helpers

I am having an index view with several rows for items which have multiple attributes. I would like to update the content of an items attribute with ajax, therefore I need a unique dom id. Is there a helper method available? What I am doing right now is: <span id="<%= item.id.to_s + "_on_storage"%>"> Best, Phil You can use dom_id(item) Which is an ActiveRecord method for generating DOM IDs. A good practice as well is to use HTML5 data attributes: <span data-item-id="<%= item.id %>"> 来源： https://stackoverflow.com/questions/11817398/how-can-i-generate-a-unique-dom-id-for-a-html-tag-from-model

I'm trying to create a function that will retrieve an order by its ID. For some reason I can't get the WooCommerce global function get_order to work. I'm passing a valid order id to the function and trying to print it out to verify that it's working. The function has been placed in my functions.php file. function getWC_order_details($id){ global $woocommerce; $order = get_order( $id ); print "<pre>"; print_r($order); print "</pre>"; } I have tested echoing other data out of the function without a problem. First of all make function like this : function getWC_order_details($order_id) { $order =

My app consist of two executables the main app executable small console app to process some files, this executable is on Resources folder (no root privileges required) The thing is that I don't know how to submit this app to appstore, I get the following response from apple Invalid Signature - the main app bundle appname at path appname.app is signed but the signature is invalid. The following error(s) were reported from codesign: a sealed resource is missing or invalid In architecture: i386 If I remove helper app, it bypasses this error, but app won't work at all. Anyone knows a good way or

I am finding myself specifying :rows => 5 on all my text_area form helpers, So I looked up its definition and found the DEFAULT_TEXT_AREA_OPTIONS to be the hash dictating these options. However, the hash has this freeze method on it and I looked it up, it means it can't be changed. If you could recommend me some options to try to do a app-wide :rows => 5 for all text area, I'd really appreciate it. Thanks You can do: Write own helper: def readable_text_area(form, method, options = {}) form.text_area(method, options) end or redefine text_area method delegating to original text_area with proper

I like the idea of HTML helpers, which allows me not to write all the HTML for common elements, while still gives me full control, preserves model-view separation and can be strongly typed. I'm wondering if it is possible to generate CSS stylesheets or style definitions the same way - using helpers in view markup? Ideally, I would like to have some of the CSS generated based on some object-oriented rules and definitions. I can't find any solutions that will offer anything more than stylesheet compression and merging. What you're asking for isn't impossible, but the way things are configured by

I'm relatively new to Rails and a bit surprised this isn't a configurable behavior...at least not one I've been able to find yet?!? I would have thought that 99% of forms would benefit from whitespace being trimmed from all string & text fields?!? Guess I'm wrong... Regardless, I'm looking for a DRY way to strip all whitespace from form fields (of type :string & :text) in a Rails 3 app. The Views have Helpers that are automatically referenced (included?) and available to each view...but Models don't seem to have such a thing?!? Or do they? So currently I doing the following which first

I have a rails helper using the structore below, but when I use it I get the message undefined method 'link_to' The helper is arranged as: module MyHelper class Facet def render_for_search link_to("Value", params) end end class FacetList attr_accessor :facets def initialize #Create facets end def render_for_search result = "" facets.each do |facet| result << facet.render_for_search end result end end end This is because within the Class Facet you don't have access to the template binding. In order to call the render_for_search method you probably do something like <%= Facet.new.render_for
