Hello Daniel,
I guess I'd do something like
---8<---
# app/controller/witness_report.rb
class WitnessReportController
def update
report = Report.find(params[:id])
# update report ...
if report.all_the_reports_for_that_case_have_been_received
# unleash the flow
workitem = RuoteKit.engine.storage_participant.by_participant(
'receive_witness_reports'
).find { |wi|
wi.wfid == report.wfid
}
# grab our waiting workitem
workitem.fields['report_count'] = report.all_the_reports_count
# some additional info before proceeding
RuoteKit.engine.storage_participant.proceed(workitem)
# the flow will resume after 'receive_witness_reports'
end
end
end
--->8---
or
---8<---
workitem = RuoteKit.engine.storage_participant.by_wfid(
report.wfid
).find { |wi|
wi.participant_name == 'receive_witness_reports'
}
--->8---
depending on the expected load. This second variant is probably better, less
iterating.
(of course, I guess you'd put it all this jazz in the Report class).
I hope it helps, best regards,
