Django -如何按名称验证数据

from django.db import models

class User(models.Model):
    name = models.CharField(max_length=100)

from django import forms

class UserForm(forms.Form):
    name = forms.CharField(max_length=100, label='Name')

    def clean_name(self):
        name = self.cleaned_data['name']
        # 进行名称验证的逻辑判断
        if name != 'admin':
            raise forms.ValidationError('Invalid name')
        return name

from django.shortcuts import render
from .forms import UserForm

def validate_name(request):
    if request.method == 'POST':
        form = UserForm(request.POST)
        if form.is_valid():
            # 数据验证通过，进行后续处理
            name = form.cleaned_data['name']
            return render(request, 'success.html', {'name': name})
    else:
        form = UserForm()
    return render(request, 'validate_name.html', {'form': form})

<form method="post">
  {% csrf_token %}
  {{ form.as_p }}
  <button type="submit">Submit</button>
</form>

<p>Success! The name is {{ name }}.</p>
