Just update 1 field
Hi All,
I wonder how I can get rails to update just one field when I do Myfile.save.
Right now this happens when I do a Myfile.save:
UPDATE myfiles SET `folder_id` = 0, `filesize` = 1, `data` =
''2f7573722f6c6f63616c2f6d ... f7061636b65743d33324d'', `user_id` = 0,
`date_modified` = ''2006-01-11T23:33:57+0100'', `filename` =
''mysqlscripts.sql''

Relating to records in same table
I''m in progress of making a little folder system with Ruby on Rails.
I''ve got a "folders" table. Each "folder" has got an id and a folder_id.
The folder_id is supposed to represent the folders'' parent folder.
How can I tell Rails?
I would like Rails to automaticly delete all subfolders of a folder when
I delete the folder it self.
Any ideas?

Check if a saved user''s name is admin
Hi all,
I have a question about this method in my User model:
# Returns true for the (saved) user called "admin"
def is_the_administrator
true if save and name == "admin"
end
The method returns true if the user''s name is admin. However, I only want to
return true if the state of the object is "saved", so I call the save method
first.

Temporary files / Uploads
Hi,
how can I influence, where mongrel stores temporary files like uploads.
As far as I can see, int honours the TMP or TEMP environment. Can I also
set it in the configuration file for mongrel? I have not found something
about it in the docs.
Another thing:
When I upload a file, the file is stored 3-4 times:
In the TMP by mongrel as
mongrel.3400.0 and then as
CGI.3400.0

Call a script after every file modification
Is there a simple possibility to hook in a script which is called every
time a file is modified via smbd, e.g. a user is adding a file via samba
share? The script should get also the filename too :-)
The intended purpose is to duplicate the write operations of samba to
another disk. Yes I know there exists RAID and Rsync and other software,
but I want to use it for longtime archiving purposes,

Split number of imap-login and pop3-login processes
Hi All,
Is there a way to define the number for imap-login processes and pop3-login processes separately?
My mail server is getting more IMAP clients and much less POP3 clients these days and it continues to run out of authentication processes.
I have been increasing login_max_processes_count the last couple of days and I noticed that it's split between IMAP and POP3.

Which method to use to get content from index with a_a_f?

After staring at the a_a_f API for quite sometime now, I decided it''s
time to ask...
Which method should I use to get content from the index without using
highlight? Consider the following controller action:
def preview
if params[:search].blank? # normal case
@text = @myfile. # which method do I use here to get the :text from
the index???

ApplicationController common view
I created a user login system in ApplicationController. There is a def
called signin. It needs a view file, signin.rhtml
I have a couple of other controllers inheriting from
ApplicationController. Where can I place the view file so it is
viewable across all controllers? I tried the root view folder but that
didn''t work.
Right now, I would have to copy and paste the signin.rhtml file

Design Decisions
Hi All,
I am doing some research on how people start with their Rails app.
What design decisions are made and how is it build.
For example:
- do you use scaffolding and go from there? Or do you create everything
from scratch?
- are you using multiple controllers? Or do you put everything in one?
- do you use migrate?
- how do you use migrate? Do you call migrate your self or do you use

Using Dovecot-auth to return error code 450 (or other 4xx) to Postfix when user is on vacation
Hello to all members.
I am using Dovecot for 5 years, but this is my first post here.
I am aware of the various autoresponder scripts for vacation autoreplies (I am using Virtual Vacation 3.1 by Mischa Peters).
I have an issue with auto-replies - it is vulnerable to spamming with forged email address.
Forging can be prevented with several Postfix settings, which I did in the past - but was forced

Read data from Excel
A client of mine has a ton of data stored in Excel spreadsheets. I''m
building a web application for her (backed by a real db of course) and want
to import all that data. Is there a library available to read data from
Excel? Is there an easy way to upload the spreadsheets and then read the
data?
Thanks,
