Create table class

The class must inherits from Table class

Add primary key field

Primary key can be auto increment

NUT_PRIMARY_AUTO_INCREMENT(id)
NUT_DECLARE_FIELD(int, id, id, setId)

for declaring primary key use NUT_PRIMARY_KEY macro, if primary key is auto increment use NUT_PRIMARY_AUTO_INCREMENT

Macro	Description
NUT_PRIMARY_KEY(x)	The field x is primary key
NUT_AUTO_INCREMENT(x)	The field x is auto increment
NUT_PRIMARY_AUTO_INCREMENT(x)	The field x is primary key and auto increment

Declare field

NUT_DECLARE_FIELD(type, property_name, read_method_name, write_method_name)

Additional meta data

Macro	Description
NUT_NOT_NULL(x)	The field x is not allowed to store NULL value
NUT_LEN(x, len)	Max length of x is len in string types and in numeric typed field x will be store in len bytes
NUT_DEFAULT_VALUE(x, def)	Default value of x is def
NUT_UNIQUE(x)	Field x is unique (Not imlemented yet!)
NUT_DISPLAY_NAME(field, name)	Sets display name for field (used in model creation

Sample table

class Post : public Table
{
    Q_OBJECT

    NUT_PRIMARY_AUTO_INCREMENT(id)
    NUT_DECLARE_FIELD(int, id, id, setId)

    NUT_NOT_NULL(title)
    NUT_LEN(title, 50)
    NUT_DECLARE_FIELD(QString, title, title, setTitle)

    NUT_DECLARE_FIELD(QDateTime, saveDate, saveDate, setSaveDate)

    NUT_LEN(body, 200)
    NUT_DECLARE_FIELD(QString, body, body, setBody)
public:
    explicit Post(QObject *tableSet = 0);

};

Declare child table

If current table has one-to-many relation ship it must be declared. For example post table has a slave table named comment, every post has many comment:

NUT_DECLARE_CHILD_TABLE(Comment, comments)

First argument id table name and second is field name, m_comments must be initalized in constructor:

Post::Post(QObject *parent) : Table(parent),
    m_comments(new TableSet<Comment>(this)), m_id(0), m_title("")
{

}
