Hi, I am new in this django, but I have already tried a few examples
I found on the web, but I have some doubts and queries:

Given the following classes:

Book class (models.Model):
 author =models.ForeignKey(Author)
 publisher = models.ForeignKey(Editor)
 Publication = models.DateTimeField ()
 Pages = models.IntegerField()

Author class (models.Model):
 Name = models.CharField (...)
 Nationality = models.CharField (...)

Editor class (models.Model):
 Name = models.CharField (...)
 Country = models.CharField (...)


As could perform the following query:

All books were published between 2005-2007, whose author
Be "Juan Perez" and belongs to a publisher whose country is "Spain"
