extra_template_data not working

[FlorianLudwig]

Describe the bug

custom_template_dir seems to be ignored:

datamodel_code_generator.generate(custom_template_dir="some/path")

Version:

• datamodel-code-generator Version: git master

Interesting.
It works fine for a simple unittest.
Did you give me some hints? Would you show me custom_template?

[FlorianLudwig]

Here a simple way to reproduce this by replacing the BaseModel.jinja2 without having any effect:

mkdir -p template/pydantic
echo "nope" > template/pydantic/BaseModel.jinja2
datamodel-codegen --input datamodel-code-generator/tests/data/openapi/api.yaml --input-file-type openapi --output gen.py --custom-template-dir template
grep nope gen.py

The example I am working with is this one: https://github.com/FlorianLudwig/pdk8s/tree/7e2479ccb1f25c7173368cb0fef2aef7f4501ae9/pdk8s/template

My build process includes copying this folder inside datamodel-code-generator.

I have understood why the case does not affect results.

$ mkdir -p template/pydantic
$ echo "nope" > template/pydantic/BaseModel.jinja2
$ datamodel-codegen --input tests/data/openapi/api.yaml --input-file-type openapi --output gen.py --custom-template-dir template/pydantic
$ grep nope gen.py  |wc -l

We should specify a nested directory.
But, It may not be correct.
We can't use a custom template for Enum.

[FlorianLudwig]

oh. okay. I misunderstood how it works then. So not a bug. Closing.

Thanks!

@FlorianLudwig
We should explain the feature in documents.
I have created an issue to add a document for a custom template.
