django 上的 CharField 輸出為 (<django.forms.fields.CharField object at XXXX> ,)

Question

我想在模板上輸出輸入字段，但輸出為

XXXX 處的 django.forms.fields.CharField 對象

我該如何解決這個問題？ 我嘗試了很多方法來修復它。 但我無法解決這些問題。

Answer 1

模型中的字段后出現昏迷問題，只需將其刪除即可。

所有代碼如a = 1, python 表示為a = (1,)

Answer 2

只需從 forms.py 文件中刪除 (,) 就無需在兩個字段之間給出 ,

表格.py

class Page1(forms.Form):
    user_sir_name = forms.CharField(
        label='姓',
        max_length=20,
        required=True,
        widget=forms.TextInput(),
    )
    user_given_name = forms.CharField(
        label='名',
        max_length=20,
        required=True,
        widget=forms.TextInput(),
    )
    user_sex = forms.ChoiceField(
        label='性別',
        widget=forms.Select,
        choices=EMPTY_CHOICES + GENDER_CHOICES,
        required=True,
    )
