field_changed? to _field_changed? so that users can create
a field named field

    *Akira Matsuda*, backported by *Steve Klabnik*

*   Fix creation of through association models when using `collection=[]`
    on a `has_many :through` association from an unsaved model.
    Fix #7661.

    *Ernie Miller*

*   Explain only normal CRUD sql (select / update / insert / delete).
    Fix problem that explains unexplainable sql. Closes #7544 #6458.

    *kennyj*

*   Backport test coverage to ensure that PostgreSQL auto-reconnect
functionality
    remains healthy.

    *Steve Jorgensen*

*   Use config['encoding'] instead of config['charset'] when executing
    databases.rake in the mysql/mysql2. A correct option for a database.yml
    is 'encoding'.

    *kennyj*

*   Fix ConnectionAdapters::Column.type_cast_code integer conversion,
    to always convert values to integer calling #to_i. Fixes #7509.

    *Thiago Pradi*

*   Fix time column type casting for invalid time string values to
correctly return nil.

    *Adam Meehan*

*   Fix `becomes` when using a configured `inheritance_column`.

    *Yves Senn*

*   Fix `reset_counters` when there are multiple `belongs_to`
association with the
    same foreign key and one of them have a counter cache.
    Fixes #5200.

    *Dave Desrochers*

*   Round usec when comparing timestamp attributes in the dirty tracking.
    Fixes #6975.

    *kennyj*

*   Use inversed parent for first and last child of has_many association.

    *Ravil Bayramgalin*

*   Fix Column.microseconds and Column.fast_string_to_date to avoid converting
    timestamp seconds to a float, since it occasionally results in inaccuracies
    with microsecond-precision times. Fixes #7352.

    *Ari Pollak*

*   Fix `increment!`, `decrement!`, `toggle!` that was skipping callbacks.
    Fixes #7306.

    *Rafael Mendonça França*

*   Fix AR#create to return an unsaved record when AR::RecordInvalid is
    raised. Fixes #3217.

    *Dave Yeu*

*   Remove unnecessary transaction when assigning has_one associations
with a nil or equal value.
    Fix #7191.

    *kennyj*

*   Allow store to work with an empty column.

    Fix #5872.

    *Ivan Evtuhovich*

*   Make sure `:environment` task is executed before `db:schema:load`
or `db:structure:load`
    Fixes #4772.

    *Seamus Abshere*


*Active Resource*

* No changes


*Active Support*

*   Add logger.push_tags and .pop_tags to complement logger.tagged:

        class Job
          def before
            Rails.logger.push_tags :jobs, self.class.name
          end

          def after
            Rails.logger.pop_tags 2
          end
        end

You should have a more useful message than that somewhere, possibly in
log/test.log if nowhere else. Otherwise what message do you get when
you try to load one of the pages in a browser?

After giving some serious thought to this matter and reading all your
advices my last thinking was "I really don't have that high knowledge of
js nor ajax so lets search the solution in other way, more
rails-already-implemented solution"

So I found this plug-in called Pageless that is designed for rails and
after some work I could made it work.

Ruby on Rails

Hi, 


I am trying to work through the Ruby on Rails 3 Tutorial book. I got stuck on chapter 5, trying to get the routes.rb file changed into:

match '/signup', :to => 'users#new' 
match '/contact', :to => 'pages#contact'
match '/about', :to => 'pages#about'
match '/help', :to => 'pages#help'
root :to => 'pages#home'

It used to be "get" instead of "match". I have made the changes to the other files the book recommends, but the pages have since stopped loading and the tests are failing.
rspec ./spec/controllers/pages_controller_spec.rb:27 # PagesController GET 'contact' should be successful
rspec ./spec/controllers/pages_controller_spec.rb:31 # PagesController GET 'contact' should have the right title
rspec ./spec/controllers/pages_controller_spec.rb:49 # PagesController GET 'help' should be successful
rspec ./spec/controllers/pages_controller_spec.rb:53 # PagesController GET 'help' should have the right title
rspec ./spec/controllers/pages_controller_spec.rb:38 # PagesController GET 'about' should be successful
rspec ./spec/controllers/pages_controller_spec.rb:42 # PagesController GET 'about' should have the right title
rspec ./spec/controllers/pages_controller_spec.rb:14 # PagesController GET 'home' should be successful

rspec ./spec/controllers/users_controller_spec.rb:7 # UsersController GET 'new' returns http success
rspec ./spec/controllers/users_controller_spec.rb:11 # UsersController GET 'new' should have the right title
rspec ./spec/requests/layout_links_spec.rb:10 # LayoutLinks should have a Contact page at '/contact'

HELP!!!

Ruby on Rails

I code this on my controller:

 caches_page :index
 cache_sweeper :site_sweeper

https://github.com/leandromoreira/playground.activeadmin/blob/master/app/controllers/page_controller.rb

and this on my sweeper

class SiteSweeper < ActionController::Caching::Sweeper
    observe Article, Category

    def after_create(model)
      expire_cache_for(model)
    end

    def after_update(model)
      expire_cache_for(model)
    end

    def after_destroy(model)
      expire_cache_for(model)
    end

    private
    def expire_cache_for(model)
      expire_page controller: 'page', action: 'index'
    end
end

https://github.com/leandromoreira/playground.activeadmin/blob/master/app/sweepers/site_sweeper.rb

But I change my Article and the change do not expire the page, am I doing something wrong?

2012/10/31 Walter Lee Davis <waltd@wdstudio.com>:

> Is your server configured to host in SSL mode? It's not just a matter of changing the URL in the browser, you have to have configured the server to listen on port 443, purchase and configure a security certificate in Apache or Nginx, and you have to configure Rails to serve in secure mode. For this last part, I really like the rack-ssl Gem.

Since it already works for one https-URL and not for the other one, I
suggest that it is set up everythin to work with SSL, but the
certificate is on the wrong URL (www.example.com instead of
example.com + Subdomains)

Norbet is correct. You need to purchase a wildcard certificate to cover mutiple host names.  if you purchased the cert for www.example.com, it is only good for that name.  If you want to host mutiple names with the same certificate (provided they are in the same domain) you need to purchase a special certificate called a wild card certificate.  This would cover xxx.example.com, yyy.exmple.com, example.com, etc.

Without to know the actual URL of the server it is not possible to check that, also you are missing what kind of error you get, so I can only guess that your certificate is for www.example.com and doesn't include example . com without www.

The best advice I have seen on this topic so far is to first walk, then run. Start by setting up traditional (kaminari, will_paginate) pagination. Get that working solidly. Then layer on the JavaScript to call that pagination in your page, based on the simple test: "is this marker item visible on screen or not?".

The benefit to this approach is that you silently cater to non-scripted visitors, like Google, who you ignore at your peril.

Is your server configured to host in SSL mode? It's not just a matter of changing the URL in the browser, you have to have configured the server to listen on port 443, purchase and configure a security certificate in Apache or Nginx, and you have to configure Rails to serve in secure mode. For this last part, I really like the rack-ssl Gem.

Sorry, use a collection, not a member:

resources :users do
collection do
get 'login'
end
end
root :to => 'users#index'

rules order in routes.rb is important: users resource 'users/:id'
matches before 'users/login' so login is the id :)
you can invert the order of the rules or, better, use a member:

Cbapp::Application.routes.draw do
resources :users do
member do
get 'login'
end
end
root :to => 'users#index'
end

I suggest your best plan might be to work right through a tutorial on
rails to help you to understand the basics. railstutorial.org is good
and is free to use online. Make sure that any tutorial you use is for
Rails 3 and that you use exactly the right version of rails that the
tutorial expects.

FAFAFA is not a valid value for background, and you should be using
background-color if you only have a colour just for semantics but to
directly address your question, please try doing #fafafa, please also
note that the pseudo class for hover is :hover so try .post:hover
instead of .post.hover.

Hi everbody,

I'm new in the forum. I' studing ruby and rails and I hope learn faster
with the help of the forum.

Well, my problem is basic. I have made a scaffold to create a new object
User. User has name, email and password.

I created a new view named "login", but i don't know how to make the
route to this view. I Have the function in the controller too.


Cbapp::Application.routes.draw do
resources :users
root :to => 'users#index'
match 'users/login' => 'users#login'
end


and I got this error: Couldn't find User with id=login

Thanks!

Ruby on Rails

From the question you have posed, and the information you have provided, there is not a simple 'do this' answer.  You need to get a bit further down the path of what you want to achieve.  (unless someone knows some magic foo that I am unaware of).

Looking at what you have so far, it would seem that you have the basic functionality of the page, and you have an idea of what you want to achieve, but you do not yet appear to have a strategy or plan for how you are going to achieve it.  I have never implemented continuous scroll, but giving it some cursory thought, I would begin by asking myself some questions.

