Django inlineformset issue
Helo, i want to ask you, how to add dynamic forms with formsets, i have this code , it works correctly but it dont send data to database, can you tell me how to work with this, what do .empty_form part in this formset enter code here <form id="post_form" method="post" action="{% url 'home' %}" enctype="multipart/form-data"> {% csrf_token %} {{ form.as_p }} <a href="javascript:void(0)" id="add_form">Add Form</a> <br><input type="submit" name="submit" value="Submit" /> {{ form_images.management_form }} </form> <script src="{% static 'multiimages/js/main.js' %}"></script> <script> var form_count = {{form_images.total_form_count}}; $('#add_form').click(function() { form_count++; var form = '{{form_images.empty_form.as_p|escapejs}}'.replace(/__prefix__/g, form_count - 1); $('#post_form').prepend(form) $('#id_form-TOTAL_FORMS').val(form_count); }); </script> views class ItemCreateView(LoginRequiredMixin, SuccessMessageMixin, CreateView): template_name = "multiimages/index.html" success_message = 'Item successfully added!' form_class = ItemForm success_url = "posts" model = Item def get_context_data(self, **kwargs): context = super(ItemCreateView, self).get_context_data(**kwargs) context['form_images'] = ItemImageFormSet() if self.request.POST: context['form_images'] = ItemImageFormSet(self.request.POST, self.request.FILES) else: context['form_images'] = ItemImageFormSet() return context def form_valid(self, form): context = self.get_context_data() form_img = context['form_images'] with transaction.atomic(): form.instance.user = self.request.user self.object = form.save() if form_img.is_valid(): form_img.instance = self.object form_img.save() return super(ItemCreateView, self).form_valid(form) -

psycopg2-binary installation into a virtual environment fails when trying to compile source code
I am trying to install psycopg2-binary into my Django project. I am using a virtual environment and the command I'm running is pip install psycopg2-binary However, I'm getting a massive error message, the gist of it is this: Error: pg_config executable not found. pg_config is required to build psycopg2 from source. Please add the directory containing pg_config to the $PATH or specify the full executable path with the option: python setup.py build_ext --pg-config /path/to/pg_config build ... or with the pg_config option in 'setup.cfg'. If you prefer to avoid building psycopg2 from source, please install the PyPI 'psycopg2-binary' package instead. But, hey, I'm installing exactly 'psycopg2-binary' Why am I getting all this mess? -
How can I display images from my Django DB?
Currently, although it may not be best practice, I have images stored in my django database and want to fetch them to display in a gallery page. However, I cannot get the image to display at all, which I think is because it does not arrive at the correct path. <img src ="{% static 'img/' object.image %}"> This code is to try and arrive at the correct directory for the uploaded image which is \AFA\src\artForAll\static\img Also object.image comes from this model class GalleryPost(models.Model): title = models.CharField(max_length=120) description = models.TextField(blank =True, null=True) artist = models.CharField(max_length=120) featured = models.BooleanField(default= False) image = models.ImageField(null = True, blank = True, upload_to = "static/img/") All of the other fields here work and I can see that the image is being uploaded to the correct place. -
Need Assistance with Raw MySQL Query in Django or Calling a View in Django that Does Not Error from No Primary Key Inclusion
I am working on a project that deals with capacity and resource planning for a small business. I have built an app using a Django that facilitates collection of data for assigned tasks and target goals and then compares that to user entries made against tasks assigned to them. The query for the Finance department should display as two tables on a single page. After researching this topic for some time, I have found two ways that sound best for dealing with the specific SQL queries needed: Use the Raw SQL option for Django to create the lists. Create a View in MySQL and set the model in the model file as a managed=False model. There are several problems impeding progress with this query that seem to stem from the need query sets have in Django to have a primary key value. SQL Queries The following are the two queries as they are executed successfully in the MySQL Workbench: SELECT projects.project_number AS 'project', projects.start_date AS 'start_date', projects.target_date AS 'target_date', SUM(tasks.target_hours) AS 'target_hours', SUM(activities.hours) AS 'billed_hours', (SUM(tasks.target_hours) - SUM(activities.hours)) AS 'remaining_hours' FROM activities INNER JOIN tasks ON activities.task_id = tasks.id INNER JOIN projects ON tasks.project_id = projects.id GROUP BY projects.project_number, tasks.task_number, … -
Django page that uploads csv in memory and sends off json to api
I am attempting to use django to make a site that interacts with an api for the user. The first page of the site needs to be a csv upload, that then parses the data into a json format and sends if off to the api. I've gone through the django tutorial for the polls app, and have a minimal understanding of django. But it is really overwhelming. I was able to get the csv upload from this site working: csv upload But that stores the data to a model. (Which may ultimately be ok.) But I was thinking that I could just upload the csv and convert it straight to a json without storing it? I think I'm just looking for some direction on how to have a simple upload where the upload buttom is just a submit that triggers the csv ingestion, formatting, and api request. The only thing I think I need to store is the response from the request. (It returns an ID that I need in order to retrieve the results through a different API call.) I also notices that the current view only updates the table with new rows. So I was able to … -

Django foreign keys queryset displayed in react-redux
I know that this question was asked a lot of times, but I can't find the answer to my specific problem. I have tried to get to the solution both on the backend (Django) and on the frontend (React.js and Redux) but I can't find it. I'm trying to make a simple dependent dropdown for car brands and car models, but I can only get the full list of models and not only the ones that are related to their brand. I'm new at Django and I don't know if my mistake is that I'm retrieving all data in my serializer or if I'm making the foreign key relationship wrong.

