Using the Development Environment
|
|
=================================
|
|
|
|
Once the development environment is running, you can visit
|
|
<http://localhost:9991/> in your browser. By default, the development
|
|
server homepage just shows a list of the users that exist on the
|
|
server and you can login as any of them by just clicking on a user.
|
|
This setup saves time for the common case where you want to test
|
|
something other than the login process; to test the login process
|
|
you'll want to change `AUTHENTICATION_BACKENDS` in the not-PRODUCTION
|
|
case of `zproject/settings.py` from zproject.backends.DevAuthBackend
|
|
to use the auth method(s) you'd like to test.
|
|
|
|
While developing, it's helpful to watch the `run-dev.py` console
|
|
output, which will show any errors your Zulip development server
|
|
encounters.
|
|
|
|
To manually query the Postgres database, run `psql zulip` for an
|
|
interactive console.
|
|
|
|
When you make a change, here's a guide for what you need to do in
|
|
order to see your change take effect in Development:
|
|
|
|
* If you change CSS files, your changes will appear immediately via hot module
|
|
replacement. If you change JavaScript or Handlebars templates, the browser
|
|
window will be reloaded automatically. For Jinja2 backend templates, you'll
|
|
need to reload the browser manually to see changes take effect.
|
|
|
|
* If you change Python code used by the main Django/Tornado server
|
|
processes, these services are run on top of Django's [manage.py
|
|
runserver][django-runserver] which will automatically restart the
|
|
Zulip Django and Tornado servers whenever you save changes to Python
|
|
code. You can watch this happen in the `run-dev.py` console to make
|
|
sure the backend has reloaded.
|
|
|
|
* The Python queue workers will also automatically restart when you
|
|
save changes. However, you may need to ctrl-C and then restart
|
|
`run-dev.py` manually if a queue worker has crashed.
|
|
|
|
* If you change the database schema, you'll need to use the standard
|
|
Django migrations process to create and then run your migrations; see
|
|
the [new feature tutorial][new-feature-tutorial] for an example.
|
|
Additionally you should check out the [detailed testing
|
|
docs][testing-docs] for how to run the tests properly after doing a
|
|
migration.
|
|
|
|
(In production, everything runs under supervisord and thus will
|
|
restart if it crashes, and `upgrade-zulip` will take care of running
|
|
migrations and then cleanly restaring the server for you).
