Re: Helper in controller undefined when called


Helper methods are used in the template class (ActionView::Template),
not controllers.  If I'm reading the documentation right, putting
"helper :all" in a controller makes all helpers found in app/helpers/
**/*rb available in that controller's views.

/usr/local/bin


Hi,

I am following the hivelogic article to compile ruby on snow leopard.
http://hivelogic.com/articles/compiling-ruby-rubygems-and-rails-on-snow-leopard/

It says to set the path of the terminal to:
export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:
$PATH"

Until this part is fine.  The problem is that when I continue creating
the folder:
mkdir ~/src

it creates the folder in my personal folder instead of /usr/local/bin

What I am doing wrong?

The ~ character represents your home directory, so that's exactly
what you're asking for.

Why do you think there's something wrong?

Do you have a particular reason for wanting to do it this way?  If not, 
then forget about Hivelogic and use Apple's Ruby.

Best,

Getting blank 404.html and 500.html pages


Hey guys.  I've a pretty experienced Rails developer, but I've never
seen this one before.  I'm not getting my custom error pages to serve
up under Passenger.  They worked just fine in an earlier version of my
app, but somewhere along the way, they stopped working.  Instead, I'm
just seeing a blank white screen with no content.  There's nothing in
the logs that indicates what's going on.

Any ideas on how to debug?  Thanks!

Hi Brijesh,

I hope the following example would help you.. If not put your code 
here..

Example:

  select("post", "category", Post::CATEGORIES, {:disabled => 
'restricted'})

could become:

  <select name="post[category]">
    <option></option>
    <option>joke</option>
    <option>poem</option>
    <option disabled="disabled">restricted</option>
(Continue reading)

Have you tried viewing the source in the the browser (View, Page
source or similar) to see if there is something being sent that is not
displayed for some reason such as invalid html.

Also you could revert back to previous versions of the app till they
work again and see what was changed.
