time-tracker-api

The API of the TSheets killer app.

Getting started

Follow the following instructions to get the project ready to use ASAP.

Requirements

Be sure you have installed in your system

• Python version 3 in your path. It will install automatically pip as well.
• A virtual environment, namely venv.

Setup

• Create and activate the environment,

  In Windows:

  python -m venv .venv
  .venv\Scripts\activate.bat
  

  In Unix based operative systems:

  virtualenv .venv
  source .venv/bin/activate
  

• Install the requirements:

  python3 -m pip install -r requirements/<stage>.txt
  

  The stage can be dev or prod. Remember to do it with Python 3.

• Install the Microsoft ODBC Driver for SQL Server in your operative system. Then you have to check out what is the name of the SQL Driver installation. Check it out with:

vim /usr/local/etc/odbcinst.ini

It may display something like

[ODBC Driver 17 for SQL Server] 
Description=Microsoft ODBC Driver 17 for SQL Server 
Driver=/usr/local/lib/libmsodbcsql.17.dylib 
UsageCount=2

Then specify the driver name, in this case DBC Driver 17 for SQL Server in the DATABASE_URI, e.g.:

DATABASE_URI=mssql+pyodbc://<user>:<password>@time-tracker-srv.database.windows.net/<database>?driver\=ODBC Driver 17 for SQL Server

To troubleshoot issues regarding this part please check out:

• Install the Microsoft ODBC driver for SQL Server (macOS).
• Github issue odbcinst: SQLRemoveDriver failed with Unable to find component name.
• Stack overflow solution to Can't open lib 'ODBC Driver 13 for SQL Server'? Sym linking issue?.

How to use it

• Set the env var FLASK_APP to time_tracker_api and start the app:

  In Windows

  set FLASK_APP=time_tracker_api
  flask run
  

  In Unix based operative systems:

  export FLASK_APP=time_tracker_api
  flask run
  

• Open http://127.0.0.1:5000/ in a browser. You will find in the presented UI a link to the swagger.json with the definition of the api.

Development

Test

We are using Pytest](https://docs.pytest.org/en/latest/index.html) for tests. The tests are located in the package tests and use the conventions for python test discovery.

To run the tests just execute:

python3 -m pytest -v

The option -v shows which tests failed or succeeded. Have into account that you can also debug each test (test_* files) with the help of an IDE like PyCharm.

Coverage

To check the coverage of the tests execute

 coverage run -m pytest -v

To get a report table

 coverage report

To get a full report in html

 coverage html

Then check in the htmlcov/index.html to see it

If you want that previously collected coverage data is erased, you can execute:

coverage erase

CLI

There are available commands, aware of the API, that can be very helpful to you. You can check them out by running

python cli.py

If you want to run an specific command, e.g. gen_swagger_json, specify it as a param as well as its correspondent options.

python cli.py gen_swagger_json -f ~/Downloads/swagger.json

Built with

• Python version 3 as backend programming language. Strong typing for the win.
• Flask as the micro framework of choice.
• Flask RestPlus for building Restful APIs with Swagger.
• Pytest for tests
• Coverage for coverage
• Swagger for documentation and standardization, taking into account the API import restrictions and known issues in Azure.
