How do I access the original data from object in python. Here I've used group by to group data. Can someone please help me with this issue?
I am trying to group data based on the following data fields I have, and when I am not able to access the original data in the fields Printing the filtered_data is giving something like "object at 0x10dd1abf0>", so I need to access the original human-readable value in the objects. data_objects = ['*', '*', '*', ......] // This is list of data items filterd_data_objects = groupby( data_objects, lambda data: (data.x, data.y, data.z) and data.p ) for filterd_data_object, _ in filterd_data_objects: x = data_object[0] // this is not working I've tried this to access the original data y = data_object[1] z = data_object[2] p = data_object[3] -

Django User model : how to make it with image and username?
I'm trying to make a user model in Django. My User fields are id(auto increment, PK), userImage(unique), username(not unique). I need to make a web application that registers & logs in only with userImage and username. I don't want to use password for the model but it seems that Django user model asks for password as a default (even when using AbstractUser). Also tried custom backend but when I try testing in admin, it still requires password. Is there a way to customize my user model? -

pipenv set path of virtual environment in vs code
I'm using visual studio code on windows 10, using python and django. The problem I have is that whenever I create a new virtual environment it takes place on its default folder, I'd like to change it to take place in the address I specify. How can I specify the folder that virtual environment takes place in? So far, I've tried different ways to solve this problem, but none of work for me, this could be because of the system and tools I'm using, I've tried setting the path variables using set command, like: set Path="~/.ven" I also looked for changing the variables of pip and pipenv but I couldn't make it work. I also searched the similar questions on stackoverflow, I couldn't find a proper answer. Also in the documentation of pipenv, I couldn't find the solution. Thanks for reading and your time. -

Add hyperlink to columns in DataTables
Im newbie in using DataTables, I created a webpage that uses client-side processing to load the data.

Non superusers unable to login and displaying password in admin - Django
In my Django project, I have a custom user class inside models.py of an app called "accounts": from django.db import models from django.contrib.auth.models import AbstractUser from localflavor.br.br_states import STATE_CHOICES class Company(models.Model): id = models.IntegerField(primary_key=True) class Client(AbstractUser): company = models.ForeignKey(Company, on_delete=models.CASCADE, default=0) role = models.CharField(verbose_name='Cargo', max_length=20) city = models.CharField(verbose_name='Cidade', max_length=20) state = models.CharField(verbose_name='Estado', max_length=2, choices=STATE_CHOICES) phone = models.CharField(verbose_name='Telefone', max_length=25) I have this variable set at my settings.py: AUTH_USER_MODEL = 'accounts.Client' But I am only able to login to the platform with a superuser. Non superusers get a wrong username or password (and they are active, I've checked). Also, in the admin page, it is showing the password of the Clients. Btw, I am using POSTGRES. 1) How can I make any user login into the platform (not admin page, but my main platform)? 2) How can I properly store their password and not show it in the admin page? Thank you. -

Specifying a custom user model in django and calling an object
Alright, so I'm a bit stuck here. I decided to create my own user model, which is turning out to be a huge head ache. And not to mention this is my first django project from scratch... So I am creating a dating app. I have a sample project of which I want to use some code and bring it over and adapt it to my project. I'm really not sure how to go about adapting some of the changes I need for my custom model. Here is the error I am getting: NameError at /mingle/ name 'models' is not defined Request Method: GET Request URL: http://localhost:8000/mingle/ Django Version: 2.2.3 Exception Type: NameError Exception Value: name 'models' is not defined Exception Location: /Users/papichulo/Documents/DatingApp/dating_app/views.py in mingle, line 113 Python Executable: /Library/Frameworks/Python.framework/Versions/3.7/bin/python3 Python Version: 3.7.3 Python Path: ['/Users/papichulo/Documents/DatingApp', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python37.zip', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/lib-dynload', '/Users/papichulo/Library/Python/3.7/lib/python/site-packages', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages'] Server time: Fri, 3 Apr 2020 00:15:57 +0000 SAMPLE code try: user = (User.objects.exclude(id=request.user.id).exclude(uservote__voter=request.user).order_by('?')[0]) except IndexError: user = None print(User.username) try: bio = models.UserProfile.objects.get(user=request.user).bio except models.UserProfile.DoesNotExist: create = UserProfile.objects.get_or_create(user = request.user) return redirect('profile') friend = models.UserProfile.objects.get(user=request.user).friends.all() context = dict(user = user, friend = friend) return render(request, 'index.html', context) My views.py def mingle(request): try: user = (Profile.objects.exclude(id=request.user.id).exclude(uservote__voter=request.user).order_by('?')[0]) except IndexError: user … -
How to query on the base_field of a Django ArrayField
Can I query the base_field of a Django ArrayField? For example, can I filter on "regions with a postcode that matches some regex" given the following model: models.py: from django.contrib.postgres.fields import ArrayField class Region(models.Model): postcodes = ArrayField(models.CharField(blank=True, null=True), blank=True, null=True) Something like Region.objects.filter(postcodes__contains__iregex=r'^SW1A.+') (obviously that doesn't work though) -
Django pgettext and format_lazy with raw regex string
As the title says... In Django 3.0 we can do: urlpatterns = [ path(format_lazy("{text_to_translate}", text_to_translate=pgettext("URL", "text_to_translate")), ] For actually translating text in the URL beyond the prefix added by i18n_patterns. However, what about re_path. What's the equivalent, if any, for being able to do: re_path(format_lazy(r"^{text_to_translate}/(?P<...>)/$", text_to_translate=pgettext("URL", "text_to_translate")), Since this is a raw string meant to be lazily compiled by re.compile. -
Different write and read operations with DRF
I am using Django Rest Framework for a project and I am running into a problem. When the frontend creates a Team they want to reference all relationships with an ID, but when getting the Team, they want the data from the relationship. How can I achieve this? models: class Team(models.Model): class Meta: db_table = "team" team_id = models.AutoField(primary_key=True) name = models.CharField(max_length=100) organization = models.ForeignKey(Organization, on_delete=models.CASCADE) class Organization(models.Model): class Meta: db_table = "organization" organization_id = models.AutoField(primary_key=True) name = models.CharField(max_length=100) class Position(models.Model): class Meta: db_table = "position" position_id = models.AutoField(primary_key=True) team = models.ForeignKey(Team, on_delete=models.CASCADE, related_name="positions") class Player(model.Model): class Meta: db_table = "player" player_id = models.AutoField(primary_key=True) name = models.CharField(max_length=100) positions = models.ManyToManyField(Position, related_name="players") serializers: class TeamSerializer(serializers.ModelSerializer): class Meta: model = Team fields = ["team_id", "name", "organization", "positions"] positions = PositionSerializer(many=True) # This is merely for output. There is no need to create a position when a team is created. organization = OrganizationSerializer() # Since an organization already exists I'd like to just give an organization_id when creating/editing a team. # I don't think the other serializers matter here but can add them on request. So when doing POST or PATCH on a team, I'd like the front end to be able to … -
Select all reverse relations Django ORM
My models are like this: class Credit(models.Model): name = models.CharField(max_length=100) product = models.ForeignKey('Products', models.DO_NOTHING) class CreditStatus(models.Model): status = models.CharField(max_length=100) credit_id = models.ForeignKey('Credit', models.DO_NOTHING) class CreditCommision(models.Model): comission = models.CharField(max_length=100) credit_id = models.ForeignKey('Credit', models.DO_NOTHING) Is it possible to select all these tables in one query? Please note that I can't change Credit model. I tried: CreditStatus.objects.select_related('credit').filter(status='ACTIVE') But it select only 2 tables, but I need to select all?
