我正在尝试将该字段添加"name"
到设计中,但是当我注册一个新用户时,它会在我推送提交时中断。
我已确保运行rake db:migrate
并重新启动服务器,但出现此错误:
设计中的 ActiveRecord::StatementInvalid::RegistrationsController#create
NoMethodError:nil 的未定义方法“名称”:NilClass:插入“用户”(“created_at”、“current_sign_in_at”、“current_sign_in_ip”、“email”、“encrypted_password”、“last_sign_in_at”、“last_sign_in_ip”、“name”、 “pic_file_name”、“remember_created_at”、“reset_password_sent_at”、“reset_password_token”、“sign_in_count”、“title”、“updated_at”) 值(1 美元、2 美元、3 美元、4 美元、5 美元、6 美元、7 美元、8 美元、9 美元、10 美元, 11 美元、12 美元、13 美元、14 美元、15 美元)返回“id”
