I''ve checked the Rails documentation but find no mention of link_to ''external url'' or equivalent. Does rails have a built in method to do this? thanks -Lindsay -- Posted via http://www.ruby-forum.com/.

Hi, Is it possible to specify multiple before filters in a controller... here''s the thing: only one set of filters is to use the :except option. Something like: before_filter :check_for_session_cookie before_filter :validate_user :except =>[''login''] which I use to a) check if the user has returned to the site and has a saved cookie holding login details b) check

I am trying to figure out how to write a conditional statement that will execute only if a specified variable is not empty. Right now my view looks like this: <dt>Building Regulations</dt> <% for link in @cat1 %> <dd><a href="<%= link.url %>"><%= link.title %></a></dd> <% end %> Action: @cat1 = Link.find(:all, :conditions

I have successfully used HABTM to create a many-to-one-to-many set of rows in one step. Now, if two objects I want to associate already exist, how do I create the join row? The Agile book mentions the ''push_with_attributes'' method. The text says this method is useful for adding additional attributes to the join row (in the example a ''read_at'' timestamp). I

Hi, I''m running the code example for ''Dynamically Updating a List'' in Agile pages 404-406: When I enter a new to-do, and click ''New Item'', a new page is rendered only displaying the new to-do just entered. This isn''t what''s expected. The to-do list with id="items" should be updated so the to-do list dynamically grows.

Is there a config flag to suppress the newline at the end of every ERB ''%>'' tag, so it would not be necessary to type ''-%> each time? -- Posted via http://www.ruby-forum.com/.

I''m rendering partial a form comprising several text_field helpers to maintain my User model. For example, the email field is: <p><label for="user_email">Email</label><br/> <%= text_field ''user'', ''email'', :size => ''40'', :maxsize => ''256'' %></p> In my controller,

If a user enters the Textile-based code for an image, say: !>graphic.png! the textile() method will successfully render a right-float image. Now, if I want to escape the user''s text using h(), the ''>'' is turned into an &amp;. Obviously, the image then fails to render in a browser. Is there a work around for this? I guess what I''m really asking

I''m following instructions in the Agile book, page 146 for testing an object update to the database. Here''s my code: def test_update assert_equal "jack@smiths.com", @user.email @user.email = "jack@smiths.org" assert @user.save, @user.errors.full_messages.join("; ") @user.reload assert_equal @user.email,

hi! with a 4GL background, wanting to learn RoR, what is the fastest learning path i should take? should i go grab a RoR tutorial, and learn Ruby along the way, or start with plain Ruby first? thanks for any inputs!

Hi, I want to type text into an input field then on enter, use AJAX to update the value of an input field elsewhere on the screen. ''observe_field'' allows me to watch a form field and dynamically update a DIV. Is there a variation or other method to allow me to update a field instead? -- Posted via http://www.ruby-forum.com/.

I think I may have found a bug with the auto_complete feature in rails: My controller has a before_filter with an except clause preventing the filter from running on a specific action. The action renders a view with a text_field_with_auto_complete field. Much to my suprise, the filter appears to run when I type data into this field! The filter is part of my security regime, so I end up with a

I have a form with 3 fields: user_id, email and password. All 3 fields are required, so I have a "validates_presence_of :user_id, :email, :password" in my model. Works, but the validation errors show up in a different order than I specificed in the validates_presence_of statement. Is there a way to specify the order in which the validations (and corresponding error messages) should

Hi guys, My start_form_tag generated form will not accept a text field containing an ampersand. For example, the text ''A & B'' is trunacted to ''A'' in the param hash. I know ampersands have to be encoded in URLs, but I''m surprised my form has a problem with this. I''ve tested this in Safari and Firefox. thanks Lindsay -- Posted via

This is a strange bug that I''ve never seen before. It only shows up when I run the app through the console (the app is Family Connection, and it works fine when run as a web app): 22$ ruby script/console Loading development environment. >> User /opt/local/lib/ruby/vendor_ruby/1.8/powerpc-darwin8.3.0/ RMagick.bundle: [BUG] Bus Error ruby 1.8.2 (2004-12-25)

Is it possible to directly access session and cookie objects from within a Model? When I try to read the session object in my User Model I get the following error: NameError (undefined local variable or method `session'' for User:Class): I could pass attributes taken from the session into my method in the User Model, but this seems to go against DRY. -Lindsay -- Posted via

I''ve just started working through ''Agile'' chapter 12 ''Testing''. I''ve followed the steps carefully, setting up a fixture and unit test to check the creation of an order. When I run the test I get the following: Loaded suite test/unit/order_test Started F Finished in 0.108008 seconds. 1) Failure: test_create(OrderTest)

Hello Rubyists, I''m in the position of being given the job to design and build a mission-critical web facing application for a small but growing enterprise. It is to be used by customers as needed, numbering in the tens up to the hundreds. It will collect operational data, particularly in a table around 50 columns wide, and potentially millions of rows deep, most fields being numerical.

I would like to call a helper method from my View to construct a sidebar menu. The menu is contextual, so ideally I would like to do something like this: View ---- <%= sidebar_menu %> Helper ------ def sidebar_menu case _calling_view_ when ''_view_identifier_'' ... build menu... end end where ''_calling_view_'' is the key that points to the
