similar to: Problem with observe_field

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 =>

I’ve been spending a great deal of time chasing this problem. Hopefully someone sees something obvious I’m doing wrong. Basically anytime I try to call fields_for from an RJS file or within a partial in the RJS file, I get the following error. My goal is simply to load a partial into a div. The fields in this partial require fields_for though. And that’s where the problem lies.

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]} %>

Ok, this is driving me nuts. I''m trying to RJS some text into a text_area which may or may not have been written in by the user. if I page.insert_html :before, :after, :top, or :bottom, it either sticks the contents above or below the text box (but never in). If I do: page[:textboxid].value = "blah" it overwrites the contents of the textbox but doesn''t APPEND to it.

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,

I have a form where the user will type in some text in a text area. When this form gets submitted, all of the info gets pushed into a MySQL table. The text area in question can have HTML and special formatting. I want to create a preview div for this. I can use observe_field to preview the formatting as they type, but I''d rather have it set so that they can click a "Preview"

How come I allways immediately run into difficult stuff when I''m trying some new programming language? Am I blind for the simplicity of Ruby/Rail, which a see must be there? Anyway, don''t try and answer this rhetoric question. I have got another one for you, seemingly difficult. I''m struggling with a n:m relationship (in a database, that is) and its join table.

I try to catch click event on radio button, but nothing is executed.... Tested with RoR 1.1.2 and 1.1.3. What am I doing wrong? <%= radio_button_tag(:city, ''Dublin'') %> <%= observe_field(:citi, :frequency => 0.5, :on => ''click'', :with => "''city='' +

Hi all, I''ve been trying to figure this out by myself and while I feel I''ve made some progress, I feel kind of stuck. Let me see if I can explain what I''m trying to do. I have a very simple form with a text box and a text area. The text in each of these will eventually make it into a row in a table in my database. For now, the value in the text box represents a

I can''t make it work. <%= text_field_tag :friend %> <%= observe_field :friend, :url => friendships_url, :on => :click %> <%= javascript_include_tag :defaults %> Raises the error:Can''t find variable Form. The generated html is: <input id="friend" name="friend" type="text" /> <script

Hi, Yet another newbie here... I''m writing an appliction in Rails, and I''ve Ajaxified my select boxes so they update dynamically. I used the "observe_field" method to monitor changes to my select box. I find that it''s kind of erratic... it updates constantly and makes the selection for me, based on where my mouse happens to be hovering when it does its

The subject pretty much says it all: I can''t?get observe_field to take a variable for a field name I''ve tried: <%= observe_field(var_name, ... <%= observe_field("#{var_name}", ... <%= observe_field(:"#{var_name}", ... No luck. Am I missing something? Thanks, : ) Jason -- Posted via http://www.ruby-forum.com/.

I have a form where I dynamically add form elements based on user input. An example is that when a user selects a "server" from a select box I add (via AJAX calls back to server) a "type" select box pre-populated with valid choices for that server. I do this by using observe_field on the "server" field and update a div on the page with the new "type"

Hi, I have the following observe field: <%= observe_field :session_treatment, :url => { :action => ''retrieve_rate'' }, :with => ''treatment'' %> This passes on the ''treatment'' variable to the action, but I''d like to pass another variable and I''m having a hard time figuring out how to write it. Any help would be

Hi - I have a view: <% content_for(:page) do %> <h1>New user</h1> <% form_for :user, @user, :url => { :action => "create" } do |form| %> <%= render :partial => ''form'', :locals => { :form => form, :genders => @genders} %> <%= submit_tag "Create" %> <%end%> <%

Hi, I need to observe a set of radio buttons but am having great trouble. My observe_field looks like this: <%= observe_field :user_select, :frequency => 0, :url => { :action => :admin_control } %> Now it works fine if I use a text_field like this: <%= text_field :user, :select, "size" => 20, "maxlength" => 16 %> But I want a radio button, and

I am using observe_field on a number of multi-selects and checkbox form elements whose values would normally come in as arrays on a normal (non-Ajax) form post. I understand that by using the :with => ''name'' I will get name=value in the request.raw_post however if the field I am submitting has mutliple values and the name is of the form ''name[]'', I get