How can I iterate through each item in a database and display them in divs on my html page with django?
I have some code written to find the first post in the database and output it to my page, but I', not sure how to go about iterating through the database. I've done similar things before but this is my first time using django and bootstrap. My view currently looks like this: def gallery_view (request): obj = GalleryPost.objects.get (id =1) context = { 'object' : obj } return render(request, "gallery.html", context) This works well enough for 1 object but as you can see it takes a set ID of 1, so I need to somehow iterate this to fetch every item from my DB and somehow output them properly. -
pytest-django: Register a database type after creation of test databases
I have a django model field that registers a database type: class FieldMeta(type): def __init__(cls, name, bases, clsdict): super().__init__(name, bases, clsdict) cls.register_type() def register_type(cls): db_type = cls().db_type(connection) cursor = connection.cursor() try: cursor.execute( "CREATE TYPE foo AS (first integer, second integer);" ) _logger.warn("creating type") except ProgrammingError: pass cls.python_type = register_composite( db_type, connection.cursor().cursor, globally=True ).type _logger.warn("registering composite") def adapt_composite(composite): return AsIs(...get sql...) register_adapter(Foo, adapt_composite) class FooField(models.Field, metaclass=FieldMeta): def db_type(self, connection): return "foo" This works fine in these situations: Database already knows about type foo Database does not know about type foo The problem is that pytest-django seems to run these init methods before creating the test database, meaning that the test database does not have the required type. I can fix this on individual tests by calling FooField.register_type() in the setUpClass method of the test, but this is not ideal, since it should always be present. I tried overriding the django_db_setup fixture to look like this: @pytest.fixture(scope="session") def django_db_setup( request, django_test_environment: None, django_db_blocker, django_db_use_migrations: bool, django_db_keepdb: bool, django_db_createdb: bool, django_db_modify_db_settings: None, ) -> None: """Top level fixture to ensure test databases are available""" from django.test.utils import setup_databases, teardown_databases setup_databases_args = {} if django_db_keepdb and not django_db_createdb: setup_databases_args["keepdb"] = True with django_db_blocker.unblock(): db_cfg … -

Should I be adding the Django migration files in the .dockerignore /.gitignore file?
This is probably a duplicate of this question. My question is how should I approach this when working in a docker environment so for my project I have a docker-compose.yml and docker-compose-deploy.yml for my production environment and obviously migration files are generated only in the docker images and aren't included in my version control system. How should I approach this? should I stop using Docker as my development environment and go for something like virtual environments or even machines? -
Multiple authors for blogpost
I am a bit stuck on trying to solve this So I have a webapp, and decided to add a blog section using wagtail. This means I have quite a few pages and models already preexisting, that I do not want to touch, as well as some users already. I am aware of the owner field in the base Page class, but can't see a way to extend to into a m2m field. To achieve this, I have created a custom user model at users.User. For blog community purposes, I wanted to add the option of picing an avatar and setting a biography, so I added those two (avatar and bio are newly added fields) class User(AbstractUser): name = models.CharField(_("Name of User as displayed to other users"), blank=True, max_length=255) company = models.ForeignKey(Company, null=True, on_delete=models.CASCADE) job_title = models.CharField(max_length=100) avatar = models.ForeignKey('wagtailimages.Image', null=True, blank=True, on_delete=models.SET_NULL, related_name='+') bio = models.TextField(max_length=300, blank=True) Then I have a classic Blogpost page, with title, body streamfield etc... However, I am trying to replace something where you can add multiple post editors, and each of them has edit rights. So I tried something like this: First an orderable since I need many2many: class PostAuthorsOrderable(Orderable): page = ParentalKey("blog.BlogPost", related_name="post_authors") … -

From:{self.start} to {self.finish}" def get_sum_participators(self): return self.participators.count() class EventInviteRequest(models.Model): from_event = models.ForeignKey(Event, on_delete=models.CASCADE, related_name='from_event', null=True) to_profile = models.ForeignKey(Profile, on_delete=models.CASCADE, related_name='to_profile', null=True) timestamp = models.DateTimeField(auto_now_add=True) def __str__(self): return f"From {self.from_event} to {self.to_profile}" This is a function i'm trying to use, but it sends request to 'event' creator. def from_event_to_user_invite_request(request, id): event = Event.objects.get(id=id) to_profile = Profile.objects.get(id=id) event_invite, created = EventInviteRequest.objects.get_or_create( request, from_event=event, to_profile=to_profile) return redirect('events:event_page', event.id) Could you give me some tips how to fix the problem Thank you -

Can anybody help me to find out why the db values are not showing up in the admin form?
I am a newbie so please help me in resolving this issue. I have a DurationField in my models.py. I have overridden the widget attribute of the field in admin.py.

Headless Django-Oscar - Correct middleware/session setup
I am a bit confused about the correct setup for a headless middleware/session setup using django-oscar-api. The documentation for the latter is telling me to use oscarapi.middleware.ApiBasketMiddleWare if I want/need to mix "normal" django-oscar and django-oscar-api. The same documentation tells me to use oscarapi.middleware.HeaderSessionMiddleware if django-oscar is being communicated from an "external client using Session-Id headers". In my case I am not using Session-Id headers, but only communicate with oscar via api calls. What would be the correct setup/path for my case? Can I just use the oscarapi.middleware.ApiBasketMiddleWare and just use api calls? How will it handle anonymous baskets and merging of baskets after user login(jwt)?
