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

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,

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/.

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, 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)

Even if luaL_error is a "no return" function for the Lua runtime, adopt also in action functions the "return" idiom recommeded for it. This also helps code analyzers in not thinking that "g" might still be null after the null check followed by luaL_error. --- generator/lua.ml | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/generator/lua.ml

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
