I have a bunch of html files with partial page content. I''d like to be able to include the content of these files in my RoR views without having to change or rename them. In PHP I''d simply use include("file.html"); What is the RoR equivalent of this? render_file insists on it being an rhtml template, and render_partial requires me to rename the file. Ideally, I

Is there an easy way to deal with nil properties in templates? All I''m aware of are these methods, and it''s quite tedious and surely violates DRY. <%= @member.name unless @member.name.nil? %> <%= @member.name.to_is %> <%= "#{@member.name}" %> csn __________________________________________________ Do You Yahoo!?

I have a method that returns either a comment stored in the flash (if it exists) or a new comment. It works when I put it in my application controller: def preform_comment if flash[:badcomment].nil? comment = Comment.new return comment else return flash[:badcomment] end end However it would be cleaner to put this in the Comment model, so I tried: def

I''d like Rails to intercept the url''s of html pages in a certain directory so I can embed them in my site. I put them in public/pages and tried to catch them with a route like map.connect ''pages/:pagename'' However this only works if the file does not exist; e.g. "pages/test.html" will only be routed if that file doesn''t exist,

I have a difficulty with something that makes me think I don''t understand an aspect of Rails what. I''ve made a sort of blog site, and under each article I show the comments and a comment form.

Hello, I would like to know is there is a way to avoid poluting the views with tons of <% %> ? Like this <%= start_form_tag() %> <%= text_field_tag(''category[title]'', category.title, {:size => 20, :maxlength => 128}) %> <% if not category.parent_id.nil? %> <%= select("category", "parent_id", Category.find(:all,

Can anyone out there tell me how to add a class or id property to a link using link_to_remote? I''ve been banging my head on this for far too long. Thanks Clint

In my views, for example list.rhtml, if I try: <%= "test" %> everything works fine. If I try: <% print "test" %> then instead of outputting the page, the browser displays the HTML source code. Any ideas on what my problem is? This is my first RoR app so it''s probably a stupid bug on my part, but my Google-fu isn''t powerful to track down

Hello, I''m having a weird problem in my user model. For the change_password method I have the following: def change_password(oldpass, newpass, confirmation) oldpass = self.class.myhash(oldpass) reload passhash = self.password self.password = newpass self.password_confirmation = confirmation if valid? and oldpass == passhash save! else # valid?

I notice when issuing the command "net rpc user testuser -S ip_address -U administrator%password" that the testuser gets added to the remote machine (Win 2k3) sucessfully, however the account is disabled. After adding the user remotely it requires that the administrator log into the remote machine "ip_address" to enable the newly created account. Is there a way to add a user

Hey group, I went through the Hivelogic install and it works great. Now I''d like to run lighttpd as a daemon, but when I go into the /usr/local folder where everything was installed, I don''t see a lighttpd directory where the config files would be. If I try "lighttpd start" from the command line, I get an error that says "No configuration file available".
