[Rails] Re: Rails 3.1.0 - Asset pipeline

Ruby on Rails Saturday, December 31, 2011

Found the answer: provided there is an 'assets' subdirectory in the
'myapp/public' directory, it will work and it does work :)

Case closed :)

Happy new year :)

[Rails] Rails 3.1.0 - Asset pipeline

Ruby on Rails

Hi, all :)

Happy new year :)

I referred to http://edgeguides.rubyonrails.org/asset_pipeline.html
for rails 3.1.0,
1) it does say that assets related to the application (ie. need
preprocessing) can live in the myapp/app/assets directory
2) it does say that files which need no preprocessing can still live
in the public/ directory.

I can access files places in the myapp/app/assets directory with no
problems but
how do I access my files in public? For example, public/images/rails-
logo.png?

When I access that path via the webbrowser, I get an error, 'No route
matches [GET] "/public/images/rails-logo.png" '.

thank you

[Rails] Re: 'require_tree .' does not seem to be including the available *.js files as expected. Why?

Ruby on Rails

I looked at 'Upgrading from Old Versions of Rails' in
http://edgeguides.rubyonrails.org/asset_pipeline.html and that has now
fixed the problem whereby files in assets/ can now be accessed.

I followed the changes recommended and they worked.
Nevertheless, I could not see my custom javascript files in the html
when i view its source.

Thank you in advance for any help :)

[Rails] Re: 'require_tree .' does not seem to be including the available *.js files as expected. Why?

Ruby on Rails

I created a new rails app in my /tmp directory.

I noticed that the Gemfile had something new relating to the asset
group.

The app I am working on was created with rails 3.0.x and hence, I made
a change to my Gemfile to use rails 3.1.0 and ran "bundle install" to
get rails 3.1.0 in.

------ This is what I saw in the Gemfile of a new 3.1.0 app I created
(start) --------
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', " ~> 3.1.0"
gem 'coffee-rails', "~> 3.1.0"
gem 'uglifier'
end
------ This is what I saw in the Gemfile of a new 3.1.0 app I created
(end) --------

Seeing that and the fact that I use jquery and not coffee script or
sass (for css),
I altered my own Gemfile of the application which I am encountering a
problem with. See below.

------ This is what my current gemfile looks like (start) --------

source 'http://rubygems.org'

gem 'rails', '3.1.0'

gem 'devise'
gem 'factory_girl_rails' #, "~> 1.2"
gem 'paperclip'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'sqlite3'
gem 'jquery-rails', '>= 1.0.12'

# Gems used only for assets and not required
# in production environments by default.
group :assets do
# gem 'sass-rails', " ~> 3.1.0"
# gem 'coffee-rails', "~> 3.1.0"
gem 'jquery-rails', '>= 1.0.12'
gem 'uglifier'
end

# clean up test db after each spec test run
gem "database_cleaner", "~> 0.6.7"

group :development, :test do
gem "rspec-rails", ">= 2.0.0"
gem "webrat", ">= 0.7.2"
end

------ This is what my current gemfile looks like (end) --------

I restarted my server and yet there's still no luck in accessing the
assets/javascripts/application.js file in my browser :(

Any ideas?

[Rails] Re: 'require_tree .' does not seem to be including the available *.js files as expected. Why?

Ruby on Rails

I had also clicked on 'application.js' in the line, '<script src="/
javascripts/application.js" type="text/javascript"></script>' in the
html file.

It looks like the files in app/assets cannot be accessed.

Here's what the source looks like. Observe the message, 'No route

[Rails] 'require_tree .' does not seem to be including the available *.js files as expected. Why?

Ruby on Rails

Hi, all,

Happy new year :)

Referring to http://guides.rubyonrails.org/asset_pipeline.html, it
seems that 'require_tree .' in myapp/app/assets/javascripts/
application.js will include all *.js files in the myapp/app/assets/
javascripts/.

I have a few other *.js files in this directory : parts.js, makes.js
and categories.js.

Here's an extract from the html file I am viewing:

--------------- Extract start -----------------------

<!DOCTYPE html>
<html>
<head>
<title>My App</title>

<meta content="authenticity_token" name="csrf-param" />
<meta content="jfiFh0CGHgl5F6mX/dORtk1y6IMfnbCavwgx4bVYXbA="
name="csrf-token" />
</head>
<body>

--------------- Extract end -----------------------

My 'app/assets/javascripts/application.js' file is:

--------------- Extract start -----------------------
//= require jquery
//= require jquery_ujs
//= require_tree .

--------------- Extract end -----------------------

My question: I am using rails 3.1.0 and when I open up a page in the
webbrowser and view source, I am not seeing the 3 js files above
being included. Why are the 3 files not included? Is require_tree
broken?

Thank you :)

[Rails] Re: how to pass form values within an ajax call?

