在Django中，如何更改“这个字段是必需的”。“名称是必需的”?

I'm using the forms framework. And when I set required=True, this error shows. What if I don't want it to say "This field", but instead, say the label?

我使用的是表单框架。当我设置required=True时，这个错误就会显示出来。如果我不想让它说“这个字段”，而是说标签呢?

Since i'm not going to be displaying it beneath the form input. I"m going to display all the errors at the top of the page.

因为我不会在表单输入下面显示它。我要把所有的错误都显示在这页的顶端。

An easy way to specify simple "required" validation messages is to pass the field the error_messages argument.

指定简单的“required”验证消息的一种简单方法是传递error_messages参数。

name = forms.CharField(error_messages={'required': 'Your Name is Required'})

Check the docs for which keys can be specified per field: http://docs.djangoproject.com/en/dev/ref/forms/fields/#django.forms.Field.error_messages

检查每个字段可以指定哪些键:http://docs.djangoproject.com/en/dev/forms/fields/fields/# django.forms.Field.error_messages

For anything else, you're going to need real form validation which means you'd be writing error messages anyways!

对于其他任何东西，您都需要真正的表单验证，这意味着无论如何您都要编写错误消息!

If you want to customize the message a little bit more you can also:

如果你想要更多地定制信息，你还可以:

from django.core.exceptions import ValidationError

def my_validator(value):
    if not len(value):
        raise ValidationError('Your error message here!')

Then, in your models.py:

然后,在你的models.py:

from django import forms

class MyForm(forms.Form):
    my_field= forms.CharField(validators=[my_validator])
