similar to: "Common action" for a controller

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 =

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.

Newbie question: From a _form.rhtml file I have: <%= render(:partial => ''item'', :collection => @items) %> In _item.rhtml I have: <% @tullt = h(item.body) %> <%= @itemdb = Group.find(:all, :conditions => "id = ''#{@tullt}''").map {|u| [u.name] } %> <%= @tullt % I think it would be better to

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

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''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

I feel I am very close to understanding how layouts are used in Rails: Q1. I know one can specify a "default" layout for all methods in a controller by specifying layout ''my-default-layout'' How can this be overridden for individual methods so when those methods are called/executed, the overridden layout will be used. Is this possible? Q2. With no

Hello i have several libvirt hosts (CentOS6, kvm), each with an internal libvirt "default" network with "forward mode='route'". I have two questions concerning static routes. To give some context: On each of my libvirt hosts there is a VM acting as a OpenVPN-gateway to the other libvirt hosts. [A] How can i add a persistant static route on the libvirt host to one

I have this page that you login in from. You get authenticated and then bumped over to the appropriate page depending on what your role is: Traveler, Travel Manager, Admin. All pieced work except for the role asssociated with Travel Managers who get tossed out, apprarently when they hit a before_filter to check authenication. However, it seams that they are properly getting authenticated and moved

Hi, guys. I have an issue with accessing to my sysvol share with smb2 or smb3 clients. I have an issue with editing my Group Policy from Windows 7,8,8.1,10 or Windows Server 2012 clients with RSAT installed and everything works fine when I edit group policy from Windows XP machine.

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] %>.

Hi there, I''ve been trying to paginate over a list of members that all share a tag in common using the acts_as_taggable plugin. The regular way of paginating over a collection doesn''t seem to work with acts_as_taggable. Here''s what my method looks like that takes in a tag name, finds all the members that share the tag and then displays all the members. Nothing too fancy

Hi Everyone, Is there any way to restrict Disk usages per DomU? It would be to stop customers from hogging all the available disk time and slow everyone else down. Apperently, Cloudmin can do this, but that costs money... Any ideas would be appreciated Thanks _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

I'm writing a stackable file system and one of it's features is that it can combine many sparse files into a single view. On ext2/3 I was using bmap to give me the information needed, so for instance, if I created a big sparse file and tacked on some information at the end on ext2/3 I'd get something like blade12:~# ~/a.out abc File: abc Size: 30002 Blocks: 8 Blocksize: 4096 0
