AddAnotherWidgets not filled

[Joris-Pieters]

Thanks for your great work.

I'm not sure if this is a bug or a mistake on my side (more likely), but when I load an existing instance in a form the AddAnotherWidgets are not filled with the current value. The "normal" fields are filled however.

I based my code on the example app, but that only has a submit option and does not let you load an existing instance.

Any idea what could be going wrong?

Can you please post some code so it’s easier to understand.

In my case I have a model "project" that contains a CharField "title", and a ForeignKey "company". For "company" I want to use the AddAnotherWidget so the user can add companies (there's more to a "project" of course, but I try to limit the code to only what is relevant):

models:

from django.db import models

class Project(models.Model):

    title = models.CharField(max_length = 255)
    company = models.ForeignKey(Company, on_delete = models.DO_NOTHING, blank = True, null = True)

    def __str__(self):
        if self.start_date is None:
            return f"{self.company.__str__()}: {self.title.__str__()} "
        else:
            return f"{self.company.__str__()}: {self.title.__str__()} ({str(self.start_date.year)})"

    class Meta:
        ordering = [Lower('company'), Lower('title')]

class Company(models.Model):

    name = models.CharField(max_length = 255, unique = True, blank = False)

    def __str__(self):
        return self.name

    class Meta:
        verbose_name_plural = "Companies"
        ordering = [Lower('name')]      

views (project_view is function based as this is what I knew when I started while view for company is class based as this is a requirement for AddAnother if I understood well):

from django.shortcuts import render
from django.http import HttpResponse
from django.contrib import messages
from django_addanother.views import CreatePopupMixin

from ..forms import *
from ..models import *

def project_view(request, pk):

    if request.user.is_authenticated:

        project = Project.objects.get(pk = pk)
        request.user.last_watched_project = pk
        request.user.save()

        if request.method == 'GET':        
            form = ProjectForm(initial = project.__dict__)
            context = {
                'form': form,
                'jquery': 'admin/js/vendor/jquery/jquery.js',
            }
            return render(request, "main/project.html", context)

        if request.method == 'POST':
            form = ProjectForm(request.POST)
            context = {
                'form': form,
                'jquery': 'admin/js/vendor/jquery/jquery.js',
            }

            if not request.user.is_superuser:
                messages.error(request, "You do not have the proper rights to change this.")
                return render(request, "main/project.html", context)

            if form.is_valid():
                project = form.save()
                messages.success(request, "Project saved.")
                return render(request, "main/projects.html")
            else:
                messages.error(request, "One or more required fields are empty.")
                return render(request, "main/project.html", context)

class CreateCompany(CreatePopupMixin, generic.CreateView):

    model = Company
    fields = ['name']

forms:

from django import forms
from django_addanother.widgets import AddAnotherWidgetWrapper

from main.models import *

class ProjectForm(forms.ModelForm):

     class Meta:
        model = Project
        fields = ('title', 'company')
        widgets = {
            'company': AddAnotherWidgetWrapper(
                forms.Select(),
                '/company',
            ),
        }

class CompanyForm(forms.ModelForm):

    class Meta:
        model = Project
        fields = '__all__'

urls:

from django.conf.urls.static import static
from django.urls import path

from references import settings
from . import views

app_name = 'main'

urlpatterns = [
    path("", views.home, name = "home"),
    path("project/<int:pk>/",  views.project_view, name = "project_view"),    
    path("company", views.company_view.CreateCompany.as_view(), name = "company_view"),
    ] + static(settings.MEDIA_URL, document_root = settings.MEDIA_ROOT)

Problem: Let's say I made a project with name = "first project" and company = "EvilCorp". If I check in admin this is saved properly, even if I created "EvilCorp" on the spot using the AddAnotherWidget (so that is working great!). When I load this project back to a form for editing however the field name correctly contains "first project", while company gives the default value of "------". Same goes for other "classic" widgets versus AddAnotherWidgets.

Thanks for your support!

My bad, this wasn't an issue with AddAnotherWidgets, but my very own mistake. in the views form = ProjectForm(initial = project.__dict__) should be form = ProjectForm(instance = project)
