Hi,  
Am creating a survey, in which am getting the questions from question  
table and answers from answers table.  
In the survey table am displaying the questions with the answers as  
multiple choice using radio buttons.  
Also while selcting the option the vote\_count should be increased.

The front end part is working correctly, it shows as per my requirement.  
but no values are updated in the database.

\<%=radio\_button(:nominees, count, :onclick =\>  
@voting.increment!(‘vote\_count’) ) %\> \<%= response.nomination %\>  
i want to store the selected values in nominees attribute and want to  
increase the vote\_count by selecting the option.  
any help or advice reg this would be very helpful.

Keep a default value in the answer table for this particular field  
instead of keeping it NULL

the onclick option needs to be a fragment of javascript. Right now you  
are calling @voting.increment! at the point that the template is  
rendered.

Thanks for the quick reply,  
Am getting the radio button options from answers table. also its a group  
of radio buttons.  
so the count means for the radio\_button id. if i change the count as  
follows

\<%=radio\_button(:survey, :nominees, count, :onclick =\>  
@voting.increment!(‘vote\_count’) ) %\> \<%= response.nomination %\>

i cant select the option for each question. i can only select one  
option for the whole survey.
