Django AppRegistryNotReady with MongoDB models and Sql models
I'm using Django 1.11 with MongoDB and Sql, in MongoDB I have a document with results and when I try to retrieve the results from SQL saved in the MongoDB references, the next error is thrown (in view.py file): Traceback (most recent call last): ... File "/home/user/test/venv/lib/python3.5/site-packages/django/apps/registry.py", line 125, in check_apps_ready raise AppRegistryNotReady("Apps aren't loaded yet.") django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.

Different querysets in one view
I am trying to make the standard blog post web application using Django. I have multiple models in one applications. I want to display at a few posts from all the models to create an index, for which I will need to have multiple queryset inside my view for each model, which I don't know how to do. blog/models.py class topicone(models.Model): title = models.CharField(max_length=200) date = models.DateTimeField() def __str__(self): return self.title class topictwo(models.Model): title = models.CharField(max_length=200) date = models.DateTimeField() def __str__(self): return self.title class topicthree(models.Model): title = models.CharField(max_length=200) date = models.DateTimeField() def __str__(self): return self.title blog/urls.py urlpatterns = [ path('', views.indeview.as_view(), name="indexview"), path('<int:pk>', DetailView.as_view( model = topicone, template_name = "blogs/topicone.html" )), ] blog/views.py class indeview(ListView): model = topicone template_name = "tutorials/index.html" def get_queryset(self): return pythontuts.objects.all() views.py is quite useless as I am only using one model here. I tried writing a standalone view that didn't inherit from any other generic view so I could just create different contexts and pass multiple dictionaries in a view but that didn't seem to work.

What is the preferred way to handle singular global variables for a django project
I am creating a django website and there are a few global variables that should be configurable by the owner through the admin interface. Some examples of these variables are a path to a document (resume, portfolio, ...), email address, social media links... These variables are unique (only 1 resume, 1 link to instagram...). Creating a model specifically for them seems a bit overkill, because there will only ever be 1 entry in the table corresponding to that model. I know there are a few apps that provide this type of functionality, but I was wondering how this can or should be done in vanilla django? -

python __init__() missing 1 required positional argument: 'id' error tablib
I'm using Django 1.10, python 3.5.3 We are importing excel files using tablib package. Up until now everything worked fine for xls and xlsx. The Excel file was changed and added a data validation on a specific cell. I'm note sure if that's the reason, but now when trying to load the file I'm getting __init__() missing 1 required positional argument: 'id' This is the specific line of load: Dataset.load(request.data['file'].read(), 'xlsx') Seems like the error arrives from 'serialisable.py' -> from_tree() in 'openpyxl' package -
Django rest framework (DRF): Get the form as JSON

Django model aggregate sum and count at same time
So I have a query like SELECT sum(project_shares) as shares, count(*) as count FROM vv_projects Is there any syntax like below in django 2.0 Projects.objects.aggregrate(Sum('project_shares'),Count('*')) and output like {'project_shares_sum':9,'count':8} In django 2.0 count is used aggregate foreign key references so I am confused. If not I have add another orm query line to get the count. -
(Django) Running asynchronous server task continously in the background
I want to let a class run on my server, which contains a connected bluetooth socket and continously checks for incoming data, which can then by interpreted. In principle the class structure would look like this: Interpreter: -> connect (initializes the class and starts the loop) -> loop (runs continously in the background) -> disconnect (stops the loop) This class should be initiated at some point and then run continously in the background, from time to time a http request would perhaps need data from the attributes of the class, but it should run on its own. I don't know how to accomplish this and don't want to get a description on how to do it, but would like to know where I should start, like how this kind of process is called. -
django many_to_many field delet
I have two django models which I want to connect using a many to many relationship. See the below example: class A(models.Model): name = models.CharField(max_length=1000, unique=True) class B(models.Model): name = models.CharField(max_length=1000, unique=True) aa = models.ManyToManyField(A, related_name='bs', blank=True, null=True) What I am trying to figure out is what happens if I delete a record of A or of B? What I want to have happen is that the relations in the M2M are deleted, but the other object stays intact. Say an row in A is deleted, then the related rows in B should remain, only the connection through the m2m relationship should be deleted. I can't find it in the django documentation. -

Efficiently save the same time for many objects (postgresql and generally)
I have a Django project with many objects (each of them has a row in a Postgresql table). Bulks of objects have the same time value. I wonder whether it is good to use same a time field for each of the many data objects (although hundreds of them has the same value), or to create a "context" object that will save the time, and to keep for each object a reference to (in the table - the id of) a context object. Working with ids (rather than times) is faster, although with context objects two queries should be used (one for the context, and the second for data objects with the reference to the context). Assuming that saving the same time many times is a waste of space (is it?), the second option is better. I'm not a DB expert, and will be glad to hear which option is better? What else should be considered? -

Unittest sensitive_post_parameters decorator in django view
I have a view to create new users in my django project. I am applying the @sensitive_post_parameters decorator to that view to make sure the password isn't logged if there is an unhandled exception or something like that (as indicated in the comments in the source code https://docs.djangoproject.com/en/2.0/_modules/django/views/decorators/debug/). When I proceed to test the view, I would like to make sure that this protection of the sensitive information is still in place (that I didn't delete the decorator to the function by mistake or something). I am aware, since the decorator is applied to my function, I can't test it directly from the view tests. But, for example, with the @login_required decorator, I can test its effects with assertRedirects (as explained here How to test if a view is decorated with "login_required" (Django)). I have been searching for a way to do that, but I can't find one that works. I thought of something like this: def test_senstive_post_parameters(self): request = RequestFactory().post('create_user', data={}) my_sensitive_parameters = ['password'] self.assertEqual( request.sensitive_post_parameters, my_senstive_parameters ) but that gives me an AttributeError: 'WSGIRequest' object has no attribute 'sensitive_post_parameters' Any help would be appreciated.
