由於未定義的方法'encrypted_pa​​ssword ='，用戶

Question

Travis的Rails構建失敗所以我有一個使用Devise gem的用戶模型。

# == Schema Information 
# 
# Table name: USERS 
# 
# u_id     :integer   not null, primary key 
# email     :string(255)  default(""), not null 
# encrypted_password  :string(255)  default(""), not null 
# reset_password_token :string(255) 
# reset_password_sent_at :datetime 
# remember_created_at :datetime 
# sign_in_count   :integer   default(0), not null 
# current_sign_in_at  :datetime 
# last_sign_in_at  :datetime 
# current_sign_in_ip  :string(255) 
# last_sign_in_ip  :string(255) 
# join_date    :datetime 
# organization   :string(255) 
# created_at    :datetime 
# updated_at    :datetime 
# 

class User < ActiveRecord::Base 
    # Include default devise modules. Others available are: 
    # :confirmable, :lockable, :timeoutable and :omniauthable 
    devise :database_authenticatable, :registerable, 
     :recoverable, :rememberable, :trackable, :validatable 
    self.table_name = "USERS" 
end 

我也有一個工廠女孩工廠來創建用戶對象爲我的RSpec的測試

FactoryGirl.define do 
    factory :user do |user| 
    user.email 'test@example.com' 
    user.password Devise.friendly_token[0,20] 
    end 
end 

所有我對我的本地環境的測試與rake spec通，但是當我運行特拉維斯打造，它始終未能在RSpec的測試用：

undefined method `encrypted_password=' for #<User:0x67c24931> 
# ./spec/models/user_spec.rb:26:in `(root)' 

這裏是我的user_spec.rb

require 'rails_helper' 

RSpec.describe User, :type => :model do 
    it "successfully creates a user" do 
    @user = FactoryGirl.create :user 
    expect(@user.save).to be_truthy 
    end 
end 

我通過rails c檢查了User.new.respond_to?(:encrypted_password=)返回true。我不確定什麼可能是錯誤的，我找不到我的問題的任何答案。那麼，我錯過了什麼嗎？

我也在運行0123之前嘗試運行在travis上，它顯示用戶表具有encrypted_pa​​ssword列。我也運行了cat db/schema.rb以查看遷移是否完全發生，並且encrypted_pa​​ssword也在那裏。現在我不確定這個字段在數據庫中會出現什麼問題。

Answer 1

那麼，當我在MySQL中創建我的表時，我對所有表名使用了大寫字母。出於某種原因，在本地運行時，表名在開發模式下仍爲大寫，但在測試模式下爲小寫。所以，在我的用戶模型中，我只是將self.table_name = "USERS"更改爲self.table_name = "users"，並解決了我的問題。
