EctoTaggable

ecto_taggable allows to tag any row of an ecto model.

For example you have model:

odule MyModel do
e Ecto.Model
hema "user" do
field :name, :string
field :old,  :integer
has_many :tags, {"test_model_tags", Ecto.Taggable}, [foreign_key: :tag_id] # foreign_key: tag_id is necessarily
d

You can migrate this model and related tags model to the database with ecto_migrate:

.Migration.Auto.migrate(EctoIt.Repo, MyModel)
.Migration.Auto.migrate(EctoIt.Repo, Ecto.Taggable, [for: MyModel])

Insert data in the database and set tag on this data:

odel1 = repo.insert(%MyModel{name: "foo", old: 20})
odel2 =repo.insert(%MyModel{name: "bar", old: 25})
.Taggable.set_tag(repo, my_model2 :tag_name)

ecto_taggable provides ability to search tag with:

.Taggable.search_tag(repo, MyModel, :tag_name) % ==> %MyModel{name: "bar", ...}

and delete tag for all recrods with:

.Taggable.Api.drop_tag(EctoIt.Repo, MyModel, :tag_name)

or for the certain id:

.Taggable.Api.drop_tag(EctoIt.Repo, %MyModel{id: 1}, :tag_name)
