proposta de simplificação de rota para todos os recursos restrito ao verbo GET. Será necessário fazer ajustes

resources = ['users', 'companies', 'condominiums', 'employees', 'elections', 'meetings']

return jsonify({'error': 'Recurso não encontrado'}), 404

collection = db[resource]
docs = [doc for doc in collection.find()]
return json.dumps(docs, default=json_util.default)
