Django query how to write: 'WHERE field LIKE' in Cassandra
What is the equivalent of this CQLSH statement in Django? SELECT * FROM table_name WHERE string LIKE pattern; How do I implement this in django? I tried result = table.objects.filter(string__contains='pattern') but it is giving the following error [Invalid query] message="Cannot use CONTAINS on non-collection column string" I have already made a custom index for the search field and raw LIKE query is working in cqlsh. But I need something for Django to filter on basis of keyword. Thanks in advance -

Convert two lists into a dictionary of X and Y Format
I have two lists containing around 300 decimal numbers. That I need to convert into a dictionary format like below in order to plot a scatter graph using the values within the two lists as X and Y coordinates with Chart.JS. This is the format that Chart.JS requires the data to be in. data: [{ x: -10, y: 0 }, { x: 0, y: 10 }, { x: 10, y: 5 }] I've been trying to do this in a number of different ways but each time I get it wrong. Does anyone know a good way to accomplish this? -
Django Extending User Model - Inherit Profile Form from Model
I am following a tutorial to do this in Django 3.1.7. The problem I'm having here is I'm being forced to repeat my Profile Model in my Profile Form definition. I want to use forms.ModelForm in my forms.py to inherit my Profile Model and auto-generate the forms. It seems redundant to have to spell everything out again in forms.py when it is already defined in my Models. But I'm not sure how to do that with this architecture. I've tried this approach: https://stackoverflow.com/a/2213802/4144483 But the problem with this is that UserForm is incomplete - 'password1' and 'password2' don't exist for model User. This is not a good solution for user registration. I seem to be bound to using UserCreationForm somehow. #models.py from django.db import models from django.contrib.auth.models import User from django.db.models.signals import post_save from django.dispatch import receiver class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) bio = models.TextField(max_length=500, blank=True) location = models.CharField(max_length=30, blank=True) birth_date = models.DateField(null=True, blank=True) @receiver(post_save, sender=User) def update_user_profile(sender, instance, created, **kwargs): if created: Profile.objects.create(user=instance) instance.profile.save() #forms.py rom django import forms from django.contrib.auth.forms import UserCreationForm from django.contrib.auth.models import User class SignUpForm(UserCreationForm): birth_date = forms.DateField(help_text='Required.

Dryest way to use a ManyToManyField to store values in model
I've created a real estate back end website with Django and I'm creating a way to track how agents are performing in various cities on Zillow in terms of reviews. While I could create a model that looks like this: class Agent(models.Model): url_los_angeles = models.URLField(default="https://zillow.com/los_angeles") rank_los_angeles = models.IntegerField(default=0) url_san_diego = models.URLField(default="https://zillow.com/san_diego") rank_san_diego = models.IntegerField(default=0) This doesn't seem like a very smart way to do this. Using a ManyToManyField field seems like the right approach, but I don't quite see how this would work. For example, how would an agent's individual ranking be store in the many to many field? Any insight would be greatly appreciated. -
Applying local timezone in Django templates
I use Django 3.1.7 and postgreSQL for the database. So here is the problem, after saving a date in my database I try to display it in a template with the timezone of the visitor and it's still displaying me the date UTC. I have these values in my settings.py: LANGUAGE_CODE = 'en-us' TIME_ZONE = 'UTC' USE_I18N = True USE_L10N = True USE_TZ = True my model: class Log(models.Model): user = models.ForeignKey(to=User, on_delete=models.PROTECT) log = models.CharField(max_length=255) type = models.CharField(max_length=50) date = models.DateTimeField(auto_now_add=True) company = models.ForeignKey(to=Company, on_delete=models.PROTECT) my context processor getting me the objects: def logs_processor(request): if request.user.has_perm('loging.can_see_logs'): try: logs = Log.objects.filter(company=request.user.company).order_by('-date')[:50] except TypeError: logs = None return {'side_logs': logs} else: return {'side_logs': []} And my template: {% load tz %} {% for log in side_logs %} {{ log.date|localtime }} {% endfor %} I tried without the |localtime but no luck. When I specify by hand the TZ like log.date|timezone:"Europe/Paris" That works well. As well I precise that I have pytz installed. Here what my dates look like in the database (it seams they are not naive and placed on UTC as planed): 2021-03-10 04:10:11.849048 +00:00 Any idea? -

