    Use DictField() in Django admin

Similar to

here is a solution to implement DictFields.
##in models.py
from .forms import StringListField, ObjectListField, DictionaryField
#To use DictFields in Django admin

class DictOverrideField(DictField):
    def formfield(self, **kwargs):
        return models.Field.formfield(self, DictionaryField, **kwargs)

##in forms.py
class DictionaryField(forms.CharField):
def generate_dictfield(self, field_name, field, **kwargs):
defaults = {
'required': field.required,
'initial': field.default,
'label': self.get_field_label(field_name, field),
'help_text': self.get_field_help_text(field),
}
        defaults.update(kwargs)
        return DictField(**defaults)
    
    def to_python(self, value):
        if isinstance(value, basestring):
            value = ast.literal_eval(value)
        if isinstance(value, dict):
            return value
        raise ValueError('"%s" could not be converted to a dict.' % value)
