Reporting against process task progress

[Damon Torgerson]

Hi,

I've been looking for a few hours and can't seem to find what is probably very basic.

I would like to report on all the processes that are currently in a particular state.

For example, given this process defintion

    p = Ruote.process_definition :name => 'Transfer' do

      sequence do

        reviewer :task => 'verify information', :description => 'Verify basic information'

        approver :task => 'assign transfer', :description => "Select the location"

        reviewer :task => 'confirm transfer', :description => 'Admin approval or denial.'

        email_system :task => 'email approval letter', :if => '${f.state} == approved', :description => 'Approval email'

      end

    end

I would like to know how many processes are waiting to have information verified, a transfer assigned, or a transfer confirmed.

Eg.

verify information: 20,

assign transfer: 30,

confirm transfer: 40

It seems that using the by_field method in storage participant helps me achieve this outcome but I can't figure it out. It seems like this is pretty straightforward stuff. What am I missing?

Really enjoying Ruote and all the efforts put into the project!

Sincerely,

Damon

Hello Damon,

I've played with a gist: https://gist.github.com/2592808

Effectively, you can't state "params.task" has the #by_field first argument.

I will add a #by_param to the storage participant. For your first question
I'd suggest using the technique shown in the gist.

Please tell me if it doesn't match your requirements or if your storage is
unhappy with that.


I hope it will help, best regards,

John,

Thank you so much for this! I was really just looking for a pointer to an existing function or "it doesn't exist...sorry" and would have been happy to muddle through. Not only did you go above and beyond but you provided me an improved understanding of ruote.

Thanks again!

Sincerely,

Damon
