SL::Presenter::Part - Part related presenter stuff
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
# Create an html link for editing/opening a part/service/assembly
|
|
my $object = my $object = SL::DB::Manager::Part->get_first;
|
|
my $html = SL::Presenter->get->part($object, display => 'inline');
|
|
|
|
see also L<SL::Presenter>

|
|
|
|
see L<SL::Presenter>

|
=head1 FUNCTIONS

|

|
=item C<part, $object, %params>
|
|
|
|
Returns a rendered version (actually an instance of
|
|
L<SL::Presenter::EscapedText>) of the part object C<$object>
|
|
|
|
C<%params> can include:
|
|
|
|
=over 4
|
|
|
|
=item * display
|
|
|
|
Either C<inline> (the default) or C<table-cell>. At the moment both
|
|
representations are identical and produce the part's name linked
|
|
to the corresponding 'edit' action.

|
|
|
|
=item C<part_picker $name, $value, %params>
|
|
|
|
All-in-one picker widget for parts. The name will be both id and name
|
|
of the resulting hidden C<id> input field (but the ID can be
|
|
overwritten with C<$params{id}>).
|
|
|
|
An additional dummy input will be generated which is used to find
|
|
parts. For a detailed description of it's behaviour, see section
|
|
C<PART PICKER SPECIFICATION>.
|
|
|
|
C<$value> can be a parts id or a C<Rose::DB:Object> instance.
|
|
|
|
If C<%params> contains C<type> only parts of this type will be used
|
|
for autocompletion. You may comma separate multiple types as in
|
|
C<part,assembly>.
|
|
|
|
If C<%params> contains C<unit> only parts with this unit will be used
|
|
for autocompletion. You may comma separate multiple units as in
|
|
C<h,min>.
|
|
|
|
If C<%params> contains C<convertible_unit> only parts with a unit
|
|
that's convertible to unit will be used for autocompletion.
|
|
|
|
Obsolete parts will by default not displayed for selection. However they are
|
|
accepted as default values and can persist during updates. As with other
|
|
selectors though, they are not selectable once overridden.
|
|
|
|
Currently you must include C<js/autocomplete_part.js> in your controller, the
|
|
presenter can not do this from the template.

=head1 PART PICKER SPECIFICATION
|
|
|
|
The following list of design goals were applied:
|
|
|
|
=over 4
|
|
|
|
=item *
|
|
|
|
Parts should not be perceived by the user as distinct inputs of partnumber and
|
|
description but as a single object
|
|
|
|
=item *
|
|
|
|
Easy to use without documentation for novice users
|
|
|
|
=item *
|
|
|
|
Fast to use with keyboard for experienced users
|
|
|
|
=item *
|
|
|
|
Possible to use without any keyboard interaction for mouse (or touchscreen)
|
|
users
|
|
|
|
=item *
|
|
|
|
Must not leave the current page in event of ambiguity (cf. current select_item
|
|
mechanism)
|
|
|
|
=item *
|
|
|
|
Should be useable with hand scanners or similar alternative keyboard devices
|
|
|
|
=item *
|
|
|
|
Should not require a feedback/check loop in the common case
|
|
|
|
=item *
|
|
|
|
Should not be constraint to exact matches
|
|
|
|

|
|
|
|
The implementation consists of the following parts which will be referenced later:
|
|
|
|
=over 4
|
|
|
|
=item 1
|
|
|
|
A hidden input (id input), used to hold the id of the selected part. The only
|
|
input that gets submitted
|
|
|
|
=item 2
|
|
|
|
An input (dummy input) containing a description of the currently selected part,
|
|
also used by the user to search for parts
|
|
|
|
=item 3
|
|
|
|
A jquery.autocomplete mechanism attached to the dummy field
|
|
|
|
=item 4
|
|
|
|
A popup layer for both feedback and input of additional data in case of
|
|
ambiguity.
|
|
|
|
=item 5
|
|
|
|
An internal status of the part picker, indicating wether id input and dummy
|
|
input are consistent. After leaving the dummy input the part picker must
|
|
place itself in a consistent status.
|
|
|
|
=item 6
|
|
|
|
A clickable icon (popup trigger) attached to the dummy input, which triggers the popup layer.
