的db / schema.rb（uupdate）

Question

之前我确实创建了一个名为address的属性。但我没有在注册表单中使用它。当我在注册表单中输入所有文本字段时，它会闪烁错误

表单包含1个错误。

地址不能为空

我应该检查的其他地方？

控制器

 def new
        @tutor = Tutor.new
      end
      def create
        @tutor = Tutor.new(tutor_params)
        if @tutor.save
          log_in @tutor
          flash[:success] = "Congratulations! Your registration is successful!"
          redirect_to @tutor
        else
          render 'tutors/new'
        end
      end
    # Handle sign-up failure, to redirect the tutor to the registeration form again
      def tutor_params
        params.require(:tutor).permit(:name, :email, :password, :password_confirmation,:gender 
          ,:education_level,:institution,:exprience,:district,:subject,:student_level)
      end

end
`

Answer 1

def create
        @tutor = Tutor.new(tutor_params)
        if @tutor.save
          log_in @tutor
          flash[:success] = "Congratulations! Your registration is successful!"
          redirect_to @tutor
        else
          flash[:tutor] = @tutor
          redirect_to new_tutor_path
        end
      end

还要确保您的导师模型中的validates_presence_of：地址。

Answer 2

更改

validates :address, presence: true, length: {maximum: 100}

到

validates :address, length: {maximum: 100}

在您的模型中tutor.rb

您在创建导师时验证模型中是否存在地址字段，但您没有传递地址参数。

如果要从db中删除现有地址字段，在您的终端中，执行

rails g migration remove_address_from_tutors

在新创建的迁移文件中添加以下代码

class RemoveAddressFromTutors < ActiveRecord::Migration
  def change
    remove_column :tutors, :address
  end
end

然后在终端中执行rake db:migrate
