6189	"IntegrityError: Field ""may not be NULL"" even though blank=True"	Tyson Tate <tyson@…>	nobody	"Despite adding ""blank=True"" to my fields, I am unable to save them through the admin interface. I get errors like the following:

With the following model:

{{{
class Foo(models.Model):
	the_char = models.CharField(blank=True, maxlength=100)
	the_text = models.TextField(blank=True)
	the_integer = models.IntegerField(blank=True)
	
	the_time = models.TimeField(blank=True)
	the_date = models.DateField(blank=True)
	the_datetime = models.DateTimeField(blank=True)
	
	class Admin:
		pass
	
	def __str__(self):
		return ""Foo""
}}}

The following fields, if left blank, give me the above error:

{{{
the_integer
the_time
the_date
the_datetime
}}}

{{{the_char}}} does not behave unexpectedly (e.g. it allows blank values without throwing an error).
