セロリ：フォームは（何のLENを持っていない）

Question

私はPythonのバージョンとセロリのバージョンを更新した、と今では提出フォームからタスクを作成することはできません。

• のPython == 3.4。
• ジャンゴ== 1.10.3
• セロリ== 4.0.0

マイビュー：

class SignupBase(FormView): 

    def get_form_class(self, **kwargs):   
     return SignupFormBase 


    def form_valid(self, form): 

     user = User(username=generate_random_username()) 
     user.save() 

     signuptask = signup_user.delay(username=user.username,form=form)

を何か新しいものがあります私が逃したセロリー？セロリのビートで動作する他のタスクは正常に動作していますが、この1つのタスクは正しくありません。

このメソッドは、この

class SignupFormBaseWithLen(SignupFormBase): 
    def __len__(self): 
     return 10 #here you have to set which len you should pass 

を試してみて、あなたがそのフォームに `__len__`メソッドを追加し

class SignupBase(FormView): 

    def get_form_class(self, **kwargs):   
     return SignupFormBaseWithLen
