Python Django - Associating a OneToOneField on users. IntegrityError NOT NULL constraint failed
I'm making a website (obviously) with Django and I have a problem with when I create users. I want to associate my users with a model, called a Class, and the Class contains multiple users. And I assume I need to use models.OneToOneField() to associate one class with multiple users. But when I, for example, create a superuser in the terminal, I instantly get an IntegrityError when I have typed the last bit of required information and pressed enter. I know you could just set null=True in the OneToOneField but then the user isn't associated with a class. Basically, I just want a model called a Class to have multiple users associated with it, and every Class have different Keys/authentication (as shown in models.py) to do different things on my website. Full traceback (after trying to create superuser): Traceback (most recent call last): File "C:\Users\lll20\Documents\PYJA\pyja\p_env\lib\site-packages\django\db\backends\utils.py", line 84, in _execute return self.cursor.execute(sql, params) File "C:\Users\lll20\Documents\PYJA\pyja\p_env\lib\site-packages\django\db\backends\sqlite3\base.py", line 383, in execute return Database.Cursor.execute(self, query, params) sqlite3.IntegrityError: NOT NULL constraint failed: users_user.parent_class_id The above exception was the direct cause of the following exception: Traceback (most recent call last): File "manage.py", line 21, in <module> main() File "manage.py", line 17, in main execute_from_command_line(sys.argv) File "C:\Users\lll20\Documents\PYJA\pyja\p_env\lib\site-packages\django\core\management\__init__.py", … -
How to differentiate account types in Django?
Thanks in advance if you're reading this... I'm a High School student working on a web application using Django, to help students find internships, and facilitate parents posting internship offers -- a sort of marketplace if you will. I'm trying to create a profile/account page for the users but I need a way to differentiate between whether the account logged in is a Student or Employer so that I can use views.py to generate a page appropriate to their account. In models.py, I have two different profile types which can be associated with a user account (handled by django.contrib.auth), see below for reference. class Student(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) profilePic = models.ImageField(default='default.jpg', upload_to='profile_pics') class Meta: verbose_name = 'Student Profile' def __str__(self): return f"{self.user.username}'s Profile" class Employer(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) profilePic = models.ImageField(default='default.jpg', upload_to='profile_pics') company = models.CharField(max_length=100, default='Unspecified') class Meta: verbose_name = 'Employer/Parent Profile' def __str__(self): return f"{self.user.username}'s Profile" In my views.py page, I'm trying to create a view for the account/profile that can detect whether the currently logged-in user's profile is linked to either the 'Student' or 'Parent' model and serve a page accordingly. I've tried a very rudimentary approach, as below, but unsurprisingly it's not working. def account(request): … -
View to Download FileField From Django
I have files which are saved to the MEDIA_ROOT - and I am displaying the file paths as URLs in a table in my UI. I would like for these files to download when the user clicks the link in the table.

Django: How to limit TimeField to hours and minutes only (comparison issue)
I'm developping a web api using django, I have a TimeField that stores hours:minutes:seconds, since it will be compared to a hours:minutes (without seconds) coming from the mobile app, the comparison will always fail. here is a comparison without seconds which is returnning an empty QuerySet: >>> journey = Journey \ ... .objects \ ... .filter((Q(route__departStation=1) | Q(route__stop__station_id=1)), ...

models.CASCADE not working correctly in DeleteView
models.CASCADE does not seem to function correctly when I try to delete a parent object in the delete view. I have two models. ExceptionReport and ExceptionReportHistroy.

python - logging: How to access handler from config file

How can I optimize loops within a Django template?
I have a database setup where I have the following schema: The main model is the Group. Under each group are an arbitrary number of Rules. Each Rule contains an arbitrary number of Regex's and Contacts. I'm displaying this whole set up under the main page so it looks something like this: Group A - Rule A - Regex 1, Contact 1, Contact 2 - Regex 2, Regex 3, Contact 3 - Rule B - Regex 5, Regex 6, Regex 6, Contact 4 - Regex 7, Contact 7, Contact 6 Group B - ... The db query itself is not terribly complex. It's basically: for group in groups: r = Rule.objects.filter(group=group) rules[group]= r But the template rendering is what is slowing things down. It's taking about 7 seconds to render the template because of the number of nested loops: {% for group, rules in rules.items %} {% for rule in rules %} {% for regex in rule.regexes.all %} {{regex.name}} {{regex.type}} {{...}} {% endfor %} {% for contacts in rule.contacts.all %} {{contacts.name}} {{contacts.email}} {{...}} {% endfor %} {% endfor %} {% endfor %} There's obviously more HTML in here but even without it, this rendering takes about 3-4 seconds (full template … -
How to create a dropdown menu in django with selections from created model objects?
I just want to create a dropdown menu with values from formerly created objects (instruments). In this case objects in the Instrument class.

