Getting filter value in script report

I want to get my filter value from .js file into script file (.py) file in my query but i couldn’t get it… anyone could help me please

def get_data(filters):
campaign_Name = filters.get(‘campaign_name’)
contest = frappe.db.sql(""“SELECT contest_type FROM tabProperty Sales Campaign WHERE campaign_name = %s”"",campaign_name,as_dict=True)
its my python function, at start i just want to get my filter value in that query

To set filters in js:

frappe.query_reports["Some Report Name"] = {
	"filters": [
			"label": __("Supplier"),
			"fieldtype": "Link",
			"options": "Supplier"

To use it in python:

class SomeReportName(object):
	def __init__(self, filters=None):
		self.filters = frappe._dict(filters or {})

Then, you can use them as : self.filters[“supplier”]

can you elaborate this…plz

how to implement in server side?

Have a look at [Tutorial] Script Report / Chart where I use filters extensively.
