Django Migrations with multiple legacy databases with multiple tables in same app
Need help with migrations of already existing databases (MySQL) with lots of tables and data. These databases were manually being updated from CLI but now they need a web interface with all the stats and collaborations etc. The tables are connected between DBs and let's say there are 10tables in db1, 5 tables in db2. I have two apps 'login' and 'main'. Login: The 'default' database is being used for authentication/login. model.py is in app 'login'. Db setting for 'default' is in settings.py This is working fine. Initial migrations worked. Main: Second app, 'main', is suppose to connect to two databases, db1, db2 and fetch/update/remove data to already existing data through views. I added the mysql connector to settings.py with database parameters and it's able to connect via dbshell. Connection is working. Using 'inspectdb' I got the two models, one from each database (m1.py, m2.py). The 'models.py' in main app is empty for now. 'managed' in meta is False for all classes generated via inspectdb. Q: How to put all the tables/classes from both the databases (m1, m2) into models.py and do migrations? If I do migrate it can affect the 'default' (please correct me). If I specify the --database … -
Python/Docker - Method delete not allowed Django
I am trying to run a program using docker that will allow me to destroy requests by using a program called PostMan to do this I have set up a class named ProductViewSet which will allow me to delete a query. But when I run docker-compose up in my Visual Studio Terminal and try to run a DELETE query through PostMan it gives me an error in PostMan that says "detail": method "DELETE" not allowed. I have tried to use the @action function to try and link the destroy function from my views.py to my urls.py in the same folder using this answer Method Delete Not Allowed - destroy() method Django, I have also tried to just use my main function Product and use a router as seen in this answer "detail": "method \delete\ not allowed" django but both of these answers do not help me at all. Here is my error that I am getting in PostMan and in my Visual Studio Terminal: Postman: { "detail": "Method \"DELETE\" not allowed." } Visual Studio Terminal: backend_1 | 172.19.0.1 - - [16/Mar/2022 00:58:14] "DELETE /api/products HTTP/1.1" 405 - Here are my requirements.txt, Dockerfile, docker-compose.yml, and views.py files respectivly: requirements.txt: Django==3.1.3 djangorestframework==3.12.2 … -
Delete db.sqlite via terminal (Django)
I'm currently deploying a project to Heroku, however it returns me the following error: ValueError: Related model 'store.user' cannot be resolved. But there is a way to avoid such error locally. You simply do: py manage.py migrate store And then py manage.py migrate In other words, if I migrate separetely, I won't face such error. However, Heroku migrates all together, then the deploy fails because of this error. If I proceed locally as Heroku does, i.e. run py manage.py migrate I can effortlessly click on and delete the db.sqlite3 file and makemigrations and migrate separetely. Then the issue would be resolved. However, that's not possible when deploying to Heroku. Thus, how can I delete this file only via terminal? I have been searching, but people only say you click on the file and the delete it, which for me it is not possible. Thanks -

DRF DefaultRouter pk/slug
I noticed that sites such as SO and Reddit use <basename>/<pk>/<slug>/ for the detail view of posts, which makes me think that this should be the standard.

Django no such table: Fligts_country when trying to migrate app model using Foreign key
Intro Hi, first off thanks in advanced for helping. I am learning the Django framework and I am having trouble trying to create a simple relation between two tables in my model. I am running django and mysql in docker in two separate containers, created by a docker-compose file (code is down below) and so far I have not been able to create the tables (migrations). Problem When I execute the command: python manage.py migrate --database=mariadb I get as a result: django.db.utils.OperationalError: no such table: Fligts_country In other posts similar to this one (Django - no such table exception for example) I see that a common solution is to remove the pycache folder and migrations as well, but this is not working for me and I have been strugling for some time now... Desired Solution I need the tables to be created in the database, but most importantly I want to know what is exactly wrong with my code. I assume that there is something that I am missing about Foreign keys. My code so far Docker-compose.yml version: '3' services: travel-crawler: restart: always container_name : travel-crawler build: ./Crawler tty: true ports: - '9005:8080' volumes: - type: bind source : E:\python-code\Traveler\Crawler … -

