[Fixed]-Using height_field and width_field attribute in ImageField of Django

by

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'

I think you are misunderstanding what the height_field and width_field attributes are for.

The height_field isn’t used to change the height. It’s used to record what the height already is.

This way you can do something like 

<img src="..." height={{my_instance.my_height_field}} />

without having to read the file.

If you are trying to resize all images uploaded via an ImageField, check here:
