我建议做这样的事情:在这里我们创建一个新的 url 以添加到 wishlist( add_to_wishlist)。通过.如果用户登录,则将用户的心愿单产品显示为红色的心形符号like.js。您可以通过模板中的链接显示愿望清单产品。您可以理解我的代码中的所有其他内容。请试试这个。谢谢。music_idajaxPOST
urls.py
from django.urls import path
from main import views
app_name = 'main'
urlpatterns = [
path('', views.home, name='home'),
path('signup/', views.signup, name='signup'),
path('wishlist/', views.liked, name='liked'),
path('login/', views.login_req, name='login'),
path('logout/', views.logout_req, name='logout'),
path('add-to-wishlist/', views.add_to_wishlist, name='add_to_wishlist'), # For add to wishlist
]
views.py
def home(request):
wishlisted_list =[]
if request.user.is_authenticated:
wishlisted_list = list(Wishlist.objects.filter(user_id=request.user).values_list('music_id',flat=True).order_by('music_id'))
return render(request, template_name='main/home.html', context={"music": Music.objects.all(),'wishlisted_list':wishlisted_list})
@login_required
def liked(request):
wishlist = {}
if request.method == "GET":
if request.user.is_authenticated:
wishlist = Wishlist.objects.filter(user_id_id=request.user.pk)
else:
print("Please login")
return HttpResponse("login")
return render(request, template_name='main/wishlist.html', context={"wishlist": wishlist})
@login_required
def add_to_wishlist(request):
if request.is_ajax() and request.POST and 'attr_id' in request.POST:
if request.user.is_authenticated:
data = Wishlist.objects.filter(user_id_id = request.user.pk,music_id_id = int(request.POST['attr_id']))
if data.exists():
data.delete()
else:
Wishlist.objects.create(user_id_id = request.user.pk,music_id_id = int(request.POST['attr_id']))
else:
print("No Product is Found")
return redirect("main:home")
喜欢.js
$(document).ready(function(){
$(".like").click(function(){
var attr_id = $(this).attr('attr_id')
var action_url = $(this).attr('action_url')
var that = $(this)
$.ajax({
url: action_url,
type: "POST",
data: {'attr_id': attr_id },
headers: { "X-CSRFToken": $.cookie("csrftoken") },
success: function (result) {
console.log("Success")
that.toggleClass("heart");

error: function () {

首先,您需要在 Music 表中添加一个主键,假设您将其命名为id
在该like.js文件中,您需要进行 Ajax 调用以将音乐 ID 发送到 Django。渲染时将音乐 ID 传递给模板,以便在 Ajax 调用期间将其传回
喜欢.js
$.ajax(path, {
data: {"music_id": 12345},
method: "POST",
success: function (data, textStatus, jqXHR) {
$(selector).toggleClass("heart");
},
error: function () {
console.log("Something went wrong");
}
现在,在你看来,你可以有这样的东西 view.py
def add_to_wishlist(request):
data = json.loads(request.body.decode("utf-8"))
user_id = request.user.id
music_id = data.get('domain_name'))
wishlist = Wishlist()
wishlist.user_id = user_id
wishlist.music_id = music_id
wishlist.save()
