Hi all,
i have a question on scrapy -> django integration.
i have this models on django:
from django.db import models
from django.utils import timezone
import datetime
class Job(models.Model):
title = models.CharField(max_length=100)
description = models.TextField(max_length=500)
url = models.URLField()
pub_date = models.DateTimeField('date published')
rand_ord = models.FloatField(default=0)
def __unicode__(self):
return self.title
def was_published_recently(self):
return self.pub_date >= timezone.now() - datetime.timedelta(days=1)
was_published_recently.admin_order_field = 'pub_date'
was_published_recently.boolean = True
was_published_recently.short_description = 'Published recently?'
class Attribute(models.Model):
description = models.CharField(max_length=50)
def __unicode__(self):
return self.description
class JobAttribute(models.Model):
attribute_id = models.ForeignKey(Attribute)
job_id = models.ForeignKey(Job)
value = models.CharField(max_length=50)
and i'm going to write the pipeline.
In scrapy i have items:
from scrapy.contrib.djangoitem import DjangoItem
from jobs.models import Job, JobAttribute, Attribute
class JobItem(DjangoItem):
django_model = Job
class JobAttributeItem(DjangoItem):
django_model = JobAttribute
class AttributeItem(DjangoItem):
django_model = Attribute
in my spider i have:
item = JobItem()
item["url"] = response.url
item["title"] = 'something'
item['pub_date'] = 'something'
item["description"] = 'something'
item.save()
Everythings work fine. But now i want to save JobAttributeItem too:
item_jobattribute = JobAttributeItem()
item_jobattribute['job_id'] = 'want a job object'
item_jobattribute['attribute_id'] = 'what a attribute object'
item_jobattribute['value'] = 'something'
item_jobattribute.save()
how can i do this?
Thanks a lot
