Ruby on Rails Treebook — Creating Relationships error.

I really have no idea what I am doing, but this worked. I found on some forums that it could be a problem with my old data so I ran: rake db:migrate:reset

After I did that it worked.... not sure why.

Hello,

In status.rb do you have:

class Status < ActiveRecord::Base attr_accessible :content, :user_id

No, I didn't.

I've just added it though, and my status.rb is as follows:

class Status < ActiveRecord::Base attr_accessible :content, :user_id end

but I still get the error:

NoMethodError in Statuses#new

Cheers.

new.html.erb should just look like:

<h1>New status</h1>

<%= render 'form' %>

<%= link_to 'Back', statuses_path %>

your _form.html.erb should look like:

<%= simple_form_for(@status, html: {class: "form-horizontal"}) do |f| %> <% if @status.errors.any? %> <div id="error_explanation"> <h2><%= pluralize(@status.errors.count, "error") %> prohibited this status from being saved:</h2>

  <ul>
  <% @status.errors.full_messages.each do |msg| %>
    <li><%= msg %></li>
  <% end %>
  </ul>
</div>

<% end %>

<%= f.input :user_id, collection: User.all, label_method: :full_name %> <%= f.input :content %> <div class="form-actions"> <%= f.button :submit %> </div> <% end %>

Right, my new.html.erb is identical.

My _form.html.erb wasn't identical to what you just wrote; it only had:

<%= f.input :user_id %> (and not the rest attributes and methods)

I just added exactly what you wrote for _form.html.erb, and I'm still getting the following error:

Magnus,

Here is the link to the treebook github: https://github.com/jasonseifer/treebook

You can browse through the files in question and see the commit's by either Jason, or Jim.

Once in the file, click history and it will show their commits so you are not looking at onces that reflect a future project.

I hope this helps. I use it for reference when I am stuck and make sure my code is in line. I actually install simple_form before I began this project in my Gemfile, so my code will look different.

Okay,

I'll check it out. Thanks a lot.

I'm having the same exact problem. @magnus, did you ever find a solution?

Same problem here. Please update if you figured out what's wrong!