How to iterate through queryset and get value Django
I wanna do a simple recommendation system based on users' Animals that they added. I want to show only products of a category, that's been mapped in "zwierzeta" dictionary. So basically if user has chosen that he has a horse (which is id 1, i want to show only products that have category 4) Also if user has more than 1 animals, i want to show them randomly from list of categories id. The logic seems to be fine, im just new at django and i have no idea how to actually iterate through the querysets and how to get a value(animal) from a particular queryset. The get method doesnt work. Do you have any idea how to get a particular value from a queryset? class MyAnimal(models.Model): name = models.CharField(max_length=256) animal = models.ForeignKey(Animal, on_delete=models.CASCADE, null=False) class ProductInStore(models.Model): product = models.ForeignKey('Product', on_delete=models.CASCADE) class Product(models.Model): product_category = models.ManyToManyField(EcommerceProductCategory) def list(self, request): zwierzeta = {1 : 4, 6: 5, 8: 6, 9: 6, 4: 3} qs = MyAnimal.objects.filter(user=self.request.user) #checking if there is an animal with user == self.request.user if qs: if len(qs)==1: # if user has only 1 animal, get that animals race and if compare it with the dictionary to get product__product_category … -

creating/deleting folders in runtime using heroku/django
I have developed a Django app where I am uploading a file, doing some processing using a project folder name media. Process: user uploads a csv file, python code treats the csv data by creating temp folders in Media folder. After processing is complete, these temp folders are deleted and processed data is downloaded through browser. I am using the below lines of code to make and delete temp file after processing temp = 'media/temp3' os.mkdir(temp) shutil.copyfile('media/' + file_name, temp + '/' + file_name) shutil.rmtree(temp, ignore_errors=True) To set the media root, I used the below lines in settings.py which I am sure I am not using in other parts of the code. MEDIA_ROOT = os.path.join(BASE_DIR, 'media/') MEDIA_URL = "/media/" Everything works fine when I run the app on local host. but as soon as i deployed it to heroku, it seems like these folders were not created/not found. I am looking for: Either a solution to create, read and delete folders/files in runtime using heroku, or a better way to manage files/folders in runtime. -

Django request for CAC (common access card)
I am currently running my Django application on an Apache v2.4.5.2 server. When the user hits initial page (i.e. www.djangoApp.com) they are prompted to insert their CAC and PIN. Once complete, the PIN entry pop-up goes away and the user is directed to the landing page. The issue I'm having is figuring out how to identify the user based on the HTTP response received from the external source (GCDS). In the server logs, I can see the request information, but I am unsure how to view that request in Django views. I tried to comment out all middleware so that the request would make it through, but that doesn't work. Does Apache block certain HTTP Requests? Is there somewhere I need to allow external requests?

Why does HTML/Django template execute code out of order?
This html template from my online class executes as intended, but why? It seems like it is executing out of order: It calls my python form class using Django's syntax {{form}} to inject the blank fields for the user to fill out (name, email, textbox) The user can enter and hit the "Submit" button but then (confusingly) is that it seems the {{form}} class is called again with the entry information as it then successfully prints out user input to the terminal. Why is this? html in templates.py <html> <head> <meta charset="utf-8"> <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@4.3.1/dist/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous"> </head> <body> <h1>fill out the form</h1> <div class="container"> <form method="POST"> {{form}} {% csrf_token %} <input type="submit" class="btn btn-primary" value="submitme"> </form> </div> </body> </html> Form class in views.py def form_name_view(request): form = forms.FormName() if request.method == "POST": form = forms.FormName(request.POST) if form.is_valid(): print("VALIDATION SUCCESS") print("NAME: " + form.cleaned_data['name']) print("EMAIL: " + form.cleaned_data['email']) print("TEXT: " + form.cleaned_data['text']) return render(request, 'first_app/form_page.html', {'form' : form}) Supplemental: the url that uses the html template and my forms class from django.urls import path from first_app import views urlpatterns = [path('formpg', views.form_name_view, name = 'formpg')]
