Django Managemengt Command Logging Buffers Messages
When I issue log statements from a Django management command, they always get joined into one big log statement for the whole command execution. Instead, I want them to be issued individually line by line like usual application logs. That way log aggregation can pick them up properly and not as one extremely large message. LOGGING_ROOT_HANDLERS = ['prometheus', 'console'] LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'formatters': { 'json': { '()': 'pythonjsonlogger.jsonlogger.JsonFormatter', 'fmt': '%(levelname)s %(levelno)s %(pathname)s %(funcName)s %(asctime)s %(message)s', }, }, 'filters': { 'require_debug_true': {'()': 'django.utils.log.RequireDebugTrue'}, }, 'handlers': { 'console': { 'level': 'INFO', 'class': 'logging.StreamHandler', 'formatter': 'json', }, 'prometheus': { 'level': 'WARNING', 'class': 'app.logging_handlers.PrometheusHandler', }, }, 'loggers': { '': {'level': 'INFO', 'handlers': LOGGING_ROOT_HANDLERS}, 'myapp.management.commands': { 'handlers': LOGGING_ROOT_HANDLERS.copy(), 'level': 'INFO', 'propagate': True, }, 'django': { 'handlers': LOGGING_ROOT_HANDLERS.copy(), 'level': 'WARNING', 'propagate': False, }, 'django.request': { 'handlers': LOGGING_ROOT_HANDLERS.copy(), 'level': 'INFO', 'propagate': False, }, }, } import logging from django.core.management.base import BaseCommand logger = logging.getLogger(__name__) class Command(BaseCommand): def handle(self, *args, **options): logger.info("Message %s", "1") logger.info("Message %s", "2") Current output: {"levelname": "INFO", "levelno": 20, "pathname": "runcommand.py", "funcName": "<module>", "asctime": "2020-06-03 09:32:19,497", "message": ""} {"levelname": "WARNING", "levelno": 30, "pathname": "runcommand.py", "funcName": "<module>", "asctime": "2020-06-03 09:32:19,498", "message": "{\"levelname\": \"INFO\", \"levelno\": 20, \"pathname\": \"/www/app/myapp/management/commands/mycommand.py\", \"funcName\": \"handle\", \"asctime\": \"2020-06-03 … -
How to compile single python scripts (not to exe)?
I know there is a lot of debate within this topic. I made some research, I looked into some of the questions here, but none was exactly it. I'm developing my app in Django, using Python 3.7 and I'm not looking to convert my app into a single .exe file, actually it wouldn't be reasonable to do so, if even possible. However, I have seen some apps developed in javascript that use bytenode to compile code to .jsc Is there such a thing for python? I know there is .pyc, but for all I know those are just runtime compiled files, not actually a bytecode precompiled script. I wanted to protect the source code on some files that can compromise the security of the app. After all, deploying my app means deploying a fully fledged python installation with a web port open and an app that works on it. What do you think, is there a way to do it, does it even make sense to you? Thank you -
Django urlpatterns when a category is included into URL
Django 3.0.6 urlpatterns = [ path('', HomeView.as_view(), name='home'), path('{}'.format("admin/" if DEBUG else "dhjfsljdasdhje32/"), admin.site.urls), # Change admin url for security reasons. path('image/', include(('image.urls', 'image'), namespace="image")), path('polls/', include(('polls.urls', 'polls'), namespace="polls")), path('applications/', include(('applications.urls', 'applications'), namespace="applications")), ] def _get_categories_url_pattern(): """ Organize urls with posts categories. URL format: <category>/<post_slug> Example: linux/how_to_install_ubuntu/ """ categories = Category.objects.all().values_list("slug", flat=True) for category in categories: urlpatterns.append(path('{}/'.format(category), include('post.urls'))) urlpatterns.append(path('draft/{}/'.format(category), include('post.urls'))) _get_categories_url_pattern() Please, concentrate your attention on how categories in urls are handled. Problems with this code: When a new category is added in the admin site, Django project has to be relaunched (at least with the built in dev server). When last time I did python manage.py makemigrations it blew up. I had to comment out anything having anything to do with _get_categories_url_pattern. Then it made migrations. Now I can't reproduce this error anymore. But there seems to be some danger in this code. Could you help me understand how to refactor this code for it to work at least without restarting the dev server when a new category is added. -

Translation fails in django-simple-menu
I'm using django-simple-menu in my header navigation and the application has multiple languages. When switching language, the language is stored within the user preferences and everything is translated correctly except the django-simple-menu. When I stop the application and restart, the translation is also applied to simple-menu. I don't know which part of my code to publish here in order to solve the problem, but any help will be appreciated. -
Create directory as service account not the computer
I am struggling with an issue that I do not know how to solve. I am trying to make a directory with python as a different user/under the different credentials. I will explain why. Since I am not able to use internal storage on server/virtual machine but I can use a mapped drive which is on a different machine and make directory there. This will not be an issue if I will make the directory but since I am using the Django and web view the command which is started will be executed with permissions of computer which is not allowed due to the security access the mapped drive and make directory/folder. Is there any option on how to access the mapped drive with different credentials and create the directory/folder? Keep in mind that I am executing the scrip through the website so everything executed is as computer/VM. Thanks -
How to fix the " has no attribute 'objects' " error in django?

