- i18n is used everywhere but only requires shared or external packages, therefore it's a good candidate for living in shared
- this reduces invalid requires across frontend and server, and lets us use it everywhere until we come up with a better option

|
|
* @NOTE
|
|
*
|
|
* We define the defaults on the schema (db) and model level.
|
|
*
|
|
* Why?
|
|
* - when you insert a resource, Knex does only return the id of the created resource
|
|
* - see https://knexjs.org/#Builder-insert
|
|
* - that means `defaultTo` is a pure database configuration (!)
|
|
* - Bookshelf just returns the model values which you have asked Bookshelf to insert
|
|
* - it can't return the `defaultTo` value from the schema/db level
|
|
* - but the db defaults defined in the schema are saved in the database correctly
|
|
* - `models.Post.add` always does to operations:
|
|
* 1. add
|
|
* 2. fetch (this ensures we fetch the whole resource from the database)
|
|
* - that means we have to apply the defaults on the model layer to ensure a complete field set
|
|
* 1. any connected logic in our model hooks e.g. beforeSave
|
|
* 2. model events e.g. "post.published" are using the inserted resource, not the fetched resource

* - `published_at`: /:year/:slug
|

* - `author_id`: /:author/:slug, /:primary_author/:slug

|

* data than just the id
|
|
* - @TODO: we need to disallow this (!)
|
|
* - you should use `models.Post.edit(..)`

* - same for destroy - you should use `models.Post.destroy(...)`
