Relationship field in Django
I have the following structure in my models.py document: class Player(Human): name = models.CharField(max_lenght=24) jersey_number = models.IntegerField() class Coach(Human): name = models.CharField(max_lenght=24) class Team(models.Model): name = models.CharField(max_length=24) players = models.SomethinToSomething(Player) coaches = models.SomethinToSomething(Coach) I would like in my admin section to create teams and inside each team add some players and some coaches, I want that a player is related only with the team where I created it, so if I'm in team A it has to be impossible for me see and adding player of other team. I tried OneToOne() but I can link only one player and only one coach to the team. I tried ManyToMany() but when I make the second team the players of the first team are shared with the first team. What should I use? -

Custom field Choices error in Django rest framework
I currently have a problem with creating a Choice field field in the Django Rest Framework. At first, looking for solutions in google, I found the best practices to apply the solution in my project. However, I came across problems in the service remaining from the application, bring it the way to present the field. Since I need to manipulate information through fixed options, I had to follow the methodology of even creating a specific serializer for this. Before using the ChoiceField field of the DRF, I am able to correctly choose the option but cannot demonstrate the value by getting the name of the variable in the response. My wish is that the value and not the name of the variable to be displayed. For this I created the following structure: My script, called choices.py # Model custom using ENUM concept from enum import Enum from rest_framework import serializers class ChoiceEnum(Enum): @classmethod def choices(cls): return tuple((x.name, x.value) for x in cls) #Serializer custom ChoicesField class ChoicesField(serializers.Field): def __init__(self, choices, **kwargs): self._choices = choices super(ChoicesField, self).__init__(**kwargs) def to_representation(self, obj): return self._choices[obj] def to_internal_value(self, data): return getattr(self._choices, data) My Model class Discount(models.Model): class DiscountTypes(ChoiceEnum): VALUE = 'value_absolute' PERC = 'percentual' employee … -
Django REST Framework -- Many2Many/Through

Unable to extend Django 2.1 password reset template
I'm trying to extend the password reset form like so: <!-- templates/registration/password_reset_form.html --> {% extends registration/password_reset_form.html %} {% block content %} <h1> hello </h1> {% endblock %} As far as I can tell, this should take the template from /usr/local/lib/python3.7/site-packages/django/contrib/admin/templates/registration/password_reset_template.html (which exists, I checked) and replace the block content with the one at templates/registration/password_reset_form.html.

can you update a model instance without calling save( )?
I am working on a project that requires unique slugs. The slugs are dynamically created in a custom save() method using the objects name. class SlugMixin(models.Model): def save(self, *args, **kwargs): slug = striptags(self.name) self.slug = slugify(slug) super(SlugMixin, self).save(*args, **kwargs) class Meta: abstract = True name is not unique so it's possible to have multiples of the same slug. So the solution i was working with is appending the id of the instance to it's slug in a post_save. The problem here is by attempting to update the slug with the id. save() needs to be called again. def ensure_unique_slug(sender, instance, created, **kwargs): if created and Person.objects.filter(slug=instance.slug).count() > 1: instance.slug = instance.slug + '-{}'.format(instance.id) instance.save() rendering the update useless. is there anyway to update the slug without calling save() -

A quick example would be appreciated, thanks. -
Django Rest Framework get a lookup field as a list of hyperlinks
I have a model Album and a model Photo, which references the first one through a FireignKey field. I want the ModelSerializer for model Album to return a list of hyperlinks to relate entries in model Photo through a lookup field, but I only get it to return a list of ids.

No module named django, but django is installed - miniconda has interfered with path?
So to clarify, I had already got Django to work. The main thing I had done between installing Django and having this problem is that I installed miniconda3 and MySQLdb. I'm running Python 3.7.1, pip 18.1 and as far as I know should have Django 2.1.4. From /Users/me I run: python3 -m django --version and I get: /Users/me/miniconda3/bin/python3: No module named django From this I can see that the path seems to have been changed to miniconda, and I'm not sure how that has happened. If I run: pip3 install Django It then tells me: Requirement already satisfied: Django in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (2.1.4) Does anyone have either any idea of what could have happened and how to rectify it? -

How to return DateTime in different timezone from Django Rest Framework serializer
