image upload in a template - django

Question

My issue is if I upload from admin an image it works fine but if I want to add an image from my template, it seems that my image does not updload.
It is weird as in the request.Post form, path of my image is present.
I've no message of error...
this is my model:
class Listing(models.Model):
title = models.CharField('Title',max_length=64, blank=False)
description = models.TextField('Descritpion', blank=False)
Creation_date = models.DateField(auto_now_add=True)
enddate= models.DateField('Ending Date', blank=False)
category = models.ForeignKey(Category, on_delete=models.CASCADE, related_name="category")
initialBid = models.DecimalField('Bid', max_digits=12, decimal_places=2, blank=False)
photo = ResizedImageField(size=[300, 150], upload_to='images/', default='images/default.jpg')
active = models.BooleanField('Active', default=True)
author = models.ForeignKey(User, on_delete=models.CASCADE, related_name="author")
def __str__(self):
return f"{self.id} : {self.title} {self.initialBid} {self.Creation_date}"
def save(self, *args, **kwargs):
# Check how the current ending date is after created date,
d1 = self.Creation_date
d2 = self.enddate
if d2 <= d1:
raise ValueError("End date must be a day after today")
super(Listing, self).save(*args, **kwargs)
my form:
class NewListingForm(forms.ModelForm):
enddate = forms.DateField(label='Date of auction End', widget=forms.DateInput(format = '%d/%m/%Y'),
input_formats=('%d/%m/%Y',))
def __init__(self, *args, **kwargs):
self._newly_created = kwargs.get('instance') is None
self.Creation_date = datetime.now()
super().__init__(*args, **kwargs)
class Meta:
model = Listing
fields = ('title','description','enddate','category','initialBid','photo','active')
my template:
<h2>{% if not form.instance.pk %}Create listing {% else %} Edit {% endif %}</h2>
<form id="create-edit-client" class="form-horizontal" action="" method="post" accept-charset="utf-8" enctype="multipart/form-data">

thanks for help

Answer 1

form = NewListingForm(request.POST, request.FILES,instance=Listing.objects.get(pk=listing_id))

Answer 2

for getting the images or files you need pass another request that it's called request.FILES, so:
#login_required
def editlisting(request, listing_id):
obj = Listing.objects.filter(pk=listing_id).first()
if obj is None:
return render(request, "errors/404.html", {
"entryTitle": listing_id
})
else:
form = NewListingForm(instance=Listing.objects.get(pk=listing_id))
modification=True # used in template to check if modification are
allowed
# read only form if not author
user = request.user.id
if obj.author.id != user:
modification=False
# manage save
if request.method == "POST":
form = NewListingForm(request.POST, request.FILES,
instance=Listing.objects.get(pk=listing_id))
if form.is_valid():
form.save()
messages.success(request, 'listing saved') # message for
inform user of success - See messages in html file
return HttpResponseRedirect(reverse("index"))
# check if in wishes on get
wishbool=False
wish = Wishing.objects.filter(item=listing_id,
follower=request.user.id).first()
if wish is not None:
wishbool = True
return render(request, 'auctions/newListing.html', {
"form": form,
"existing": True,
'title': "Edit Listing",
"wishing": wishbool,
"modification":modification
})
