Session[:foo] size limit?

Rails
1

Hi there,

i want to store an array of filenames in a session-variable
(session[:foo).
The problem is: if it reaches a current number of entries the
application breaks.

Is there a storage-limit of session-variables?
Is it possible to extend it?
Is there an alternative to store large strings/arrays?

Thanks 'till now
Hans

It depends on the session store you are using. The default is
CookieStore, where the entire session is in the cookie, ie the maximum
size of a session is 4k (minus some overhead).
If you got for a database backed store then you’re only limited by the
database and how you have setup the sessions table. If you find
yourself storing large amounts of data in the session you may want to
consider an alternative design (such as storing the data in the
database in a more direct form)

Do you mean something like storing the entries temporarly in a database
with action:create and delete them when not needed anymore?
… I think thats pretty much confusing to store.

Isn’t there a possability to many strings/arrays (checkbox_values) in a
variable?
How can I change the session storage?

Thank you very much for your suggestion.

With a rails app generated by a recent version of rails you’ll have an
initializer called something like session.rb or session_store.rb in
config/initializers that sets up the session

I’ve got a rails app generated by a recent version of rails but no
initializer caller session.rb … not even an entry in other
initializers.
Can it be anywhere else?

Thanks

Well that variable has to live somewhere and you don’t have a huge
amount of choices in that regard.

Previously that stuff was an environment.rb - I was just pointing that
out as a template for how you set that stuff up .
