Overriding get_queryset(), get_context_data() method with get_object method and get_context_data() method in a Django DetailView

Django error time out with multiple request
I am using runserver to run my Django app. Not too long ago I noticed that If there is a multiple request (lets say two user try to load the page in same time), the server freezes which means I get err_time_out error message in my browser. Is there any way to fix this problem? -
Django filter based on average of a field in reverse foreignkey

The value of rating list is ['0', '6'], I have an object in the database with average rating of 2. The object isn't returned, and I get no errors. Is it possible to query the above at the database level, or should I do it in python? -

Django multiple databases tables not created
I've been working on separate apps and have now decided to regroup them in a single project. I've went through Django docs about multiple databases and various post on SO but I can't get this working. My problem is that tables are not created when I run manage.py migrate So far I've tried to drop the default database (containing migrations history) and empty every migrations folders.

Trying to understand CBV's, but what is a good way to organize a single page with several models?
I know some about context data in views, but do you as a professional even use the built in CBV's, or how do you organize for example a profile app? In the profile view there can be one form for posting text, and one tag to display user details from a user model, and perhaps some other data from a profile model, and then maybe a list of the users friends and most popular posts and so on.. I find it really difficult to understand how to structure views for bigger projects. Are we not supposed to use ListView, CreateView, DetailView etc, in the same page, they are only for simple and fast usage for small websites? What is the standard way of doing this? Do you know of any github projects that are good examples that is not too big for a beginner to read? Thanks for your time and help. -

django-comments-xtd not accessible with wagtail?
I have installed django-comments-xtd following the quick start guide in the documentation here. When I go to access the /comments URL, I only get a 404 error, and the message 'Raised by: wagtail.wagtailcore.views.serve'. I followed the documentation without issue, and have installed other apps that work fine such as django-machina. I am using django 1.11.13, python 2.7 and django-comments-xtd 2.1.0. Why would this particular URL not be accessible? Templates exist in the correct location. My files are setup exactly the same as in the documentation, happy to provide more info but not sure what to provide right now. -

Django: Is it possible/feasible to create a type2 table
So, I've used type 2 tables in other environments to capture record status at different points in time. Is it possible to create a type2 (Valid from, valid to) table in django? This is more theoretical than actual, but I'm considering doing this for a project. Suppose I have a model that has a status field (created, paid, shipped, completed, etc..) How can I make this/update this as as a type 2 table. ORDER_STATUS_CHOICES = ( ('blank', 'Blank'), ('created','Created'), ('paid', 'Paid'), ('shipped', 'Shipped'), ) Class Order(models.Model): status = models.CharField(max_length=120, default='created', choices=ORDER_STATUS_CHOICES) order_id = models.CharField(max_length=120, blank=True) valid_from_dt = models.DateField(default=timezone.now, blank=True, null=True) valid_to_dt = models.DateField(default=timezone.now, blank=True, null=True) Now that I'm thinking of it, I think the flow would be that whenever a status change is made to update the existing record's valid_to_dt and then create a new record using same order_id, other data, new status new valid_from_dt and '9999-12-31' valid_to_dt. It seems straight forward. Is there anything I'm missing like Django (sqlite3) is horrible at Type 2 tables? -
Slug field RecursionError
In my Django project, I want to create slug field from the title. For example: title = Arduino UNO slug = arduino-uno And if the slug field exists into my DB then I want to append a digit For example: arduino-uno2 Here is title to slug generator logic: def create_slug(title): qs = IndividualProduct.objects.filter(slug=title) if qs.exists(): title = title + str(qs.last().id) create_slug(title) else: return title def slug_generator_for_image_folder(sender, instance, *args, **kwargs): if instance.slug == None: title = slugify(instance.title) instance.slug = create_slug(title) instance.save() else: pass pre_save.connect(slug_generator_for_image_folder, sender=IndividualProduct) But this code is exceeding maximum recursion limit if I want to add a digit. If I make the change of the code from if qs.exists(): ..... else: return title to if qs.exists(): ..... return title Then it is working perfectly. I have tried both the code into python shell and it is working perfectly. I am not understanding why it is not working into my Django models. -
