Hey I am new to RoR. I used Dan Benjamins install. Installing MySQL  
and RoR using the terminal.

I made two files. One the controller, called say\_controller and than  
I made a views file, called hello.html.erb

Instead of getting “Hello, world!” I get

SyntaxError in SayController#hello

/Users/arongrinshtein/agile/demo/app/controllers/say\_controller.rb:3:  
syntax error, unexpected $end, expecting kEND

Any ideas?

I am keen to get coding.

Thanks!

It probably is just a syntax error like a stray or missing ‘end’. Hard  
to say without seeing the controller code though.

Here is the controller code.

class SayController \< ApplicationController  
def hello  
end

I just copied and pasted from “Agile Web development with rails.”

you may not have the sqlite3 gem installed.

sudo gem install sqlite3-ruby

also make sure you run your migrations

rake db:migrate

then you should be good to go.

THANKS GUYS!

It is working. The only thing is, is there any way to configure it  
with MySQL. Is there any reason to do that?

The default database for Rails apps was changed from Mysql to Sqlite.  
Thankfully, it’s quite easy to switch your DB:

If you are starting a Rails project from scratch, run your rails  
command like so:  
rails -d mysql myapp

If you want to switch an exisiting project from Sqlite to Mysql:  
set adapter to “mysql” in your config/database.yml file.

Hope to help,

Did that. Now I get another error.

MissingSourceFile in SayController#hello

no such file to load – sqlite3

It is possible that is the case because I set RoR up with MySQL,  
following Dan Benjamins tutorials.  
[http://danbenjamin.com/articles/2008/02/ruby-rails-leopard](http://danbenjamin.com/articles/2008/02/ruby-rails-leopard)  
[http://danbenjamin.com/articles/2007/11/installing-mysql-on-mac-os-x](http://danbenjamin.com/articles/2007/11/installing-mysql-on-mac-os-x)

Any ideas how to connect it with MySQL or should I connect it with  
SQLite. Not that I know the difference.

Thanks for your help guys.
