How to override the main create method in odoo11?

I have a lot of models (around 30) that overrides the create method to check for a license state and all of them go like this:

class Model1(models.Model):
    _name='testing_model1'

    @api.model
    def create(self)
        check_license(self)
        return super(Model1, self).create(values)

Is there any way to add the "check_license" function in the main create so I don't have to write it in every model?

I see two easy possibilities:

1. Usage of Odoo's inheritance

Odoo's inheritance mechanism is also working on the base model. The following example is from Odoo V13 module base_import, but in Odoo V11 there are some examples, too (e.g. in web):

class Base(models.AbstractModel):
    _inherit = 'base'

    @api.model
    def get_import_templates(self):
        """
        Get the import templates label and path.

        :return: a list(dict) containing label and template path
                 like ``[{'label': 'foo', 'template': 'path'}]``
        """
        return []

Following is the code which you'll need (won't work in later versions because create has changed):

class Base(models.AbstractModel):
    _inherit = 'base'

    def create(self, values):
        """
        Extended core method to implement a license check,
        before creating a record.
        """
        check_license(self)
        return super().create(values)

2. Using a mixin (lot of examples in Odoo code)

It's possible to use a mixin class to restrict the license check to some models, which will inherit this mixin. The 1. concept isn't restricting it (but it is possible there too).

class LicenseCheckMixin(models.AbstractModel):
    _name = 'license.check.mixin'

    def create(self, values):
        """
        Extended create method to implement a license check,
        before creating a record.
        """
        check_license(self)
        return super().create(values)

You can then inherit this mixin in other Odoo models:

class SaleOrder(models.Model):
    _name = 'sale.order'
    _inherit = ['sale.order', 'license.check.mixin']
