Ruby on Rails POST请求失败

Question

Here the thing goes, I wanna write a login in a page in Ruby on Rails, when the url is localhost:3000/admin , I'll get the page which need to fill in. After the form has filled in, I submit the button and the form should be admitted to the create action with post method, however it still works with get method and new action.

What happens to it?

Here is the routes.rb file:

     Prefix Verb          URI Pattern                Controller#Action
new_admin_users GET      /admin/users/new(.:format)  admin/users#new
   admin_users  POST     /admin/users(.:format)      admin/users#create
         admin  GET      /admin(.:format)            admin/users#new
                POST     /admin(.:format)            admin/users#create
    posts_home  GET      /posts/home(.:format)       redirect(301, /posts)
   posts_about  GET      /posts/about(.:format)      redirect(301, /about)

Then here is the new action

  <form class="form-signin">
    <h2 class="form-signin-heading">Please sign in</h2>
    <%= form_for :user,url:admin_users_path do |f| %>
      <p>
        <%= f.label :name%><br>
        <%= f.text_field :name ,class:"form-control" %>
      </p>
      <p>
        <%= f.label :pass%><br>
        <%= f.text_field :pass,class:"form-control" %>
      </p>
      <div class="checkbox">
        <label>
          <input type="checkbox" value="remember-me"> Remember me
        </label>
      </div>
      <p>
        <%= f.submit'Sign in', :class=>"btn btn-lg btn-primary btn-block" %>
      </p>
      <%= link_to 'Back', posts_path %>
    <%end%>
  </form>

Here is the routes.rb :

   Rails.application.routes.draw do
     namespace :admin do
       resources :users
       get "",  to:"users#new"
       post "", to:"users#create"
     end
     get "/posts/home",  to: redirect("/posts")
     get "/posts/about", to: redirect("/about")
     resources :posts do
       resources :comments
     end
     root "posts#index"
     get "/home",to: "posts#index"
     get "/about",to: "posts#about"
   end

If you have some throught, please tell me, thanks in advance!

Answer 1

You must have the actual User object built inside your controller. Try using that inside your form instead of symbol :user .

<%= form_for @user, url: admin_users_path do |f| %>
...

Answer 2

You can try explicitly specifying the method post Instead of

<%= form_for :user,url:admin_users_path do |f| %>

Use this:

 <%= form_for :user,url:admin_users_path, method: :post do |f| %>

Also check the created action in form created such way

Hope this Helps
