Let's say I created a mountable engine called 'Soho' that has a controller for 'Users'. I can go to /users/1 to see my user with ID 1. Inside 'Soho', I have a application.html.erb for layout. Now let's assume I want to "blend" my engine 'Soho' in an application called 'Soho_test', and I mount my engine at "/". So, in my host application 'Soho_test', I can also go at /users/1 to see my user with ID 1. This is working. My question is : how can I do in my host application 'Soho_test' to apply the 'Soho_test' application.html.erb to the /users/1 (user profile page) instead of the one in the 'Soho'

I have a where operation on a model that returns a single object. But I can't seem to use it in object notation (it appears to return an array with the object at [0]). store = Store.where("some_id = ?", some_id) puts store.name # doesn't work puts store # shows array with the object at [0] Because sometimes you don't know how many objects a query should return, so for consistency you always get an array. To get a single object use store = Store.where("some_id = ?", some_id).first If you are looking for the primary ID of the model, you can also use store = Store.find(some_id) which will raise a

I'm just starting with Devise and Rails3. I have the Authenetication down and working and understand the basics. As of now in my Home Controller that represents my Home/Front Page i have two links one that links to Register => sign_up and one that changes depending on login/logout => sign_in/sign_out. However i dont want to redirect my user to login page. Instead i want to display my login form on my front page. So i have seperated the devise/session/new template int to a view and a _form.html.erb partial. And now in my home view i render the login form as so: <% if user_signed_in? %> Welcome:

I have finally started upgrading my Rails apps from 2.3.8 to 3.1.0. I was watching RailsCasts ( http://railscasts.com/episodes/202-active-record-queries-in-rails-3 ) about Active Record queries. When I open up the console (rails c) and do query similar to this: articles = Article.order("name") Instead of returning Active Record relations, I see the query executed. What am I doing wrong here? Rails version: 3.1.0 RVM on 1.9.2 Thank you for your help! EDIT: I have added a screenshot from the example. You're doing everything right. You see query executed because console invokes inspect method on

I have rspec suite for parent app, and also some spec for engines attached. What I want is to run them with one command. Is there a way to include my gems paths into rspec load path? Or should I write rake task for this? I think this is an interesting question, but my opinion is that Rails Engines should be treated as an independent code base and therefore not tested in your parent app. The effect is that you'd treat a Rails Engine in your parent app much like you treat other gems (EG, devise, which is actually a Rails Engine). But let's say you have parent app functionality that relies on a
