Setup Instructions

Project Setup

How to setup your project for this example can be found here.

Dialogflow Agent Setup

Build an agent by following the instructions here.

Cloud Storage Setup

Upload the entities.json file to a bucket by following the instructions here.

Cloud Functions Setup

This implementation is deployed on GCP using Cloud Functions. More info here.

To run the Python scripts on GCP, the gcloud command-line tool from the Google Cloud SDK is needed. Refer to the installation page for the appropriate instructions depending on your platform.

Note that this project has been tested on a Unix-based environment.

After installing, make sure to initialize your Cloud project:

`$ gcloud init`

Usage

Create entities one by one

Use the EntityTypesClient.create_entity_type to create entities one by one.

Example

Run the sample using gcloud util as followed:

      $ gcloud functions call entities_builder --data '{
          "entities": [{
             "display_name":
                 "saving-account-types",
             "kind": "KIND_MAP",
             "entities": [{
                 "value": "saving-account-types",

Examples

Using entity_type_batch_uri

The URI to a Google Cloud Storage file containing entity types to update or create. The URI must start with "gs://". The entities.json file is an example of a json format file that can be uploaded to gcs and passed to the function.

    $ gcloud functions call entities_builder --data '{ "bucket": "gs://<bucket_name>/entities.json"}'
Using entity_type_batch_inline

For each entity type in the batch:

  • The name is the the unique identifier of the entity type
  • If name is specified, we update an existing entity type.
  • If name is not specified, we create a new entity type.
   $ gcloud functions call entities_builder --data '{
       "entities_batch": {
           "entity_types":[
               {
                   "name": "5201cee0-ddfb-4f7c-ae94-fff87189d13c",
