【问题描述】：
好的，伙计们，我有一个与配置文件表相关的用户表，我相信我已经完成了我应该做的所有事情来保存嵌套表单属性，但是它们不会保存到数据库中。我已阅读其他帖子，但似乎没有一个适合或解决方案不起作用。需要明确的是，我在基于 Linux 的系统上使用带有 MySQL 的 Rails 5。 我已经在下面包含了相关文件
用户模型
class User < ApplicationRecord
has_one :profile, inverse_of: :user
accepts_nested_attributes_for :profile, allow_destroy: true
end
配置文件模型
class UsersController < ApplicationController
before_action :set_user, only: [:show, :edit, :update, :destroy]
# GET /users
# GET /users.json
def index
@users = User.all
end
# GET /users/1
# GET /users/1.json
def show
end
# GET /users/new
def new
@user = User.new
@user.create_profile
@user.build_profile
end
# GET /users/1/edit
def edit
end
# POST /users
# POST /users.json
def create
@user = User.new(user_params)
respond_to do |format|
if @user.save
format.html { redirect_to @user, notice: 'User was successfully created.' }
format.json { render :show, status: :created, location: @user }
else
format.html { render :new }
format.json { render json: @user.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /users/1
# PATCH/PUT /users/1.json
def update
respond_to do |format|
if @user.update(user_params)
format.html { redirect_to @user, notice: 'User was successfully updated.' }
format.json { render :show, status: :ok, location: @user }
else
format.html { render :edit }
format.json { render json: @user.errors, status: :unprocessable_entity }
end
end
end
# DELETE /users/1
# DELETE /users/1.json
def destroy
@user.destroy
respond_to do |format|
format.html { redirect_to users_url, notice: 'User was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_user
@user = User.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def user_params
params.require(:user).permit(:username, :password, :user_type_id, profile_attributes: [:id, :user_id, :first_name, :middle_name, :last_name, :phone_number, :cell_number, :email])
end
end
用户表单部分
<%= form_for(user) do |f| %>
<% if user.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(user.errors.count, "error") %> prohibited this user from being saved:</h2>
<ul>
<% user.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :username %>
<%= f.text_field :username %>
</div>
<div class="field">
<%= f.label :password %>
<%= f.text_field :password %>
</div>
<div class="field">
<% if params[:trainer] == "true" %>
<%= f.label :user_type_id %>
<%= f.text_field :user_type_id %>
<% else %>
Nota trainer
<% end %>
</div>
<h2>Account Profile</h2>
<%= f.fields_for :profiles do |client_profile| %>
<%#= client_profile.inspect %>
<div>
<%= client_profile.label :first_name %>
<%= client_profile.text_field :first_name %>
</div>
<div>
<%= client_profile.label :middle_name %>
<%= client_profile.text_field :middle_name %>
</div>
<div>
<%= client_profile.label :last_name %>
<%= client_profile.text_field :last_names %>
</div>
<div>
<%= client_profile.label :email %>
<%= client_profile.text_field :email %>
</div>
<div>
<%= client_profile.label :phone_number %>
<%= client_profile.text_field :phone_number %>
</div>
<div>
<%= client_profile.label :cell_phone %>
<%= client_profile.text_field :phone_number %>
</div>
<% end %>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
新视图
New User
<%= render 'form', user: @user %>
<%= link_to 'Back', users_path %>

-
@user.create_profile这行要去掉，@user.build_profile就够了
