Paginate tabs element with Bootstrap - Jquery
I would like to paginate bootstrap tabs buttons. Let's say, after 50 buttons, I would like to display them paginated, so the list doesn't get too long. So far, I wasn't able to find help anywhere so I tried to figure it out by myself but I couldn't reach my goal. WHAT I WANT TO ACHIEVE I post a picture for better understanding: WHAT I ACHIEVED SO FAR let listElement = $(".paginator"); let perPage = 50; let numItems = document.getElementById("numOfQuestions").value; let numPages = Math.ceil(numItems / perPage); $(".pager").data("curr", 0); let curr = 0; while (numPages > curr) { $('<li><a href="#" class="page_link">' + (curr + 1) + "</a></li>").appendTo( ".pager" ); curr++; } $(".pager .page_link:first").addClass("active"); listElement.children().css("display", "none"); listElement.children().slice(0, perPage).css("display", "block"); $(".pager li a").click(function () { let clickedPage = $(this).html().valueOf() - 1; goTo(clickedPage, perPage); }); function previous() { let goToPage = parseInt($(".pager").data("curr")) - 1; if ($(".active").prev(".page_link").length == true) { goTo(goToPage); } } function next() { goToPage = parseInt($(".pager").data("curr")) + 1; if ($(".active_page").next(".page_link").length == true) { goTo(goToPage); } } function goTo(page) { let startAt = page * perPage, endOn = startAt + perPage; listElement .children() .css("display", "none") .slice(startAt, endOn) .css("display", "block"); $(".pager").attr("curr", page); } <div class="col-md-3"> <div class="nav nav-pills" id="v-pills-tab" role="tablist" aria-orientation="vertical"> <input type="hidden" name="" … -
How mock stripe in Django unit test
We used stripe for the payment system and stripe testing docs is its test doc. I want to mock Stripe in order to test our payment system but the stripe invoice total cost is zero all the time. I mocked stripe.InvoiceItem.create and stripe.Invoice.finalize_invoice and stripe.Invoice.create like this: @patch("app_name.models.stripe.InvoiceItem.create") @patch("trips.models.stripe.Invoice.finalize_invoice") @patch("trips.models.stripe.Invoice.create") def test_method( self, mock_create, mock_finalize, mock_invoice_item, ): response = MagicMock() # api_key and stripe_account from this link https://stripe.com/docs/api/connected_accounts response.api_key = "sk_test_MSc53AbTknQXPy" response.stripe_account = "acct_1032D82eZvKYlo2C" # Stripe account ID response.stripe_version = "2022-08-01" # last version here https://stripe.com/docs/upgrades mock_invoice_item.return_value = response response = MagicMock() geofencing_zone = GeofencingZone.objects.get(properties__name="Zone A") response.total = geofencing_zone.properties.delivery_price.price response.invoice_pdf = "https://google.com" response.id = "sk_test_MSc53AbTknQXPy" mock_create.return_value = response mock_finalize.return_value = response.id now I think maybe I should use stripe-mock somehow to mock stripe, but I can not understand how? -

Django - Updating value only for the last item of list

Is it necessary to assign a default value in model field?
As I know in Django, it requires the user to determine the default value for models fields. Like: class Student(models.Model): """Student info""" id = models.CharField( max_length=7,primary_key=True,default =-1) name = models.CharField(_('name'),max_length=8, default="x"); But I'm really annoyed at this. I just don't know what values have to be assgind in the first place. User should make the decision. Can I just Give None as the default value? What might be consequences? NPE? Give a random value. Is it specific to give a default value to the model field in Django? Or it's general to most MVC web frameworks. Or it's because of the database consideration? Thanks -

CommandError: No fixture named 'fixture' found
I'm trying to use loaddata to load some fixtures into a Django 2.2.10 project. According to the documentation, the command should look like this: python manage.py loaddata fixture app/fixtures/*.json However, when I run this command I get the following error: CommandError: No fixture named 'fixture' found. I figured the word "fixture" was being interpreted as a path to the fixture, so I removed it and it worked: python manage.py loaddata fixture app/fixtures/*.json I still find it weird though that the documentation tells me to do something that doesn't work. Am I missing something? I'm worried that I might have something wrong in my setup that is going to come back to haunt me in the future. -

Django migrations with Docker compose and volumes
I am using Django with Docker compose and all the persistent files are saved in a volume. My issue is that I am also saving my database in the volume: how does this influence migrations? I've added an new schema and there seems no way to reflect this change in the DB. When I apply the migrations on my local environment, it works, the migrations are correctly applied and I can see the new db schema, but this is because I've created a local folder app/static, which reflects the volume name of the docker-compose. Now, since the db is in that folder, it works, as the migrations are applied to the db. When I deploy my application, the db inside of the app/static remains the same old db, with the same old entries and the same old schemas. How can I apply the migrations so that the db inside of the volume app/static reflects the new changes, without losing the old entries? As a practical example I have added a new model Action, which is not existent on the server. So the DB has all the schemas but Action. Locally, I run makemigrations and migrate, producing the migration files (which … -

For example i have 4 tags and 1 tag is assigned to a post, when i edit that post to update i should get assigned tag as selected and remaining 3 tags as not selected. so that i can assign remaining tags to post if i wanted.

Signifianct Reduction in Performance after Installing Whitenoise
I installed and configured whitenoise to compress my static files, after which I ran collectstatic, and it appears everything ran successfully. It says 598 files have been post-processed. However, my CSS files are still the same size, and page load times have increased in production but are the same in development. Lighthouse scores have decreased from 95 to 87 after repeated tests. I must have configured something wrong, but I'm not sure what. Settings that probably aren't relevant have been removed for brevity.
