How do you add validation to django rest framework api
I have two models, which look like this: class Item(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=60) sku = models.CharField(max_length=60) description = models.TextField() price = models.DecimalField(max_digits=6, decimal_places=2) location = models.CharField(max_length=60) serial_number = models.CharField(max_length=60) def __str__(self): return self.name class Warehouse(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=60) def __str__(self): return self.name and they have two serializers which look like this: class ItemSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Item fields = ('id', 'name', 'sku', 'description', 'price', 'location', 'serial_number') #we need a validator that checks if location is in the list of warehouses #we need a validator that checks if sku is in the list of products class WarehouseSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Warehouse fields = ('id', 'name') I need a way to ensure that the location field for newly created items matches an existing name field from a warehouse. I also need the deletion of a warehouse to trigger the deletion of all items in that warehouse, or, failing that; if the warehouse has items, it cannot be deleted. I'm brand new to python and django, so any help would be massively appreciated! for reference, my views class looks like class ItemViewSet(viewsets.ModelViewSet): queryset = Item.objects.all().order_by('name') serializer_class = ItemSerializer class WarehouseViewSet(viewsets.ModelViewSet): queryset = Warehouse.objects.all().order_by('name') serializer_class = … -
Execute a Django view and redirect to another view like a request.POST
When I access my web page, let's say example.com, that url is associated with my index view. def index(request, pid): context = {} context['nbar'] = 'index' if request.method == 'POST': User = get_user_model() users = User.objects.all() context['users'] = users context['project_values'] = Project.objects.get(id=pid) return render(request, 'index.html', context) Inside my template (index.html) I have a button that simply changes the state of a certain project Active <-> Inactive If the user clicks the button, I want the view activate_project or deactivate_project to run in background and when the execution is finished, just reload index.html as a post.REQUEST . What I've tried: Activate - Deactivate views: def activate_project(request, pk): if request.method == 'POST': project_to_activate = ITT.objects.get(pk=pk) if project_to_activate.status == "Inactive": project_to_activate.status = "Active" project_to_activate.save() return redirect('/index/'+str(project_to_activate.id)+'/') def deactivate_project(request, pk): if request.method == 'POST': project_to_deactivate = ITT.objects.get(pk=pk) if project_to_deactivate.status == "Active": project_to_deactivate.status = "Inactive" project_to_deactivate.save() return redirect('/index/'+str(project_to_deactivate.id)+'/') The problem comes here: return redirect('/index/'+str(project_to_deactivate.id)+'/') If I use the redirect, it is treated as a GET instead of a POST. <WSGIRequest: GET '/index/5/'> In short, I need index to know that I am coming from deactivate_project or activate_project, how can I make the view index smart enough to know that? -

Django Rest Framework nested serializers AttributeError 'RelatedManager' object has no attribute
Full Error Got AttributeError when attempting to get a value for field segments on serializer BackboneLineSerializer. The serializer field might be named incorrectly and not match any attribute or key on the RelatedManager instance. Original exception text was: 'RelatedManager' object has no attribute 'segments'. I can't figure out why I'm getting this error. I'm using what I think is the exact same code elsewhere with it working. The only thing I can think of is I may have changed the related_name on the backbone_line field of the BackboneLineSegments model from something else to 'segments'. All migrations have been applied, and I don't know why it would be causing issues. Maybe the database doesn't update the new related_name correctly? I'm using Postgres in case it matters.

No reverse match error. Reverse for 'user-profile' with arguments '('',)' not found
I have created a messaging function on my website where logged in and guest users can send messages to other users. I have created an inbox for the logged in users to store these messages. When opening up a message from a guest (someone who doesn't have an account) I get an error: Reverse for 'user-profile' with arguments '('',)' not found. Based on my digging on the web I think this may be due to the fact that the guest user doesnt have a name attached? Could this be it and how would I fix it?

Django Constraining Foreign Keys for multiple nested objects
Let's start with the models: class Brand(models.Model): id = models.UUIDField(primary_key=True name = models.CharField(max_length=255) class ProductLine(models.Model): id = models.UUIDField(primary_key=True name = models.CharField(max_length=255) brand = models.ForeignKey(Brand, on_delete=models.CASCADE) class Product(models.Model): id = models.UUIDField(primary_key=True name = models.CharField(max_length=255) brand = models.ForeignKey(Brand, on_delete=models.CASCADE) product_line = models.ForeignKey(ProductLine, on_delete=models.CASCADE, blank=True, null=True) So we have brands. Brands can have 0 or more product_lines. A product always has a brand, and may also be within a product_line. My goal is to constrain the product_line of a product to also have the same brand as the product itself. For example: Brand A has 2 product_lines: Premium, Standard Brand B has 1 product_line: Platinum Suppose we have a product that belongs to brand B. I want to allow the product_line to be either null or Platinum, but not one of the product_lines that belong to Brand A (Premium or Standard) I'm not sure how to achieve this, or even if this should happen in serializers, at the model level, or somewhere else. Any help from seasoned django-ers would be much appreciated! -
Consequences of overriding __hash__ of Django models?
I have a quite complex potentially time-demanding system where Django model instances are stored and "indexed" (for the actual purpose of the system and for caching for perfomance during its execution) in sets and dicts. Thousands of CRUD operations are performed on those. Since these hashable instances are stored, this means the Django model __hashable__ method is run thousands of times: class Model(object): ... def __hash__(self): return hash(self._get_pk_val()) As efficient as this is, when called that many times, it does add up in time performance. When I use the model pk as dict keys or in sets the performance improvement is noticeable. Now, I cannot just replace all these instances with pks for practical terms, so I was thinking of overriding the method as follows in all pertinent models: def __hash__(self): return self._get_pk_val() Skipping the hash function overhead. What would be the implications and consequences of this change? Since we know the pk is unique, wouldn't this serve the same purpose in terms of indexing? Why does Django need to hash the pk? -

