Re: [web2py] Re: Workflow engine for web2py
My workflow got pushed to the back burner. Right now I have so much on my plate I don't know when I'll get back to it.

Re: [web2py] Re: Workflow engine for web2py
Not sure how relevant it is but some time ago I made this: https://github.com/mdipierro/workflow It is not web2py specific and it is designed for file-based workflow. It can be used with web2py in the sense that it can run web2py background tasks. It could be improved by reading the state and the rules directly from the dal. massimo On Monday, 24 September 2012 08:37:24 UTC-5, Patrick wrote: This survey couid inspire someone http://snarfed.org/workflow_software_survey --

Re: [web2py] Re: Workflow engine for web2py
Any evolution in this issue. I need it bad. I was thinking in workflow as a service. Instead of changing dal i would submit the record to a webservice verification service that returns a new record, changed according to the rules. Is this a good thinking? and easier to do?

Re: [web2py] Re: Workflow engine for web2py
No progress here I didn't have time for that... I involve in any initiative, but we need orientation. I think we should try something (anything) that could work and see what are the limitation of the approach and try other approach (trial and error)...
