The
Request
QOur
art
faculty
use
our
site,
Trove,
to
create
collections
of
images
for
use
in
class,
and
they’d
like
to
order
the
images
in
the
collection
however
they
want,
for
class.
The
Problem
Fedora
4
will
be
too
performance
heavy
to
manage
arbitrary
sorting
of
hundreds
of
works
and
subcollections.
So
we
have
to
use
something
else.
The
Solution
Use
ActiveRecord
to
store
the
list
of
ids,
accessible
as
a
Rails
model.
Hook
into
dashboards
to
update
our
collection
order
arrays
when
item
membership
changes.
Alter
solr
queries
on
collection
pages
to
retrieve
all
records,
and
re-order
as
necessary.

Implementation*
1.
Create
a
migration
and
model
to
store
a
list
of
ids
as
an
array
in
the
db,
and
create
a
module
that
saves
and
retrieves
orders
from
the
Collection
objects.
{app/models/collection_order.rb
db/migrate/create_collection_orde
rs.rb
app/models/concerns/collection_or
der_support)
2.
Create
routes/methods
for
updating
CollectionOrders,
and
find
the
places
you'll
need
to
patch
to
insert
item-order
updating.
{config/routes.rb
app/controllers/hyrax/dashboard/c
ollections_controller.rb)
Add
a
mechanism
in
the
edit
collection
view
to
allow
users
to
order
the
works
manually.
We
used
jQuery
Ul
Sortable
to
create
an
AJAX
interface.
(/app/assets/javascripts/sortable-wo
rks,
/app/assets/javascripts/sortable-sub
collections)
Extend
Hyrax::Collections:
:CollectionMember
Service
and
alter
query_solr
to
retrieve
all
works
and
then
obey
the
CollectionOrder.
