在Rails中删除用户的帐户

我有删除用户帐户的问题.这是我收到的错误:

undefined method `user_path' for #<#:0x00000005358f68>

我正在使用Devise + omniauth,所以对于像我这样的初学者来说,我的路由看起来有点复杂.

Rails.application.routes.draw do

  devise_for :users, :controllers => { omniauth_callbacks: 'omniauth_callbacks' }
  match '/users/:id/finish_signup' => 'users#finish_signup', via: [:get, :patch], :as => :finish_signup
  match 'users/:id' => 'users#show', via: :get
  match 'users' => 'users#index', via: :get
  root to: 'static_pages#about'

  get 'static_pages/help'

  resources :categories do
    resources :games, shallow: true
  end

  resources :games, only: [:show, :edit, :update, :destroy] do
    resources :comments
  end

end

"rake routes"输出:

                         DELETE    /users(.:format)                             devise/registrations#destroy
           finish_signup GET|PATCH /users/:id/finish_signup(.:format)           users#finish_signup
                         GET       /users/:id(.:format)                         users#show
                   users GET       /users(.:format)                             users#index

用户控制器:

class UsersController < ApplicationController
  before_action :set_user, only: [:show, :edit, :update, :destroy, :finish_signup]

  def index
    @users = User.all
  end

  # GET /users/:id.:format
  def show
    @user = User.find(params[:id])
  end

  # GET /users/:id/edit
  def edit
    # authorize! :update, @user
  end

  # PATCH/PUT /users/:id.:format
  def update
    # authorize! :update, @user
    respond_to do |format|
      if @user.update(user_params)
        sign_in(@user == current_user ? @user : current_user, :bypass => true)
        format.html { redirect_to @user, notice: 'Your profile was successfully updated.' }
        format.json { head :no_content }
      else
        format.html { render action: 'edit' }
        format.json { render json: @user.errors, status: :unprocessable_entity }
      end
    end
  end

  # GET/PATCH /users/:id/finish_signup
  def finish_signup
    # authorize! :update, @user
    if request.patch? && params[:user] #&& params[:user][:email]
      if @user.update(user_params)
        # @user.skip_reconfirmation!
        sign_in(@user, :bypass => true)
        redirect_to root_url, notice: 'Your profile was successfully updated.'
      else
        @show_errors = true
      end
    end
  end

  # DELETE /users/:id.:format
  def destroy
    # authorize! :delete, @user
    @user.destroy
    respond_to do |format|
      format.html { redirect_to root_url }
      format.json { head :no_content }
    end
  end

  private
    def set_user
      @user = User.find(params[:id])
    end

    def user_params
      accessible = [ :name, :email ] # extend with your own params
      accessible << [ :password, :password_confirmation ] unless params[:user][:password].blank?
      params.require(:user).permit(accessible)
    end
end

我不知道为什么"users_path"没有像往常一样工作,所以我把这行添加到routes.rb:

我试过通过routes.rb中的这一行删除用户的帐户来解决我的问题,但是这没有用.

match 'users/id:' => 'users#destroy', via: :delete

这是我删除用户帐户的按钮:

= link_to 'Delete user', user, method: :delete, data: { confirm: "You sure?" }, class: "btn btn-danger btn-sm"

用户没有"@"符号,因为它处于迭代循环中.

删除这两行

  match 'users/:id' => 'users#show', via: :get
  match 'users' => 'users#index', via: :get

并用......替换它们

  resources :users, only: [:index, :show, :destroy]

这将为您提供用户所需的三条路线.
