how to get field type string from db model in django

Solution 1:

If you were doing this:

model._meta.get_field('g').get_internal_type()

You could not possibly get that as a result.

Instead, you are doing this:

model._meta.get_field('g').get_internal_type

Which, as explained here, does not call the method, it just refers to the method as a bound method object. The return value is not part of that bound method object, it's created by the method when the method is called. So, you have to call it. So you need the parentheses.

Solution 2:

You can do this:

from django.db.models.fields import *
....
if model._meta.get_field('g').__class__ is UrlField:
    ....
....

or If you want to use String instead of working only with UrlField

....
if type(model._meta.get_field('g')) is eval('UrlField'):
    ....
....

or

isinstance(model._meta.get_field('g'), UrlField)
# This will return Boolean result

You Can also use equal '==' instead of 'is'

• Model_meta
• Fields

Solution 3:

The answer is to call the method instead:

my_type = field.get_internal_type()
