file_column in session
is it possible to store a field of type file_column in the session?
Rails crashes on me every time i try to do something like the
following:
@session[:newpost] = @params[:post]
however if i assign each field of @params[:post[ except for
@params[:post]["image"] i have no problems. Is there something that
should be done to allow the file in the session?

problem with nested loops
Each of the data sets contains monthly observations on price indices for 7 countries. I use the fitted values from reg1 in the reg2 model. The interior loop executes without error as long as I explicitly specify the data set, i.e. data=dat70. However the code fails to execute if I specify the model in the form of the commented line, i. e reg1 <-dynlm(form1,data=Dnames[j])

indexing in a function doesn't work?
Hello,
I've written a small function that's supposed to save me some time, and
it's ending up killing it- the intention is to iteratively subset a dataset
fram on framevec, fit a model (either lm or nls depending on type) and
return the r2 or AIC from the model, respectively. Although as far as I can
tell in my code the plots are dependent on the fit of the model to the data
and the

Scaffolding to use has_many and belongs_to ?
What does everyone on this list think about enhancing scaffolding
somehow so that a "has_many" relationship will automatically drop the
<select> box into the view to reference the "belongs_to" part of the
view?
I think scaffolding is great but I am always adding the <select> boxes
to reference the parent association. Do you think this would be
useful? just a

File_column not keeping value during page reloads
I''m trying to use the file_column plug-in to attach a file to a
newsletter posting. It works fine if I get the form right the first
time, but if I get an error, such as not typing in a required field, and
the form re-displays, my file selection box reverts to "no file selected."
Here''s my relevant controller code:

ajax in rails is a security violation
Does anybody have any issues with the AJAX code inside rails? Whenever i

internal security device blocks access to the Ajax piece with a 400 Bad
Request ( i scoured the net for other ajax examples and no isses anywhere
else). I think there is something in the AJAX code of rails that is not

Rails Best Practices Page
Hey,
I have been progressively learning more and more rails each day
(from both a current project, reading the agile book, and this list).
Does anybody think it would be beneficial to have kind of like a rails
"Best Practices" page that lists some of the better ways of handling
certain functions of rails (that are common in most apps) that are
both more elegant, and efficient.

Showcase On Rails CMS v0.1
I built out a simple CMS for websites that rely heavily on portfolios.
This covers graphic and web designers in particular, but also other
people with stuff to show off. It''s really easy to customize
progressively, so that some people will only modify CSS, but others
will dig deeper into Javascript behaviors and the Rails view code.

Jabber Powered Rails Chatroom
For those who cant access IRC, or just looking for a quick browser based
alternative, i started an open jabber powered webchat for rails. Hopefully
this will be a nice alternative for people to go to ask questions, get some
help, offer some help, etc.
I hope the community enjoys it, just trying to give a little back for all
the hard work.

How might I use file_column for incoming email attachments?
I''m writing a ''Mailman'' model that catches emails sent to my
application (kind of like backpack, I think). The trouble is that
I''d like to save image attachments in the same was that file_column
saves them--in fact, I''d really like to use a simple assignment like
photo.image = attachment to save the image in its proper place.
However,
