Thanks for the info guys. Now I am getting this error coming from the
author's model:
syntax error, unexpected tASSOC, expecting ')'
This is what I have in author's class
class Author ActiveRecord::Base
has_many :books
def author_age
Author.find :all, (:conditions = [age = ?,

What I want to do is to display all author's name base on the selected
age.
please, What is wrong
Thanks a lot Mr. Fred.
Now, I am having trouble with displaying the query result on
authors\show.html
I am having problems referencing the returned object and getting the two
columns displayed. The error is: You have a nil object when you didn't
expect it!
I have this in my model:
class
% @results.each do |result| % // I am not sure if this is right!
tr
td%=h @result.name %/td
td%=h @result.age %/td
/tr
should be
% @results.each do |result| % // I am not sure if this is right!
tr
td%=h result.name %/td
td%=h result.age %/td
/tr
% end %
I made those changes, but I am still getting this error: You have a nil
object when you didn't expect it!
It is pointing to the line with the loop:
% @results.each do |result|
My model look like this:
class Author ActiveRecord::Base
has_many :books
def author_age
@results = Author.find
It is pointing to the line with the loop:
% @results.each do |result|
So for one reason or another @results is nil
Most likely your query doesn't return any records.
(btw: you better name that @authors instead of @results for
readablity)
So what is in params[:authors] ?
Where does this param
The problem could be the query because when I search for one record, it
works.
So, this works fine without the query and the loop.
tr
td width=20%p align=centeribAuthor Name/b/i/td
td width=20%p align=centeribAge/b/i/td
/tr
tr
td%=h @author.name %/td
td%=h @author.age %/td
/tr
% end %

In SQL, the query will be:
SELECT name, age
FROM authors
WHERE age = 'the selected age' // the value, not the id of the selected
age.
So
I think you can find that answer here:
