RML Reports summation of answers columns
I have edited the survey.answer and add a POINTS field.. What I need to do is, when a user answer a question. their is a corresponding point for that, the formula is response * points but then i need to get the sum of all answer, it means i need to have this formula * sum(response * points )* .. I dont know how to do this summation of columns in survey.answer
Hello lhadiesleo
you can use field.function() which will do the calculation at run time and print the result in your desire field.
py file class survey_answer:
def _my_point_sum():
calculate your sum here
columns={
'function' : fields.function(
_my_point_sum,
type='char',
string='Points'),
}
I already do that but it is not working, it still gets the value in the last line of the column,
