heroku-django | Heroku plugin alias for running Django management | Platform As A Service library

I'm trying to install django-filer. But when I run manage.py migrate I get AttributeError: 'Manager' object has no attribute '_inherited'. I don't know what that means. (I started this project with Heroku starter template https://github.com/heroku/heroku-django-template)

I initially thought that perhaps I forgot to install JPEG and ZLIB, but to my understanding they are default since Pillow 3.0.

I have a Django application that is running on Heroku. I am using Postgres with Django and when I first committed the files and ran heroku run python manage.py migrate, the initial migrations worked fine. I then created a new app restaurant in which I created a new model.

I ran the local makemigrations and migrate and it created a new file restaurant/migrations/0001_initial.py.

The problem is that when I now run heroku run python manage.py migrate it says there are no migrations to apply. I tried

heroku run python manage.py migrate restaurant

but there's an error CommandError: App 'restaurant' does not have migrations.

I have logged into the console and the migration files are there so I was wondering if I should be doing something like:

I have this program that I have managed to upload to heroku without error. But when I open it in the browser, then if I keep in there a line that uses Regexp, I get "internal server error". If I comment it out it's fine.

I have looked at similarly titled questions about Heroku giving "internal server error", but they don't involve Regexp, and they haven't given me any ideas as to what I need to do to make it work. For example Heroku deployment internal server error the person was using python and a package he had installed was incompatible, that doesn't seem relevant to my issue. This one Heroku + Django Internal server Error a guy had to import something called djcelery. Well, maybe I have to import something somewhere, but I don't know what, but it wouldn't be djcelery 'cos i'm not using django.

I'm trying to configure my django app on Heroku for the first time. I've made it to the point of pushing my code to "heroku master", but I'm getting a ModuleNotFound error:

ModuleNotFoundError: No module named 'UsefulFunctions'

Here's the full trace:

--UPDATE SOLVED--

The problem wasn't my code, it was the HTTP server library I was using. Gunicorn apparently didn't work the way I needed it to out of the box, so this post below helped point me to Waitress as an alternative HTTP server library. Now my progress updates the way it's supposed to.

=============================================

How things are working on my development runserver:

I have a Django app that updates a progress html tag using Ajax requests (currently I am using POST but I have used GET successfully as well on my development runserver). Everything works great. The Ajax request calls a function in my view.py that returns a JsonResponse with the updated data from my business logic happening in views. I am using setInterval with setTimeout to control the number of calls and clearInterval when I reach certain values.

Production deployment to Heroku:

I am currently trying to deploy to Heroku and have been 99% successful. My template renders correctly, so I can see my page and submit the form for processing. The 1% problem here is that my Ajax requests are not getting updated data and I don't know why. It's like my Ajax requests are just getting the initialized variable values of zero and continue to return those values.

I am console.logging the JSON returned from the Ajax call:

I am new to publishing django apps on heroku. I have read their tutorials and figured I would start simple by modifying their template django project.

So far everything was good.

Then I made an app as one does, made a model and ran

I have my Django application deployed on Heroku in a free dyno Currently, I am sending some GET and POST requests from JQuery-1.12.4 version

In my local development version of my application, the requests to my REST endpoints services it’s works Here an example of the fetch of posts of an user, consuming from ajax to endpoint rest service

This is my localhost Django server

I deploy on Heroku free dyno this same user interface, but the behavior is the following:

The server throw an error 500, although was happen some inusual or strange Previously, when I create an user for first time in my Heroku deployment to this user, the create and fetch post functionality it’s works O.K. like in my local environment development.

Heroku accept GET and POST request from JQuery AJAX ONLY to this user, such as follow in this picture:

I Unknown the reason which Heroku like production/testing server deployment does not accept or accept limited AJAX requests. Is possible (I think so, and will be too logic) that this behavior to be due to I am using free dyno heroku server?

Why only accept ajax request to just an user and other users like the images show above, does not works the ajax requests?

In this question talk about the topic, but I don’t have clear this subject

What other option suggest to me in relation to deployment of my project?

AWS EC2? may be?

The Heroku free dyno, don't let me look the logs due to in this free dyno, does not saved files ..

I appreciate some orientation about it.

Best Regards

UPDATE

I can look the logs in my heroku deployment, according to this answer

By the moment, the logs in the GET and POST operation only tell me about of status 500

This is the logs when I perform the GET request

I am having trouble with deployment of twitter bootstrap on my heroku client. My html code is not showing like it should (alignment, special table layouts, etc)

All is working locally, but i assume it has to do with the static files that don't get transferred correctly.

This is the static file structure, but have a look how it looks like when i open the "source chrome console" on my live heroku verson.

View of how the folder structure should be

Folder structure of deployed code on heroku

It looks like some folders are "stitched" one to another. what could be my issue? should i avoid "-" and "_" in my file names?

thanks for the help.

based on extra questions, I added more info on my settings.py file. I followed a tutorial to get all the stuff right. Also whitenoise was installed, added to wsgi.py.

I have an Django app deployed on Heroku, but due to some requirement I had to create a basic nodejs file and I wish to run it on the same dyno. I googled for solutions but couldnt come up with much apart from the blogs, which all are same https://blog.heroku.com/heroku-django-node So, I did install buildpack mentioned, and my profiles are: Procfile:
