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 :-/
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.

Some generic questions that can focus the problem.
In which directory is your new .js file exactly?
The new .js file is in app/assets/javascripts
How did you try to "... I have tried manually requiring my file in the
application.js ..."
exact code snippet.
are not comments, but determine which code is included for building the
assets ?
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 ?

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:
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.
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.
