similar to: Form won't accept ampersand

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/.

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,

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

Greetings all. I''m using the Microsoft "NorthWind Traders" database "orders" table as test data for the Rico LiveGrid JavaScript. The problem I''m noticing is that some of the records in the "ShipName" field contain ampersands -- which for some reason are not being escaped by Rails. Rails does in fact automatically escape all of the other

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, I have been playing around with the autocomplete field in Rails 0.13. I have noticed that if I have an ampersand in the value such as "A&E", if I click on the entry in the autocomplete list, I am left with just A in the text box. I have narrowed it down to: String.unescapeHtml() in prototype.js as what strips the & and what follows it from the value. It strips it

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

Hi. I have a form with two select lists, named ''project'' and ''activity''. The content of the ''activity'' list is changed when the selected item in project changes, using ''observe_field'' where project is observed, and a div enclosing ''activity'' is updated. This works as expected. The problem is that when

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.

I am having an annoying problem displaying the labels of a select box correctly where there is an ampersand contained within the label string. On a form being rendered with the form_for helper the collection_select reads data from a Mysql 5.075 database the text stored in the database is "Surabaya & Surrounding Areas" when rendered and displayed in firefox 3.6 or safari is is

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

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/.

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,

I''m sure this is a simple problem, but I''ve been working on it for a couple days and can''t seem to figure out the correct way to structure my observe_field call. The HTML and Javascript generated all appear correct, but the AJAX call is never made. Below is the code I''m using and any help would be much appreciated. models_controller.rb def

Folks, When I use observe_field, I get a javascript error "Form is not defined". Any thoughts? __View: search.rhtml__ <label for="search">Search:</label> <%= text_field_tag :search %> <%= observe_field(:search, :frequency => 0.25, :update => :search_hits, :url => { :action =>

Hi everyone, I''ve encountered a HUGE problem, which may not be RoR-oriented, but there might be a workaround somehow. See, at this moment, I''m unable to send AJAX requests back and forth when the information contains an ampersand (''&''). In essence, request is never completed. The odd thing is that it only happens with Firefox (IE and Opera works fine).
