Name Error in django class method

[Navaneethan R]

 

              The Django model I have defined a model called "File" and there i have writted a custom function which is used to split the filefield for my intention.while iterating the File object through this function i am getting "Name Error" for the file field

class File(models.Model):
     name = models.CharField(max_length=200)
     file_upload = models.FileField(upload_to=settings.FILEPATH,blank=True,null=True,max_length=1024)
     organisation = models.ManyToManyField(Organisation)

     def __unicode__(self):
          return self.name
     def public_url(self):
          if os.path.exists(self.file_upload.path):
              return '/site_media/'+str(self.file_upload.path).split('/site_media/')[1]

Trace back:

>>> File.objects.get(pk=1).public_url()
Traceback (most recent call last):
 File "<console>", line 1, in <module>
 File "/work/ws/intcen/gridlex_intelligence/intelligence_centre/models.py", line 52, in public_url
 if os.path.exists(self.file_upload.path):
 NameError: global name 'file_upload' is not defined

And sorry for the extra e-mail, but I just realized your code isn't abiding by PEP8 [1].

Please read through it and try to follow some of the basic conventions, such as adding spaces after commas, adding spaces around operators (such as +) and splitting lines so that they're not longer than 79 chars (72 chars for long comments and strings).
