Creating ToDo List App

Hi,

New Rails user here trying to create a basic todolist app in rails 3.2.6
and running into some foreign key issues. Here’s what I did…

I generated scaffolds

list title:string & task description:text listname:string

Next, in order to link the listname for Tasks and the list titles in the
Lists I generated a migration file which looks like this

class AddListIdToTasks < ActiveRecord::Migration
def change
add_column :tasks, :list_id, :integer
end
end

I then added active record association has_many :tasks and for the Task
I used belongs_to :list (, :foreign_key => “list_id)” - even though I
think this last part was unnecessary).

Finally I ran rake db:migrate.

Now I have the table setup (checked it in SQLite Database Browser), but
am running into errors interacting with my forms when I run the rails
server. I know I have some problems with my views and have tried
changing around the _form.html.erb and other .erb files to reflect
:list_id as opposed to :list_name, but I can’t figure out what I need to
do to get the list id into the database table for the tasks. Any ideas
or advice? Would be very much appreciated.

Thank you so much!

What you have shown us looks fine. Have you worked through some
tutorials to show you how to do the basic operations.
railstutorial.org is good and is free to use online. I am sure if you
work right through that then you would have most of your questions
answered.
