如何使用couchdb-python来调用带有键列表的视图？

Question

我有ViewDefinition：

""" Models id."""
models = ViewDefinition('models', 'by_authors', """
function(doc) {
  if (doc.type == "definition") {
    for (var i = 0; i < doc.authors.length; i++) {
      var author = doc.authors[i];
      emit(author, doc._id);
    }
  }
}""")

我这样称呼它：

models = []
for principal in principals:
    models += [d.value for d in views.models(self._db)[principal].rows]
return list(set(models))

如何申请密钥列表并将其称为：

models = [d.value for d in views.models(self._db)[*principals].rows]

Answer 1

解决方案很简单，我也必须阅读源代码才能找到它。

models = [d.value for d in views.models(self._db, keys=principals).rows]
