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/.

Does anyone have advice on how to go about locating the cause of this error message: ActionView::TemplateError (wrong number of arguments (3 for 1)) on line #4 of app/views/products/search.rhtml: 4: <%= start_form_tag :action => ''search'' %> I don''t see anything wrong with line 4 above. Some background: I''ve made a number of changes to Controllers,

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

Native ERB in ruby, and eruby, seem to lack the -%> feature for suppressing trailing newlines. Thus erb -n script gives errors. Where is Rails ERB so I can invoke it directly? Thank you Hugh

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.

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

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

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)

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,

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)

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

I''m following Agile Edition 1. On page 148 it suggests using instance variables named after the fixture, for example: assert_equal @version_control_book.id, @product.id When I introduce this type of instance variable into my test, I get the following error: 1) Error: test_not_owner(GroupTest): RuntimeError: Called id for nil, which would mistakenly be 4 -- if you really wanted the

I''ve based my code on the Agile example for uploading files, pages 362-365. I''ve successfully loaded the Picture object to the database, but I come unstuck when trying to replicate this for a thumbnail version of the original image: thumbnail = Thumbnail.new thumbnail.name = ''thumbnail_'' + @picture.name.to_s

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,
