Hi Community....
I''m new in this game, so this might be a easy question, but I have
done my google, without result, so I will try this....
I''m learning ROR, and I''m using Patrick Lens ''Ruby on
Rails'' book.
(This is written for ror 1.x - and I''m using NetBeans 6.1 - ror 2.x -
this might be the problem...)
But...
I have made this Controller:
class StoryController < ApplicationController
def index
@current_time = Time.now
@s = Story.find_all_by_name(''sitepoint'')
end
end
and this view:
<h1>Story#index</h1>
hej
<%= @current_time %>
<%= @s.name%>
<p>Find me in app/views/story/index.html.erb</p>
And, when browsing my ''story'' (http://localhost:3000/story), I
get
this error:
undefined method `name'' for [#<Story id: 2, name:
"sitepoint", link:
"http://sitepoint">]:Array
Now using the Rails console within Netbeans, gives me this
>> v = Story.find_by_name(''sitepoint'')
v = Story.find_by_name(''sitepoint'')
=> #<Story id: 2, name: "sitepoint", link:
"http://sitepoint">>> v.name
v.name
=> "sitepoint"
No problem with ''name'' - so what is the difference ? -
Regards Jørn

Now think, what you get back from the first query, and what you get back from the second one. Then answer yourself, does Array have an ''name'' attribute?

In the second you are using "find_by_name". The first returns an array. The second returns a Story object. You can see this in the error:> undefined method `name'' for [#<Story id: 2, name: "sitepoint", link: > "http://sitepoint">]:ArraySo you either need to loop in your view over @s. ie... <% @s.each |story| do %> <%= story.name %> <% end %> Or change your controller to match what you are doing in console. -philip --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
