New Project in Django. Can't access admin
I am a beginner and have been practicing creating django projects with vscode. I created a new project and set up a superuser. I then ran the server. The development server was http://127.0.0.1:8000 as usual and the django page come up. I went to admin and the login page came up. I logged in as superuser and got the following error: This site can’t be reached 127.0.0.1 refused to connect. When I went back to vscode, the server was shut down. I thought it might be a problem with a firewall, but I have completely uninstalled my anti-virus and changed the settings on windows defender to allow VScode access through the firewall, but nothing works. I exited the project, deleted it and set up a new project. The same thing happened and it did not matter what browser I used. I have set up a dozen projects before and never had this problem. -
Template tag into column name
I'm trying to add filter field from django-filter to replace column name in django-tables2. Is there any way to do that?

I use django_filters.ChoiceFilter as filter type. -

How to require authentication to all views using social-auth-app-django? (All views are showing to non authenticated users)
I'm using social-auth-app-django version 3.1.0, and the login using Google OAuth2 is apparently running fine (I can succeed to login and get redirected back, also the user data from login is saved correctly (username, email)) But all my routes/views are accessible without authentication, even with the SocialAuthExceptionMiddleware (It was suposed to block this kind of unauthorized access I guess).

Efficient way of running Django query over list of dates
I am working on an investment app in Django which requires calculating portfolio balances and values over time. The database is currently set up this way: class Ledger(models.Model): asset = models.ForeignKey('Asset', ....) amount = models.FloatField(...) ... class HistoricalPrices(models.Model): asset = models.ForeignKey('Asset', ....) price = models.FloatField(...) date = models.DateTimeField(...) Users enter transactions in the Ledger, and I update prices through APIs. To calculate the balance for a day (note multiple Ledger entries for the same asset can happen on the same day): def balance_date(date): return Ledger.objects.filter(date__date__lte=date).values('asset').annotate(total_amount=Sum('amount')) Trying to then get values for every day between the date of the first Ledger entry and today becomes more challenging. Currently I am doing it this way - assuming a start_date and end_date that are datetime.date() and tr_dates a list on unique dates on which transactions did occur (to avoid calculating balances on days where nothing happened) : import pandas as pd idx = pd.date_range(start_date, end_date) main_df = pd.DataFrame(index=tr_dates) main_df['date_send'] = main_df.index main_df['balances'] = main_df['date_send'].apply(lambda x: balance_date(x)) main_df = main_df.sort_index() main_df.index = pd.DatetimeIndex(main_df.index) main_df = main_df.reindex(idx, method='ffill') This works but my issue is performance. It takes at least 150-200ms to run this, and then I need to get the prices for each date (all … -
Django Add Recaptcha V3 To Allauth Login
I was able to follow this answer to be able to implement Google Recaptcha V3 to my allauth sign up page. Now I would like to do the same thing for the allauth login page. I tried using the same method as the sign up page but did not have success. Here is what I tried doing replicating the answer above: https://dpaste.org/UXcD How does one go about doing this? If possible, I would like to keep the the default allauth functionality the same and would not like to override it. I would like to figure out how to do this on all allauth pages not just the signup and login pages. If there is one universal way to do it for all the allauth pages, that would be great. Otherwise I will ask separate stackoverflow questions on each one. -
How do I make a childless node have an input box that will post a number so it can call a python function?
As the question states, I need a childless node to act as input (pretty input preferably) so I can call a Python function and return a value. I would like it all to happen in javascript so it's seemless. Does anyone know how I can do that? It may involve doing something to the following- h = t.append("g").classed("body-group", !0); return h.append("image").classed("body-box", !0).attr("xlink:href", "{% static 'body box bg.png' %}").attr("width", 1e-6).attr("height", 1e-6) Here is the JSFiddle. Hopefully it helps you understand what I mean by childless node. -
Nginx not serving multiple uploaded images over about 200kb | Will serve when uploaded one at a time
I am new to nginx, and deployment in general. I've succesfully deployed a Python/django site that has a page with various "listings", and each listing has its own page with 20-30 images. When all the images are uploaded through the admin area for each listing, at only 200kb or so each, the images are not served and show blank on the front-facing website -- but when i upload between 1-6 at a time, they are served. So adding a few at a time and reloaded is the only way to upload all the images, and its a pain. I imagine this gives Nginx a chance to cache the few images before the next 1-6 images are uploaded -- so the solution could lie here somewhere. Below are my settings. I've sifted through other stack overflow questions and adjusted a few settings according to answers to other related questions ive found. Ive tried increasing the "client_max_body_size" to 20M, and have now set it to 0, so it will be disregarded - neither seem to fix the problem. Would greatly appreciate y'alls help in troubleshooting this. Thanks! http { client_max_body_size 0; proxy_max_temp_file_size 0; proxy_buffering off; sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout … -

Django automatically performing the collectstatic command
In my project, I have a main static folder and a sub folder named static. When I make changes in my sub folder named static (which I specified in COLLECTSTATIC_DIRS within the settings file), I save the file and run the collectstatic command. This successfully saves the changes, however is really inefficient as I am constantly changing css and Javascript files inside my project, which I store as static files. I browsed the web, and came across a solution named whitenoise, which is a pip package. But this package only works for a short period of time, and after a few times of closing and opening my project folder, it completely stopped working. Does anybody have another solution to deal with this problem? Thank you. -

Django rest framework ordering - set the location of None values
Using Django Rest Framework 'ordering_fields' for allowing sorting by all the model fields. I've added a new field that allows sorting by, but the requirement is that when sorting ASC - the None values will be first, and when sorting DESC - they will be last. The default behavior seems to be the opposite. Is there a quick way to tell the view where I want to put the None values results? Django version is 2.1.5. Django rest Framework version is 3.7.7 This is part of the model - class Item(models.Model): PRIORITIES = ( ('1', 'Low'), ('2', 'Normal'), ('3', 'High'), ) identifier = models.IntegerField(default=-1) title = models.CharField(max_length=1000) priority = models.CharField(max_length=50, choices=PRIORITIES, null=True, blank=True) Part of the view: class ItemViewSet(viewsets.ModelViewSet): ordering_fields = tuple(serializer_class.Meta.fields) -

Default image in Django model ImageField does't work
I have a huge problem with default image in my django model, in model.ImageField. My users/models.py: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) title = models.CharField(max_length=120) image = models.ImageField(default='default.jpg', upload_to='profile_pics') And my project/urls.py: if settings.DEBUG: urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) In my project/settings.py I have: MEDIA_ROOT = os.path.join(BASE_DIR, 'media') MEDIA_URL = '/media/' On website, src of my image is (unknown)... Every image I upload in my admin panel is ok. Just this default, when user has no image. What is wrong with this? I done it once in the past and everthing worked. Could you help me? -
python ../manage.py collectstatic - RuntimeError: Max post-process passes exceeded
I have a Django app with a React frontend deployed on Heroku. When I try to make changes then run python ../manage.py collectstatic it seems to be post-processing an infinite amount of files. It just goes on forever until it finally times out. When I run the same command in my development mode everything works fine. I can't figure out what's wrong. Is the files being brought over incorrectly? Here is the full message: Post-processing 'All' failed!
