Detailed Description

Object Relation Mapper (ORM)

QDjango's Object Relation Mapper (ORM) strives to be both powerful and simple to use. Where possible it tries to follow django's ORM API, with a similar lazy queryset mechanism.

The object relation mapper builds upon Qt's Meta-Object System, so if you are familiar with Qt, you should feel right at home. Features include:

• support for a wide range of database backends thanks to QtSql
• creating and registering database models is easy using Qt's property system
• performing queries using querysets
• QDjango can create and drop database tables and indices for registered models
• thread-aware access to the database

None	No comparison, always returns true.
Equals	Returns true if the column value is equal to the given value.
NotEquals	Returns true if the column value is not equal to the given value.
GreaterThan	Returns true if the column value is greater than the given value.
LessThan	Returns true if the column value is less than the given value.
GreaterOrEquals	Returns true if the column value is greater or equal to the given value.
LessOrEquals	Returns true if the column value is less or equal to the given value.
StartsWith	Returns true if the column value starts with the given value (strings only).
EndsWith	Returns true if the column value ends with the given value (strings only).
Contains	Returns true if the column value contains the given value (strings only).
IsIn	Returns true if the column value is one of the given values.
IsNull	Returns true if the column value is null.
IEquals	Returns true if the column value is equal to the given value (case-insensitive)
INotEquals	Returns true if the column value is not equal to the given value (case-insensitive).
IStartsWith	Returns true if the column value starts with the given value (strings only, case-insensitive).
IEndsWith	Returns true if the column value ends with the given value (strings only, case-insensitive).
