Evaluate a readonly field upon creating a new object in Djano admin
Assuming a the following model # models.py class Person(models.Model): name = models.CharField(max_length=40) birthdate = models.DateField() age = models.CharField(max_length=3) # dont mind the type, this is just an example :) The desired behavior would be to have the age field hidden while the user creates a new Person object, and evaluate its value when the user submits the form. To achieve this, I created a ModelAdmin with a custom ModelForm as follows # admin.py from django.contrib import admin from django import forms from .models import Person from dateutil.relativedelta import relativedelta import datetime class PersonForm(forms.ModelForm): def clean(self): cleaned_data = super(PersonForm, self).clean() birthdate = cleaned_data.get('birthdate') cleaned_data['age'] = relativedelta(datetime.date.today(), birthdate).years return cleaned_data class PersonAdmin(admin.ModelAdmin): form = PersonForm exclude = ('age',) admin.site.register(Person, PersonAdmin) However, after submitting the form, the age field does not get populated, possibly because it is excluded. If I remove the exclude then it works, but the form displays the age field which is not the desired behavior. -

django cache error - site displays old version sometimes
I seem to have a weirdly unique issue I can not find anything about on the web. I have django 2.0 running on an AWS EC2 instance. Recently I deployed some new code that works fine on localhost. At first, everything seemed to work fine on the deployment server. But the server seems to randomly load an old version of the site. At one moment, the new code (including template tags, new HTML and JS updates) is loaded and displayed just fine, on the next page refresh, the page behaves as if the template tags and HTML were not uploaded. Oddly enough, the JS seems to always be the new version, as it throws errors in the console. Now, I have checked Nginx, disabled the cache, cleared the django cache, removed the whole project files from the server and reuploaded everything, but the error seems to persist. Of course I also have restarted the server multiple times. Also, I have tested it on multiple browsers on multiple systems, all resulting in the same behavior. Does anybody have any idea what could be the issue here? -
Best way to code multiple decisions in Python
I have the following practical problem (related to Django/Python). I'm trying to get the following in the most efficient piece of Python code -> There are 2 items to be checked: Is the user logged in? if not show a login page, else check if the request is a post request. Is the request a post request?

Celery chord not releasing redis pubsub channel after apply_async
I am starting a chord from celery inside my django app in response to a request. The chord executes correctly, but the pub-sub channel is never released by django. Killing the django server releases the channel and it then disappears from redis-cli pubsub channels. Celery 4.1.1 or 4.2.0rc4 Redis 4.0.9 Python 2.7.15 Running locally, 1 celery worker, 1 api server Results do not matter in this case (but docs say to not ignore them) After hitting /api/start/ and watching the tasks complete in the tab running celery, I see 2 channels remaining. Killing django removes the channels, killing the celery worker has no effect on them. redis-cli pubsub channels 1) "celery-task-meta-chunk-1" 2) "celery-task-meta-chunk-2" I see the channels persist when everything goes right, so no errors are thrown.

Checking if a string is a prefix of any URL pattern
Inadvisable or not, my Django site assigns each user a page at the root, e.g., /rgov. I use a character set whitelist, so creating index.html or something nefarious should be prevented. My URL configuration also routes user pages last, so it should not be possible to hijack /admin or anything else by registering the corresponding name. However, I'd like to prevent users from registering admin, since their page will be broken. Here is my attempt: def is_reserved(username): r = urls.resolvers.get_resolver('mysite.systemurls') hit = False for path in ('/{}', '/{}/'): try: r.resolve(path.format(username)) hit = True break except urls.exceptions.Resolver404: continue return hit Here, the mysite.systemurls module defines every URL pattern except for the user pages. This does prevent picking the username admin because there is a route defined for /admin/. But it does not prevent api, because while there is /api/foo/bar, there is no route for /api/. Is there a way to test if there is a route that is a suffix of /api/ (for example)? Since URL patterns are regular expressions, maybe it's not so easy, but in a theoretical sense it should be possible. -
HTML table not rendering properly

How to auto fill SlugField instead of overriding save()?
Hello Awesome People I wonder if there is a way to generate slug, rather than overriding the save() methods of my models. Here's how I used to do: def save(self, *args, **kwargs): if self.pk is None: self.slug = create_slug(self) super(ModelName, self).save(*args, **kwargs) create_slug is a function that generates the slug with slugify def create_slug(instance,new_slug=None,field="name"): ''' long stuff to ensure the slug is unique ''' return slug As django can do in Django Admin by automatically filling the slug field. Possible that we can simply add an additional argument models.SlugField(field='name'). by adding this argument, django will make sure to take the value of field = name before saving to generate the slug without always overriding the save() method by copy/paste a lot of code to generate a slug for each model that We have. I'm a little tired of copying this for all models, any hint will help! Thank you in advance!
