scrapy-splitvariants 1.1.0

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.
