Exposing a module's data to Views2 using its API - php

Question

I'm forking the filefield_stats module to provide it with the ability of exposing data into the Views module via the API.
The filefield_stats schema is as follow:
function filefield_stats_schema() {
$schema['filefield_stats'] = array(
'fields' => array(
'fid' => array('type' => 'int', 'unsigned' => TRUE, 'not null' => TRUE, 'description' => 'Primary Key: the {files}.fid'),
'vid' => array('type' => 'int', 'unsigned' => TRUE, 'not null' => TRUE, 'description' => 'Primary Key: the {node}.vid'),
'uid' => array('type' => 'int', 'unsigned' => TRUE, 'not null' => TRUE, 'description' => 'The {users}.uid of the downloader'),
'timestamp' => array('type' => 'int', 'unsigned' => TRUE, 'not null' => TRUE, 'description' => 'The timestamp of the download'),
'hostname' => array('type' => 'varchar', 'length' => 128, 'not null' => TRUE, 'default' => '', 'description' => 'The hostname downloading the file (usually IP)'),
'referer' => array('type' => 'text', 'not null' => FALSE, 'description' => 'Referer for the download'),
),
'indexes' => array('fid_vid' => array('fid', 'vid')),
);
return $schema;
}
Well, so I implemented the hook_views_api() in filefield_stats.module & added a filefield_stats.views.inc file in the module's root directory, here it is:
// $Id$
/**
* #file
* Provide the ability of exposing data to Views2, for filefield_stats module.
*/
function filefield_stats_views_data() {
$data = array();
$data['filefield_stats']['table']['group'] = t('FilefieldStats');
// Referencing the {node_revisions} table.
$data['filefield_stats']['table']['join'] = array(
'node_revisions' => array(
'left_field' => 'vid',
'field' => 'vid',
),
'files' => array(
'left_field' => 'fid',
'field' => 'fid',
),
'users' => array(
'left_field' => 'uid',
'field' => 'uid',
),
);
// Introducing filefield_stats table fields to Views2.
// vid: The node's revision ID which wrapped the downloaded file
$data['filefield_stats']['vid'] = array(
'title' => t('Node revision ID'),
'help' => t('The node\'s revision ID which wrapped the downloaded file'),
'relationship' => array(
'base' => 'node_revisions',
'field' => 'vid',
'handler' => 'views_handler_relationship',
'label' => t('Node Revision Reference.'),
),
);
// uid: The ID of the user who downloaded the file.
$data['filefield_stats']['uid'] = array(
'title' => t('User ID'),
'help' => t('The ID of the user who downloaded the file.'),
'relationship' => array(
'base' => 'users',
'field' => 'uid',
'handler' => 'views_handler_relationship',
'label' => t('User Reference.'),
),
);
// fid: The ID of the downloaded file.
$data['filefield_stats']['fid'] = array(
'title' => t('File ID'),
'help' => t('The ID of the downloaded file.'),
'relationship' => array(
'base' => 'files',
'field' => 'fid',
'handler' => 'views_handler_relationship',
'label' => t('File Reference.'),
),
);
// hostname: The hostname which the file has been downloaded from.
$data['filefield_stats']['hostname'] = array(
'title' => t('The Hostname'),
'help' => t('The hostname which the file has been downloaded from.'),
'field' => array(
'handler' => 'views_handler_field',
'click sortable' => TRUE,
),
'sort' => array(
'handler' => 'views_handler_sort',
),
'filter' => array(
'handler' => 'views_handler_filter_string',
),
'argument' => array(
'handler' => 'views_handler_argument_string',
),
);
// referer: The referer address which the file download link has been triggered from.
$data['filefield_stats']['referer'] = array(
'title' => t('The Referer'),
'help' => t('The referer which the file download link has been triggered from.'),
'field' => array(
'handler' => 'views_handler_field',
'click sortable' => TRUE,
),
'sort' => array(
'handler' => 'views_handler_sort',
),
'filter' => array(
'handler' => 'views_handler_filter_string',
),
'argument' => array(
'handler' => 'views_handler_argument_string',
),
);
// timestamp: The time of the download.
$data['filefield_stats']['timestamp'] = array(
'title' => t('Download Time'),
'help' => t('The time of the download.'),
'field' => array(
'handler' => 'views_handler_field_date',
'click sortable' => TRUE,
),
'sort' => array(
'handler' => 'views_handler_sort_date',
),
'filter' => array(
'handler' => 'views_handler_filter_date',
),
);
return $data;
} // filefield_stats_views_data()
According to the Views2 documentations this should work as a minimum, I think. But it doesn't! Also there is no error of any kind, when I come through the views UI, there's nothing about filefield_stats data. Any idea?

Answer 1

I think your problem is in the function name: hook_views_data(), it should be filefield_stats_views_data().
hook_views_api() should also be filefield_stats_views_api().
You always replace hook with your module name when implementing them in your own modules.

Answer 2

Missing field definitions in the code above and also wrong hook_views_api() implementation. A working API implementation example can be found here: http://drupalcode.org/sandbox/sepehr/1073868.git/tree/refs/heads/master:/modules/sms_panel_views
