How to pass HashMap values as a queryParam to Gatling simulation - scala

Question

I need help for passing HashMap to queryParam as shown below, as I have so many request with same queryParams and just last queryParam changes with each request.
val asset_sort_by_displays = exec(http("Sort by Displays")
.get("/data/analytics/reports/")
.queryParamMap(GatlingConfig.asset_query_string_map)
.queryParam("""sort""", """displays""")
Where in my config file I have a object GatlingConfig{} where I've defined asset_query_string_map as.
val asset_query_string_map = Map("""report_type""" -> """performance""",
"""start_date""" -> "2014-07-07",
"""end_date""" -> "2014-07-10",
"""metrics""" -> """plays""",
"""metrics""" -> """displays""",
"""metrics""" -> """video_starts""")
But, it throws " value asset_query_string_map is not a member of io.gatling.http.request.builder.HttpRequestBuilder " error.
Please guide me , how can I pass Map value to queryParams?

Where in my config file I have created
I don't get it. This is to be defined in some Scala code and imported/placed in scope.
Then, queryParam is for unique values. You'd have to use queryParamMap instead.
With current snapshot, you'd have:
val asset_query_string_map = Map("""report_type""" -> """performance""",
"""start_date""" -> "2014-07-07",
"""end_date""" -> "2014-07-10",
"""metrics""" -> """plays""",
"""metrics""" -> """displays""",
"""metrics""" -> """video_starts""")
val asset_sort_by_displays = exec(http("Sort by Displays")
.get("/data/analytics/reports/")
.queryParamMap(asset_query_string_map)
.queryParam("""sort""", """displays"""))
