Solve the following python programming problem given the following code:
@ property 
def data(self) : 
    def render(f) : 
        title = { 
            'public' : _ ('Public Facility'), 
            'private' : _ ('Private Facility'), 
            'transport' : _ ('Transport'), 
} [f.fields_without_attributes ['type']] 
        return format_html (('%s: %s<br /># %s' % (title, f.fields_without_attributes.get ('name', ''), f.fields_without_attributes.get ('number', '')))) 
fixtures = FixtureDataItem.by_group (self.group) 
    _data = [] 
    self._headers = [] 
    for f in fixtures : 
        _data.append (render (fixtures)) 
        self._headers.append (' ') 
if (not _data) : 
        _data = [('No referrals for %s' % self.group.name)] 
        self._headers = [' '] 
return _data 

    
    

    Fix the buggy line: _data.append (render (fixtures))
assistant
#Here is Python program to fix the buggy line: _data.

_data.append (render (f))
