I am having a hard time trying to write this view. A user has many lawyers and a lawyer can take many services. I want a checkbox which the user can select the services of each lawyer. How can I do it?
<%= form_for @user do |f| %>
<%= f.label :email %><%= f.email_field :email %>
....
<% @user.lawyers.each do |lawyer| %>
<%= f.fields_for :lawyers, lawyer do |lf| %>
<%= lf.label :name, "Nome: " %><%= lf.text_field :name %>
<!-- Everything is working fine so far. However, I can get this to work. A lawyer can have many services: -->
<% Service.all.each do |service| %>
<%= check_box_tag ???, service.id, lawyer.services.include?(service) %>
<% end %>

@contact.errors.messages prints one thing before the form_for block, and another thing after.
<% first_lawyer = @contact.lawyers.first %>
<h1 class="g-title">Contato: <%= first_lawyer.name %></h1>
<%= @contact.errors.messages %> <!-- prints {:sender_name=>["não pode ficar em branco"]} -->
<%= form_for(@contact) do |f| %>
<div class="g-form-label">
Advogado:
</div>
<div class="g-block-div">
<%= first_lawyer.name %>
</div>
