问题描述
我正在尝试同时创建一个资源和另一个嵌套资源.我正在使用Rails4和simple_form 3.0.0rc.这是我的代码.
I'm trying to create one resource with another nested resource at the same time. I'm using Rails4 and simple_form 3.0.0rc. Here is my code.
class User < ActiveRecord::Base
has_one :profile
accepts_nested_attributes_for :profile
end
class Profile < ActiveRecord::Base
belongs_to :user
end
控制器:
class UsersController < ApplicationController
def new
@user = User.new
@user.build_profile
end
def create
user = User.new user_params
user.save
redirect_to root_url
# @par =params
end
private
def user_params
params.require(:user).permit(:email, profile_attributes: [:name])
end
end
查看(适用于新用户的表单)
<%= simple_form_for @user do |f| %>
<%= f.input :email %>
<%= simple_fields_for :profile do |p| %>
<%= p.input :name %>
<% end %>
<%= f.submit %>
<% end %>
当我提交表单时,create
操作会收到以下params
:
When I submit the form, the create
action receives this params
:
{"utf8"=>"✓",
"authenticity_token"=>"dJAcMcdZnrtTXVIeS2cNBwM+S6dZh7EQEALZx09l8fg=",
"user"=>{"email"=>"vasily.sib@gmail.com"},
"profile"=>{"name"=>"Vasily"},
"commit"=>"Create User",
"action"=>"create",
"controller"=>"users"}
在调用user_params
之后,剩下的唯一内容是
And after calling user_params
the only thing that left is
{"email"=>"vasily.sib@gmail.com"}
而且,如您所见,profile
没有任何内容,因此不会创建任何配置文件.
And, as you can see, there is nothing about profile
, so no profile will be created.
我在做什么错了?
推荐答案
使用f.simple_fields_for
代替simple_fields_for
:
<%= f.simple_fields_for :profile do |p| %>
<%= p.input :name %>
<% end %>
