SV: [Rails] file upload

Ruby on Rails Wednesday, November 30, 2011

You should probably be using sessions, check http://apidock.com/rails/ActionController/Integration/Session for version 2.3.8 and older (I don’t think there is a version 2.3.9?).

[Rails] Re: client name embedded in the url (not subdomains)

Ruby on Rails

1. I wander why the standard way of keeping the user data in the
session does not fit you.
2. scope "(:username)", :username => /[-a-zA-Z]/ do <other routes>
end should help

Can someone guide how to achieve this

[Rails] Re: How can I mock the twitter gem?

Ruby on Rails

Thank you! I was missing the difference between stubbing a method on
the Twitter::Client class vs. instantiating an object via doubling.
Once I figured this out, I fixed my tests.

[Rails] Rails 3 with Ajax on Prototype.js can someone help me with this ?

Ruby on Rails

Hi,

It has been 2 hours that I'm stuck on setting up a rails 3 project to
test it with some Ajax with the Prototype Framework, the problem is
that the tutorial I followed is based on rails 2, and from what I
learned Rails 3 has included some JS Frameworks such Prototype and
jQuery which means that the way to implements those is also different.
help with this please

[Rails] How to use a local copy of rails in a rails application

Ruby on Rails

Sorry for a primitive question, but how can i use a local copy of rails
with my rails 3 application (locally)?

Quick googling didn't help, and on StackOverflow there is something
about putting local rails to the "vendor" directory, but it does not
seem to work for me.

Thanks.

[Rails] routes matching different path for different users.

Ruby on Rails

I want to display different layouts based on user.
If user is "intraOp" the I want to use layout intraOp, if user is
"interOp" I want to display layout interOp while if controller_devise
I want to display application layout.
I based the user selection on request.path.
If request.path is /intraOp then I select user IntraOp, if /interOp
then select user interOp and so on.
The routes.rb is:

match "intraOp" => "companies#index"
match "interOp" => "companies#index"

The problem is that I use pagination.
When the request.path is /interOp companies#index is launched, and are
displayed 10 companies with pagination.
When I click for displaying page 2 companies#index is launched but the
path is not /interOp/companies......... but is
/intraOp/companies.........that is because companies#index is first
matched with "intraOp".
Have you some suggestions to solve the problem to having different
layouts based on user?
I prefer to not create two controllers: intraOp and interOp.

Love it. Apparently that server is rather picky about the requests it's
willing to service :-) Thank you, Treasury Department!

Anyway, try:

>> doc = Hpricot(open(url, "User-Agent" => "MSIE"))
=> #<Hpricot::Doc "\r\n" {doctype "<!DOCTYPE html PUBLIC \"-//W3C//DTD
XHTML 1.0 Strict//EN\" \...

Note: this also works :-)

>> doc = Hpricot(open(url, "User-Agent" => "Zombies from Space"))

(A look through the open-uri docs will be useful for future reference.)

Sounds like a job for Superman, er, I mean, a custom route. Maybe
something like:

match ':client(/:controller(/:action(/:id(.:format))))'

based on the old wildcard router (adding :client at the front). Note
that, as advised in the modern default route.cfg files, this will make
ALL your controllers and actions accessible via GET! If you're OK
with that, go for it. Also depending on how the rest of your normal
routes look (in particular whether you're using nested resources,
renamed routes, etc.), you may need more such lines, which could get
to be a pain.

If you decide to try it, let me know how it works. :-)

[Rails] How to guarantee data integrity for concurrent Rails/Active Record operations

Ruby on Rails

I need to implement a feature for a rails site that will involve
reading and exporting most of my database.

I know this operation is going to take a while. That's fine-- I've got
delayed job for that.

What I'm worried about is the data changing during the running of the
job, and the resulting export being corrupted because of that.

My initial thought was to do all of the reads within a transaction.
However, I would also like to be running the reads concurrently.
ActiveRecord docs say that Transactions cannot be shared between
Connections, and Connections cannot be shared between Threads. So it
looks as though I am restricted to a single thread with this approach.

Any suggestions for a workaround? Is there another way to give the job
a consistent view of the data that doesn't involve transactions? Or is
there some alternative to ActiveRecord/Mysql out there that can
distribute transactions across threads?

brain was typing audited, fingers apparently decided to do something different or perhaps my dog ate my homework.

Yes, acts_as_audited - evokes a time period when it seemed just about every rails inspired gem was acts_as...

Actually it worked very well (acts_as_audited) but again, that was a rails 0.x & 1.x project

[Rails] Re: MS Access integration with Rails through conversion to (Postgres or MySQL) xor direct interaction

Ruby on Rails

I think it is not a good idea to use Access as a datebase.
You could use EMS SQL Management Studio for PostgreSQL to export your
data from access to PostgreSql and then adopt ActiveRecord in your
Ruby project. But you have to adapt the table names and structure as
the ActiveRecord convention or customize the models (http://
2dconcept.com/articles/2-rails-legacy-db-activerecord-conventions).

It is good practice to describe the solution in case anyone finds this

You have a problem with your routes. It is interpreting sign_in as an
id and going to the show action. You may have a route for show/id
before sign_in.
Try
rake routes
in a terminal to see what your routes are.

