Is it someway possible to have two discriminator fields in one document? I
have a collection Logs in Mongo. Each log has a category field and an
action field. The combination of those fields forms the structure of the
Log.
Example: We have a category "element" and subcategories of "element" (the
action field) "create", "file"
// Log element.create{ //common Log attributes
category: 'element',
action: 'create',
//specific attributes for each Log type
parent_element: ...}// Log element.file{ //common Log attributes
category: 'element',
action: 'file',
//specific attributes for each Log type
file_size: ...
file_type: ...}
Is there a workaround how to get from document manager instances of correct
Classes by those two fields ? I tried to create a Base Log Class that has
the dicriminator field for the category attribute and an Element Class that
extends Base Log class and it this class I set the dicriminator field for
the action attribute. Then a Create Class that extends the Element. But
this way it doesn't work 'cause doc. manager returns ony Element instances.
/**
* @ODM\Document(collection="log")
* @ODM\InheritanceType("SINGLE_COLLECTION")
* @ODM\DiscriminatorField("category")
* @ODM\DiscriminatorMap({
* "element"="Element"
* })
*/class Log {}
/**
* @ODM\Document
* @ODM\InheritanceType("SINGLE_COLLECTION")
* @ODM\DiscriminatorField("action")
* @ODM\DiscriminatorMap({
* "create"="Create"
* })
*/class Element extends Log{}
/**
* @ODM\Document
*/class Create extends Element{}
