Static files are not served but accessible directly. Django, docker, nginx
I am trying to dockerize a django project with postgres, gunicorn and nginx. My problem is that static files are not served. However in browser console I see all static files being loaded properly (code 200). Also I can easily access any static file directly i.e. 127.0.0.1:8080/static/admin/.../base.css. Nginx doesn't show any errors in console either. What makes it even more strange for me, my redoc.yaml is loaded properly. Here is part of my settings.py with static: STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'static') Here is my main Dockerfile: FROM python:latest RUN mkdir /code COPY requirements.txt /code RUN pip install -r /code/requirements.txt COPY . /code WORKDIR /code CMD gunicorn api_yamdb.wsgi:application --bind 0.0.0.0:8000 Here is the Dockerfile for nginx: FROM nginx:latest COPY nginx/nginx.conf /etc/nginx/nginx.conf Here is the nginx.conf file: events {} http { server { location /static/ { root /etc/nginx/html/; } location / { proxy_pass http://web:8000; } } } And finally here is my docker-compose: version: '3.8' volumes: postgres_data: static: services: db: image: postgres:latest volumes: - postgres_data:/var/lib/postgresql/data/ env_file: - ./.env web: build: . restart: always command: gunicorn api_yamdb.wsgi:application --bind 0.0.0.0:8000 volumes: - static:/static ports: - "8000:8000" depends_on: - db env_file: - ./.env nginx: build: context: . dockerfile: nginx/Dockerfile ports: - "8080:80" volumes: … -
Django Rest Framework serialized image returns absolute system url, and not amazon s3 url
I'm currently using django-storages with my application for hosting static and media files. I'm also using imagekit on image uploads to create multiple versions of an image needed across the application. The problem arises when trying to serialize the images urls. DRF returns a url such as http://127.0.0.1:8000/media/CACHE/images/categories/tilbeh%C3%B8r/tilbehor/2fbf015bd21dba581f5d306ed4248b47.jpg, and when opening this, its returns a completely blank page. What i really need is for it to return the "real" storage url, e.g. https://domain.s3.amazonaws.com/static/media/CACHE/images/categories/tilbeh%C3%B8r/tilbehor/2fbf015bd21dba581f5d306ed4248b47.jpg.

Django Weasyprint: Timeout error loading css while site is hosted on PythonAnywhere
I'm struggling to use Django WeasyPrint correctly while exporting a template to PDF. This issue only occurs on the PythonAnywhere version; using the view on localhost works as intended. Using any other view with the same stylesheets on PythonAnywhere also works fine. The errors occur when loading these two resources: <link rel="stylesheet" href="{% static 'css/boostrap4.5.2.css' %}"> <link rel="stylesheet" href="{% static 'css/blog.css' %}"> (note: I originally used a cdn for the bootstrap css but was finding a 403 forbidden error when WeasyPrint tried to get it instead, gave up on that one) Here's the error log when weasyprint tries to use it: Failed to load stylesheet at http://kirkmania.pythonanywhere.com/static/css/boostrap4.5.2.css : timeout: timed out Failed to load stylesheet at http://kirkmania.pythonanywhere.com/static/css/blog.css : timeout: timed out And here's the server log: SIGPIPE: writing to a closed pipe/socket/fd (probably the client disconnected) on request /cv/export (ip 10.0.0.52) !!! uwsgi_response_writev_headers_and_body_do(): Broken pipe [core/writer.c line 306] during GET /cv/export (10.0.0.52) SIGPIPE: writing to a closed pipe/socket/fd (probably the client disconnected) on request /static/css/boostrap4.5.2.css (ip 10.0.0.52) !!! uwsgi_response_write_headers_do(): Broken pipe [core/writer.c line 248] during GET /static/css/boostrap4.5.2.css (10.0.0.52) SIGPIPE: writing to a closed pipe/socket/fd (probably the client disconnected) on request /static/css/blog.css (ip 10.0.0.52) !!! uwsgi_response_write_headers_do(): Broken pipe [core/writer.c line 248] … -

