I have the following problem, I have a relationship:
class Servidor < ActiveRecord::Base
has_many :lotacoes, :through=>:servidor_lotacoes
has_many :servidor_lotacoes
end
class Lotacao < ActiveRecord::Base
has_many :servidores,:through=>:servidor_lotacoes
has_many :servidor_lotacoes
end
class ServidorLotacao < ActiveRecord::Base
belongs_to :lotacao
belongs_to :servidor
end
Where ServidorLotacao
has an extra attribute tipo:integer
How can I create a form (ex collection_select
) to manage this relationship in Server, where I can still pass the type to be stored in the relationship table?
I thought about creating 3 multiple selections (one for each type) but getting this information on the other side is a bit complex.
More or less my code:
<% ServidorLotacao.tipos.to_h.each_pair do |tipo_nome, tipo_codigo| %>
<div class="field" >
<%= f.label :lotacao_ids, tipo_nome %><br>
<%= collection_select(:servidor, "lotacao_ids[#{tipo_codigo}]",
@lotacoes,
:id, :nome, {:selected => @servidor.lotacao_ids_for(tipo_codigo), :include_blank => true}, {:multiple => true, class: "select2_1", style:"width: 100%;"}) %>
</div>
<% end %>
And the result in my controller
{"utf8"=>"✓",
"_method"=>"patch",
"authenticity_token"=>"r5KaLCrb1PR//q4HZ0p30dUeK1OHE7cjmtoken=",
"servidor"=>
{"nome"=>"123412312",
"tipo"=>"1",
"lotacao_ids"=>{"1"=>[""], "2"=>["", "87"], "3"=>[""]},
"contatos_attributes"=>{"0"=>{"telefone"=>"(063) 8132-9584", "id"=>"605"}},
"matricula"=>"56830",
"cpf"=>"4539"},
"action"=>"update",
"controller"=>"servidores",
"id"=>"340"}
Where lotacao_ids
are the Ids of my stockings grouped by type. Any ideas?
