Hi all, After many days of struggling, I have a multi-model form with ajax elements more or less working, but I''m hitting a wall with a few bugs that I can''t figure out. Guidance would be very much appreciated. I''m using the Ryan Bates technique from Advanced Rails recipes to dynamically add and remove elements on a multi-model form.

I''ve uploaded the B1.12 version of AWDwR. The major changes include: - Justin Gehtland''s new chapter on Web 2.0 - James Duncan Davisdon''s chapter on deployment (this is an interesting one---JDD has strong opinions on how a Rails application should be deployed, and the chapter mirrors this. You''ll find it short and easy to follow). - I changed the

Hi, I''m trying to get act_as_nested_set working, and I''m puzzled. I googled the following http://codefetch.com/cache?url=http://media.pragprog.com/titles/rails/code/r ails-code.tgz <http://codefetch.com/cache?url=http://media.pragprog.com/titles/rails/code/ rails-code.tgz&path=rails-code/ar/acts_as_nested_set.rb&lang=ruby&qy=ruby>

So, I''ve been listing to stuff folks have been saying about the Bookman font we use. Most people like the font, but some feel there aren''t enough words/line, so your eyes move too much. So, I spent the weekend playing with typography, and I''ve come up with a compromise. The thing is: it looks good to me, but I don''t want to mess up the read for others

Using Ferret for searching, I''ve got results that I need to link to. Which is fine, except for that they''re displayed on paginated pages using Rails paginate function - so it''s not like I can''t get it from the database or anything else. Anyone have any ideas on how to go about this? It''s not so much a coding problem as a theory problem, and I

Hi everyone, I have a Department model that has_many people. How do I go about finding all departments with more than 0 people? Department.find(:all, :conditions => Department.people.size > 0) That, of course, doesn''t work, but it was as close as I could come. Thanks! Sean

I don''t know if I missed this on the list, but the Agile Web Development with Rails book is now at version 4.0, for those of us who bought the PDF from the Prag Prog site. Just a few typos and corrections from the looks of it, but can''t hurt to get the latest. You can reorder the book for download at: http://books.pragprog.com/titles/rails/reorder Cheers, Tom

I was hoping to announce this a month ago, but some legal wrangling took longer than expected.

Thank all of you for asking questions on this

Just in case some of you missed it, Pragmatic Programmers just published their first of a series of short, PDF-only books. This one is on qtRuby. It would be great to have something like this for wxRuby. I don''t think wxRuby is quite ready to this (yet), but I thought I''d plant the idea.

Hi All, I bought the ''beta book'' of Rails Recipes from pragprog and there''s a tutorial in there for producing RSS 2.0, i''d like to generate RSS (RDF) 1.0 though. Can anyone point in the right direction. I''ve had little luck finding detailed information on the ruby XML class. Thanks -- Posted via http://www.ruby-forum.com/.

I saw this mentioned on Dave Thomas''s blog http://blogs.pragprog.com/cgi-bin/pragdave.cgi/Tech/Ruby/EIR.html and don''t remember having seen it announced on this mailing list. This new Beta Book is at http://pragmaticprogrammer.com/titles/fr_eir/index.html regards Justin

Hi, I''m surprised by the solution published at the following place : http://wiki.pragprog.com/cgi-bin/wiki.cgi/Task_D-A_Dash_of_Ajax For the 4th point : the solution published make a database request for remove a Product from a Cart. I think it''s not needed. What do you all think about that ? --~--~---------~--~----~------------~-------~--~----~ You received this message

Hi I''ve been following through the example app in the FXRuby book (which has generally been very helpful!) and I''m now at the extending it stage. I''d like to get the images display at the centre of a column and have a uniform width for all columns. The centering I have fixed, but no combinations of setting width and height options and LAYOUT_FILLs seems to work to get

Heya everyone! I am quite new to Rails and I am reading AWDwR. I am at Task E "Check Out!". I understand it quite well, but I have a problem with the last playground exercise: Add a Table which contains the payment types. All goes well, but I am not sure whether I should use has_many or has_one(as in the Playground wiki at http://wiki.pragprog.com/cgi-bin/wiki.cgi/PT-E-3). I use the

Howdy, I just finished a book called Language Implementation Patterns but I ran out of room at 400 pages before I could squeeze in an LLVM example. I left a link in the book to the ANTLR wiki so I can slap something together: http://www.antlr.org/wiki/display/ANTLR3/LLVM The code is good but the description was slapped together I'm afraid (i.e., don't take it as an example of the book

Not sure if this is old news or not, but it would appear that both the Ruby Cookbook and a Rails book are now available for purchase at O''Reilly Rough Cuts (something akin to PragProg''s beta book program): http://rubyurl.com/nHz http://my.safaribooksonline.com/?mode=roughcuts&srchtext=ROUGHCUTS I haven''t tried them yet, but it definitely seems worth checking out.

i can''t get rid of the following error: ActionView::TemplateError (undefined local variable or method `order_line'' for #<#<Class:0xb75b2090>:0xb75b1f28>) on line #13 of app/views/admin/_order_line.rhtml: 10: 11: <tr valign="top"> 12: <td> 13: <div class="olnamebox"><%= h(order_line.name) %></div> 14:
