SmartScrapy

Install

pip install smart_scrapy

Setting a default value to a Scrapy Field should be as simple as the following:

import scrapy
import smart_scrapy

class SomeItem(smart_scrapy.SmartItem):

    foo = scrapy.Field(default='something')

With default value:

>>> some_item = SomeItem()
>>> print(some_item)
{'foo': 'something'}

With defined value:

>>> some_item = SomeItem(foo='bar')
>>> print(some_item)
{'foo': 'bar'}

With default value then override:

>>> some_item = SomeItem()
>>> print(some_item)
{'foo': 'something'}
>>> some_item['foo'] = 'baz'
>>> print(some_item)
{'foo': 'baz'}