Problem with importing new Mongo database into the server
I have a Django-based website on the server. I am not really professional at this btw! So, I started the website on the server showing some data from MongoDB. This time I would like to change the DB to the newer one. This is what I am doing: First I drop the last DB: (On venv): $ mongo <db_name> --eval 'db.aggregation__class.drop' Then I scr (the new db) JSON-exported file into a server directory. Then I call the mongo to activate that new db: $ mongoimport --db <new db name> --collection <new db collection name> --file <server directory> I also checked if the db is activated by this: $ mongo <new db name> --eval And it is working. The problem is when I am calling it in the views.py, it does not show that it is connecting to the new db. Consider the fact that it was working with the last db! views.py # connect to MongoDb Database myclient = MongoClient(port=27017) mydatabase = myclient[db_name] classagg = mydatabase['aggregation__class'] database_text = classagg.find() Any suggestion would be appreciated.

Should i go with expressjs and mongoose or django and mongoose as the backend for my website (I'm using React for the frontend)?
I have been looking at tutorials for working in the backend of my website and our team members have also thought about using django since it comes with a lot of features(mainly giving permissions to different users is easy there) whereas i don't really have a clue about how this works using express with mongodb. Since the database used for our project is gonna be non-relational(i.e mongodb), please suggest me if i should go with express or django along with mongodb, any documents references will be much appreciated! -

Save WAV file in Django backend
I am trying to record a voice message in the frontend and send it to the Django backend to test it against a ML algorithm of voice gender prediction. In the frontend I record the voice and I use AJAX to send the blob to the backend where I try to use wave to save the file as a valid .wav. The problem is that the file that gets saved on the backend is only noise without hearing the voice at all. On the frontend I can listen to the voice recording just fine, sounding exactly as it should. I am wondering how could I save on the backend the blob that I receive as a valid WAV file? Here is the recording and blob sending logic on the frontend: <div> <div id='gUMArea'> <button class="home-btn" id='gUMbtn'>Request Stream</button> </div> <div id='btns'> <button class="home-btn" id='start'>Start</button> <button class="home-btn" id='stop'>Stop</button> </div> <div> <ul class="list-unstyled" id='ul'></ul> </div> <script src="https://code.jquery.com/jquery-2.2.0.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script> <script> 'use strict' let log = console.log.bind(console), id = val => document.getElementById(val), ul = id('ul'), gUMbtn = id('gUMbtn'), start = id('start'), stop = id('stop'), stream, recorder, counter=1, chunks, media; gUMbtn.onclick = e => { let mv = id('mediaVideo'), mediaOptions = { audio: { tag: … -

Cannot reverse a Django migration using django-otp
Been trying to write the reverse code for a Django migration. Doing the migration there were no issues, but going backwards seems to be causing an issue. My migration file is below. from django.db import migrations, models def forward_migration(apps, schema_editor): totp = apps.get_model('otp_totp', 'TOTPDevice') # Doing some stuff with the devices def reverse_migration(apps, schema_editor): totp_device = apps.get_model('otp_totp', 'TOTPDevice') # Undoing some stuff with the devices class Migration(migrations.Migration): dependencies = [ ('project', 'MY_LAST_MIGRATION'), ] operations = [ migrations.RunPython(forward_migration, reverse_migration), ] When undo the migration, I get the following error: LookupError: No installed app with label 'otp_totp'. What doesn't make sense to me about this error is that if the app can't be found while undoing the migration, why were there no issues while doing the migration? The main solution to this category of problem according to SO is to check the settings.py and to ensure that the referenced app is there correctly. My INSTALLED_APPS: INSTALLED_APPS = [ ..., 'django_otp', 'django_otp.plugins.otp_totp', ... ] This would appear correct according to the django-top docs. I've also tried quite a few variants on the app_label input to get_model function and had no luck. Thank you all in advance! -

In ViewSet in my DRF project: Let's say I have a post request in which I firstly get data from external api with requests.get, and then I serialize and return it as should be in post request. I am writing unittest with django unittest and I want to mock external api call. This is my first time with mock and I can't find such a case. To sum up: I have post function which gets data from external api if user hasn't passed something. I want to mock result of requests.get but I don't know how to implement it to test for post function I don't know If It would help you to get code snippets or my story is enough. If so, I can add it just let me know. Thanks to everyone that got through my story!
