Why aren't urls.py of individual apps generated automatically upon creating?

Is there a reason why it is like that? I always have to copy or rewrite the `urls.py` from another app. Couldn't it just be automatically generated like the project's urls? Is there any situation where you would not want it to be generated automatically?

[Help] How to embed a Django Admin table view (change_list?) for a single model in a user template?

Usual disclaimer: I'm working on my first larger-scale Django project, and have all the basics figured out.

What I would like to do is have both site admins and trusted users. Site admins get access to full-blown Django Admin interface. Trusted users get access to pages in my apps that allow for limited table updates. I would like just grab the basic admin table functionality, customize it, and drop it in a template for some page in my app.

For example, in my "Events" app, there are multiple models. Of these, there would be a event model that would have a page available to trusted users with an area(div) that listed upcoming events and allows edits to event fields for title, description, date, and time - but no deletion, nor edits to any other fields in that model.

Also, for all users - it would be nice to use the Admin filtering interface, especially the date filter functionality. So this feels like another specialization of the same thing - insert the admin table view (change_list?) into a regular page and disallow any editing, but use the filtering tools.

I am thinking there is a way to leverage the functionality already built for Admin site to do this, so that all the filtering options, etc. come along with it - rather than recreate from the ground up.

My searching has found a lot of information on how to customize and extend the Admin interface itself, but am thinking I am missing some important keyword in Django-lingo that would yield better results.

Mainly just looking for a push in the right direction here - or feel free to redirect my thoughts on this one if I'm out in left field. Thanks!

CCBV Down for good?

I use this reference a ton and wanted to know if there's any info out there about what's going on with the project. They have been serving the standard Heroku Application Error screen for a few days. Do the folks behind that project need some sort of help?

EDIT: Everything is okay, heroku free tier. Thanks to the CCBV maintainer for jumping on this one and giving me and probably many others a huge sigh of relief that the outage is temporary. CCBV is the jam!

What should a junior dev learn after the basics?

I graduated this may and have been working as a full stack dev since June. I think I'm getting a bit lost in what I need to start focusing on. I feel like I have a pretty good grasp on the basics of all the MTV aspects including the REST framework. I feel comfortable writing custom views, API endpoints, templates, models, and queries.

 

In the end, my company's website is just a glorified CRUD app so there hasn't been anything too challenging other than understanding undocumented legacy code, working with both mongo and postgres, and elasticsearch. I really like working with Django and would like to in whatever futures jobs, so I really need some sort of learning opportunity past the basics.

 

Any suggestions/tips/advice from seasoned Django devs? What is important to know going forward? Would you advise specializing solely on Django or diversifying with frontend frameworks?

What's the right way to create a background task following execution of a given view?

I have a view (upload) for a user to upload a file. When it's uploaded we go to a process view. After the process view is loaded I want to start a background task that pulls out the data and runs it through a function, then adds some new data into the model. I will use channels/ajax to keep the user updated, but I'm not sure how to fire the background task...


Should I use signals for this? How do I create a signal that only fires request_finished for a specific view?

I need help with URLs in Django 2.0.

I don't get it, at all. Previously I could've done something like this:

urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^', include('account.urls')),
]

And then when somebody would enter "raw" url, e.g. `website.com`, he would be redirected to the urls of the `account` app. But now I try to do something like that:

urlpatterns = [
path('admin/', admin.site.urls),
path('', include('choice.urls')),
]

I know that `url` got changed into `path` (why? I think the new name is misleading) and they got rid of all of the regex so I've been trying to match the URL so it would redirect the "raw" url into that app but with no luck. What did this get changed into and why?

Current third party user authentication for Django 2.0 and Django Rest Framework 3

I'm learning Django Rest Framework 3 to finally get some REST experience. Having searched DRF's third-party packages page, it seems like not many support Django 2.0 or haven't been updated in years. I did find django-rest-auth, which appears to support the latest Django and DRF, but that seems to be about it.

What are you using? I'm planning to extend the basic django user model, if that matters.

Help with Filtering Between Models

Newbie to Django and I need some help on how to return the right objects in my view.

Here's a link to my repo to see the entire project: [https://github.com/theaton/possessionAnaylsisApp](https://github.com/theaton/possessionAnaylsisApp)

Basically I'm trying to return a list in my view that only contains Players from the Home Team in Games. Meaning I only want to display Players that are on the Home Team (and I'll do the same for Away Team) in a specific Game. My models are as follows:

class Team(models.Model):
team_city = models.CharField(max_length=30)
team_nickname = models.CharField(max_length=30)

def __str__(self):
return self.team_city + ' ' + self.team_nickname

def team_roster(self):
return Player.objects.filter(player_team=self)

class Game(models.Model):
date = models.DateField()
home_team = models.ForeignKey('Team', related_name='home_team')
away_team = models.ForeignKey('Team', related_name='away_team')
home_team_score = models.IntegerField()
away_team_score = models.IntegerField()

def __str__(self):
return str(self.date) + ' - ' + str(self.away_team) + ' at ' + str(self.home_team)

def home_team_roster(self):
return Player.objects.filter(player_team=self.home_team)

class Player(models.Model):
player_name = models.CharField(max_length=80)
player_team = models.ForeignKey(Team, on_delete=models.CASCADE)
player_position = models.ForeignKey(Position, on_delete=models.CASCADE)

def __str__(self):
return self.player_name

I was trying to make a method that does the filtering but the team_roster returns all players, regardless of teams. I feel like maybe I should have the Team set as a foreign key in the Player model instead of the Player being a foreign key in Teams? Honestly I could be doing so many things wrong, any help would be greatly appreciated.
