javascript - Submit Rails from on change of selected value in dropdown form -


i have rails app listing of leads in table. in 1 of collumns display status of lead in drop down menu. want enable changing status of lead on changing value selected in drop down.

this tried:

the code display form in table cell:

      <% @leads.each |lead| %>   <tr>     <td><%= lead.id %></td> <td><%= form_for(lead,:url => 'update_lead_status') |f| %>               <div class="field">                 <%= f.select :status, ["to_call","called","confirmed","lite"], :selected => lead.status, onchange: "this.form.submit();" %>               </div>             <% end %>         </td>

my update_lead_status method in leads controller:

#put   def update_lead_status     @lead = lead.find(params[:id])     respond_to |format|       # format.js       if @lead.update_attributes(params[:lead])         format.html { redirect_to leads_url, notice: 'lead updated.' }         format.json { head :no_content }       else         format.html { render action: "edit" }         format.json { render json: @lead.errors, status: :unprocessable_entity }       end     end   end

also want submission ajax style without refreshing.

set form id , submit form

<%= form_for(lead,:url => 'update_lead_status',:html=>{:id=>'lead_form'}) |f| %>   <%= f.select :status, ["to_call","called","confirmed","lite"], :selected => lead.status, onchange: "$('#lead_form').submit();" %> <% end %>

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!
