DESCRIPTION

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

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

Backend URL

The URL for this backend takes the form mysql://<user>:<pass>@<host>:<port>/<db>.

Some examples:

            

              
              
# Just a DB
mysql:///mydb
# User+DB (server on localhost:3306)
mysql://user@/mydb
# User+Pass Host and DB
mysql://user:pass@example.com/mydb
            
          

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 AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(255) NOT NULL,
    email VARCHAR(255) NOT NULL
);
CREATE TABLE business (
    id INTEGER AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(255) NOT NULL,
    email VARCHAR(255) NULL
);
            
          

You could map that to the following schema:

            

              
              
{
    backend => 'mysql://user@/mydb',
    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' },
            },
        },
    },
}
