How to get other data like count of returned data and total data in frappe call (parameters). I am actually using datatable and customizing the parameters with frappe call but can’t get enough help out on internet.
Frappe call doesnt return the count of data.
You could try r.message.length instead if that is your requirement 
If you could be more descriptive, I could try to help you more.
Trying to get the total count and displayed count of data displayed by ajax datatable.
Also, was thinking of overriding it with the frappe’s parameter
any suggestions ??
