A Word-Trend Business Intelligence Dashboard That Provides Actionable Business Insights.
Business owners don’t have time to decode what people are saying about their business online - they just want to know what to improve - so our goal for Tally AI was to provide actionable suggestions to help businesses grow profit.
The app is currently piloting its functionality on hundreds of cafes and restaurants around the Phoenix, AZ area.
Tally is a one-stop snapshot for understanding your businesses' Yelp reviews.
"Data analytics is not just for big corporations.
Your small business can stay on top of an ever changing marketplace
with the power of Tally."

I might look into training my staff on customer service etiquette
since people are complaining about the service.
I'm relieved that my half-price bottle service is getting
buzz from the word trend chart.
Seeing a snapshot of trending phrases from my competitors
have made me realize that I might think about introducing happy hour.

【Local Environment】
Add system environment variables in the Python virtual environment (NO quotation marks).
You can add a .env file in the django-tally folder, then add the following lines to the file (replace * with your credentials). Every time when you start the virtual environment, those variables will be set automatically. (Please make sure that in the .gitignore file .env has been added, or you are exposing the credentials to the Internet.)
RDS_DB_NAME=*
RDS_USERNAME=*
RDS_PASSWORD=*
RDS_HOSTNAME=*
RDS_PORT=*
【Manually】
Or you can manually add it every time after you start the virtual environment.
For Windows Powershell, use set VARNAME=value.
For MacOS/Linux use export VARNAME=value.

Setting up URL patterns
E.g. regular expression match UUID as primary key (?P<pk>[0-9a-f-]+):
urlpatterns = {
url(r'^yelp/$',
YelpYelpScrapingCreateView.as_view(), name="create"),
url(r'^yelp/(?P<pk>[0-9a-f-]+)/$',
YelpYelpScrapingDetailsView.as_view(), name="details"),
}
E.g. query strings
urlpatterns = {path('<slug:business_id>', home, name='home')}
def home(request, business_id):
viztype = request.GET.get('viztype')
if viztype == '1':
result = json.dumps(yelpTrendyPhrases(business_id))
elif viztype == '2':
result = json.dumps(yelpReviewCountMonthly(business_id))
else:
result = json.dumps(getDataViztype0(business_id))

Follow this tutorial to build a REST API.
$ python manage.py inspectdb > models.py
After running this command, modify class names in the models.py file.
Add to every class name. E.g.
For app "example", change class Bucketlist -> class ExampleBucketlist
For app "yelp", change class Business -> class YelpBusiness
Follow the instructions in the models.py file, make sure model definitions are correct.
Then move the models.py file to the corresponding app folder.
So every app would have their own models without conflicting with other apps.
This is an example of the Django data models created.
https://github.com/Nov05/django-tally/blob/master/example/models.py
You can query with or without Django data models. E.g.
https://github.com/Nov05/django-tally/blob/master/tallylib/sql.py
【Debug】
Issue: Django “ValueError: source code string cannot contain null bytes”
Solution: You can simply create a new .py file, copy and paste the models.py content to it, then replace the models.py file with it.
spaCy models
https://spacy.io/usage/models
How to install models
https://pypi.org/project/spacy/
Download spaCy model manually (Not in use)
https://github.com/explosion/spacy-models/releases
You can install spaCy models just like installing a Python package.
pipenv install https://github.com/explosion/spacy-models/releases/download/en_core_web_sm-2.2.5/en_core_web_sm-2.2.5.tar.gz
Then import the models in your code.
import en_core_web_sm
nlp = en_core_web_sm.load()
or
import spacy
nlp = spacy.load("en_core_web_sm")
【Deployment】
Make sure the following 2 lines are in the requirements.txt.
spacy>=2.0.0,<3.0.0
https://github.com/explosion/spacy-models/releases/download/en_core_web_sm-2.2.5/en_core_web_sm-2.2.5.tar.gz
Make sure remove spacy==2.2.3and en_core_web_sm==2.25 from the file, or you will get an error when delpoying saying "Could not find a version that satisfies the requirement en-core-web-sm==2.2.5".
【Manually】
Put the following folder in the repo (same level with manage.py).
spacy.load("en_core_web_sm/en_core_web_sm-2.2.5") with __init__.py
CAUTION: You can do it this way, but deployment from Windows 10 to AWS Elastica Beanstalk might have UnicodeDecodeError when loading a model, while both launching server on Windows 10 locally or deployment from MacOS seem fine.
