I was trying to create a radio button in scaffold form but got error
here is the form codes-
<%= form_for(@value) do |f| %>
<% if @value.errors.any? %>
<%= pluralize(@value.errors.count, “error”) %> prohibited
this value from being saved:
<ul>
<% @value.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<%= f.label :fname %>
<%= f.text_field :fname %>
<%= f.label :lname %>
<%= form.radio_button :lname, 'yes I have' %>
<%= form.label :red %>
<%= form.radio_button :lname, 'No I don't' %>
<%= form.label :yellow %>
<%= f.submit %>
<% end %>
but when I clicked on new button. It's giving me this error-

Surely you can see the error here, you have single quote character in
the middle of a string using single quote to identify it. Ruby will
see the string as ‘No I don’ and is then confused by the t character.
Use “No I don’t” instead.

Thanks…I fixed it . But now it’s giving me this error-

Once again the error is not difficult to see if you look carefully.
The error says undefined method radio_button for something that is nil
and tells you the line. Look at the line, what variable are you
calling radio_button on? What is the value of that variable?

issue and tried to type lots of stuffs…my mistake was mainly cotton

It is always worth looking at the error carefully and trying to work
out what it means. That is not always obvious but will get easier
with practice.