Ruby on Rails

1. The following javascript is being defined in myapp/public/
javascripts/application.js

jQuery(function($) {
// when the #search field changes
$("#category").change(function() {
// make a POST call and replace the content
$.post(<%= category_sub_categories_path %>, function(data) {
$("#results").html(data);
});
});
})

2. this javascript is being applied to the myapp/app/views/parts/
_form.html.erb partial template

My question is, if there is a rails variable, @categories in the
partial template, I need to pass the @categories.id value to the
javascript from there.
Would this work?

If somebody understands this and could comment, kindly share your
input.
Thank you

This has nothing to do with Heroku specifically.

I've never used fw_player, but a quick glance at the docs shows it
(apparently) accepts a URL as a 'file' argument. Easiest way to find
out is try it.

Create an Amazon S3 account and upload a video file to it; put that
URL in a page on your development machine. When it works there,
it'll work anywhere :-)

[Rails] how to setting additional attributes of a join model?

Ruby on Rails

I've spent a lot of time trying to create a new model and, at the same
time, setting an attribute of the join model.
I have:
Company
has_many :managements
has_many :managers, :through => :managements

Manager
has_many :managements
has_many :companies, :through => :managements

Then I try to create a new manager with a associated company like this:

- args = @company.nil? ? [@manager] : [[@company, @manager], {:remote => true}]
= simple_form_for *args do |f|

= field_set_tag t('manager.manager') do
= f.input :name
= f.input :surname
= f.input :fiscal_code
= f.input :city
= f.input :zip_code
= f.input :address
= f.input :street_number
= f.input :tel
= f.input :email
= f.simple_fields_for :managements do |p|
= p.input :role

I don't see the field role in the form and I don't know how to set
role when the Management model is created.
How to do this?
Please an advice.
Thanks.

I modified accordion.js by wrapping it in

And everything works.

If I don't do it, the text
(function($) {
})(jQuery);
ends up being displayed on the webpage as the 1st two lines. I didn't see it before.

From a quick look at the link, it also gives you Homebrew (not a good idea
if have MacPorts/fink installed) & it is recommended to run it on a fresh
install of the OS. There is an rvm option.

Bit over the top for my liking...

The machine where you run bundle --deployment, is that a development machine or a deployment machine?? because on http://gembundler.com/ it states

Deploying Your Application

On production servers, you can enable deployment mode:

$ bundle install --deployment

Do not use this flag on development machines. The --deployment flag turns on defaults that are appropriate for a deployment environment. Gems are installed to vendor/bundle and the Gemfile.lock must be checked in and up to date before Bundler is run.

This is how i do it..

After i create the rails app i run

bundle install

then run,

bundle package

which vendors the gems. Now anytime i need to add any new gem I add it to the Gemfile and run 'bundle install' which installs the gem and vendors it too.

At the top of my 'deploy.rb' file i have require "bundler/capistrano" which handles deployment automatically.

This just works for me.

I am having issues loading imagemagick and rmagick on webfaction.

I have installed a rails app called balder that organizes images.

my main problem is that i can't seem to upoload the image sthrough balder.

balder uses imagemagick and rmagick

Well, checking deeper, it seems to use mini_magick by default

and only optionally uses rmagick.

when i use the console and do this:

irb(main):003:0> require 'RMagick'

=> nil

I don't think rmagick is working -- anyone have any ideas?

This page:

https://github.com/espen/balder

says:

- ImageMagicK. Carrierwave can use either RMagicK or MiniMagicK (default). To change resize option the correct gem must be used (specified in Gemfile) and change included setting for Carrierwave in file_uploader.rb

Can be installed from: http://www.imagemagick.org

Looking into that file:

# Include RMagick or ImageScience support

# include CarrierWave::RMagick

# include CarrierWave::ImageScience

include CarrierWave::MiniMagick

Did you change these default settings?

Looking into the Gemfile:

https://github.com/espen/balder/blob/master/Gemfile

...

# -- Photo resizing

# MiniMagick

gem "mini_magick"

# ImageMagick:

#gem "rmagick", :require => 'RMagick'

# FreeImage:

#gem "RubyInline"

#gem "image_science", :git => 'git://github.com/perezd/image_science.git'

So, probably, if you want to activate rmagick for CarrierWave, you should uncomment

the line with "rmagick" and rerun `bundle install` after that.

But, I would first check why the upload functionality does not work with the

default mini_magick that _is_ most probably installed.

But then again ... this file

resources/DummyHTML/css/joshuaclayton-blueprint-css-05312a805eca539ab85e435cfd94bdedfd12ab2e/lib/blueprint/grid_builder.rb

also tries to require 'rmagick' and install the gem 'rmagick'...

That way the crons can also be maintained when you use capistrano and
they will be deployed to new machines if needed. It makes a great deal
of sense to bundle the application specific crons with he application

Re: [Rails] Re: how to play video in ruby on rails

Ruby on Rails

This playing a video is a new one for me so i am learning it. if u don't know how play a video it does not mean you don't know ROR . New things has to learned only by researching and in that process only i posted it.

