如何在 Rails 身份验证管道中为会话点击 'create' 而不是 'new'？

Question

我不知道为什么我的 Rails 身份验证管道只命中 new 而不是 create。这会导致登录页面重新呈现并且永远不会转到 search 页面。你能看看我的代码，看看我可能忽略了什么吗？

我正在使用 bcrypt 来散列 user

中的密码属性

我的routes

Rails.application.routes.draw do
  root :to => "searches#search" 

  resources :users, only: [:show, :new, :create, :destroy]

  get '/login', to: 'sessions#new', as: 'login'
  post '/login', to: 'sessions#create'

  delete '/logout', to: 'sessions#destroy', as: 'logout'

  get 'searches/index' => "searches#index"
  get 'searches/show' => "searches#show"
  get 'searches/search' => "searches#search" 


  get 'audits/show' => 'audits#show'     
  get 'audits/download' => 'downloads#show' 
  post 'audits/' => 'audits#create'

  # For details on the DSL available within this file, see https://guides.rubyonrails.org/routing.html
end

application_controller

class ApplicationController < ActionController::Base
  before_action :authorized #lock down this whole app
  helper_method :current_user #i can call current_user from a view

  def current_user
    User.find_by({ id: session[:user_id] })
  end

  def logged_in?
    !!current_user
  end

  def authorized
    redirect_to login_path unless logged_in?
  end

end

sessions_controller

class SessionsController < ApplicationController
  skip_before_action :authorized, only: [:new, :create]

  def new
  end

  def create
    #handles the POST request to /login
    @user = User.find_by(username: params[:username])
    if @user && @user.authenticate(params[:password])
      session[:user_id] = @user.id
      redirect_to @user
    else
      flash[:notice] = 'Invalid username or password'
      redirect_to login_path
    end
  end

  def destroy
    session.delete(:user_id)
    flash[:notice] = 'logged out'
    redirect_to login_path
  end

end

和 sessions/new.html.erb

中的登录表单


<div class='login'>
    <div class="login-form">
        <form>
            <div class="form-group">
                <%= form_with url: login_path, method: 'post', local: true do |f|  %>
                    <%= f.label :username,  "Username", class: "col-md-4 control-label" %>
                    <%= f.text_field :username, class: "form-control", required: true %>
                    <%= f.label :password,  "Password", class: "col-md-4 control-label" %>
                    <%= f.password_field :password, class: "form-control", required: true %>
                    <%= f.submit "Login", class: "btn btn-default btn-primary" %>
                <% end %>
            </div>

        </form>
    </div>
</div>

我也试过 form_tag 但同样的问题。我将方法明确化只是为了确定，即使它不是必需的。

你可以把routes.rb改成：

Rails.application.routes.draw do
  # codes
  resources :sessions, only: [:create]
  get '/login', to: 'sessions#new', as: 'login'
  delete '/logout', to: 'sessions#destroy', as: 'logout'
  # codes
end

并将表单标签更改为

<%= form_with url: sessions_path, method: 'post', local: true do |f| %>

谢谢。

Answer 2

所以问题是我的 form_with 在 Bootstrap <form> 标签中。默认情况下，表单为 get。
