Many posts I found about this, and many possible solutions, but i just
can''t get this simple thing to work: i tried every single solution i
found:
<%=select_tag
"location",options_from_collection_for_select(Location.find(:all),
:id,
:name, "2")%>
<%=select_tag
"location",options_from_collection_for_select(Location.find(:all),
:id,
:name, 2)%>
<%=select_tag
"location",options_from_collection_for_select(Location.find(:all),
:id,
:name, {:selected=>"2"})%>
<%=select_tag
"location",options_from_collection_for_select(Location.find(:all),
:id,
:name, {:selected=>2})%>
<%=select_tag
"location",options_from_collection_for_select(Location.find(:all),
:id,
:name, {:selected_value=>"2"})%>
is there anybody out there who knows how to do this?

Hi Remco Is that a typo and there is a spcae between <%= and select_tag in your code?

I add an additional advice. Remco you should remember that RoR is designed with MVC. I disagree if you put Location.find(:all) in your view. Put it in your controller as instance variable, then put your instance variable into your view. Controller: @locations = Location.find(:all) View : <%= select_tag "location",options_from_collection_for_select(@locations, :id, :name, "2") %> Feel the taste of ROR by Optimizing MVC. Good luck.

I am aware of that, but i am afraid that doesn''t solve my problem. Visit Indonesia 2008 wrote:> I add an additional advice. Remco you should remember that RoR is > designed with MVC.

I think you will need to put the select_tag in parentheses like this. <%= select_tag( "location", options_from_collection_for_select(Location.find(:all), 2)) %> On Apr 28, 5:33 am, Remco Hh <rails-mailing-l...-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org> wrote:> Many posts I found about this, and many possible solutions, but i just > can''t get this simple thing to work: i tried every single solution i > found: > > <%=select_tag > "location",options_from_collection_for_select(Location.find(:all), :id, > :name, "2")%> > > <%=select_tag > "location",options_from_collection_for_select(Location.find(:all), :id, > :name, 2)%> > > <%=select_tag > "location",options_from_collection_for_select(Location.find(:all), :id, > :name, {:selected=>"2"})%> > > <%=select_tag > "location",options_from_collection_for_select(Location.find(:all), :id, > :name, {:selected=>2})%> > > <%=select_tag > "location",options_from_collection_for_select(Location.find(:all), :id, > :name, {:selected_value=>"2"})%> > > is there anybody out there who knows how to do this? > -- > Posted viahttp://www.ruby-forum.com/.--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Sorry no I didn''t run it but the source of the error is easily fixed.
