Retail API - Python Client Lib Sample - anyone

[C G]

Hi all,

I am struggling with the Python client library: is anyone able to share a short sample snippet, e.g. create a product via Retail AI? 

Thanks in advance,

christian

There are some basic examples if you view the pydocs, for example:

pydoc3 google.cloud.retail.ProductServiceClient

Here's a very barebones example using the import method.  create_product would be similar.  Ping me if you have any trouble.


from google.cloud import retail
from google.oauth2 import service_account

SERVICE_ACCOUNT_FILE = 'yourkeyfile.json'
PROJECT_NUM = "####"

SCOPES = ['https://www.googleapis.com/auth/cloud-platform']
credentials = service_account.Credentials.from_service_account_file(
SERVICE_ACCOUNT_FILE, scopes=SCOPES)

client = retail.ProductServiceClient(credentials=credentials)

products = {
  "products": [
    {
      "id": "123",
      "title": "Steamed Hams",
      "description": "Bulk Lot of Steamed Hams",
      "categories": ['Food','Steamed & Canned'],
    }
  ]
}

inputConfig = {"product_inline_source": products}
parent = 'projects/' + PROJECT_NUM + '/locations/global/catalogs/default_catalog/branches/0'

response = client.import_products(parent,inputConfig)

Hi, thanks. That was helpful, product import works.

I tried to import user events in a similar manner, but I am having problems - again - in creating the user event import request. I know this is not directly related to Retail API, but I cannot find any documentation or samples on how to construct the request objects in the Python client libs accordingly:

Here's my (erroneous) snippet:

user_events = {

    "user_events": [

        {

            "event_type": "home-page-view",

            "visitor_id": "visitor-1",

            "event_time": "XXX"  # problem 

        }

    ]

}

import_user_events_request = {

    "parent": 'projects/' + PROJECT_ID + '/locations/global/catalogs/default_catalog/userEvents:import',

    "input_config": {"user_event_inline_source": user_events}

}

response = user_event_service.import_user_events(import_user_events_request)

Problem seems to be the 'event_time' field - supposed to be a (protobuf) timestamp. Can't find any docs on how to create such a timestamp. 

Again, thanks in advance

You can use  google.protobuf.timestamp_pb2.Timestamp:

 

import datetime

from google.protobuf.timestamp_pb2 import Timestamp

...

timestamp = Timestamp()

timestamp.FromDatetime(dt=datetime.datetime.now())

...

Also, your parent string should be something like:

parent = 'projects/' + PROJECT_ID + '/locations/global/catalogs/default_catalog'

Thanks again. I applied you suggestions, I still receive an 'invalid argument' error.

Here is my current snippet:

timestamp = Timestamp()

timestamp.FromDatetime(dt=datetime.datetime.now())

user_events = {

    "user_events": [

        {

            "event_type": "home-page-view",

            "visitor_id": "visitor-1",

            "event_time": timestamp

        }

    ]

}

import_user_events_request = {

    "parent": 'projects/' + PROJECT_ID + '/locations/global/catalogs/default_catalog/branches/0',

    "input_config": {"user_event_inline_source": user_events}

}

response = user_event_service.import_user_events(import_user_events_request)

What am I missing? Is there a way to get more verbose error messages (ie which argument is invalid, which fields are missing)?
Sorry for bothering again, thanks in advance. Any hint appreciated!

Your parent path is still incorrect, the catalog does not have a branch only products have branches specified.

I meant *events* do not have branches, so for event import I believe you should have this as the parent:

parent = 'projects/' + PROJECT_ID + '/locations/global/catalogs/default_catalog'

Note the parent for each method specified in the API docs:
