如何在django的data视图上显示用户在外键中输入的相关数据

from .models import RelatedData

def data_view(request):
    user_id = request.POST.get('user_id')  # 假设用户输入的数据是user_id
    user = User.objects.get(id=user_id)  # 获取对应的User实例
    related_data = RelatedData.objects.create(user=user, ...)  # 创建RelatedData实例并关联User实例
    ...

from django.shortcuts import render

def data_view(request):
    ...
    context = {
        'related_data': related_data,  # 将RelatedData实例传递给模板
        ...
    }
    return render(request, 'data.html', context)

<!-- data.html -->
<h1>Related Data</h1>
<p>User: {{ related_data.user }}</p>
<p>Other Field: {{ related_data.other_field }}</p>
