Ruby on Rails
Tuesday, May 4, 2010
Have you created a rails application ?
What in your opinion is Post? Ruby expects to find a constant by that name. class names in Ruby are constants. constant is any word that starts with a capital letter.
If say you've written a class Post, then you must have done so in a file. You need to require that file when inside irb to load that class.

Hi All
I never worked with RUBY my fisrt time.
I'd like to run this query by IRB and see how many line it will show
me :
select codigo, nome from teste
My database is postgre 8.4
Look what i did to do it:
irb(main):006:0> Post.find_by_sql "SELECT codigo, tirulo from teste"
NameError: uninitialized constant Post
from (irb):6
irb(main):007:0>
What is going on there?
Thanks
Grato
