Use __str__ children classes methods when calling parent class
I've some classes like these : class Event(models.Model): beginning = models.fields.DateTimeField(null=False, blank=True, default=date.today) end = models.fields.DateTimeField(null=False, blank=True, default=date.today) class Festival(models.Model): name = models.fields.CharField(max_length=100, blank=True) def __str__(self) -> str: return f"{self.name}" class FestivalEdition(Event): type = "festival_edition" father_festival = models.ForeignKey(Festival, default="", on_delete=models.CASCADE, related_name="edition") def __str__(self) -> str: return f"{self.festival_name} {self.year}" As you can see, only the children classes have their __str__ methods. When I use Event (by the admin interface or by shell), the name is like this <Event: Event object (1)>. How can I use the __str__ methods of the children (and children of children) classes when calling the parent class ? I've read the official documentation of Django about inheritance and this post. I tried this : class Event(models.Model): objects2 = InheritanceManager() # The __str__ of Event call the __str__ of children models def __str__(self) -> str: event_name = Event.objects2.filter(pk=self.pk).select_subclasses()[0].__str__() return f"{event_name}" It works well but only with the children but not the children of the children because I get this recursion Error in this case : RecursionError: maximum recursion depth exceeded while calling a Python object. -

Session or Token auth for Backend and two Frontend apps at different locations
I have a Django App which acts backend and some endpoint built with Django REST Framework. There are 2 pieces of frontend interacting with my Django app. I have not implemented auth/login to my app. But before i do that, i have few questions to ask. Below is a picture of the system. Both React_user is a React app BUT React_admin is a low-code app like Retool (drag & drop components to make UI connected via REST API to backend) which is sitting at differnt servers i.e physically seperated at differnt locations React_user is the app for customer where they should be able to login with username and password created by React_admin React_admin is the on who creates customers, create username, password for each customer. Think of this as walk-in account creation as there is no sign-up for customers. So, React_admin creates customer credentials from the React app managed by admin, again is sitting at differnt server. For simplicity, let's say React_admin is hosted at the office itself. To create users, i'm using basic django Users model comes out of the box.So, to create a user, there is a an endpoint made with Django REST Framwork. The endpoint is https://mapp.com/rest/create_user … -
Django Plotting Separate Models By Date Month In Highcharts
I have two models that I'm trying to plot counts of each by month on a single chart in Highcharts class Foo(models.Model): foo_user = models.ForeignKey(User, on_delete=models.CASCADE) foo_title = models.CharField(max_length=200) foo_date = models.DateTimeField() class Bar(models.Model): bar_user = models.ForeignKey(User, on_delete=models.CASCADE) bar_title = models.CharField(max_length=200) bar_date = models.DateTimeField() I get the data, combine the querysets, and sort by month foo_data = Foo.objects.annotate(month=TruncMonth('foo_date')).values('month').annotate(foo=Count('id')).order_by('-month') bar_data = Bar.objects.annotate(month=TruncMonth('bar_date')).values('month').annotate(bar=Count('id')).order_by('-month') data = chain(foo_data, bar_data) ordered_data = sorted(data, key=lambda obj: obj['month'], reverse=True) At this point I'm lost and feel like my whole approach is most likely all wrong, but I can't figure out what to do - I add the data to lists and send to the Highchart plot like so. I've gotten it to work if both Foo and Bar both have items in each month, but as soon as one one has an object in a month where the other doesn't the whole thing is throw off. chart_labels = [] foo_chart_data = [] bar_chart_data = [] for row in ordered_data: if row['month'] not in chart_labels: chart_labels.append((row['month']).strftime("%B %Y")) if 'foo' in row: foo_chart_data.append(row['foo']) else: pass if 'bar' in row: bar_chart_data.append(row['bar']) else: pass This is Highchart setup Highcharts.chart(chartContainer, { chart: {type: 'column'}, title: {text: 'Foos & Bars Created'}, xAxis: {categories: … -
Django Pass tag dynamic to div class
I have a progress bar in a table similar to this: I can pass the value "2" for the percentage, but I cannot pass the value 2 to the aria-valuenow class that sets how fill is shown the progress bar. How could I pass the dynamic value to aria-valuenow so the progress bar shows the right filling? I tried {{value.3}},"{{value.3}}", the same with only one {} and with/without % %. I really run out of imagination. {% for key,value in ctxt.items %} <tr><td>{{value.0}}</td><td>{{value.1}}</td><td> {% if value.3 %} <div class="progress align-content-center position-relative" style="height: 25px;"> <div class="progress-bar" role="progressbar" style="width: 25%;" aria-valuenow= "{% value.3 %}" aria-valuemin="0" aria-valuemax="100"></div> <small class="justify-content-center d-flex position-absolute w-100">{{value.3}}%</small> </div> {% endif %} </td></tr> {% endfor %} *Another battle is to put the "2%" vertically centered and not in the top with the position-absolute commands. If you know this, really appreciated too! -

django ModelForm validation failing with newly created objects

Having trouble with the authentication process of logging in Facebook from my Django project
I am new to Django and I wanted to build a Django application that could allow users to log in using Facebook, so I have followed every step listed in this tutorial https://www.digitalocean.com/community/tutorials/django-authentication-with-facebook-instagram-and-linkedin Despite following the same step, I still getting errors after providing my password and click on the continue button.

