==== Create Model ====


class Category(models.Model):
    name = models.CharField(max_length=128, unique=True)

    def __unicode__(self):  #For Python 2, use __str__ on Python 3
        return self.name

class Page(models.Model):
    category = models.ForeignKey(Category)
    title = models.CharField(max_length=128)
    url = models.URLField()
    views = models.IntegerField(default=0)

    def __unicode__(self):      #For Python 2, use __str__ on Python 3
        return self.title

==== Migrations ==== python manage.py makemigrations vfoss_news python mamage.py migrate **Whenever you add to existing models, you will have to repeat this process running python manage.py makemigrations , and then python manage.py migrate** ==== Django Admin ====


  1 from django.contrib import admin
  2 from vfoss_news.models import Category, News
  3 
  4 # Register your models here.
  5 
  6 admin.site.register(Category)
  7 admin.site.register(News)

===== Model - Template - View ===== ==== Basic Workflow: Data Driven Pages ==== There are five main steps that you must undertake to create a data driven webpage in Django. - First, import the models you wish to use into your application’s views.py file. - Within the view you wish to use, query the model to get the data you want to present. - Pass the results from your model into the template’s context. - Setup your template to present the data to the user in whatever way you wish. - If you have not done so already, map a URL to your view. ==== Import Model ==== ==== Update Index views.py ==== ==== Detail views ==== ==== Update Category Table with Slug Field ==== Add slug fied to models.py:



from django.template.defaultfilters import slugify

class Category(models.Model):
        name = models.CharField(max_length=128, unique=True)
        views = models.IntegerField(default=0)
        likes = models.IntegerField(default=0)
        slug = models.SlugField(unique=True)

        def save(self, *args, **kwargs):
                self.slug = slugify(self.name)
                super(Category, self).save(*args, **kwargs)

        def __unicode__(self):
                return self.name

./manage makemigrations vfoss_news ./manage migrate Auto populate slug field. Add following to admin.py


from django.contrib import admin
from rango.models import Category, Page

# Add in this class to customized the Admin Interface
class CategoryAdmin(admin.ModelAdmin):
    prepopulated_fields = {'slug':('name',)}

# Update the registeration to include this customised interface
admin.site.register(Category, CategoryAdmin)
admin.site.register(Page)
