在Django中处理表单并检查是否所有输入字段都已输入

from django import forms

class MyForm(forms.Form):
    field1 = forms.CharField(max_length=100)
    field2 = forms.IntegerField()

    def clean_field1(self):
        data = self.cleaned_data['field1']
        if not data:
            raise forms.ValidationError("Field 1 is required.")
        return data

    def clean_field2(self):
        data = self.cleaned_data['field2']
        if not data:
            raise forms.ValidationError("Field 2 is required.")
        return data

from django.shortcuts import render

def my_view(request):
    if request.method == 'POST':
        form = MyForm(request.POST)
        if form.is_valid():
            # 处理表单数据
            # ...
    else:
        form = MyForm()

    return render(request, 'my_template.html', {'form': form})