Django: Sort given results of method on model
In Django, how can I sort the results of a method on my model? class Flashcard(models.Model): owner = models.ForeignKey(User, on_delete=models.CASCADE) deck = models.ForeignKey(Deck, on_delete=models.CASCADE) question = models.TextField() answer = models.TextField() difficulty = models.FloatField(default=2.5) objects = FlashcardManager() def __str__(self): return self.question def number_of_questions(self): return self.question.count(deck=deck.id) def get_avg_diff_user(self): avg_diff = Flashcard.objects.filter(owner=self).aggregate(Avg('difficulty'))['difficulty__avg'] return avg_diff So with get_avg_diff_user, I get each user's average difficulty rating. Which I can then use in my leaderboard template as follows: <ol> {% for user in leaderboard_list %} <li>{{user.username}}: {{user.profile.avg_diff_user|floatformat:2}}</li> {% endfor %} </ol> But it's not sorted - how can I sort by avg_diff_user? I've read many similar questions on SO, but to no avail. I've tried a different method on my model: def avg_diff_sorted(self): avg_diff_sorted = Flashcard.objects.all().annotate(get_avg_diff_user=Avg(Flashcard('difficulty'))['difficulty__avg'].order_by(get_avg_diff_user)) return avg_diff_sorted Which I don't think is right and unsurprisingly it didn't return any results in my template. I also tried the following, as suggested in https://stackoverflow.com/a/930894/13290801, which didn't work for me: def avg_diff_sorted(self): avg_diff_sorted = sorted(Flashcard.objects.all(), key = lambda p: p.avg_diff) return avg_diff_sorted -
Unhandled rejection error from fetch in Javascript
I am trying to fetch some JSON file from one Rest API, which can be accessed via http://0.0.0.0:8888/model/?sentence=querys. The response essentially looks like {"out": "Test string"} Now I am starting a Django application, which resides on localhost:8000. I have a Javascript inside which is supposed to fetch the JSON and the relevant code snippet looks as follows: fetch("http://0.0.0.0:8888/model/?sentence=querys") .then(response => response.json()) .then(result => { let responseText = result.out; console.log(responseText); }); Now when I try to fetch the JSON the following error shows up: ERROR Got error: context: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.61 Safari/537.36 details: unhandledrejection, Failed to fetch, TypeError: Failed to fetch However, when I change the Url to something from the Github API, everything works as desired. Do you know how to make it work here as well? -

How to replace the DefaultRouter functionality for function based views
I like the way DefaultRouter in DRF lists all the endpoints. However I dislike the use of ViewSets and prefer using function based views. I can't seem to find a way to list all my function based views in api/v1 any easy way. Seems like you can only use DefaultRouter with ViewSets Is there any quick way and neat way to list all endpoints the same way DefaultRouter does with function based views? -
Read-the-Docs Local Instance: Docs are built successfully but cannot be found (404)
I have successfully installed an instance of Read-the-Docs locally and integrated with the public instance of Gitlab. I have successfully imported and built three projects (even a private one after some minor code alterations, though it is not normally supported). One of these projects is the default template project that RTD suggests for testing. I can view the docs in the machine where the RTD instance is installed. However, when I press the green "View Docs" button a 404 status code occurs. Supposedly, the docs should be under /docs/template/en/latest. As you can see there is no docs prefix in the available URLs: My assumption was that the endpoints regarding the docs are updated dynamically and the Django application reloads, yet I have been searching the code and I have not found anything to support this assumption. My question is, if anyone has ever come upon this issue and how / if it was resolved? -
How to store response of a Django filter in a variable which can be used in a Django template?
Below is my custom filter related code: @register.filter(name="get_quantity") def quantity(item, user_id): try: id = int(user_id) order_item = models.OrderItem.objects.filter(item=item,user__id=id) if order_item.exists(): return order_item[0].quantity except: return False Now I want to use the returned value (quantity) of the filter in my template file: template.html: {% if item|get_quantity:user_id == False %} <input class="text-center qty" value="0" style="width:30px; display: none;"></input> {% else %} <input class="text-center qty" value="{{ item|get_quantity:user_id }}" style="width:30px;"></input> {% endif %} So, I want to store the returned value of the get_quantity filter in some variable in the if condition so I can use it in the else part of code instead of calling the custom filter again in order to reduce complexity. Can someone guide me how to achieve this? -

Is there a way to convert video with open-cv in django file-field?

Deploy Django App serverless on GCP cloud functions
I have a Django webapp (a forum) which have few screens like login, profile, posts, replies, etc.. A regular deployment on dedicated instances (with scalability, performance in mind) seems to be expensive. I have come across serverless deployment of Django apps on AWS Lambda. Here is one such example on AWS. But I couldn't find anything similar on GCP. Is a similar thing possible using GCP cloud functions (GCF)?

Session ID getting changed on redirect django & docker
I have a Django and react project. I'm using Nginx and Gunicorn to run the application. To run all these I'm using docker. So in a Django view, I'm setting a session variable and then redirecting to another view after this. So in that redirected view when I'm trying to access the session variable it's not getting fetched. I'm using the default session to store the session in the django_session table. I checked there as well but I'm not sure why it's not able to fetch the session. The wired part is here that in firefox it's working but not in chrome.

How to search in a JSONField for a key with spaces in Django with Postgres?
Suppose I've a JSONField namely "data" defined in one of my models.py in Django. The Contents of the field is somewhat similar to the following - { "name": "John", "email": "johndoe@foo.bar", "last name": "Doe" } I need to write a queries of the following form - self.objects.filter(data__name="John") How do I write a similar query for the key "last name". I'm not able to proceed since that key has a space. Was thinking of getting the data and filtering it using python, But I think there would be more efficient way to get it done. I've not real control over the data in the JSONField. So, I can't really change the name of the key.
