Question

I used mongodb as my database and the driver mongoid.

One of my model Bill has a field is local_time, and I used datetime_select in the view:

.ym-fbox-select                    
  = f.label :local_time, "Time"
  = f.datetime_select :local_time 

the create action is OK. But the update action is not.
The error is like this:

(eval):1: syntax error, unexpected tINTEGER, expecting ')'
    def local_time(1i)=(value)

and the update is :

def update                                   
 @bill = Bill.find(params[:id])             

 respond_to do |format|                     
   if @bill.update_attributes(params[:bill])

So I want to know how to update the local_time field?

Add include Mongoid::MultiParameterAttributes to your model, just as you would for Timestamps.
