Installation

Installation is easy through CommandBox and ForgeBox. Simply type box install qb to get started.

Usage

To start a new query, instantiate a new Builder: wirebox.getInstance('QueryBuilder@qb').

By default, qb uses a generic Grammar. You can specify your specific grammar in ColdBox by setting the defaultGrammar in your moduleSettings.

moduleSettings = {
    qb = {
        defaultGrammar = "MySQLGrammar"
    }
};

If you are not using WireBox, just make sure to wire up the Builder object with the correct grammar:

var grammar = new qb.models.Grammars.MySQLGrammar();
var builder = new qb.models.Query.QueryBuilder( grammar );

Integrating With FW/1

Note: These instructions assume a basic knowledge of FW/1, a working FW/1 application structure with qb installed in the /subsystems directory (manually or via CommandBox), and a database configured to run with your application.

Wiring Up With DI/1

Once the application structure is setup, now we need to wire up qb to a bean factory using DI/1.

First we will add a mapping in Application.cfc.

this.mappings = {
    "/qb" = expandPath("./subsystems/qb")
};

Next we need to tell DI/1 where qb's components are and how to reference them for later use in the application. We can do so by defining the configuration settings in the variables.framework.subsystems struct in Application.cfc. The example below makes use of a load listener to declare each component instance and pass in any constructor arguments.

qb = {
  diLocations = "/qb/models",
  diConfig = {
    loadListener = function( di1 ) {
      di1.declare( "BaseGrammar" ).instanceOf( "qb.models.Query.Grammars.Grammar" ).done()
         .declare( "MySQLGrammar" ).instanceOf( "qb.models.Query.Grammars.MySQLGrammar" ).done()
         .declare( "QueryUtils" ).instanceOf( "qb.models.Query.QueryUtils" ).done()
         .declare( "QueryBuilder" ).instanceOf( "qb.models.Query.QueryBuilder" )
         .withOverrides({
            grammar = di1.getBean( "MySQLGrammar" ),
            utils = di1.getBean( "QueryUtils" ),
            returnFormat = "array"
         })
         .asTransient();
    }
  }
}

Usage In Your FW/1 Application

Now that everything is configured, you can launch your application with CommandBox by entering start in the terminal or use whatever method you're accustomed to.

To access qb from your application's code, you can call on it by using getBeanFactory().

// Create an instance of qb
builder = getBeanFactory( "qb" ).getBean( "QueryBuilder" );
// Query the database
posts = builder.from( "Posts" ).get();
posts = builder.from( "Posts" ).where( "IsDraft", "=", 0 ).get();
