Django Grappelli usergroup conditional dashboard

Question

Working with Grappelli(2.11.1) in Django(1.11.10). I crafted small custom dashboard and look now for some method to variate appearance of elements. In particular I need to show some url-element

self.children.append(modules.LinkList(
    _('e-mail'),
    column=2,
    css_class=('grp-collapse grp-closed'),
    children=[
        {
            'title': _('gmail'),
            'url': 'gmail.com',
            'external': True,
        },
    ]
))

only to users of specified group and to hide it to others. In regular way I would try to use auth.get_user(), but this depends on 'request'. Which is not available, or at least visible, for me. Any way to make this feature? Thanks anyway.

One possible workaround for this (though there are almost certainly better ways):

First, add 'django.template.context_processors.request' to settings.TEMPLATES['OPTIONS']['context_processors'] if it isn't there already. That'll add requests to the template context.

Next, do your changes to the custom dashboard within the init_with_context method, where you now have access to the request (and therefore request.user)

from grappelli.dashboard import modules, Dashboard

class CustomDashboard(Dashboard):

    def init_with_context(self, context):
      request = context['request']
      user = request.user
      groups = user.groups.all()
      if groups == "whatever condition you want":
        self.children.append(
            ...
        )