The browser says it's not redirecting properly so I think another probable cause
is requiring a logged in user for the action that shows the login page. You most

probably have a before_filter that checks if the user is logged in, and if not,
redirects to the log in page.

Show us your routes.rb and the result of rake routes if you cannot work it out.

"bundle exec" makes sure that you're using the executables that ship along with

the gem installed by bundler while running only the command uses the one

recognized by your system.

Like for me bundle exec rspec throws and error while rspec does not.

This usually happens when the rspec bundle exec runs is of a different version.

Try getting the version of the rspec executable that works and change your Gemfile

to use that rspec version. Run bundle install and try running rspec again with

bundle exec.

[Rails] client name embedded in the url (not subdomains)

Ruby on Rails

Hi,

I have already used subdomains in rails 3 and it was straightforward
to setup.

What im trying to do at the moment is have the client name after
the .com/ so its always present www.myurl.com/client_name so i can
grab who the client is and use that throughout their session.

localhost:3000/{client_1}/news
localhost:3000/{client_2}/news

I have searched around and cant really find any examples of this so im
wondering if its possible and/or good practice. I would prefer the
subdomain route but the client specifically wants it setup this way
and im not really sure how best to do it, any advice is appreciated,

[Rails] Re: Some advice to choose framework for a web application

Ruby on Rails

I was a PHP Developer before switching to ROR, and here are some reasons to use RoR.

1. Build a business web application.

Of course :) Almost all frameworks can do this nowadays, including RoR

2. Easy to maintain, update.

Code is highly readable, and Ruby's core priciples include Developer Happiness :)

3. Easy to scalable.

Whatever framework it is, scaling is possible when done correctly. In RoR we use gems like EventMachine

5. Easy to separate test& live environment.

You get a Development, Test and Production environment when you start a new project. Not sure if you can add more, but these 3 are enough for 99% of the cases.

6. Great performance. (We have like 1000 devices is getting data via our)

Oooh yeah :) Ruby is not the fastest language as it's interpreted, but it's still extremely fast for most of our intents and purposes.

7. Easy to deployment.

With the Capistrano gem, we usually do

$ cap deploy

…and done!

8. It already has a many components/modules for general purpose such as: ACL, Authentication, Uploading, Picture processing,...

Yes to all, you have CanCan/Cantango, devise, RMagick/MiniMagick/ImageScience

9. Have a great community behind the framework to support for it.

Agreed. This is one marked difference I found over PHP frameworks. RoR's community is excellent, considering its the community that makes the framework :)

10. Unit testing.

Several excellent gems available, and test driven development is actively encouraged in Rails. A popular and great combination is RSpec/Shoulda

Hi,

This question may asked so many times. I google about it and got lots of discuss generally. After reading all of them, I go to
a conclusion is choose the framework which your understand to it is the most. But we are willing to lean new language or framrwork to make our app better.
So we need some advices to determine which framework we should go with. So I'm posting here, hope
someone can give some advice from real experience when working with ROR and some PHP Framework.

We are developing a web application (it somehows likes a file management sytem with multi users, drag and drop user interface,..). Our application is really a back-end for a system which runs on embedded device. We
are in progress to determine a "good" framework for our need.

Our purposes:
1. Build a business web application.
2. Easy to maintain, update.
3. Easy to scalable.
5. Easy to separate test& live environment.
6. Great performance. (We have like 1000 devices is getting data via our)

8. It already has a many components/modules for general purpose such as: ACL, Authentication, Uploading, Picture processing,...
9. Have a great community behind the framework to support for it.
10. Unit testing.

One thing I notice, code in Ror is very short. To do the same purpose, we can just use some line of code in ROR compare
to PHP. This is better for us. Also we want to use AGILE method in our project. The reason is our product keeps
changing to meet to the need of customer. So I think AGILE method is better than for us than WATERFALL method.

thanks Fred...

valid? indeed works and so does errors and yes, it obviously uses ActiveModel now but since it's LDAP but not user friendly, it's not for the uninitiated.

@group.errors is a mess and @person.errors - fahgettaboutit and will not be useful to someone trying to use the application so I ended up using .to_a.uniq to toss out the dupes...

I finally just worked it out a minute ago with this (in my Person model)

flash[:error] = @person.validate['base'].to_a.uniq.join("<br />")

apparently have to use .html_safe in my view to view the flash[:error] and it's reasonably friendly now.

The files in assets there aren't passed through erb, they're not
supposed to reference application contents etc. They're completely
static js, css etc files that rails does clever stuff to ensure that
they are delivered to clients in a way that is efficient, cache
friendly etc.
If you want a js template to be rendered for your action then it
should live in the same place as your other templates (i.e. app/view/
skills)

You're creating @twitter, stubbing configure on it and so on, but the
code under test is still calling Twitter.configure. Calling
double('Twitter') doesn't replace the existing Twitter constant - you
need to do something like Twitter.stub(:configure) (or
Twitter.should_receive(...), similarly with Twitter::Client.new and so
on

Everytime validate is called you're adding errors, nothing is
resetting errors so it stands to reason that you're going to get
duplicate (or triplicate if validate was called again etc) error
messages.
Given that activeldap seems to be using active model for its
validations stuff it's going to be very close to active record, so you
shouldn't be calling validate directly - call group.valid? to see if
the object is valid and if it isn't look at group.errors
