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.
myview.erb:
<html ...>
__<%= render ''form'' %>
</html>

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

How does bundler know whether Gemfile has changed?
I am trying to understand how bundler works. Looking at the manual [1] it says
"If a Gemfile.lock does exist, and you have not updated your
Gemfile(5), bundler will fetch all remote sources, but use the
dependencies specified in the Gemfile.lock instead of resolving
dependencies."
The question is how does it know whether Gemfile has been updated? I

Comment syntax and strange partial rendering
Using rails 2.3.2 I have a partial _foo.rhtml that begins with a comment
as follows:
<% # here is a comment %>
<li><%= foo %></li>
When I render the partial from a view in the traditional way, e.g.
<% some_numbers = [1, 2, 3, 4, 5] %>
<ul>
<%= render :partial => "foo", :collection => some_numbers %>

Understanding Form_for
OK, so I''m an absolute noob at Ruby on Rails. I''ve read a lot of
information I can find about form_for and most of them use form_for to
create new items that get saved into the database and can be viewed
later to edit, destroy, etc. In this case, the database will fill up
with whatever the user wrote and I just want my program to have no
information stored.

Extremely slow start up with ruby 1.9.1 vs 1.8.7
I created a fresh new rails app, no gems, no nothing. Completely
unmodified. Doing anything that initializes rails takes 2 - 3 times
longer in ruby 1.9.1 than it does in 1.8.7. Obviously with a fresh rails
app, this is only 2 - 3 seconds extra. But with a decent sized app, this
can take up to 25 seconds for rails to initialize, vs the 12 seconds in
1.8.7.

ferret search in production
Hi there,
after recently deploying my app, I have noticed that the search
results are not being displayed...
When I look in my app, I also notice that the apps content (search
criterea) is not being indexed, so I dont have an index folder being
created.
I read on a google post that it may be that the ferret.yml server
isn''t started (or perhaps the content of this file are not right)
