包含模板中的 Django Rest Framework 表单不会接收数据

Question

我在 memberform.html 模板中显示的“网络”应用程序中有一个空表单。此模板包含在另一个“内容”应用程序的索引模板中。我在模板渲染期间收到“str”对象没有属性“数据”错误

    from django.shortcuts import render, redirect
    from django.template.loader import render_to_string
    from content.models import Post
    
    def detail(pk):
        post = Post.objects.get(pk=pk)
        context = {
            'post': post,
        }
        return render_to_string('detail.html', context)
    
    def index(request):
        about = detail(pk=1)
        how = detail(pk=2)
        donate = detail(pk=3)
        context = {
            'about': about,
            'how': how,
            'donate': donate,
        }
        return render(request, 'index.html', context)

Answer 1

您可以执行以下操作，而不是使用 detail 函数来获取 about、how 和 donate 的值：

about = Post.objects.get(pk=1)
how = Post.objects.get(pk=2)
donate = Post.objects.get(pk=3)

这可能会根据您尝试对 detail 函数执行的操作而起作用。
