Create spacing in data list
How do I space out the output, i considered using the each() method but I couldn't figure out how to use it. I can do this with Django for loop without ajax, but with ajax it seems the for loop tag doesn't work here's the code. current output = 1.0768411833.01.28164125.6340.91000 expected output = 1.07684 11833.0 1.28164 125.634 0.91000 <h2 id="prices"></h2> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script> <script> const doAjaxWithDelay = (delay) => { setTimeout(() => { var data = $(this).data() $.ajax({ url: "/price", type: "GET", success: function(data) { document.getElementById('prices').innerHTML = data; console.log(data) } }).done(() => { doAjaxWithDelay(5000) }) }, delay) } doAjaxWithDelay(0) </script> -
Django's invalid regular expression: invalid escape \ sequence [duplicate]
I'm trying to filter my records with __regex field lookup. It works fine until I started using unicode property group (\p{whatever}), or, letter group (\p{L}). DB i'm using - postgresql. Code that I got looks like this: f1 = Q(field__regex=r'[^\d\p{L}]anystr[^\d\p{L}]') f2 = Q(field__regex=r'[^\d\p{L}]strany[^\d\p{L}]') MyModel.objects.filter(f1 | f2) After launch of this code, I got this error: django.db.utils.DataError: invalid regular expression: invalid escape \ sequence I tried to dig deeper and found nothing that could cause problem in python code. Last point of exception is: django\db\backends\utils.py", line 86, in _execute, so, i placed pdb point there. There are 2 variables, sql and params. sql - contains raw sql code without values of django's Q objects yet (seems like it will be added by format strings, because of %s's) params - Q object's values itself. In my example it was: ('[^\\d\\p{L}]anystr[^\\d\\p{L}]', '[^\\d\\p{L}]strany[^\\d\\p{L}]') 1 line later exception like above was thrown again. But, If I paste one of generated values of Q in search of DB itself, no error seen. -

How can I reuse Django admin search feature?
I'm developing an application with Django.I'm using Django admin's search feature like this: class ProductAdmin(admin.ModelAdmin): search_fields = ('image_name', 'product_name', ) And it gives a very nice search on these columns. Now I want to use this search in my views and inside my code. I mean I want to reuse this search which Django uses for the admin page in my code. I've read the code of ModelAdmin class but I couldn't reuse it, because it uses some objects from other layers of Django. So I couldn't figure out how can I do this. -

Django models.CASCADE in ManyToManyRelation
I have a m2m relationship with users and posts. A user can like a many posts and at the same time a post can be liked by many users.

How do I filter a Django model by an attribute of a relationship field?
I am trying to query my 'Profile' model by the 'username' attribute of its OneToOneField relation 'User'. I have attempted to accomplish this by setting my queryset using: Profile.objects.get(owner.name = ...), however in doing so I get an error saying 'SyntaxError: expression cannot contain assignment, perhaps you meant "=="?'. This is confusing as if I set this these parameters to something like 'id = ...', I get no such error. What am I doing wrong here? If I wanted to query the 'Profile' table by the 'username' of its 'owner' relation, how would I best do this? I have attached my code below. models.py: class User(models.Model): username = CharField(max_length = 80) class Profile(models.Model): owner = models.OneToOneField('User', related_name = 'profile', on_delete = models.CASCADE) views.py: class UserProfile(generics.GenericAPIView, mixins.RetrieveModelMixin): def get_queryset(self): username = self.kwargs['username'] return Profile.objects.filter(owner.username=username) serializer_class = UserProfileSerializer def get(self, request, *args, **kwargs): return self.retrieve(request, *args, **kwargs) urls.py: urlpatterns = [ path('user/<str:username>/profile/', views.UserProfile.as_view()), ] Thanks -

Using local timezone in django admin template
After crying under my desk for a while over this problem I got the courage to come on SO and ask this question. I have a django model: entry_time = models.DateTimeField(auto_now_add=True) On my admin change_form.html and change_list.html I would like to display that object in local time. I've read the django docs on this, my biggest problem I think is that I'm modifying the template and am not directly calling the object. Settings.py: TIME_ZONE = 'UTC' USE_I18N = True USE_L10N = True USE_TZ = True I have tried changing the TIME_ZONE to US/Arizona which didn't work. I tried solutions i found at Setting Django admin display times to local time? such as custom templates using {% extends "admin/change_list.html" %} {% load tz %} {% block content %} {% timezone "US/Eastern" %} {{ block.super }} {% endtimezone %} {% endblock %} This did nothing, my time is still UTC on change_form. I tried installing a middleware package (awesome-django-timezones) that uses js to find local timezone and change it using middleware. This did nothing as well. I also tried going into options.py and adding activate() into the view that calls change_form.html-- no success. Am I missing something? How can I extend the … -

Is it possible to get a python program that uses tkinter to run in a web page using flask?
I have a python program that I would like to use in a web server. For that I need to convert it to web environment. I read that you can do it with flask. the challenge is that the program is a GUI made with tkinter. If I run the following program through the cmd: flask run, it runs in the local host, (http://127.0.0.1:5000/). If I copy the address and put it in a web browser, I get the error Internal Server Error in the web window, but a new window open in my computer with the checkbutton and the label. The program works; What I need is to put that window with the checkbutton and the label inside the web window, so I can eventually put it on a server. (I have hundreds of widgets for what i was forced to use the place.method and I don't want to code everything from scratch in another language).
