How to get penultimate query from QuerySet in Django?
How to get penultimate item from Django QuerySet? I tried my_queryset[-2] (before check whether the my_queryset length is greater than 1) if len(my_queryset)>1: query = my_queryset[-2] and it returns: Exception Value: Negative indexing is not supported. Is there some "Django" way to get such item? The only thing which comes to my mind is to reverse the queryset and get my_queryset[2] but I'm not sure about its efficiency. -
Django - heroku, crash on deploy / run.
My app seems to run fine locally with "heroku local web" When I push it to heroku, it goes but seems to crash. I thought this was an issue with the Procfile but am now unsure.

Django rest transform flat data to relational data in serializer
I have a setup where I need to write an API for an existing javascript datamodels which i do not want to touch (for now). The javascript data has a different architecture than I want to have on the server. So my goal is to transform the data that I get from javascript to fit my database model when data is sent to the API. When data is requested from the API, it should match the expected data model of javascript. I wonder if I can do that with ModelSerializers, if yes, where is the right place to transform the data? In the view? In the serializer. My setup is like so: //javascript structure { scores: [ { id: 12, points: 2 maxpoints: 12 siteuxid: 'EXAMPLE' }, { ... } ] } //More models in django { scores: [ { id: 12, points: 2, question: { id: 12, maxpoints: 12, siteuxid: 'EXAMPLE' } }, ] } Are there any examples anyone can point me to, that achive the same? Basically it is all about having different data structures in server and client and making them compatible. Googleing did not help. -

Isn't there any way to select attributes from multiple tables by non-pk-column with hitting DB once in Django model?
I apologize for my overlong title. class Menu(models.Model): menu_code = models.IntegerField(blank=False, null=False) # It expresses order of menu items so it often can be changed. menu_title = models.CharField(max_length=20, blank=False, null=False) submenu_title = models.CharField(max_length=20, blank=True, null=True) class Board(models.Model): title = models.CharField(max_length=200, blank=False, null=False) date = models.DateTimeField(default=timezone.now) menu = models.ForeignKey(Menu) Above is a part of my models.py. And what I want to do is just like below in SQL. SELECT * FROM Board B, Menu M WHERE B.menu_id=M.menu_id and M.menu_title='cat'; or SELECT * FROM Board B INNER JOIN Menu M ON B.menu_id=M.menu_id and M.menu_title='cat'; I've seen many questions and answers about it and they supposed to use 'select_related', but mine has a slight difference with their problems. 'menu_title' isn't a PK of Menu table, so filter method of Board table cannot find that attribute. Is there any solution? Or do I have to change my model design? -
How to select related in django model so it wont generate a lot of subqueries
I have lot of models that are referring to each other in some way, for example: Port is referring to City, which in its turn refers to Country.

I assume that select_related would help me somehow in this case, but how to use it properly within the model? -

Django refer to models defined in another application -> empty QuerySet
I have an app called projects with a model Project, that I want to refer in another app called map that has the model MapData. So I can use/access the data from Project in map.html template. According to the Django Docs. To refer to models defined in another application, you can explicitly specify a model with the full application label. For example, if the Manufacturer model above is defined in another application called production, you’d need to use: class Car(models.Model): manufacturer = models.ForeignKey( 'production.Manufacturer', on_delete=models.CASCADE, ) from projects.models.py class Project(models.Model): title = models.CharField(max_length=200) text = models.TextField() date = models.DateField() featured_image = models.ImageField( upload_to='projects/featured', blank=True) lon = models.DecimalField(max_digits=10, decimal_places=8, default=1) lat = models.DecimalField(max_digits=10, decimal_places=8, default=1) location = models.CharField(max_length=200, blank=True) from map.models.py from django.db import models from projects.models import Project class MapData(models.Model): map_data = models.ForeignKey(Project) But when I access to shell, I just get an empty QuerySet. >>> from map.models import MapData >>> MapData.objects.all() <QuerySet []> In regards to my map.models.py file, I have tried OneToOneField(Project) giving me same result. And I've tried map_data = models.ForeignKey(projects.Project) giving me a NameError, and putting map_data = models.ForeignKey('projects.Project') in quotes, also giving me an empty QuerySet. Can someone please explain what I'm not understanding here. … -
