Hello! Today blog post is aboutDjango Haystackand how to integrate it quickly withElasticsearch.
First after creating django project (At beginning of 2016 django-haystack don't work properly with django 1.9 so I used 1.8.9 version) and making new app let's add models:
fromdjango.dbimportmodelsGENDER_CHOICES=(('Male','Male'),('Female','Female'))classPerson(models.Model):first_name=models.CharField(max_length=100)last_name=models.CharField(max_length=100)gender=models.CharField(max_length=10,choices=GENDER_CHOICES)email=models.CharField(max_length=100)ip_address=models.CharField(max_length=100)def__str__(self):return'{first_name} {last_name}'.format(first_name=self.first_name,last_name=self.last_name)And register model to the admin site. Don't forget about adding created app to settings.py and making manage.py makemigrations and manage.py migrate after it:
fromdjango.contribimportadminfrom.modelsimportPersonadmin.site.register(Person)Then create simple script wich will load a data from JSON to the database. This JSON data is randomly generated data from this webpage. Call it load.py and place in your django application folder.
# coding=utf-8importosimportjsonfrom.modelsimportPersonDATA_FILE=os.path.join(os.path.dirname(os.path.dirname(os.path.dirname(__file__))),'MOCK_DATA.json')defrun(verbose=True):withopen(DATA_FILE)asdata_file:data=json.load(data_file)forrecordindata:Person.objects.create(first_name=record['first_name'],last_name=record['last_name'],gender=record['gender'],email=record['email'],ip_address=record['ip_address'])print(record)This script looks for file MOCK_DATA.json. Then based on fields on this JSON loads data to the django application. You can run this by manage.py shell and then:
>>> fromdjango_appimportload>>> load.run(){'ip_address': '86.24.99.139', 'gender': 'Female', 'first_name': 'Christine', 'last_name': 'Cunningham', 'email': 'ccunninghamrq@howstuffworks.com'}{'ip_address': '250.20.255.181', 'gender': 'Male', 'first_name': 'Scott', 'last_name': 'Hanson', 'email': 'shansonrr@utexas.edu'}# rest of the recordsThat's all for this week. In next post, I will concentrate on how to setup Elasticsearch and django-haystack.
