Google Cloud App Engine (Django) and Google Cloud Storage working on a Single Domain with Custom URLs
I have a Django application working on supereye.co.uk. Django handles all URL routing such as supereye.co.uk/signin supereye.co.uk/watch etc. I am also using Google Cloud Storage that is working with Google Cloud App Engine on gs://production2.supereye.co.uk How shall I handle the routing so both App Engine and Storage can be accessible through the supereye.co.uk domain. For instance : supereye.co.uk -> Django App, Google Cloud App Engine data.supereye.co.uk -> Google Cloud Storage bucket, gs://production2.supereye.co.uk Is there any way to achieve this without relating Django App to bucket at all ? Can the bucket be accessible by its own resources? Is there any internal Google Cloud tool that will let me achieve this ? -
Best way to handle articles with Django
I'm looking for the best possible way to manage articles in Django. My idea was to load the articles as static files (there's no upload from users, so no form necessary, I guess), then create the model, but which field type to use here ? Textfield or FilePathField (in the static ?) or something else ? Then create the view and render it. The articles will be showned as cards with a summary on the index page, and each card will point to the full article page. If someone would point me in the right direction, I would appreciate. I'm checking the docs since yesterday, I might have missed the relevant part. -
Add custom admin actions to django irrelevant to objects
I want to add admin actions (for example with buttons) to django admin site that are irrelevant to particular model, for example doing administrative tasks such as optimizing database or clearing cache or log files or deleting records from multiple tables... I have seen django admin action without selecting objects, but the answers seems tricky and the solutions was selecting objects of particular model, in other ways. Is there a better to add this functionality to admin site anyway? -
How Django works with Mongodb
I need to make a Django restful api. I have a volume of data that is distributed in a tree structure with 3 attachments. I want to implement this nesting in Mongo: base->collection->object. The objects are generally the same so I don't really want to prescribe millions of models. I can draw an analogy with library: hall->stack->book. Each shelf has different books on it, but all of them are made of paper and covers. I found how to work with different databases and how to send the model to a certain database: 'default': { 'ENGINE': 'djongo', 'NAME': 'some_name', 'CLIENT': { { "host": "mongodb://.........../", } }, { "user": { 'ENGINE': 'djongo', 'NAME': 'some_name2', 'CLIENT': { { "host": "mongodb://......../", } } And accessing different databases Author.objects.using('other').all(). How to relate one model to one collection I found too: class MongoMeta: db_table = "some_collection_name" But how to combine all this I can't find. That one model can belong to different databases to different collections while being one single. -

How to post foreign key id only once in Django
class Department(models.Model): name = models.CharField(max_length=50) class Employee(models.Model): name = models.CharField(max_length=100) age = models.IntegerField() department = models.ForeignKey(Department, on_delete=models.CASCADE) I'm really wondering how to do this. Suppose there are three departments with id 1, 2, 3. So in employee model if i posted some employee with name abc and department 1. So next time if i will try to post the same department id that is 1 for another employee. I should not be able to do that. Validating this field does not work i believe because of foreign key.So how to achieve this. Any help would be really appreciated. Thank you !! -
I/O time differing on docker containers
I am running this script to test I/O performances on my docker containers. from tempfile import NamedTemporaryFile d = 500 n = 100000 with NamedTemporaryFile() as f: for i in range(n): nums = [] for j in range(d): nums.append(str(round(random.uniform(0, 1000), 3))) s = ' '.join(nums) f.write(s.encode()) f.write('\n'.encode()) Strange thing is execution time differs depending of containers On container 1 : 65.96740865707397 seconds On container 2 : 71.00589632987976 seconds The only thing differing between these 2 containers is the command docker executes : Container 1 command is : ./manage.py runserver 0.0.0.0:80 (this is django) Container 2 command is : python3 manage.py rqworker my_queue (this is django_rq) Do you have any idea why I have such a difference of 5 seconds ? Or do you know where could I investigate ? -

Different upload and download urls for Django Models's Image Field

I want to upload the image to AWS S3 and while accessing the image I want the image to route through CDN (in my case Fastly). def get_avatar_upload_path(identity, filename): file_ext = filename.split('.')[-1] file_name = f'{uuid.uuid4()}.{file_ext}' return f'{settings.AWS_MEDIA_PREFIX}{identity.uuid}/{file_name}' class Identity(identity_revision_base): """ Identity model.

It also seems that I cannot modify avatar.url once it is created. Is there any way around? -

How to execute function as a json in python?
I'm a beginner and now I'm trying to do something with django and data science. My project is to rate salesmen for their service and I want to do some magic with data science.)) (showing average ratings of salesmen and etc.) For now, I have this function: def average_values(): average_values_in_json = [] data = json_maker() df = pd.read_json(data) df = df.set_index('id') salesman_group = df.groupby(['salesperson']) for person in df['salesperson'].unique(): salesperson = salesman_group.get_group(f"{person}").mean() data = { "salesperson": person, "average": salesperson['rating'] } average_values_in_json.append(data) average_values_in_json = json.dumps(average_values_in_json) return average_values_in_json It works nice, I rendered it properly and now I want to represent graph with matplotlib. In my views.py, I have: def graph_show(request): new_data = average_values() x = [new_data[i]['salesperson'] for i in range(len(new_data))] y = [new_data[i]['average'] for i in range(len(new_data))] chart = get_plot(x,y) return render(request, 'report/graph.html', {'x': x, 'y': y}) The problem is that new_data takes string type of the return of function.

Collectstatic fails with Django 4.0 [duplicate]
I am unable to run python manage.py collectstatic with Django 4.0. Error is ....min.js references a file which could not be found .....min.js.map I believe this is due to Django 4.0 collectstatic having added manifest_storage: https://docs.djangoproject.com/en/4.0/ref/contrib/staticfiles/ This leads to error. I try to disable this by WHITENOISE_MANIFEST_STRICT = False but this does not have any affect. I run site on Heroku so I have django_heroku.settings(locals()) at end of settings.py file. Tried to fix this by adding an empty file with touch to location indicated in error message. Error is gone, but next .map-file is missing. No sense to manually fix. The question - how to disable finding .map -files in manage.py collectstatic in Heroku-setup? -

This is …
