在轨道 5 中发布请求

Question

嗨，我在通过表单将数据填充到我在 rails 应用程序中创建的表中时遇到问题。

我可以使用索引操作查看数据，但是当在控制台中触发创建操作时，数据库中不会永久存储任何内容？

我在config/routes.rb文件中使用了resources

耙子路线：

user_leads GET    /user_leads(.:format)                                                     user_leads#index
POST   /user_leads(.:format)                                                     user_leads#create
new_user_lead GET    /user_leads/new(.:format)                                                 user_leads#new
edit_user_lead GET    /user_leads/:id/edit(.:format)                                            user_leads#edit
user_lead GET    /user_leads/:id(.:format)                                                 user_leads#show
PATCH  /user_leads/:id(.:format)                                                 user_leads#update
PUT    /user_leads/:id(.:format)                                                 user_leads#update
DELETE /user_leads/:id(.:format)                                                 user_leads#destroy

app/controllers/user_leads_controller.rb：

class UserLeadsController < ApplicationController
def index
@user_lead = UserLead.all.order("created_at DESC")
end
def new
@user_lead = UserLead.new
end
def create
@user_lead = UserLead.new(user_lead_params)
end
private
def user_lead_params
params.require(:user_lead).permit(:name, :businessname, :phone, :email, :amount)
end
end

app/views/user_leads/new.html.erb

<%= form_for :user_lead, url: user_leads_path do |u| %>
<p>
<%= u.label :name %>
<%= u.text_field :name %>
</p>
<p>
<%= u.label :businessname %>
<%= u.text_field :businessname %>
</p>
<p>
<%= u.label :phone %>
<%= u.text_field :phone %>
</p>
<p>
<%= u.label :email %>
<%= u.text_field :email %>
</p>
<p>
<%= u.submit %>
</p>
<% end %>

config/routes.rb：

resources :user_leads

当我发出 post 请求时，我的控制台中的输出：

Started POST "/user_leads" for 127.0.0.1 at 2018-09-29 11:28:48 +0100

Answer 1

将控制器中的创建方法更改为：

def create
@user_lead = UserLead.new(user_lead_params)
respond_to do |format|
if @user_lead.save
format.html { redirect_to user_leads_path, notice: 'UserLead was successfully created.' }
format.json { render :show, status: :created, location: @user_lead }
else
format.html { render :new }
format.json { render json: @user_lead.errors, status: :unprocessable_entity }
end
end
end

Answer 2

你需要使用#create而不是#new：

def create
@user_lead = UserLead.create(user_lead_params)
end

Answer 3

应该是：

def create
@user_lead = UserLead.create(user_lead_params)
end
