similar to: DoubleRenderError exception

The "update" action of my controllers and under certain circumstances creates a xml file on the filesystem. Using an after_filter that only gets called after the update action I create the XML file. Problem is, I get a DoubleRenderError because the update action either calls redirect_to or render. I can get around the render call by calling performed?() but the call to redirect_to

I have a custom authentication plugin that redirects users to a login site if they aren''t already authenticated and their session hasn''t timed out. I had things working fine with straight http requests, but wanted to add support for ajax requests. I thought this would be a simple matter of replacing all of my "redirect_to <blah> and return false" calls with

I''m trying to figure out a good way to get acts_as_list and the new sortable lists to play nicely together, but they don''t seem like they''re designed to mesh well. The ajax sortable lists post a complete ordered list of ids back to the server after every change, but acts_as_list is designed to deal with diff-like changes, rather than reordering the whole list from

I have two tables ("products" and "categories") that have a has_and_belongs_to_many relationship, and I need to be able to arbitrarily sort products in the scope of a category using something like acts_as_list. Problem is, since each product can belong to multiple categories, it doesn''t work to use acts_as_list and have the "position" field be in the

I finally got around to upgrading from 0.8.2 (!!). I had a spec which looked like specify "should render abc123" do controller.should_render :text => "abc123" get :key end With 1.0.0, the new spec is it "should render abc123" do get :key response.should render_text("abc123") end However it doesn''t work, giving me the error: undefined

Hi, I''m starting to use GetText and have this code: render_text %(<script language="JavaScript" type="text/javascript"> parent.mainframe.onUpdateNew("Gallery <b>#{@media.name}</b> was successfully created.", "#{@media.name}","#{String(@media.id)}","#{@media.media_type}"); </script>) I need to convert

I''m really new to Ruby on Rails, and I''m trying to read an XML file with REXML. No matter what I try, I am only getting the last result returned from my query. I should be getting 365 results. Here is the code: include REXML require ''rexml/document'' require ''rexml/xpath'' class MakeFootprintController < ApplicationController def index

why does <%= render_text "hey ya" %> cause ''undefined method `render_text'' for #<#<Class:0x3851120>:0x3851000>'' can i use render text in a template? -- Posted via http://www.ruby-forum.com/.

I am running (testing) a noob-tube for myself as follows: Windows XP SP2 lighty ruby 1.8.x rails 1.1 scgi I have everything working fairly well, but with one minor exception: the actions that I have defined as follows are not found. class MytestController < ApplicationController def index render_text "Hello Nurse!" end def dilbert render_text "Dilbert

Question about the list in general: by default, it''s set up so that replies go to the sender, rather than the list. However, on other lists I usually chat on, replies by default generally go to the list. This seems to encourage more discussion. Would it be a good idea to change that default? Or am I just crazy.

I have been using multiple observers, i.e., observe_field(), on the same input field and relying on them to execute in the same order that they appear in the page. This has been working fine in FireFox, but it does not seem to work in MSIE; the requests come in and are processed in a different order. Now, I''ve always been a little hesitant about using this technique, but it always

Hi R-list, I'll apologize in advance for (1) the wordiness of my note (not sure how to avoid it) and (2) any deficiencies on my part that lead to my difficulties. I have an application with several stages that is meant to simulate and explore different scenarios with respect to product sales (in units sold per month). My session info is at the bottom of this note. The steps include (1) an

Hi According to rdoc: value - the cookie''s value or list of values (as an array). So, I can use arrays, briliant. But.... It does not work (at least on webrick) I wrote a controller: def check_cookies_first cookies[:chef] = {:value => ["first", "second"], :expires => Time.local (2020)} render_text ":)" end def

I have also posted this on IRC. I have a linux host running stock RHEL 5.4 Samba 3.0.33-3.15. The host acts both as a Samba server and does a CIFS mount of that same share. The reason for doing this is so that programs running on the Linux host have the same case insensitive view as the Windows clients. I have nocase set in the relevant line in /etc/fstab I have case sensitive = No set in the

Hi, I''m baffled by this error. I need a simple controller to send e-mails, so first I thought about just creating the controller manually (without using script/generate), since that didn''t seem to work, I created a dummy table in my DB and used the usual procedure to generate scaffold code. Then I modified the controller to have only two methods, send and compose: class

Hi, I have a selectbox that updates a given span area when a user selects a value. The selectbox has the option :include_blank => true. The controler will fetch the ID of the selected option in the combo box and sends the description of the item with the same ID. The problem is that the user is able to select the empty option, and the controler will not be able to fecth the ID. This
