The documentation states as an example:
select("post", "person_id", Person.find_all.collect {|p| [
p.name, p.id ] },
{ :include_blank => true }) could become:
<select name="post[person_id]">
<option></option>
<option value="1"
selected="selected">David</option>
<option value="2">Sam</option>
<option value="3">Tobias</option>
</select>
I have the following code in a _form.rhtml file:
<%= select("category", "prnt_id", Prnt.find_all.collect
{|p| [p.name, p.id]},
{ :selected => ''prnt_id'' == @category.prnt_id,
:include_blank => false } ) %>
The drop down is created with the correct content, but is does NOT select the
currently set value. The value is set if I use any other type of input (ie
text_field).
Is there an error in the doc? If so, does anybody know how
''selected'' is set?
TIA

I use this all over the palce and that is the only difference I see between yours and mine. Rails will call @ category.prnt_id for you in the select helper. Also just as an FYI, :include_blank => false is the default setting. <%= select("category", "prnt_id", Prnt.find_all.collect {|p| [p.name, p.id]} ) %> -- Mark Van Holstyn mvette13@gmail.com http://lotswholetime.com -------------- next part -------------- An HTML attachment was scrubbed...

Specify :selected => value to use a different selection or :selected => nil to leave all options unselected. Instead of :selected => value, you''ve got :selected => ''prnt_id'' == @category.prnt_id You should probably try this: { :selected => @category.prnt_id, :include_blank => false } Dan -- Posted via http://www.ruby-forum.com/.

All do not seem to generate a selected= in the html code. I''m using Rails 1.1. How about you? g
I am also using rails 1.1. Check to make sure that @category.prnt_id is returning what you expect it should be returning. It may be returning nil, or a value which doesnt exist in the options for the select. mark -- Mark Van Holstyn mvette13@gmail.com http://lotswholetime.com -------------- next part -------------- An HTML attachment was scrubbed...

I cannot get it to select an option by default (or by specifying value to select). Here''s my code: <%= select("thing", "category_id", Category.find_all.collect { |c| [c.name, c.id] }) %> Yes, @thing.category_id is what I''m expecting and it is a value in the options.

It looks like @thing.category_id is being treated as a String while c.id is being treated as a Fixnum.
