Using the StackedInline to link two models is straight forward and a much clean practice, so basically this is my solution below:
class ContentInlineAdmin(admin.StackedInline):
model = Content
@admin.register(SchoolProfile)
class SchoolProfileAdmin(admin.ModelAdmin):
list_display = ('school_name',)
inlines = [ContentInlineAdmin]
