Question

I am building a Kid’s Chore App. In application.html.erb I show a side bar listing the children’s names:

  <div id="side">
    <%= link_to "Home", home_path %><br />
    <% @children.each do |child| %>
        <%= link_to child.name, child_path(child.id) %><br />
    <% end %>
  </div>

Upon clicking a child’s name, I want all chores to be displayed.. The code above will “show” the child when clicked.

I am thinking something like:

        <%= link_to child.name, chore_path %><br />

.. this does not work because:

1. I then lose the child_id… which I need for them to record their chores
2. I am routed to http://localhost:3000/chores/1 (I just want the chores index)

How can I keep the child_id as a variable in this example but display the chore index?

Cheers, Chris

Associations below:

class Child < ActiveRecord::Base
  has_many :completion, :dependent => :destroy
  has_many :chores, :through => :completion

class Chore < ActiveRecord::Base
  has_many :completions
  has_many :kids, :through => :completions

class Completion < ActiveRecord::Base
  belongs_to :child
  belongs_to :chore

Answer 1

link_to child.name, chores_path(:child_id => child.id)

Then you can grab the child id in the action with params[:child_id]

The link will be to /chores?child_id=1 for example.
