How It Works

Three screens - the engine has no requests of its own.

1

Every type, with its load

One card per type, counting what is waiting and what has been approved.

Approval overview
2

The types themselves

Purchase orders, contracts, deliveries, general requests - each with its own rule.

Approval types
3

One type, in full

Approvers in sequence, the minimum number of approvals, the deadline, and what the request must carry.

An approval type and its approvers

What You Get

Approval types per company, each with its own approver lines

Sequential approval, or several approvers at the same step

A minimum number of approvals, with a warning when it is exceeded

A deadline in days, and a manager-approval mode

What a request must carry: document, amount, date, location, partner, period

An approval-state mixin any model can inherit, plus a searchable current state

An overview counting requests waiting and approved per type

What This App Does Not Do

Read this before you buy. Everything below is something the app deliberately leaves to another app or to you.

It is an engine, not an app.

The requests themselves come from OmniApproval and the apps that route through it.

It does not approve documents by itself.

A document opts in through the state mixin; that link is the app's job, not the engine's.

Conditions are Python expressions, for administrators.

A condition on a step is evaluated in a restricted sandbox and is meant for a configurator, not an end user.

One company's types do not apply to another.

Types are company-scoped, deliberately - approval routes rarely survive a border.

Works Well With

Apps from the same stack, built to fit this one:

OmniApproval

The request app built on this engine.

viin_approval

Procurement Approval

Purchasing routed through it.

to_procurement_approval

Maintenance Approval

Maintenance requests routed through it.

to_maintenance_approval

Who Should Use Approvals?

Administrator

Defines the routes once, instead of asking for a developer per app.

Approver

Gets requests in the order the type says, not all at once.

Requester

Sees where the request stands and who is holding it.

Auditor

Reads the rule that was in force and the trail it produced.
