1). regarding the book book "agile web development with rails 2nd edition" , I am now on chapter 8, Task C+: Cart Creation, and I have encountered a new bug in following the material. as the book instructs, in order to resolve an migration issue to display my depot application, I need to clear the session.So as instructed , i issue the command ; C:\rails\depot>rake db:sessions:clear 2). what i get is : (in C:/rails/depot) rake aborted! Mysql::Error: #42S02Table ''depot_development.sessions'' doesn''t exist: DELETE FRO M sessions (See full trace by running task with --trace) C:\rails\depot> 3). i researched previous postings on this, and found something interesting from a "Peter Vandenberk" who writes: From: joe - view profile Date: Wed, Sep 13 2006 11:10 pm Email: joe <rails-mailing-l...-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org> Not yet rated Rating: show options Reply | Reply to Author | Forward | Print | Individual Message | Show original | Report Abuse | Find messages by this author Peter Vandenberk wrote:>> That syntax is now deprecated in favor of adding the following >> declaration in your model file:>> include Reloadable> See also: http://clarkware.com/cgi/blosxom/2006/03/28> Let us know how it goes! :-)> Peter3). THIS SOUNDS LIKE A SOLUTION , BUT I AM NOT SURE WHERE TO POST THIS COMMAND IN THE MODELS. AND I CANT REPLY TO HIS POSTIGN BECAUSE ITS 30 DAYS OLD, AND GOOGLE WONT ALLOW IT. 4). WHAT CAN I DO ? WHY ISNT THE RAKE COMMAND WORKING? WHERE DO I ISSUE TEH CODE SNIPPET - "INCLUDE RELOADABLE " TO GET IT TO WORK. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
