编辑个人资料按钮不起作用

Question

刚开始学习ruby，所以提前抱歉任何愚蠢的错误。无论如何，每当我尝试以“客户”身份登录时，以下是由于客户资料中的“更新”按钮而产生的错误。

cust_profile.rb

class CustProfile < ApplicationRecord
  belongs_to :user
end

user.rb

class User < ApplicationRecord
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  enum role: [:customer, :cook, :admin]
  # after_initialize :set_default_role, :if => :new_record?

  has_attached_file :photo

  validates_attachment_presence :photo
  validates_attachment_size :photo, :less_than => 1.megabytes
  validates_attachment_content_type :photo, :content_type => ['image/jpeg', 'image/png']

  def set_default_role
    self.role ||= :customer
  end

  has_one :cook_profile, required: false
  has_one :cust_profile, required: false

easy_controller.rb

class EasyController < ApplicationController
  def home
    if user_signed_in?
      @user = current_user

      if current_user.cook?
        render :cook_home
      end
      if current_user.customer?
        render :cust_home
      end
      if current_user.admin?
        render :admin_home
      end
    end        
  end

  def profile
    if user_signed_in?
      @user = current_user

      if current_user.cook?
        render :cook_profile
      else if current_user.cust?
    render :cust_profile
    end
    end
  end

  def cust_home
      @user = current_user
      if current_user.cust?
          render :cust_home
      end
  end
end
end

以下是因为我的cust_home.html页面中的“更新”按钮而生成的错误

Easy＃home

中的ActionController :: UrlGenerationError

没有路由匹配{：action =＆gt;“edit”，：controller =＆gt;“cust_profiles”，：id =＆gt; nil}，缺少必需的密钥：[：id]

我怀疑错误来自我的控制器，但无法弄清楚如何继续。

修改

的routes.rb

Rails.application.routes.draw do
  resources :cuisines
  resources :cook_profiles
  resources :cust_profiles
  devise_for :users, :controllers => {:registrations => 'registrations'}
  # For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html

  #----- Home routes
  get 'home', to: 'easy#home', as: 'easy_home'
  get 'cook_home', to: 'easy#cook_home', as: 'cook_home'
  get 'cust_home', to: 'easy#cust_home', as: 'cust_home'
  get 'admin_home', to: 'easy#admin_home', as: 'admin_home'
  root to: 'easy#home'

  #----- Route to user-appropriate profile page
  get '/profile', to: 'easy#profile', as: 'profile'

end

Answer 1

错误不是由Update按钮引起的。它来自：

ActionController::UrlGenerationError in Easy#home 

因此，您必须检查EasyController#home的视图。当您查看它（cust_home.html）时，只有一个地方可能导致此问题：

<%= link_to 'Update',  edit_cust_profile_path(current_user.cust_profile) %>

因为它说：

No route matches {:action=>"edit", :controller=>"cust_profiles", :id=>nil}, missing required keys: [:id]

可能current_user.cust_profile是nil。
