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 Author < ActiveRecord::Base
has_many :books
def author_age
@results = Author.find :all, :conditions => ["age = ?",
params[:authors]]
end
end
I have this on view\authors\show.html
<table border="1">
<tr>
<td width="20%"><p align="center"><i><b>Author Name</b></i></td>
<td width="20%"><p align="center"><i><b>Age</b></i></td>
</tr>
<% @results.each do |result| %> // I am not sure if this is right!
<tr>
<td><%=h @result.name %></td>
<td><%=h @result.age %></td>
</tr>
</table>
What I want to do is to display the 'name' and 'age' that the query
returned.
Please help!
