Web Scraping in Django: running scraper every day to update database or running a specific scraper for every user?
I have a project idea: a website where a user could enter search details (city, keywords, etc.) and then receive periodical job offer emails. I would like to hear your opinion on how the scraper part should work: Should I run a scraper every day? It would go through the pages of the website, building a database. Then filter the database specifically for the user and send an email with the result. Or should I build a specific scraper for every user? Every scraper would only take the information that is needed for a particular user from the website. As far as I understand django-dynamic-scraper package would fit, but it does not support the newest django version. What are your thoughts on this? Maybe there are simpler ways to implement this project? -
Unable to content Django form with extended user model
Trying to connect Django form and extended user model, but struggling to get the form to save. Basically, I'm able to authenticate user, but not save information to the CustomUser model or "profile" model for the user. I feel like I fundamentally don't understand how to extend the user model, so if you have some advice to that affect that would be very helpful. #views.py def registration(request): if request.method == "POST": form = CustomUserCreationForm(request.POST) if form.is_valid(): custom = form.save(commit=False) user = request.user custom = user.profile() custom.key = "".join(random.choice(string.digits) for i in range(20)) custom.save() username = form.cleaned_data['username'] password = form.cleaned_data['password2'] user = authenticate(request, username=username, password=password) messages.success(request, f'Your account has been created! Please proceed to agreements and payment.') return redirect('other_page') else: form = CustomUserCreationForm(request.POST) return render(request, 'registration.html', {'form': form}) Here is my models.py class CustomUser(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) key = models.CharField(max_length=25, null=True, blank=True) first_name = models.CharField(max_length=25) last_name = models.CharField(max_length=25) username = models.CharField(max_length=25) password1 = models.CharField(max_length=25) password2 = models.CharField(max_length=25) @receiver(post_save, sender=User) def create_custom_user(sender, omstamce, created, **kwargs): if created: CustomUser.objects.create(user=instance) @receiver(post_save, sender=User) def save_user_profile(sender, instance, **kwargs): if instance.CustomUser.save() def __str__(self): return f'{self.first_name} ({self.last_name})' In settings.py I added "AUTH_PROFILE_MODULE = 'app.CustomUser'".

DJANGO - Static files are being collected, but they don't want to work on local server
as a newbie in Django I'm struggling with the staticfiles within my project. Whenever I take some prepared bootstrap template something is not working, same when I try to add some javascript - and have no idea why. I tried to find the answer before, but in theory, everything should work - would be awesome if someone could guide me, cuz I feel completely lost now. Everything works fine until I want to use some advanced js/css animations. It looks like in the image - the main background doesn't load, the navibar is shattered as well... My settings I think look fine - Django collect all the static files, but they don't want to work on the local server. Everything is rooted in views.py/urls.py (settings.py) STATIC_URL = '/static/' STATICFILES_DIRS = [ os.path.join(BASE_DIR, "static") ] STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') `<!DOCTYPE html> {% load static %} <html lang="en"> <head> <meta charset="utf-8"> <title>BizPage Bootstrap Template</title> <meta content="width=device-width, initial-scale=1.0" name="viewport"> <meta content="" name="keywords"> <meta content="" name="description"> <!-- Bootstrap CSS File --> <link href="{% static 'lib/bootstrap/css/bootstrap.min.css' %}" rel="stylesheet"> <!-- Libraries CSS Files --> <link href="{% static 'lib/font-awesome/css/font-awesome.min.css' %}" rel="stylesheet"> <link href="{% static 'lib/animate/animate.min.css' %}" rel="stylesheet"> <link href="{% static 'lib/ionicons/css/ionicons.min.css' %}" rel="stylesheet"> <link href="{% static 'lib/owlcarousel/assets/owl.carousel.min.css' … -

ImportError: Couldnt import Django ... Did you forget to activate a virtual environment?
I know there are several questions/answers about this but I cant figure out what I should do. So I wanted to get started with Django and installed it with pip install and added Python37 and Python37-32 to my enviromental variables and it I guess it worked because I can run several python commands in my shell. But everytime I try to python manage.py runserver it gives me an Error. I also set up my virtual environment and activated it but I think theres a problem with Django. But because I installed it with pip install django I know its there and I can use commands like django-admin startapp ... So I guess Django is working. I dont rlly know what PYTHONPATH means and where to find it. Would be pretty nice if anybody could take a look at my error.

