Using height_field and width_field attribute in ImageField of Django

Question

I have a model

class Anh_chi_tiet(models.Model):
    du_an       = models.ForeignKey(Du_an)
    title       = models.CharField(max_length=120)
    url         =         


        

Answer 1

height_field represents a property of your model which is used to store the height.

class Anh_chi_tiet(models.Model):

  url_height=models.PositiveIntegerField()
  url_width=models.PositiveIntegerField()
  url = models.ImageField(upload_to='images', height_field='url_height', width_field='url_width')

Notice height_field='url_height'
