Get data from clicked elements Django
I have a page where User can select people to add in his team. One side of the page is the list of the people to select. When user click Add to the team, it goes to the right side where we have the list of the selected people. I don't understand how I can get the data on the selected side from the view in django.. For example on the left: <div class="card-body" id="team-list"> <p class="card-text">Select today's teammates:</p> <ul class="list-group list-group-flush"> {% for tech in techs %} <li class="list-group-item"> <span class="name" name="{{tech.id}}">{{tech}}</span> <span class="move" style="float: right;">Add to the team</span> </li> {% endfor %} and on the right: <div class="card-body" id="selected-list"> <h3 class="title">You have selected the following teammates for today: </h3> <ul class="list-group list-group-flush" style="list-style-type: none;"> </ul> </div> The click is handled by a little js click event like this: var selected = document.querySelector('#selected-list ul'); var team = document.querySelector('#team-list ul'); function clickHandlerTeam(e){ if(e.target.classList.contains('move')){ if (e.target.textContent == 'Add to the team'){ console.log('changing add'); e.target.textContent ='Remove from the team'; selected.appendChild(e.target.parentNode); } else { console.log('changing remove'); e.target.textContent = 'Add to the team'; team.appendChild(e.target.parentNode); } console.log('****************'); } return; } Thanks for your help -

i have two models fed into a signals.py file with two post_save signals each referencing two different models with a common sender, User, when I create a user, for example, a doctor, I discovered a user is saved with both groups, these groups are doctor and patient, I want a situation where if I create a user, a user which is related to a model(One To ONE relationship) is assigned only one group out of the two i.e User saved to doctor group not user having patient and doctor assigned to it, I also want a user details on creation saved to the associated model, I only get user.username saved to a particular model. i also have issues updating my patient profile page but the doctor's profile page updates, the patient doesn't, please what am I doing wrong, would appreciate your inputs this is my signals.py from django.db.models.signals import post_save from .models import * from django.contrib.auth.models import User from django.contrib.auth.models import Group def create_profile(sender, instance, created, **kwargs): if created: group = Group.objects.get(name='doctor') instance.groups.add(group) Doctor.objects.create( user=instance, name=instance.username, ) print("Profile Created For Doctor") post_save.connect(create_profile, sender=User) def create_patient_profile(sender, instance, created, **kwargs) if created: group_patient = Group.objects.get(name='patient'): instance.groups.add(group_patient) Patient.objects.create( user_p=instance, name=instance.username, ) print("Profile Created … -
Simple database insert and delete via Ajax in Django application
I'm working on a Django application that involves various people, companies, and products. I'd like to include the ability for logged in users to "favorite" any number of those people, companies, and products. I'm a pretty new Django developer and my knowledge of Javascript is scant, so I'm struggling to apply the existing Django/Ajax tutorials to my situation. Here's what I have so far. I'm going to include just the bits about favoriting a person since I presume that solution for favoriting companies and products will be virtually identical. # models.py (relevant tables only) class Person(models.Model): first_name = models.CharField(max_length=50) middle_name = models.CharField(max_length=50, blank=True) # many other irrelevant fields omitted class CustomUser(AbstractUser): fav_people = models.ManyToManyField(Person, through='FavoritePerson', through_fields=('user', 'person'), related_name='users', ) fav_companies = models.ManyToManyField(Company, through='FavoriteCompany', through_fields=('user', 'company'), related_name='users', ) fav_products = models.ManyToManyField(Product, through='FavoriteProduct', through_fields=('user', 'product'), related_name='users', ) class Meta: verbose_name_plural = 'Custom Users' def __str__(self): if self.first_name and self.last_name: return f"{self.first_name} {self.last_name}" else: return f"{self.username}" class FavoritePerson(models.Model): user = models.ForeignKey(CustomUser, on_delete=models.CASCADE, related_name='favorite_people' ) person = models.ForeignKey(Person, on_delete=models.CASCADE, null=True, blank=True, related_name='favorite_people', ) created = models.DateTimeField(auto_now_add=True) class Meta: verbose_name_plural = 'Favorited People' def __str__(self): return f"{self.user} - {self.person}" Here's the relevant portion of my template where it displays a star outline if the person … -

