Accessing lookup data from main context when in a component

yvonnegw-ics

Hi, another newbie.

I have a complex JSON structure for my data which includes lookup data - below is a simplified version

{
	"lkpCodes": {
		"SeverityLkp": {"0": "severity-0",	"1": "severity-1",	"2": "severity-2",	"3": "severity-3",	"4": "severity-4",	"5": "severity-5"	}
	},
	"Need": {
		"NeedId": "N00001363",
		"Assessments": {
			"A1": [{"period": "2023","severity": "1"},{"period": "2024","severity": "1"},{"period": "2025","severity": "2"},{"period": "2026","severity": "3"}],
			"A2": [{"period": "2023","severity": "0"},{"period": "2024","severity": "1"},{"period": "2025","severity": "2"},{"period": "2026","severity": "3"}],
			"A3":  [{"period": "2023","severity": "2"},{"period": "2024","severity": "2"},{"period": "2025","severity": "3"},{"period": "2026","severity": "4"}]
		}}
}

Depending on client requirements I need to show one or more of the assessments (ie might only want A2) so I call a component passing only the data for the required assessment

{{#with (lookup this.Need.Assessments 'A1') }}

        {{component "showAssessment" }}

{{/with}}

I need to use the severity value to lookup the class name from the SeverityLkp in lkpCodes but cant figure out how to access this from within the component. I thought i could get it from @root but this only holds the current data within the component (ie in this case the data for A1).

Thanks in advance

Similar is the main example and docs
https://playground.jsreport.net/w/admin/mcb0pE1a
https://jsreport.net/learn/components

In your case, it would be like this

{{#with (lookup this.Need.Assessments 'A1') }}
  {{component "showAssessment"  lkpCodes=@root.lkpCodes }}
{{/with}}

In other words, you can pass anything from the root and also the whole root in the extra attribute.

Thank you so much - that is working perfectly now.
