如何解决包含模板中的Django Rest Framework表单不会接收数据
我在memberform.html模板中显示的“网络”应用程序中有一个空表单。该模板包含在另一个“内容”应用程序的索引模板中。我收到的“ str”对象在模板渲染期间没有属性“ data”错误

def detail(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,context)
解决方法
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)
这可能有效，具体取决于您要使用细节功能做什么。
