Using select2 on custom django forms and model forms
While reading the documentation of https://github.com/applegrew/django-select2, there is a note: "Django's admin comes with builtin support for Select2 since version 2.0 via the autocomplete_fields feature." I was able to enable autocomplete_fields for my admin site forms. The question is, is there any built-in functionality for custom and model forms where I need not install any third-party libraries? Is there any way I can leverage already included select2 functionality (for admin site) for model forms? I tried searching the same on google but could not find any documentation. This code is irrelevant but I thought my question should have some code so. models.py from django.db import models class Market(models.Model): CHOICES = [ ('IN', 'India'), ('US', 'United States'), ('EP', 'Europe'), ('JP', 'Japan') ] name = models.CharField(max_length=3, choices=CHOICES, blank=True, unique=True) class Product(models.Model): markets = models.ManyToManyField(Market) admin.py from django.contrib import admin class MarketAdmin(admin.ModelAdmin): search_fields = ['name'] class ProductAdmin(MarkdownxModelAdmin): autocomplete_fields = ['market'] forms.py from django.forms import ModelForm class ProductForm(ModelForm): class Meta: model = Product fields = ['markets'] -
Django REST Framework : ManyToMany relationship
I'm currently working on a Django project, I'm new at this and it's difficult to find clear documentation about this. My issue is very simple, I want at the creation of my model, automatically associate another model through a ManyToMany relationship. Here goes the code : Serializer : class FavoriteSerializer(serializers.ModelSerializer): estates = EstateSerializer(read_only=True, many=True) class Meta: model = Favorite fields = ['uuid', 'title', 'estates'] def create(self, validated_data): instance = super(FavoriteSerializer, self).create(validated_data) instance.save() return instance ViewSet : class MyFavoriteEstatesListViewSet(viewsets.ModelViewSet): serializer_class = FavoriteSerializer def get_queryset(self): return Favorite.objects.filter(users__id=self.request.user.id) I'm currently sending something like this through a POST : {"title": "some title", "estate_uuid": "XXX"} I just wanted to instantiate my Estate model with the UUID I just sent and adding it with favorite.estates.add(estate) How can I achieve this ? Thanks for your help ! -

How do I model a team registration system in Django once a user logs in and get it to show on the homepage?
I'm trying to create a hackathon management system using Django 3. I've created an app 'accounts' which takes care of normal user registration to my website (name,email etc). In the backend django interface, I add these registered users manually to a list of hackathons I've created. The homepage of my website shows the list of hackathons and the people registered for them. Now what I want is for this logged in user to click on say, a register button on the homepage's sidebar which allows him/her to add names of his/her teammates, select a hackathon thereby registering themselves. Similar to what happened previously, I'd like the team names and details to show up on the homepage. How do I do this? These are the contents of my models.py files from the 'accounts' app: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) # social github = models.CharField(max_length=30, null=True, blank=True) linkedin = models.CharField(max_length=30, null=True, blank=True) #others = models.CharField(max_length=30, null=True, blank=True) # tags TAGS = [ ('New', 'Newbie'), ('Developer', 'Developer'), ('Business', 'Business'), ('Designer', 'Designer'), ] phone = models.CharField(max_length=10, blank=True, default='') skillset = models.CharField(max_length=200, blank=True, default='') tags = models.CharField(max_length=15, default='New', choices=TAGS) bio = models.TextField(max_length=900, blank=True, default='') def __str__(self): return self.user.username # signal - every time a … -
Django filter for all items which contain at least one null value
An answer elsewhere on SO provides the Postgresql NOT(<table> IS NOT NULL) query as an option to find all rows in a table containing one or more null values. How would one apply this query in the Django ORM without writing raw SQL? Or is this a case where raw SQL is required? I couldn't find an example of such as query in the latest Django docs. For reference, the example shown in the linked answer is as follows: SELECT * FROM t; ┌────────┬────────┐ │ f1 │ f2 │ ├────────┼────────┤ │ (null) │ 1 │ │ 2 │ (null) │ │ (null) │ (null) │ │ 3 │ 4 │ └────────┴────────┘ (4 rows) SELECT * FROM t WHERE NOT (t IS NOT NULL); ┌────────┬────────┐ │ f1 │ f2 │ ├────────┼────────┤ │ (null) │ 1 │ │ 2 │ (null) │ │ (null) │ (null) │ └────────┴────────┘ (3 rows) -