Why does my django pagination keeps returning the same items infinitely?
I am using django and ajax to create a infinite scroll on my website. I would like it to load more items from the database (that are in the next page) when the user scrolls to the bottom of the page. Everything is working perfectly except that it keeps returning the first page's items infinitely. For example if a user scrolls down to the end of a page instead of adding page 2's elements it just add the same elements from the first page to the bottom again. I am very sure this issue is from my views.py. I can't seem to figure out what's wrong. def feed(request): queryset2 = Store_detail.objects.filter(store_lat__gte=lat1, store_lat__lte=lat2)\ .filter(store_lng__gte=lng1, store_lng__lte=lng2) queryset3 = Paginator(queryset2, 4) page = request.GET.get('page',1) try: queryset = queryset3.page(1) except PageNotAnInteger: queryset = queryset3.page(page) except EmptyPage: queryset = "" context = { "location":location, "queryset":queryset, } # return HttpResponse(template.render(context,request)) return render(request, 'main/feed.html', {'queryset': queryset, 'location':location,}) So basically I would like to load the next page when a user scrolls to the end of the screen and if there are no more items in the next page or the next page does not exist then stop adding items. -
Converting to and from CamelCase within DRF
I am making a SOAP post request which returns data in CamelCase. I need to refactor the response back from SOAP request into snake_case. Then again I receive a request from a Restful API in snake case which I need to convert into CamelCase and then send a SOAP request. I have a mini serializer which I wrote to convert between the two, i.e. extended the to_representation method and then returned the respective CamelCase or snake_case, however I'm not sure if this mini serializer is a good way of doing it, should maybe be a helper function than serializer? Here is the serializer converting a list of objects containing name and attribute_given keys into CamelCase. class ToCamelCase(serializers.Serializer): name = serializers.CharField() attribute_given = serializers.CharField() def to_representation(self, value): data = [] for x in range(len(value)): data.append({ 'Name': value['name'], 'AttributeGiven': value['attribute_given'], }) return data I'm just looking for the best approaching solving this. Is solving this by extending the to_representation and returning custom key name at serializer level a good way or shall I write a helper function for it? -

Efficient replacement of source urls with django static urls
In django when we load image we use tag something like this: <img alt="background" src="{% static "img/inner-6.jpg" %}" /> and I use templates and build backend to those templates to learn django (for now) so when I start project all the images source urls and css file urls and javascript urls are given like : <img alt="background" src="img/inner-6.jpg" /> so I have to replace all of them with the above one which is time consuming and non-productive. Can someone please tell me the efficient way to do this (like notepad text replacement system or something like that). How do experience django developers deal with this kind of problems? Thanks in advance. (I have searched a lot about it before asking on stackoverflow but couldn't find anything) -
Django is complex select query possible for this?
I have the following model used to store a bidirectional relationship between two users. The records are always inserted where the smaller user id is user_a while the larger user id is user_b. Is there a way to retrieve all records belonging to a reference user and the correct value of the status based on whether the reference user id is larger or smaller than the other user id? Perhaps two separate queries, one where reference user = user_a and another where reference user = user_b, followed by a join? class Relationship(models.Model): RELATIONSHIP_CHOICES = ( (0, 'Blocked'), (1, 'Allowed'), (-2, 'Pending_A'), (2, 'Pending_B'), (-3, 'Blocked_A'), (3, 'Blocked_B'), ) user_a = models.ForeignKey(CustomUser, on_delete=models.SET_NULL, related_name='user_a',null=True) user_b = models.ForeignKey(CustomUser, on_delete=models.SET_NULL, related_name='user_b',null=True) relationship_type = models.SmallIntegerField(choices=RELATIONSHIP_CHOICES, default=0) -

Django taking image from Python program
I have previously written some python code which takes some information, and presents it into a chart. An example is in the link below. The python program creates the chart, then places the numbers in the chart in the relevent location. There is some randomness as to where they are placed in the smaller squares. My question is I would like to implement this in Django. Being new to Django, my thought process is I should be calling the Python code, which would create the image from the Django database, and then displaying it. I have worked out how to call the code, however there is little information about how to do so on the click of a button. This has made me question if calling the Python code is the correct way to do this? -

Create a function that identifiies object type and passes form depending on what type the object is

Add range and ><= operators to django form
I am building enterprise software which someone can use to input order data from a customer. Sometimes customers order something with length 1000+ or will order something within a range of 400-600 for example. How can I display these options in a dynamic form which inputs an integer into a model? Will my model have to have max_length min_length, max_width, min_width etc or is there a better way? I've considered creating non-required fields and dynamically displaying the form depending on a dropdown menu choice near every dimension with (greater than, equal to, less than). This will make me create around 6 new fields for a basic l/w/h input. For example: If someone wants a range they can click on the side dropdown near the dimension and select range, which will then show a new input box which submits data to max_DIMENSION. Or when a user chooses > then the database saves that field as greater than. I expect to be input a range with 2 values, or a >/=/< with a single value.
