jifty::collection
Jifty::Collection(3pm) User Contributed Perl Documentation Jifty::Collection(3pm)
NAME
Jifty::Collection - Collection of Jifty::Record objects
SYNOPSIS
package Foo::Model::BarCollection
use base qw/Jifty::Collection/;
DESCRIPTION
This is a wrapper over Jifty::DBI::Collection that at the same time is a Jifty::Object. To use it, subclass it.
Alternatively, an 'anonymous' collection can be made by creating a new "Jifty::Collection" object, and calling
"record_class('Application::Model::Foo')" or similar on it.
In addition, each Jifty::Collection includes a Data::Page object to help with calculations related to paged data. You should not call the
"first_row" and "rows_per_page" methods from Jifty::DBI::Collection on a Jifty::Collection. Instead, if you'd like to use paging, you
should use the "set_page_info" method to set the number of records per page and first record on the current page, and you should use the
Data::Page object returned by the "pager" method to get information related to paging.
MODEL
pager
Returns a Data::Page object associated with this collection. This object defaults to 10 entries per page. You should use only use
Data::Page methods on this object to get information about paging, not to set it; use "set_page_info" to set paging information.
results_are_readable
If your results from the query are guaranteed to be readable by current_user, you can create the collection with "results_are_readable =>
1". This causes check_read_rights to bypass normal current_user_can checks.
as_search_action PARAMHASH
Returns the Jifty::Action::Record::Search action for the model associated with this collection.
The PARAMHASH allows you to add additional parameters to pass to "new_action" in Jifty::Web.
add_record
If "results_are_readable" is false, only add records to the collection that we can read (by checking "check_read_rights" in Jifty::Record).
Otherwise, make sure all records added are readable.
implicit_clauses
Defaults to ordering by the "id" column.
jifty_serialize_format
This returns an array reference of the individual records that make up this collection.
