ActiveRecord：：StatementInvalid in Devise：：RegistrationsController#create

Question

我正在尝试为我的Devise User模型添加一些额外的信息，如first_name、last_name、年龄、性别和城市。

当我填写注册表格并单击提交时，我会收到以下错误：

SQLite3::ConstraintExc的：不是NULL约束失败：users.first_name：插入到用户（电子邮件，encrypted_password，created_at，updated_at）值 (?, ?, ?, ?)

def each
  loop do
    val = step
    break self if done?
    yield val
  end

如果有任何用途，以下是参数：

参数：

{"utf8"=

以下是我的schema.rb以防万一：

create_table "users", force: :cascade do |t|
    t.string   "email",                  default: "", null: false
    t.string   "encrypted_password",     default: "", null: false
    t.string   "reset_password_token"
    t.datetime "reset_password_sent_at"
    t.datetime "remember_created_at"
    t.integer  "sign_in_count",          default: 0,  null: false
    t.datetime "current_sign_in_at"
    t.datetime "last_sign_in_at"
    t.string   "current_sign_in_ip"
    t.string   "last_sign_in_ip"
    t.string   "confirmation_token"
    t.datetime "confirmed_at"
    t.datetime "confirmation_sent_at"
    t.string   "unconfirmed_email"
    t.string   "first_name",                          null: false
    t.string   "last_name",                           null: false
    t.integer  "age",                                 null: false
    t.string   "city",                                null: false
    t.string   "gender",                              null: false
    t.datetime "created_at",                          null: false
    t.datetime "updated_at",                          null: false
    t.index ["confirmation_token"], name: "index_users_on_confirmation_token", unique: true
    t.index ["email"], name: "index_users_on_email", unique: true
    t.index ["reset_password_token"], name: "index_users_on_reset_password_token", unique: true
  end

这也是我的user.rb模型：

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

Answer 1

您在电子邮件上有一个唯一的索引。错误的意思是您尝试保存的电子邮件在数据库中不为空。用户已收到此电子邮件。更改电子邮件，它应该可以工作。

  # to check for the user in the database 
  rails c 
  user = User.find_by_email("[e-mail]") should bring back a user. 

Answer 2

要在用户上设置尚未在设计中设置的附加列，我允许以这种方式访问我的Application ationContle ler。铁路4

before_filter :configure_permitted_parameters, if: :devise_controller?

protected

def configure_permitted_parameters
  # Only add some parameters
  devise_parameter_sanitizer.for(:accept_invitation).concat [:first_name, :last_name]
end

或

before_action :configure_permitted_parameters, if: :devise_controller?

protected

def configure_permitted_parameters
  devise_parameter_sanitizer.for(:sign_up) << :full_name
end

这将允许您将名字和姓氏与您设置的其他内容联系在一起。

def configure_permitted_parameters
  additional_params = [:name, :company, :email_confirmation,   {addresses_attributes: [:address1, :address2, :city, :state, :zip, :country, :name]}]
  devise_parameter_sanitizer.permit(:sign_up, keys: additional_params)
  devise_parameter_sanitizer.permit(:account_update, keys: additional_params)
end
