如何填充設計用戶

我想用僞造數據填充數據庫，使用faker和populator gems。使用Devise生成模型用戶。如何填充設計用戶

這是我耙文件

namespace :db do 
    desc "Fill database with sample data" 
    task populate: :environment do 
    [User, Article].each(&:delete_all) 
    password = "password" 

    User.populate 20 do |user| 
     user.name = Faker::Name.name 
     user.email = Faker::Internet.email 
     user.password = password 
     user.password_confirmation = password 
     Article.populate 5 do |article| 
     article.user_id = user.id 
     article.title = Populator.words(1..3).titleize 
     article.content = Populator.sentences(2..10) 
     article.created_at = 2.years.ago..Time.now 
     end 
    end 

    end 
end

當我運行耙分貝：填入引發了以下

有什麼不對？

嘗試刪除'password ='password''並僅使用'user.password ='password''' user.password_confirmation =「密碼」'。 –

我有同樣的問題，但'user.password = password'在控制檯中工作！ – Brary

填充器不會加載ActiveRecord的實例;所以任何驗證，回調，嵌入的方法都不起作用。相反，它會加載自己的Record對象，使用列屬性和純SQL來提高性能。另一方面，Devise不創建：密碼列，它創建encrypted_password列並執行場景後面的所有邏輯，如果您想了解有關代碼的詳細信息，請檢查此link。

解決方法：我們需要調用password_digest來加密給定的密碼，然後直接設置encrypted_password，但是這個method受保護，不能在rake內部調用。相反，我們將使用'new'方法來觸發password_digest，因此您的代碼將如下所示：

password = "password" 

User.populate 20 do |user| 
    user.name = Faker::Name.name 
    user.email = Faker::Internet.email 
    user.encrypted_password = User.new(:password => password).encrypted_password 
    # rest of your code here  
end

感謝您的提示！我使用'password_digest'來使用我自己的基於會話/ cookie的認證，所以對於任何人來說，首先設置'password ='password''像上面那樣，然後設置它，使用'user.password_digest = User.new（：password =>密碼）.password_digest' – Sia

確保您的型號（您的案例中的表格）actually有一個名爲"password"的列。

如果是這樣，那麼，嘗試檢查是否有attr_accessible :password

它有一個列密碼和attr_accessible：密碼在用戶模型 –
