I recently got a copy of the second addition in PDF and got stuck on the Ajax portion using highlighting page 128. While trying to make my cart flash I got an RJS error when I click add to cart. I have gone back and made sure my code matched what was in the book but no help. I sent Dave an email and he rec''d this list. Anybody got any good links for troubleshooting Ajax or maybe have see

Hi - another question, sorry.... I''m trying to get the highlighting effect to work on the current_item. The page refreshes fine, and then I get an error as the highlighting code is fired: page[:current_item].visual_effect :highlight, :startcolor => "#88ff88", :endcolor => "#114411" The error is: RJS Err...

Hi ! I just have a simple question. I am writing an app using rails to familiarize myself with the framework (which is pretty cool, by the way). I just wanted to know why these two work differently (since "find" should be a synonym for "detect" according to the Pick Axe) : current_item = @invoice.line_items.detect {|i| i.product.id == key} current_item = @invoice.line_items.find {|i| i.product.id == key} (The details of my project are irrelevant, I think.) The first one works, the second doesn''t. With the "find" variant, I get this error : "Couldn'&...

This is kind of frustrating (but no doubt helpful in the long run) that after following along and coding , and d/l the code the same error is appearing. For those who are familiar with the depot app, I''ve run into a problem after fixing the cart to reflect quanitites. I worked through the intended error messages but now have this appearing: SyntaxError in StoreController#add_to_cart

I thought this would be simple, but I just cant seem to get it to work. # only allow numbers. Need to check for nil / NAN def saveHours(val) if val < 0 val = 0 end return val end current_item.product.v1 = checkValue(values[:val1]) current_item.product.v2 = checkValue(values[:val2]) but when I run the code, nothing is ever returned from the checkValue function. If I remove the function call and just have values[:val1] things work fine. Ive also tried removing the return and just h...

I''m trying to implement a remove from cart method based on the examples in the second edition Agile book. I have everything working except for the RJS that removes items from the cart. Ideally what I''d like to do is highlight an element that I am deleting only if there is more than one of that particular item in the cart. If the item deleted is the only of

...have a controller called ItemController which displays information about specific items to a user on various pages. The routing looks like "items/:item/:action". Is there any way to automatically look up the :item in the items table (it''s just an ID). I tried: before_filter { @current_item = Item.find(:first, @params[:item], :include => [:set, :card]) } but apperently filters don''t have access to params. Is there any other simple way? Or is this somehow bad practice? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You rec...

In an early section on Action View, showing code being put directly into the rhtml file: <% require ''date'' DAY_NAMES = %w{ Sunday Monday Tuesday Wednesday Thursday Friday Saturday } today = Date.today %> <h1>Hello, Dave</h1> <p> It''s <%= DAY_NAMES[today.wday] %>. Tomorrow is <%= DAY_NAMES[(today + 1).wday %>. </p> I get this

..., but this is a big one - after adding the Ajax portion of the Agile Web Development tutorial my page displays: Application error Change this error message for exceptions thrown outside of an action (like in Dispatcher setups or broken Ruby code) in public/500.html It started when I added - page[:current_item].visual_effect :highlight, :startcolor => "#88ff88" , :endcolor => "#114411" Since the page is not giving any specific errors , and there is nothing in 500.html I''m not sure where to look. I did check the development.log after rebooting Webrick and see this: C...
