``SplitVariantsMiddleware`` is a Scrapy spider middleware used to split

single items into multiple items when they have a "variants" key with multiple values.

Example usage

=============

Let's assume your spider outputs an item with different size options

(from an ecommerce website for example)::

    item = {"id": 12,

            "name": "Big chair",

            "variants": [{"size": "XL", "price": 200, "currency": "USD"},

                         {"size": "L", "price": 100, "currency": "USD"}]}

When you enable ``SplitVariantsMiddleware``, this single item will become

2 items with the different variants values into a different item::

    {"id": 12, "name": "Big chair", "size": "XL", "price": 200, "currency": "USD"}

    {"id": 12, "name": "Big chair", "size": "L", "price": 100, "currency": "USD"}

Installation

============

Install scrapy-splitvariants using ``pip``::

    $ pip install scrapy-splitvariants

Configuration

=============

1. Add ``SplitVariantsMiddleware`` by including it in ``SPIDER_MIDDLEWARES``

   in your ``settings.py`` file::

      SPIDER_MIDDLEWARES = {

          'scrapy_splitvariants.SplitVariantsMiddleware': 100,

      }

   Here, priority ``100`` is just an example.

   Set its value depending on other middlewares you may have enabled already.

2. Enable the middleware using ``SPLITVARIANTS_ENABLED`` set to ``True``

   in your ``setting.py``.
