Triplex v1.1.2 Triplex View Source

This is the main module of Triplex.

The main objetive of it is to make a little bit easier to manage tenants through postgres db schemas or equivalents, executing queries and commands inside and outside the tenant without much boilerplate code.

Using the tenant

This module has useful functions to manage your tenants, like create/1, rename/2 and drop/1, but if you’re trying to apply the tenant to a query, changeset or schema, stay with your application Repo, sending the prefix. Like this:

Repo.all(User, prefix: Triplex.to_prefix("my_tenant"))

It’s a good idea to call Triplex.to_prefix on your tenant name, altough is not required. Because, if you configured a tenant_prefix, this function will return the prefixed one.
