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.

This should help, provided that you have a name attribute in your Project model:

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

You can find more on select boxes in form builders here guides.rubyonrails.org/…. Can you accept the answer if it solved your problem?

I noticed that it would now show the name of the project, but when I submitted, it displayed as the id of that project name. I changed the code you suggested to <%= f.select(:project_name, Project.all.map {|p| [p.project_name]}, :prompt => "Select a Project") %> Which now works perfectly, Thank you.

This really depends on what exactly you want to be submitted from the select box. Submitting names from a single selection box is OK when the names are unique, but generally you'd want to use unique attributes such as IDs.
