Render partial generate unwanted spaces
Hello, I have a problem with the render :partial method in all my
rails webapplications. I noticed that using render :partial will
generate spaces (mainly top spaces) on the elements inserted.
As all my websites are seperated by module (basicaly header, content,
menu, footer) it''s quite a problem as I have to set negative margin-
top to various parts for the site to display as expected

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...

Comment.all returns array of what?
I have a bad feeling asking this but I did not manage to find an answer
myself :/
@comments = Comment.all
@comments is an array.
I can for example access comment.created_at directly, or I could do:
<% @comments.each do |comment| %>
<%= debug comment["created_at"] %>
<% end %>
I expected comment to be a hash, but comment.keys or comment.values fail, as

Conditionally adding a link to a form -- how?
I''ve got two entities created by scaffolding: Expense & Vendor
In Expense#new there''s a form with a Vendors-drop-down and a NewVendor-
button.
The latter button brings up Vendor#new.
The Create button in Vendor#new brings up Vendor#show with Edit & Back
links.
I want to append a third link conditionally to Vendor#show: if the

Unindent ERB output
Hi all,
I''d like to unindent a block of ERB specifically to combat the extra
spacing being added to content inside <textarea> by the browser. Is
there such a feature in ERB?
I shall denote indentation with underscores in the pseudo code example
below.
Thanks in advance,
Khoan.

Can I omit respond_with.
If I don''t want xml results but only html can I omit respond_with in
some actions?
For example index from:
respond_with(@sectors = Sector.all)
becomes only
@sectors = Sector.all
isn''t it?

comments on HAML ?
I have been asked a couple of times at job interviews if I am
familiar with HAML or Liquid so I was wondering if maybe I should
start using them and perhaps it would make the views easier to work
with.
If I install HAML on a machine where my app is that has alot of
regular HTML in the .erb views already, will it still work with those
or do I need to convert everything to HAML ? Can I have some

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?
