ActionController::RoutingError after using scaffold

rubyonrails-talk
1

Hey there,

I'm new to Ruby and was following a tutorial found here:

http://stackoverflow.com/questions/545951/ruby-on-rails-link-to-syntax

Anyway, I already had my own MySQL database from PHP development so I decided to try to create a scaffold off of a table 'users'.

I get the following error: ActionController::RoutingError in Users#index

Showing app/views/users/index.html.erb where line #9 raised:

user_url failed to generate from {:controller=>"users", :action=>"show", :id=>#<...>}

The issue is coming from this line: <%= link_to 'Show', user %>

I tried deleting that code and trying this instead: <%= user["user_id"] %> -- where user_id is a field in the users table and it printed the user_id

Is this a known scaffold bug in Ruby installs on Windows? How do I go about fixing it?

Thanks, Lang

My guess is that you havent specified what the primary_key of the users table is. Rails expect it do be "id" if you dont specify it. Try adding "set_primary_key(:user_id)" to your user model if you havent already.

That fixed it! Thanks so much!