Add custom users with a specific attribute to the 'friends' list
I have implemented the logic of adding users to the 'friend list' from the whole list of users. models.py class VendorList(models.Model): users = models.ManyToManyField(User) current_user = models.ForeignKey(User, related_name='owner', on_delete=models.SET_NULL, null=True) @classmethod def add_vendor(cls, current_user, new_vendor): vendor, created = cls.objects.get_or_create( current_user=current_user ) vendor.users.add(new_vendor) @classmethod def remove_vendor(cls, current_user, new_vendor): vendor, created = cls.objects.get_or_create( current_user=current_user ) vendor.users.remove(new_vendor) views.py class VendorListView(TemplateView): template_name = 'event/vendor_list.html' def get(self, request): #form = EventItemModelForm() users = User.objects.exclude(id=request.user.id) vendor = VendorList.objects.get(current_user=request.user) vendors = vendor.users.all() args = { #'form': form, 'users': users, 'vendors': vendors } return render(request, self.template_name, args) def change_vendor_list(request, operation, pk): vendor = User.objects.get(pk=pk) if operation == 'add': VendorList.add_vendor(request.user, vendor) elif operation == 'remove': VendorList.remove_vendor(request.user, vendor) return redirect('/vendors/') It works and provides the list of all users whom I can add to the list. However, I need to filter this 'whole' list and display only users who have is_vendor attribute (similar to is_staff). Where should I filter users, in models or views? I have tried vendors = vendor.users.filter(is_vendor=True) which doesn't work. -
How to install Pip on a new Ubuntu upgrade
At the suggestion of others working on what was a functional Django project, I upgraded to a more recent version of Ubuntu (18). However, when I first try to run it it blows up at line 3 of the initial script module when asked to import django as a package. I tried pip -r requirements.txt, but the system said pip was an unknown package. I dropped down and used apt to load pip onto my machine (sudo apt-get pip), then tried using pip itself (pip update pip) which failed.: I also tried "pip install django", and got this: I would have thought an OS upgrade would not require re-installing all currently installed packages (seems like a no-brainer to do the work of installing everything that had been installed). But right now I am terribly stuck...obviously, having 'pip' let's you (at least) have a basic CLI tool. Any advice? -
modelformset_factory alter data after form submit
I have a modelformset_factory with some fields, and I combine it with other data from the PartRelation in a CreateView (like name, price, color ...). forms.py: class PartRelationForm: form = modelformset_factory(PartRelation, fields=("part", "qty", ), widgets={'part': forms.Select(), 'qty': forms.NumberInput()}) views.py: class PartsMixin(object): def post(self, request, *args, **kwargs): inquiry_form = InquiryModelForm(request.POST) parts_form = PartRelationForm().form(request.POST, prefix='part2inq') if inquiry_form.is_valid() and parts_form.is_valid(): i = inquiry_form.save() for form in parts_form: p = form.save(commit=False) p.inquiry = i p.save() return redirect ... return render ... class PartCreateView(PartsMixin, CreateView): model = Part the corresponding model (relation): class Part2InqRelation(CommonFunctionalities, models.Model): part = models.ForeignKey(PartBase, on_delete=models.CASCADE) qty = models.PositiveIntegerField("Quantity") inquiry = models.ForeignKey(Inquiry, related_name='inq_part', on_delete=models.CASCADE) As soon as I have no qty or no part in my form, the is_valid() method always fails. How can I alter or delete the data in the PartRelationForm before the validation? I tried iterating through them and setting them None or an other approach with cleaned_data without success already. -
Django heroku connect read-write primary key issue
i am using djagno-heroku-connect library,salesforce and heroku connect link below for library https://github.com/Thermondo/django-heroku-connect So the problem that i am facing is i have one model that is marked as read-write, so which field should i make as primary key, I can't make sf_id as pk, because when i create one object it won't be there, as this is provided by salesforce As suggested in docs create external_id, but this won't be present if data from salesforce is synced back to my database let's say postgres There is one id field in postgres which is used by heroku connect and its suggested in docs on not to use that and i am not willing to user salesforce API for this, is there any approach to do this?

Form error message overrides model error message

Creating a custom function in model to compare two foreign key max timestamps
In my Django project, I am attempting to create a custom model field that relies on comparing the values of two reverse foreign key timestamps. In this toy example, I operate some car dealerships. Cars are hired out to folks but need to be 'serviced' every time before they are hired out again. I am trying to add a 'currently_serviced' field into my Car model. A car is considered currently serviced if it has had an associated 'ServiceEvent' after the latest 'HireEvent'. I have been following the documentation on custom model fields but this doesn't help me navigate the trickiness of the reverse foreign keys and identifying the latest (before current time as I want to ignore future hires) timestamps. I have tried writing model manager classes and writing the logic into my views with F() comparisons, although would prefer as a DRY approach to declare the 'currently_serviced' attribute on the model itself as it would dynamically update as and when cars are hired and serviced and I would then be able to utilise this field in my views, such as by outputting the '% of serviced cars by dealership'. I am currently getting an attribute error, although I suspect … -
How to display content in grid format in django template when receiving dynamic data in terms of list from database?

I am storing this data in comma separated format when it comes to displaying this on template things are pretty easy. But, I want this data to be displayed dynamically as one row with two columns and as soon as two columns are filled and there is more data left to be displayed logic should should have the capability to create a new row and display the remaining content on the django-template.

How to Enforce Consecutive Numbering in "Through" Model Field
I'm using Python 3.7 with Django 3.1. I have two models: Text and Edition. There are a fixed number of texts, and users will be able to create editions in which they place these texts in whatever order they want. This is accomplished by means of a "through" model, EditionTextThrough, which keeps track of the position of a given text in a given edition: class EditionTextThrough(models.Model): text = models.ForeignKey(Text, on_delete=models.CASCADE) edition = models.ForeignKey(Edition, on_delete=models.CASCADE) position = models.PositiveSmallIntegerField( validators=[MinValueValidator(1), MaxValueValidator(372)]) class Meta: ordering = ['edition', 'position'] unique_together = ['edition', 'position'] This works fine. However, I want to enforce consecutive numbering for the "position" attribute, relative to the Edition it is paired with. Django's auto-generated IDs won't do this, because they are simply assigned to each row in the table, and don't start over with each Edition that is contained in it. Django's IDs can't do what I want for another reason as well: I want the "position" numbers to remain consecutive, even when some of them are deleted: position | edition_id | text_id 1 | uuid | 4 2 | uuid | 22 3 | uuid | 128 4 | uuid | 16 5 | uuid | 3 Now, if the … -

Django-Filter - Removing filter options that will return empty
