[英]Parameters in Django Page Redirection
我在視圖中有以下代碼:
def submit_affective(request):
if request.method == 'POST':
choice=request.POST['aff_choices']
urlid=request.POST['url_list']
url = Url.objects.get(id=urlid)
aff_result=Affective.objects.create(
affective=choice, url=url
)
return redirect('detail_affective',id=url.id)
def detail_affective(request,id):
boring_count=Affective.objects.filter(affective='Boring',url.id=id).count()
confusing_count=Affective.objects.filter(affective='Confusing',url.id=id).count()
engaging_count=Affective.objects.filter(affective='Engaging',url.id=id).count()
context = {
'boring_count':boring_count,
'confusing_count':confusing_count,
'engaging_count':engaging_count,
}
return render(request,'feedback/detail_affective.html',context)
我只想為在detail_affective
中已提交選擇的URL在detail_affective
顯示“無聊”,“混亂”,“參與”的submit_affective
。 請在代碼中告訴我問題。 我是否將網址ID正確傳遞給detail_affective? 我的過濾方式正確嗎?
您不能使用url.id
表達式作為過濾器參數,而只能使用url_id
:
boring_count=Affective.objects.filter(affective='Boring',url_id=id).count()
confusing_count=Affective.objects.filter(affective='Confusing',url_id=id).count()
engaging_count=Affective.objects.filter(affective='Engaging',url_id=id).count()
另外,您需要將id
作為url agrument參數添加到urlpattern:
path('detail_affective/<int:id>',views.detail_affective,name='detail_affective')
