Rails Console Inserting Data into a Record -


this did 

customer.all    customer load (0.6ms)  select "customers".* "customers"  => #<activerecord::relation [#<customer id: 1, name: "judy ngai", created_at: "2013-08-13 18:50:02", updated_at: "2013-08-13 18:50:02", phone_number: nil>]>

then 

judy = customer.find(1)  insertdata = judy.phone_number = "1234567890" insertdata.save! or  insertdata.save

gives me 

nomethoderror: undefined method `save' "6265607524":string nomethoderror: undefined method `save!' "6265607524":string

what should do? 

judy = customer.find(1)  judy.phone_number = "1234567890" judy.save!

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
