我怀疑类UserForm应该是模型形式。您可能想要更改字段，但它应该从 `ModelForm.

所以将表单定义更改为

class UserForm(forms.ModelForm):
   class Meta:
       model = User
       fields = [...] # list of fields you want from model

   #or define fields that you want.
   ....

我错误地覆盖了 __init__() 方法，没有初始参数，如下所示

class MyForm(forms.ModelForm):
    ...
    def __init__(self):
        super(CaseForm, self).__init__()
        ...

结果得到这个错误

/case/create 处的类型错误

__init__() 得到了一个意外的关键字参数“initial”

为了修复它，我将参数设置为 __init__() 并在调用超类 __init__() 时传递它们，请参见下面的结果

class MyForm(forms.ModelForm):
    ...
    def __init__(self, *args, **kwargs):
        super(CaseForm, self).__init__(*args, **kwargs)
        ...

forms.py 在方括号中定义字段，例如 fields=['field 1', 'field 2',...]

class CustomerForm(forms.ModelForm):        
    class Meta:
        model = Customer
        fields = ['fname','lname','email','address','city','state','zip','username','password','age','mobile','phone']

我解决了尝试将表单保存到数据库时遇到的类似错误。“Report() 得到了一个意外的关键字参数‘摘要’”

问题是 models.py 和 forms.py 中的字段名称不匹配。

在models.py 的类Report 中，该字段的名称是“summary_input”，但在forms.py 中它被命名为“summary”，所以我更改了forms 中的变量名以匹配models 中的变量名。

# models.py
class Report(models.Model):
    summary_input = models.TextField()

# forms.py
class ReportForm(forms.Form):
    summary = forms.CharField(widget=forms.widgets.Textarea)
    # changed to 
    # summary_input = forms.CharField(widget=forms.widgets.Textarea)
