similar to: handling navigation tabs - use sessions?

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

I''m currently using CSS to style my navigational menu. I also have jquery at my disposal. The basic structure is like this: <div id="nav"> <div class="inner-container"> <div id="wrap"> <div class="inner"> <h2> <span class="h-ico

this seems so stupid, I keep thinking I''ve dealt with this before but I have this code <h1>Portraits</h1> <% if @image.portrait == 1 %> <%= image_tag(url_for_file_column ''image'', ''file'', ''thumb'') %> <% else %> <h1>Landscapes</h1> <%= image_tag(url_for_file_column

To start out I''ll say that this is the first thing that I''ve ever built that''s been intended to programmatically send email. I''m looking at examples in AWR and also on the wiki.

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

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

Greetings, I''m in the throws of deploying an app on site5, and I''m getting strange errors. I think I might need to understand how error_messages_for works. I get a pretty standard looking error: " You have a nil object when you didn''t expect it! You might have expected an instance of ActiveRecord::Base. The error occured while evaluating nil.errors Extracted

Greetings, Does anyone have experience with Rails VPS hosting? I''m basically looking for a hosting reseller option so I can have control of my clients domains and hosting. I''m looking for something easy to use; although I like learning it all, and am learning a lot, I am most definitely not a command line linux user type as of yet. The one that I''ve looked at

Did a quick search, but didn''t come up with anything definitive. So what does everyone think is the best low maintenance and most hassle free way to go for deployment? Is lighttpd still everyone''s choice? I remember seeing one that was a pre-packaged environment with apache I think. Anyway, just about to deploy an app and thought I''d ask suggestions - want to see

Hi I am trying to get my head around how you would "efficiently" do a left-hand navigation menu structure derived from various database table entries. Example is loosely based on AWDwR''s depot app. Say you wanted to instead to have the left-hand nav links show the following: Books book title 1 book title 2 ... CDs CD title 1 CD title 2 ... with

I''m having some trouble with an instance variable being read as nil in my app. I have an image uploading, that can be added to categories. The page loads up initially fine, and if I upload an image without errors everything works fine. I''m working on the validation, but with the code I have if their are validation errors it renders ''new'' again, but reads

I am trying to use CoPilot navigation. The program installed just fine, but wine seems to be missing irprops.cpl. When I try to run the program using "wine copilot.exe" it gives me this error. > err:module:import_dll Library DEVMGR.DLL (which is needed by L"C:\\Program Files\\Alk Technologies\\CoPilot Laptop\\App\\irprops.cpl") not found > err:module:import_dll Library

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

Greetings, This might be a pretty basic question not even totally rails specific, but how do I control text editing using ruby on rails? For instance, I am using the ruby forum http://www.ruby-forum.com/topic/new as I type this and am typing into a textarea tag. I have this in my rails app and I want to know how to save the formatting - such as when I hit returns to go to a new line when I

I''m doing some searching for deployment options, and I feel like I''m getting buried in a lot of new technology and assumptions that I know all that it''s dependent on. In the past I''ve done small things with PHP where I just dump the app in a folder and everything works out of the box. I found that everyone is using Capistrano, which relies on Subversion

Calling function "sqlFetch" in library(RODBC) and specifying a character string as 2nd argument, I get an error I don't understand: library(RODBC) channel <- odbcConnect("mydatabase.mdb", case="msaccess") sqlFetch(channel, "mytable") # this works fine tabname <- "mytable"; sqlFetch(channel, tabname) # this gives an error: # Error in

Hi all, Does anybody know the easiest way to import excel data into R? I copied and pasted the excel data into a txt file, and tried read.table, but R reported that Error in read.table("data_support.txt", sep = " ", header = T) : more columns than column names Thanks! Ling

Ok, This sounds like it should be easy but I am having a hard time with it. I am making a website but I''m trying to make everything in it fairly database driven, this is really pretty much my first rails project.
