我正在使用Tornado和pydocumentDB在Azure上运行存储应用程序。我也有一个存储过程:
<html>
我想要做的是每次生成新用户并将其文档添加到集合中时,都会增加user_ids文档的function userIDSproc() {
var collection = getContext().getCollection();
// Query documents and take 1st item.
var isAccepted = collection.queryDocuments(
collection.getSelfLink(),
"SELECT * FROM root r WHERE r.id='user_ids_counter'",
function (err, feed, options) {
if (err) throw err;
// Check the feed and if empty, set the body to 'no docs found',
// else take 1st element from feed
if (!feed || !feed.length) getContext().getResponse().setBody('no docs found');
else tryUpdate(feed[0])
});
if (!isAccepted) throw new Error('The query was not accepted by the server.');
function tryUpdate(document){
document.counter += 1;
getContext().getResponse().setBody(document['counter']);
var isAccepted = collection.replaceDocument(document._self, document, function (err, document, options) {
if (err) throw err;
// If we have successfully updated the document - return it in the response body.
getContext().getResponse().setBody(document);
});
}
属性。是否可以调用Sproc,更新计数器,然后查询新计数器的文档,然后使用新计数器作为新用户的ID? GitHub上的documentDB SDK显示了一些方法,如counter
和QueryStoredProcedures(self, collection_link, query, options=None):
,但没有实际执行。
答案 0 :(得分:0)
对于DocumentDB Python SDK,您可以调用ExecuteStoredProcedure(self, sproc_link, params, options=None)
。
您可以在SDK的单元测试中找到一个简短示例:
