在默认弹出窗口中设置Django 3 ModelForm中的自定义错误消息

from django import forms
from .models import YourModel

class YourModelForm(forms.ModelForm):
    class Meta:
        model = YourModel
        fields = ['name', 'other_field']  # 根据实际情况指定需要的字段

    error_messages = {
        'name': {
            'required': '自定义错误消息1',
            'invalid': '自定义错误消息2',
            # 其他错误消息...
        },
        # 其他字段的错误消息...
    }

from django.shortcuts import render
from .forms import YourModelForm

def your_view(request):
    if request.method == 'POST':
        form = YourModelForm(request.POST)
        if form.is_valid():
            # 处理有效的表单数据
            # ...
        else:
            # 表单数据无效，重新渲染表单页面并显示错误消息
            return render(request, 'your_template.html', {'form': form})
    else:
        form = YourModelForm()
    
    return render(request, 'your_template.html', {'form': form})
