在Django表单中创建任意表单类型的表单集

from django import forms

class MyForm(forms.Form):
    name = forms.CharField(max_length=100)
    email = forms.EmailField()
    age = forms.IntegerField()

# 在视图中使用表单类
def my_view(request):
    form = MyForm()
    return render(request, 'my_template.html', {'form': form})

class FileUploadForm(forms.Form):
    file = forms.FileField()

# 在视图中使用文件上传表单类
def upload_file(request):
    if request.method == 'POST':
        form = FileUploadForm(request.POST, request.FILES)
        if form.is_valid():
            # 处理上传的文件
            file = form.cleaned_data['file']
            # ...
    else:
        form = FileUploadForm()
    return render(request, 'upload_file.html', {'form': form})

from django.forms import formset_factory

class MyForm(forms.Form):
    name = forms.CharField(max_length=100)
    email = forms.EmailField()

MyFormSet = formset_factory(MyForm, extra=2)

# 在视图中使用多表单集
def my_view(request):
    formset = MyFormSet()
    return render(request, 'my_template.html', {'formset': formset})

from django.forms import formset_factory

class MyForm(forms.Form):
    name = forms.CharField(max_length=100)
    email = forms.EmailField()

MyFormSet = formset_factory(MyForm, extra=2)

# 在视图中使用内联表单集
def my_view(request):
    formset = MyFormSet()
    return render(request, 'my_template.html', {'formset': formset})
