I have a bit of javascript magic going on to create and hide divs on the fly as the user interacts with the page. Each div contains a view of some part of my application and each model instance in these views has an owner. If the person browsing the page is NOT the owner, they just see the data. However, if the user is the owner of th...

I need to have a drop down list in which the user selects the day of the week they want to come in every week. The values will never change right. It's just Sunday, Monday, ..., Saturday right? It seems like more work than needed to make a table and put the days of the week in. I certainly don't need the ability to create, update or de...

This follows this prior question, which was answered. I actually discovered I could remove a join from that query, so now the working query is start_cards = DeckCard.find :all, :joins => [:card], :conditions => ["deck_cards.deck_id = ? and cards.start_card = ?", @game.deck.id, true] This appears to work. However, when I try to move th...
I'm using the awesome cache-money gem with a large rails project. I frequently get these exceptions MemCache::MemCacheError: execution expired" There doesn't seem to be a rhyme nor reason. What exactly does this mean, and how to fix? EDIT: Here is a representative stack trace: lib/authenticated_system.rb:100:in `login_from_...

I am moderately new to Rails so this may be a stupid question... I followed the basic steps noted on the github site for the plugin (mainly installed the plugin, ran the generator, modified environment.rb and created the UserObserver class in the models directory) The error I'm getting is saying it's coming from active_support/dependen...

I am trying to reuse some code from another rails application I had worked on earlier. I copied over all the models / views / controller / migrations and ran rake db:create and migrate. Now when I try to run the application the initial page for this view (the one that has the list edit/delete) loads fine and shows there are 0 records. Wh...

I would like to show each user who has visited her/his user profile. At first it looked easy as the acts-as-readable plugin does everything I need. However this plugin does not work from the user model. What if in the future I decided to add visitors to articles, albums etc. /usr/local/lib/ruby/gems/1.8/gems/activerecord-2.2.2/lib/ac...

What data do you use with Selenium tests on Rails apps? Do you load from fixtures? Use an existing dev db? Use a separate (non-fixture) db? I'm considering my options here. I have a Rails app with a large Selenium test suite that runs on a modified version of Selenium Grid. Part of the process, right now, is loading a large set of fixt...
