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 way to suppress the Double Render Error: "ActionController::DoubleRenderError. Render and/or redirect were called multiple times in this action. Please note that you may only call render OR redirect, and only once per action." Ideally, I would like the last redirect/render called to be the one that is actually used when the page is sent to the browser. -- Posted via

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/.

Hi, This is more of a Ruby question than Rails. I want to autolink url''s in a given string. I''m not great with regular expressions and I wandered if anybody has an example. Thanks.

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

Hi I''ve contributed a patch which fixes an incorrect example in the documentation for auto_link in ActionView::Helpers::TextHelper. The example uses truncate in the old style of tuncate(text, length) which no longer works, so I''ve patched it to use the new tuncate(text, :length => n) style.

Hi, I have the following problem that I can''t seem to figure out. I want to able to fetch some text from my database record in my controller, and then add two links within the text and then send that back to the view to get rendered so that the two links appear as links and when clicked on, they''d basically call the corresponding action for the link. Would anybody know how to

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,

I have a model that deals with HTML and I want to use the text_helper.sanitize method to strip the HTML of Javascript. However, it doesn''t appear that I can get easy access to the text_helper methods from within a model. Anyone have any suggestions for how to do this? In general, I think that there are some ActionView helpers which are generic enough to want to use in a model class.

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''m using simple_format to format and display posted content from users. This content sometimes has urls in it. The problem I''m having is that if the urls are long enough to wrap, they do, but the url gets split with a <br> tag. Then, if the user clicks on the link, only the first, non-wrapped part of the link gets posted to the browser... and that''s an invalid

Hi, I correctly see: image_tag url_for_file_column("element", "picture_url", "medium") now I need to make it a link so I''ve used: <%= link_to(image_tag url_for_file_column("element", "picture_url", "medium"), {:controller => "products", :action => "sec_level", :level_id => @element.id}) unless

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

My understanding was that using the :post=>true on a link_to() was supposed to prevent search engine crawlers from triggering the link. However, this does not seem to be working for me. Is there something else that I should be/can be doing to accomplish this? Thanks. -Matt -------------- next part -------------- An HTML attachment was scrubbed... URL:
