Django的添加（）到底需要2個參數（3給出）

    # Examples:

    url(r'^users/add', addx), 
    url(r'^TESTAPI/resetFixture', TESTAPI_resetFixturex) 
    #url(r'^TESTAPI/unitTests', unitTests) 
) 

我看過了類似的問題之前在stackoverflow上問過，但他們的解決方案無法幫助我並導致我遇到其他錯誤。所以是啊，我不明白如何才能給3個參數添加，當我只把用戶和密碼作爲我的論點在視圖中。有人能幫我嗎。順便說一句，我只測試添加功能現在在視圖中使用：

curl -H「Content-Type：application/json」-H「Accept：application/json」-X POST -d'{「user」 「test」，「password」：「test」}'localhost：8000/users/add -o test.html

Answer 1

將實例（通常由self引用）傳遞給類的每個實例方法。 This question解釋更多關於什麼是自我和代表。另外還有大量高質量的oop python教程。

我假設add是UsersModel方法，在這種情況下

你的函數定義應該像（如果是請正確縮進，因爲它的問題immensely`）：

def add(self, user1, password1):

另外，我認爲這會對django教程有很大的幫助。 Django創建了一個ORM，允許您在不寫任何sql的情況下與數據庫進行交互！:)它非常易於使用。此外，django還內置User模型，該模型提供開箱驗證和用戶創建
