Hi,
I have some issues with setting the selected value. On my page, user
selects a State from the drop down and other attributes and click on
"Find". I want to set the default value of the drop down to the value
selected prior to clicking "Find".
<%=collection_select(:state, :state_id, @states, :state_id, :state_name,
{:prompt => true, :selected => @selected_state},
{:style => 'width:200px;',
:onchange => remote_function(:url =>
{:action => 'update_cities'},:with =>
"'state_id='+value")})%>
In my controller, if I have @selected_state = 1, the dropdown default
value is shown in the UI. However, if I have @selected_state =
state_id, the default value is not set.
Snippet of the code in my controller:
def find
state_id = params[:state][:state_id]
@selected_state = state_id
/* Some logic here */
@states = State.find(:all)
respond_to do |format|
format.html { render :action => "index" }
end
end
Any pointers are appreciated. Thanks.
