Difference between request.user vs. get_user(request) in Django?
I noticed there are two ways to get a user object from request (assuming user is already logged in and the session is valid): user = request.user user = get_user(request) where get_user() is imported from django.contrib.auth. What's the difference? get_user() seems to do a lot of validation for request session. Which is better? -
Several properties with the same type Django
I have two models class Manager(models.Model): name = models.CharField(max_length=250) def __str__(self): return self.name class Project(models.Model): title = models.CharField(max_length=250, null=True, blank=True) work_statement = models.TextField(null=True, blank=True) contract_id = models.CharField(max_length=250, null=True, blank=True) note = models.TextField(null=True, blank=True) customer = models.CharField(max_length=250, null=True, blank=True) #executer = models.ManyToManyField(Manager) deadline = models.DateTimeField(null=True, blank=True) So there is logic I want Model Project to has several managers as executers but not all of them how can i do it? so for example: Project "N" can include two managers for execution i know that this way is not correct class Project(models.Model): title = models.CharField(max_length=250, null=True, blank=True) work_statement = models.TextField(null=True, blank=True) contract_id = models.CharField(max_length=250, null=True, blank=True) note = models.TextField(null=True, blank=True) customer = models.CharField(max_length=250, null=True, blank=True) executer1 = models.ForeignKey(Manager) executer2 = models.ForeignKey(Manager) deadline = models.DateTimeField(null=True, blank=True) -
Is celery-beats can only trigger a celery task or normal task (Django)?
I am workign on a django project with celery and celery-beats. My main use case is use celery-beats to set up a periodical task as a background task, instead of using a front-end request to trigger. I would save the results and put it inside model, then pull the model to front-end view as a view to user. My current problem is, not matter how I change the way I am calling my task, it always throwing the task is not registered in the task list inside celery. I am trying to trigger a non-celery task(inside, it will call a celery taskthe , using celery beats module, Below is the pesudo-code. tasks.py: @app.shared_task def longrunningtask(): res = APIcall.delay() return res caller.py: from .task import foo def dosomething(input_list): for ele in input_list: res.append(longrunningtask()) return res Periodical Task : schedule, created = CrontabSchedule.objects.get_or_create(hour = 1, minute = 34) task = PeriodicTask.objects.create(crontab=schedule, name="XXX_task_", task='app.caller.dosomething')) return HttpResponse("Done") Nothing special about the periodical task, but This never works for me.

In Django how to add login required for entire app?
Suppose I have 3 apps in my Django website app_1, app_2, app_3. app_1 and app_2 can access any user, but for app_3 I want the user should log in. Using login_required I can achieve this. But I have more than 30 views and urls. I don't want to write login_required decorator on every view function. Is there any other shortcut? -
How can I "copy" some dependencies to my project
I'm following a great course (Django/react ecommerce on udemy), however the bootstrap version that they're using is really old and a lot of stuff doesn't work on newer versions, I saw they dependencies on Github but all are conflicting when I'm trying to install by npm, I can try and force some but it'll probably make things worse. There's a way I "copy/paste" their package.json and run npm install or something to get the same dependencies on my project? I can refactor everything to newer versions of course but that'll take triple the time to finish the course. -

ElastiCache(redis) cluster mode enabled with django
I configured ElastiCache redis with cluster mode enabled. I want to connect ElastiCache with local Django. So I configured bastion host. I connected ElastiCache(non-cluster mode) with local Django. I tried cache.set(), cache.get(). It's OK. I installed 'Django-redis-cache' and 'settings.py' is like that. CACHES = { 'default': { 'BACKEND': 'redis_cache.RedisCache', 'LOCATION': 'localhost:6379', } } But I have problem when I connect ElastiCache(cluster mode) with django. I tried tunneling with ElastiCache configuration endpoint. When I use the same 'settings.py', error message is like that. 'SELECT is not allowed in cluster mode' So, I changed 'settings.py'. CACHES = { 'default': { 'BACKEND': 'redis_cache.RedisCache', 'LOCATION': 'localhost:6379', 'OPTIONS': { 'DB': 0 }, } } And then, error message is like that. 'MOVED 4205 xx.xx.xx.xxx:6379' What I have to do? There are no example which connect ElastiCache(cluster mode) with Django. -

Return newly created object after creation with ModelViewSet
We have a modelViewset: class ObjectViewSet(viewsets.ModelViewSet): serializer_class = MyObjectSerializer def perform_create(self, serializer): ... def perform_update(self, serializer): ... def perform_destroy(self, instance): ... But perform_create doesn't return the newly created object which means the 201 response only contains a few random fields that were specified during creation and not the whole new object. Is there some special way to get the object without overriding the .create() call? It seems like returning the new object is expected behavior, so I'm worried I'm doing something wrong here. -

asyncio.create_task() is not running asynchronously in async view function
I'm creating an async function to upload a video. The goal is to run the video upload asynchronously in the background without making the user wait. The user will be redirected to another page while the video is uploading. Following instructions in Python's asyncio docs, I'm using create_task() as that seems to be the simplest solution. In the following code, it works but it is not running asynchronously. HttpResponseRedirect is not running until after the video is fully uploaded. I also inserted 2 lines to check whether upload_video() is running asynchronously and it is. print('before') and print('after') are both printed to the console before the upload_video function completes. However, the final HttpResponseRedirect() does not run until all the code has been executed. async def my_async_func(request): if request.method == 'POST': video = request.FILES['video'] print('before') asyncio.create_task(upload_video(video)) print('after') return HttpResponseRedirect(... somewhere) async def upload_video(video): ... Basically despite all the async syntax & logic I wrote, the function is still running like a typical synchronous django view function. Why is this? What do I need to change to make upload_video() run asynchronously and return HttpResponseRedirect() without waiting? P.S. I also tried replacing create_task() with ensure_future() but it gave me the same result - the … -
Display a product whose ID is passed as a parameter
I would like to retrieve the product whose 'id' is passed as a parameter, how do I do this? For example here I passed the id equal to 1 Note I don't use a model but a dictionary def cart_add(request, id): dico={"produits":[{'id':1,'name':'pomme de terre','price':1250}]} mes_produits=dico['produits'] cart = Cart(request) mes_produits['id']=id product=mes_produits['id'] cart.add(product=product) return render(request, 'cart/cart_detail.html') i get this error : list indices must be integers or slices, not str
