Part of my application should show a list of all users on the system who agreed to have their details revealed. So, I have an action like this: def view\_users @users = User.find(:all,:conditions=\>“reveal = 1”,:order=\>“login DESC”) end In the associated view, @users is an object of nilclass and the app. breaks as it tries to iterate over the @users array. However, if I include this at the top of view\_users.rhtml \<% @users = User.find(:all,:conditions=\>“reveal = 1”,:order=\>“login DESC”) %\> …then everything works as expected.Why should this be? Thanks. ---

My guess is that somewhere (perhaps an after\_filter or a partial) you’re setting @users to nil. What happens if in your controller right after that find() call you do: render :text =\> @users.inspect, :layout =\> false return Do you get all your users then? ---

Hello there, I ran into a problem with my shiny new RESTful controller. One of it’s partial templates is using a custom member action’s url helper created by map.resources, e.g. “something\_model\_url(id)”. This works perfectly when I try it in my webbrowser, but my functional test fails when it gets to “display” the mentioned partial, telling me: Exception: undefined method “something\_model\_url” for #\<#\ On line #22 of (…) Obviously the helper does not get defined. I already know that the routing is not being processed in functional tests due to performance reasons, but there must be a way to still access my partials?! So I guess I am searching for the magic “bring me some url-helpers” trigger in my functional tests. Any suggestions will be greatly appreciated! Greetings, Christoph ---

Then somewhere after your find() call, but before your view you are trashing @users… 😕 ---

Just to add a quick note about a ‘gotcha’ that bit me in the early days… Philip H. wrote: > Then somewhere after your find() call, but before > your view you are trashing @users… If you’re doing a redirect\_to, that’ll trash your instance variables. Best regarsd, Bill ---

Hi Folks, I still can’t figure out what the problem could be. It seems it’s only the singular\_url helpers that are missing, the plural\_url helpers do not lead to test failure. Did really no one else run into something like this? Greetings, Christoph Christoph O. schrieb:
