belongs_to关联栏的嵌套属性
问题描述:
我有两个模型,投诉和公司。投诉belongs_to
和accepts_nested_attributes
公司和公司has_many
投诉。belongs_to关联栏的嵌套属性
# Models
class Complaint < ActiveRecord::Base
attr_accessible :complaint, :date, :resolved
belongs_to :user, :class_name => 'User', :foreign_key => 'id'
belongs_to :company, :class_name => 'Company', :foreign_key => 'id'
has_many :replies
accepts_nested_attributes_for :company
end
class Company < ActiveRecord::Base
attr_accessible :name
has_many :complaints, :class_name => 'Complaint', :foreign_key => 'id'
has_many :branches, :class_name => 'Branch', :foreign_key => 'id'
belongs_to :industry
end
在投诉控制器中,我尝试在新方法中构建一个公司。
# Complaint Controller
class ComplaintsController < ApplicationController
...
def new
@complaint = Complaint.new
@complaint.build_company
respond_to do |format|
format.html # new.html.erb
format.json { render json: @complaint }
end
end
...
end
在表单中我添加了一个字段,用于向公司添加名称属性。
# Complaint Form
<%= form_for(@complaint) do |f| %>
<% if @complaint.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(@complaint.errors.count, "error") %> prohibited this complaint from being saved:</h2>
<ul>
<% @complaint.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :complaint %><br />
<%= f.text_area :complaint, :rows => 5 %>
</div>
<div class="field">
<%= f.label :date %><br />
<%= f.datetime_select :date %>
</div>
<% if current_user.try(:admin?) %>
<div class="field">
<%= f.label :resolved %><br />
<%= f.check_box :resolved %>
</div>
<% end %>
<%= fields_for :company do |company| %>
<div class="field">
<%= company.label :name, 'Company' %>
<%= company.text_field :name %>
</div>
<% end %>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
表单提交,但只保存投诉。公司的用户输入被忽略。为什么这不会创建一个新的公司?
答
我的错误是在形式。我错过了fields_for :company
<%= f.fields_for :company do |company| %>
