## Setup
### Connection strings
Create a `secrets.json` in the root of this repo with the following structure (values to be replaces by desired config):
```json
{
"postgres": {
"username": "postgres",
"password": "postgres",
"host": "localhost",
"database": "postgres",
"port": 5432
},
"mongo": {
"username": "username",
"password": "password",
"host": "localhost",
"database": "transparenzregister",
"port": 27017
}
}
```
Example usage see [connector.py](./src/aki_prj23_transparenzregister/utils/postgres/connector.py)
## Code style
We defined to use the following formats:
- Whitespace Formatting by [Black](https://github.com/psf/black)
- Docstrings Style see the examples provided
by [sphinx napoleon](https://sphinxcontrib-napoleon.readthedocs.io/en/latest/example_google.html) Types in the
docstrings are optional but should be consistent per module.
- Import Order by [isort](https://pycqa.github.io/isort/)
- Strict Typing of function headers see the examples provided by
the [mypy](https://mypy.readthedocs.io/en/stable/cheat_sheet_py3.html) documentation.
## Language
We decided to use english on everything close to code but will write longer texts that are not close to the code in
german.
## Pre-Commit Usage
- the following code format rules are so enforced:
- Whitespace formatting:
- Python-[Black](https://github.com/psf/black)
- leading whitespace in all files
- Auto format: yaml, toml, ini
- Import norm by:
- [isort](https://pycqa.github.io/isort/)
- absolut module path
- Validation:
- yaml, toml, json, xml
- Secret detection
- python norms ([pep8](https://peps.python.org/pep-0008/))
with [ruff](https://github.com/astral-sh/ruff)
- type checking with ([mypy](https://github.com/python/mypy))
