Adding fields to item in scrapy from list
Adding fields to item in scrapy from list I have a long list of fields to add to a scrapy item but can't figure out how to do it. Basically I am trying to get the output of class myItem(scrapy.Item): a = scrapy.field() b = scrapy.field() But I want to create it from a list like ['a','b'] I tried fields = ['a','b'] def generateFields(fields): item = myItem() for field in fields: field = scrapy.Field() return item But that didn't work. Thanks! 1 Answer 1 You can manage it by using python magic method __dict__ pretty much as: __dict__ fields = ['a', 'b', 'c'] class MyItem(scrapy.Item): def __init__(self): for f in fields: self.__dict__[f] = scrapy.field() my_item = MyItem() And so on... Seems that my previous comment is valid for usual python classes, not for scrapy.Item class. Followi...
