scrapy-dot-items 1.0.4

A Scrapy addon that allows to access arguments via the dot

Title

Description

For those who are tired to use scrapy's brackets and quotes. In one line of code this library will increase the readability of your code, make it more stable to human error. And will introduce IDEs code completion features to your scrapy items. You will be able to use scrapy items as normal python objects using dot syntax.

The regular bulky way to do it:

regular_scrapy_item['some_field'] = 42
print(regular_scrapy_item.get('some_field'))

The simple dot-items way:

scrapy_dot_item.some_field = 42
print(scrapy_dot_item.some_field)

Installation

pip install scrapy-dot-items

Usage

Apply to a single scrapy item class

You can add functionality with the dot_item decorator to a single class

from scrapy_dot_items import dot_item

@dot_item
class RealEstateItem(scrapy.Item):
    price = scrapy.Field()

dot_scrapy_item = RealEstateItem()

dot_scrapy_item.price = 1000
print(dot_scrapy_item.price)  # prints 1000

Apply to all scrapy items

You can apply this functionality globally

from scrapy_dot_items import dot_items_globally

dot_items_globally()  # now every scrapy.Item class will have this functionality

class RealEstateItem(scrapy.Item):
    price = scrapy.Field()

dot_scrapy_item = RealEstateItem()

dot_scrapy_item.price = 1000
print(dot_scrapy_item.price)  # prints 1000

Backwards compatibility

scrapy-dot-items are backwards compatible. You can install it into your old project and mix regular and dot style.

dot_scrapy_item['price'] = 2000  # you can still set and get the items the regular way too
print(dot_scrapy_item.get('price'))  # prints 2000
print(dot_scrapy_item.price)  # prints 2000
