Strange problem with "each"

Rails
1

Hello all,
This is my first time setting up associations in Rails. A User :has_many
Jobs, and a Job :belongs_to a User.

Take a peak at this code and tell me what you think. For some reason,
when I pull these jobs and try to iterate through to show a list of Jobs
posted by a User, I get a strange error with the “each” function.

Thanks much.

This is part of your problem:

@user.jobs.find_by_user_id(@user.id, :all)

Since you are accessing jobs through the @user instance, you don’t
need to specify the “find by user id”. Rails already knows to only
find jobs associated with that user.

You can just do this: @user.jobs

And this: @user.jobs each do | job |

Make sure you have “has_many :jobs” in your User model. Didn’t see
that posted in your code.

Also, might not be a bad idea to familiarize yourself with the Rails
Association documentation. It will answer a lot of questions like
this.

Hi Tim,
I implemented your changes. Unfortunately, I still got the same error. I
copied both the User and Jobs models, as well as the schema.rb file.

Please let me know your thoughts.

You have a minor typo in index.html.erb

<% unless @user.jobs == nil %>
  <% @user.jobs each do |job| %>
    <%= job.Title %>
  <% end %>
<% end %>

You want @user.jobs.each not @user.jobs each. Note the missing
dot between “jobs” and “each”.
