I've got a helper method to add classes in my view, last argument is optional. Right now I'm testing for the optional argument with "if (defined?(project.first)).nil?", but it's not working as expectedů*it's always returning false, even when I KNOW there is a hash getting passed to it.

Also, another thing is my record that I submit as the optional argument is getting turned into an Array. If I remove the .nil? test then it works when the optional argument is present but fails when not present.

Anyone see something I'm doing wrong?

PHP Code:
@project Project.find(params[:id]) 
PHP Code:
<%= calendar_classes(day, @project) %> 
PHP Code:
  def calendar_classes(day, *project)
    
class_string = []
        
    if 
day.wday == 
      class_string 
<< "week_start"
    
end
    
    
if day.wday == 6
      class_string 
<< "week_end"
    
end
    
    
if day.to_s.eqlDateTime.now.strftime('%Y-%m-%d')
      
class_string << "current_date"
    
end
        
    
if (defined?(project.first)).nil?
      if 
day.to_s == project.first.start_date.to_s
        class_string 
<< "project_start"
      
end
    
      
if day.to_s == project.first.due_date.to_s
        class_string 
<< "project_end"
      
end
    end
    
    
return class_string.join(" ")
  
end
