/Test/ 'tuple' 處的 AttributeError object 沒有屬性 'get'

Question

當我嘗試打開 django crispy-reports 表單時，我目前看到以下錯誤。 Í 可以在網上找到的所有信息都是，我可能在不應該是逗號的地方添加了一個逗號。 但是我真的找不到。

我的播放列表表格 class

from django import forms
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Submit

class PlaylistForm(forms.Form):
    name = forms.CharField(
        label='Name', 
        max_length= 64, 
        required = True)

    comment = forms.CharField(
        label='Kommentar',
        max_length= 256,
        required = False)

    def __init__(self, *args, **kwargs):
        super().__init__(args, kwargs)
        self.helper = FormHelper()
        self.helper.form_id = 'id_playlist_form'
        self.helper.form_class = 'forms'
        self.helper.form_method = 'post'
        self.helper.form_action = 'test'

        self.helper.add_input(Submit('submit', 'Absenden'))

edit.html 模板

{% load crispy_forms_tags %}
{% crispy playlist_form playlist_form.helper %}

urlpatterns 條目

我找到了解決方案。 就我而言，這是一個錯誤的超級電話

如何不去做

    def __init__(self, *args, **kwargs):
        super().__init__(args, kwargs)

怎么做

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
