</DATASOURCE>

Generic tag for fetching any kind of data. Generates a dataset and transfers it to the target components at runtime. If navigator(pager) attribute specified it takes also into account pager settings: limit, offset.

Note: Limb File Path Resolving Technique is applied to 'datasource_path' attribute of the <core:PARAMETER> tag

Anywhere in a WACT template

• target – runtime component that accepts a dataset. You can set several targets separated by commas. Target components have to support register_dataset() method.
• navigator - runtime paging component.

Other parameters can be set by inner <core:PARAMETER> tags. See runtime components method for more details.

Several <core:PARAMETER> tags

<DATASOURCE target='last_news'>
 <core:PARAMETER name='loader_class_name' value='news_object'>
 <core:PARAMETER name='datasource_path' value='fetch_datasource'>
 <core:PARAMETER name='fetch_method' value='fetch_accessible'>

 <core:PARAMETER name='limit' value='10'>
 <core:PARAMETER name='order' value='news_date=DESC; name=ASC'>
</DATASOURCE>

Runtime component for the <DATASOURCE> tag. Uses datasource attribute and parameters array to perform a fetching operation.

• get_dataset() – returns a fetched dataset
• get_total_count() - returns total number of records that satisfy conditions (limit parameter is omitted).
• set_parameter($name, $value) – a method for setting a parameter for the fetching operation.
• _set_limit_parameters($limit_string) – processes limit parameter.
• _set_order_parameters($order_string) - processes limit parameter. You can set several sorting rules by separating them with ‘;’ (see example).
• _get_datasource() – creates an object that used for the fetching operation. You can set datasource class name with <core:PARAMETER name='datasource_path' value='some_datasource'> tag. Datasource classes are stored in /core/datasource/ directory.
• _get_params_array() – processes parameters array that will be used in the fetching operation.
