Custom model form on admin tabular inline gives Integrity Error

How to automatically update a field depending on the user who changed it in Django?
Context:In the Blog part of page any registered User can post, but all posts that are from non superuser accounts have to be approved by an admin on the Admin page where I registered the model as well. This functions as intended. My question: How can I make it so that if a Blog Post gets updated by a superuser(doesn't matter what kind of a change for example: when admin opens one single post and adds in a further text in the body of the post, or deletes some part of a text because it seems malicious or fake), that it is automatically approved(The field approved gets then set to TRUE)? I already thought of adding a further field in the model called changed_by and have it initially null. CODE: blog/models.py from django.db import models from django.utils import timezone from django.contrib.auth.models import User from django.urls import reverse class BlogPost(models.Model): title = models.CharField(max_length=100) content = models.TextField() date_posted = models.DateTimeField(default=timezone.now) author = models.ForeignKey(User, on_delete=models.CASCADE) approved = models.BooleanField(default=False) changed_by = models.ForeignKey(User, default=None) # I am planning to use this but how? def __str__(self): return self.title def get_absolute_url(self): return reverse('blogPost-detail', kwargs={'pk': self.pk}) blog/admin.py from django.contrib import admin from .models import BlogPost def approve_multiple_posts(modeladmin, request, … -

Looking for a better way to do timezone based notifications in Django 3
I'd like to send an email to all users who have not entered a journal entry today. I'd like to give them until 8PM their local time to enter the journal entry, and got this working, but the code is fugly and I'm wondering if there's a more efficient way to accomplish my goal. I currently save the user's timezone offset when they sign up. <style> #clientTimezone { opacity: 0; width: 0; float: left; } </style> .... <form class="signup form-default row" id="signup_form" method="post" action="{% url 'account_signup' %}"> {% csrf_token %} <input type="text" name="client_timezone" id="clientTimezone" required /> .... <script> $(document).ready(function(){ var d = new Date(); $('#clientTimezone').val(moment().format('ZZ')) }) </script> And then the email code is in my dailyreminder.py management command, which triggers every 10 minutes.

What change the name of file my frontend search from backend?
My backend is using Django. My static files is using https://docs.djangoproject.com/en/3.0/ref/contrib/staticfiles/#django.contrib.staticfiles.storage.StaticFilesStorage to storage my internal files. When i access my files from my site, the request search for this file: internal.6a7c4d7e1c1e.css. This name is generated somehow i don't know in my front. The problem is, a week ago my site is going without any erros. But when i tag my commit to 0.0.1 and i make my release the site is looking for this internal.4188f59d19d7.css. But this file don't exists im my folder and the site goes without styles. The Django put all my static files to /home/developer/collected_static/. The main.css (Which is my principal file is there). Also i have other files internal files like: external.004173246553.css internal.241e6043ba27.css internal.6a7c4d7e1c1e.css internal.a9a9e1a85ca5.css internal.f6d3eedfe205.css main.2bd12da67323.css main.81c12e8cbd67.css main.d3f7640e234d.css external.009bd21e09d2.css internal.2d4b4f251635.css internal.7092cae68a42.css internal.b173cdd8c8ff.css main.048ff141018e.css main.431950216205.css main.88db1011af20.css main.d6e12dd31035.css.....

How to implement video calls over Django Channels?

How can I include a ManyToMany field into django admin fieldsets?
I have two models: Python 3.7 class ClassOne(models.Model): name = models.CharField(max_length=10, default='') class ClassTwo(models.Model): name = models.CharField(max_length=20, default='') class_ones = models.ManyToManyField(ClassOne) Now I would like to show ClassOne in django-admin with all ClassTwo's listed. I already tried to create a Tabular (admin.TabularInline) or create a method in ClassOne as following: def get_class_twos(self): return self.classtwo_set.all() and include that method in the fieldsets, but that did not work either. Neither did directly putting classtwo_set.all() or classtwo_set in the fieldset list. -
How to render django formset in row
I would like to render each form in a django formset into x amount of forms per row. For example, if the formset has 5 forms to display, I would like two forms in the 1st row, two forms in the 2nd row, and the last one in the 3rd row. Bear in mind that I would want to specify the max number of forms per row. So far, this is what I have: <form method="POST" enctype="multipart/form-data" style="margin-left: 40px; margin-right: 40px"> {% csrf_token %} {{ formset.management_form }} {{ formset.non_form_errors }} {% for forma in formset.forms %} {% cycle 'row1' 'row2' %} <div class="card "> <div class="card-header bg-secondary"> {{ forma.attackPatternID.value }} : {{ forma.attackPatternName.value }} </div> <div class="card-body"> {{ forma.attackPatternRating }} {{forma.selectionReason }} </div> <div class="card-footer"> {{ forma.attackPatternID.value }} : {{ forma.attackPatternName.value }} </div> </div> {% endfor %} <input class="btn bg-success" type="submit" value="Update" /> </form>``` But I am still getting the each form in the formset 1 per row. If there is a form in the formset, I would first create card a bootstrap card to the form fields in the card-body. This is what I would like: Form 1 Form 2 Form 3 Form 4 Form 5 But I am … -
How to rename GraphQL type field autogenerated from Django model?
I've a model in Django with some fields. Let's say this exemplary one: # <app>/models.py from django.db import models class Something(models.Model): first_field = models.Charfield() second_field = models.Charfield() I use DjangoObjectType from graphene_django to map Django models to GraphQL types. # <app>/schema.py from graphene_django import DjangoObjectType from .models import Something class SomethingType(DjangoObjectType): class Meta: model = Something Cause of auto camelcasing the model field second_field results in secondField in the GraphQL type. Now I'd like to rename the GraphQL type field from secondField to somethingFancy. How can I get this done easiest? -
Allow to create ForeignKey relation under specific condition
I am struggling with given scenario. I have a following model: class Location(models.Model): COUNTRY = 1 REGION = 2 region_type_choices = ((COUNTRY, 'country'), (REGION, 'region')) name = models.CharField(max_length=120, blank=False) country_code = models.CharField(max_length=10, blank=False) region = models.CharField(max_length=10, choices=region_type_choices) is_recommended = models.BooleanField(default=False) countries = models.ForeignKey('Location', related_name='related_countries', on_delete=models.DO_NOTHING) What I'd have to achieve here is: you can only add a new object to countries relation if a Region instance you are trying to add has region attribute set to country and the base instance is set to region. In example: country = Location(name='test', region=1) region = Location(name='test2', region=2) region2 = Location(name='test3', region=2) region.related_countries.add(country) <-- this is valid country.related_countries.add(region) <-- this is invalid region.related_countries.add(region2) <-- this is also invalid Is this even possible to achieve with single table in Django? I've already tried overriding post_save and save signals but that didn't seem to work. I'd appreciate any tips.
