Question

I’ve built a simple_form form in my rails app and things went just fine:

<%= simple_form_for([@folha, @servico], html: {class: 'well form-horizontal'}) do |f| %>
<%= f.association :pessoa, label: 'Funcionário' %>
<%= f.input :funcao, label: 'Função',collection: @funcoes %>
<%= f.input :modulos, label: 'Módulos', input_html: {class: 'span4'} %>
<%= f.input :valor, label: 'Valor por hora', as: :string ,input_html: {class: 'span1'} %>
<%= f.input :horas, as: :string, input_html: {class: 'span1'} %>
<%= f.button :submit, 'Incluir', class: 'btn btn-primary' %>
<% end %>

To change the order list on the dropdown for the f.association i’ve overwritten the default .all method in Pessoa.rb:

def self.all
  order :nome
end

Then i got this error when trying to render my view:

wrong number of arguments (1 for 0)
Extracted source (around line #5):

2:  <h1>Preencher Pagamentos - Folha <%= "#{@folha.mes}/#{@folha.ano}" %> <small> <%= @folha.obs %> </small> </h1>
3: </div>
4: <%= simple_form_for([@folha, @servico], html: {class: 'well form-horizontal'}) do |f| %>
5: <%= f.association :pessoa, label: 'Funcionário' %>
6: <%= f.input :funcao, label: 'Função',collection: @funcoes %>
7: <%= f.input :modulos, label: 'Módulos', input_html: {class: 'span4'} %>

I think its better find a way to order the list in the view. But im very curious about what
is going on…

You should not override those kind of methods in first place.

Here is how to do it with simple_form

f.association : pessoa, :collection => Pessoa.order(:nome).all
