Unknown action, No action responded to world


#1

http://localhost:3000/hello/world gives:

"Unknown action

No action responded to world"

I’m following along with <http://wiki.rubyonrails.org/rails/pages/
Tutorial> and what stands out are statements like:

“Now take a look at app/controllers/hello_controller.rb.”

Which doesn’t exist for me, I had to create multiple directories. I
would’ve thought that a directory like “controllers” would be pre-
existing?

Anyhow, I was getting:

"Hello#index

Find me in app/views/hello/index.rhtml"

from both http://localhost:3000/hello and
<http://localhost:3000/hello/
index>, but seem to have lost the thread of the tutorial.

I know that my .rhtml file should be using the variable which is defined
elsewhere, but it’s not clear from this tutorial how to do that
(entirely). It doesn’t specify what each file should look like in its
entirety, and I, for instance, can’t follow the instruction to “Notice
the index function,” because there’s no such function in the file which
I
created. Should I create such a function? No doubt, but the discrepancy
indicates that perhaps my configuration is mucked up. The index
function
should’ve been created by…?

In any event, here’s my decidedly primitive script which I’m using to
run
my ruby stuff, and it’s output:

MySQL (default setup). Versions 4.1 and 5.0 are recommended.

Install the MySQL driver:

gem install mysql

On MacOS X:

gem install mysql – --include=/usr/local/lib

On Windows:

gem install mysql

Choose the win32 build.

Install MySQL and put its /bin directory on your path.

And be sure to use new-style password hashing:

http://dev.mysql.com/doc/refman/5.0/en/old-client.html

development:
adapter: mysql
database: dummy
username: feeds
password: password
socket: /var/lib/mysql/mysql.sock

Warning: The database defined as ‘test’ will be erased and

re-generated from your development database when you run ‘rake’.

Do not set this db to the same as development or production.

test:
adapter: mysql
database: dummy
username: feeds
password: password
socket: /var/lib/mysql/mysql.sock

production:
adapter: mysql
database: dummy
username: feeds
password: password
socket: /var/lib/mysql/mysql.sock
def world
@greeting = “hello world!”
end
