similar to: bad move? - complex form with *many* observe_field's

Hi, I''ve got some Ajax stuff that shows more or less of a complex form based on a radio button selection. A "radio_handler" controller action is the action for a form handler. Some seemingly simple "replace_html" fires as a result of different radio buttons being chosen (which should then show more or less of the form). This all works just great on Mac Safari and

I have a new model I''ve just built. It''s associated with another model via has_many. I''m trying to create one of these obj''s for the first time and I keep getting an Argument Error as follows: ArgumentError (wrong number of arguments (3 for 0)): C:/Ruby/lib/ruby/gems/1.8/gems/activerecord-2.2.3/lib/ active_record/dirty.rb:135:in `field_changed?''

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

I don''t have Rails installed at the moment, I''d like to check myself, but it''s just a simple curiosity. observe_field fits into replacement tags <%= %>, which caught my attention because as far as I know it''s just javascript observing a field and should not stick anything into HTML. Is <%= merely used as an enabling method, or will there actually be

Hiyas I''m having a little problem with a observe_field in a partial "bokings/room_list": <%= select_tag "room_#{room.id}_grownups", options_for_select([0, 1, 2], room.grownups.length) %> <%= observe_field "room_#{room.id}_grownups", :url => set_number_of_grownups_booking_room_url(:id => room.id), :with =>

I want to use observe_form to automatically save notes in a text_area. This is the code I have: <form id=''notes_form''> <%= text_area :contact, :notes, :cols => 40, :rows => 10, :id =>''notes_text_area'' %> <%= observe_form(''notes_form'', :frequency => 1,

Hi, If i add field observers to radio button fields they trigger once but then nothing after that. I have multiple fields in a form that i need to know if one of them changes and which spedific field. Below is an example of two foelds i tested and they trigger once with the alert but then nothing after that. I also tried individual observers for each field test_yes and test_no but with the same

I''d like to use observe_field to watch a field, and then when it changes send the entire form to the server. I had been using <%= observe_field ''entity_name_''+@account.id.to_s, :frequency => 0.5, :update => ''auto_complete_''+@account.id.to_s, :url => { :controller => ''committees'', :action=>

hi group, I am making a little rails app to experiment with rails. It consists of one model, item, that represents an item on a todo list. A todo item has a description, a state (finished or not) and a due date. After changing the scaffold screens a bit, I wanted to be able to have no due date. I tried to do this by making a radio button; if ''no date'' is selected, the date

I have been trying to pass a collection_select parameter and a text field parameter to observe_field so that it watches both the parameters simultaneously. but what i can see is , when i select some value from drop down and dont write anything in text field its giving correct results.parameters are also correct passed, but just after that if i write something in text field that value also get

Hi, im looking to build a page similar to a shopping cart page. When you change the ''price'' or ''quantity'' fields, the total is calculated and displayed. There are other fields in the form which have no relation to this action. So i guess observe_form is not required. Can someone tell me what the best practise is for this?

This betrays my lack of javascript knowledge, but is it possible to watch a whole form for changes and activate some javascript when those changes occur without any remote request? That is, I want to do exactly what observe_form does, but without the ajax call actually happening. I realize I could use the form_tag :onchange parameter, but that seems to be incapable of doing things like

Hi, I''m new to rails/ruby having come from PHP and am just starting to get my head round how easy it can be :) However, can anyone point me in the right direction for dynamicaly updating a select box based upon the choice of a previous select box, without a page refresh. Any and all help greatly appreciated. Thanks -- Posted via http://www.ruby-forum.com/.

Hi all, I''m having problems with an observe_field, this is the view: <%= form_tag %> <div id="content"> <p>Customer: <select name="cliente_id" id="cliente_id"> <option value="">Select a customer</option> <%= options_for_select Cliente.find_all.collect {|c| [c.razon_social, c.id]} %>

Hi, I''m confused about how form verification with AJAX works. Let''s say I have a ''new.rhtml'' view that contains a form with two fields, and the form action is ''create''. Let''s assume that I also want to do some type of data validation on one of the two fields via AJAX before I submit the form. But since I''ve already

Hi, I have observers for a group of radio buttons, an observe_field for each radio button (I think its not possible to have one observe_field for a group of radio buttons). Now, the problem is that when I click on one radio button, all the observers get trigerred, so the method which the observe_field calls gets the wrong result. I just want that method to get the radio button that is

hi this is my htnl <html> <head> <%= javascript_include_tag :defaults %> </head> <body> <%= form_tag nil, { :id => ''search_form'' } %> <%= text_field ''recipe'', ''name'' %> <%= end_form_tag %> <div id="recipe"> </div> <%= observe_form :search_form, :frequency =>

I have been using multiple observers, i.e., observe_field(), on the same input field and relying on them to execute in the same order that they appear in the page. This has been working fine in FireFox, but it does not seem to work in MSIE; the requests come in and are processed in a different order. Now, I''ve always been a little hesitant about using this technique, but it always

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/.
