Base title + base description

[xelaxela13]

class MetadataMixin(object):

    def get_meta_title(self, context=None):
        self.title = getattr(settings, 'META_BASE_TITLE', '') + ' ' + self.title
        return self.title

or

class Meta(object):
 
    def __init__(self, **kwargs):
       self.title = settings.META_BASE_TITLE + ' ' + str(self.title) \
            if getattr(settings, 'META_BASE_TITLE', False) else str(self.title)
        self.description = settings.META_BASE_DESCRIPTION + ' ' + str(self.description) \
            if getattr(settings, 'META_BASE_DESCRIPTION', False) else str(self.description)

BASE_TITLE may be site name or something else, for example

As this not fit all the use cases, it can be complex to add to the core.
You can easily implement this in your own classes / mixin
Anyway I will happily review patches that implement this, if there is enough consensus

Tell me please, in what a branch can I do a Pull request? In "develop" I can`t, fatal: unable to access

You have forked the repo, pushed the change in your fork and when you try to open a PR from your repo to this you get that error?
