Rails Admin modify list/show view to add new/customized column

I have setup the rails_admin for the admin interface of my site.

For one of the Model, I want to display an additional column.

say i have name , phone , email, image url, rank etc attributes in my Model(say Student). Then I have to display columns : Name | Rank | Preview(additional column)

In the preview column i want to display some rendered html on the basis of attributes ( email,image,url etc.) for each 'student'.

I have found the way to include a partial for edit/update/create to provide fields/forms as per our partial. But the same implementation of including partial is failing in list/show.

So is there any way I can add the partial to show rendered content, in list/show view for a model...?

Edit: Code added

config.model Utility do
   list do
     field :code
     field :priority
     field :name
     field :url
     field :phone
     field :logo
     field :content
     sort_by :priority
     items_per_page 100
   end
end

This shows up following columns in rails_admin

Code | Priority | Name | Url | Phone | Logo | Content

what i want is Code | Priority | Preview

in which in Preview column i want to show a html rendering content as :

blah.html (just for e.g. html for example , here i want to render in a way it is displayed in one of pages, so it is presentable for admin view too)

<div class="blah">
  <%=util.name%> <%=util.phone%> <%=util.logo%> #usage with proper divs/tags/rendering
</div >

Rails Admin calls these "virtual" field types. The easiest way is to make a method on your model, and then refer to it it in your list / show:

class ModelName < ActiveRecord::Base

  def invite_link
    %{<a href="http://site.com/#{self.uid}">invite link</a>}.html_safe
  end

  rails_admin do
    configure :invite_link do
        visible false # so it's not on new/edit 
    end

    list do
      field :name
      field :invite_link
    end

    show do
      field :name
      field :invite_link
    end
  end
end

        </div >}
    end
    children_fields [:name, :phone, :logo] # will be used for searching/filtering, first field will be used for sorting
    read_only true # won't be editable in forms (alternatively, hide it in edit section)
  end



  list do
    field :code
    field :priority
    field :preview
  end

  show do
    field :code
    field :priority
    field :preview
  end

  # other sections will show all fields
end

Abstract:

Show/list don't use partials for output. Last overriding point is pretty_value.
