【问题描述】：
我正在构建一个包含客户、站点和报价的报价应用程序。
我有一个属于客户的模型站点。你可以看到下面的模型。
我想创建一个站点并填写如下表格。
由于某种原因，安装简单表单后没有任何保存，我无法创建新站点。
网站管理员
class SitesController < ApplicationController
before_action :authenticate_user!
before_action :set_site, only: [:show, :edit, :update, :destroy]
# GET /sites
# GET /sites.json
def index
@sites = Site.all
end
# GET /sites/1
# GET /sites/1.json
def show
end
# GET /sites/new
def new
@site = Site.new
end
# GET /sites/1/edit
def edit
end
# POST /sites
# POST /sites.json
def create
@site = Site.new(site_params)
respond_to do |format|
if @site.save!
format.html { redirect_to @site, notice: 'Site was successfully created.' }
format.json { render :show, status: :created, location: @site }
else
format.html { render :new }
format.json { render json: @site.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /sites/1
# PATCH/PUT /sites/1.json
def update
respond_to do |format|
if @site.update(site_params)
format.html { redirect_to @site, notice: 'Site was successfully updated.' }
format.json { render :show, status: :ok, location: @site }
else
format.html { render :edit }
format.json { render json: @site.errors, status: :unprocessable_entity }
end
end
end
# DELETE /sites/1
# DELETE /sites/1.json
def destroy
@site.destroy
respond_to do |format|
format.html { redirect_to sites_url, notice: 'Site was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_site
@site = Site.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def site_params
params.require(:site).permit(:name, :client_id)
end
end
网站模型
class Site < ApplicationRecord
belongs_to :client
has_many :quotes
end
新网站表单
<div class="row">
<form class="col s12">
<div class="row">
<%= simple_form_for @site do |form| %>
<% if site.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(site.errors.count, "error") %> prohibited this site from being saved:</h2>
<ul>
<% site.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<%= form.input :name %>
<%= form.association :client %>
</div>
<div class="row">
<%= form.button :submit %>
</div>
<% end %>
</form>
</div>
客户端模型
class Client < ApplicationRecord
has_many :sites
has_many :quotes
end
客户端控制器
class ClientsController < ApplicationController
before_action :authenticate_user!
before_action :set_client, only: [:show, :edit, :update, :destroy]
# GET /clients
# GET /clients.json
def index
@clients = Client.all
end
# GET /clients/1
# GET /clients/1.json
def show
end
# GET /clients/new
def new
@client = Client.new
end
# GET /clients/1/edit
def edit
end
# POST /clients
# POST /clients.json
def create
@client = Client.new(client_params)
respond_to do |format|
if @client.save
format.html { redirect_to @client, notice: 'Client was successfully created.' }
format.json { render :show, status: :created, location: @client }
else
format.html { render :new, notice: 'Client was failed to create.' }
format.json { render json: @client.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /clients/1
# PATCH/PUT /clients/1.json
def update
respond_to do |format|
if @client.update(client_params)
format.html { redirect_to @client, notice: 'Client was successfully updated.' }
format.json { render :show, status: :ok, location: @client }
else
format.html { render :edit }
format.json { render json: @client.errors, status: :unprocessable_entity }
end
end
end
# DELETE /clients/1
# DELETE /clients/1.json
def destroy
@client.destroy
respond_to do |format|
format.html { redirect_to clients_url, notice: 'Client was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_client
@client = Client.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def client_params
params.require(:client).permit(:name, :site_id)
end
end
我没有收到任何错误，我只是无法创建新对象。
