Use handy request.build_absolute_uri() method on request, pass it the relative url and it’ll give you full one. By default, the absolute URL for request.get_full_path() is returned, but you can pass it a relative URL as the first argument to convert it to an absolute URL. >>> request.build_absolute_uri() ‘https://example.com/music/bands/the_beatles/?print=true’ >>> request.build_absolute_uri(‘/bands/?print=true’) ‘https://example.com/bands/?print=true’
The problem is not in Django settings, but in the date passed to the model.

The least painful and indeed Django-recommended way of doing this is through a OneToOneField(User) property. Extending the existing User model … If you wish to store information related to User, you can use a one-to-one relationship to a model containing the fields for additional information.

Some may need to (re)install the python-setuptools package via their package manager (apt-get install, yum install, etc.). This issue can be highly dependent on your OS and dev environment.

There is a simple solution for you called unique_together which does exactly what you want. For example: class MyModel(models.Model): field1 = models.CharField(max_length=50) field2 = models.CharField(max_length=50) class Meta: unique_together = (‘field1’, ‘field2′,) And in your case: class Volume(models.Model): id = models.AutoField(primary_key=True) journal_id = models.ForeignKey(Journals, db_column=’jid’, null=True, verbose_name = “Journal”) volume_number = models.CharField(‘Volume Number’, max_length=100) comments = … Read more
