DESCRIPTION

This Yancy backend allows you to connect to a SQLite database to manage the data inside. This backend uses Mojo::SQLite to connect to SQLite.

See Yancy::Backend for the methods this backend has and their return values.

Backend URL

The URL for this backend takes the form sqlite:<filename.db>.

Some examples:

# A database file in the current directory
sqlite:filename.db

# In a specific location
sqlite:/tmp/filename.db

Schema Names

The schema names for this backend are the names of the tables in the database.

So, if you have the following schema:

CREATE TABLE people (
    id INTEGER PRIMARY KEY,
    name VARCHAR NOT NULL,
    email VARCHAR NOT NULL
);
CREATE TABLE business (
    id INTEGER PRIMARY KEY,
    name VARCHAR NOT NULL,
    email VARCHAR NULL
);

You could map that to the following schema:

{
    backend => 'sqlite:filename.db',
    schema => {
        People => {
            required => [ 'name', 'email' ],
            properties => {
                id => {
                    type => 'integer',
                    readOnly => 1,
                },
                name => { type => 'string' },
                email => { type => 'string' },
            },
        },
        Business => {
            required => [ 'name' ],
            properties => {
                id => {
                    type => 'integer',
                    readOnly => 1,
                },
                name => { type => 'string' },
                email => { type => 'string' },
            },
        },
    },
}
