    3232Add a {{{__repr__()}}} function to all your models. Make it a habit so it becomes automatic. 
     33 
     34== Integer & NULLS == 
     35 
     36==== Problem ==== 
     37 
     38When you have a Field: current_zip = meta.IntegerField(maxlength=5,blank=True)

     42==== Solution ==== 
     43 
     44Add null=True:

     46current_zip = meta.IntegerField(maxlength=5,null=True,blank=True)
