问题 I have a Rails 3.2 ajax form that creates a new Room for a Hotel. The new Room ajax form works correctly on the Room index page, but once I embed the new Room ajax form on a Hotel edit page, the form is submitted normally without using Ajax. To create the new Room form, I use the following link on the Hotel edit.html.erb page: <%#= link_to 'Add a Room', new_room_path(:hotel_id => @hotel.id), :remote => true, :class => 'new_room' %> This loads the following form partial on to that same page: <

问题 I'm creating my first Rails 3.2 application after completing the excellent Rails Tutorial. I would like my application to do this: Pull a random recipe from the database (I have finished this bit using the 'index' action and this bit of code: @recipe = Recipe.find(:first, :order => 'Random()')) If the user clicks the 'something similar' button, the app fetches a related recipe from the db If the user clicks 'something different', the app fetches an unrelated recipe From what I understand,

In the Index action of my Users controller, I have the following code: def index @users = User.same_city_as(current_user) end @users is an ActiveRecord::Relation object. @users is essentially capturing all the users who belong to the same city as the current_user .

问题 I recently implemented versioning on my API project. Now URLs of my api will have to be prefixed by the sequence /v1/ (As I'm currently on v1) I don't want to break old calls, so to ensure transparent compatibility, I want to rewrite the old urls.

We're trying to put together end-to-end blackbox regression and integration tests that demonstrate that when you upload a certain file to the first app, you can count on getting a certain file out of the other app. The question is how to script this, so that the two separate databases are reset with seeded values, the two servers are fired up and
