  Hi Mike…
  Thanks for the great tutorial. I’ve been struggling with AS; the documentation is quite minimal. One thing your article didn’t discuss was how to add a custom nested link. I want a link with each row that will simply display a partial and not have to call a completely different controller.

  Is this somehow possible? I can’t figure out how.

  You could try adding a column to the list:

  config.list.columns.add :fake

  and then add a helper for that column in your helper:

  def fake_column(record)
  “this is a fake column”
  end

  This is a pretty bad hack though. You might ask on the AS mailing list and see if anyone has a better suggestion.

  Hello Mike,
  thanks a lot for this article which helped me especially on the localization subject. For others who may fiddle like I did with their .po files of gettext until they figured out the missing line, I’d like to send a snippet of application.rb’s tail:

  class Object

  include GetText
  bindtextdomain(”domain”) # THIS ONE!

  def as_(*args)
  _(*args)
  end
  end

  Cheers [ofi]

  dear mike,
  thank you for the nice tutorial, it is really filling a gap.
  my little experience gives me a problem with your suggestion for the to_label method: i get a
  uninitialized constant Person::NAME

  when i use NAME (a column in the table) as the label.
  could you tell me what i am failing to do?
  thank you!!

  Sergio, this isn’t really the appropriate place to help with typical Ruby problems. You might post your source on the ActiveScaffold mailing list and see if someone can help you there.

  I also found your article very helpful. The part I am trying to figure out is how migrations work in AS.

  I created a table with a migration and then used ActiveScaffold to have it quickly show up on my page. I then added another table and an extra field to the first table (foreign key - “user_id”) into the next iteration of my migration. After doing this the new information does not show up in the AS Page with the new field (”user_id”) column. Is it hidden by default? Is there a way to force it’s visibility? How can I get the subforms to show up so I could change the user in the original table?

  Thank you for your insight,
  Grant

  Grant, have you added an association in the model, e.g. “belongs_to :user”?

  the model listing on the article seems incomplete. many relationships are not defined. The source code has the right version

• 9 mperham // Oct 6, 2007 at 5:20 pm

  mcr, the code listing in the text is not meant to be canonical, just illustrate the topics described in the text.

  i’m using AS for my project - where i’m finding it difficult to do the following
  1. in query screen how do I add drop down values pulled from DB?
  2. how to add image file upload in create/update screen using AS

  Dear Mike,

  Great article!

  Is there any way to have multiple models scaffolded in the same controller?

  Best regards, RIcardo

• 12 mperham // Nov 13, 2007 at 5:34 pm

  @Ricardo, the only thing I know of like that are embedded scaffolds:

  ActiveScaffold is a greate rails plugin.
  But i have some trouble when i use it.
  I looked for the ways to upload file or image but fail to do it. Any ways?

  Thanks for the tutorial. I’m trying to understand action links, and I have a few questions from your article. I am brand new to RoR, so please bear with me…

  1) In your csv_header method, should the header line be encased in single quotation marks instead of double quotation marks? Alternatively, should the quotation marks surrounding the ID field be escaped? (I got syntax errors otherwise, in my RoR 2.0.2 installation.)

  2) On Rails 2.0.2, should there be some routing magic performed in order to get to the export_csv method? Following your example, I got:

  ActiveRecord::RecordNotFound in DocumentsController#show
  Couldn’t find Document with ID=export_csv

  From what I’ve read about the routing mechanism, and RESTful rails, I can see why I’m getting this error. I’m just not sure what the “best” method is to work around it. So I added the following to config/routes.rb:

  map.connect ‘documents/export_csv’, :controller => ‘documents’, :action => ‘export_csv’

  Note that I had to add it _before_ my “map.resources” line, so that it would match first. It feels like I’m typing the same 2 things a lot (”documents” and “export_csv”), so I wonder if I’m not being as DRY as I could be.

  Is there a simpler way to connect the link to an action in my controller? I tried specifying :controller and :action in the conf.action_links.add line, but that didn’t help.

  3) This aims me in the direction that I want to go, which is that I would like to have a drop down menu to narrow the view of my table down based on specific categories of records in my table. Can you give me any pointers on how I might do that? I would like the user to select a category from the drop down menu and filter the results displayed based on the category. Ideally, I would like the display to update immediately, which I think means AJAX, but, as I said, I’m still learning.

  Again, thank you for the time and effort you put into your tutorial. I hope my documentation of my attempt try the action links part on RoR 2.0.2 will help more than it will hinder somebody else going down this road.

  1) Yes, good catch.
  2) The article was written pre-REST. Routing in Rails 2.0 is very much biased towards RESTful routing so this code won’t work very well on 2.0. Since CSV is just a format, we really should be using responds_to with a file extension on the URL to “route” to the CSV formatter, like “/documents/123.csv”.
  3) Sorry I can’t help you here. I haven’t used AS since the article was published so I’ve lost most of my AS mojo! I’m sure the mailing list can help here.
