Customising Environment Variables

To add, or modify environment variables that are supplied to the forum service, you can use the FORUM_ENV hook.

To add or modify a environment variable, update the corresponding entry in the FORUM_ENV dict as follows:

System Message: WARNING/2 (<string>, line 46)

Cannot analyze code. Pygments package not found.

.. code-block:: python

    from tutorforum.hooks import FORUM_ENV

    def _add_forum_env_vars(env_vars):
        env_vars.update({ "NEW_ENV_VAR": "VALUE" })
        return env_vars

If the environment variable already exists, it will be overridden, otherwise it will be added. Note that if multiple plugins override the same value, the last override will apply.

It is posible to use templates when setting the above values.

Caveats for the mongodb+srv:// syntax

While the newer mongodb+srv:// syntax for the MONGODB_HOST is supported, there are some tradeoffs:

  • Query parameters in the URL will be ignored by the forum. Please use the provided configuration options instead.
  • The username and password should form part of the URL in the format mongodb+srv://username:password@host/.


To debug the comments service, you are encouraged to mount the cs_comments_service repo from the host in the development container:

tutor dev start --mount /path/to/cs_comments_service

Once a local repository is mounted in the image, you will have to install all gems (ruby dependencies):

bundle install
