Ruby on Rails - Drop down menu

Question

A noob here. I've only just started to learn ROR, and I'm having a problem with a drop down menu, that allows the user to select a project from a database. I have the drop down menu working, however instead of the project names, it shows something like Project:0xb61fbdbc.

    <%= f.label :project_name %><br />
    <%= f.select(:project_name, Project.all, :prompt => "Select a Project") %>

I have searched,and searched and had no luck. Hopefully someone can help.

Thanks in advance.

只要您在Project模型中具有name属性，这应该会有所帮助：

<%= f.select(:project_name, Project.all.map {|p| [p.name,p.id]}, :prompt => "Select a Project") %>
