My project has users which have a profile and can edit their profile, one of which is their profile picture. All the user information can be edited or cleared with no problem, except the profile picture. I can edit it, but I cannot clear it.
My models.py:
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
name = models.CharField(max_length=64,blank=True)
profilePic = models.ImageField(blank=True, null=True, upload_to= path_and_rename)
phoneNumber = models.CharField(max_length=12,blank=True)
streetAddress = models.CharField(max_length=64,blank=True)
My forms.py for editing the profile. I also crop the picture based on the user inputs.
class EditProfile(forms.ModelForm):
class Meta:
model = Profile
fields = ("name", "phoneNumber","streetAddress")
labels = {
'phoneNumber': _('Phone Number'),
'streetAddress': _('Street Address and/or Postal Code'),
}
class PhotoForm(forms.ModelForm):
x = forms.FloatField(widget=forms.HiddenInput())
y = forms.FloatField(widget=forms.HiddenInput())
width = forms.FloatField(widget=forms.HiddenInput())
height = forms.FloatField(widget=forms.HiddenInput())
class Meta:
model = Profile
fields = ('profilePic', 'x', 'y', 'width', 'height', )
def save(self):
photo = super(PhotoForm, self).save()
x = self.cleaned_data.get('x')
y = self.cleaned_data.get('y')
w = self.cleaned_data.get('width')
h = self.cleaned_data.get('height')
image = Image.open(photo.profilePic)
cropped_image = image.crop((x, y, w+x, h+y))
resized_image = cropped_image.resize((200, 200), Image.ANTIALIAS)
resized_image.save(photo.profilePic.path)
return photo
Finally, my views.py
def settings(request):
user= request.user
profile = Profile.objects.get(user=user)
if request.method == 'GET':
profile_form = EditProfile(instance=profile)
f1= UserProfile(user=request.user)
photo = PhotoForm(instance= profile)
return render(request, 'listings/settings.html', {'form': f1,'form2': profile_form, 'profilePic':photo})
elif request.method == 'POST':
profile_form = EditProfile(request.POST, request.FILES, instance=profile)
profile_form.save()
photo_form = PhotoForm(request.POST, request.FILES,instance=profile)
if photo_form.is_valid():
photo_form.save()
messages.success(request, 'Your profile has been updated!')
return redirect("/settings")
In my template, I click on clear image button, I even set id_profilePic to "", yet the image remains in the object.
I fixed it. The problem was whenever I try to clear, the x,y,width and height have no values. So it never enters the if statement in views.py
if photo_form.is_valid():
photo_form.save()
I fixed it by giving initial values to them

I have a ModelForm called ListingForm. It takes data from a user but I have stopped some of the model attributes from appearing in this form as I want to feed data to those myself. I have put print statements in my createlisting function in views.py to inspect if the data is actually being saved correctltly, it turns out the data is being saved. Here is the createlisting function:
def create_listing(request):
if request.method == 'POST':
import datetime
listing_form = ListingForm(request.POST, request.FILES)
if listing_form.is_valid():
bid = listing_form.cleaned_data['starting_bid']
print(bid)
listing_form.save(commit=False)
listing_form.user = request.user
print(listing_form.user)
listing_form.date_made = datetime.datetime.today()
listing_form.is_active = True
listing_form.category = Category.objects.get(name=listing_form.cleaned_data['listing_category'])
print(listing_form.category)
#The form is being saved correctly here, and the print statements give the correct results in my terminal
listing_form.save()
Bid.objects.create(user= request.user, value=bid, listing=listing_form.instance)
all_listings = Listing.objects.all()
return render(request, 'auctions/index.html', {
'all_listings': all_listings })
else:
listing_form = ListingForm()
return render(request, 'auctions/createlisting.html',{
'listing_form':listing_form
})
However, when I try to access the data from the model Listing from which the ListingForm is inheriting, the print statements I have put for debugging return the default values for certain fields (category and user) instead of the values I have saved in the ListingForm.
Here is the code that allows me to view the data for the model instance I have created. Mind you, all the other fields have saved correctly except for the fields category and user:
def view_listing(request, listing_id):
listing = Listing.objects.get(pk=listing_id)
#the print results return the default values for the fields category and user instead of the values I saved in my ModelForm
print(listing.category)
print(listing.user)
if request.user == listing.user:
return render(request, 'auctions/view_listing.html', {
'listing': listing,
'flag':True,
'count': listing.bids.all().count()
})
else:
return render(request, 'auctions/view_listing.html',{
'listing':listing,
'count': listing.bids.all().count()
})
What could be the problem with my code?
