ruby-on-rails - ActiveRecord::RecordInvalid 验证失败:帐户必须存在

Question

使用 ruby​​ 2.6 和rails 5.2 Rails 控制台中的用户创建引发

ActiveRecord::RecordInvalid (Validation failed: Account must exist)

我刚刚生成了 Devise User，所以暂时没有 user_controller

型号

用户.rb

class User < ApplicationRecord
   belongs_to :account
end

账户.rb

class Account < ApplicationRecord
    has_many :users
end

Controller

accounts_controller.rb

class AccountsController < ApplicationContoller
     def new                     
       redirect_to root_path       
       unless current_user.account.nil?
       @account = Account.new       
    end
     def create                   
      @account = Account.new(account_params)          
      if @account.save            
      current_user.account = @account                     
      current_user.save
      redirect_to root_path, success: "Your account has been created!"               
  else                         
      render :new                  
    end                        
  end
........
end

对于 Rails 5，默认情况下需要 belongs_to 关联。因此您应该将该帐户设置为可选。

belongs_to :account, optional: true
