我想在数据库中存储一个大的json响应，然后想要解析那个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。当我将它作为文本存储在轨道上的ruby中时，在获取时我收到错误即无效的Json。

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

佣金任务： -

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

请查看内联评论

Answer 1

您需要序列化数据。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Marshal.load（）。

将json存储在数据库中，稍后再解析它
