How to run python script asynchronously in Django project?
I'm working on project where I scrap job offers and display it on my django app. My scrapper is an indenpendent python script based on requests and selenium. I need to run in Django background on every 5 minutes so it can scrap new data and insert it into my postgres db. Is there any recommended way of handling it ?

How to form URLs
I am not sure about the exact terminology here. If we have the following URL: https://www.thewhiskyexchange.com/c/331/non-vintage-champagne If I load https://www.thewhiskyexchange.com/c/331/ it would automatically add(redirect to) "non-vintage-champagne". My questions are: What is the exact terminology/the methods that are used here? Is it important to add c/331/ and a redirect(or something similar) instead of a simple domain.com/non-vintage-champagne (or domain.com/products/non-vintage-champagne or something simpler) What exactly is c/331/? Do we need to structure it that way with a letter and number or we can also use simple words or similar? Any advice how to structure the URLs in a website? I am using Django + Vue 3 I am not sure if I am asking the right questions, so any additional information or links would be appreciated -
Django chained dropdown from DataFrame or dictionary
I am new to Django and have to get familiar with it. Problem I have is I need to create a survey type view with chained dropdowns. Tutorial I checked would actually create models (data in db) and jquery, but I don't need to store any data used in dropdowns, only end result. I get JSON data via API, then I use pd.DataFrame to clean it up. Clean data should be used in dropdowns eg Country -> City, without storing it. -
django "view on site" button wrong redirect after changing DB config
I tested adding another DB (holding documents) next to a 'default' DB (for auth etc.) and surprisingly that stopped 'VIEW ON SITE' button (in admin site) to work. So when I am in the admin site: http://localhost:8002/admin/reviewer/document/<uuid_here>/change/ and I click on "VIEW ON SITE" button, it takes me to http://localhost:8002/admin/r/7/<uuid_here>/ and delivers Page Not Found: Page not found (404) Request Method: GET Request URL: http://localhost:8002/admin/r/7/<uuid_here>/ Raised by: django.contrib.contenttypes.views.shortcut Content type 7 object <uuid_here> doesn’t exist You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page. whereas previously (single 'default' DB for everything) it correctly redirected me to http://localhost:8002/reviewer/doc/<uuid_here> Any ideas what could the fix be?

How do I add non-field related date range to Django admin form
I have a django admin page which is for viewing purposes only and rather than displaying data from the model, it is displaying data for a table linked by a foreignkey to an intermediate table which is linked via a foreign key to my model. I want to apply a date range filter on the third table. class Brand(models.Model): data ... class Organisation (models.Model): data ... brand = models.ForeignKey(Brand, on_delete=models.CASCADE) class DailyStat (models.Model): stat_type = model.CharField(max_lenth=11, choices=STAT_TYPE_CHOICES date = models.DateField() organisation = models.ForeignKey(Organisation, on_delete=models.CASCADE) I then created a change_form.html template in 'templates/admin/brand' which displays the data from DailyStat which I want for the Brand. But I want to be able to filter this so I created a new form class BrandAdminForm(forms.ModelForm): from_date = forms.DateField(widget=admin.widgets.AdminDateWidget()) to_date = forms.DateField(widget=admin.widgets.AdminDateWidget()) class Meta: model = Brand fields = ['id','from_date','to_date'] And within the BrandAdmin definition, referenced it class BrandAdmin(admin.ModelAdmin): list_display = ['name','get_page_views','cqc_brand_id'] ordering = ['name'] search_fields = ['name'] form = BrandAdminForm These fields didn't automatically show in the detail page so I added the following within the form tags of {% block content %} of the change_form.html <table style="width:60%"> <tr> <td>From: </td> <td>{{ adminform.form.from_date }}</td> <td rowspan=2><button type="submit" value="Save and continue editing" class="btn viewsitelink">Filter</button></td> </tr> … -

Problem with reading excel file using pandas in webapp

Django: Map CreateView to an existing form template
I'm pretty new to Django and as an intern backend-developer, I'm asked to make a CreateView for a user to create a shop on the website. I need to make it so that it "maps" to a template my frontend colleague made, with all the fields and the styling already there. I only know how to make simple CreateViews that basically generates a form for you. But here I don't want it to do that, I want to use the already existing styled fields in the template, but I'm having a hard time finding how to do that. Here's my model (I haven't included all the lines for readability reasons, but I'll do if needed): class Dealer(models.Model, CloneMixin): dealer_check = models.ForeignKey("self",null=True, blank=True, on_delete=models.SET_NULL) published = models.BooleanField(null=True,blank=True, default=True) informed = models.BooleanField(null=True,blank=True, default=False) objectid = models.CharField(null=True,blank=True,max_length=100) language = models.ForeignKey(Language, null=True, blank=True,on_delete=models.SET_NULL) name = models.CharField(null=True,blank=True,max_length=100) street = models.CharField(null=True,blank=True,max_length=100) number = models.CharField(null=True,blank=True,max_length=100) city = models.CharField(editable=False,null=True,blank=True,max_length=100) phone = models.CharField(null=True,blank=True,max_length=100) email = models.CharField(null=True,blank=True,max_length=100) users = models.ManyToManyField(User,null=True,blank=True, related_name='dealers') isowner = models.BooleanField(null=True,blank=True, default=False, editable=False) created = models.DateTimeField(auto_now_add=True, blank=True, null=True) updated = models.DateTimeField(auto_now=True, blank=True, null=True) Here's my form: class ShopCreateForm(forms.ModelForm): class Meta: model = Dealer fields = ["name", "email", "phone", "street", "number", "description"] And here's my view (You can … -
How to cause child class to save when parent class is saved?
Is there a way to call the save method of a Child class when the Parent class is saved? I have a field some_other_value on the Child class that is updated whenever the Child is saved, and this is based off a value some_value on the parent class. However, when I save the Parent class, it doesn't update the Child class since the child's save method isn't called. I was thinking of some sort of post_save signal, but thinking whether this would cause some sort of recursive loop. class Parent(models.Model): some_value = models.IntegerField(default=0) class Child(models.Model): some_other_value = models.IntegerField(default=0) def save(self, *args, **kwargs): self.some_other_value = self.some_value * 2 super().save(*args, **kwargs) -
