Add the Watson service
You now have your shell application and can add the Watson service.
-
- In Bluemix, add or bind the Watson Language Translation service. You don’t need to restart the application for now.
Now, you see the service credentials.
- In Bluemix, add or bind the Watson Language Translation service. You don’t need to restart the application for now.
-
- In the wl.py file, import the language translation component from the watson_developer_cloud SDK:
# -*- coding: utf-8 -*-
from django.shortcuts import render
from django import forms
from watson_developer_cloud import LanguageTranslationV2 as LanguageTranslation
from watson_developer_cloud import WatsonException
import logging
import json
The final change is in the placeholder that you created in the wl.py file. Remember to use the service credentials that you got for Bluemix as the language translation user name and password.
- In the wl.py file, import the language translation component from the watson_developer_cloud SDK:
-
- Open the wl.ph file and find this code:
if form.is_valid():
data = form.cleaned_data['txtdata']
logger.info("Text to be processed is %s " % data)
lang = "TBD"
allinfo['lang'] = lang
- Open the wl.ph file and find this code:
- Add code that invokes the language detection service after the line
lang = “TBD”
and before the lineallinfo[‘lang’] = lang:
lang = "TBD"
[Add code here]
allinfo['lang'] = lang
if form.is_valid():
data = form.cleaned_data['txtdata']
