Updating attribute based on radio selection

Rails
1

I have a table with question_id , nominees and vote_count in which the
values are added manually as follows.
ex:

question_id nominees vote_count
1 tamil 0
1 selvi 0
2 aaaa 0
3 qqqq 0
3 wwww 0

using this i have created a surevy.

when i select a nominee, then the vote count for the particular nominee
should be updated like this.
question_id nominees vote_count
1 tamil 1
1 selvi 0
2 aaaa 1
3 qqqq 0
3 wwww 1

am implementing this as follow,
<% count = 1 %>
<% for voting in @voting %>
<% if voting.question_id.eql?(count) %>
<%= radio_button( count, voting.vote_count, :id => voting.nominees ) %>
<%= voting.nominees %>

<% voting.update_attribute(‘vote_count’, voting.vote_count+1 ) %>
<% end %>

but it updates vote_count for all the nominees like

question_id nominees vote_count
1 tamil 1
1 selvi 1
2 aaaa 1
3 qqqq 1
3 wwww 1

how can i compare the selected nominees with the existing one.

any help on this would be very useful…

Why are you doing model updating in the view? Can you post the
corresponding controller code?

You use a loop to read every record in your table, and inside that
loop, the line:

voting.update_attribute(‘vote_count’, voting.vote_count+1 )

updates every record adding one to the previous value. Your “if
voting.question…” encloses only the line below it (It appears that
<% end %> is missing.

sorry,i have missed to paste the <%end%> in the post.

actually i need to compare the selected nominee with the available
nominees .
if both are equal then i need to update the vote_count. so only i
updated the model in view…
