Can't get rails console to work?

Open terminal and type...

ruby -v

Note that down then do...

rails -v

then post your answer here

Sorry, totally missed that. The error is when you use attr_accessible in your models. That is no longer in rails 4. You should research how it has changed. Mainly, you add a private method in your controller, for example:

def todo_item_params
    params[:todo_item].permit(:content)
  end

Here, the params need a permit method on them, where you permit the column of the database. Then, in the controller action, you would put:

#old method
@todo_item =  @todo_list.todo_items.new(params[:todo_item)
#new method
@todo_item = @todo_list.todo_items.new(todo_item_params)

I highly suggest checking out this new ruby on rails project Jason recently made. http://teamtreehouse.com/library/build-a-todo-list-application-with-rails-4

It explains really well how rails 4 works, and from there you could then conceivably use rails 4 for the Treebook application.

Rails 4 and ruby 2

See here some people got it working with ruby 2 and rails 4 https://teamtreehouse.com/forum/strongparameters-and-treebook

https://teamtreehouse.com/forum/got-a-problem-with-devise-attraccessible-and-rails-4

but i can't get it to work with my own set up.....

i know all this, the problem is that it won't work using ruby 2.0.0 and rails 4.0.2

rails gives me a bunch of error using these tutorial because they aren't up to date...... i just reverted my rvm to older ruby -v and older rails -v so it fixed the problem but the original question i wanted to be answer is that is there a newer work around using ruby 2.0 and rails 4.0.2 using the strong parameters!

i did the error was in the pastebin i posted above

go to your project directory , open project and then type : rails console

Make sure you are in the location of your app. For example, if I have an app called "MyApp" inside my Sites > Projects directory, I'll need to be in there to run the console. So I run:

cd Sites/Projects/MyApp

And then run

rails console
