This is my code (elipsis is to make line shorter): ``` '-- Select One --', :required => true %> ``` Which outputs ``` Category: -- Select One -- Analytics Commerce Content Management Gaming Green Media Social Media Technology - Software Technology - Hardware Web </div…

Problem

I am trying to have a `<select>` be required in my Rails form. This is my code (elipsis is to make line shorter): ``` <div class="field"> <p><%= f.label :category, "Category:" %></p> <%= f.select :category, ['Analytics','Commerce',..., 'Web'], :prompt => '-- Select One --', :required => true %> </div> ``` Which outputs ``` <div class="field"> <p><label for="startup_category">Category:</label></p> <select id="startup_category" name="startup[category]"> <option value="">-- Select One --</option> <option value="Analytics">Analytics</option> <option value="Commerce">Commerce</option> <option value="Content Management">Content Management</option> <option value="Gaming">Gaming</option> <option value="Green">Green</option> <option value="Media">Media</option> <option value="Social Media">Social Media</option> <option value="Technology - Software">Technology - Software</option> <option value="Technology - Hardware">Technology - Hardware</option> <option value="Web">Web</option></select> </div> ``` Putting `{:required => true}` instead of `:required => true` gives a syntax error and `{:prompt => '-- Select One --', :required => true}` renders the page, but without the `required="true"` in my select tag. How can I get `required="true"` in my tag?
