Django save multiple foreign keys to database with multiple upload - django

Question

I am a newbie in Django and I am looking for the best workaround on how to deal with this problem.
I have these 3 Models:
class Rigs(models.Model):
name = models.CharField(max_length=30)
featured_img = models.ImageField(upload_to='images/')
created_at = models.DateTimeField(auto_now_add=True)
def __str__(self):
return self.name
class Gallery(models.Model):
rigs = models.ForeignKey(Rigs, on_delete=models.CASCADE, related_name='galleries')
file = models.ImageField(upload_to='images/')
def __str__(self):
return self.name
class Specs(models.Model):
cpu = models.CharField(max_length=50)
motherboard = models.CharField(max_length=50)
rigs = models.ForeignKey(Rigs, on_delete=models.CASCADE)
def __str__(self):
return self.cpu
I am using this library for the multi-uploading of images (https://github.com/Chive/django-multiupload), so basically I structured my Forms similar to what the document states:
class SpecsForm(forms.ModelForm):
class Meta:
model = Specs
fields = ('rigs', 'motherboard')
class RigForm(forms.ModelForm):
class Meta:
model = Rigs
fields = ('name','featured_img')
gallery_image = MultiMediaField(
min_num=1,
max_num=3,
max_file_size=1024*1024*5,
media_type='image'
)
def save(self, commit=True):
instance = super(RigForm, self).save(commit)
for each in self.cleaned_data['gallery_image']:
Gallery.objects.create(file=each, rigs=instance)
return instance
As well as my Views:
class newrig(CreateView):
model = Rigs
form_class = RigForm
template_name = 'flexrigapp/newrig.html'
success_url = '?success'
My problem is that I couldn't figure out how to include the SpecsForm on my HTML Form as well as save it on my database with the correct Foreign Key.
I have already tried transferring this one on my views with some changes but still no good.
def save(self, commit=True):
instance = super(RigForm, self).save(commit)
for each in self.cleaned_data['gallery_image']:
Gallery.objects.create(file=each, rigs=instance)
return instance
Also, I tried a function based views instead of class based but the problem is that the multi-uploading validation doesn't work on this approach of mine or maybe my code is not correct.
The expected result is that data should be saved on its respective databases (Rigs, Specs, Gallery) with the proper Foreign key on the Specs and Gallery. Right now, I can only save the Rigs and Gallery.
This is Django 2.2.4, by the way.
UPDATE
I tried updating my Views to Function-Based View just like what #dirkgroten suggested.
def newrig(request):
if request.method == 'POST':
rig_form = RigForm(request.POST, request.FILES, prefix="rigs")
specs_form = SpecsForm(request.POST, prefix="specs")
if rig_form.is_valid() and specs_form.is_valid():
rigs = rig_form.save()
specs = specs_form.save(commit=False)
specs.rigs = rigs
specs.save()
return HttpResponseRedirect("?success")
else:
rig_form = RigForm(prefix="rigs")
specs_form = SpecsForm(prefix="specs")
return render(request, "flexrigapp/newrig.html", {'rig_form': rig_form,'specs_form': specs_form,})
No data is being saved on the database now. No error logs.
