I have a controller method that returns a list for a drop down that gets rendered in a partial, but depending on where the partial is being used, the RJS template needs to be different. Can I pass a parameter to the controller that will determine which RJS gets used? Here is the controller method, it is very simple: def services res...

Say i wanted one of the "Active, Hot, Week" tabs like the ones here on SO. When pressing one of them i want to remove a css class (like "active-tab") from the one ...

On the page is a Rails form for regular text, titles etc., as well as 2 sortable lists; the lists are used for dragging projects from the global-project-list into your portfolio-project-list.

I've seen "RJS" and "RJS templates" mentioned in passing in blog posts and tutorials. I did a search, but I'm still unsure about it. Is it a technology specific to Rails, rather than a standard like JSON or YAML? I understand it's used for "generating JavaScript." Does it generate generic JS or Rails-specific JS requiring the Prototype ...

The dropdown-menu (built by the select_tag) in my application should call the filter-category-action as soon as the user changes the value in the dropdown-menu AND hits the 'Go' button. Now I'd like to get rid of the 'Go' button and have an observer (observe_field?) call the filter-category-action as soon as the user changes the value ...

Is it possible to change a html tag attribute value from an RSJ template? I know that there is a page.replace_html method, but it is not very useful in my case, since I have lengthy values of various attributes (such as alt, title of an image). What I want is change src attribute of a img tag in RJS. Is that possible at all? Thank you. ...
I'm working with an application built in Ruby on Rails with very poor error handling right now. If a controller method is executed via ajax, and that method results in a 500 (or 404 or any other response) the 500.html page is rendered and returned as the result to the AJAX request. Obviously the javascript doesn't know what to do with th...
