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

<%= radio_button yourmodel, model-attribute, value, :onclick=>something %>

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 %>

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.
