Model Binding

Model Binding

SwiftFFDB implementation of model binding based on the Codable protocol of Swift 4
create class or struct and implementation FFObject protocol:

class Person: FFObject {

    var primaryID: Int64?
    var name : String?
    var sex : Bool?
    var memoryColumn : String?
    var age : Float?
    required init() {
        
    }
    
    static func memoryPropertys() -> [String]? {
        return nil
    }
    
    static func customColumnsType() -> [String : String]? {
        return nil
    }
    
    static func customColumns() -> [String : String]? {
        return nil
    }
}

Column mapping type

SQLite type	Swift type
text	String
float	Float,Float32,Float64
double	Double,Date
integer	Int,Int8,Int16,Int32,Int64
Bool	Bool
text	Default
Blob	Data

Custom Column

static func memoryPropertys() -> [String]? can help you overlook column,If you don't want to save memoryColumn in SQLite:

    static func memoryPropertys() -> [String]? {
        return ["memoryColumn"]
    }

SwiftFFDB column have default mapping type,but is also can cnovert to other type,use static func customColumnsType() -> [String : String]?:

    static func customColumnsType() -> [String : String]? {
        return ["age":"integer"]
    }

object can use func update(),func update(),because primaryID alway is PRIMARY KEY AUTOINCREMENT,if you don't want primaryID AUTOINCREMENT,you can implementation static func customColumnsType() -> [String : String]?:

    static func customColumnsType() -> [String : String]? {
        return ["primaryID":"integer"]
    }

If you do this,you should be use FFDBManager

static func customColumns() -> [String : String]?can map column name:

    static func customColumns() -> [String : String]? {
        return ["name":"nick_name"]
    }
