I''m dynamically generating menu options based on the currently logged in user: current_user. My menus are setup on the applicatin.rhtml file. The current_user is defined in the application controller. But, attempting to assign it a value while in the application controller results in an ''undefined method'' error. ApplicationController .... def current_user @cu =

What is the best way to implement a ''Down for Maintenance'' page across your Rails app? Ideally I would like to have a button in my admin section that toggles the display of a ''currently under maintenance'' page to every public request to the app (possibly with some dynamic content like estimated down-time) except for: - - requests from a specified IP

I have some code working that lists only items from a particular user. The code in my list action finds the user and then conditionally lists only his/her items: def list user = User.find(session[:user]) user_id = user.id @product_pages, @products = paginate :products, :per_page => 10, :conditions =>[''user_id = ?'', user.id]

Thank you in advance for your help. I am relatively new to both Rails and Rspec and I am hoping for some insight from some experienced veterans. Right now I am using Rspec for code that has already been written so that additional functionality can be developed using the BDD method. My problem shows up when I try to spec controllers that are behind the login system. Each page checks for the

Hello! I''m releasing an extraction from an application I''m currently working on. It''s a small library for dealing with points and polygons, called Polygons. It really just implements some textbook algorithms w/ Prototype-style JavaScript classes. Check it out here: http://polygons.mdaines.com/ The demo on that page (Firefox/Safari only right now) uses the

I''m releasing a very small plugin that allows you to specify default values for fields in models. Ordinarily, you might do this in your schema, I guess, but then it''s awkward if you need that on a serialized field or need your default values calculated somehow. So you can do something like this: (repeated from an earlier post and the README) class Mixture <

I am currently caching a page that indexes blog entries. Paginate was used to break the entries up. Now when you click on next at the bottom of the page it is only reloading the first page. Im hoping, against odds, that someone here knows of a way to make paginate and cache play together. -- Posted via http://www.ruby-forum.com/.

Hey All, I have a fairly basic question about the prototype.js library. First, I''ve been looking for documentation on this and I have yet to find it. If any of you know of any, please let me know. Since I''m new to both the scriptaculous and prototype libraries could someone explain why I would want to use the cumulativeOffset method and not to just grab the offset off

Hi all, I''m using Goldberg, an engine that provides roles based access control for my app. I need to login before I can do controller tests, but I can''t find any examples of people doing this. Could someone point me in the right direction? I thought the simplest way would be to either call the login action from my other tests before(:all), but I can''t seem to

One more question: Is there some way to set the human_name of a column? e.g.: human_name for column address1 shouldn''t be Address1 but "Address, line 1". If not, should I make a hash with my custom names?

Hi, I''ve been playing around with using DBI instead of ActiveRecord ''cause I just love to beat myself up! ;) Is this an okay way to do this, or is there any other more creative ways? require ''dbi'' module MyApp:Models class DB def self.dbh DBI.connect(''DBI:Mysql:dbname'', ''username'',

Hi All: Just curious if anyone has figured out how to set a default date for the date_select helper. My application has a form with both a start date and end date select for the user. Since the period between the two is a minimum of 24 hours I wanted to have the start date default to Date.today (which it does automatically) and then have the end date default to the following date (i.e.

Hello, How can I catch the onmouseup event outside the ducument - means when the pointer is above window chrome (e.g. toolbar)?

I had a beginner''s question. I am testing the create action on my controller. I wanted to fetch the ID parameter of the newly created object, so that I can make some assertions on it. But I can''t seem to find an elegant way of doing that. Of course, might create action redirects. That means that @response.redirect_url is something like "/show/8". So I could pluck

I apologize if this is a very simple question; I''ve searched the forums, wiki, Google, and Agile Web Development with Rails to no avail. Is there a way to put conditional validation in the model? For instance, if I want to limit items a user can add unless the user is an admin? My current code is: validates_uniqueness_of :user_id, :scope => ''event_id'',

wondering if anyone tried this patch. (i havent, seeing as its 1228 lines long, 10 months old, and cant take serious a patch many orders larger than competing web frameworks) in many cases i want to keep about 10 things around, eg recent searches, new items (spanning multiple classes), referers, page views, without logging them for perpetuity. so i guess this isnt a normal queue, more like a

I love the routes feature for RoR...until now. I''m trying to write tests to make sure my urls are correctly mapping to the routes I expect them to map to. This is driving me nuts because I simply can''t get any of my tests to pass. I have thus concluded that routes must work differently than I thought. I will try to explain my understanding of how routes work. Via this
