如何提交表单 href 在 Django?

我有一个链接，当您单击时，必须通过POST请求发送包含不可见字段的表单。 然后我必须能够获得字段值，例如：

var = request.POST.get/'name_of_var', ''/

在观看几个帖子之后，我似乎没有做到这一点。 这是我到目前为止的目标：

<form id="form-id" method="post">

<li>

<input name="name_of_var" type="hidden" value="{{ obj }}"/>

<a href="/activities" onclick="document.getElementById/'form-id'/.submit//;"> {{obj}} </a>

</li>

</form>

在我看来，我有这样的东西，但请求 POST 永远不要触发。 什么可能有问题？：

if request.POST:

 var = request.POST.get/'name_of_var', ''/

 return render_to_response/'activities/display_activities.html', var/

EDIT

: 这是我的 views.py:

def index/request/:

 if request.method == "POST":

 var = request.POST.get/'name_of_var', ''/

 return render_to_response/'activities/display_activities.html', var/



 category1 = Service.objects.filter/category = 'Sports'/

 category2 = Service.objects.filter/category = 'Dance'/

 category3 = Service.objects.filter/category = 'Music'/

 category4 = Service.objects.filter/category = 'Academics'/

 category5 = Service.objects.filter/category = 'Art'/

 category6 = Service.objects.filter/category = 'College'/



 subcat1 = []

 subcat2 = []

 subcat3 = []

 subcat4 = []

 subcat5 = []

 subcat6 = []



 for obj in category1:

 subcat1.append/obj.subcategory/

 subcat1 = list/set/subcat1// 



 for obj in category2:

 subcat2.append/obj.subcategory/

 subcat2 = list/set/subcat2// 



 for obj in category3:

 subcat3.append/obj.subcategory/

 subcat3 = list/set/subcat3// 



 for obj in category4:

 subcat4.append/obj.subcategory/

 subcat4 = list/set/subcat4// 



 for obj in category5:

 subcat5.append/obj.subcategory/

 subcat5 = list/set/subcat5// 



 for obj in category6:

 subcat6.append/obj.subcategory/

 subcat6 = list/set/subcat6// 



 return render_to_response/'activities/activities.html', {'user': request.user, 

 'category1':category1, 'category2':category2, 'category3':category3, 

 'category4':category4, 'category5':category5, 'category6':category6, 

 'subcat1':subcat1,'subcat2':subcat2, 'subcat3':subcat3, 

 'subcat4':subcat4, 'subcat5':subcat5,'subcat6':subcat6 }/
