ruby on rails - What are query_parameters and how do I pass them to Tweetstream::Client...filter(query_parameters = {}) -

i using tweetstream gem retrieve statuses twitter. works:

 tweetstream::client.new('user', 'pw').track('alice', 'wonderland')  

however, know want limit collecting tweets both (i) specific users (ii) specific words. tweetstream gem provides method:

 tweetstream::client.new('user', 'pw').filter(query_params = {}, &block) 

but can't figure out how pass query_parameters = {}. i'm trying this:

 tweetstream::client.new('user', 'pw').filter(                {:follow => ('212380730', '23234252'),                  :track => ('alice', 'wonderland')                 } )  

but errors related syntax, e.g.,

syntax error, unexpected tsymbeg, expecting '}'

thank help!

the following tweetstream rdoc: filter(query_params = {}, &block)

make call statuses/filter method of streaming api, may provide :follow, :track or both options follow tweets of specified users or track keywords. method provided separately cases when conserve number of http connections combine track , follow.

this source of .filter method:

 def filter(query_params = {}, &block)    [:follow, :track].each |param|    if query_params[param].is_a?(array)    query_params[param] = query_params[param].collect{|q| q.to_s}.join(',')      elsif query_params[param]        query_params[param] = query_params[param].to_s      end    end    start('statuses/filter', query_params.merge(:method => :post), &block)  end 

i think mean [] instead of using () filter , track, :filter , :track in query params supposed arrays
