我是 ROR 编程的新手,我的问题可能看起来是新手!
我有一个 Rails 项目。我需要在不刷新页面的情况下保存订阅者数据!
在代码块“app/views/users/new.html.haml”的最后一行中,我需要将 form.button 更改为一个 ajax 按钮。我在项目中包含了 jQuery。我应该如何编码?回答时请考虑我是初学者!
提前谢谢你!(-_^)
这是路线:
users_new GET /users/new(.:format) users#new
users GET /users/index(.:format) users#index
create POST /users/create(.:format) users#create
这是我的 app/views/users/new.html.haml:
.form1
%h1
Subscriber
=form_for @user, :url => :create do |form|
- unless @user.errors.empty?
- @user.errors.full_messages.each do |message|
.alert.alert-danger
%ul
- @user.errors.full_messages.each do |message|
%li= message
%div
.row.form-group
.col-lg-3
%label
Email:
=form.text_field :email, :class => 'form-control'
.row.form-group
.col-lg-3
%label
Name:
=form.text_field :name, :class => 'form-control'
.row.form-group
.col-lg-3
%label
Phone Number:
=form.text_field :phone_number, :class => 'form-control'
.row.form-group
.col-lg-3
%label
Address:
=form.text_field :address, :class => 'form-control'
%div=form.button 'Save', :class => 'btn btn-primary'
这是 app/controllers/users_controller.rb:
class UsersController < ApplicationController
def index
end
def new
@user = User.new
end
def create
@user = User.new params[:user]
@user.save
redirect_to users_new_path
end
end
