*
|
||
|
|
* The Postdata array is a simple intermediate data format
|
||
|
|
* for the Post content and metadata.
|
||
|
|
* It is slightly abstracted from the SQL format itself but will
|
||
|
|
* only reformat keys, *not* do any alteration of the data itself.
|
||
|
|
*
|
||
|
|
* Any supported fields will be integrated into the database.
|
||
|
|
* Other fields will be saved in a JSON structure, and will
|
||
|
|
* be restored afterward.
|
||
|
|
*
|
||
|
|
* The following fields are mandatory for *writing*
|
||
|
|
* - path: String, must be sanitized to consist of just alphanumeric
|
||
|
|
* characters, `_-./`
|
||
|
|
* used to identify the post itself
|
||
|
|
*
|
||
|
|
* The following fields may be returned by the database:
|
||
|
|
* - id
|
||
|
|
* - created_at
|
||
|
|
* - updated_at
|
||
|
|
* - view_count
|
||
|
|
*
|
||
|
|
* The following fields may be supported by the database:
|
||
|
|
* - markdown: String, markdown of the post. May be
|
||
|
|
* stored separately and won't be returned by default!
|
||
|
|
* - type: String, defining the type of the post
|
||
|
|
* - title: String, self-explanatory
|
||
|
|
* - tags: Array of strings
|
||
|
|
* - settings: Hash, recursively merged settings (calculated by DB!)
|
||
|
|
*
|
||
|
|
* The following fields are *recommended*, but nothing more:
|
||
|
|
* - icon: String, optionally defining
