我想在数据库中存储一个大的json响应，并且稍后想要解析该json。但问题是如何在不丢失实际格式的情况下将json存储在db中。当我将它作为ruby中的文本存储在rails上时，在获取错误（即无效的Json）时提取。

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

Rake任务： -

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

需要序列数据。看看这个：http://edgerails.info/articles/what-s-new-in-edge-rails/2011/03/09/custom-activerecord-attribute-serialization/index.html

Answer 2

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