Question

我刚刚设置了django-tinymce并对我的表单进行了一些更改。但是，现在我的表单不再输出正确的错误消息。

我的表格：

TITLE_LENGTH_ERROR = "This title is too long, please make it 200 characters or less."
TITLE_EMPTY_ERROR = "You’ll have to add a title."
TEXT_EMPTY_ERROR = "Please enter some text."
NO_CATEGORY_ERROR = "Please select a category."
NO_CITY_ERROR = "Please select a city."


class ArticleForm(ModelForm):
    text = forms.CharField(widget=TinyMCE(attrs={'cols': 80, 'rows': 30}))
    class Meta:
        model = Article
        fields = ['title', 'text', 'categories', 'city']
        widgets = {'title': forms.TextInput(attrs={
            'placeholder': 'Enter a descriptive title'}),
            'categories': forms.CheckboxSelectMultiple(choices=Category.CATEGORY_CHOICES),
            'city': forms.RadioSelect(choices=City.CITY_CHOICES),
        }
        error_messages = {
            'title': {
                'max_length': TITLE_LENGTH_ERROR,
                'required': TITLE_EMPTY_ERROR,
            },
            'text': {
                'required': TEXT_EMPTY_ERROR,
            },
            'categories': {
                'required': NO_CATEGORY_ERROR,
            },
            'city': {
                'required': NO_CITY_ERROR,
            }
        }

测试：

from articles.models import Article, Category, City
from articles.forms import (
    ArticleForm,
    TITLE_LENGTH_ERROR,
    TITLE_EMPTY_ERROR,
    TEXT_EMPTY_ERROR,
    NO_CATEGORY_ERROR,
    NO_CITY_ERROR,
)


class ArticleFormTest(TestCase):

    def setUp(self):
        self.user = User.objects.create(username='testuser')
        self.user.set_password('12345')
        self.user.save()
        self.client.login(username='testuser', password='12345')

    def test_form_validation_for_blank_inputs(self):
        form = ArticleForm(data={'title': '', 'text': '', 'categories': '', 'city': '', 'author': self.user})
        self.assertFalse(form.is_valid())

        self.assertEqual(
            form.errors['text'],
            [TEXT_EMPTY_ERROR]
        )

如何让表单输出正确的错误消息？此外，是否可以以与其他小部件相同的方式声明tinymce小部件？

好了这么多解释和几个链接可能有助于阐明这一点。在官方的Django文档（https://docs.djangoproject.com/en/1.10/ref/forms/fields/）中，有一个使用表单字段验证和自定义错误消息的示例。必须在您希望与之关联的错误消息的字段中定义error_messages：

text = forms.CharField(widget=TinyMCE(attrs={'cols': 80, 'rows': 30}), error_messages = { 'required': TEXT_EMPTY_ERROR})

话虽这么说，另一个Django文档（https://docs.djangoproject.com/en/1.10/topics/forms/modelforms/）显示在Meta类中为Model表单创建自定义error_messages。由于第一行的工作非常好，但我认为如果您想以最初发布的方式创建错误消息，可以尝试按照文档进行操作。在文档中的＆＃34; Overriding Default Fields部分下，他们展示了一个与您正在做的非常类似的示例，这样可以让您了解可能出现的问题。我相信它是使用这些[]代替这些()来组合您的字段然后不会覆盖Meta类本身中的字段的组合。希望这能让我们对Django有所了解并进行测试!!
