How to make Django's ImageField app specific?
I've read through a few answers/articles at these links, but am still confused as all of them SEEM to be slightly different than what I'm after: here here here here here I am looking to make use of Django's ImageField function for uploading images from my admin page, to my portfolio/blog's app space. My folder structure looks like this: Portfolio_Blog_Website |---personal_portfolio_project |---projects_app |---migrations |---static |---img |---templates So I want to upload images to/display on the template from, the app > static > img folder. Currently, I have STATIC_URL = 'static/' set, and I'm manually drag and dropping image files into that folder, and using models.FilePathField(path="/img") in the model, and displaying them (in a for loop) with <img src="{% static project.image %}">, which works. I want to switch to be able to upload images from the admin page, and then display them on the app's page like they're supposed to. From what I've read, we have to define a MEDIA_ROOT and MEDIA_URL variable to use with models.ImageField(upload_to="img/"). The problem I see is that MEDIA_ROOT needs to be an ABSOLUTE path to the folder, which I COULD set as \\C:\Portfolio_Blog_Website\projects_app\static\img, however this isn't necessarily what I want because I'm specifically targeting the … -
Grouping ModelMultipleChoiceField in custom group and permissions form in django
I'm to implement a custom form for assigning permissions for groups in django. I have several apps in the project and every one defines its own set of permissions within its own 'AppPermissions' model. I'm currently using a ModelMultipleChoiceField with a CheckboxSelectMultiple widget. Like so: app_permissions = Permission.objects.filter(content_type__model='apppermissions') permissions = GroupedModelMultipleChoiceField( app_permissions, widget=forms.CheckboxSelectMultiple ) Now this already displays the checkboxes I need for displaying the permissions but a requirement is that they must be grouped by app. In a header/content fashion: App1_Name_Header [] App1_name_Permission1 [] App1_name_Permission2 [] App1_name_Permission3 App2_Name_Header [] App2_name_Permission1 [] App2_name_Permission2 etc... Is there a way to implement this? I'm very inexperienced with django so if there's a way of building a widget or a custom field that can accomplish this, any guidance will be appreciated. -

django-s3direct 2.0.2 admin upload not displaying in Django 3.2
I am in the process of upgrading my versions after a period of neglect. Previously I was on Django==2.2.24 and django-s3direct==1.1.5. Downgrading django-s3direct to 1.1.5 but keeping Django 3.2 restored the functionality of django-s3direct, so the issue seems to lie within the newer version of django-s3direct itself. In the admin the S3 direct upload form is not showing up -- it should appear in the space to the right of "Local image:" in the screenshot below: However, all the markup for the element is in the source of the page. I discovered that the CSS from /static/s3direct/dist/index.css appears to be hiding it (what you see below is the CSS straight from the file; it was not modified by any JS that ran on the page). s3direct worked prior to this upgrade. I'm not attempting anything custom in the code. models.py: class Image(models.Model): local_image = S3DirectField(dest='misc', null=True, blank=True) admin.py: admin.site.register(Image) I also don't have anything custom running on my admin pages. All the other JS/CSS files pulled into this page are files included with the Django admin. I ensured that all I followed all set-up steps for the latest version (I added my access credentials directly to settings.py). I don't see … -
Adding a multiple file field to a Django ModelForm
I'm wanting to create a form that allows multiple image uploads. I've got a Listing model that looks like this: class Listing(models.Model): location = models.CharField("Address/Neighborhood", max_length=250) class ListingImage(models.Model): listing = models.ForeignKey( Listing, related_name="images", on_delete=models.SET_NULL, null=True, ) image = models.ImageField() I'm using django-crispy-forms to create the form on the page but I cannot figure out how to get the listing field onto the page. class ListingModelForm(forms.ModelForm): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.helper = FormHelper() self.helper.layout = Layout( Fieldset( "Location", Div("location", css_class="col-md-12 col-lg-6") ) ) class Meta: model = Listing fields = "__all__" -
Why is the >= operator in python working like a > in a if statement?
I have an if statement that checks whether whatever is submitted in a Django form is greater than or equal to the listing_price (initial price of the item) and greater than all other bids before saving. The second part of the conditional is working, but the form will only save if the submitted value is greater than the listing_price, not equal. The greater than or equal to operator is working like a greater than operator instead. What could be causing the problem and how do you fix it? views.py def listing(request, id): #gets listing listing = get_object_or_404(Listings.objects, pk=id) listing_price = listing.bid bid_form = BidsForm() #code for the bid form bid_obj = Bids.objects.filter(listing=listing) other_bids = bid_obj.all() max_bid =0 for bid in other_bids: if bid.bid > max_bid: max_bid = bid.bid if request.method == "POST": bid_form = BidsForm(request.POST) #checks if bid form is valid if bid_form.is_valid(): new_bid = float(bid_form.cleaned_data.get("bid")) if (new_bid >= listing_price) and (new_bid > max_bid): bid = bid_form.save(commit=False) bid.listing = listing bid.user = request.user bid.save() else: return render(request, "auctions/listing.html",{ "auction_listing": listing, "form": comment_form, "comments": comment_obj, "bidForm": bid_form, "bids": bid_obj, "message": "Your bid needs to be equal or greater than the listing price and greater than any other bids." }) else: return … -

