I have a form. Everything submits into the database if I don't have any validation rules. When I put these rules: validates_uniqueness_of :title, :message => "already exists in database" validates_presence_of :title I get this error (which seems weird because I am not validating against that): You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occured while evaluating nil.each Extracted source (around line #18): 15: <p><label for="resource_focus_id">Focus</label><br/> 16: <select name="resource[focus_id]" id="resource_focus_id"> 17: <option value="" selected="selected"></option> 18: <% for @focus in @focuses %> 19: <option value="<%= @focus.id %>"><%= @focus.name %></option> 20: <% end %> 21: </select> Seth B.

Its because you are redisplaying your form with out reloading the options for your form. The render method does just that, it simply renders the view, it doesn't call any other methods in your controller. Try adding this before you render the form again: @focuses = Focus.find :all
