# datamodelutils

Wrapper utils to allow gen3datamodel.models to be loaded after initialization.

For example

```
from datamodelutils import models
from dictionaryutils import DataDictionary, dictionary

d = DataDictionary(url="https://s3.amazonaws.com/dictionary-artifacts/bhcdictionary/feat/s3/schema.json")

dictionary.init(d)
# Always import gen3datamodel after dictionary has been initialized.
# Creates a singleton for life of python session.
# Required for backward compatibility. 
from gen3datamodel import models as md
models.init(md)

print(models)
```

will produce output of

```
<module 'gen3datamodel.models' from '/Users/phillis/Documents/work/datamodelutils/venv/lib/python3.9/site-packages/gen3datamodel/gen3datamodel/models/__init__.py'>
```
