decisionrulespy 2.0.5

A simple library for simple connecting to DecisionRules API

DecisionRulesPy

A simple library that allows you to easily connect to DecisionRules.io from your application.

Usage

• Solver (Rules, Compositions)
• Management API

1 - Solver

Solver is designed for solving rules made in DecisionRules application. You can run solver with decisionrules.solver() method. Rule ids are accessible in DecisionRules app.

1.1 - Defining solver init

Solver need some data beforehand, like api keys

from decisionrules import *

async def solver_test():
    decisionrules.init(api_key)

1.2 - Defining solver method with data

Solver method expects 5 arguments

• SolverType - enum value - mandatory
• RuleId - str - mandatory
• Data - dict or json str - mandatory
• SolverStrategy - enum value - mandatory
• Version - str - optional

async def solver_test():
    data = {"say": "Hello from python"}

    decisionrules.init(api_key)
    
    # SolverType enum changes type of solver (Rule or Compostion)
    response = await decisionrules.solver(decisionrules.SolverType.RULE, get_rule, data, SolverStrategies.STANDARD)

    response2 = await decisionrules.solver(decisionrules.SolverType.RULEFLOW, compo_rule, data, SolverStrategies.STANDARD)

1.3 Solver with custom domain

For using custom domain just add CustomDomain instance to the init method with url and protocol parameters.

async def solver_test():
    data = {"say": "Hello from python"}

    decisionrules.init(api_key, CustomDomain("YOUR_URL", Protocols.HTTPS))
    
    response = await decisionrules.solver(decisionrules.SolverType.RULE, get_rule, data, SolverStrategies.STANDARD)

    response2 = await decisionrules.solver(decisionrules.SolverType.COMPOSITION, compo_rule, data, SolverStrategies.STANDARD)

2 - Management API

Management api is accessible via dr_management and required management api key that you can obtain in api key section in DecisionRules app. Management api key is defined in custom dr_management init method.

async def crud_test():
    dr_management.init(mng_key)

2.1 Management API usage example

from decisionrules import *

async def crud_test():
    dr_management.init(mng_key)

    get_rule_resp = await dr_management.get_rule_by_id(get_rule)
    get_rule_by_version_resp = await dr_management.get_rule_by_id_and_version(get_rule, "1")
    get_space_resp = await dr_management.get_space(get_space)

    await dr_management.put_rule(put_rule, "1", put_data)
    await dr_management.post_rule(post_rule, post_data)
    await dr_management.delete_rule(delete_rule, "1")

2.3 All available methods in management API

• GetRuleById - Search for single rule by its ID
• GetRuleByIdAndVersion - Search for single rule by its ID and version
• GetSpace - Search for space by its ID
• PostRuleForSpace - Post new rule to the space
• PutRule - Update existing rule
• DeleteRule - Delete existing rule

dr_management.get_rule_by_id(get_rule)

dr_management.get_rule_by_id_and_version(get_rule, "1")

dr_management.get_space(get_space)

dr_management.put_rule(put_rule, "1", put_data)

dr_management.post_rule(post_rule, post_data)

dr_management.delete_rule(delete_rule, "1")
