Quickstart

If you want to have a quick look or just run the project locally, you can get started by either forking this repository or just cloning it directly:

git clone [email protected]:vitorfs/colossus.git

Ideally, create a virtualenv and install the projects dependencies:

pip install -r requirements/development.txt

Create a local database:

python manage.py migrate

Start development server:

python manage.py runserver

Open your browser and access the setup page to create an admin account:

http://127.0.0.1:8000/setup/

PS: Campaign scheduling will not work out-of-the-box. You need to install a message broker and setup Celery properly.

Tech Specs

• Python 3.6
• Django 2.1
• PostgreSQL 10
• Celery 4.2
• RabbitMQ 3.7
• Bootstrap 4
• jQuery 3.3

PostgreSQL and RabbitMQ are soft dependencies. Other databases (supported by Django) can easily be used as well as other message broker compatible with Celery.

The jQuery library is more of a Bootstrap dependency. There is very little JavaScript code in the project. For the most part the code base is just plain Django and HTML templates.

Complete list of Python dependencies can be found in the requirements files.

Documentation

This is just a pre-release of the project and I still have to work on a proper documentation and user guides.

For now you will only find documentation of the internal APIs in the source code.

Who's using Colossus?

Right now just myself. I'm currently using it for my blog newsletter at simpleisbetterthancomplex.com.

colossus's Issues

Documentation

Please make some documentation. How does it compare with Mautic? It would be great to have similar tool written in Python! :)

Need help with celery/rabbitmq configuration

I recently setup colossus. And the main web app works great! Thanks for building this.

I installed and ran rabbitmq as instructed but for some reason I am not able to get celery to talk to rabbitmq to schedule and send emails. Any documentation or links on how I could setup this up?

Thanks a lot!

• Basic simple text email template
• Basic sign up pages

Perhaps consider renaming the EmailTemplate model.

Email Not Sending

Hi there. I followed your instruction from the blog on connecting the domain to mailgun and ensured everything is set up properly. I can send emails manually with swaks.

However, I edited the "Emails" portion in settings.py and it seems nothing I do can make it work. The following is a screenshot of my code. Can you please give some insight?

Is Colossus under active development?

I am evaluating mail list managers for a large client. Is Colossus being actively developed and supported? If we have installation difficulties, can we get help?

Thanks!

SMTP configuration

Hi vitor I luv u r blog, I'm new to Django.I tried to configure the SMTP credentials with my gmail account but it shows the following error

And also I got a mail from gmail saying Sign In attempt was blocked
So I think gmail won't allow me to use their service for bulk mailing or
Any suggestions .. Thank you in advance

Feature request: use of django channels instead of celery?

Is it possible to use colossus with channels, and this way use Django Foundation supported core features, only?

Subscribe page

Installing it on a server

Are there an instructions to install the program not locally but to host it on a domain. I checked the documentation and it only gives the instructions to install it locally and not publicly. Does anybody know how to do it?

Remove checklist method and use full clean method

Feature request: enable the use of django-rest-framework endpoints/routes for subscribers

Use of a API endpoint instead of a template for the newsletter subscription

Internal Server Error on Heroku

The deployment to Heroku worked fine, but when I tried to submit the SMTP credentials I got a 500 Internal Server Error. The log says this:

ValueError: Missing staticfiles manifest entry for 'vendor/bootstrap-4.1.3/css/bootstrap.min.css'

This is very strange, because it happens only after I try to update the values, but the template used for both GET and POST requests is the same.

Update:
I get the error only when setting the port to 465, if I use 25 or 587 there are no issues. This points me into the direction of the form verification used to validate data (this). I'l need to debug it further to understand what is happening and why the error is with the staticfiles manifest
