Module: RailsWorkflow::OperationTemplates::Dependencies

Extended by:: ActiveSupport::Concern
Included in:: RailsWorkflow::OperationTemplate
Defined in:: app/concerns/rails_workflow/operation_templates/dependencies.rb

Overview

Dependencies

Operation Template includes operation dependencies description. Example:

Operation A depends on operation B in DONE status then
operation A will be created when operation B will get DONE status.

If operation depends on few statuses of other operation:

Operation A depends on operation B in DONE and IN_PROGRESS statuses then
operation A will be created when operation B will get DONE or IN_PROGRESS status.

If operation depends on few other operations

Operation A depends on operation B in DONE status or operation C in IN_PROGRESS status then
operation A will be created when
  operation B gets DONE status
    (no matter if operation C exists and has IN_PROGRESS status or not)
  or operation C gets IN_PROGRESS status
    (no matter if operation B exists and has DONE status or not)

This is default behaviour. You can customize it using #resolve_dependencies method

Independen operations is operations with no dependencies. When process manager building new process, that process building it's independent operations. When process manager starts process, process starts it's independent operations.

Instance Method Summary (collapse)

- (Array) dependencies

Returns operation template dependecies.
- (boolean) resolve_dependency(operation)

This method allows you to define custom dependencies conditions.
