        ====================
        
        A simple pluggable application that allows to work with database views.
        
        So far only MySQL is supported as backend, but more could be added if
        necessary.
        
        Quick start
        -----------
        
        1. Add "dbview" to your INSTALLED\_APPS settings like this:
        
           .. code:: python
        
               INSTALLED_APPS = (
                   ...
                   'dbview',
               )
        
        2. In your models.py create classes which extend dbview.DbView like
           this:
        
           .. code:: python
        
        
               from django.db import models
               from dbview import DbView
        
               class ModelA(models.Model):
                   fielda = models.CharField()
                   fieldc = models.IntegerField()
        
               class MyView(DbView):
                   fieldA = models.OneToOneField(ModelA, primary_key=True,
                       db_column='fielda__id')
                   fieldB = models.IntegerField(blank=True, null=True, db_column='fieldb')
        
                   @classmethod
                   def view(klass):
                       '''
                       This method returns the SQL string that creates the view, in this
                       example fieldB is the result of annotating another column
                       '''
                       qs = modelA.objects.all().\
                            annotate(fieldb=models.Sum('fieldc')) .\
                            annotate(fielda__id=models.F('pk')) .\
                            order_by('fielda__id') .\
                            values('fielda__id', 'fieldb')
                       return str(qs.query)
        
        3. Then create a migration point for your view generation, edit that
           migration and modify it, add: ``from dbview import CreateView`` and
           replace the line the call to ``migrations.CreateModel`` with
           ``CreateView``.
        
        4. Migrate your database and start using your database views.
