The following environment variables configure the addresses of the databases, some credentials, some application behaviours and the localization preferences.
When using docker-compose, you should provide the name of the service in your [docker-compose.yml](../docker/docker-compose.yml) file (`postgres` by default).
When using docker-compose, you should provide the name of the service in your [docker-compose.yml](../docker/docker-compose.yml) file (`redis` by default).
When using docker-compose, you should provide the name of the service in your [docker-compose.yml](../docker/docker-compose.yml) file (`elasticsearch` by default).
Your members will receive email notifications containing links to your of Fab-manager.
You must properly configure these variables to match URL of this instance, to prevent broken links.
Typically, `DEFAULT_PROTOCOL` will be `https` (`http` if you are in development, or if you set `ALLOW_INSECURE_HTTP`).
The variable `DEFAULT_HOST` should be your domain name (eg. fabmanager.example.com), and is also used for visits statistics (configuration of Google Analytics).
By default, these variables are not present in the env file, because they are only used once, when running the database seed with the command `rails db:seed`.
Configure Ruby on Rails localization settings (currency, dates, number formats ...).
Please, be aware that **the configured locale will imply the CURRENCY symbol used to generate invoices**.
_Eg.: configuring **es-ES** will set the currency symbol to **€** but **es-MX** will set **$** as currency symbol, so setting the `RAILS_LOCALE` to simple **es** (without country indication) will probably not do what you expect._
If your locale is not present in that list or any locale doesn't have your exact expectations, please open a pull request to share your modifications with the community and obtain a rebuilt docker image.
You can find templates of these files at https://github.com/svenfuchs/rails-i18n/tree/rails-4-x/rails/locale.
See [github.com/summernote/summernote/lang/summernote-*.js](https://github.com/summernote/summernote/tree/v0.7.3/lang) for a list of available locales.
Please, be aware that **the configured locale will imply the CURRENCY displayed to front-end users.**
_Eg.: configuring **fr-fr** will set the currency symbol to **€** but **fr-ca** will set **$** as currency symbol, so setting the `ANGULAR_LOCALE` to simple **fr** (without country indication) will probably not do what you expect._
See [github.com/fullcalendar/fullcalendar/lang/*.js](https://github.com/fullcalendar/fullcalendar/tree/v2.3.1/lang) for a list of available locales. Default is **en-us**.
In Rails: set Time.zone default to the specified zone and make Active Record auto-convert to this zone. Run `rails time:zones:all` for a list of available time zone names.
**BEWARE**: years format with less than 4 digits will result in problems because the system won't be able to distinct dates with the same less significant digits, eg. 50 could mean 1950 or 2050.
If set to `true`, and the application in started into a staging environment, this will enable the Crowdin In-context translation layer for the front-end application.
See [Crowdin documentation](https://support.crowdin.com/in-context-localization/) for more details about this.
In the previous versions of Fab-manager, much more settings were configurable from environment variables.
Starting with Fab-manager v4.5.0, these settings can be configured from the graphical interface, when logged as an administrator.
Nevertheless, it is possible to keep the configuration in the `env` file, using a combination of `LOCKED_SETTINGS`, `rails fablab:setup:env_to_db` and the [mapping table of `env_to_db`](../lib/tasks/fablab/setup.rake#L105).