Displaying images blobs on Django html templates using SaS token

Is there a way to extend django's handling of bulk data that is returned from the DB?
I have implemented a custom field with a from_db_value() method and get_db_prep_value() method. These effectively act as a layer between the caller and the data in the database, and it works well. I used it to implement a lookup the data in a secondary store. The problem is that for bulk data (e.g. list(MyModel.objects.all())), my function from_db_value() will get called O(n) times, which means that if it does something costly (e.g. my use case of lookup in a secondary store) it's really inefficient. What is the best way to "capture" bulk calls and do the conversion in one go? -
Making pagination work with multiple tables in Django
I have a html page in which you can change the table displayed based on the value of a select box. The pagination does not seem to work as intended. When the page is initially loaded the pagination works fine however when changing the the table and trying to go to the next page it loads the second page of the default table. Here are the relevant parts in the template: <h1 id="tableHeader">Users</h1> <div id="template"> {% include user_table %} </div> <select class="form-select" name="view_select" id="view_select" onchange="loadTable()"> <option value="1" selected>Users</option> <option value="2">Categories</option> </select> The JavaScript function loadTable: function loadTable() { var select_value = document.getElementById("view_select").value; if (select_value == 1) { var url = "{% url 'user_table' %}"; } else if (select_value == 2) { var url = "{% url 'category_table' %}"; } else { return; } $.ajax({ url: url, type: "GET", success: function(response) { $("#template").html(response); } }); } The url.py file: path('user_table/', views.user_table, name='user_table'), path('category_table/', views.category_table, name='category_table'), The relevant views: def admin_dashboard(request): if (request.user.is_staff == False) and (request.user.is_superuser == False): return redirect('landing_page') else: if request.method == 'POST': # IF CREATE USER BUTTON CLICKED if 'create_user' in request.POST: form = CreateUserForm(request.POST) if form.is_valid(): user = form.save() return redirect('admin_dashboard') # IF CREATE CATEGORY BUTTON CLICKED … -

Javascript for dynamically revealing Django formset forms
I'm trying to add/remove forms from formsets dynamically on button press. I am looking at an older example for JS to perform this action but I have multiple formsets but when I delete all of the forms for one of the formsets, obviously the addForm command no longer works as there are no forms to clone. That being said, I think a functional method would be to start with a hidden form and then copy the hidden form and display that form on demand. I just don't know how exactly to do that. Ideally, I'd like to not show any forms until the button press but not certain about how to do it. My current setup is shown below. HTML: <div class="selection"> <div class="forms"> <!-- {% for dict in formset.errors %} {% for error in dict.values %} {{ error }} {% endfor %} {% endfor %} --> <form id="general-formset" method="POST"> {% csrf_token %} {{ generalFormset.management_form }} {% for form in generalFormset %} <div class="formset"> {{ form.as_table }} <button id="remove-form" type="button" onclick="removeForm(this)" display="None">Remove Constraint</button> </div> {% endfor %} <button id="add-form" type="button" onclick="addForm(this)">Add Constraint</button> </form> <form id="specific-formset" method="POST"> {% csrf_token %} {{ specificFormset.management_form }} {% for form in specificFormset %} <div class="formset"> … -
Why is the drf login page showing me an error of wrong credentials even though i'm using the right credentials?
I'm working on a DRF project and was working on the Custom User Model. I can launch the server without errors and see all the API endpoints. However, after registering a new user, when I try to log in with the user's credentials, I get the error of giving the wrong email or password. I'm using dj-rest-auth for registering new users. Upon going into the admin, I see the notification of a new user being created, but for some reason, my code isn't letting them log in. Here's my models.py file:- import uuid from django.db import models from django.contrib.auth.models import AbstractUser from django.contrib.auth.models import BaseUserManager # Create your models here. GENDER_CHOICES = [ ('M','Male'), ('F','Female'), ('R','Rather not say'), ] class UserManager(BaseUserManager): def create_user(self,First_name:str,Last_name:str,Email:str,password:str,username:str,is_staff = False,is_superuser = False) -> 'User': if not Email: raise ValueError('User must have an Email') if not First_name: raise ValueError('User must have a First Name') if not Last_name: raise ValueError('User must have a Last Name') user = self.model(Email = self.normalize_email(Email)) user.First_name = First_name user.Last_name = Last_name user.set_password(password) user.username = username user.is_active = True user.is_staff = is_staff user.is_superuser = is_superuser user.save() return user def create_superuser(self,First_name:str,Last_name:str,Email:str,password:str,username:str)-> 'User': user = self.create_user( First_name = First_name, Last_name = Last_name, Email=Email, username=username, password=password, … -
Does django have lazy queries in foreign reverse lookup?
I have this code: def get_percentage_completions(task: Task, date_start: date, date_end: date): result = {} execution_percents = task.execution_percents.all() if execution_percents.exists(): year, week, _ = date_start.isocalendar() task_execution_percent = execution_percents.filter(year__lte=year, week__lte=week) \ .order_by('year', 'week').last() execution_percent = task_execution_percent.percent if task_execution_percent else 0 while date_end >= date_start: year, week, _ = date_start.isocalendar() if execution_percents.filter(year=year, week=week).exists(): task_execution_percent = execution_percents.filter(year=year, week=week).first() execution_percent = task_execution_percent.percent key = f"{year}_{week}" result[key] = round(execution_percent) date_start += timedelta(days=7) return result I get related objects from my model "Task". I thoght I hit to db once on second line when I define execution_persents variable, but actually my debug toolbar decrease amount of queries when I comment all lines after execution_persents variable. It means I hit to db inside while loop. Can I hit to db only once on the second line?
