ruby on rails - Passing large data sets between forms? -

i'm trying build step step form transforms large sets of data in batches. want have data saved database on last step. way i've seen create forms save data in session storage.

session[:stored_data] = large_dataset 

but gives me cookieoverflow error when trying save it.

what other options? stuck saving data database between steps?

you store in form itself.

on first form might have...

<%= f.text_field :name_of_dog %> 

...and on second form store first form's fields in hidden field.

<%= f.hidden_field :name_of_dog %> 

this way carry data through subsequent forms , when final form submitted, have complete data need persist database.

i single db records amount of information may overwhelming end user or when you're displaying limited amount of record data per page (say, because you're in iframe).

i have attr_accessor called :page when create or edit action called know page has submitted.
