How I can get filters value from query string in (frappe.get_all filters)
as
{% set servdoc=frappe.get_all(‘Homepage Featured Product’,filters={ “item_code”:“WEB-ITM-0008”},

    fields=[ 'item_name' ,'description' , 'image'  ]) %}

instead “WEB-ITM-0008” I want take value from in url :
service_detail.html?item=WEB-ITM-0008
