Django 模型形式

Question

我有一个非常简单的模型形式，但由于某种原因，代码无法同步数据库并抛出错误： AttributeError: 'module' object has no attribute 'CharField'

代码如下（在我的 models.py 中）：

from django.db import models
from django.forms import ModelForm, Textarea, forms
from django.forms.fields import DateField, ChoiceField, MultipleChoiceField

class SubmitJobDTP(models.Model):
    SERVICE_CHOICES = (
        ('blog', (
            ('DTP1', 'cccccccccccccccccc: GBP 65.00'),
            ('DTP2', 'vvvvvvvvvvvvvvvvvv: GBP 110.00'),
            ('DTP3', 'bbbbbbbbbbbbbbbbbb: GBP 175.00'))
        )
    )
    package = models.CharField(max_length=5, choices=SERVICE_CHOICES)
    firstname = models.CharField(max_length=25)
    lastname = models.CharField(max_length=25)
    contact_number = models.CharField(max_length=25)
    email_address = models.EmailField()    
    attachment_1 = models.FileField(upload_to='uploadir')
    attachment_2 = models.FileField(upload_to='uploadir')
    attachment_3 = models.FileField(upload_to='uploadir')
    attachment_4 = models.FileField(upload_to='uploadir')
    attachment_5 = models.FileField(upload_to='uploadir')
    comments = models.CharField(max_length=150)

class SubmitJobForm(ModelForm): 
    attachment_1 = forms.FileField(label='Attach file 1',required=False)
    attachment_2 = forms.FileField(label='Attach file 2',required=False)
    attachment_3 = forms.FileField(label='Attach file 3',required=False)
    attachment_4 = forms.FileField(label='Attach file 4',required=False)
    attachment_5 = forms.FileField(label='Attach file 5',required=False)
    package = forms.CharField(required=False)
    firstname = forms.CharField(required=False)
    lastname = forms.CharField(required=False)
    contact_number = forms.IntegerField(required=False)
    email_address = forms.EmailField(required=False)

    class Meta:
        model = SubmitJobDTP
        fields = ('package', 'first name', 'last name', 'contact_number',
            'email_address', 'comments', 'attachment_1', 'attachment_2',
            'attachment_3', 'attachment_4', 'attachment_5')

我想知道问题出在哪里是：模型表单同步数据库中的 FileField 正确，但其他字段：CharField、IntegerField 和 EmailField 似乎不起作用。我已阅读模型表单上的 django 文档，但似乎找不到与此错误特别相关的任何内容。

任何建议将不胜感激。

Answer 1

您实际上并未导入表单模块。

>>> from django.forms import forms
>>> forms.CharField
Traceback (most recent call last):
  File "<console>", line 1, in <module>
AttributeError: 'module' object has no attribute 'CharField'
>>> from django import forms
>>> forms.CharField
<class 'django.forms.fields.CharField'>

因此，您希望将导入更改为以下内容：

from django import forms

然后引用 ModelForm：

class SubmitJobForm(forms.ModelForm):

Answer 2

您可以在 forms.py 顶部使用

from django.forms import forms
而不是使用这个
从 django 导入表单
