I wrote that bit of the guide. You definitely do not want to live compile in production. When you have compile on, this is what happens: Every request for a file in /assets is passed to Sprockets.

I think I just figured it out. I changed the (new) default protect_from_forgery with: :exception to protect_from_forgery with: :null_session as per the comment in ApplicationController. # Prevent CSRF attacks by raising an exception. # For APIs, you may want to use :null_session instead. You can see the difference by looking at the source for request_forgery_protecton.rb, … Read more
Have you tried adding a magic comment in the script where you use non-ASCII chars? It should go on top of the script. #!/bin/env ruby # encoding: utf-8 It worked for me like a charm.

If you want to use an OR operator on one column’s value, you can pass an array to .where and ActiveRecord will use IN(value,other_value): Model.where(:column => [“value”, “other_value”] outputs: SELECT `table_name`.* FROM `table_name` WHERE `table_name`.`column` IN (‘value’, ‘other_value’) This should achieve the equivalent of an OR on a single column

You might need to differentiate: Not there at all. There but nil. There but false. There but an empty string. as well. Hard to say without more details … Read more
Just a note that the currently accepted answer is deprecated in Rails 3. You should do this instead: Comment.where(:created_at => @selected_date.beginning_of_day..@selected_date.end_of_day) Or, if you want to or have to use pure string conditions, you can do: Comment.where(‘created_at BETWEEN ? AND ?’, @selected_date.beginning_of_day, @selected_date.end_of_day)
Both will generate the same columns when you run the migration. In rails console, you can see that this is the case: :001 > Micropost => Micropost(id: integer, user_id: integer, created_at: datetime, updated_at: datetime) The second command adds a belongs_to :user relationship in your Micropost model whereas the first does not.
