• JS and Rails site wide announcements

  - by pcasa

  Tried doing http://davidwparker.com/2008/09/17/site-wide-announcements-in-rails-using-jquery-jgrowl/ Am really bad with JS. Think I am messing up on the last part where it says "This code goes in your application.js file (somewhere in $(function){ //here })" Am I not suppose to do a link_to_function and create a function with this code that references that link? Really lost on this one.

  - by Dave Paroulek

  Is it possible to configure rails to show logger.debug messages (from logger.debug statements inside controllers) to display inside test.log (or to the console) when running unit and functional tests? I added the following to test_helper.rb. I see messages from logger.debug statements directly inside tests but no messages from logger statements inside controller methods? def logger RAILS_DEFAULT_LOGGER end

• Rails Association Question (addendum)...

  - by keruilin

  My original question and accepted solution was posted here: http://stackoverflow.com/questions/2483640/rails-association-question. Check that out first. My follow-up question is this: I want to return an object that has both the user attributes and the race attributes. That way I can access, for example, the user's name and the fastest_time. How can this be accomplished? I've tried several approaches, but none I've been satisfied with.

• image protection in rails

  - by Cezar

  Hello, I am looking for ways to protect my product images and I don't know if there's anything out there better than what I've already found: disable right click, use a transparent image in front of your picture and watermarking. Obviously none of them is perfect but I was curious if someone came up with a better solution to this problem. Also is there any rails plugin to aid with that ? Thanks

• Rails: vendor/gems or vendor/plugins?

  - by TheDeeno

  I'm attempting to track my dependencies with git-submodules in my rails app. So far I've added submodules for things like, haml, shoulda, authlogic, etc to 'vendor/plugins'. I've seen indications that I should be using 'vendor/gems' instead though. Question, which directory is the appropriate place to put dependencies being tracked as submodules? Is the choice arbitrary? Thanks

• Loading a page into memory in Rails

  - by titaniumdecoy

  My rails app produces XML when I load /reports/generate_report.xml. On a separate page, I want to read this XML into a variable and save it to the database. How can I do this? Can I somehow stream the response from the /reports/generate_report.xml URI into a variable? Or is there a better way to do it since the XML is produced by the same web app?

• How can I get Rails to interpret a text field as a datetime

  - by doctororange

  My database has a datetime field, and I want to be able to create new entries. Obviously the Rails datetime_select helper isn't the most user friendly thing to have in your form. I'd rather have a text field for the datetime (or one for the date, and one for the time) and interpret the inputs like PHP strtotime can. I might just be searching the wrong keywords. Surely this has been discussed in great depth somewhere. Thanks :0)

  - by Jimmy

  Hey everyone, I am working on a simple blogging type ruby on rails application and I have everything working through tinyMCE for a nice WYSIWYG editor so the user can add some simple things like images/youtube videos and lists. What I am looking for is a nice solution for blacklisting certain elements to be filtered out of the data when it is displayed. So is there a solution for this available as a gem or available to download anywhere? Thanks!
