Hi, I have some named routes defined e.g. map.public and wish to use link_to_unless_current() to disable link. However, as I''ve seen from forum discussions and the API doc, the issue lies with the fact that the named_route_url() method generated by a named route does not default to only_path = true like url_for. Therefore, the current_page? within link_to_unless_current() will not

Hi folks, I''m new to Ruby & Rails, and have been reading the Agile Web dev & Pickaxe books with much joy! However, I need some guidance re: using migrations to load in data for tables that have relationships. For example, I have one products table and one product_photos table (defined in separate migration files). The second table has a foreign key associated with the

Greetings, I appreciate the help from here as I seem to be asking the noob questions a lot, but what is a good way to deal with navigation pulled from a database? I have this in my view: <% @nav_buttons.each do |nav_button| %> <li><a href="#" class="nav"><%=h nav_button.name %></a></li> <% end %> this in my controller def

Hi, first time posting here. I''m in the process of learning ruby and the rails framework and i''ve come to a road block. I started off by using the Onlamp tutorial online and got a test database and all of the generated scaffold pages. I am currently working on a drop down box using the select tag. I figured out how to get values from a ''name'' column in my

I think this is a fairly easy question done several times in several languages, but on a traditional ''tab'' based navigation webpage, what''s the best way to handle the active state? I am using this in my view: <% for category in @categories %> <% if the condition is met to make this the active tab %> <li><a id=''active''

I''m rewriting the code to my first app. I want to reuse a lot of it, but tidy it up a lot. The first thing I will tackle is my nav-bar. Throughout a user''s experience on my app, I want it to reload as little as possible (I''ll have about 7 or 8 controllers with about 70 actions). So, I''ve thought of a few ways of doing it, and was wondering if you guys

I have a navigation menu that contains a link per controller in my application. This menu is the same for all controllers, but I want this behaviour: <a>Users</a> <span>Statistics</span> and <span>Users</span> <a>Statistics</a> depending on the page you''re currently on. I''ve put a <render :partial =>

Hi, seem to keep running into a wall here. I can''t find any resources on site navigation that can deal with any model being in the nav, allow nesting, and can dynamically update. So I thought about it for a while, and decided on a MenuItems class, which contained the position of the child in relation to it''s siblings, where the parent and the child were polymorphic. Then a given

I am attempting to integrate a main navigation section into my web application. Naturally the easiest and DRY way to do this would be to either include it in a layout, or as a partial. The only problem is that I want the link for the current page to have its own css id ("current"). The only way I can think to accomplish this is to just include the navigation in every page, but this is

Dear R list Would anyone be able to tell me whether it is possible to do "enhanced multidimensional scaling" (enhanced MDS) in R? In other words, something that goes beyond "cmdscale" by iteratively improving the fit between observed dissimilarities and inter-object distances, using the KYST algorithm (Kruskal, 1964). I have found several implementations of non-metric MDS

Samba team, I posted the following message on May 30 to comp.protocols.smb, but no one has responded to the posting as of yet, so I thought I'd try this email list.

Dear helpRs Does anyone have an elegant way of doing the following: For a given numeric vector, e.g. vec <- c(3,2,6,4,7) Create a series of vectors where all but 1 of the values are replaced by 0's, e.g. vec.a <- c(3,0,0,0,0) vec.b <- c(0,2,0,0,0) vec.c <- c(0,0,6,0,0) vec.d <- c(0,0,0,4,0) vec.e <- c(0,0,0,0,7) I have looked at `replace', but can't think of a

Hello again I'm trying to put error bars onto a barplot.
