Drupal 7 hook_schema not installing database table - drupal-7

Question

Any help would be brilliant.
function request_gold_pack_schema() {
$schema['request_gold_pack_customer_details'] = array(
'description' => 'Table to store all customer details.',
'fields' => array(
'rid' => array(
'type' => 'int',
'not null' => TRUE,
'default' => 0,
'auto increment' => TRUE
),
'title' => array(
'type' => 'varchar',
'length' => 10,
'not null' => TRUE,
'default' => ''
),
'first_name' => array(
'type' => 'varchar',
'length' => 50,
'not null' => TRUE,
'default' => ''
),
'last_name' => array(
'type' => 'varchar',
'length' => 50,
'not null' => TRUE,
'default' => ''
),
'house_name_no' => array(
'type' => 'varchar',
'length' => 50,
'not null' => TRUE,
'default' => ''
),
'street' => array(
'type' => 'varchar',
'length' => 160,
'not null' => TRUE,
'default' => ''
),
'town' => array(
'type' => 'varchar',
'length' => 50,
'not null' => TRUE,
'default' => ''
),
'county' => array(
'type' => 'varchar',
'length' => 50,
'not null' => TRUE,
'default' => ''
),
'telephone' => array(
'type' => 'int',
'length' => 12,
'not null' => TRUE,
'default' => ''
),
'email' => array(
'type' => 'varchar',
'length' => 255,
'not null' => TRUE,
'default' => ''
),
'date_registered' => array(
'mysql_type' => 'DATETIME',
'not null' => TRUE
),
'primary' => array(
'rid'
)
)
);
return $schema;
}
which gives me the following errors
Notice: Undefined index: type in DatabaseSchema_mysql->processField() (line 205 of /Users/richardskinner/Sites/www.goldrushmoney.com-local/httpdocs/includes/database/mysql/schema.inc).

Been trying to find a solution for hours.
Thanks.

Answer 1

It is an issue with your primary key. You hve it listed in the fields array (it should not be) and it should be referenced as 'primary key' and not 'primary', like so:
function request_gold_pack_schema(){
$schema['request_gold_pack_customer_details'] = array(
'description' => 'Table to store all customer details.',
'fields' => array(
// Your field definitions
),
'primary key' => array(
'rid'
)
);
return $schema;
}
Check out the schema api documentation on drupal.org.
I would also recommend setting the rid field to type serial and leaving off the auto increment parameter (Drupal will handle that). So the 'rid' field definitions would be as such:
'rid' => array(
'type' => 'serial',
'unsigned' => TRUE,
'not null' => TRUE,
)

Answer 2

You have to specify the size in drupal 7 for type 'int'...i.e
'rid' => array(
'type' => 'int',
'not null' => TRUE,
'size' => 'normal',
'auto increment' => TRUE,
),
the size can be normal,tiny,big
check drupal 7 datatypes.
