Different development teams can work with the same data, each needing to know what they can expect to find in a particular collection.Many projects reach a point where it’s necessary to enforce rules on what’s being stored in the database – for example, that for any document in a particular collection, you can be certain that specific attributes are present in every document. For business leaders, the application gets launched much faster, and new features can be rolled out more frequently.

Operations teams appreciate the fact that they don’t need to perform a time-consuming schema upgrade operation every time the developers need to store a different attribute. One of MongoDB’s primary attractions for developers is that it gives them the ability to start application development without first needing to define a formal schema.
This makes it easy to create and modify rules that ensure that all documents written to a collection contain the data you expect to be there. This post looks at a new feature in MongoDB Compass 1.5 (in beta at the time of writing) which allows document validation rules to be added from the GUI rather from the mongo shell command line. Adding Document Validation Rules Using MongoDB Compass 1.5 Println ( "UpdateMany() result UpsertedID:", result. Exit ( 1 ) // Exit the script on errorįmt. Println ( "UpdateMany() result ERROR:", err ) Check for error, else print the UpdateMany() API call resultsįmt. Call the driver's UpdateMany() method and pass filter and update to it Create a nested BSON document for the documents' fields that are updated "$eq": true, // check if bool field has value of 'true' Declare a filter to pass to the UpdateMany() methodįilter := bson.
Access a MongoDB collection through a databaseĬol := client. Println ( "mongo.Connect() ERROR:", err )

How to use MongoDB Compass UI to verify that documents were updated using UpdateMany() in Golang To update documents with Mongo-Go-driver the API call must be executed in a Golang script using the. Remember, to update MongoDB documents there must be at least one document in a MongoDB collection with data fields that can be updated. Finally, the article explained how to check for errors and parse the MongoDB Golang driver’s API results object. Specifically, how to declare a new MongoDB collection instance from a database using the Golang driver, create a MongoDB query filter for the Golang API calls, how to declare a nested BSON object for the MongoDB update fields and create a Golang BSON object that will update multiple fields. This tutorial covered how to update MongoDB documents with the Golang driver. The result object’s attributes should have several integer value attributes representing the documents that matched the filter, the documents that were modified and information about any upserted MongoDB documents in the process of the API call. Println ( "UpdateMany() result UpsertedCount:", result. Println ( "UpdateMany() result ModifiedCount:", result. Println ( "UpdateMany() result MatchedCount:", result. Println ( "UpdateMany() result TYPE:", reflect. Println ( "UpdateMany() result:", result )įmt.
