【问题描述】:
我对 Rails 完全陌生,我几乎不知道自己在做什么。但。问题是:使用 Devise 注册新用户会导致:
SQLite3::ConstraintException: column email is not unique:
INSERT INTO "users" ("created_at","encrypted_password", "name", "updated_at")
VALUES (?, ?, ?, ?)
以及请求参数:
{"utf8"=>"✓",
"authenticity_token"=>"1bgk4ovS3JitphVkIvcCZi3ex8QsBq4eEf6ZihQLiHg=",
"user"=>{"name"=>"Someone",
"email"=>"8@prosto.me",
"password"=>"[FILTERED]"},
"commit"=>"Sign up"}
用户模型:
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :token_authenticatable, :confirmable,
# :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable;
end
数据库迁移:
class DeviseCreateUsers < ActiveRecord::Migration
def self.up
change_table(:users) do |t|
## Database authenticatable
t.string :email, :null => false, :default => ""
t.string :name, :null => false, :default => ""
t.string :encrypted_password, :null => false, :default => ""
## Recoverable
t.string :reset_password_token
t.datetime :reset_password_sent_at
## Rememberable
t.datetime :remember_created_at
## Trackable
t.integer :sign_in_count, :default => 0
t.datetime :current_sign_in_at
t.datetime :last_sign_in_at
t.string :current_sign_in_ip
t.string :last_sign_in_ip
## Confirmable
# t.string :confirmation_token
# t.datetime :confirmed_at
# t.datetime :confirmation_sent_at
# t.string :unconfirmed_email # Only if using reconfirmable
## Lockable
# t.integer :failed_attempts, :default => 0 # Only if lock strategy is :failed_attempts
# t.string :unlock_token # Only if unlock strategy is :email or :both
# t.datetime :locked_at
## Token authenticatable
# t.string :authentication_token
# Uncomment below if timestamps were not included in your original model.
# t.timestamps
end
add_index :users, :email, :unique => true
add_index :users, :name, :unique => true
add_index :users, :reset_password_token, :unique => true
# add_index :users, :confirmation_token, :unique => true
# add_index :users, :unlock_token, :unique => true
# add_index :users, :authentication_token, :unique => true
end
def self.down
# By default, we don't want to make any assumption about how to roll back a migration when your
# model already existed. Please edit below which fields you would like to remove in this migration.
end
end
如果我需要提供任何其他代码,请告诉我。 并提前感谢您的所有帮助。
更新数据库架构:
ActiveRecord::Schema.define(version: 20131012114812) do
create_table "users", force: true 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.datetime "created_at"
t.datetime "updated_at"
t.string "name"
end
add_index "users", ["email"], name: "index_users_on_email", unique: true
add_index "users", ["reset_password_token"], name: "index_users_on_reset_password_token", unique: true
end
Update 2:而且身份验证也有问题。设计告诉任何以前成功注册的用户尝试登录的“无效的电子邮件或密码”。
【问题讨论】:
-
看起来你也有同样的问题:stackoverflow.com/questions/5769758/…
-
嗯。尝试drop 用户表。这是您应该不做的事情,但它可能对您有所帮助。
-
@Dave Devise 在安装后完美运行。所以我相信情况并非如此。
-
好的,如果我删除用户表——然后呢?
-
您是否尝试过使用另一封电子邮件,该电子邮件可能不仅仅是一个数字作为前缀?这可能是一个可能的原因
