I am assuming I have routing issues in my app. Not sure what broke.

What is going on?

I made it to this video and while playing with my app to be sure everything is working and not just passing tests I can see that my "List items" link within the index of the to do lists just keeps showing the same list. It's always the first list in the array.

What I have done:

  • I have checked my routing, I think it's right.
  • I have checked the link syntax in the index view page, I think it's right.

Here is my github repository

What do you guys think? Please help. I've been trying to fix this for hours.

Make sure you download the code from that stage provided by Jason (under the video in the Download section) and compare his files with your files.

Also, if it turns out your code is identical, try running Jason's app to see if he has the same behavior and let me know here what you find.

Found it.

I was able to find it using "DiffMerge" - A great free tool if you don't have it. I checked myself against the provided application files. I found the following error.

I had this:

class TodoItemsController < ApplicationController
  def index
    @todo_list = TodoList.find{params[:todo_list_id]}
  end

  def new 
    @todo_list = TodoList.find{params[:todo_list_id]}
    @todo_item = @todo_list.todo_items.new
  end

It should have been this:

class TodoItemsController < ApplicationController
  def index
    @todo_list = TodoList.find(params[:todo_list_id])
  end

  def new 
    @todo_list = TodoList.find(params[:todo_list_id])
    @todo_item = @todo_list.todo_items.new
  end

The difference was using { } instead of ( ). Should of known better. Thank you treehouse community!

You have a typo in your code:

<li><%= link_to "List items", todo_list_todo_items_path(todo_list) %></li>

Should be:

<li><%= link_to "List Items", todo_list_todo_items_path(todo_list) %></li>

Thanks for catching that... Didn't fix the routing issue though... Still looking into that.
