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
