Reading settings in spider scrapy

Question

I wrote a small scrapy spider. Following is my code

class ElectronicsSpider(scrapy.Spider):
    name = "electronics"
    allowed_domains = ["www.olx.com"]
    start_urls = ['http://www.olx.com/']

    def parse(self, response):
        pass

My question is, I want to read the name,allowed_domains and start_urls using setting. How can i do this?

I tried importing

 from scrapy.settings import Settings

also tried this

 def __init__(self,crawler):
        self.settings = crawler.settings

but I got none/error. Help me to read settings in my spider?

Answer 1

self.settings is not yet initiated in __init__(). You can check self.settings in start_requests().

def start_requests(self): 
    print self.settings

Answer 2

from scrapy.utils.project import get_project_settings

settings=get_project_settings()
print settings.get('NAME')

Using this code we can read data from settings file...
