We still have a few apps that store the errors collection of an ActiveRecord object in the flash[:error] hash. This always worked fine, but since switching to cookie store, sometimes we get an exception because the cookie data is greater than 4KB.
What happens is the ActiveRecord::Base object is stored in the ActiveRecord::Errors object. If this object is too big, the exception is raised.
I monkey patched the FlashNow object to nil the @base ivar in flash.now. Here is the code:
class ActionController::Flash::FlashNow def =(k, v) newv = v.clone newv.instancevariableset(:@base, nil) if v.isa?(ActiveRecord::Errors) @flash[k] = newv @flash.discard(k) v end end
class ActionController::Flash::FlashHash def =(k, v) newv = v.clone newv.instancevariableset(:@base, nil) if v.isa?(ActiveRecord::Errors) keep(k) super(k, newv) end end
This takes care of the problem without affecting any other part of the app. Just drop this code in an initializer and bob’s your uncle.
