나는 많은 관계로이 일이 중첩 특성 (accepts_nested_attributes_for)을 형성레일이
이> params = { programa: { nombre: 'nuevo', roles_attributes: [ {name: 'role1'}, {name: 'role2'}] }}
> p = Programa.create(params[:programa])
> p
=> #<Programa id: 7, nombre: "nuevo", descripcion: nil, created_at: "2013-10-09 14:07:46", updated_at: "2013-10-09 14:07:46">
> p.roles
=> [#<Role id: 15, name: "role1", description: nil, created_at: "2013-10-09 14:07:46", updated_at: "2013-10-09 14:07:46", programa_id: 7>, #<Role id: 16, name: "role2", description: nil, created_at: "2013-10-09 14:07:46", updated_at: "2013-10-09 14:07:46", programa_id: 7>]
하지만 그것은 응용 프로그램에서 작동 할 수 없습니다를/뷰/programas/_form :
<%= form_for(@programa) do |f| %>
<%= render 'shared/form_error_messages', object: f.object %>
<div class="field">
<%= f.label :nombre %>
<%= f.text_field :nombre %>
</div>
<div class="field">
<%= f.label :descripcion %>
<%= f.text_field :descripcion %>
</div>
<% f.fields_for :roles do |builder| %>
<div class="field">
<%= builder.label :name %>
<%= builder.text_field :name %>
</div>
<div class="field">
<%= builder.label :description %>
<%= builder.text_field :description %>
</div>
<% end %>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
내가 내 양식을 만들기 위해 추가하거나 제거 할 수있는 다른 있나요은 N 역할을 보여줍니다 ested 속성?
이 programas 내 컨트롤러입니다 :
class ProgramasController < ApplicationController
# GET /programas
# GET /programas.json
def index
@programas = Programa.all
respond_to do |format|
format.html # index.html.erb
format.json { render json: @programas }
end
end
# GET /programas/1
# GET /programas/1.json
def show
@programa = Programa.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.json { render json: @programa }
end
end
# GET /programas/new
# GET /programas/new.json
def new
@programa = Programa.new
respond_to do |format|
format.html # new.html.erb
format.json { render json: @programa }
end
end
# GET /programas/1/edit
def edit
@programa = Programa.find(params[:id])
end
# POST /programas
# POST /programas.json
def create
@programa = Programa.new(params[:programa])
respond_to do |format|
if @programa.save
format.html { redirect_to @programa, notice: 'Programa was successfully created.' }
format.json { render json: @programa, status: :created, location: @programa }
else
format.html { render action: "new" }
format.json { render json: @programa.errors, status: :unprocessable_entity }
end
end
end
# PUT /programas/1
# PUT /programas/1.json
def update
@programa = Programa.find(params[:id])
respond_to do |format|
if @programa.update_attributes(params[:programa])
format.html { redirect_to @programa, notice: 'Programa was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: @programa.errors, status: :unprocessable_entity }
end
end
end
# DELETE /programas/1
# DELETE /programas/1.json
def destroy
@programa = Programa.find(params[:id])
@programa.destroy
respond_to do |format|
format.html { redirect_to programas_url }
format.json { head :no_content }
end
end
end
난 그냥 중첩 된 속성이 편집에 표시 및 작업 만 표시되고 싶어요.
컨트롤러 동작은 어떻게됩니까? –
