Couchx

CouchDB Adapter for Ecto3.

The Adapter supports 1 main Repo, but also dynamic repos where you can querie on multiple Dbs with a dynamic supervisor.

The supported functions in this version are:

Repo.get Struct, doc_id
Repo.all from doc in Struct, where: doc._id in ^doc_ids_list
Repo.insert Struct, doc
Repo.delete Struct, %{_id: doc_id}
Repo.update changeset

It adds a simple way to execute JS view queries with:

  def query(name, design, view_map, key, opts \\ []) do
    {adapter, meta} = Ecto.Repo.Registry.lookup(name)
    adapter.execute(:view, meta, design, view_map, key, opts)
  end

Not ideal, so open to suggestions here.

TODO:

• Repo.insert_all
• Repo.delete_all
• Bulk doc updates
• Better error handling
• Mango Queries
• A better view query pattern
• Auto indexing requested JS queries
• Index management
• Add tests