Sorry to be harsh, but if you don't know how to code to play videos,
you probably ought to forget about RoR for a bit and start with
learning front-end coding and playback mechanisms. Once you have some
solid tools built up, you can then bring it back into RoR and use Ruby
to draw your video players and source files dynamically.

There are plenty of good places to start, depending on your needs:
http://camendesign.com/code/video_for_everybody
http://sandbox.thewikies.com/vfe-generator/
http://flowplayer.org
http://videojs.com

or simply youtube.com - embedding videos.

You need to know the difference between front-end and back-end tools
(client side and server side). Realizing that RoR will ultimately
deliver front-end code to the user in some form or another

[Rails] how to pass form values within an ajax call?

Ruby on Rails Friday, December 30, 2011

hi guys,
I am now rewriting an existing app (rails 2.3.8) with rails 3.1.x.

As observe_field() is no longer the way to go with rails 3 when ajax
is used, I am trying to rewrite a piece of functionality for when a
select box (drop down) with a div id of 'category' is clicked
(onChange),
-a call is made to the sub_categories controller with the category ID
(from the selected option in the category select box)
-the sub categories belonging to the selected category ID will be
returned and a another select box is to be generated in the div with
id of 'sub_category'.

I'm looking at http://www.simonecarletti.com/blog/2010/06/unobtrusive-javascript-in-rails-3/
and I have a question now.

How do I go about passing a variable value to the javascript that
performs the asynchronous call?

For example, i have :

// Append the function to the "document ready" chain
jQuery(function($) {
// when the #search field changes
$("#category").change(function() {
// make a POST call and replace the content
$.post(<%= category_sub_categories_path %>, function(data) {
$("#results").html(data);
});
});
})

-how do I pass the category id (which is a form value) to the
category_sub_categories_path??
-would the category_id value be valid in the jQuery call?

sounds as if you tinkered with application.js or removed the reference
to it completely and thus jquery isn't loaded at all.

So true. We were asked this question for some freelance work a few
years back, in fact, they insisted on having that "feature" for
security reasons. It took them exactly one week to beg us to take it
away again. 5 minutes pass so quickly: you have a phone call, you get

[Rails] Conflicting libraries: jQuery.js & accordion.js

Ruby on Rails

I have a library conflict between jQuery.js & accordion.js

The first line of accordion.js is

$(document).ready(function() {

Firebug displays
$(document).ready is not a function

I have read http://docs.jquery.com/Using_jQuery_with_Other_Libraries. This link is an explanation of how to resolve the conflict.

To that end I have in a partial haml file

(function($) {
= javascript_include_tag 'accordion.js'
})(jQuery);

The rendered output is
(function($) {
<script src="/assets/accordion.js?body=1" type="text/javascript"></script>
})(jQuery);

but I am still getting the
$(document).ready is not a function
error message.

Is what I am trying to do even legal?

Re: [Rails] Daily Routine

You also might want to have a look at the Whenever gem it provides neat syntax all done with ruby and integrates well with capistrano.

https://github.com/javan/whenever

Hope this helps!

2011/12/30 Peter Hickman <peterhickman386@googlemail.com>

That way the crons can also be maintained when you use capistrano and
they will be deployed to new machines if needed. It makes a great deal
of sense to bundle the application specific crons with he application
itself.

In Prototype, you would use the $$() method with a CSS selector, and that method always returns an array, so you would have to write it as $$('#yourElement').invoke('focus');. jQuery returns either a single element or an array, which is one of the many ways it is icky.

well I was trying to implement a generic method of passing a specific ID variable and having the method in the application_helper.rb so I could selectively assert which field by ID but I ended up just putting the following inside the final </html> tag in my layout...

Which just puts the focus on the first field... not the same but probably good enough for my purposes.

$(document).ready(function() {
$('#yourElement').focus();
});

It's just a matter of making it a CSS selector, rather than an ID selector. In Prototype, you would use the $$() method with a CSS selector, and that method always returns an array, so you would have to write it as $$('#yourElement').invoke('focus');. jQuery returns either a single element or an array, which is one of the many ways it is icky.

Right you are. So, feeling a little like David facing off against
Goliath, I've submitted a ticket:

I hope they go gentle on me!

duh... prototype - I don't think it's useful to load both prototype and jquery as I'm already using a bunch of query.

I'll see if I can figure out how to change that to a jquery friendly method.

View source (in a browser) and see if you have the prototype.js library loaded. focus() is a Prototype method (unless I'm wrong and it's in jQuery as well) and without the library it won't work.

3.1 switched to jQuery, which annoys me, but there is a gem you can add to put things right again.

One other thing to look at -- is your call to set_focus_to_id appearing (in source) below the element it refers to? If it isn't, then you have to wrap your call in an observer callback, so that you are sure that the DOM is ready and knows about the element you're trying to modify.

If your code is at the bottom of your view, then you should be fine, but if it's above the referenced element, or if it's in a content_for :head block, then you have to do something like this:

#prototype-flavored javascript
document.observe('dom:loaded', function(){
//your code here
});
