how to get base chart.yaml version from sub charts

Question

I have an umbrella chart, it has a template for almost all subcharts deploymentConfig. how do i get the base chart version from the subchart.

maybe a solution will be to overwrite sub charts chart.yaml version but i tried to do that too without success.

i tried _helpers.tpl on the base chart and to define on my _deployment-config.yaml on base chart

{{- define "bitcore.deployment" -}}
{{- $common := dict "Values" .Values.bitcore -}} 
{{- $noCommon := omit .Values "bitcore" -}} 
{{- $overrides := dict "Values" $noCommon -}} 
{{- $noValues := omit . "Values" -}} 
{{- with merge $noValues $overrides $common -}}

          - name: JAVA_OPTS

          failureThreshold: 10
        resources:
          {{- toYaml .Values.global.resources | nindent 12 }}
        volumeMounts:
          - mountPath: /logs

      volumes:

        emptyDir: {}
  test: false
{{- end -}}
{{- end -}}

i excpected complicated version(7.0.0-snapshot-dev-872), but i got the subchart version 0.1.0

I don't think you can access the .Chart of the superchart, anywhere, anyhow. After all, the subcharts are supposed to still be able to work as stand-alone.

The best you can do with helm 2 is to put the version in the .Values.global section.

In helm 2, you have to write it to the top-level values.yaml in the script that generates the version, because you can't have any code there. I believe in helm 3 it should be possible to generate values by script.
