[英]Having trouble with CouchDB design document and validate_doc_update function
I'm new to CouchDB, and I'm having a lot of trouble with getting my design document to work in my database. 我是CouchDB的新手,并且在使设计文档在数据库中工作时遇到很多麻烦。
This is my design document: 这是我的设计文件:
{
"language": "javascript",
"validate_doc_update": "function(newDoc, oldDoc, userCtx) {
function require(field, message) {
message = message || "Document must have a " + field;
if (!newDoc[field]) throw({forbidden : message});
};
function unchanged(field) {
if (oldDoc && toJSON(oldDoc[field] != toJSON(newDoc[field])) {
}
};
if (newDoc.type == "fortune") {
require("body");
require("sequence_id");
require("created_at");
unchanged("sequence_id");
unchanged("created_at");
}
};",
"views": {
"fortune_count": {
"map": "function(doc) { if(doc.sequence_id && doc.body) { emit(doc.sequence_id, doc.body); }",
"reduce": "_count"
}
},
"shows": {
}
}
Let me break down the problems I'm having: 让我分解一下我遇到的问题:
I'm having trouble sending this to my database as a put request. 我在将其作为放置请求发送到我的数据库时遇到了麻烦。 Apparently this is invalid JSON. 显然,这是无效的JSON。 I'm not an expert at JSON, and this extremely frustrating. 我不是JSON方面的专家,这非常令人沮丧。 Any thoughts? 有什么想法吗?
Because of the problems I was having with the put request, I decided to add my design document using Futon. 由于放置请求存在问题,因此我决定使用Futon添加设计文档。 My database seems to be fine with the view I have here, but when I try to add documents to the database, I get an error saying that my validate_doc_update text doesn't evaluate to a function. 我在这里的视图看来数据库不错,但是当我尝试向数据库中添加文档时,出现一条错误消息,提示我的validate_doc_update文本无法求值。 Any advice on what is wrong with my validate function? 关于我的validate函数有什么问题的任何建议吗?
Because of the difficulty I'm having with my validate function, I tried putting a dumb version in the design doc: 由于我的validate函数遇到困难,因此我尝试在设计文档中放入一个哑版本:
"validate_doc_update": "function(newDoc, oldDoc, userCtx) { if (newDoc.type == "fortune") {} };",
I can create documents with this version in place, but it is not of much use. 我可以使用此版本来创建文档,但是并没有太大用处。
Any help would be appreciated. 任何帮助,将不胜感激。
Thanks, 谢谢,

您只是忘了在(oldDoc && toJSON(oldDoc[field] != toJSON(newDoc[field]))
关闭括号(oldDoc && toJSON(oldDoc[field] != toJSON(newDoc[field]))
