Django backend in Rest-framework resource for eCommerce
I want to create an eCommerce store's entire backend in django (using Restful framework APIs), I am looking for resource available online especially on github. Ofcourse I have done extensive research but I am unable to find anything that is recently updated and yet simple enough for me to understand, as I am not expert in django yet. All I want is a resource from where I can see overall flow and model it by using their models, views, serializers and permissions as a reference -
How can I save local video file to django FileField?
I create a local video file (.mp4) by adding a logo to an existing video with the following code: logo_path = os.path.join(MEDIA_ROOT, 'logo.png') logo = (mp.ImageClip(logo_path) .set_duration(video.duration) .resize(height=50) # if you need to resize... .margin(right=8, top=8, opacity=0) # (optional) logo-border padding .set_pos(("right", "top"))) video_path = os.path.join(MEDIA_ROOT, 'test7.mp4') audio_path = os.path.join(MEDIA_ROOT, 'temp-audio.m4a') final = mp.CompositeVideoClip([video, logo]) final.write_videofile(video_path, codec='libx264', audio_codec='aac', temp_audiofile=audio_path, remove_temp=True ) I want to save the new video to a FileField of my model.

Wagtail i18n: only show links to pages that are translated
I'm building an i18n website with Wagtail 2.11.3 and followed the documentation at https://docs.wagtail.io/en/stable/advanced_topics/i18n.html?highlight=i18n, and four languages. I also use django.middleware.locale.LocaleMiddleware to determine the user's preferred language, which "kind of" works (read below). So I have four languages: WAGTAIL_CONTENT_LANGUAGES = LANGUAGES = [ ('de', "Deutsch"), ('fr', "Français"), ('it', "Italiano"), ('en', "English"), ] Only parts of the website should be multi-lingual, some pages are only available in one language. I ended up having four page trees, one for each language, and I'm able to create translations. However, as pointed out, I have some pages that aren't translated at all, but still have a localized version (auto-created when I create a page). So here https://docs.wagtail.io/en/stable/advanced_topics/i18n.html?highlight=i18n#basic-example is an example how the language links can be implemented in the template, but I only want to show the links to pages already translated. Using django_debug_toolbar I couldn't find a template variable to check if a page is translated. How can I accomplish that? Also related: Using django.middleware.locale.LocaleMiddleware the preferred language is detected, and I'm on /about_us. However, if I not explicitly set the language code preceding the url (like /de/about_us), the following pages will change back to my browser's language as I navigate at the … -
How can you output the values in the same page?
I'm trying to build an email scrapper on Django and that when you enter a URL, the result should be outputted in the same page. For now, the result is outputted in another page but I want it to be in the same one. I don't know how should I do this. I know I should be using an AJAX request but don't know how to make the form take the action of the AJAX request. Any help I would really appreciate it! form: <form class="card card-sm" action="{% url 'emailsearcher' %}" id='InputSearch' method="GET"> <div class="card-body row no-gutters align-items-center"> <div class="col-auto"> <i class="fas fa-search h4 text-body"></i> </div> <!--end of col--> <div class="col"> <input type="text" class="form-control form-control-lg form-control-borderless" placeholder="Introduce URL" name="Email" id="InputSearch" value="{{ Email.get }}" aria-describedby="searchHelp"> </div> <!--end of col--> <div class="col-auto"> <button class="btn btn-lg btn-success" type="search" onclick="total()">Find Email Address</button> </div> <!--end of col--> </div> </form> -
How to get multiple related models with as few queries possible
I am having some difficulty linking/obtaining data from 3 models all related to one another. I'm thinking i've either designed them incorrectly or I don't fully understand how to work with parental and many-to-many fields. There are 3 models (full models shown at end of question): ClubManager Where club names are entered ClubTimetables The timetable, relevant to the ClubManager DaysOfTheWeek Mon-Sun, used by ClubTimetables For which I am trying to retrieve information from all of them: the name of the club, its timetable(s) and for each timetable the days of the week it's linked to. However, I can't seem to do it in a way that doesn't constantly hit the database. First thing I tried was to get ClubManager and select_related it's timetable but couldn't figure out how to preselect the DaysOfTheWeek it was connected with. The approach I am trying now is to instead get the ClubTimetable and use select_related and prefetch_related on both the models it's linked with, like so timetable = ClubTimetables.objects.select_related('attached_to').prefetch_related('weekday') for t in timetable: print(t.attached_to.name) This results in such a query connection.queries [{'sql': 'SELECT "club_clubtimetables"."id", "club_clubtimetables"."sort_order", "club_clubtimetables"."address_line_1", "club_clubtimetables"."address_line_2", "club_clubtimetables"."address_city", "club_clubtimetables"."address_county", "club_clubtimetables"."address_country", "club_clubtimetables"."map_coord_lat", "club_clubtimetables"."map_coord_lon", "club_clubtimetables"."attached_to_id", "club_clubtimetables"."start_time", "club_clubtimetables"."end_time", "club_clubmanager"."id", "club_clubmanager"."name" FROM "club_clubtimetables" INNER JOIN "club_clubmanager" ON ("club_clubtimetables"."attached_to_id" … -
DRF: Route with and without arguments
I have a pretty simple urls.py: router = routers.DefaultRouter() router.register(r'products', views.ProductViewSet, basename = "product") urlpatterns = [ url('^api/', include(router.urls)), ...] where Product looks like this: class Product(models.Model): user = models.ManyToManyField(User, related_name="User", blank = True) name = models.CharField('name', max_length=120) What I want is a view that returns products from a user, if a user is handed to it, and returns all products when no user is submitted. I read multiple posts 1, 2, 3 but I could not solve it. Getting all products works: class ProductViewSet(LoginRequiredMixin, viewsets.ViewSet): login_url = "/login/" def list(self, request): data = [{"products": Product.objects.all(),}] results = ProductSerializer(data, many = True).data return Response(results) Serializer.py: class ProductSerializer(serializers.Serializer): products = serializers.CharField(max_length = 120) Can I add another method to my ProductViewSet, and how do I have to alter the urls.py so that I can call (for User with id=1): http://127.0.0.1:8002/api/products/1 -

Django change value in queryset from null to string
I'd like to change the value of specific properties in a queryset from null and "null" to "Field does not exist" and "Field exists but does not have value". The model contains a property for custom fields that is returned as null if the field doesn't exits, or "null" if the field exists but does not have a value. Thus the returned list has the following objects: [ "object_1": { "custom_field": null }, "object_2": { "custom_field": "null" } ] I'd like to change both of these values to "Field does not exist" and "Field exists but does not have value" in the result but I do not want to update these values, just change how they are returned. Is that possible? -

Consume an API in Django REST, server side, and serve it ,client side, in Angular
I have an Angular app that consume API client side. Since it's bad practice to do so (I don't want to expose my API credentials), I decided to split into backend/ frontend before myapp get to big. I succeed to implement my Angular into a Django REST framework app and everything is working fine. But now I need to change my API logic and have DRF consume the external API I had: Angular <---API---> ext data Now I have: Django/ Angular <---API---> ext data What I need: Angular <---API---> Django <---API---> ext data But I am very confused about how to accomplish it. I have experience with setting up API endpoints in DRF, but only for data from models within DRF. I know as well how to consume API in Django. But how can I chain two API calls? Do I have to create a model to store the queries and then the response? Do I need to write serializers even if the returned data is json all the way? How my frontend will now that the data from the external API is available? What I need is someone to explain me what is the pattern for this task. -

Django Javascript: Why Won't My Function Change The Styling
