That is some ugleeeeee code. The rails way is to avoid instance variables like the plague and instead reference ActiveRecord objects.

you can put your layout in a partial – keeping the view out of the controller.

Using the inline form above, you’d call:

render( :text => @html )

Instead, you can call:

render( :partial => ‘partial_name’, :layout => false ).

The layout file lives in the same dir as the other views for this controller and must be named

_partial_name.js.erb

my view:

“type_id”,
:with => “id”, :url => { :controller => “event”,
:action => “category_changed” } %>

Hi, i’m having problem trying to use observe_field: my view is like this

“type_id”,
:with => “id”, :url => { :controller => “event”,
:action => “category_changed” } %>

in the controller i’m updating @types(with query to DB),but is this enough,or i’m missing something?type drop-down is always empty!I don’t want any html inside my controller

Tnx.

Hi thanks for the advice on this article. There just one thing I get this error when using your code:

syntax error, unexpected tIDENTIFIER, expecting kDO or ‘{‘ or ‘(‘

For this line:

@html = â€œâ€

Other than the id and name changes theres no difference. Do you understand what the problem is? Many thanks. Lyn

class AdminController :city_name,
:clear => ['area_id']})
end
end
def city_update
return unless request.xhr?
areas = State.find( :all, :conditions => ["city_id=?", params[:ecosite_index]])
flash[:notice]=”#{params[:ecosite_index]}”
render :update do |page|
page :area_name} )
end
end

def index
@states=State.find_by_sql(“select distinct name,state_id from states”)

end
end

can anyone get the code for dynamic drop down lists to put that on view page using rubyonrails…
like one drop down list consists list of states and other drop down list should contain list of states… and on selection of state from the first drop down list, the options in the second drop down list should change….
if any one can code for this i vll b thankful….