Also, let me provide the code for some of my models and a form as the error might be embedded in those:
Listing Model:
class Listing(models.Model):
NAME_CHOICES = [
('Fashion', 'Fashion'),
('Toys','Toys'),
('Electronics','Electronics'),
('Home', 'Home'),
('Other', 'Other')
]
title = models.CharField(max_length= 64)
date_made = models.DateTimeField(auto_now_add=True)
description = models.TextField()
user = models.ForeignKey(User, to_field='username', on_delete=models.CASCADE, related_name='user_listings', null=True)
starting_bid = models.DecimalField(decimal_places=2, max_digits=264, default=10.00)
upload_image = models.ImageField(blank=True, upload_to='media/media')
category = models.ForeignKey(Category, on_delete=models.CASCADE, to_field='name', related_name='category_listings', default=NAME_CHOICES[4][0], db_constraint=False)
listing_category = models.CharField(max_length=12, choices=NAME_CHOICES, null=True, default=NAME_CHOICES[4][0])
is_active = models.BooleanField(default=True)
watchlist = models.ForeignKey('Watchlist', on_delete=models.DO_NOTHING, related_name='listings', null=True)
Category Model:
class Category(models.Model):

('Electronics','Electronics'),
('Home', 'Home'),
('Other', 'Other')
]
name = models.CharField(max_length=12, choices= NAME_CHOICES, unique=True)
User Model:
class User(AbstractUser):
def __str__(self):
return f'{self.username} '
ListingForm`` (ModelForm```):
class ListingForm(ModelForm):
class Meta:
model = Listing
exclude = [
'date_made',
'user',
'category',
'is_active',
'watchlist'
]
Any form of help would be greatly appreciated.
When you call listing_form.save(commit=False) it returns an unsaved model instance with the submitted values. If you assign that to a variable, you can use it to set the other field values and save:
def create_listing(request):
if request.method == 'POST':
import datetime
listing_form = ListingForm(request.POST, request.FILES)
if listing_form.is_valid():
bid = listing_form.cleaned_data['starting_bid']
listing = listing_form.save(commit=False)
listing.user = request.user
listing.date_made = datetime.datetime.today()
listing.is_active = True
listing.category = Category.objects.get(name=listing_form.cleaned_data['listing_category'])
listing.save()
Bid.objects.create(user=request.user, value=bid, listing=listing)
# You should probably use HttpResponseRedirect to an `all_listings` page, rather than displaying them here
all_listings = Listing.objects.all()
return render(request, 'auctions/index.html', {
'all_listings': all_listings })
Here's a link to the ModelForm.save() docs.
Please Help!
I am trying to update a group of formsets that are related the main form (Project Information) by the main forms pk. The create form works fine, but I am finding it extremely difficult to implement the update version.
It's the save as an update part that I can't figure out for the formsets. The main form updates the database correctly. The formsets just create new records instead of updating the existing ones. I do not know how to instance the formsets.
Here the code.
view.py
#login_required
def edit_project(request):
SampleInformationFormSet = formset_factory(SampleInformationForm, extra=1)
DissolutionMethodsFormSet = formset_factory(DissolutionMethodsForm, extra=1)
form = ProjectInformationForm(request.POST or None)
si_formset = SampleInformationFormSet(request.POST or None, prefix='si')
d_formset = DissolutionMethodsFormSet(request.POST or None, prefix='d')
if request.method == 'POST':
form = ProjectInformationForm(request.POST or None)
si_formset = SampleInformationFormSet(request.POST or None, prefix='si')
d_formset = DissolutionMethodsFormSet(request.POST or None, prefix='d')
pi_pk = ''
p = ''
if form.is_valid():
pi_pk = form.cleaned_data['hd']
p = ProjectInformation.objects.get(pk=pi_pk)
form = ProjectInformationForm(request.POST, instance=p)
form.save() # This form saves correctly
for si_form in si_formset:
si_form.save() # I do not know how to attach an instance to these formsets
for d_form in d_formset:
d_form.save()
messages.success(request, 'Your project has been updated!')
return redirect('edit_project')
else:
pass
form = ProjectInformationForm(request.POST or None)
si_formset = SampleInformationFormSet(request.POST or None, prefix='si')
messages.warning(request, 'There was an error saving your form.')
study_id_select = list(
ProjectInformation.objects.values('dissolution_study_id', 'id').filter())
context = {'form': form, 'si_formset': si_formset, 'd_formset': d_formset, 'study_id_select': study_id_select}
return render(request, 'main/edit_project.html', context)
models.py I'm just going to include part of three of the seven models to keep this a little shorter.
class ProjectInformation(models.Model):

Please help if you can. This project has been a trial by fire and the flames are hot!
Finally solved it myself.

I have a problem where I want to change the thumbnail on my website of a Model (talking about 3D printing here but also Django ones) but Django does not change it.
models.py
class Model3D(models.Model):
id = models.AutoField(primary_key=True)
name = models.CharField(max_length=300)
description = models.TextField(max_length=800, blank=True)
thumbnail = models.ImageField(upload_to='models/thumbnails', null=True)
I tried two different forms.py
Version 1
class ImageUploadForm(forms.Form):
"""Image upload form."""
image = forms.ImageField()
Version 2 (ignore the following name, it was just a fast test)
class ModelCreateForm(forms.ModelForm):
class Meta:
model = Model3D
fields = ['name', 'thumbnail']
help_texts = {
'thumbnail': ("Gebe hier den Namen des Modelles ein.")
