Question

I have a relationship like this

class User
  include Mongoid::Document
  include Mongoid::Timestamps

  embeds_one :setting
end

and the setting class

class Setting
  include Mongoid::Document
  include Mongoid::Timestamps

  embedded_in :user

  field :notify, type: Boolean
end

and I have a form like this:

<% form_for current_user.setting || current_user.build_setting, :html => {:class => 'well'} do |f| %>
  Notificar: <%= f.check_box :notify, :class => 'check' %>

  <div class="form-actions">
    <%= f.submit "Salvar" %>
  </div>
<% end %>

but when I access the form page, the form isn’t shown. I suspect that it’s because setting is nil, or something like that…
What am I missing?
Thank you guys

Answer 1

You are missing an equal sign in front of form_for.

<%= form_for # ... %>

The form_for helper renders all the stuff in its block, adds a form tag and returns the html. In order to display it, you have to tell eRB you want to display the returned string. So when the equal sign is missing, it will just not display the output.
