更新多条记录的Django表单

from django.db import models

class MyModel(models.Model):
    name = models.CharField(max_length=100)
    description = models.TextField()

# 假设我们有一组对象需要更新
objs = MyModel.objects.filter(some_condition=True)
for obj in objs:
    obj.name = 'New Name'
    obj.description = 'New Description'

# 使用bulk_update批量更新
MyModel.objects.bulk_update(objs, ['name', 'description'])

from django.forms import formset_factory
from .models import MyModel

class MyModelForm(forms.ModelForm):
    class Meta:
        model = MyModel
        fields = ['name', 'description']

MyModelFormSet = formset_factory(MyModelForm, extra=0)

# 在视图中处理表单集
def my_view(request):
    if request.method == 'POST':
        formset = MyModelFormSet(request.POST, request.FILES)
        if formset.is_valid():
            for form in formset:
                if form.has_changed():
                    obj = form.save(commit=False)
                    # 可以在这里进行其他操作，比如设置额外的字段值
                    obj.save()
            return redirect('success_url')
    else:
        formset = MyModelFormSet(queryset=MyModel.objects.all())
    return render(request, 'my_template.html', {'formset': formset})
