Django的ModelForm中的`fields`属性用于指定表单中包含哪些字段。你在`EmergencyForm`中使用了`fields = '__all__'`,这意味着表单中应该包含模型`Emergency`中的所有字段。但是,你在错误提示中看到的`FieldError`提示表明,在`Emergency`模型中不存在名为`__all__`的字段。
如果你想在表单中包含模型中的所有字段,可以将`fields`属性设置为`None`,如下所示:
```python
class EmergencyForm(forms.ModelForm):
""" 紧急联系人ModelForm """
class Meta:
model = models.Emergency
fields = None
```
这样,表单将包含模型中的所有字段。
如果你只想在表单中包含部分字段,可以将`fields`属性设置为一个包含需要包含的字段名称的列表,如下所示:
```python
class EmergencyForm(forms.ModelForm):
""" 紧急联系人ModelForm """
class Meta:
model = models.Emergency
fields = ['name', 'phone', 'relation']
```
在上面的示例代码中,我们指定了表单中需要包含的字段名称。

这段代码是写在class StaffModelForm(forms.ModelForm):里面吗
是的,这段代码应该写在 `StaffModelForm` 类中的 `clean_tel` 方法中,如下所示:
```python
class StaffModelForm(forms.ModelForm):
"""
员工信息ModelForm
"""
class Meta:
model = models.StaffInfo
fields = [
"POST", "NAME", "BIRTH", "SEX", "HEIGHT", "ORIGIN", "NATION",
"TEL", "RES_ID", "SCHOOL", "MAJOR", "EDU_LEVEL",
"REGISTERED_PLACE", "WECHAT", "ADDRESS", "EMAIL", "MARRIAGE"
]
def clean_tel(self):
tel = self.cleaned_data.get('TEL')
if tel and (not tel.isdigit() or len(tel) != 13):
raise forms.ValidationError('电话号码必须是13位的数字')
return tel
```
在这个代码中,我们将 `clean_tel` 方法定义在了 `StaffModelForm` 类中,并在 `Meta` 类中指定了模型和字段列表。`clean_tel` 方法会在表单数据验证时被自动调用,用于检查 `TEL` 参数是否符合要求。如果不符合要求,就会抛出 `ValidationError` 异常,阻止表单数据的提交。
class StaffModelForm(forms.ModelForm): """ 员工信息ModelForm """ class Meta: model = models.StaffInfo fields = ["POST", "NAME", "BIRTH", "SEX", "HEIGHT", "ORIGIN", "NATION","TEL","RES_ID","SCHOOL","MAJOR","EDU_LEVEL", "REGISTERED_PLACE","WECHAT","ADDRESS","EMAIL","MARRIAGE"]怎么在这段modelform中添加数据验证,比如说对EMAIL要求必须包涵@和.com项
你可以在`StaffModelForm`中对`EMAIL`字段进行自定义验证,例如:
```python
class StaffModelForm(forms.ModelForm):
""" 员工信息ModelForm """
class Meta:
model = models.StaffInfo
fields = ["POST", "NAME", "BIRTH", "SEX", "HEIGHT", "ORIGIN",
"NATION","TEL","RES_ID","SCHOOL","MAJOR","EDU_LEVEL",
"REGISTERED_PLACE","WECHAT","ADDRESS","EMAIL","MARRIAGE"]
def clean_email(self):
email = self.cleaned_data.get("EMAIL")
if "@" not in email or ".com" not in email:
raise forms.ValidationError("邮箱格式不正确")
return email
```
在这个例子中,我们定义了一个名为`clean_email`的方法来对`EMAIL`字段进行验证。通过`cleaned_data`方法获取到的`email`数据,我们可以进行自定义的验证,如果验证不通过,我们可以使用`ValidationError`来抛出错误信息。当`clean_email`方法中的所有验证都通过后,我们将会返回验证通过的`email`数据。这样,当表单提交时,如果`EMAIL`字段的格式不正确,将会抛出错误信息,而不会进行提交。
