Solve the following python programming problem given the following code:
@ permission_required ('services.manage_aliases') 
def alias_edit(request, id, template_name = 'membership/entity_edit.html') : 
    alias = get_object_or_404 (Alias, id = id) 
    class Form (ModelForm) : 
        class Meta () : 
            model = Alias 
            fields = '__all__' 
owner = ModelChoiceField (queryset = Membership.objects.filter (pk = alias.owner.id), empty_label = None) 
        @ staticmethod 
        def clean_name() : 
            return alias.name 
@ staticmethod 
        def clean_owner() : 
            return alias.owner 
def disable_fields(self) : 
            self.fields ['name'].required = False 
            self.fields ['name'].widget.attrs ['readonly'] = 'readonly' 
            self.fields ['owner'].required = False 
            self.fields ['owner'].widget.attrs ['readonly'] = 'readonly' 
if (request.method == 'POST') : 
        form = Form (request.POST, instance = alias) 
        before = model_to_dict (alias) 
        form.disable_fields () 
        if form.is_valid () : 
            form.save () 
            after = model_to_dict (alias) 
            log_change (alias, request.user, before, after) 
            return redirect ('alias_edit', id) 
else : 
        form = Form (instance = after) 
        form.disable_fields () 
logentries = bake_log_entries (alias.logs.all ()) 
    return render_to_response (template_name, { 
        'form' : form, 
        'alias' : alias, 
        'logentries' : logentries, 
}, context_instance = RequestContext (request)) 

    
    

    Fix the buggy line: form = Form (instance = after)

#Here is Python program to fix the buggy line: form = Form (instance = after)

form = Form (instance = alias)
