使用ACCOUNT_FORMS覆蓋Django allauth登錄表單

Question

我已使用簡單設置變量ACCOUNT_SIGNUP_FORM_CLASS覆蓋註冊表單，但覆蓋登錄表單，您需要使用ACCOUNT_FORMS = {'login': 'yourapp.forms.LoginForm'}。我有我想要的形式，並將其與脆皮形式和Bootstrap3完美顯示：

class LoginForm(forms.Form): 
    login = forms.EmailField(required = True) 
    password = forms.CharField(widget = forms.PasswordInput, required = True) 

    helper = FormHelper() 
    helper.form_show_labels = False 
    helper.layout = Layout(
     Field('login', placeholder = 'Email address'), 
     Field('password', placeholder = 'Password'), 
     FormActions(
      Submit('submit', 'Log me in to Cornell Forum', css_class = 'btn-primary') 
     ), 
    ) 

當我提交表單，我得到AttributeError at /account/login/ - 'LoginForm' object has no attribute 'login'。這裏有什麼問題？原來allauth登錄表格的源代碼在這裏：https://github.com/pennersr/django-allauth/blob/master/allauth/account/forms.py

根據我的理解，您可以使用ACCOUNT_FORMS來覆蓋默認的LoginForm，但您需要提供一個包含原始類中提供的所有方法的類。你的班級缺少login方法。

我會在您的settings.py文件中設置ACCOUNT_FORMS = {'login': 'yourapp.forms.YourLoginForm'}，其中YourLoginForm繼承自原始類。

# yourapp/forms.py 

from allauth.account.forms import LoginForm 

class YourLoginForm(LoginForm): 
    def __init__(self, *args, **kwargs): 
     super(YourLoginForm, self).__init__(*args, **kwargs) 
     self.fields['password'].widget = forms.PasswordInput() 

     # You don't want the `remember` field? 
     if 'remember' in self.fields.keys(): 
      del self.fields['remember'] 

     helper = FormHelper() 
     helper.form_show_labels = False 
     helper.layout = Layout(
      Field('login', placeholder = 'Email address'), 
      Field('password', placeholder = 'Password'), 
      FormActions(
       Submit('submit', 'Log me in to Cornell Forum', css_class = 'btn-primary') 
      ), 
     ) 
     self.helper = helper
