I have a database with phonenumbers, and I want to make a function
that runs a command for each of these numbers, with the number as an

limiting options in file_upload
Does anyone know if it''s possible to set constraints to the size & type of file that file_column will accept?
I''d like to limit to image files of less than 2MB.
If this isn''t possible with file_column, is there a graceful way of getting the controller to handle it?
thanks

Saving images in shared directory w/ Capistrano/SVN?
Hi all,
I''m using Capistrano and SVN to version control and deploy, but I''m not
sure what to do about my images directory. I use file_column and
RMagick to save images to the disk under a model called "Image", and
they''re saved in public/image/... etc.
Each time I deploy a new version, my image folder doesn''t exist anymore.

Problems with validates_presence_of...anybody?
Hello everybody,
I have been developing small applications in Rails from quite some time.
But lately, I came across a bug which I have not been able to correct.
If anybody could help me with it, would be of great help thankyou.
Actually, the problem is that I have a form in my application with some
set of fields.
Now what "validates_presence_of" should do is that if I submit the form

validates_presence_of
I am just going through the book and I come across a problem with the
code in the app/models:
validates_format_of :image_url,
:with => %r{^http:.+\.(gif|jpg|png)$}i,
:message => "must be a URL for a GIF, JPG, or PNG image"
It seems to moan when it''s empty even though I removed :image_url from
validates_presence_of. How should I make it optional?

Subversion and Capistrano
I have a project under Subversion, deployed by Capistrano.
When it is deployed, obviously I need to deploy "real" copies of
database.yml, deploy.rb, and maybe a couple of other files.
But if I offer it for public checkout, I obviously do not want these
files as part of the checked out code.
What''s the best way to handle this?

Clearing a file_column-type field
So I am now able to set/upload an image to my app using file_column,
with a little bit of a change to the code.
I can change the image using an Edit page, but I''m trying to figure out
what to do if the user wants to remove the image. I tried adding a
Remove Image link in my list, but I''m not sure what to do in the

Hi all -
I''d like to implement a lookup table in my app that contains some
reference data, just some status codes and their descriptions. What''s
the most appropriate approach according to the "rails way" of doing
things? Would I just implement a has_many relationship? Let''s say
these are Order status codes, would the StatusCode have many Orders?

Unicode HOWTO?
I am disappointed about the (seeming) lack of Unicode support in Rails.
Is there a howto about working the most important limitations? For
example, figuring out the length of an entered word: "???".length() will
return 6, not 3. So if there is a maximum number of characters a user is
allowed to enter, this won''t work as it should -- it treats strings as
byte arrays instead
