Question

我刚刚将联系表单添加到我的应用程序中，然后在提交表单时返回了此表单。我的代码上没有blog_quotes，并且在进行迁移时，没有任何变化。

这是我的表格。py

from django import forms
from django.forms import ModelForm
from .models import Contact

class ContactForm(ModelForm):
    required_css_class = 'required'

    class Meta:
        model = Contact
        fields = [
            'name', 'email', 'description',
        ]

我的models.py

class Contact(models.Model):
    name = models.CharField(max_length=100)
    email = models.EmailField()
    description = models.TextField()

    def __str__(self):
        return str(self.id)

    class Meta:
        verbose_name = "contact"
        verbose_name_plural = "contacts"

我想念什么？

如果这是一个开始的项目，则可以尝试将所有迁移重置为零，删除迁移文件，重新创建并重新运行它们。

/ contact /中的ProgrammingError是什么意思？
