I am getting a strange error in my TDD Rails Workshop that I can't figure out

Testing Test-Driven Rails Tutorial
1

At about the 12.5 minute mark into the 3rd “lesson” on unit testing, we are told to run specs for the manage_todos_spec.rb and that they should be working.

This is right after changing this code on line 14. below. Strangely, I’m getting an odd error when I run the tests for manage_todos_spec.rb. I’ve compared my code to others who are slightly further along and can’t find what is different.

Any ideas?

Looks like your test database is missing that column.

Have you prepared your test database with rake db:test:prepare after running the migrations?

I have indeed, sir. :smile:

rake db:migrate; rake db:test:prepare

I’ve opened up the console and created a user with an email address, and some todos with that email, and I can do fake_user.todos in the console without any trouble.

I’m mystified. Why in the error does it say "no such column ‘owner_email.current_email’. I’m new at deciphering this kind of thing. The way the lesson is set up, Todo is a model with a corresponding table in the db, with only two columns: description and owner_email.

sigh. I know this is hard to figure out via forum posts. I’ve spent 90m on it and I can put in some more. Frustrating b/c I was cruising through that lesson like Thelma and Louise.

Looking at the SQL:

SELECT "todos".* FROM "todos" WHERE "owner_email"."current_email" = 'person@example.com' AND "owner_email"."todos" IN (NULL)

There is no join from the owner_emails table.

But it could be your not adding the user correctly.

@todo.user_id = current_user.id

Or maybe it should be

  @todo = Todo.new(params[:todo])
  @todo.save
  @todo.user << current_user

Need to know more about your model relationships to give more help.

class Todo < ActiveRecord::Base
attr_accessible :description, :owner_email
end

And…

class User
attr_reader :email

def initialize(email)
@email = email
end

def todos
Todo.where(owner_email: email)
end

end

What else might help out?

I found it; it was a small change in the application controller. thanks for the attention, though.

Phil,

Do you remember what you changed? I’m having the exact same issue and can’t figure it out.

Chris I just went through to see if I had the project with its commit history, and I don’t. So sad.

That was a loser move on my part to not be specific in my post above. Sorry about that.

Here is an application controller from a todo app that I had; I’m not 100% sure it is the same one I was using doing the tutorial but you might compare it to what you have and see if anything jumps out at you:

class ApplicationController < ActionController::Base
     protect_from_forgery
  
     def sign_in_as(email)
       session[:current_email] = email
     end
  
     def current_user
       User.new(session[:current_email])
     end
 
    helper_method :current_user
  end

That’s what I have. Oh well…thanks for taking a look.

Oops, I should have copied and pasted what you sent. I had

def current_user
  User.new(session:[:current_email])
end

Notice the":" after session which is wrong. Anyway, that’s the difference. Thank you very much!
