said 'a cursor returns returns', and 'fetch' can be used to return all mailing documents I did not, but I did not find the full context of this cursor object.
I want to check this cursor object to successfully find some results or nothing.
The following is what I am doing:
if (tag.find ({name: tag ["tag"]}). Fetch (). Length === 0) {// Not Found, Add Default Document}
To ensure that this is the best (practiced) method?
idiom usage:
if (! TagFindOn (. ..)) {// nothing found, add default document}
It is more efficient fetch ()
because it only databases for a document Asks.
You can also use it, but be careful.
