Pls help me...I want to save scraped data automatically to my database(cleaner version)

Show key headers only | View raw

[Multipart message — attachments visible in raw view] - view raw

I have asked this question earlier but this should make more sense than the
earlier version and I don't want anyone who could potentially helped to be
put off by the initial mess even if I updated it with my cleaner version as
a reply

I want to save the links scraped to be save in my database so that on
subsequent run, it only scrapes and append only new links to the list.

This is my code below but  at the end of the day my database is empty. What
changes can I make to overcome this? Thanks in advance


    from django.template.loader import get_template
    from django.shortcuts import render_to_response
    from bs4 import BeautifulSoup
    import urllib2, sys
    import urlparse
    import re
    from listing.models import jobLinks
 #this function extract the links
    def businessghana():
        site = "http://www.businessghana.com/portal/jobs"
        hdr = {'User-Agent' : 'Mozilla/5.0'}
        req = urllib2.Request(site, headers=hdr)
        jobpass = urllib2.urlopen(req)
        soup = BeautifulSoup(jobpass)
        for tag in soup.find_all('a', href = True):
            tag['href'] = urlparse.urljoin('
http://www.businessghana.com/portal/', tag['href'])
        return map(str, soup.find_all('a', href =
re.compile('.getJobInfo')))
 # result from businssghana() saved to a variable to make them iterable as
a list
    all_links  = businessghana()

#this function should be saving the links to the database unless the link
already exist
    def save_new_links(all_links):
        current_links = jobLinks.objects.all()
        for i in all_links:
            if i not in current_links:
                jobLinks.objects.create(url=i)

# I called the above function here hoping that it will save to database
    save_new_links(all_links)

# return my httpResponse with this function
    def display_links(request):
        name = all_links()
        return render_to_response('jobs.html', {'name' : name})
 My django models.py looks like this:
 from django.db import models class jobLinks(models.Model): links =
models.URLField() pub_date = models.DateTimeField('date retrieved') def
__unicode__(self): return self.links
