Flask current directory

I want to easily reference same-directory templates from arbitrary locations in a flask app, for example:

.
├── app.py
├── src
│   └── thing
│       ├── __init__.py
│       ├── component.html
│       └── component.py
└── templates

Normally, I would have to render_template referencing the templates directory and go from there, but this is a pain. How can call the same-directory template consistently with a filepath from something like component.py, i.e. something like

in component.py

return render_template(self.this_files_directory + "/component.html", data=data)

How can I do this?

You can reconfigure the default template directory when you instantiate your application object:

from flask import Flask

app = Flask(__name__, template_folder='path/to/templates')

The "Flasky" way to do this, though, would be to use Blueprints to match your directory structure, so within src/thing/__init__.py:

from flask import Blueprint

bp = Blueprint('thing', __name__, template_folder='src/thing')

from . import component  # e.g. your views for the blueprint

Then, within your app.py you import and register each blueprint:

from flask import Flask

app = Flask(__name__)

from src import thing
app.register_blueprint(thing.bp, url_prefix="/thing")

Also, probably very worthwhile to read through this:

http://flask.pocoo.org/docs/0.12/blueprints/#blueprints
