Hello, I felt annoyed enough when having to redirect user back to their previous location in a hackish way that I wrote this plugin. It avoids storing POST and Ajax request. It also has a facility to specify actions not to store in the history. If you are interested, it''s there: http://blog.cosinux.org/pages/rails-history See you all, Damien -- Damien MERENNE

...eate the error. My code shows that this behavior doesn't occur with step(). If I use the superassignment operator "<<-" to define the dataframe "gam.jack" in the example below, I do not get an error. It seems like gam() finds gam.jack in the local environment of fxn, but step.gam() is looking only in the global environment for gam.jack. If anyone has further insight into what is going on here, I'd really appreciate it! ***Header info from library(help=gam)*** Information on package 'gam' Description: Package: gam Title...

...machine rake migrate stops after migration 3 for no apparent reason. --trace seems normal. No error is reported. Both Windows are XP SP2. They all have the same svn revision and Rails-related software, database is SQLite. I even rebooted the machine to no avail. Does this ring any bell? -- fxn

...op itself is negligible. The analogous SQL file with inserts takes about 3 seconds to load passed directly to the mysql client. I have no problem with those 45 seconds, but I would like to know why that''s that way. Do you know why there is so much difference? Is it the driver? -- fxn

...user.posts.last.title would do the right thing if title was an encrypted field. I see in the documentation of ActiveRecord::Callbacks there''s a before_save callback that looks like going in the right direction, but I don''t see the symmetric after_(read|find). Any ideas? -- fxn

...ns that modify the model such as add_to_cart redirect to another action that has a clear view role, like index, or show_cart, instead of generating the view themselves. This uses an HTTP redirect that goes to the client and returns. Is this an idiomatic way to design the flow in Rails? -- fxn

...uestions relating to the KernSmooth package. I am using the dpik function from the KernSmooth package and receive the error Warning message: In kappam * Gcounts : longer object length is not a multiple of shorter object length I saw an earlier post , but the issue was using the bkde fxn and the person appeared to be using too small of a bandwidth.
