Template::Iterator::AlzaboWrapperCursor - Turns a Class::AlzaboWrapper::Cursor object into a TT2 iterator
my $users = Template::Iterator::AlzaboWrapperCursor->new($cursor); # pass $users to a template my $users_with_pages = Template::Iterator::AlzaboWrapperCursor->new($users_with_pages);
In a template:
[% FOREACH user = users %] Name: [% user.name %]<br /> [% END %] [% FOREACH user_with_page = users_with_pages %] [% user_with_page.user.name %]: [% user_with_page.page.title %] [% END %]
This module allows a Class::AlzaboWrapper::Cursor object to be used as a TT2 iterator.
Class::AlzaboWrapper::Cursor
For a cursor which returns one object at a time, the iterator simply returns one object per iteration. When the cursor returns multiple objects, the iterator returns a hash reference where the keys are the table name of the object's class in lower-case, with camel-casing turned into underscores. The values of the hash are the objects.
So if the cursor returns Foo::User and Foo::Page objects, the keys are "user" and "page".
Foo::User
Foo::Page
This class provides the following methods:
This method accepts a Class::AlzaboWrapper::Cursor object and returns an iterator suitable for use in TT2 templates.
I wish that TT2 allowed multiple assignment in FOREACH loops so we could just do this:
FOREACH
[% FOREACH user, page = users_with_pages %]
That's so much cleaner.
