Solve the following python programming problem given the following code:
@ register.to_end_tag 
def editable(parsed, context, token) : 
    '
    Add the required HTML to the parsed content for in-line editing,
    such as the icon and edit form if the object is deemed to be
    editable - either it has an ``editable`` method which returns
    ``True``, or the logged in user has change permissions for the
    model.
    ' 
    def parse_field(field) : 
        field = field.split ('.') 
        obj = context.get (field.pop (0), None) 
        attr = field.pop () 
        while field : 
            obj = getattr (obj, field.pop (0)) 
            if callable (obj) : 
                obj = obj () 
return (obj, attr) 
fields = [parse_field (f) for f in token.split_contents () [1 :]] 
    if fields : 
        fields = [f for f in fields if ((len (f) == 2) and (f [0] is fields [0] [0]))] 
if (not parsed.strip ()) : 
        try : 
            parsed = ''.join ([str (getattr (* field)) for field in fields]) 
except AttributeError : 
            pass 
if (settings.INLINE_EDITING_ENABLED and t and ('request' in context)) : 
        obj = fields [0] [0] 
        if (isinstance (obj, Model) and is_editable (obj, context ['request'])) : 
            field_names = ','.join ([f [1] for f in fields]) 
            context ['editable_form'] = get_edit_form (obj, field_names) 
            context ['original'] = parsed 
            t = get_template ('includes/editable_form.html') 
            return t.render (context) 
return parsed
