=head1 DESCRIPTION
$beer->to_field($col, $args);
Not all _to_* methods pay attention to all arguments. For example, '_to_textfield' does not look in $args->{'items'} at all.
-
+
=over
=item name -- the name the element will have , this trumps the derived name.
$beer->to_field('brewery', 'readonly', {
- name => 'brewery_id'
+ name => 'brewery_id'
});
-
+
=item value -- the initial value the element will have, trumps derived value
$beer->to_field('brewery', 'textfield', {
name => 'brewery_id', value => $beer->brewery,
# however, no need to set value since $beer is object
});
-
+
=item items -- array of items generally used to make select box options
Can be array of objects, hashes, arrays, or strings, or just a hash.
$beer->to_field(rating => select => {
items => [1 , 2, 3, 4, 5],
});

+
# Select a Brewery to visit in the UK
Brewery->to_field(brewery_id => {
items => [ Brewery->search_like(location => 'UK') ],
This in almost always derived in cases where it may be difficult to derive, --
# Select beers to serve on handpump
Pub->to_field(handpumps => select => {
- class => 'Beer', order_by => 'name ASC', multiple => 1,
+ class => 'Beer', order_by => 'name ASC', multiple => 1,
});
=item column_type -- a string representing column type
-
+
$pub->to_field('open', 'bool_select', {
column_type => "bool('Closed', 'Open'),
});
Generally this can be set to get or not get a null/empty option added to
a select box. AsForm attempts to call "$class->column_nullable" to set this
and it defaults to true if there is no shuch method.
-
+
$beer->to_field('brewery', { column_nullable => 1 });
-=item r or request -- the mapyole request object
+=item r or request -- the Mapyole request object
=item uri -- uri for a link , used in methods such as _to_link_hidden
$beer->to_field('brewery', 'link_hidden',
- {r => $r, uri => 'www.maypole.perl.org/brewery/view/'.$beer->brewery});

# an html link that is also a hidden input to the object. R is required to
# make the uri unless you pass a uri
These are used in making select boxes. order_by is a simple order by clause
and constraint and join are hashes used to limit the rows selected. The
difference is that join uses methods of the object and constraint uses
-static values. You can also specify these in the relationship arguments.

Tell AsForm not to make hidden inputs for relationship constraints. It does

+*Function* to make sense out of the "selected" argument which has values of the
+options that should be selected by default when making a select box. It
+can be in a number formats. This method returns a map of which options to
+select with the values being the keys in the map ( {val1 => 1, val2 = 1} ).
-Below handles these formats for the "selected" slot in the arguments hash:
- Object (with id method)
- Scalar (assumes it is value)
- Array ref *OF* objects, arrays of data (0 elmnt used), hashes of data
- (id key used), and simple scalars.
-
+Currently this method handles the following formats for the "selected" argument
+and in the following ways
+ Object -- uses the id method to get the value
+ Scalar -- assumes it *is* the value
+ Array ref of objects -- same as Object
+ Arrays of data -- uses the 0th element in each
+ Hashes of data -- uses key named 'id'
