Update data with a FieldMask

When updating agent data with the API, you can choose to overwrite the entire data type or to overwrite only specific fields of the data type. It is usually best to overwrite specific fields, so you avoid accidentally overwriting all of your data. To overwrite specific fields, supply a FieldMask to your update request.

The following examples show how to supply a FieldMask to update the display name for an Intents type.

REST

Supply the updateMask URL query parameter for the patch method. For example: 

 ?updateMask=displayName

Node.js

const {IntentsClient} = require('@google-cloud/dialogflow'); const intentClient = new IntentsClient(); const agentPath = intentClient.projectAgentPath(projectId); const intentPath = agentPath + '/intents/' + intentId; const intent = await intentClient.getIntent({name: intentPath}); intent[0].displayName = displayName; const updateMask = {  paths: ['display_name'], }; const updateIntentRequest = {  intent: intent[0],  updateMask: updateMask,  languageCode: 'en', }; //Send the request for update the intent. const result = await intentClient.updateIntent(updateIntentRequest); console.log(result);

Python
