I´m not sure that you can use the collection_select with a link, better use
a form
try something like:
VIEW
<%= form_tag( :controller =>"Catvalues", :action => "detroy", method =>
"delete" do %>
<%= collection_select(:catvalue, :id, @catvalues, :id, :v_name, {}, class:
'drop-down')%>
<%= submit_tag("Destroy")
<% end %>
´CONTROLLER
def destroy
@catvalue_del = Catvalue.find(catvalues_params[:id])
@catvalue_del.destroy
redirect_to catvalues_path
end
def catvalues_params
params[:catvalues].permit(:id)
end
