Tag model

<model> define a database model

name: model
xml namespace: http://moyaproject.com/db

Defines a database model, which maps data stored in a database table on to Moya objects.

Models are referenced by their libname in database expressions, the name attribute is used when creating tables. If you convert a model instance to a string, it will return the value of the repr attribute, with substitutions made with the object context.

Example

<model name="Permission" libname="Permission" xmlns="http://moyaproject.com/db"
    repr="Permission '${name}' ${description}">
    <string name="name" required="yes" null="no" blank="no" length="30" unique="yes"/>
    <text name="description" null="no" default=""/>
</model>