Django Form DateInput with widget in update: loosing the initial value
I need a DateInput field in a ModelForm with the default HTML datepicker (I'm not using 3rd party libraries). Since the DateInput is rendered with <input type = "text"> by default, the datepicker is missing (it comes for free with <input type = "date">) I've found some examples explaining how to change the input type by handling widget parameters (below the code I've done so far) The issue I have the datepicker working correctly but in "update mode" when passing initial date value to the form (see view part), the date remains empty in the HTML. I've tried to find the cause and it seems that the 'type': 'date' part in the widget customization is clearing the initial value is some way; in fact, removing it, the initial value date is displayed again, but I loose the datepicker of course. In the view the date is passed with a valid value I also found another similar unanswered question where the field was declared as class DateInput(forms.DateInput): input_type = 'date' date_effet = forms.DateField(widget=forms.DateInput(format='%d-%m-%Y'), label='Date effet') the problem still remains My code model.py class TimesheetItem(models.Model): date = models.DateField() description = models.CharField(max_length=100) # many other fields here form.py class TimesheetItemForm(forms.ModelForm): def __init__(self, *args, … -

With Django, can I reset primary key of all existing records?
Say I have a model Client: class Client(models.Model): name = ... address = ... And I imported a list of 1000+ clients to the model, with django-import-export. It worked like a charm. However, the ids (primary key) of the records aren't start from 1. It seems that by importing the clients, ids from 1 to 1000+ are used by django-import-export, and the imported client instances using id from 1000+. No harm but not beautiful. So is it possible to reset all the records' ids from 1? Does sqlsequencereset work in this situation? -
Django Rest Framework + Django CAS
I've been tasked with adding CAS authentication to an existing Django app which uses the Django Rest Framework. Using django-cas library I'm able to authenticate via CAS to the admin features of the Django framework, but I'm not sure how to go about authenticating the Django rest framework app via CAS; it's still authenticating via some custom authentication logic that the original developers added. If anyone has any insight or experience with this it would be much appreciated. -
Django model React
I'm trying some Django + React stuff and I'm a bit confused with the particular role of Django model in this scheme. As I can understand Django model provide smooth way to create some typical forms by users of the site (please correct me). And I can't feel the edge of what should be hardcoded and what I need to store in model. In case of React (I'm trying to connect react with django through api via djangorestframework) should I create a model for Header? And store bg image with it and my slogans. I feel it's should be purely in frontend. But next section with 3 typical screens (they will be listed horizontally and swap each other). They are just copy of each other with different data (title, bg, fg, text, link), for me it seems closer to model usage. But model initially empty and if I want to get this data from model I firstly need to somehow store this data to model. ofc I searched this info widely but so far can't create clear understanding by myself. Thanks ) -

Refresh displayed data on click in Django app
I am using Ajax to get the appropriate url that displays orders based on the date that was clicked in a calendar. This works, but every time user clicks on a date, the content duplicates, not removing the previous display. https://i.stack.imgur.com/nEdWg.png I would like the content to refresh, when the user clicks on a date again. How would I do that? I was searching for a "Jquery refresh DIV", and stumbled upon location.reload(), ajax.reload(), jquery load method, and similar solutions. I tried implementing these, but not sure if they are the right solution for my case. Here is my code. Please let me know if I should post anything else. Help appreciated. .js $(function () { var $archive = $('#orders-per-day'); $(".day-click").click(function (event) { event.preventDefault(); var day = $(this)[0].innerText; var month = $(".month")[0].innerText.substring(0, 3); var year = $(".month")[0].innerText.substr(-4); console.log(year); $.ajax({ type: 'GET', url: `/ocal/date/${year}/${month}/${day}/`, success: function (data) { $archive.append(data); } }) }); }); html template for showing the orders of one day {% extends 'ocal/base.html' %} {% block content %} <h1>Orders for {{ day }}</h1> <ul> {% if object_list %} {% for order in object_list %} <li> <a href="/ocal/{{ order.id }}/detail">Order {{ order.id }} </a> {{ order.status_str }} </li> {% endfor … -
Django Dynamic form for manytomany relationship
