Can't seem to get javascripts to load in rails 3.1.3

Hello all,

I am attempting to add some jquery to an application that I am
developing
but I am having trouble getting my newly created .js file to load. I
have
tried manually requiring my file in the application.js but it still does
not seem to load. Is there anything else that I can check to see why my
.js
file is not loading?

So far after adding my .js file, I have checked the html source and also
looked in the firebug console to see if it loaded and it is not there.
As
for a second measure to see if the file is loaded but I just can’t seem
to
find it I added an alert to the the .js file I wanted loaded and it
never
executed.

I welcome any ideas on how I can resolve this issue. At this moment I am
at
a stand still till I can understand whats going on :-/

Some generic questions that can focus the problem.

In which directory is your new .js file exactly?

How did you try to “… I have tried manually requiring my file in the
application.js …”
exact code snippet.

Are you aware that these lines

…/app/assets/javascripts$ cat application.js

//= require jquery
//= require jquery_ujs
//= require jquery-ui
//= require_tree .

are not comments, but determine which code is included for building the
assets ?

I presume you are now talking about dev environment ?

HTH,

Peter

I am almost certain you are using Rails 3.1 or higher. It has some
new assumptions that you may not be aware of.
I highly suggest you go to RailsCasts and watch/read episode #265.
About 4 minutes into the video, you will have your answer.

I found the RailsGuides guide about the assets pipeline good enough to
understand (and use) it.

Here’s the link:

http://guides.rubyonrails.org/asset_pipeline.html

Good luck!

The new .js file is in app/assets/javascripts

//= require jquery_ujs
//= require jquery-ui
//= require_tree .

Yes I am aware of those lines and I did not remove any of those lines
or modify them. When I placed my .js file in the correct location I
was under the impression that //= require_tree . would pick up that
file so that I would not have to add it manually.

I presume you are now talking about dev environment ?

Yes this is development environment

Thanks for the response soldier.
I just finished looking at railscast 265 as you suggested but
unfortunately it did not tell me anything new. My understanding of
assets came from the rails cast #279 (I believe). I think they are
saying the same thing.

Yes it should. I just added a test.js for fun I see this in the source
of
the
home page:

Is application.js loaded correctly ? Like this:

Vell–

With the asset pipeline, you don’t include assets explicitly at
/assets/application.js

Instead, you use the asset pipeline and let it handle this for you.
Re-read the Asset pipeline Rails guide carefully, make sure your
config.assets settings are correct (remember, “turned on by default”
doesn’t apply if you upgraded from a pre-3.1 rails app – you have to
change the config setting yourself).

The assets get compiled into a folder at public/assets/ but you can’t
include those explicitly because of the asset ID thumbprint hash that
gets added.

type=“text/javascript”>

I never saw my individual .js files. The one I am creating is called
confirmation.js which that was not loaded.

Is application.js loaded correctly ? Like this:

I actually don’t see my application.js file either. I am pretty sure
before I upgraded to rails 3.1.3 from 3.1.0 I at least saw my
application.js file. So now I am even more confused.

Do you have <%= javascript_include_tag “application” %> in your
layout?
