Hosting Flask App on Heroku

Hi there,

I've been working through deploying an application on Heroku.

On my local host I run my application with:
*python manage.py runserver*

As I understand it this runs a Development server and should not be used in production.

I am assuming i need to refactor my application to run on Heroku with the standard
*web: gunicorn app:app*

Any suggestions on how to refactor my code/file tree? Thanks!

FileTree:

* myApp(root)
* -templates
* -admin.py
* -__init__.py
* -auth.py
* -config.py
* -manage.py
* -models.py
* -Procfile
* -requirements.txt
* -.gitignore

Examples of people reporting fee contribution from Django trademark usage?

From https://www.djangoproject.com/trademarks/

>You may incorporate the Django name into any website or product whose purpose is to organize, educate or inform the Django community, provided that:
>
> <snip>
>
> If a fee is to be charged for the product, or for access to any or all of the material on the website, a clear statement must exist declaring what proportion of those fees will be retained by the authors, and what proportion, if any, will be contributed back to the DSF. A link to this statement must be prominently displayed on the website or product.

Anyone got good examples of people doing this? I had a cursory browse of https://www.twoscoopspress.com/ and https://www.oreilly.com/ but couldn't find anything - I'd love to see example wording and example percentages!

How bad have I screwed up?

So I made a web application that is going to be used by multiple users, but at a low frequency (let's say around 10-20 applications a day). I haven't tested what happens if I submit multiple applications concurrently...

What is the best way to test this? I'm using SQLAlchemy if that means anything.

Nitpicking: Naming convention for forms and view functions

I want to be consistent with the naming convention of my forms and view functions so that I can better memorize their exact names without needing to look them up. The question is the order of nouns and verbs.

Example: You have a view where you can add and remove members from a party invite list, and also assign someone else to be the party host if you are the current host. The view will be called `party_members`.

You will need 3 form classes. What should they be called?

* Option A - VerbNoun: `AddMemberForm`, `RemoveMemberForm`, `ChangeHostForm`
* Option B - NounVerb: `MemberAddForm`, `MemberRemoveForm`, `HostChangeForm`. (Actually, should it be called `MemberAdditionForm` and `MemberRemovalForm`? This case makes option A easier...)

And the view should call subfunctions. What should they be called?

* Option A: `add_member`, `remove_member`, `change_host`
* Option B: `member_add`, `member_remove`, `host_change`

And if you choose option A for the form, must you also choose A for the view, and vice versa? Sorry for the nitpicking, I couldn't find this in pep8. It really bothers me when I mix my conventions because then I'm always guessing what the functions/forms are called.

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?
