Question

在rails c中使用它时工作

client = TwitterSearch::Client.new('campvote')

tweets = client.query('#barcampmlk2 #railsforzombies +1')

但不是BarcampSession.update_twitter!它重新调整空哈希

require 'twitter_search'
class BarcampSession < ActiveRecord::Base
    validates :hash_tag , :format => {:with => /^#\w+/ } , :presence => true ,:uniqueness => true
    validates :name , :presence => true 
    validates :email , :presence => true , :format => {:with => /((\S+)@(\S{3}[a-zA-z0-9)]\S*))/ }
    validates :handphone, :presence => true 

    def self.update_twitter!
        client = TwitterSearch::Client.new('campvote')
        BarcampSession.all.each do |sess|
            tweets = client.query('#barcampmlk2 #{sess.hash_tag} +1')
            puts tweets.to_yaml
        end

    end
end

它返回

rb(main):014:0> BarcampSession.update_twitter!
--- !seq:TwitterSearch::Tweets []

=> [#<BarcampSession id: 1, hash_tag: "#railsforzombies", name: "wizztjh", email: "wiz123tjh@gmail.com", handphone: "1234006", since: nil, created_at: "2010-12-14 18:28:01", updated_at: "2010-12-14 18:28:01">]

Answer 1

字符串插值仅适用于双引号，而不适用于单引号。改变行

tweets = client.query('#barcampmlk2 #{sess.hash_tag} +1')

到

tweets = client.query("#barcampmlk2 #{sess.hash_tag} +1")

Twitter搜索API的问题
