Django inline forms - django

Question

I have to models, an Article and a Photo. There is a many2many relation between them. I need to design an Admin form that works better for editing them.
I batch upload photos and the Photo models are created. Then when I write the articles, I want to be able to edit the Photo models as an inline form.
When I set it up as described so far, I get an article edit form, with a selector to click on the name of each photo. I would like to have all unassigned photos shown, with a text box for the cutline on each photo and checkbox. When I put a checkbox and save the article the pictures are associated with that article. I also need to save the updated Photo objects with the text under each photo.
Suggestions for how I should go about this?
Models.py
class Photo(models.Model):
cutline = models.CharField("Cutline", max_length = 1012, null = True)
uploadDate = models.DateField()
imagefile = models.FileField(upload_to=user_directory_path, max_length=250,
class Articles(models.Model):
pictures = models.ManyToManyField(Photo, related_name='article', blank=True)
title = models.CharField("Title", max_length = 255)
story = models.TextField("Article")
Forms.py
from django import forms
from django.forms import BaseInlineFormSet
from django.forms.formsets import BaseFormSet
from django.forms import ModelForm
from django.db.models import Count, Q
from News.models import Articles, Photo
# Create the form class.
class PhotoIForm(ModelForm):
class Meta:
model = Photo
fields = ['cutline', 'imagefile']
class ArticleForm(ModelForm):
class Meta:
model = Articles
fields = ('title', 'story')
class BasePhotoFormSet(BaseInlineFormSet):
def __init__(self, *args, **kwargs):
super(BasePhotoFormSet, self).__init__(*args, **kwargs)
self.queryset = Photo.objects.annotate(articles_count=Count('article')).filter(articles_count=0)
print(a)
Views.py
#login_required
def article_edit(request):
# Create the formset, specifying the form and formset we want to use.
#PhotoFormSet = modelformset_factory(Photo, formset=BasePhotoFormSet, fields = ('cutline', 'imagefile')) #This doesn't work - seems to fail with the m2m fk
PhotoFormSet = modelformset_factory(Photo, fields = ('cutline', 'imagefile')) # close but it doesn't allow me to set up the initial items and limit photos to ones without assigned articles
article = Articles.objects.get(pk = 2718)
if request.method == 'POST':
article_form = ArticleForm(request.POST, article=article)
photo_formset = PhotoFormSet(request.POST)
if article_form.is_valid() and photo_formset.is_valid():
# Save user info
print("Data is valid save"
else:
article_form = ArticleForm(instance=article)
photo_formset = PhotoFormSet()
context = {
'article_form': article_form,
'photo_formset': article_formset,
}
return render(request, 'News/articleInline.html', context)
