For example, this is perfectly valid: class Tag(Entity): name = Field(Unicode) entries = ManyToMany('Entry') # this line is optional! articles = ManyToMany('Article') # this line is optional! class Entry(Entity): title = Field(Unicode) tags = ManyToMany('Tag') class Article(Entity): title = Field(Unicode) tags = ManyToMany('Tag') > I guess I'm looking for your recommendations regarding "best > practices" for implementing a tagging system on top of Elixir, when > one of the requirements is that the tags can be applied to different > classes (that do no share a common ancestor). As is said in the recipe, it depends on what you need: in the basic use case, standard ManyToMany relationships are your best bet. -- Gaëtan de Menten http://openhex.org --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "SQLElixir" group.
