Not able to run Dtale on root url about dtale HOT 10 CLOSED

So app_root is something that is meant to be used when serving D-Tale up within jupyerhub. There is a server proxy that opens up all flask routes using a different URL path.

I can try seeing if I can make use of Flask's url_prefix parameter, but honestly your best bet is to do something like using different ports (i think you just need to open both ports in your docker configuration):

import dtale
import pandas as pd
d = dtale.show(pd.DataFrame([1,2,3,4,5]),host='localhost', port="40000")
d._main_url

d1 = dtale.show(pd.DataFrame([1,2,3,4,5]),host='localhost', port="40001")
d1._main_url

Or you can apply names to your data:

import dtale
import pandas as pd
d = dtale.show(pd.DataFrame([1,2,3,4,5]),host='localhost', name="satya")
d._main_url  # http://localhost:40000/dtale/main/satya

d1 = dtale.show(pd.DataFrame([1,2,3,4,5]),host='localhost', name="test", ignore_duplicate=True)
d1._main_url  # http://localhost:40000/dtale/main/test

from dtale.

Thanks for the suggestion @aschonfeld its really helpfull, I tried giving names to data and its working good. But i getting some Bad request
errors in my jupyter notebook continuously, however I am able to access the Dtale with the urls below.
http://localhost:40000/dtale/main/satya
http://localhost:40000/dtale/main/test

Is there any way we can do this without errors ?

from dtale.

Are you hitting the D-Tale URLs from https? I've never seen that error and the only thing I can find about it is when someone tries to hit a flask endpoint from https that is only setup for http: https://stackoverflow.com/questions/58902838/python-flask-error-code-400-message-bad-request-version

from dtale.

@aschonfeld I getting the error as soon as I run the second cell attached in the above screenshot. I am accessing it on http.

from dtale.

So I was able to run your code in a jupyter notebook with no issue. Is your notebook running under HTTPS?

from dtale.

@aschonfeld Yes, Its running inside Kubenertes clusters and exposed using ingress on Https

from dtale.

ok then thats the problem. Do you have to use HTTPS?

from dtale.

@aschonfeld Yes, We need to run our service on https only

from dtale.

So what I plan on doing is exposing the ability to specify an ssl_context when starting up the flask process invoked by dtale.show. This way you can call something like dtale.show(..., ssl_context="adhoc") and it should allow you to use HTTPS.

I'll keep you posted about when this change gets released

from dtale.

@go-kool @nandinibalusu978 just released v3.6.0 to pypi (should be on conda-forge soon) with this fix included.

Also, if you haven't already, please put your ⭐ on the repo when you get a sec. Thanks! 🙏
