Where did this value in a form come from?
Newb here.
I have a form and a value that is being displayed ... and I have no idea
where the value came from.
I have done a
<%= debugger; '''' %>
in the form and, indeed, the debugger stops at the statement.
I have tried to trace through the code to see where the value came from
... and I gave up.
So ... what in Rails initializes the fields of a form?

Haml ... ending a line with a | (vertical bar)
I don''t know if HAML questions are appropriate here ... but here goes.
How does on end line to be rendered with a vertical bar (|) ?
The vertical bar is a line continuation, aparently.
Doing \| cause the vertical bar to be emitted ... as well as the
backslash.

Routes) to the fact that I get the problem, below only when I reload my
page. Clicking on links to go to the pages I want ... I seem not to

Given that it seems to be a reload that is generating an "/undefined"
path somewhere ... can anyone suggest what I should be looking for to

acts_as_taggable, undefined method 'empty?'
I''ve tried out ''acts_as_taggable'', ''acts_as_taggable_on'' and
''acts_as_taggable_on_steroids'' and all of them output "undefined
method ''empty?''" with the tag_cloud action.
I am following the guides precisely. Yet I can find no references to
this error anywhere, so I must be doing something wrong...

Commenting in an ERB without generating a compiling error
Hello,
I have the following:
<% @projects.each do |project| %>
<tr>
.
<td><%= link_to ''Destroy'', project, :confirm => ''Are you
sure?'', :method => :delete %></td>
.
</tr>
<% end %>
How can I safely comment out the TD line above? Do I have to use the

recursive expansition of <% ... %>
In a controller I have
@message = "The size is <% @a.size %>."
In the view I have
<%= @message %>
which, sadly, produces
The size is <% @a.size %>.
rather than, say,
The size is 4.
If I try
<%= <%= @ message %> %>
I get a syntax error.
Is there a solution?

YAML, UTF-8, TextMate, Notepad
This is not a question but a report on the difficulties I had and the
solution I found with respect to UTF-8, YAML::load, and Ruby/Rails.
Comments are appreciated.

I had been struggling for two days to get UTF-8 working in my Rails app.
I had/have a localization file, lib\locale\de.yml, that had iso-8859-1
encoding. I could not get that to display properly.

haml to erb - does it work with new html5 tags?
Hi,
I wanted to covert all my erb over to haml, but I use HTML5 tags like
nav, section, article, etc. Any idea if this is supported by haml?
Checked out their site, nothing mentioned there or did I miss
something. Sorry noob here.
