Description: Deletes the product. Return: Boolean; true if delete was successful. Argument: $product_id (required). The product_id or product_sku to remove.

If you have different requirements for your forum, you can add as many columns to the forum_posts table as you need. For example, you might add email, first_name, and last_name columns. It is also easy to split the forum into separate categories, such as Feedback, News, FAQ, and Help. To set up categories, add a category_id column to the forum_posts table, which references a forum category that is stored in the categories table. Then add the following code to the model: belongs_to :category def self.find_all_in_category(category) category = Category.find_by_name(category) self.find :all, :conditions => "category_id = #{category.id}" end The belongs_to mapping allows you to access the category the post belongs to; for example, post.category.name. The find_all_in_category method could be used to retrieve posts from a specific category; for example, ForumPost.find_all_in_category('FAQ').

Note that the gain in efficiency here isn t great (It s more like really, really tiny) In general (unless your program is having performance problems), you shouldn t worry about that sort of optimization too much The point is that using a try/except statement is in many cases much more natural (more Pythonic ) than if/else, and you should get into the habit of using it where you can..

// Prepare filters $product_id = '12'; // using SOAP method $results = $client->call($session_id, 'catalog_product.delete', $product_id); // returns true if delete was successful var_dump($results);

The ForumPost model created by the generate script is almost complete. We just need to activate the plugin and add some basic validations to the model to prevent bad data from being stored in the database. We will add validations for three fields: The name field is used for storing the name of the person who created the post, and must be between 2 to 50 characters in length. The subject field is shown on the forum main page and should be descriptive but not too long, which is why it is limited to between 5 and 250 characters. The body field should be long enough for the user to write a short message, but not too long, which is why it is limited to 5000 characters. We activate the plugin by adding the line acts_as_threaded to our model, and use the validates_length_of validation method to enforce the length of a field. Here are the additions to make to app/models/forum_post.rb: class ForumPost < ActiveRecord::Base acts_as_threaded validates_length_of :name, :within => 2..50 validates_length_of :subject, :within => 5..255 validates_length_of :body, :within => 5..5000 end

The product attribute set allows you to pull options and attributes assigned for products: catalog_product_attribute.currentStore catalog_product_attribute.list catalog_product_attribute.options

wisdom, It s easier to ask forgiveness than permission. This strategy of simply trying to do something and dealing with any errors rather than doing a lot of checking up front is called the Leap Before You Look idiom.

Gives a brief introduction to Rails and how to get started The application s build script, which is written in Ruby Contains your application s code, including models, controllers, views and helpers Empty by default; reusable code in the form of components should be placed here. Note that using components is generally considered a bad practice. Holds your application s configuration files, including database configuration Holds your ActiveRecord migrations and database schema files Empty by default; put the documentation for your application in this directory (use rake appdoc to generate the documentation for your controllers and models) Holds application-specific code that is reusable Log files are written to this directory Contains static files like HTML, CSS, and JavaScript files Contains various scripts for starting and maintaining your Rails application Holds your unit, integration, and functional tests and their fixtures Where plugins are installed
