Django: List field in model?

Question

In my model, I want a field that has a list of triplets. e.g. [[1, 3, 4], [4, 2, 6], [8, 12, 3], [3, 3, 9]]. Is there a field that can store this data in the da

Answer 1

With my current reputation I have no ability to comment, so I choose answer referencing comments for sample code in reply by Prashant Gaur (thanks, Gaur - this was helpful!) - his sample is for python2, since python3 has no

unicode

method.

The replacement below for function

get_prep_value(self, value):

should work with Django running with python3 (I'll use this code soon - yet not tested). Note, though, that I'm passing

encoding='utf-8', errors='ignore'

parameters to

decode()

and

unicode() methods

. Encoding should match your Django settings.py configuration and passing

errors='ignore'

is optional (and may result in silent data loss instead of exception whith misconfigured django in rare cases).

import sys

...

    def get_prep_value(self, value):
        if value is None:
            return value
        if sys.version_info[0] >= 3:
            if isinstance(out_data, type(b'')):
                return value.decode(encoding='utf-8', errors='ignore')
        else:
            if isinstance(out_data, type(b'')):
                return unicode(value, encoding='utf-8', errors='ignore')
        return str(value)
