# Python Typings For FHIR
The FHIR Types package exports types declared using the [typing](https://docs.python.org/3/library/typing.html) library. This provides type checking support when creating dictionaries of FHIR objects in Python.
## Installation
### Installing from Pypi (recommended)
We recommend you first use a virtual environment and activate it in your shell.
`pip install fhir-types`
### Installing from source
1. Clone this repository
1. Change to the package root directory
1. Run the `pipenv install --dev --deploy` command to create and install in a virtual environment
```bash
% pipenv install --dev --deploy
Creating a virtualenv for this project...
Pipfile: /fhir-types/Pipfile
Using /usr/local/bin/python3 (3.9.7) to create virtualenv...
. . .
```
If you want to install globally run `pip install .`, outside of a virtual environment.
### Verify the installation
Verify the installation with `pipenv run almake test`.
```bash
% pipenv run almake test
python -m black --check .
All done! ✨ 🍰 ✨
702 files would be left unchanged.
python -m isort --check --df .
. . .
```
Or, if you have `make` installed:
```bash
% pipenv run make test
<same output as shown above>
```
## Usage
This project was developed using [mypy](https://github.com/python/mypy) for type checking.
### Example
Consider these two FHIR JSON dictionaries.
```python
# myfile.py
from fhir_types import FHIR_Patient
# This is a valid patient dictionary
patient: FHIR_Patient = {
"resourceType": "Patient",
"gender": "female",
"name": [
{
"use": "official",
"family": "Johnson",
"given": ["Jennifer"],
"prefix": ["Mrs."],
}
]
}
# This is an invalid patient dictionary
invalid_patient: FHIR_Patient = {
"resourceType": "PPPPatient", # error 1
"gender": "female123", # error 2
"name": [
{
"123use": "official", # error 3
"family": "Johnson",
"given": ["Jennifer"],
"prefix": ["Mrs."],
}
]
}
```
After installing `mypy` with `pip`, running `mypy myfile.py` will display the errors in the second (invalid) structure.
It is good practice to set up your IDE (such as VS Code) to use `mypy` for linting as you work.
## Issues
The Types located in the fhir_types directory are generated from the official `fhir.schema.json` provided by FHIR.
This data stucture is quite large with and contains cyclical relationships. Unfortunately, `mypy` does not handle cyclical relationships and has an open issue [here](https://github.com/python/mypy/issues/731). We added a workaround that reduces the type checking capabilities for certain properties in some classes.
All properties that point to any of the following classes are given an [Any](https://mypy.readthedocs.io/en/stable/kinds_of_types.html#the-any-type) type because these lead to circular references. These were found by repeatedly running the `mypy` command.
```bash
CIRCULAR_REFERENCES = {
"Extension",
"Identifier",
"ResourceList",
"QuestionnaireResponse_Answer",
"GraphDefinition_Link",
"ExampleScenario_Process",
"ExampleScenario_Alternative",
}
```
The other case is when a property points back to a parent class.
```python
from fhir_types import FHIR_Questionnaire_Item
FHIR_Questionnaire_Item = TypedDict("FHIR_Questionnaire_Item", {
"id": "123",
item: List[Any] # This used to be FHIR_Questionnaire_Item but was changed to Any
})
```
Here, full type checking can be accomplished by creating two separate dictionaries and then combining them. For example:
```python
from fhir_types import FHIR_Extension, FHIR_Patient
extension: FHIR_Extension = {
"valueAddress": {
"city": "Springfield",
"state": "Massachusetts",
"country": "US"
}
}
patient: FHIR_Patient = {
"gender": "male",
"extension": [extension]
}
```
