pip3 install --user ".[ldap,tests]"
You will also need a MySQL driver, recommended drivers are
- `mysqlclient`
- `PyMySQL`
You will also need a MySQL driver, by default one of this is installed:
- `mysqlclient` (non Windows)
- `PyMySQL` (on Windows)
`setup.py` will try to install a matching driver.
#### Hint on MySQL driver on Windows:
If you want to use `mysqlclient` instead of `PyMySQL` (performance?) you have to follow [this guide](https://www.radishlogic.com/coding/python-3/installing-mysqldb-for-python-3-in-windows/)
#### Windows
Same as above, but if you want to use `mysqlclient` instead of `PyMySQL` (performance?) you have to follow this guide:
### Install database
The user needs to have full permissions to the database.
If not you need to create user and database manually do (or similar on Windows):
https://www.radishlogic.com/coding/python-3/installing-mysqldb-for-python-3-in-windows/
(
echo "CREATE DATABASE flaschengeist;"
echo "CREATE USER 'flaschengeist'@'localhost' IDENTIFIED BY 'flaschengeist';"
echo "GRANT ALL PRIVILEGES ON flaschengeist.* TO 'flaschengeist'@'localhost';"
echo "FLUSH PRIVILEGES;"
) | sudo mysql
### Configuration
Then you can install the database tables, this will update all tables from core + all enabled plugins.
*Hint:* The same command can be later used to upgrade the database after plugins or core are updated.
$ flaschengeist db upgrade heads
## Plugins
To only upgrade one plugin (for example the `events` plugin):
$ flaschengeist db upgrade events@head
## Configuration
Configuration is done within the a `flaschengeist.toml`file, you can copy the one located inside the module path
(where flaschegeist is installed) or create an empty one and place it inside either:
1. `~/.config/`

- Pros: Guaranteed execution interval, no impact on user experience (at least if you do not limit wsgi worker threads)
- Cons: Uses one of the webserver threads while executing
### Database installation
The user needs to have full permissions to the database.
If not you need to create user and database manually do (or similar on Windows):
(
echo "CREATE DATABASE flaschengeist;"
echo "CREATE USER 'flaschengeist'@'localhost' IDENTIFIED BY 'flaschengeist';"
echo "GRANT ALL PRIVILEGES ON flaschengeist.* TO 'flaschengeist'@'localhost';"
echo "FLUSH PRIVILEGES;"
) | sudo mysql
Then you can install the database tables and initial entries:
$ flaschengeist install
### Run
Flaschengeist provides a CLI, based on the flask CLI, respectivly called `flaschengeist`.

"""Flaschengeist Plugins
## Custom database tables
You can add tables by declaring them using the SQLAlchemy syntax,
then use Alembic to generate migrations for your tables.
This allows Flaschengeist to proper up- or downgrade the
database tables if an user updates your plugin.
migrations have to be provided in a directory called `migrations`
next to your plugin. E.G.
myplugin
- __init__.py
- other/
- ...
- migrations/
## Useful Hooks
There are some predefined hooks, which might get handy for you.
For more information, please refer to
- `flaschengeist.utils.hook.HookBefore` and
- `flaschengeist.utils.hook.HookAfter`
