Inputs

The workflow model can define input schema to constrain the variables passed when starting a workflow.

Input Schema

Uses JSON Schema format to define the input schema:

id: my_model
name: test
inputs:
  type: object
  properties:
    a:
      type: integer
      default: 10
    user_name:
      type: string
  required:
    - a

Passing Inputs When Starting

#![allow(unused)]
fn main() {
use acts::{Engine, Principal, Vars, Workflow};

let engine = Engine::builder().start().await.unwrap();
let executor = engine.executor(&Principal::unrestricted());

let mut vars = Vars::new();
vars.set("a", 100);
vars.set("user_name", "admin");
executor.proc().start("my_model", vars)?;
}

Dynamic Input Setting

You can set the inputs value using ModelBuilder:

#![allow(unused)]
fn main() {
use acts::model::Workflow;

let mut workflow = Workflow::new("my_model", "my workflow")
    .set_inputs(serde_json::json!({
        "type": "object",
        "properties": {
            "a": { "type": "integer" },
            "b": { "type": "string" }
        }
    }));
}

Step Inputs

Input data can also be received at the step level:

steps:
    - id: step1
      vars:
        - name: local_var
          value: '${{ inputs.a }}'