Adding button to a field in a form to add data from another form Django
So, I have this html file with a model form and I would like to add a button '+' to just one field of the form to to open a modal with another smaller form to fill out and just take information from one column. I already have the way to open the modal and the second form, in the database I am guessing I will need a foreign key, but I am still trying to figure out how to implement the button right next to the field. So far, I have this in my forms.py file: class contractsform(forms.ModelForm): class Meta: model = Contratos fields = '__all__' widgets = { 'name': forms.TextInput(attrs ={'class': 'form-control'}), 'contractee': forms.TextInput(attrs={'class': 'form-control'}), 'contractor': forms.TextInput(attrs={'class': 'form-control'}), 'start': forms.NumberInput(attrs={'class': 'form-control', 'type': 'date'}), 'end': forms.NumberInput(attrs={'class': 'form-control', 'type': 'date'}), 'cost': forms.NumberInput(attrs={'class': 'form-control'}), 'type': forms.Select(attrs={'class': 'form-select'}), 'department': forms.Select(attrs={'class': 'form-select'}), 'description': forms.Textarea(attrs={'class': 'form-control', 'rows': 3}), 'product': forms.TextInput(attrs={'class': 'form-control'}), 'attached_file': forms.FileInput(attrs={'class': 'form-control'}), 'notification': forms.CheckboxInput(attrs={'class': 'form-check-input'}), } I added attrs just to make the fields pretty. I would like to add it to the contractor field, with bootstrap 5, but I am new to Django and the manual confused me a little bit. -
Django CSRF verification failed even with @csrf_exempt
I've got a web service written in Django that has a py file with a bunch of view functions that are decorated with @csrf_exempt. It's all working as it has been for years. I recently added another function and entry in urls.py. I used the same pattern as all the other view functions -- decorated with @csrf_exempt, but for this one function the server responds with a CSRF verification failed. a snippet of my urls.py url(r'changepassword$', websvc2_account.changepassword), url(r'resetpassword$', websvc2_account.resetpassword), url(r'getcodetodeleteaccount$', websvc2_account.getcodetodeleteaccount), url(r'deleteaccountwithcode$', websvc2_account.deleteaccountwithcode), url(r'setuserdetails$', websvc2_account.setuserdetails), The function I added: @csrf_exempt def getcodetodeleteaccount(request): ... These views are called from mobile apps, so I do not want CSRF and all of them are decorated with @csrf_exempt. This new function is the only one that doesn't work. Any help or clues would be appreciated. Thanks -

Cloud Foundry Django app `cf push` logs the error `port 5432 failed: Connection refused`
I am deploying a basic Django app with Cloud Foundry. The app appears to be unable to connect to or authenticate with the database. I encounter the error after I run the cf push -f manifest.yml command. It returns Start unsuccessful and suggests I look at the logs with the cf logs app-name-1 --recent command.

Django: Switch a form in template depending on choice field
I am looking for a way to switch and display a form in template, depending on choice in CharField in another form. My app has the following models: class Damage(models.Model): damage_place = models.CharField() damage_date = models.DateField() class DamageType1(models.Model): damage = models.ForeignKey(Damage) ... class DamageType2(models.Model): damage = models.ForeignKey(Damage) ... class DamageType3(models.Model): damage = models.ForeignKey(Damage) ... Damage model has a DamageForm(forms.ModelForm) that is filled in by another user. Each DamageType model has different fields (marked as ... for simplicity) and own DamageTypeForm1(forms.ModelForm), DamageTypeForm2(forms.ModelForm) and DamageTypeForm3(forms.ModelForm). There is also a form in a template specifying which DamageType to choose: class DamageSpecify(forms.Form): DAMAGE_CHOICES = [ ('DamageType1', 'DamageType1'), ('DamageType2', 'DamageType2'), ('DamageType3', 'DamageType3'), ] damage_type = models.CharField(choices=RODO_CHOICES) And now, after choose specific damage_type in DamageSpecify I would like to display the filled DamageForm and empty DamageType(1, 2 or 3) in template to fill and save both forms. How could this be done? -
Django Allauth redirect to localhost instead of 127.0.0.1
I have a custom User class, which is shown on the main page: After a successful log in, django redirects me to the localhost page shown above. I also have an API that connects the backend to the frontend. However, it communicates with http://127.0.0.1/, which has a different user. In my views I only have: urlpatterns = [ path('', views.index, name='index'), path('api/tableEntries', views.ReactView.as_view(), name="api"), path('api/getUser', views.getUser.as_view(), name="getUser"), path('accounts/', include('allauth.urls')), ] And in my settings, I have the redirect variable set like this: LOGIN_REDIRECT_URL = 'index' I have 2 questions: I read in other threads that localhost and 127.0.0.1 sometimes resolve to different domains, and share different cookies. But why do they resolve to different domains? How do i fix it so that the redirect goes to 127.0.0.1 and I can access it with an API call? -

column "value" is of type smallint but expression is of type timestamp with time zone LINE 1: ... '2022-06-16T23:17:27.223553+00:00'
_Hi! I want to add time like "00:00". class Time(models.Model): day = models.DateTimeField(null=True) value = models.DateTimeField(auto_now_add=True, null=True) def add_time(request, str): if request.method == 'POST': form = TimeForm(request.POST) time = request.POST.get('time') time = Time(id_goal=goal, day=datetime.now(), value=time, description=description) time.save() When i had value = models.TimeField(null=True) it was good and worked before I had deployed to Heroku. After it wrote me: django.db.utils.ProgrammingError: column "value" is of type smallint but expression is of type timestamp with time zone which I didn't understand and now I have a big headache for over two-three days. Haha :P -
