如何在Django表单中根据登录用户过滤值？

# forms.py
from django import forms
from .models import YourModel

class YourFilterForm(forms.Form):
    # 定义一个过滤字段，例如根据用户过滤某个外键字段
    your_field = forms.ModelChoiceField(queryset=YourModel.objects.none())

    def __init__(self, user, *args, **kwargs):
        super(YourFilterForm, self).__init__(*args, **kwargs)
        # 根据登录用户过滤外键字段的选项
        self.fields['your_field'].queryset = YourModel.objects.filter(user=user)


# views.py
from django.shortcuts import render
from .forms import YourFilterForm

def your_view(request):
    form = YourFilterForm(request.user)
    if request.method == 'POST':
        form = YourFilterForm(request.user, request.POST)
        if form.is_valid():
            your_field_value = form.cleaned_data['your_field']
            # 根据your_field_value进行过滤操作，获取过滤结果
            filtered_data = YourModel.objects.filter(your_field=your_field_value)
            # 其他处理逻辑...

    context = {'form': form}
    return render(request, 'your_template.html', context)