}
views.py
def save_settings(request, pk):
model = get_object_or_404(Model3D, pk=pk)
if request.method == 'POST':
# print("request.method == 'POST'" + str(dir(saveModel)))
model.name = request.POST.get('name', model.name)
model.description = request.POST.get('description', model.description)
form = ImageUploadForm(request.POST, request.FILES)
if form.is_valid():
model.thumbnail = form.cleaned_data['image']
model.save()
return HttpResponse('image upload success')
model.save()
return redirect('settings_model', pk=model.pk)
return redirect('settings_model', pk=model.pk)
I do have enctype="multipart/form-data in my template. Please help!
I'm making a stock portfolio app as a personal project. I have a form StockSymbolForm used for buying stocks. It has the fields: username, stock_symbol, and stock_qty.
I've set username to be the current user that's currently using the app - so they only need to fill stock_symbol and stock_qty.
After a valid form is submitted, I go to my admin page to check, but I don't see my new stock_symbol and stock_qty added to my model.
Here's my code:
views.py:
class PortfolioStockListView(ListView):
model = StockPortfolio
template_name = 'stocks.html'
def post(self, request):
current_user = StockPortfolioUser.objects.filter(username=request.user).first()
if request.method == 'POST':
symbol_form = StockSymbolForm(request.POST, initial={'username': current_user})
if symbol_form.is_valid():
symbol_form = StockSymbolForm(request.POST, instance=current_user)
model_instance = symbol_form.save(commit=True)
model_instance.timestamp = timezone.now()
model_instance.save()
return redirect('/')
else:
return render(request, 'stocks.html', {'symbol_form': symbol_form})
else:
symbol_form = StockSymbolForm()
return render(request, 'stocks.html', {'symbol_form': symbol_form})
models.py:
class StockPortfolioUser(models.Model):
username = models.OneToOneField(User, on_delete=models.CASCADE)
usercash = models.PositiveIntegerField(default=100000)
class StockPortfolio(models.Model):
username = models.ForeignKey(StockPortfolioUser, on_delete=models.CASCADE)
stock_symbol = models.CharField(max_length=5)
stock_qty = models.PositiveIntegerField(default=0)
forms.py:
class StockSymbolForm(ModelForm):
class Meta:
model = StockPortfolio
fields = ('stock_symbol' , 'stock_qty')
labels = {'stock_symbol': 'Stock Symbol', 'stock_qty': 'Quantity'}
How do I save the model instance properly? and why is it not saving at the moment?
In your views.py file change this
model_instance = symbol_form.save(commit=False)
model_instance.username = request.user.id
model_instance.timestamp = timezone.now()
model_instance.save()
In StockSymbolForm change this
fields = ('username', 'stock_symbol' , 'stock_qty')
Well, you don't ever seem to be setting the username. You set a timestamp, which doesn't exist as a field, but not the actual username field.
model_instance = symbol_form.save(commit=True)
model_instance.userame = request.user
model_instance.save()
As an aside, that field should be called user, as it points to the whole User object not just the username.
I am relatively new in django .I am developing a project using django where i have a option to upload image.For upload image , i have following model and view
models.py
class Photo(models.Model):
name = models.CharField(max_length = 100)
photo = models.ImageField(upload_to = 'photos', blank=False,null=True)
approved = models.BooleanField(default = False)
uploaded_time = models.DateTimeField()
description = models.CharField(max_length = 80 , blank = False , null = True)
approved_by = models.CharField(max_length = 100)
user = models.ForeignKey(User)
views.py
def UserImageUpload(request):
if request.method == 'POST':
form = DocumentForm(request.POST,request.FILES)
if form.is_valid():
messages.add_message(request, messages.SUCCESS, 'Your Image upload is waiting for Admin approval')
newdoc = Photo(photo = request.FILES['photo'],watermarked_image=request.FILES['photo'],user = request.user,name = request.POST['name'],description = request.POST['description'],uploaded_time=datetime.datetime.now(),Certified=request.POST['Certification'])
newdoc.save()
else:
messages.add_message(request, messages.ERROR, 'Something is Missing!')
else:
form = DocumentForm()
uploaded_image = Photo.objects.all()
return render_to_response('myprofile/user_image_upload.html',{'uploaded_image':uploaded_image,'form':form},context_instance = RequestContext(request))
now i want to create a auto generated image Id for every uploaded image. Don't mess up the image Id with the pk of images.Now the question is, how can i do this.
You can add it as an identity column to your DB table, which will auto increment for every new row. And it doesn't need to be a PK.
This post should help further.
