python - scrapy: post some forms following scrapy finishing processing urls -


i using scrapy scrape data member's site. perform login , scrape data successfully.

however, need submit forms on site when scraping of data finished. i.e: following reading of data, want write data site scraping (reading) data from.

my question is:

how informed of scrapy finished processing url scraping, can perform form submissions?

i noticed solution - see here (scrapy: call function when spider quits) reason cannot continue yielding more requests in self.spider_closed method called on over examples can write operations.

yes, cannot continue using spider after spider_closed signal has been fired - late, spider closed @ moment.

a better signal use spider_idle:

sent when spider has gone idle, means spider has no further:

  • requests waiting downloaded
  • requests scheduled
  • items being processed in item pipeline

datatable - Matlab struct computations -

i download data yahoo! finance with: data = getyahoodailydata({'msft', 'axp'},'01/01/2000', '01/01/2015', 'dd/mm/yyyy'); and data stored 1x1 struct. want create tx2 matrix of daily adjusted closing prices msft , axp, column 7 in each table in struct. how can that? or better : there way make computations directly on information/prices in struct? you can access data in struct name. vecmsftadj = data.msft.adjclose; vecaxpadj = data.axp.adjclose; % if want n x 2 matrix madjclose = [vecmsftadj, vecaxpadj]; % personnaly prefer working table tadjclose = table; tadjclose.msftadj = vecmsftadj; tadjclose.axpadj = vecaxpadj;
