Django: Cannot assign "'2'": "Issues.reporter" must be a "User" instance
I am working on a simple "issue tracking" web application as way to learn more about Django. I am using Django 4.1.4 and Python 3.9.2. I have the following classes in models.py (which may look familiar to people familiar with JIRA): Components Issues IssueStates IssueTypes Priorities Projects Releases Sprints Originally I also had a Users class in models.py but now am trying to switch to using the Django User model. (The User class no longer exists in my models.py) I have been studying the following pages to learn how best to migrate to using the Django Users model. Django Best Practices: Referencing the User Model https://docs.djangoproject.com/en/4.0/topics/auth/customizing/#referencing-the-user-model All of my List/Detail/Create/Delete view classes worked fine with all of the above models until I started working on using the Django User class. -- models.py -- from django.conf import settings class Issues(models.Model): reporter = models.ForeignKey( settings.AUTH_USER_MODEL, on_delete=models.RESTRICT, related_name="reporter_id", ) -- issues.py -- class CreateUpdateIssueForm(forms.ModelForm): ... class IssueCreateView(LoginRequiredMixin, PermissionRequiredMixin, generic.CreateView): ... form_class = CreateUpdateIssueForm When I try to create a new Issue, the "new Issue" form is displayed normally, but when I save the form I get a Django error with a stack trace I don't understand because it does not have a reference … -
Trying to apply CRUD functionality to python project
So I'm building a real estate website for school. And one of the requirements is to have CRUD functionality on the front end for admins. But before i knew that i created in the backend admin page, all the fields that need to be filled before a listing can be published. But now i need to display all of the fields i created on the backend admin page to show on the front end. I've tried writing the code to display it but its not really working. Im only seeing the submit button. Im new to coding and stack overflow, so please do let me know if you need anything els from me or if ive done something wrong. these are the fields that should be filled and show up in the front end for realtors to publish, edit and remove a listing: models.py class Listing(models.Model): realtor = models.ForeignKey(Realtor, on_delete=models.DO_NOTHING) title = models.CharField(max_length=200) address = models.CharField(max_length=200) city = models.CharField(max_length=100) state = models.CharField(max_length=100) zipcode = models.CharField(max_length=20) description = models.TextField(blank=True) price = models.IntegerField() bedrooms = models.IntegerField() bathrooms = models.DecimalField(max_digits=2, decimal_places=1) garage = models.IntegerField(default=0) sqft = models.IntegerField() photo_main = models.ImageField(upload_to='photos/%Y/%m/%d/') photo_1 = models.ImageField(upload_to='photos/%Y/%m/%d/', blank=True) photo_2 = models.ImageField(upload_to='photos/%Y/%m/%d/', blank=True) photo_3 = models.ImageField(upload_to='photos/%Y/%m/%d/', blank=True) photo_4 … -

Dynamically adding a form to a Django formset with empty_formset value
I am sorry for my poor English. I'm going to implement it by referring to Dynamically adding a form to a Django formset and Add row dynamically in django formset It works! But I want to duplicate the empty_form value and add it to the form I want to add. I tried: <h3>My Services</h3> {{ serviceFormset.management_form }} <div id="form_set"> {% for form in serviceFormset.forms %} <table class='no_error'> {{ form.as_table }} </table> {% endfor %} </div> <input type="button" value="Add More" id="add_more"> <div id="empty_form" style="display:none"> <table class='no_error'> {{ serviceFormset.empty_form.as_table }} </table> </div> <script> $('#add_more').click(function() { var form_idx = $('#id_form-TOTAL_FORMS').val(); $newform = $("#empty_form").clone(true,true) $("#form_set").append($newform.html().replace(/__prefix__/g, form_idx)); $('#id_form-TOTAL_FORMS').val(parseInt(form_idx) + 1); }); </script> But it doesn't work. What can I do? thanks in advance. -

