Rails 4 - Using Transactions along with Begin rescue block

i have a piece of code which is used to do following things triggered from a controller call.i am using Rails Transaction along with begin/rescue end block to make the below series of code execution more robust.Its as shown below:-

1. Save the object
2. save the associations and update the attribute value
3. send email
4. send text message

5. redirect

   ###in my controller 
    def verify   
       @request=Request.includes(:user).find(params[:id])
       @request.transaction do
         begin
           if @request.accepted?
              ##this method will call more 3 methods in the request model
              @request.send_email_and_sms
              flash[:success] = "Request is moved to another state"
           else
             flash[:error] = "Request was not accepted and couldn't be moved to another state"
           end        
         rescue
           flash[:alert] = "There was some internal error.Kindly debug"
         ensure
           @request.reload
           Rails.logger.info "================Making GO AHEAD TOKEN FALSE AND DEACTIVATE VENUE====================#{@request.attributes}==========="
           redirect_to request_hall_path(@request.user)
         end      
       end    
     end
   
   

   `

Is this the correct way to ensure that every piece of code will execute else it will jump on rescue with the flash.alert message.

Is there any other way that i am missing to make this code/logic more full proof and robust.

Thanks in advance.
