edc-form-label

Customize Django's form label in realtime

For a sequence of data collection timepoints, we ask the question, "Are you circumcised?". At some time point we hope the response will be YES, but until then, we need to ask "Since we last saw you, were you circumcised?". It is a lot better if we can ask, "Since we last saw you in 'October 2018', were you circumcised?", where 'October 2018' represents the timepoint from which we got our last reponse.

This module shows how you can insert 'October 2018' into the ModelAdmin/ModelForm the form label in realtime.

For example:
