metadata_hash

Items support accessing metadata from different files

    • Given Clean OpenHAB with latest Ruby Libraries
    • And items:
      typename
      SwitchTestSwitch
    • And a deployed rule:
      TestSwitch.meta['animalsounds'] = { 'land' => { 'cow' => 'moo'}}
logger.info("Metadata animalsounds created for TestSwitch: #{TestSwitch.meta['animalsounds']}")

  • Metadata key works when assigned in the same rule

    • Given code in a rules file:
      TestSwitch.meta['animalsounds'] = {"land"=>{"cow"=>"moo"}}
code = '<metadata>'
logger.info("#{code}: #{<metadata>}")
    • When I deploy the rules file
    • Then It should log '<metadata>: <value>' within 5 seconds

    Examples:

    metadata value
    TestSwitch.meta["animalsounds"] {"land"=>{"cow"=>"moo"}}
    TestSwitch.meta.dig("animalsounds", "land") {"cow"=>"moo"}
    TestSwitch.meta.dig("animalsounds", "land", "cow") moo

  • Metadata key works when not assigned in the same rule

    • Given code in a rules file:
      code = '<metadata>'
logger.info("#{code}: #{<metadata>}")
    • When I deploy the rules file
    • Then It should log '<metadata>: <value>' within 5 seconds

    Examples:

    metadata value
    TestSwitch.meta["animalsounds"] {"land"=>{"cow"=>"moo"}}
    TestSwitch.meta.dig("animalsounds", "land") {"cow"=>"moo"}
    TestSwitch.meta.dig("animalsounds", "land", "cow") moo

  • Comparing against a hash literal when metadata assigned in the same rule

    • Given code in a rules file:
      TestSwitch.meta['animalsounds'] = {"land"=>{"cow"=>"moo"}}
logger.info("Metadata checks out") if <metadata> == <value>
    • When I deploy the rules file
    • Then It should log 'Metadata checks out' within 5 seconds

    Examples:

    metadata value
    TestSwitch.meta["animalsounds"] {"land"=>{"cow"=>"moo"}}
    TestSwitch.meta.dig("animalsounds", "land") {"cow"=>"moo"}
    TestSwitch.meta.dig("animalsounds", "land", "cow") "moo"

  • Comparing against a hash literal when metadata NOT assigned in the same rule

    • Given code in a rules file:
      logger.info("Metadata checks out") if <metadata> == <value>
    • When I deploy the rules file
    • Then It should log 'Metadata checks out' within 5 seconds

    Examples:

    metadata value
    TestSwitch.meta["animalsounds"] {"land"=>{"cow"=>"moo"}}
    TestSwitch.meta.dig("animalsounds", "land") {"cow"=>"moo"}
    TestSwitch.meta.dig("animalsounds", "land", "cow") "moo"

  • Calling to_json on metadata config

    • Given a deployed rule:
      TestSwitch.meta['animalsounds'] = { 'land' => <value> }
    • And code in a rules file:
      require 'json'
logger.info("Metadata to_json: #{TestSwitch.meta.dig("animalsounds", "land").to_json}")
    • When I deploy the rules file
    • Then It should log 'Metadata to_json: <json>' within 5 seconds

    Examples:

    value json
    {'cow'=>'moo'} {"cow":"moo"}
    [{'cow'=>'moo'},{'sheep'=>'baa'}] [{"cow":"moo"},{"sheep":"baa"}]
