Django talk: Re: Heroku and DJango

Hi Charlotte,

I spotted the problem.

You need to add 'django-filters' to your settings.py file.

Like so:

INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'maintenance',

'django-filters',
]

Then run python manage.py migrate (if the app needs a database schema, the command will generate it.

Try this?

Kind regards,

Lloyd

I have a Procfile and a Pipfile. The Procfile was put there using touch . Procfile in Git Bash.

When I try to push to Heroku, now I get this error for django_heroku, but you can see, it's plainly installed and imported at the top of my settings file.

Should I complete uninstall and re-install Python?

make sure that you use the right package in your requirements.txt

This is the package that everyone uses:

django-filter
https://pypi.org/project/django-filter/

This is another package with a very similar name

https://pypi.org/project/django-filters/

I have that. That's not the problem. My specific problem is django_filters. My app worked totally fine until I added these filters. My questions was: has anyone had trouble with django-filters and if so, how did you fix it?

Heroku use a "buildpack" https://devcenter.heroku.com/articles/buildpacks to do automate some things in the deployment.
you can attach one or more buildpacks to your project in heroku
you can also create your own buildpack to customize it.

specifically for Python, the heroku python buildpack (https://github.com/heroku/heroku-buildpack-python) will:

- search a "requirements.txt" file on root directory and install all packages listed on that file.
- search pipenv related files and install all packages listed on that file.

in short, have a requirements.txt file in your root directory

ok, stupid question....

is there a heroku pip install?

all of my dependencies are installed and listed on my requirements.txt file just like they're supposed to be.

do i pip install somewhere OTHER than my folder in my virtual environment?

i could be totally crazy, but i don't remember every using heroku pip install.....

It sounds like the package django-filters is not installed on your Heroku environment.

Do you have a dependency file suck as a Pipfile or requirements.txt? If you do, you will need to install all dependencies listed there on your Heroku server (at least those you need for production use).

The only error I keep seeing is "No Module Found" for django-filters

But, I don't understand why it runs perfectly on my local host, every single page, then heroku just hates django filters. I was hoping someone else had the same issues and remembered. But, I will follow up with the error logs in a sec. Thanks ya'll!!

Hi Charlotte,

What sort of error do you see?

Also, have your checked your logs on Heroku?

Lastly, if you have a sandbox on Heroku, you could run the site there in debug mode to get more specific error information.

Kind regards,
Lloyd

I need help.

I've followed the directions to a "T."

1. My site works PERFECTLY on my local host in my virtual environment. NO errors, migrates fine, runs fine and looks beautiful.

2. BEFORE I added Django-filters to my pages, it worked GREAT on Heroku.

3. AS SOON as I put the DJango_filters in it, BOOM, Heroku won't run it. I can find literally no documentation except for the textbook info from DJango, which doesn't troubleshoot at all.

Has anyone had this trouble already?

I have to get this up and running!

ANY suggestions would be helpful. ANY.....
