Why use aggregate to find average value instead of using tutal_sum/n in django
Here we calculate using aggregate >>> avg = Book.objects.aggregate(average_price=Avg('price')) {'average_price': 34.35} But why we don’t use below concept in above. a = Books.objects.all() Avg = sum([x.price for x in a])/len(a) 34.35 I want to know use aggregate rather than second procees. -
'UserManager' object has no attribute 'validate'

Why my model field doesn't read the value of its ForeignKey, it returns its object number instead?
I created a model which has a field which I want to be a dynamic dropdown. I created another model and related them with a Foreign Key. Now everything works fine except the dropdown doesn't show the values from the other model, instead it returns its numbered objects.

Why do some model objects reset every time i redeploy and after a while of time passes in Django Heroku?
This is probably a really dumb question. Every time I redeploy my django app on heroku i get the same two instances of my object that were there before i deployed. I would like to change these. I would like to add some. I would like to delete some. But every time I redeploy, and after some time passes after I make changes, it always reverts back to what it was. It is horrible. Please let me know what I am doing wrong. NOTE: I AM ALREADY HOLDING MY FILES SOMEWHERE ELSE. I don't believe this has anything to do with the ephemeral file system, since I already am storing files somewhere else. But why is it that every time I redeploy the instances of the objects themselves (instances of the things inside Models) go away?? Thanks in advance. -

IntegrityError: UNIQUE constraint failed: auth_user.username - Django
I have a sample application that simply logs in and registers users. I am adding functionality for checking whether a username is already taken. For that, in the form code, I put a validation function as is usual in django. It's called clean_username. There are also functions like clean_email and clean to check the sanity of data. While the other two work just fine to weed duplicates, the clean_username function is particularly erroneous. Though I have added a line to check whether the username already exists, it still throws the same Integrity Error, which is exactly what I am trying to avoid. The clean_username function is of our concern here. Note: The print statements are only added for debugging purposes. Please find the code below (forms.py): from django import forms from django.forms.widgets import Widget from django.contrib.auth import get_user_model from email_validator import validate_email, EmailNotValidError from .constants import countries User = get_user_model() class RegisterForm(forms.Form): login = forms.CharField(label="Username:") password = forms.CharField(label="Password", widget=forms.PasswordInput()) confirm_password = forms.CharField(label="Confirm Password:", widget=forms.PasswordInput()) email = forms.EmailField(label="Email") def clean_username(self): print(f"Clean Username data: {self.cleaned_data}") username = self.cleaned_data.get("login") print("cleaning username...") existing_user_set = User.objects.filter(username=username) if existing_user_set.exists(): raise forms.ValidationError("Username is taken!!") return username def clean(self): data = self.cleaned_data print(f"\n\nData from cleaned data: {data}") password … -
Include a .html file in Django template that is located in a different directory

JavaScript variable doesn't loop through Django model
Topic is a CharField, summary is TextField within topic. For some reason, the JavaScript doesn't loop through summary TextField -- it just uses the very first summary TextField and simply ignores the rest. I want every summary TextField to looped through and displayed. Not just the first one. Does this make sense? Something is wrong with my JavaScript code. As you can see in the image -- second topic's (Bitcoin) summary is missing (highlighted in red) Image displaying the problem on the webpage {%for topic in topics%} <script> var i = 0; var txt = '{{topic.summary}}'; function typeWriter() { if (i < txt.length) { document.getElementsByClassName('js-typewrite')[0].innerHTML += txt.charAt(i); i++; setTimeout(typeWriter, 65); } } setTimeout(typeWriter, 1000); </script> <body> <p class="content"> <span class="typewrite anim-typewrite js-typewrite"></span> </p> </body> </div> <div id = 'mpost-text'> {{topic.text|linebreaks}} </div> <div id = 'change-text'> {%if topic.owner == request.user and user.is_authenticated %} <a href = "{%url 'new_sites:post_edit' topic.id%}">Edit entry</a> <a href = "{%url 'new_sites:delete_post' topic.id%}">Delete topic</a> {% endif %} </div> </div> {%empty%} <li>No topics have been added yet.</li> {% endfor %} {%if user.is_authenticated%} <a href="{% url 'new_sites:new_post'%}">Add Post</a> {%endif%} {%endblock%} -
loading local files in django

Assign permissions to users without admin-site
Im creating a custom role-based user-management system for my Django application. I want to know, if there is a way to assign permission to Django users via roles, without using the admin-site, because when the app gets deployed, the admin-site gets "deactivated". My idea was to use a one-to-one relationship with a role-model, which extends the PermissionsMixin class and for each new role, I define a list of permissions. Whenever the has_perm() function of an user gets called, I use the has_perm() function of the linked role. I have to point out, that the roles are also used to store specific information not related to the authentication process. -
Create a django background worker, best practices
I have an API in Django, which should consume a RabbitMQ queue. I'm currently using Amqpstorm Robust Consumer, instantiated by django command management, like this: python3 manage.py mycommand. and API runs in another container using gunicorn. My queue has a high message rate coming I. My concern is if this is the best practice to run this kind of process in the background with django. Is there a better way to run this worker? I say this because my container is closing sporadically, without logging anyone, just this message: Logs Killed. -
Django admin inline - show different read-only fields based on the user and the object
Django 2.2.24. I have an inline that I want to show different read-only fields based on the user's group and a field on the model. I tried to adapt the simple methodology I used on the model's admin page: class MyObjectInline(admin.StackedInline): ... def get_readonly_fields(self, request, obj=None): fields = super(self.__class__, self).get_readonly_fields(request, obj) if obj: if request.user.groups.filter(name=SPECIAL_GROUP).exists(): if obj.tag == SPECIAL_TAG: fields += (...) else: fields += (...) return fields This doesn't work bc of the well-known issue (bug?) that the object in the inline is the parent object for the whole admin page and not the object actually represented in the inline. In researching work-arounds, it seems like a custom form is required for the inline, and then a combination of __init__ and a clean routine for each field on the model is required? But I'd also need to pass the request object into the form, which research suggests incorporating a FormSet and/or FormFactory as well? As the complexities pile up, any advice on the right way to accomplish this would be appreciated! Thanks. -
Django pass PK from post to next page
I currently have a blog post feature on my site. I want users to be able to create sub posts (build log ) off of the main posts. I created this model with a FK to the Post model class BuildLog(models.Model): title = models.CharField(max_length=100) content = RichTextUploadingField(blank=True, null=True) date_posted = models.DateTimeField(default=timezone.now) author = models.ForeignKey(User, on_delete=models.CASCADE) post = models.ForeignKey('Post', on_delete=models.CASCADE) I then added a button on the post page and created a form. Everything is working as expected but when I submit the form I get the error null value in column "post_id" of relation "blog_buildlog" violates not-null constraint If I understand the error correctly it is saying I am not passing the PK of the post into the form.

Django many to many relationship only shows on one model in the admin
I’m new to python and django and have set a many:many relationship between the Subscriber and Tag classes (i.e. one subscriber can have many tags, and one tag can have many subscribers). In the django admin panel, viewing a tag successfully shows the connected subscribers as follows: However, viewing a subscriber does not show the tags they’re associated with: It’s like the many:many relationship is not shown on both sides. I’ve read some other similar django posts creating inlines and functions etc, but to no avail - and I want the tags to show only on the individual subscriber page rather than a column in the table before clicking on an individual subscriber. How can I get the tags to show on the individual subscriber pages? I tried with inlines but to no avail. Models.py: from django.db import models from accounts.models import Account class Subscriber(models.Model): first_name = models.CharField(max_length=100) last_name = models.CharField(max_length=100, null=True, blank=True) email = models.CharField(max_length=100, null=True) # tags: many to many field, with later option of users being able to define custom tags # tags = models.ManyToManyField(Tag, blank=true) # cannot uncomment, otherwise error: "NameError: name 'Tag' is not defined" - but already has many:many relationship - just not showing …
