python - scrapy how to import the settings to override it

this is my code

class Test(Spider):
    self.settings.overrides['JOBDIR']= "seen"

I got:

  File "C:Python27libsite-packagesscrapyspider.py", line 46, in settings
    return self.crawler.settings
  File "C:Python27libsite-packagesscrapyspider.py", line 41, in crawler
    assert hasattr(self, '_crawler'), "Spider not bounded to any crawler"
AssertionError: Spider not bounded to any crawler

I am extending Spider and I am not using Crawler because I don't have links nor rules to follow

I am guessing that my problem is because I didn't import the settings well and I need your help please

In order to change the settings in the spider you can:

class TestSpider(Spider):

    def set_crawler(self, crawler):
        super(TestSpider, self).set_crawler(crawler)
        crawler.settings.set('JOBDIR','seen')

    # rest of spider code
