sqlite3 error posted by Lance Orton @ Sat, 19 Jul 2008 17:39:16 -0000

I am having the same issue using the 3rd edition book. It started when I get to the “require” steps on page 36, I get this:

irb(main):001:0> require ‘rubygems’
=> true
irb(main):002:0> require ‘sqlite3’
LoadError: no such file to load—sqlite3/database from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:32:in `gem_original_require’ from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:32:in `require’ from /usr/local/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.2.2/lib/sqlite3.rb:1 from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:32:in `gem_original_require’ from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:32:in `require’ from (irb):2
irb(main):003:0>

I moved on to the example and then got the same thing the user gave above. So I went back…

I am a complete novice so please don’t assume I know anything. I’ve been working on this for 6 hours and have tried lots of suggestions and it’s just not working. One site suggested I uninstall the sqlite3-ruby gem and reinstall it. However, on the 1st step, I get this:

lance-ortons-macbook-pro:work lance$ gem uninstall sqlite3-ruby
ERROR: While executing gem … (Gem::FilePermissionError) You don’t have write permissions into the /usr/local/lib/ruby/gems/1.8 directory.

I have a feeling this might be the root of my problem. Please help. Thanks!

PS – I installed the latest version of sqlite3 (3.6) and ruby and rails (2.1) and the rubygems and the sqlite3-ruby gem (1.2.2). One note, the directory in the library still has sqlite3-ruby gem v1.2.1 and I’m not sure why. Installed the newer gem. I followed this site for the installation.

I am looking for options for file sharing at my web site. I would like something similar to the file sharing solution at http://www.9dx.com but I am looking for something that is free. I don’t care about web site design, I’m interested in file uploading. I need a way for people to submit art work to me which I can then evaluate and post on my web site. Some of the art can be rather large, more than 20 megabytes. If anyone can recommend a solution or has experience with a solution I would be very appreciative.

Hi,

As I really don’t know the answer to this question, I am not certain how relevant or desireable this would be but I would like to see a section on database modelling tools.

I am in the process of writing a spec for a new Rails app and it would be nice to have a section that briefly covered database modelling tools, that may fit nicely with the Rails environment.

I am at the point where I am writing a database Schema specification and would love to know if there is anything that would be advantageous to use for this process, and if not then it may be worth a mention that this is the case.

Just a thought

James

I have had no problem with railsplayground but had a few probs with eukhost which mainly revolved around making sure that the right permissions existed on certain files and folders.

Railsplayground worked with both 2.0.2 and 2.1

It might be worth you googling for rails deployment instructions.

I also had an issue with MySQL permissions.

Hi there Joe,

Don’t know if you have sorted this out yet.

I recently started sliding the Rails too, also on Vista and also with MySQL.
I myself am using the 4.1.22 Community edition version.

What version are you using of the MySQL DB?
What can be the case here, is that the password must be stored using the old_password option.

Here is some reference link; I can’t remember exactly how I solved it myself, but it might give you a headstart.
old_client

Cheers,

Has anyone had success running the ADWR depot app on a web server that uses Passenger? I’m trying to do it on Dreamhost, and while my raw-domain URL gives me the RoR intro page, adding the “depot” element results in a zero-byte blank page.

Any clue? Dreamhost naturally disclaims knowledge and responsibility.

def empty_cart questions posted by Sam Ruby @ Thu, 12 Jun 2008 00:59:47 -0000

Sam Ruby — Thu, 12 Jun 2008 00:59:47 -0000

Appendix a2 covers this briefly, but if you are familiar with C/C++, there are no variable declarations in Ruby. Instead there are a few conventions. Variable names that start with a capital letter are const, and variable names that start with a colon are implicitly part of an open ended enum declaration.

Given: def empty_cart session[:cart] = nil flash[:notice] = “Your cart is currently empty” redirect_to :action => :index end

I am curious about :notice (and :cart). Where do these variables come from?
Dealing with :cart first, in add_to_cart, we have: @cart = find_cart // which returns session[:cart] ||= Cart.new

So, reverting to my C/C++ I would imagine thinking of Cart.new returning and address of the Cart object (i.e. new Cart()). Then session[:cart] would be an index into a dictionary, but what is :cart? It hasn’t been assigned… I am confused here.