1.  How is the page update going to take place when I extend the contents.  
     eg.  - replace the whole page each time the list updates
            or -  replace the list section 
            or - add additional items at the end
     Do I let the page size continue to grow indefinitely or do I remove some items from the other end.

2.  If I am going to manage addition/deletion of items.  The items will probably be best structured in an an html list or table, and each may need a unique id, or can I just append/prepend  to the list of items.

3. What mechanism will I use to identify the next 'page' of items I want to add to the list.

4.  How is my controller going to get the correct list of items to add? ie what paging mechanism am I using.

5.  How am I going to handle the ajax response that contains the items.  I am going to need some js code to append/prepend or insert the items into the list.  

6.  What form will my response be in.  I can send some javascript using an erb template to insert the items, or I could have a js function on the browser side ready to handle the response (eg as a success callback handler.)  Or I could return data as json and handle the paging more fully in the browser js.

7.  Finally having thought about all this, I would do some googling to see if someone has already implemented such a thing in a form I could learn from, or is there maybe a js library that might already provide most of the functionality I require.  

I am sorry this is not a direct answer, but hopefully it may help to clarify what you are trying to achieve and how you are going to go about it.

Ruby on Rails

In rails 2.3.5 (with active scaffold) all my columns in display were
sorted even though they belonged to a related table. But in Rails 3.2.8
, only columns which belong to the main table are sorted .To sort a
related table column we need to specifically add the line below

columns[:columnfromtable2].sort_by :sql => ['name']

I have many columns which are 'related' in many pages , it would be
tedious to add this line in them all

Without to know the actual URL of the server it is not possible to check that, also you are missing what kind of error you get, so I can only guess that your certificate is for www.example.com and doesn't include example . com without www.

For me, most of the time there is not, actually they add overhead IMO

helpers that generate generic left_text_area and other methods like it
that just add the classes I need for forms and wrap the <section>'s
around the generic helpers that Rails already provides. That is,
instead of including another dependency that I don't need, but for
some people they bring great benefit because they can handle HTML from
step 1 to end, I don't like that because I prefer to directly control
every bit of output my app makes.

Only you can evaluate whether or not they are worth it, it's a battle
of your own to fight, I can honestly say I would use them if I
actually had a use for them, and many people will agree they have a
use for them, but I personally don't have a use for them so I choose
not to use them. You have to evaluate that for yourself.

FAFAFA is not a valid value for background, and you should be using
background-color if you only have a colour just for semantics but to
directly address your question, please try doing #fafafa, please also
note that the pseudo class for hover is :hover so try .post:hover
instead of .post.hover.

Hi all,

for some reason adding the following is doing nothing...

.post.hover  {
background: FAFAFA;

I've got this in my posts.js coffee file

$ -> 
$('.post').hover (event) ->
$(this).toggleClass("hover")

and my index is

<% @posts.each do |post| %>
<div class="post">
<strong><%= post.title %></strong>
<p><%= post.content %></p>
<div class="meta">
<%= link_to time_ago_in_words(post.created_at) + " ago", post %>
<span class="admin">
| <%= link_to "Edit", edit_post_path(post) %> |
<%= link_to "Delete", post, :confirm => "Are you sure you want to delete this post?", :method => :delete %> |
</span>
<div>
</div>

<% end %>


Any ideas?

I agree with you totally man. Not to mention Heroku only gets
expensive before you add in the tax on sysops. One might might
ignorantly assume that Heroku is expensive but in essence it's a lot
cheaper. At 2 dynos which is $35... to have the same setup of your
own would cost you twice as much.

To get 3 dynos having the same setup of your own only saves you around
$11 but after that one would need a systems administrator to manage
all these instances or at least a part time one to help you manage the
infrastructure that manages those -- that is unless you put it all on
one server, then there is no helping you anyways -- that or you like
to waste time not programming by managing your own clusters which is
fine by me but at that point you would save money at a cost of
development time which still ends up costing you money in the end, in
some way.

So what I am saying is, once somebody starts factoring in all the
costs, Heroku isn't all that expensive compared to what you could be
paying by doing it yourself, people choose to go their own route
because of infrastructure needs not because of the price of Heroku..
because people who actually plan out the numbers and look at Heroku's
infrastructure start to realize just how much it isn't expensive.

This is all based off of a single site and not something like a system
like Heroku that you manage on your own for your clients because the
other could lead to quite a few cost savings in some places but IMO it
probably won't be enough to justify the huge startup cost.

If you have a simple application, try railsplayground.com

it's very cheap and easy to deploy. (you may need some unix knowledge)
