What is a better way to start django project?
I am using Django framework. I have tried the following four methods to start my project python manage.py. Disadvantage: If the first request get stuck, all the other requests will get stuck. gunicorn. Disadvantage: it has conflicts with asynchronous servers. (websockets) uvicorn. Disadvantage: it doesn't process some requests randomly. gunicorn+uvicorn(gunicorn myproject.asgi:application -k uvicorn.workers.UvicornWorker -b 0.0.0.0:8000). Disadvantage: the same with python manage.py -

On my website I need to display the Model, Make and year of the car (Which are all stored in the DealershipListing, so i have no problem wiht this part) but I also need to print the address that is stored in the Dealerships table.

django: related_name of self related ForeignKey field not working | get opposite direction of self reference in template
Hej! :) I have a model to create single institutions (Institution) and can connect it to a parent institution, via parent_institution (self). So I have the institution A, which is parent to b, c, d (All themselves single institutions with an own detail view.) In the detail view of b I have the section 'parent institution' where I get A as a result, including a link to the detail view of A. <p><b>Parent institution: </b> {% if institution.parent_institution %} <a href="{% url 'stakeholders:institution_detail' institution.parent_institution.id %}"> {{institution.parent_institution}} </a> {% endif %} </p> Following this link I get to the detail view of A where I want a section with the child institutions. There should b, c, d be listed. I added a related name to the parent_institution class Institution(models.Model): name = models.CharField( verbose_name=_("Name of the institution"), max_length=200, ) parent_institution = models.ForeignKey( "self", verbose_name=_("Parent institution"), on_delete=models.SET_NULL, blank=True, null=True, help_text=_("if applicable"), related_name="child", ) normally I can follow the ForeignKey in the opposite direction via this related_name. <p><b>Child institution: </b> {{institution.child.name}} </p> but in this case this is not working and gives me 'None'.

Why doesn't this django form accept my input if it also generates the options itself?
It is a competition manager that matches the participants of a competition randomly, I call these pairs games. The game is a django model with an attribute called "ganador" to store the winner of the game. To choose the winner I use a modelform_factory called formaGanador and exclude all the attributes of the model except the "ganador" attribute. The attribute "ganador" has an option of "choices" so that the form only allows to choose one of the participants of that game and not participants of other games. Finally, when I select a participant from the list and press the submit button on the form, I receive the following response: Select a valid choice. Player A is not one of the available choices. model for games in model.py: class Juego(models.Model): torneo = models.ForeignKey(Torneo, on_delete=models.CASCADE, null=False) ronda = models.ForeignKey(Ronda, on_delete=models.CASCADE, null=False) jugadorA = models.ForeignKey(Jugador, on_delete=models.SET_NULL, null=True, related_name='jugadorA') jugadorB = models.ForeignKey(Jugador, on_delete=models.SET_NULL, null=True, related_name='jugadorB') puntuacionA = models.IntegerField(default=0) puntuacionB = models.IntegerField(default=0) ganador = models.ForeignKey(Jugador, on_delete=models.SET_NULL, null=True, default=None, choices=[('Jugador A', 'Jugador A'), ('Jugador B', 'Jugador B')]) creating the form in the views: GanadorForm = modelform_factory(Juego, exclude=['torneo', 'ronda', 'jugadorA', 'jugadorB', 'puntuacionA', 'puntuacionB']) passing and receiving the form "formaganador" from the template : def detalleTorneo(request, id): torneo … -

How to create dynamic queries with Django Q objects from parenthesis inside a string
I don't know if the title of the question is formed well enough. But essentially I would like to be able to do something like this from front end : (name="abc" OR name="xyz") AND (status="active" OR (status="available" AND age=30)) I want to the user to send this string. I will parse it in backend and form a query. I have looked at this answer and this but couldn't figure out how to solve the parenthesis here. I am thinking about using a stack (the way we solve infix expressions) to do this, but don't want to go that long route unless I am sure there isn't another/ready solution available. If someone can do this with that method, would be great too. -

I am trying to add an image to a PDF generated in Reportlab. I am trying to access the image from a Django field, specifying the full path of the file. When I run the below code I get: "Exception Value: getKeepWithNext". Any help as to what I am doing wrong would be greatly appreciated. def holding_pdf(self, course_slug, holding_slug): buffer = io.BytesIO() holding = HoldingDetail.objects.get(identifier=holding_slug) doc = SimpleDocTemplate(buffer, rightMargin=72, leftMargin=72, topMargin=72, bottomMargin=72, pagesize=A4, title=f"Why the {holding.name} is in the portfolio.pdf") elements = [] styles = getSampleStyleSheet() elements.append(Paragraph(str(holding.logo.path), styles['Normal'])) elements.append(Image(holding.logo.path)) print(holding.logo.path) doc.build(elements) buffer.seek(0) return FileResponse(buffer, as_attachment=False, filename=f"Why the {holding.name} is in the portfolio.pdf") -
