Have you ever wondered how Collection in Magento are built, containing array of individual Entity Objects of Magento? Collections are one of the most important data structure (if I am right) used in Magento. Most of the queries in Magento will result into collection, and then you will apply a foreach loop to access individual Entity Objects and their values. Today I came into a different situation where I had individual objects but needed to create a collection of those objects, so that I could return the collection from a function.

Here is a small snippet of code, yet useful, to get ordered items and its details. I’ve deviced this code a lot before and posted in Magento Commerce’s Forum as well. But felt like writting it again, so that I can have a quick refrence to it as well. Next thing, I’ve tried a lot to get all orders and their items details by single query, but have not yet come up with a solution. If you have any method of finding order and its details by a single query, then please do response. The code below first needs an order ID as it parameters to give order details.

Reporting can be a very important part of the Module you might be developing for Mageneto. If you are showing your data in Grid that’s good, but it will be better if you add XLS file generation action on that grid, so that the site administrator can see the report in paper. And if you have in paper you can visualize more clearly than on screen.

Query in Magento can be quite troublesome, if you are a starter..or non-starter. So I’ve tried to share some of the difficult queries using collection in Magento, so that it will be helpful to my blog readers and also a place where I can later refer to. Here is one of them, may not be dificult to all, but for me I had a very bad time initially, when I first started on Magento about a year ago. I had always thought to post on my blog, but when one of my collegue asked me about this I remembered and here’s the query.

In one of those time when you need to know what attributes of a product is used to make the current configurable product “configurable”, then here it goes Those configurable attributes are called as “Super Attributes”. Looking into the lower level at the Database level the attributes id are saved in the table “catalog_product_super_attribute”. In this configurable product’s Id and the attribute are saved. To get the attribute’s id you can directly write a custom query and fetch it. But to get its attribute code, attribute level you will then have to create an object attribute using the fetched id. But there is one shot option as well to do the same, in a managed Magento Way!

Creating Multiselect type of product attribute whose source will be the Magento’s core tables is pretty simple. Just go to Manage Attributes and create a new one. But if you want the attribute’s source table be a custom table, then you need to think. Some times a case pops up that the store admin wants to save custom type of data for attribute’s option and you need to manage an image according to the attribute’s option. So for each option of the multiselect attribute option there is an image associated with it. In this case one of the method to sort out the things is to create a module that gives you an GUI to save option’s data in custom table and give option to upload the image along with it. Later, use this tables data as source of the attribute for product. The first part, saving the data in custom option is not our concern. You can go through this for doing those. But the main point of this article is to use the custom source as source of the muliselect attributes.

If you want to create a custom module in Magento that has something to do with storing data into a custom table and using that later, then this is just the right post you have bumped into! I will presume that you already know about Models in Magento, what are they and how you can create them. Also I will presume that you will also know the basic module structure in Magento.
You will have to place this in your config.xml

<global>
     <ymodel>
            <class>YNamespace_YModule_Model</class>
	     <resourceModel>quotes_mysql4</resourceModel>
     </ymodel>
<quotes_mysql4>
                <class>YNamespace_Ymodule_Model_Mymodel</class>
                <entities>

Today, I had really a good chance to move Magento Shop from Development Enviournment to Product Enviornment. On that course I faced some big difficulty in moving the database. I already had the files and DB of the development enviornment, imporing DB was a PIA. I uploaded all the files, which was easy. And next thing I did was uploaded DB dumpped files to root of Magento.
