Sorry for the cheesy topic name couldn''t resist.
B4 I go into details I''m rocking Rails 1.2.6. I''m hosting on
MediaTemple
and they seem to working on some issue between their grid servers and
2.0.
I''m struggling with pagination. I spent a few hours discovering that
everyone thinks you should use a plugin to do your paginations. It seems
will_paginate is popular so I settled on that. It seems to have
installed just fine - all the files are there and there was no errors.
However, when I insert the code it doesn''t seem to like it.
I''m new to rails so I''m sure I''ve just overlooked
something simple - if
someone can help I''d be very grateful.
in my controller I have the following code
class ThumbController < ApplicationController
model :thumb
def list
@thumbs = Thumb.paginate :page => params[:page], :per_page => 15
end
end
In my list view I have the following (btw this works fine with my simple
"@thumbs = Thumb.find(:all)" I had in my old controller.)
<div id="galleryBody">
<% for thumb in @thumbs %><a href="<%= thumb.url
%>"><img
src="/images/thumbs/<%= thumb.filename %>"
target="_blank" alt=" "
border="0" /></a><% end %>
</div>
<%= will_paginate @thumbs %>
As I say, I''ve probably just missed something dumb, but no matter how
many tutorials or examples I go through I can''t seem to figure what it
is :(
Thanks in advance to some kind soul :)

Did you look at: http://railscasts.com/episodes/51 This helps alot as the main will_paginate site doesn''t seem to work.

Hi Jon Yeah, I checked this out. It helped me set it up tho - the special conditions this guy uses threw me a little. I was hoping what I''m trying to set up is simpler. Once I get it to work this cast will really help me to move the code into the model. Cheers ps - cool name, is that a typo?

Do you have more than 15 thumbnail images? If not, just set the :per_page down to 1 or 2 and see it begins to work.

haha yeah, i wish it was that simple - there''s about 25 images in there. as I said when I display all without the Will_paginate they display fine. i''m wondering if will_paginate is note working on the server - does anyone know a simple way for me to test? Though, even more likely is I screwed up in my code ;) fredistic wrote:> Do you have more than 15 thumbnail images? > If not, just set the :per_page down to 1 or 2 and see it begins to > work. > If you have no images don''t expect much;-) > > fredistic-- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

When trying to figure out what could be your problem with will_paginate I come to conclusion that something is fishy with your Thumb model. If Thumb.find(:all) is working than the only reason that will_paginate won''t perform should be that limit-offset query that is used is returning empty record set. You should look development log file for SQL statements that are performed and you will find the way to the solution. If you can be more specific than, perhaps, we can help you even more.

Hi
I rebuilt the page the way it was - ie without will_paginate. It worked
fine as before and generated no errors in the log. Then I reverted to
include will_paginate. Now I get an error different to the log above. I
also restarted my application.

Yay, I fixed it :) Dejan was right, there was something fishy in my model - ie nothing! Thanks to this post - http://errtheblog.com/posts/47-i-will-paginate I found that I needed the following code in my thumb.rb. cattr_reader :per_page @@per_page = 15 Thanks for the pointer. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
