Accessing request in TabularInline's clean method

I tried accessing the current user in my admin’s TabularInline form:

class SomeAdmin(admin.ModelAdmin):
    inlines = [ResourceTabularInline,]
class ResourceTabularInline(TabularInline):
    model = BaseResource
    form = ResourceForm
    def get_formset(self, request, obj=None, **kwargs):
        formset = super().get_formset(request, obj, **kwargs)
        formset.user = request.user
        return formset

class ResourceForm(forms.ModelForm):
    resource  = forms.FileField(widget=CustomImageFile, label="resource")

    class Meta:
        model = BaseResource
        fields = ["resource"]

    def __init__(self, *args, **kwargs):
        self.user = kwargs.pop("user")  ###<- error
        super().__init__(*args, **kwargs)
        self.fields["resource"].widget.form_instance = self

    def clean(self):
        print(self.user) # <- obviously not working

Not sure how to approach this - how can access the user in my ResourceForms clean method?

Sorry for trying it again and spamming the forum - anyone an idea on this?
