Flippant v0.4.0 Flippant.Adapter.Postgres View Source
This adapter provides Postgres 9.5+ backed rule storage.
The adapter relies on a table with the following structure:
name
- Atext
orvarchar
column with a unique constraint. The adapter makes heavy use ofUPSERT
functionality, which relies on unique names.rules
- Ajsonb
column where rules will be stored. The use of jsonb and jsonb specific operators means the Postgres version must be 9.5 or greater.
In the likely chance that you’re using managing a database using Ecto you
can create a migration to add the flippant_features
table with the
following statement (or an equivalent):
CREATE TABLE IF NOT EXISTS flippant_features (
name varchar(140) NOT NULL CHECK (name <> ''),
rules jsonb NOT NULL DEFAULT '{}'::jsonb,
CONSTRAINT unique_name UNIQUE(name)
)
If you prefer you can also use the adapters setup/0
function to create
the table automatically.
