我想在數據庫中存儲一個大的json響應，並且稍後想要解析該json。但問題是如何在不丟失實際格式的情況下將json存儲在db中。當我將它作爲ruby中的文本存儲在rails上時，在獲取錯誤（即無效的Json）時提取。

venue_list = VenuesList.create(:response=>@response) /@response is the json above. 
call_rake :parse_venue, :venue_list_id => venue_list.id 

Rake任務： -

task :parse_venue => :environment do 
venue_list = VenuesList.find(ENV["VENUE_LIST_ID"]) 
p response = venue_list.response // here this return invalid JSON.I tested the response on http://jsonlint.com/ 

response['response']['groups'][0]['items'].each do |venue| // here this return invalid JSON. 

    p venue['name'] 
    p venue['location']['address'] 
    //........ 
end 
end

Answer 1

需要序列數據。看看這個：http://edgerails.info/articles/what-s-new-in-edge-rails/2011/03/09/custom-activerecord-attribute-serialization/index.html

Answer 2

也許你可以使用Marshal.dump（）和更高版本的Marshal.load（）。
