Hello
I have a strange problem with this code:
<%unless (@students.empty? and params[:commit].nil?) %>
<%="test"%>
<%= render :partial => 'results' %>
<% end %>
Even though in some cases @students.empty? returns false and params
[:commit].nil? returns true (or the opposite), it displays the test
and the render area.
I put before and after the code the <%=params[:commit].nil?%> and <
%...@students.empty?%> so I can see it (it shows false and true or the
opposite and always it shows the render area and the test). I also
tried && but it was the same problem.
The only way it worked was this:
<% unless @students.empty? %>
<% unless params[:commit].nil?%>
<%="test"%>
<%= render :partial => 'results' %>
<% end %>
<% end %>
So why "and" - "&&" doesn't work? I tried every combination with () or
without ()...
Thank you