As for :notice, is that an invisible parameter? Global? Same questions on assignment.

Sorry for my ignorance of the language. Feel free to point me to a doc that explains this (i will continue looking on my own as well).

I presume we wouldn’t want this migration that deletes all existing Products and inserts a bunch of test ones to run on our production database, right? Shouldn’t there be some test in here to check which database is being messed with and skip this migration if we’re in the production database? Am I missing something?

I wouldn’t characterize it as “rolling back.” Rubygems will keep multiple versions of a gem, so you can have a 2.x and 1.x version of Rails installed on the same machine and work with both. 2.x is still very new and lots of folks are still using 1.x versions of Rails. If you can’t get hold of the 3rd edition, I recommend pressing ahead with AWDWR using a 1.x version; all you need to do is what was described earlier: specify the version to use when you create a new project by adding the extra argument to “rails” at the command line, as the version number surrounded by underscores. This will also place the version to use in the RAILS_GEM_VERSION line of config/environment.rb. You’ll still learn Rails, and then be able to learn what things bits that are different in 2.0 later, especially since you already have it installed.

You can install v1.2, but I wouldn’t recommend it.

gem uninstall rails
gem install rails --version 1.2.6

The third edition is available for download now.

If you stop and restart your server, you will likely get past this problem, but that will only take you to the next problem.

Edition 2 of this book covers Rails 1.2. Rails 2.0 contains significant updates, enough so to merit a significant update of the book. Many of the examples in the second edition simply won’t work with Rails 2.0 or later.

Edition 3 of the book (currently in beta) is keeping track to the latest release. It currently is based on Rails 2.0.2 and I’m testing the code with 2.1 at the moment and only minor updates appear to be required.

creating the app as you suggested, I now get this error:

No route matches ”/say/hello” with {:method=>:get}

FYI, I get this same error before the Say controller is generated, as well as before and after the hello action is created.

What version of rails are you running (i.e., what does “rails -v” produce?) Which edition of the book are you reading? Edition 2? Edition 3? B1.2?

If you want to run mysql instead of sqlite3, it probably would be best if you generated your project with the “—database mysql” parameter, thus:

rails --database mysql demo

Boy, didn’t take me long to run into problems! I configured my Mac per the instructions on the HiveLogic site (http://hivelogic.com/articles/2008/02/ruby-rails-leopard) including MySQL.

I got my app skeleton created and http://localhost:3000 brings up the right page with both Mongrel and Webrick. However, when I try to access the SayController per ‘http://localhost:3000/say/hello’ from page 36 (I said it didn’t take me long!), I don’t get the right error. So, as a reminder, this action doesn’t do anything at this point:

—-—-—-
~~class SayController < ApplicationController<br />end~~
-—-—-—

The title of the resulting error page:’ MissingSourceFile in SayController#hello’
Further description: ‘no such file to load—sqlite3’

One question: what happened? Any help would be greatly appreciated!!!

TIA,
David

Latest AWDWR 3rd Edition: Where are ActiveResource Chapters? posted by Sam Ruby @ Fri, 30 May 2008 19:04:04 -0000

Sam Ruby — Fri, 30 May 2008 19:04:04 -0000

My bad. I meant to say three chapters on ActiveRECORD were updated to Rails 2.0.

I still expect to have one chapter on ActiveResource, but my focus on the moment is to get the body of book first to work with Rails 2.0.2 now (and soon, to Rails 2.1) and then to explore new functions.

Sorry for the confusion.

Per this email,

This is just to let you know that Agile Web Development with Rails, Third Edition (PDF) has recently been updated. You own a PDF version of this book, and so you'll be able to request and download this latest version.

Changes in this version include:

Five new chapters were updated to Rails 2.0: Depot Administration, three chapters on ActiveResource, and the chapter on routing and URLs. Numerous errata and a number of forum comments were addressed. In particular, installation instructions on Mac OS X Tiger were updated. A number of screenshot images were refreshed.

There should be 3 chapters on ActiveResource in the latest PDF… but I don’t see them… did the gerbils run out of energy?
