I have a model called Inventory and another model Media with Inventory model as Foreign Key. But when filtering the data out of Inventory I need the instance of Media corresponding to that instance of Inventory and join the both. How can I achieve this in Django ORM?

While filtering Do something like this Media_data = media.objects.filter(inventory_id=pk) #here pk is the id you'll get from the url

https://gist.github.com/vashuteotia123/6ed32a541cb5392b57b99c86b905826c Please take a look at this. In views.py function call I need Media instance of every Inventory instance. A syntax help would be appreciated.

Hey guys, while using rest_framework, I have a situation where I have a few fields generated by the serializer cause they depend on the type of request, and some data sent in the url. However, I would like to return only some objects to the user based on the calculated field value (not all the objects). How can I do this?

Pass the instance of queryset that you filtered to your serializer. data = Model.objects.filter(name="something") serializer = CustomSerializer(data, many=True) return Response(serializer.data)

Pass the instance of queryset that you filtered to your serializer. data = Model.objects.filter(name="something") serializer = CustomSerializer(data, many=True) return Response(serializer.data)

As in, how to refilter the query set without the query set's rows having the distance field in the database?

Hello, django app running but no showing css. CLI shows “404 3139” for css, js files

From what I understand you need to filter the data based on the query and calculated column, am I right?

May I know the fields you need to calculate on something? I assumed that you will need to use annotate to base your filter on some calculated column. Lets assume that your data contains a column name x1 and x2. That 2 columns is needed to calculate the distance, and we need to filter the distance greater than 5. data = Model.objects.annotate(distance=F("x1") - F("x2")).filter(distance__gt=5)

Hi good evening Please is there a way to disable video or file download in django

As in you won't allow files to be download on the website

Can any one recommend a tutorial on how to make a video purchasing website Where you the admin uploads videos and someone buys them

that's too specific, search for a ecomerce tutorial instead

With ecommerce, you can buy and still buy again But in this situation, when you buy the product, it should always show in your feed as bought

well you may need to make this part but the basics fo selling things you can get from a tutorial

hey all, i wanna make a payment gateway but have zero clue of how to start anything regarding it, any helps or leads appreciated

Use prefetch_related() to get appeal_form and organization along with Appeal

Your own payment gateway like stripe, razorpay or you want to accept payments through these in your application??

Try adding a kwarg related_name on your ForeignKey field on your Jewelry model. jewel_object = models.ForeignKey( Inventoryofjewellery, on_delete=models.CASCADE, related_name="jewelry_medias") Every instance of your inventory contains a property of jewelry_medias that contains the media instance. inventories = Inventory.objects.filter(<any filter kwarg>) for inventory in inventories: inventory.jewelry_medias.image1.url

Can anyone tell me how can i show my local videos in video tag

Something like what onlyfans or YouTube movies uses

So maybe I need to get the url params before the serializer? so that maybe I factor it in the objects.filter()?

If the url parameter is needed to calculate the distance, yes you must need it firs, or make it optional. Lets assume the URL parameter is named value. if not request.get("value"): #display all the data if the value is None data = Model.objects.all() else: #Filter the data by distance of x1 and the value. data = Model.objects.annotate(distance=F("x1") - request.get("value")).filter(distance__gt=5) I may help you more if can provide a snapshot of your current code and some visual diagram on how you want your application behaves.
