How can I inherit another model after creating one with models.Model, [(models.Model) ---> (BaseModel)]
Earlier I created a model like this. class BloodDiscard(models.Model): timestamp = models.DateTimeField(auto_now_add=True, blank=True) created_by = models.ForeignKey(Registration, on_delete=models.SET_NULL, null=True) blood_group = models.ForeignKey(BloodGroupMaster, on_delete=models.SET_NULL, null=True) blood_cells = models.ForeignKey(BloodCellsMaster, on_delete=models.SET_NULL, null=True) quantity = models.FloatField() But now I need to apply inheritance to my model, like this. [(models.Model) ---> (BaseModel)] class BloodDiscard(BaseModel): timestamp = models.DateTimeField(auto_now_add=True, blank=True) created_by = models.ForeignKey(Registration, on_delete=models.SET_NULL, null=True) blood_group = models.ForeignKey(BloodGroupMaster, on_delete=models.SET_NULL, null=True) blood_cells = models.ForeignKey(BloodCellsMaster, on_delete=models.SET_NULL, null=True) quantity = models.FloatField() BaseModel is another model I have created before but forgot to inherit it in my current model. class BaseModel(models.Model): created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) status_master = models.ForeignKey(StatusMaster,on_delete=models.SET_NULL,default=3,null=True, blank=True) I applied "python manage.py makemigrations" after changing (models.Model) ---> (BaseModel) and got this... (venv) G:\office\medicover\medicover_bloodbank_django>python manage.py makemigrations You are trying to add the field 'created_at' with 'auto_now_add=True' to blooddiscard without a default; the database needs something to populate existing rows. 1) Provide a one-off default now (will be set on all existing rows) 2) Quit, and let me add a default in models.py Select an option: 1 Please enter the default value now, as valid Python You can accept the default 'timezone.now' by pressing 'Enter' or you can provide another value.

Showing error after writing command "pip install mysqlclient" for connecting mysql with django framework
As a beginner, I try to connect mysql with django framework. For connecting mysql with django, I changed the settings.py file of "My_First_Porject" project file after creating a database named "my_first_django" in phpmyadmin - DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'my_first_django', 'USER': 'root', 'PASSWORD': '', 'HOST': 'localhost', 'PORT': '3306', } } After that I write "pip install mysqlclient" command to connect mysql with django.

Validating List Object in Python API Request from JSON Schema
I have defined the schema for validating django rest api request : { "$schema": "http://json-schema.org/draft-04/schema#", "type": "object", "required": [ "vmname", "os_env", "topology_id", "boot_type" ], "properties": { "failed_devices_list": { "type": "list", "default": [] }, "os_env": { "type": "string", "description": "Name of environment" }, "vmname": { "type": "string", "description": "Name of the VM" }, "topology_id ": { "type": "integer", "description": "Topology Request ID" }, "boot_type": { "type" : "string", "enum": [ "X", "Y" ], "description": "Type of authentication" } } } Its validating perfectly to all the parameters, except failed_devices_list. Its an optional request argument, which has to be empty by default or should have string objects like : failed_devices_list = ["VM001","VM002"] Not sure, how to do it. Any help, is appreciable. Thank you. -
Celery error when getting settings file through environment variable

Django channels with redis
I am trying to make a chat app in Django with channels. I did it from this video. But the way that is used in the video to make the app is with InMemoryChannelLayer that should not be used for production. Then I tried to make the exact same thing that made from channel docs but it didn't work. The only thing that I didn't write in the tutorial of the docs was the docker run -p 6379:6379 -d redis:5. Am I doing something wrong? Please write me an answer of how to do it. Thanks. -
Authorization flow for Microsoft graph API in django and react
I am trying to integrate Microsoft Graph API with my Django backend application. I want to be able to read, manage and send emails on behalf of users. The frontend is built with React My issue now is how the authorization flow will work. I want users to authorize the app(prolly using Oauth) on the frontend after which I will get some kind of access code that I can save on the backend and subsequently use to make requests to the graph APIs on the user's behalf Pls, how do I achieve this flow ?? Any help will be appreciated. I have been scrambling through the docs all day, need someone to point me in the right direction -
Best way to use Oauth2 (for Google Ads API) in Django (Python)
I'm a Django/Python beginner and I want to use the Google Ads API. To access that API, I need to use Oauth2. I've tried following this official example: https://developers.google.com/google-ads/api/docs/client-libs/python/oauth-web But it doesn't work for me and they say it's just a basic implementation (probably not good for production). They mention another doc (https://developers.google.com/identity/protocols/oauth2/web-server#python), but I get lost there and I'm afraid that even if I could create something that works, I would create code that is buggy or insecure (and I guess authentication is an important part to get the security right). I've seen that there are a lot of Django packages for Oauth and I guess they could be a great option for me: https://djangopackages.org/grids/g/oauth/ But I don't know which packages are better. After reading their descriptions, I'm not even sure of which ones can be used for accessing the Google Ads API using Oauth (what I want) and which ones are for creating your own Oauth authentication system (not what I want). Can you give me some recommendations or at least articles/guides to read about this? Thanks a lot! -

How to retrieve and map through items of a specific category with Django and react
I'm trying to fetch items of a particular category that then map through the category in react app. I created an API with Django restframework that returns items of such category but using a post request. Here is the code: class ProductCategoryView(APIView): serializer_class = ProductSerializer permission_classes = (permissions.AllowAny, ) def post(self, request, format=None): data = self.request.data category = data['category'] queryset = Product.objects.order_by('-dateCreated').filter(category__iexact=category) serializer = ProductSerializer(queryset, many=True) return Response(serializer.data) For instance, let's say I have 3 categories of items in the database(textbooks, journals and novels). In the react frontend app, I want to retrieve only the textbooks, map through the array of textbooks and display each textbook without displaying any item from other categories. But I have challenges implementing it since I'm using post request. By passing a specific category to the body of the request I get items in that category returned. Is it possible to use get request and filter the items from the database such that I get only the items under the category called textbook? -

Project architectures differences for Django + Vuejs (or other) integration
I'm currently looking at project setups for a Django + Vuejs project (though I guess the question is likely just as valid for other frontends, react, svelte etc.). It seems that there are mainly 2 approaches that come up often, resulting in the following project structure: The frontend embedded within the Django project (perhaps as a git submodule): root ├── djangoapp ├── djangoproject ├── manage.py ├── requirements.txt ├── static ├── venv └── vueproject ├── node_modules ├── package.json ├── public └── src Another approach is to have them at the same level from project root, as 2 seperate projects actually (or I guess both could be git submodules to a "wrapper" project), so essentially: root ├── djangoproject │ └── <django files & folders> └── vueproject └── <vue files & folders> With the 2nd approach, it seems you basically just see Django as an API. Stuff like collectstatic does not (?) come into play. In development, you need a server up to serve Django's api, and a dev server for the vue frontend. With the 1st approach (if I understand correctly), seems that you build the Vue static files, and then manage all of that with Django's collectstatic/static files management. Seems the … -

Does Google App Engine allow file caching (using Django)?
I am seeing a problem that Django's file-based caching is not functional in Google App Engine. Ideally I want to use commands such as below to read/write from a Google Cloud Storage Bucket. output = cache.get(cacheKey) #or cache.set(cacheKey, output, timeout = 60*15) I have seen some articles on memcaching, but that is not what I need. Is it possible to combine Django's file-based caching with Google Cloud Storage? How do I perform this (and what permission settings are required?)
