Hi all - hope you're well and having a great new year. I have a Rails
2.3.5 app with which I need some help. I appreciate any guidance. Thanks
in advance!
REQUEST belongs to PRODUCT
PRODUCT belongs to CATEGORY
CATEGORY has many PRODUCTS
PRODUCT has many REQUESTS
User hits form: create_request.html.erb
User selects a category, then the products select list is populated (like
Railscast 88 - dynamic select boxes)
What I now need is to render different partial forms based on which product
is selected. I suck at jquery.
-------------------------------------------------
*create_request.html.erb:*
<%= javascript_include_tag "dynamic_products.js" %>
<% form_for :request, :url => {:controller => :requests, :action =>
:create_request, :id => params[:id]} do |f| %>
<label>Select Category:</label>
<%= select( "request", "category_id", Category.find( :all).collect { |c|
[c.name, c.id] })%><br>
<div id="product_field">
<label>Select Product:</label>
<%= select( "request", "product_id", Product.find( :all).collect { |p|
[p.name, p.id] })%><br>
</div>
* ####
here's where I need help, like so:
if request.product_id = 1, render partial _form1
if request.product_id = 2, render partial _form2
####*
<button type="submit">Submit</button>
<% end %>
-------------------------------------------
*dynamic_products.js.erb:*
var products = new Array();
<% for product in @products -%>
products.push(new Array(<%= product.category_id %>, '<%=h product.name
%>', <%= product.id %>, <%= product.active %>));
products.sort()
<% end -%>
function categorySelected() {
category_id = $('request_category_id').getValue();
options = $('request_product_id').options;
options.length = 1;
products.each(function(product) {
if (product[0] == category_id && product[3] == 1) {
options[options.length] = new Option(product[1], product[2]);
}
});
if (options.length == 1) {
$('product_field').hide();
} else {
$('product_field').show();
}
}
document.observe('dom:loaded', function() {
categorySelected();
$('request_category_id').observe('change', categorySelected);
});
