similar to: What's the maximum storage size of a Session ?

I''m seeing a "marshal data too short" error with an ActiveRecord store for my session data. Other posts say that this happens when the size of the session data exceeds the size of the "data" column in the sessions table.

I have an item which has a hash for one of its fields. When i store it in the db, i want to do a Marshal.dump of the hash, and similarly, do a Marshal.load to turn the saved blob back into a hash again. Is there a way to easily write this into the model, so that it happens automatically when saving and loading a record? thanks max -- Posted via http://www.ruby-forum.com/.

hello. i just checked Chad Fowler''s post "20 Rails Development No-No''s" and one guideline caught my attention. it says: "Nothing that looks at all like SQL should go into a controller, view, or helper." it really came as a surprise to me as Rails itself seems to go against such practice by its AR ''conditions'' option, which most of the times

This might seem really simple to some but just wanted to ask: what is the difference between @session[''user''] and session[:user] ? and how would you use each?

Railsters: ActiveRecord''s validation system puts other database systems to shame. However, the newbies might not know how to write a regexp that excludes a match, instead of tests for it. Understand - I''m just asking this question to help them. I have been using Regexps since ''grep'' on Xenix! But the newbies here might not know how to do this:

I''ve been working through the book ''Beginning Ruby on Rails E-Commerce'' which is very heavy on Test Driven Development. As in, you have to write tests for scaffolding methods and validations and crap like that. And then they fail. And you KNOW its the test not the method. So you spend 2x the time writing a test that has to be adapted when requirements change. You