Django show model form in html with 2 foreign key as column and row
I want to display a form of this class class Cost(models.Model): supply = models.ForeignKey(Supply, on_delete=models.CASCADE) demand = models.ForeignKey(Demand, on_delete=models.CASCADE) cost = models.IntegerField(default=0) Supply and demand is a city that only have name and amount attributes. It's a table for transportation problem. I've tried using formset but it don't allow me to save(not valid), using ordinary form as array gave me the same result(i'm a new/moron i don't mind getting an offensive comments as long as i found the answer). I also tried using django tables2 but i don't find how to set supply attribute as row. I want it to display like this: City | A | B | C | Supply D | 1 | 2 | 3 | 12 E | 4 | 5 | 6 | 6 Demand | 5 | 6 | 7 | How can i display my models with cost (1 , 2, 3, 4, 5, 6) as an editable form? -
Can you have two Google Cloud Projects that talk to the same Cloud SQL Database?
I have just created a Project in Google Cloud, and attached a Cloud SQL Database instance to that project. I was able to deploy a Django app that is connected to that DB just fine. However, I would like to create a separate Django app/Project that is attached to the same Cloud SQL Database that my first Django app is attached to. Is this possible? One Django app is responsible for web scraping and supplying constant data to the database while my second Django app (the one I have already deployed) analyzes and returns json on that data. It would be advantageous to separate the two apps because if I ever needed to revise my web scraping algorithm, the whole app would not be down. -
Django href repeats URL in searchbar
This is a really basic question but I'm relatively new to django. I have a navigation bar: <nav> <ul> <li> <a href="transfer"> Home </a> </li> <li> <a href="transfer/upload"> Upload </a> </li> <li> <a href="transfer/download"> Download </a> </li> </ul> </nav> So for example when I am at my localhost:8000/transfer and click the "upload" button, I get redirected successfully to localhost:8000/transfer/upload, but afteer that when I click "home" for example, I'm redirected to localhost:8000/transfer/transfer (if I click download from upload, it is localhost:8000/transfer/transfer/download). I've tried modifying my hrefs to not include "transfer/" but then I run into an invalid page when I click a button the first time. urls.py from django.urls import path from . import views urlpatterns = [ path('', views.index, name='index'), path('/upload', views.upload, name='upload'), path('/download', views.download, name='download') ] What can I do to fix this? -

Django 3.0: inline formset with multiple models not updating
I have been blocked on this for a while so thought I'd ask: I have a simplified example below, but essentially I have 3 models (one parent, two children) all combined in one form (formset and two inline formsets). My issue is: POSTing form for artist_new, it successfully writes to DB etc. All good. GET for artist_edit works, but any saves (POST, either with or without edits) do not save to DB. Currently it redirects back to the edit form, with the edits pre-populated in the form (so form data is being passed correctly, i.e. prefixes etc.?) My thought is that it is a view issue, my debugging has brought me to the fact that in the function views.artist_edit book_formset.is_valid() and music_formset.is_valid() both return False. Interestingly, all of the above was working with just one inline formset. Any help much appreciated. # models.py from django.db import models class Artist(models.Model): name = models.CharField(max_length=100) class Book(models.Model): artist = models.ForeignKey(Artist, on_delete=models.CASCADE) title = models.CharField(max_length=100) class Music(models.Model): artist = models.ForeignKey(Artist, on_delete=models.CASCADE) title = models.CharField(max_length=100) album = models.CharField(max_length=100) # views.py from django.utils import timezone from django.shortcuts import redirect, render, get_object_or_404 from django.forms import inlineformset_factory from .models import Artist, Book, Music from .forms import ArtistForm, BookForm, … -

Django model for different model
I'm learning Django and I'm trying to make a sort of wiki type app. In this wiki there are different type of models: Characters, Items, Spells and Adventures. Each model has some fields that are the same (like name, author, date_created, etc.) and some that are unique to the model, like duration for adventures, alignment for characters, etc. The problem that I have is that if they are different models then every time I want to make something that is common to all of the models (like being able to like, favorite, create, edit, etc.) then I have to code for each model individually. Is there a way of creating a sort of Content model that contains every character, item, spell and adventure so that every time I want to make a form or a function I just make a Content form or Content function? -

Can Users have other Users in a Relationship in Django?
So, I am fairly new to Django and I know there is just one User type. I am wondering what is the best way for me to go about setting up my models. My site needs 4 different types of users: admins (including superuser), teachers, students, parents. I want only admin to be able to use the built in admin UI. I want teachers to have some admin features but only on frontend UI. So far I have extended AbstractBaseUser and BaseUserManager to create users that can be assigned the 4 roles mentioned above and a few different things. They are working and I can manage authorization of page views with them, but this is just scratching the surface of what I hope to do. But how do I manage this when I want a teacher to have many students in a class and only see those students when they login? I want these students to be assigned to teacher by the admin and then allow the teacher to have some permissions with the student info. Can I use signals to create a Teacher model that belongs to aUser with a role of teacher and that same Teacher model has_many``Students. … -

How to update a value from table accessed via foreign key django ORM

So I have tried accessing this studentleave.leave.available_leaves-=1 # Tried reducing it by one print(studentleave.leave.available_leaves) #prints as 7 as expected because 8 is default But when I access the same model again, it's value is still 8 (old value) I have tried update and save method on studentleave.leave.update() and studentleave.update() which are basically throwing error because that object has no attribute update How can I save those new values for them.

How to get the number of inserts from a raw INSERT query in Django?
I'm running a fairly large insert into select query in Django, which I do using MyModel.objects.raw(insert_query) But that doesn't do anything since queries seem to only be run when something is taken from it's result.

Migrate project from from Symfony 3 to Django
I have a project in Symfony 3 (SaSS application) relatively large monolith, about 5 years old with more than 150 entities and about 13GB of MySQL database. The truth is that for about a year I have been doing smaller projects in Django and have fallen in love for obvious reasons. Now, before my Symfony application continues to grow, I would like to separate the backend (Django -in process-) from the frontend (Vue-pending-) and I have some doubts about the migration process: I have created some models already in Django but I am not very clear on how to migrate the database so that both applications work on it, since during the duration of the migration process, the two applications will have to coexist in the same database. How would the process be so as not to lose information and that both applications coexist? Thank you
