I am attempting use Ecto Repo.get_by with multiple clauses, and I'm having trouble finding syntax examples. I need to query where either or 2 fields in the DB match, so an 'or' condition between the clauses. I can't figure out if this is even possible.
Repo.get_by(User, [username: username, email: username], prefix: :accounts)

Ecto.Repo behaviour. A repository maps to an underlying data store, controlled by the adapter. For example, Ecto ships with a Postgres adapter that stores data into a PostgreSQL database. When used, the repository expects the :otp_app as option. The :otp_app should point to an OTP application that has the repository configuration.

Queries are used to retrieve and manipulate data from a repository (see Ecto.Repo ). Ecto queries come in two flavors: keyword-based and macro-based.
Repo.get_by doesn't allow ORing the clauses. You'll need to write a full query using from, or a combination of where and or_where, and then pipe to Repo.one:
from(u in User, where: u.username == ^username or u.email == ^username)
|> Repo.one
User
|> where(username: ^username)
|> or_where(email: ^username)
|> Repo.one
To add the prefix to this query, you can do this.
