Django - Async views (api requests) and AJAX
I've used this code right here to speed up the api response of IEX. iex_var2 and iex_var1 and result are imported. I've also a form for the user where he searches for the ticker (input_ticker) The response works fine and is quit fast. async def api_test2(request): start_time = time.time() async with aiohttp.ClientSession() as session: input_ticker = request.POST['ticker'] for i in iex_var2: var2 = i url = f"{iex_var1}{input_ticker}{var2}" async with session.get(url) as res: url = await res.json() result.append(url) total = time.time() - start_time print(total) return HttpResponse(result) Now I've got two important questions about my code. How do I avoid, that each reload runs that code again? When I reload the HttpResponse, the view runs again and so on there is duplicated data in "result". Can I use a Cache herefor? I am still a beginner, probably mixing something up here? My question nr.2 is how to print this result into a template? Render does not work along with an async view, so I think AJAX is the solution, but I have neither experience with JS nor with AJAX. So I am not sure how I can the connect the "result" of my view with a template. I#ve also tried to use … -

How to properly display all inline fields associated with its parent model fields when paginating in Django template?
I'm a student and a Django newbie, and we have a project that we're trying to build using Django. In my journey to building the project I stumbled upon a problem and got stuck for weeks now. I want to display all the inline fields associated with its parent field on one page as I paginate. When I tried to paginate a model with 2 additional models that have foreign keys to it I got a weird result in my template. I can't seem to figure out how to fix it. I tried several methods on the Internet and have read numerous forums and discussions but to no avail, none has worked so far. Below are my files and a few Images: (models.py) from django.db import models class History(models.Model): BARANGAY = ( ('Alegria','Alegria'), ('Bagacay','Bagacay'), ('Baluntay','Baluntay'), ('Datal Anggas','Datal Anggas'), ('Domolok','Domolok'), ('Kawas','Kawas'), ('Ladol','Ladol'), ('Maribulan','Maribulan'), ('Pag-Asa','Pag-Asa'), ('Paraiso','Paraiso'), ('Poblacion','Poblacion'), ('Spring','Spring'), ('Tokawal','Tokawal') ) barangay_name = models.CharField(max_length=100,choices=BARANGAY,default='Alegria') barangay_img = models.ImageField(upload_to='history_imgs',blank=True) barangay_info = models.TextField() class GeoHazard(models.Model): history = models.ForeignKey(History,related_name='geohazards',on_delete=models.CASCADE) geohazard_img = models.ImageField(upload_to='history_imgs',blank=True) date_published = models.CharField(max_length=100, null=True) geohazard_info = models.TextField() class Assessment(models.Model): RATINGS = ( ('HIGH','HIGH'), ('HIGH (Mitigated)','HIGH (Mitigated)'), ('MODERATE','MODERATE'), ('MODERATE (Mitigated)','MODERATE (Mitigated)'), ('LOW','LOW'), ('UNKNOWN','UNKNOWN'), ) history = models.ForeignKey(History,related_name='assessment',on_delete=models.CASCADE) purok_name = models.CharField(max_length=50) purok_coordinates = models.CharField(max_length=100,default='unknown') flood_rating = models.CharField(max_length=100,choices=RATINGS,default='UNKNOWN') … -

How to pass "self" or Page.id to a custom admin Panel in the Wagtail CMS?
More generally speaking I want add a custom admin Panel to list some related content. To lookup this related content I need to pass the current instance of the model or at least its ID to this panel. How can I do that within these lists in which these admin panels are noted? Here is my specific example of an ArtistPage. In the editor I would like to add a panel to list WorkPages that are related to this ArtistPage: from wagtail.models import Page class ArtistPage(Page): # ... content_panels = [ # ... ListWorksPanel(artist=self), # This doesn’t work ] The panel itself is defined like that, mostly copied from the HelpPanel: from wagtail.admin.panels import Panel class ListWorksPanel(Panel): def __init__(self, artist="", template="admin/list_works_panel.html", **kwargs,): super().__init__(**kwargs) self.artist = artist self.template = template def clone_kwargs(self): kwargs = super().clone_kwargs() del kwargs["help_text"] kwargs.update( artist=self.artist, template=self.template, ) return kwargs class BoundPanel(Panel.BoundPanel): def __init__(self, panel, instance, request, form): super().__init__(panel, instance, request, form) self.template_name = self.panel.template self.artist = self.panel.artist This is more a general Python question, I think. I know how to pass "self" in functions. But how does that work here with this class as element of a list? I reckon that the __init__() method of the ArtistPage … -

Django Rest Framework: while using generics APIview I'm not able to set permissions
I want the admin user to access every user detail and the non-admin user to get access to its own detail only but Instead of this non-admin user is showing the full list of every user same as the admin user while implementing this.

Django differentiate between fetch requests
I have 2 different fetch request coming to the same view in Django. How do I differentiate between them? The first fetch request is loading new content and the second is used for a different purpose altogether but they both come from the same url and to the same view. I have the following code in my view: if request.headers.get('X-Requested-With') == 'XMLHttpRequest': return async_response(request, post) And what I need is something similar to: if request.headers.get('X-Requested-With') == 'XMLHttpRequest': if fetch function 1: django function 1 if fetch function 2: django function 2 Do i need to add some custom headers? -

Django calculated fields on custom queryset
This seems like a basic question but for the life of me I cannot seem to figure this out. I have a Recipe model that uses a custom RecipeQueryset as a manager. Now I've been doing a lot of reading on where to put business logic of the application some people suggest a "services" layer others say to put it in a custom queryset which is what I am trying to accomplish now. None of them really give an example of doing calculations though only CRUD functionality. At the moment I have a property of total_cost defined on the Recipe model but according to a lot of articles/discussions I should be moving this "business logic" to elsewhere to the custom queryset for example? Is there a way to do the calculation in a custom queryset method for a queryset of Recipe objects and calculate that total_cost for each Recipe and return that queryset with the extra total_cost field? How would I then add this so it can be used in my serializer? Model class RecipeQueryset(models.QuerySet): """Custom queryset for Recipe Model""" def all_for_user(self, user): return self.filter(user=user) # this is where I think I should put it? def total_cost(self, recipe): return # …
