How to organize complex attributes in Magento?

Question

Magento

This is my first time making a magento site, so this question may seem strange.
Foreword
there is a site nprom.ru At the moment I am rebuilding it on magento.
The problem is, I don't know how best to implement the compound goods scheme and filtering by parameters.
let's say we have a regular category
nprom.ru/index.php?id=12&type=&ntype=%CD%E0%F1%EE%...
each product has parameters for pressure flow and so on. But these parameters have many values, how can we implement a filter with a head of 80-120?
And the second question. There are categories of goods where pumps are supplied with different engines, and there, depending on the engine, the parameters and price change. How can this be implemented? Is it possible to do this with regular functions or will I have to add something? (including how to build a filter)
here's how it looks like
nprom.ru/index.php?id=34&type=&ntype=%CD%E0%F1%EE%...
only without filters and so on.
ps I read the documentation, but I did not find the answer to my question. Everywhere there is a difference. Need advice from experienced people on how to do this.

Answer 1

If you didn’t find the answer, then you just didn’t read well, but in general you just need to have experience.
What you describe is not a complex attribute, there is no such thing. There is a concept of a custom product (Configurable Product). In your example, you need to add attributes through the admin panel
, for example, for the Head characteristic, add an attribute, determine the scope, select the appropriate type of integer or decimal number, set other properties, such as use for the filter, etc. And it will calculate the filtering ranges itself from min to max from the current selection.
On the second question, it can be implemented in several ways, but it depends on the presentation in the store, if it is the same pump model and only the engine changes, then this can be implemented through the types of goods, but I won’t tell you exactly which one now, there is little introductory information. Specify the engines are sold separately and each has its own part and are they interchangeable? Alternatively, multiple motors are model-specific, meaning that each pump model only has a limited set of compatible motors for installation. All these requirements must be taken into account.

How to filter products by attribute:
1. Create all necessary attributes - www.magentocommerce.com/knowledge-base/entry/tutor...
The Catalog Input Type field must be set to “Dropdown” in order for the attribute to be used in filters (layered navigation)
2. Create a set of attributes called, for example, "artesian pumps" - www.magentocommerce.com/knowledge-base/entry/how-d...
3. Create ordinary simple products.

In short, in Magenta, you will need to create each variation of the product yourself, simply specify different values ​​of the changing attributes. And then you create a Configurable product and put all your options into it. In your case, only the power attribute will change.