how to use country name as default instead of code in django-countries package
I am using an a django package called django-countries which gives me access to some countries attributes in the world such as country name, country code, country flag and some other more. It seems the default appears to be the country code, i will like to know how to be able to use the country name instead of the default which is the country code. For example in my views, i have a code like this def analyse_market(request): qs = Product.objects.values('country').annotate( number=Count('pk') ).order_by('country') result = { q['country']: q['number'] for q in qs } print(result) context = {"result":result} return render(request, 'core/analyse-market.html', context) This return a result like this: {'AD': 3, 'AR': 5, 'BH': 1, 'FR': 1, 'JP': 1, 'NG': 1, 'NL': 1} In the documentation, they have different methods used such as country.name, country.code, country.flag, I have tried the country.name because it relates to what I need, but i get KeyError when using the country.name in my views. -

Django Push Notification
I wrote django app for my backend app (Android client), but i haven't idea for push notif or push data to specific client. There are exist tutorial with django-websocket. I read documentation and then conclude that websocket use group for push data. So, user subscribe to group then server push data to all user in group. This did't resolve my problem. I think open new socket based on (TCP) in-same machine (ex. port 5008) for listening client. After client request i will save data connection like address with UID, so i will send data with low socket to client while client already register. Does it work? And Secure? Please remind if there is an wrong theory. Thanks!! -

Django: connect social media local user but disallow login using social media credentials
Problem: My Django webapp allows users to login using email/password. Now I need to connect their one or more social accounts to the existing account but only for the purpose of accessing their social media content. They will not be able to login in to my webapp using their social credentials. They still have to use the existing email/password to login in to my webapp. Work so far: I have looked at django-allauth and python-social-auth but not sure if I can be selective about not allowing login but still connect the social accounts. Question: So is it possible to achieve this using django-allauth or python-social-auth ? Is there a simpler method ? Thanks ! -

Django Rest Framework Restricting Views
I am building a website that will host multiple apps. Some apps can only be accessed by certain groups from a LDAP backend. To achieve this on a pure Django stack, I used user_has_perm @user_passes_test() so that certain views can only be accessed by users who has permission to add items (I give the permission to add items to certain groups, they are automatically placed into a group from the LDAP) However, I am now migrating to a React + Django stack. How can I achieve a similar effect, where you can only access some apps if you are in the correct LDAP group. Note - I have a single react app frontend that that uses routers to get to different component(apps) -
How can I show the details of a post along with its comments using Django framework?
new to the django framework and a little rusty with coding. I am currently trying to build a tech blog from the ground up and have been using Django Central tutorials as a guide. Currently I am stuck on this tutorial- https://djangocentral.com/creating-comments-system-with-django/#comment-2272, particularly getting my views to show both the details of the post and the comments form. In the tutorial the author switches from a class based view to a function that uses get_object_or_404() in order to retrieve the post. I was able to switch over to this function without any error messages, yet the post detail returns blank. Returning to a class based view solves this issue, but I would like to go with the function provided in the tutorial. Here is the code: views.py def post_detail(request, slug): template_name = 'post_detail.html' post = get_object_or_404(Post, slug=slug) comments = post.comments.filter(active=True) new_comment = None # Comment posted if request.method == 'POST': comment_form = CommentForm(data=request.POST) if comment_form.is_valid(): # Create Comment object but don't save to database yet new_comment = comment_form.save(commit=False) # Assign the current post to the comment new_comment.post = post # Save the comment to the database new_comment.save() else: comment_form = CommentForm() return render(request, template_name, {'post': post, 'comments': comments, 'new_comment': new_comment, …
