# sartography/cr-connect-workflow [![Build Status](https://travis-ci.com/sartography/cr-connect-workflow.svg?branch=master)](https://travis-ci.com/sartography/cr-connect-workflow) # CR Connect Workflow Microservice ## Development Setup ### Tools These instructions assume you're using these development and tools: - IDE: PyCharm Professional Edition - Operating System: Ubuntu ### Environment Setup Make sure all of the following are properly installed on your system: 1. `python3` & `pip3`: - [Install python3 & pip3](https://www.digitalocean.com/community/tutorials/how-to-install-python-3-and-set-up-a-programming-environment-on-an-ubuntu-18-04-server) - [Installing Python 3 on Linux](https://docs.python-guide.org/starting/install3/linux/) 2. `pipenv`: - [Install pipenv](https://pipenv-es.readthedocs.io/es/stable/) - [Add ${HOME}/.local/bin to your PATH](https://github.com/pypa/pipenv/issues/2122#issue-319600584) ### Project Initialization 1. Clone this repository. 2. In PyCharm: - Go to `File > New Project...` - Click `Pure Python` (NOT `Flask`!!) - Click the folder icon in the `Location` field. - Select the directory where you cloned this repository and click `Ok`. - Expand the `Project Interpreter` section. - Select the `New environment using` radio button and choose `Pipenv` in the dropdown. - Under `Base interpreter`, select `Python 3.7` - In the `Pipenv executable` field, enter `/home/your_username_goes_here/.local/bin/pipenv` - Click `Create` ![Project Interpreter](readme_images/new_project.png) 3. PyCharm should automatically install the necessary packages via `pipenv`. For me, the project interpreter did not set set up for me correctly on first attempt. I had to go to File -> Settings -> Project Interpreter and again set the project to use the correct PipEnv environment. Be sure that your settings like simliar to this, or attempt to add the interpreter again by clicking on the gear icon. ![Project Interpreter Settings screen](readme_images/settings.png) 4. With this properly setup for the project, you can now right click on the run.py and set up a new run configuration and set up a run configuration that looks like the following (be sure to save this run configuration so it doesn't go away.) : ![Run Configuration Screenshot](readme_images/run_config.png) ### Running the Web API Just click the "Play" button next to RUN in the top right corner of the screen. The Swagger based view of the API will be avialable at http://0.0.0.0:5000/v1.0/ui/ ### Running Tests We use pytest to execute tests. You can run this from the command line with: ``` pipenv run coverage run -m pytest ``` To run the tests within PyCharm set up a run configuration using pytest (Go to Run, configurations, click the plus icon, select Python Tests, and under this select pytest, defaults should work good-a-plenty with no additional edits required.) ## Documentation Additional Documentation is available on [ReadTheDocs](https://cr-connect-workflow.readthedocs.io/en/latest/#) ### Additional Reading 1. [BPMN](https://www.process.st/bpmn-tutorial/) Is the tool we are using to create diagrams of our business processes. It's is a beautiful concise diagramming tool. We strongly recommend you read this complete tutorial, as this notation is the foundation on which this project as well as many other software systems for businesses are built. Know it well. ### Notes on Creating Good BPMN Diagrams in Comunda 1. Be sure to give each task a thoughtful (but unique!) id. This will make the command line and debugging far far easier. I've tended to pre-fix these, so task_ask_riddle if a task is asking a riddle for instance.