How to check form field value before posting form - Django
I have a form that currently works great with the exception that a user can input any value they want into one of the form fields. I would like to first check the field value when the user presses the submit button, before the form is actually submitted. Where is the best place to do this, I am assuming in the views.py? My objective is to check the customerTag value that the user inputs, and ensure the value they enter exists in the CustomerTag model field. for my views.py I currently have: def usersignup(request): if request.method == 'POST': form = CustomUserCreationForm(request.POST) if form.is_valid(): user = form.save(commit=False) user.is_active = False user.save() current_site = get_current_site(request) email_subject = 'Activate Your Account' message = render_to_string('activate_account.html', { 'user': user, 'domain': '127.0.0.1:8000', 'uid': urlsafe_base64_encode(force_bytes(user.pk)).decode(), 'token': account_activation_token.make_token(user), }) to_email = form.cleaned_data.get('email') send_mail(email_subject, message, 'example@example.com', [to_email,], fail_silently=False) return render(request, 'confirm.html',) else: form = CustomUserCreationForm() return render(request, 'signup.html', {'form': form}) forms.py I have: class CustomUserCreationForm(UserCreationForm): def __init__(self, *args, **kwargs):# for ensuring fields are not left empty super(CustomUserCreationForm, self).__init__(*args, **kwargs) self.fields['email'].required = True self.fields['first_name'].required = True self.fields['customerTag'].required = True class Meta(UserCreationForm.Meta): model = CustomUser fields = ('username', 'first_name', 'last_name', 'email', 'customerTag',) labels = { 'customerTag': ('Customer ID'), } help_texts = … -
How to enforce certain settings (of another app) for a Django Reusable App
I am writing a Django Reusable App. Parts of this app require certain other Django Reusable Apps, and critically require certain settings for those apps. For example, suppose that in order to use my_reusable_app you have to also use rest_framework and set: REST_FRAMEWORK = { "DEFAULT_SCHEMA_CLASS": "rest_framework.schemas.coreapi.AutoSchema", } (This is a silly example, but you get the idea.) How can I enforce this? My first thought is to use Django's built-in checks framwork. Any better ideas? -

Here's the message I get when I run the file: Traceback (most recent call last): File "populate_PlzWorkApp.py", line 5, in django.setup() File "C:\Users\FiercePC\Anaconda3\envs\myDjangoEnv\lib\site-packages\django__init__.py", line 16, in setup from django.urls import set_script_prefix File "C:\Users\FiercePC\Anaconda3\envs\myDjangoEnv\lib\site-packages\django\urls__init__.py", line 1, in from .base import ( File "C:\Users\FiercePC\Anaconda3\envs\myDjangoEnv\lib\site-packages\django\urls\base.py", line 8, in from .exceptions import NoReverseMatch, Resolver404 File "C:\Users\FiercePC\Anaconda3\envs\myDjangoEnv\lib\site-packages\django\urls\exceptions.py", line 1, in from django.http import Http404 File "C:\Users\FiercePC\Anaconda3\envs\myDjangoEnv\lib\site-packages\django\http__init__.py", line 2, in … -
Django: Hiding specific ForeignKey Objects
I've got these two models: class User(AbstractBaseUser, PermissionsMixin): club = models.ForeignKey('schedule.club', on_delete=models.CASCADE, null=True, blank=True) archived = models.DateTimeField('Archived at', blank=True, null=True) class Club(models.Model): archived = models.DateTimeField('Archived at', blank=True, null=True) some fields more fields Now when creating a new User for the field club I can always pick from a list of all my club objects. But for my Clubs I've got a archive function which is inside my models.py and does the following: def archive(self, user): self.name = 'Archived Club' self.archived = now() So they are not getting deleted. Only their data get anonymised and they basically still exist in the DB. And exactly those Clubs I don't want to see anymore when creating a new User and setting his/her club. Is there a way to do that without changing the club field in my form? Thanks for anyone who can help! :) -

How to create custom filter using graphene-django and Relay that use multiple fields of different types?
Problem Hello, I'm using Graphene Django and Graphene Relay with Python 3.7. I'm trying to make a custom filter for the requests in GraphQL using Django filters. My table looks like this: | id(type: int) | flow(type: varchar) | datetime(type: datetime) | duration(type: int) | |---------------|---------------------|--------------------------|---------------------| | 1 | aaa | 2019-07-06 08:59:00 | 113095465 | | 2 | xxx | 2019-07-06 08:59:00 | 113095465 | | 3 | bbb | 2019-07-06 08:59:00 | 113095465 | I want to be able to execute this kind of SQL request using GraphQL: SELECT * FROM tablename WHERE datetime <= "2019-07-06 08:59:00" AND DATE_ADD(datetime, INTERVAL duration * 1000 SECOND) >= "2019-07-06 09:00:00"; Using a graphql query like : (of course the dates would be in Python DateTime Format) { allTable(startDate: "2019-07-06 08:59:00", endDate: "2019-07-06 09:00:00") { edges { node { id name } } } } Code models.py from django.db import models class TableName(models.Model): name = models.CharField() datetime = models.DateTimeField() duration = models.BigIntegerField() class Meta: managed = False db_table = 'tablename' schema.py from graphene import relay, ObjectType from graphene_django import DjangoObjectType from graphene_django.filter import DjangoFilterConnectionField import django_filters from .models import TableName from .fieldList import fields_table class TableFilter(django_filters.FilterSet): class Meta: model = TableName fields …