Django ecommerce view that allows add_cart with same product_id but different product_options
I am writing a django ecommerce app that has multiple product options that can be optionally added to the same productid. I am having issues getting the view to recognize the same product with differing product options as separate cart items. I am getting it to work about half the time but only if a productid comes through with no options at all first then a follow on item with added options isnt an issue. If you attempt to add a bare product with no options into the cart with an existing same product id with options it either throws an error code or adds the options to the existing cart item and increments it up views.py def add_cart(request, product_id, quantity=1): product = Product.objects.get(id = product_id) # get the product product_options= request.POST.getlist('option')#gets selected product options # try: cart = Cart.objects.get(cart_id=_cart_id(request)) # get the cart using the cart_id present in the session except Cart.DoesNotExist: cart = Cart.objects.create( cart_id = _cart_id(request) ) cart.save()#saves new cart if needed to be created try: cart = Cart.objects.get(cart_id=_cart_id(request)) # get the cart using the cart_id present in the session except Cart.DoesNotExist: cart = Cart.objects.create( cart_id = _cart_id(request) ) cart.save()#saves new cart if needed to be created … -

I'm trying to use django to build a phase timer app for myself. I want a timer to run for each phase, then reset to zero and run for the next phase for n-cycles. I've tried asking 'Friend computer' for help but am still struggling. Here's the model. from django.db import models # Create your models here. class Cycle(models.Model): name = models.CharField(max_length=100) instructions = models.TextField() phase_1_time = models.PositiveIntegerField() phase_1_hold_time = models.PositiveIntegerField() phase_2_time = models.PositiveIntegerField() phase_2_hold_time = models.PositiveIntegerField() recovery_time = models.PositiveIntegerField() max_cycles = models.PositiveIntegerField() def __str__(self): return self.name And here's the view ''' View for the cycle app.''' from django.shortcuts import render from .models import Cycle def exercise_list(request): exercises = Cycle.objects.all() return render(request, 'cycles/exercise_list.html', {'exercises': exercises}) def exercise_detail(request, exercise_id): exercise = Cycle.objects.get(id=exercise_id) phase_1_duration = exercise.phase_1_time phase_1_pause_duration = exercise.phase_1_pause_time phase_2_duration = exercise.phase_2_time phase_2_pause_duration = exercise.phase_2_pause_time recovery = exercise.recovery_time max_cycles = exercise.max_cycles return render(request, 'cycles/exercise_detail.html', { 'exercise': exercise, 'phase_1_duration': phase_1_duration, 'phase_1_pause_duration': phase_1_pause_duration, 'phase_2_duration': phase_2_duration, 'phase_2_pause_duration': phase_2_pause_duration, 'recovery': recovery, 'max_cycles': max_cycles, and the html <html> <head> <title>{{exercise.name}}</title> </head> <body> <h1>{{ exercise.name }}</h1> <p>Instructions: {{ exercise.instructions }}</p> <p>Phase 1 Time: {{ exercise.Phase_1_time }}</p> <p>Phase 1 pause Time: {{ exercise.phase_1_pause_time }}</p> <p>Phase2 Time: {{ exercise.Phase_2_time }}</p> <p>Phase 2 pause Time: {{ exercise.phase_2_pause_time }}</p> <p>Long pause Time: … -

Is there a way to hook into DRF ListAPIView to make additional queries for all instances at once?
I am using the Django REST Framework ListAPIView class to represent a collection of model instances and handle pagination automatically. It's great when you have all the data in the queryset or can grab related data with select_related/prefetch_related to add to the same queryset but when you need to gather more data for each model instance in a different way because there is no direct db relationship, you end up making queries for each instance in the serializer, resulting in a n+1 queries problem. Is there a way to hook into ListAPIView at a point where all the instances of the current page being returned are known so that more processing/queries can be done at once to fetch the additional data for all instances and add it to the response? class Gift(models.Models): ... class SearchList(ListAPIView): serializer_class = SearchGiftSerializer pagination_class = StandardResultsSetPagination def get_queryset(self): return Gift.objects.all()
