61 my $object = my $object = SL::DB::Manager::Part->get_first;

64 see also L<SL::Presenter>
74 =item C<part, $object, %params>
76 Returns a rendered version (actually an instance of
77 L<SL::Presenter::EscapedText>) of the part object C<$object>
79 C<%params> can include:
85 Either C<inline> (the default) or C<table-cell>. At the moment both
86 representations are identical and produce the part's name linked
87 to the corresponding 'edit' action.
95 =item C<part_picker $name, $value, %params>
97 All-in-one picker widget for parts. The name will be both id and name
98 of the resulting hidden C<id> input field (but the ID can be
99 overwritten with C<$params{id}>).
101 An additional dummy input will be generated which is used to find
102 parts. For a detailed description of it's behaviour, see section
103 C<PART PICKER SPECIFICATION>.
105 C<$value> can be a parts id or a C<Rose::DB:Object> instance.
107 If C<%params> contains C<type> only parts of this type will be used
108 for autocompletion. You may comma separate multiple types as in
111 If C<%params> contains C<unit> only parts with this unit will be used
112 for autocompletion. You may comma separate multiple units as in
115 If C<%params> contains C<convertible_unit> only parts with a unit
116 that's convertible to unit will be used for autocompletion.
118 Obsolete parts will by default not displayed for selection. However they are
119 accepted as default values and can persist during updates. As with other
120 selectors though, they are not selectable once overridden.
122 Currently you must include C<js/autocomplete_part.js> in your controller, the
123 presenter can not do this from the template.
127 =head1 PART PICKER SPECIFICATION
129 The following list of design goals were applied:
135 Parts should not be perceived by the user as distinct inputs of partnumber and
136 description but as a single object
140 Easy to use without documentation for novice users
144 Fast to use with keyboard for experienced users
148 Possible to use without any keyboard interaction for mouse (or touchscreen)
153 Must not leave the current page in event of ambiguity (cf. current select_item
158 Should be useable with hand scanners or similar alternative keyboard devices
162 Should not require a feedback/check loop in the common case
166 Should not be constraint to exact matches
170 The implementation consists of the following parts which will be referenced later:
176 A hidden input (id input), used to hold the id of the selected part. The only
177 input that gets submitted
181 An input (dummy input) containing a description of the currently selected part,
182 also used by the user to search for parts
186 A jquery.autocomplete mechanism attached to the dummy field
190 A popup layer for both feedback and input of additional data in case of
195 An internal status of the part picker, indicating wether id input and dummy
196 input are consistent. After leaving the dummy input the part picker must
197 place itself in a consistent status.
201 A clickable icon (popup trigger) attached to the dummy input, which triggers the popup layer.
