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 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 there, I am confused about fucntion call. After defining a function, I called it within another function. dt<-cars; #a copy of R internal dataset "cars" created; dt$cat1<-ifelse(dt$speed<20,0,1); dt$ind<-ifelse(dt$speed<15,1,2); #group variable; freqtot <- function(data,var){ attach(data,warn.conflicts=FALSE) x1 <- data.frame(table(var))

Hello, I can get the median for each factor, but I'd like another column to go with each factor. The nm column is a long name for the lvls column. So unique work except for the order can get messed up. Example: x =

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

This is driving me nuts:-) I''ve brought it down to a simplified case where I''m rendering this rjs template: page.insert_html :top, ''cat1'', "<li>Some list item</li>" According to FireBug, this is what I''m actually getting in the browser: try { new Insertion.Top("cat1", "<li>Some list

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

Hi, I am having some difficulties with matrix operations. It is a little hard to explain it so please bear with me. I have a very large data set, large enough that it needs to be split in parts in order to deal with. I can work things on these "parts" but the problem lies in adding together these parts for the final answer. So that been said, let's say that i split the data in 2
