Django admin:如何在ModelAdmin中迭代表单属性

from django.contrib import admin
from django.forms import TextInput

from .models import YourModel

class YourModelAdmin(admin.ModelAdmin):
    def get_form(self, request, obj=None, **kwargs):
        form = super().get_form(request, obj, **kwargs)
        
        # 遍历表单的字段
        for field_name in form.base_fields:
            field = form.base_fields[field_name]
            
            # 对每个字段进行迭代操作
            # 这里以修改TextInput的属性为例
            if isinstance(field.widget, TextInput):
                field.widget.attrs.update({'class': 'your-class'})
        
        return form

admin.site.register(YourModel, YourModelAdmin)
