I want to print Products
data returned by following views on template. When I check the context its printing the correct data but when I try to print data in template it shows nothing. I checked Networks inside browser console, data is called there but I dont know why its not printing to views
Template
{% for product in products%}
{{product.name}}
{%endfor%}
My Ajax:
$(document).ready(function() {
var compare = localStorage.getItem("comparisionItems");
var compareObj = JSON.parse(compare);
console.log(compareObj)
$.ajax({
url: './compare',
type: "POST",
data: compare,
headers: { "X-CSRFToken": $.cookie("csrftoken") },
dataType: "json",
contentType : "application/json",
processData: "false",
success: function (data) {
location.reload();
},
});
});
Views.py
def compare(request):
is_ajax = request.headers.get('X-Requested-With') == 'XMLHttpRequest'
if is_ajax and request.method == "POST":
data = json.loads(request.body)
compare_ids = data['itemIds']
products = Products.objects.filter(id__in=compare_ids)
print(products)
context={'products':products}
return render(request,'./compare.html', context)
else:
return render(request,'./compare.html')
QuerySets are lazy!
When you call print() function, products queryset evaluate immediately
You can use all() so it evaluate in your template:
products = Products.objects.filter(id__in=compare_ids).all()
