For some reason the code doesn't work,
content_for(:list)
i'm talking about, no matter what I try
it seems to be html escaped in the output which is:
<ol> <li>This message came from the controller.</li> <li>This message came from the controller.</li> <li>This message came from the controller.</li> </ol>
and the source:
<ol>
<li>This message came from the controller.</li>
<li>This message came from the controller.</li>
<li>This message came from the controller.</li>
</ol>
How can this be solved?
I noticed that putting 'raw' in it didn't work (saw that in a stackoverflow question)
Note from the Author or Editor: rails versioning issue, now fixed in Learning Rails 3.

5th Code Example |
The second line of the code example contains:
:url => { :action => ( @person.new_record? ? "create" : "update" ) },,
The second comma causes an error in Ruby.
Removing the comma fixes the issue.
Note from the Author or Editor: Fixed.

paragraph 2, " |
The problem is that this paragraph (2nd p.133) has us do a migration:
To run the migration, just run rake db:migrate as usual. The Rake tool will find the new migration file, know that it hasn?t run it yet, and add the column to the existing :people table, as requested.
which is repeated later on page 136:
It?s time to try this code. Running rake db:migrate updates the database:
== 2 AddPhotoExtensionToPerson: migrating ========================
-- add_column(:people, :extension, :string)
-> 0.0757s
== 2 AddPhotoExtensionToPerson: migrated (0.0759s) ===============
Doing the migration the second time does not return the above result. It is actually blank because you've already done it once.
Note from the Author or Editor: Nice catch! I removed the duplication.

all over the book |
Probably a dozen references to "app/controllers/application.rb" which should actually be "app/controllers/application_controller.rb". THe one where it started tripping me up a bit was on page 265 but I did a search and found it like that all over.

1st paragraph, 1st and 2nd block of code |
Ruby code is using camelcase (aB) method name instead of snake case (a_b).
This
map.taxonomy 'taxonomy/*steps' :controller => 'taxonomy', action => 'showTree'
should be
map.taxonomy 'taxonomy/*steps' :controller => 'taxonomy', action => 'show_tree'
This
def showTree
steps = params [:steps]
....
end
should be
def show_tree
steps = params [:steps]
....
end
Note from the Author or Editor: Style issue, but yes, fixed.

Code at top of page |
This line:
@result = addThem (1, 2)
Results in this error:
/Users/jet/work/ruby/testbed/app/controllers/testbed_controller.rb:3: syntax error, unexpected ',', expecting ')'
@result = addThem (1, 2)
^
/Users/jet/work/ruby/testbed/app/controllers/testbed_controller.rb:7: syntax error, unexpected $end, expecting keyword_end
Changing the line to read
@result = addThem(1, 2)
Makes the code work (removed space).
I am using:
ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin11.1.0]
Rails 2.3.11
I downloaded the .pdf and .mobi files today just to be sure I had the latest versions.
Note from the Author or Editor: Sorry, an extra space crept in. It's been deleted!
