Expressions

Three types of expressions can be used within a Workspaces configuration:

  • env variables
  • dynamic variables
  • helper functions

Env variables​

Env variables are interpolated as soon as the JSON is received on the client.

UsageSupported variables
{{ variable }}currentUser, currentQueue
Example
"filterBy": { 
    "$assigned": "{{ currentUser }}" 
}

Dynamic variables​

Dynamic variables are interpolated at runtime.

UsageSupported variables
${ variable }applicant.key
Example
"$qualfile": {
    "label": "Qualfile",
    "dataIndex": "properties['FisQualiFile.${ applicant.key }.accountAcceptanceTxt']",
    "type": "text",
    "link": {
        "dataIndex": "properties['FisQualiFile.${ applicant.key }.htmlReport']",
        "type": "html"
    }
},
"dataIndex": "properties['FisQualiFile.${ applicant.key }.accountAcceptanceTxt']"

Helper functions​

Helper functions are expressions that can be used within the JSON configuration to generate dynamic values.

date()​

The date function is useful when a developer needs to define a date. Absolute and relative dates can be defined easily using natural language.

Usage
{{ date('natural language') }}
