Hey Todd, I really want to buy you coffee but please show an example with callback functions like you introduce in the tutorial but don't really get in depth.
I posted a question on stackoverflow about this: https://stackoverflow.com/questions/64151018/plotly-dash-embedded-in-flask-cannot-get-callbacks-to-work

So does this mean you could use the regular flask decorators, emit, and listen functions?

Just ran across the tutorial page, which looks pretty great and is just what I'm wanting to do.

However, I couldn't help but notice that the code-snippet at "keep an eye on what changes" uses create_dashboard ... whereas immediately afterward, all the code blocks use init_dashboard.

In context that surely is just a simple edit/typo, but it's probably worth fixing, lest somebody get confused....

Hi, I think you may miss numpy package in the data.py file.

Hey and thanks for your awesome tutorial.
I am trying to use this to add a layer of authenticaion over my dash app, which I hoped I could do by adding a decorator to the route for the dash. but even when hacking dash like this I don't understand how I could do that?

Hi, your tutorial is very good! I have a question. Let's say I want to build a view for showing data and it's a different view than the dashboard (/dashapp/) - let's say it goes to /dashapp/summary. How do I do this?

How do you config a procfile to run on heroku with the current project configuration?

Hi Todd,
Thanks for the great article. Under poetry shell on Window 10, when I issued poetry run command, I got the message below.

>poetry run
Traceback (most recent call last): File "<string>", line 1, in <module> TypeError: __call__() missing 2 required positional arguments: 'environ' and 'start_response'

Thanks in advance,
Ibrahim

Hi Todd! Thank you very much for this amazing tutorial - this is great.

I'm trying to get it up and running and getting this error:

UPDATE: removed import ddtrace and patch_all() - now it is working :)

Thank you for a really awesome tutorial!

I'd like to package this as an application using pyinstaller. The straightforward approach doesn't seem to work (perhaps because of the directory structure), have you had any experience with this?

I've been trying to figure this out for a dash project I've been working on and came across your tutorial. I've been looking through the code to find how you did the layover when hovering over the tables, but can't find it. Any way you could point me to the place where the logic for this is at? Thanks.

Hi Todd,

Thank you for the amazing tutorial!!

Wanted to ask - how would it be possible to change the port being served from 5000? i.e. when deploying an app like this, so that user doesn't have to go to website.com:5000/dashapp/ but just serve it on one of the default ports?

Thank you!

There is an error with this repository's Renovate configuration that needs to be fixed. As a precaution, Renovate will stop PRs until it is resolved.

Error type: undefined. Note: this is a nested preset so please contact the preset author if you are unable to fix it yourself.

First thanks for the tutorial.

I'm wondering if you could help me how to secure the /dashapp using @login_required decorator from flask-login.

Best Regards.
Kleyson Rios.
