<div class =“post-text”itemprop =“text”>        谢谢@ alex-blex的小费！           为新集合使用验证器：        > db.createCollection(“places”, {validator: {“geometry.type”: {$in: … [“Point”, “MultiPoint”, “LineString”, “MultiLineString”, “Polygon”, “MultiPolygon”] … }}}) { “ok” : 1 } > db.places.createIndex({‘geometry’: ‘2dsphere’}) { “createdCollectionAutomatically” : false, “numIndexesBefore” : 1, “numIndexesAfter” : 2, “ok” : 1 }
<pre><code></code>
</code></pre>        现在我们无法插入空几何：        > db.places.insert({‘geometry’: []}) WriteResult({ “nInserted” : 0, “writeError” : { “code” : 121, “errmsg” : “Document failed validation” } }) > db.places.insert({‘geometry’: {}}) WriteResult({ “nInserted” : 0, “writeError” : { “code” : 121, “errmsg” : “Document failed validation” } }) > db.places.insert({‘geometry’: null}) WriteResult({ “nInserted” : 0, “writeError” : { “code” : 121, “errmsg” : “Document failed validation” } })
<pre><code></code>
</code></pre>        要将验证器添加到现有集合：        > db.places.createIndex({‘geometry’: ‘2dsphere’}) { “createdCollectionAutomatically” : true, “numIndexesBefore” : 1, “numIndexesAfter” : 2, “ok” : 1 } > db.runCommand({ collMod: ‘places’, validator: {“geometry.type”: {$in: … [“Point”, “MultiPoint”, “LineString”, “MultiLineString”, “Polygon”, “MultiPolygon”] … }}}) { “ok” : 1 }
<pre><code></code>
</code></pre>
