ruby on rails - Getting correct index in nested form's fields_for -


i using ryan bates' nested form in rails 3.2.13 , having issue getting correct indexes when trying embed javascript.

i able index dynamically generated content using: 

=f.fields_for :entity, :wrapper => false |e|   =e.input :name   %div{ :id => "entity_#{e.options[:child_index]}" }   :javascript     $("entity_#{e.options[:child_index]}").foo()

however, when editting same form existing data index blank rows have data.

it looks e.options[:nested_child_index] should contain correct value private variable exception when attempting access it.

how should correct index can pass along?

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!
