Unknown method "list_interest_groupings/first"

[jai-n]

I have initialize my mailchimp object but when i try to get grouping_id igot following error
(rdb:34) mc.grouping_id
*** Gibbon::MailChimpError Exception: MailChimp API Error: Unknown method "list_interest_groupings/first" (code -32601)

Can you paste a code snippet?

Looks like you're doing something like

mc.list_interest_groupings.first

Given the documentation for the call I think you're trying to make, try something like

mc.lists.list_groupings(params)

I have doing like this
def grouping_id
@grouping_id ||= client.list_interest_groupings(:id => mailing_list_id).first['id']
end
when I have try to like client.lists.list_groupings(:id => mailing_list_id) this then got following error
Gibbon::MailChimpError Exception: MailChimp API Error: Unknown method "lists/list-groupings" (code -32601)

I think you're using syntax from an older version of Gibbon (<=0.4.6_ with the new version of Gibbon (>=0.5.0, see the README for more info on the syntax change). The example I gave above should work for you.

No I have follow your new gibbon instruction but found error
i have use just like this
gb = Gibbon::API.new
gb.lists.list_groupings(:id=>"147a8d638d")
*** Gibbon::MailChimpError Exception: MailChimp API Error: Unknown method "lists/list-groupings" (code -32601)
you have any idea about it

It should be list_groupings, not "list_groupings" -- see the API docs for version 2 http://apidocs.mailchimp.com/api/2.0/

Can't solve my issue
I am not using "list_groupings", instead of list_groupings
finally I am using old gem gibbon -v 0.3.5 and my issue was resolved
Thanks Amro
