I have the following coffeescript file that I wish to include:

app/assets/javascripts/groups.js.coffee

I have an application file - app/assets/javascripts/application.js that has:

//= require_tree .

My views/layouts/application.html.haml file includes: 

= javascript_include_tag :defaults = javascript_include_tag "jquery-ui-1.8.22.custom.min.js"

My page does not seem to have the groups.js file

It does get the jquery-ui-1.8.22.custom.min.js but I'm not sure where from.

I tried putting = javascript_include_tag "groups.js" in
views/layouts/application.html.haml and restarted the server and that does then have a groups.js referenced in the header but clicking on that actual file (in the browser show view) shows this:

<!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8" /> <title>Action Controller: Exception caught</title> <style> body { background-color: #fff; color: #333; } body, p, ol, ul, td { font-family: helvetica, verdana, arial, sans-serif; font-size: 13px; line-height: 18px; } pre { background-color: #eee; padding: 10px; font-size: 11px; } a { color: #000; } a:visited { color: #666; } a:hover { color: #fff; background-color:#000; } </style> </head> <body> <h1>Routing Error</h1> <p><pre>No route matches [GET] &quot;/javascripts/groups.js&quot;</pre></p> </body> </html>

and I also tried putting //= require_tree . in
app/assets/javascript/application.js but just got an error messages that the file wasn't found (javascript/groups.js)

I also tried rake assets:precompile but that gives a strange error about Please install the pg adapter: gem install activerecord-pg-adapter but trying that gives ERROR: Could not find a valid gem activerecord-pg-adapter (>= 0) in any repository

I have no idea what that is about as the application is working full both locally and on remote, using the database with no problem, so it's probably a separate issue. I mention it in case you suggest rake assets:precompile is needed, however to have the assets used in development this should not be an issue (I think).

Originally the app was rails 2.3.8 but now it 3.1.8 - hmm, this be may key if assets came in 3.2+

    Add =javascript_include_tag "application" and check by restarting the server if it works for you

    Then guess the coffeescript file is not being compiled afterall. Why don't you create a simple group.js file in app/assets/javascripts with anything (say alert("FOO")) and then check if that file is available.

  • Upgraded to rails 2.3.8 didn't help though. the groups.js file is very simple (only 5 lines long).

You might want to make sure that:

config.assets.enabled = true

is present in application.rb.

  • @MichaelDurrant ahh gotcha. Would you maybe be willing to post the dev env config?

  • @MichaelDurrant also, which version of rails are you using now?

  • rails 3.1.8 and I think that is the problem. I've changed it to rails 3.2.8 and trying that

    Is config.assets.enabled = true present in application.rb under the config directory?
