Stop array of strings from saving with dashes

I'm listing the models in my app so an admin can create custom roles:

        <% ActiveRecord::Base.send(:subclasses).each do |model| %>
    <tr>
        <td width=10>
            <label><%= check_box_tag "role[read_models][]", model.name, @role.read_models.include?(model.name) %></label><br />
        </td>
        <td width=10>
            <label><%= check_box_tag "rol开发者_JS百科e[write_models][]", model.name, @role.write_models.include?(model.name) %></label><br />
        </td>
        <td><%= model.name %></td>
    </tr>
    <% end -%>

It works great by the way. In the log it saves the array properly like so:

"read_models"=>["Slug", "Account", "Category", "Document", "Group", "Location", "Role", "Status", "Task", "Ticket"]

But when outputting the results:

<%= @role.read_models.each do |model| %>
   <%= model %><br />
<% end -%>

I get this:

--- 
- Slug
- Account
- Category
- Document
- Group
- Location
- Role
- Status
- Task
- Ticket

(Including the three dashes in the front)

I've tried doing to_a.join(', ') but it still has the dashes in front of each one.

Any ideas on how I need to change this process? Thanks!

I am guessing you have a Role class and this class is the one used to store these values, if this is your case, here's what you could do:

class Role < ActiveRecord::Base
  serialize :read_models, Array
end

This will make ActiveRecord store these values you have at the read_models column as a YAML representation (this one you already have) but then you make @role.read_models you will get the Array back and not a string containing the YAML representation.
