Ask any question about QuantStack projects: xtensor, xeus, voila, Jupyter widgets, mamba
maybe showing links instead of a button is what would be less surprising for the user?
Thanks all. A colleague told me it runs on his side. It is very erratic, i.e. I still can not manage to make it work. Since I am working in jupyterHub I was wondering if this is a server-side thing or a client side thing. I will check out chrome options. and here it is:
Indeed I had to change that option.
what makes me think I have to think about other option (client side) since now I am going to get pop ups from other pages (probably).
After thinking about this situation for a bit I still find the situation a bit strange. Whatever settings you have in google chrome you can always open a link in other tab by clicking it. This is the behaviour of opening a new link rendering a notebook with voila. It is NOT a pop up. Its simply a new tab with a new link. Or am I wrong here (note: my knowledge of JS is very very limited)
ok, thanks. I made a final test: here the gist:
https://gist.github.com/joseberlines/8a5f0ba673d12034d69749cb831c2a88.js
and indeed changing the dettings totally changes the behaiviour. that leaves me wondering what is the approach in a JupyterHub environment to launch voila-solutions made by your colleagues that are available through urls

that's why I was saying earlier that showing links instead of using a custom button would maybe work better, and be less surprising from a user perspective
and actually, having an
HyperLink widget could maybe be a good addition to ipywidgets?
if you think about it, you never have, anywhere on any website, a button or an image that opens multiple tabs at once
You are right. Perhpas the approach is somehow strange. But there is certainly a use case here. For a particular persona (type of user) and a particular task (task 1) 4 different jupyterHub voila based notebooks should be opened. For the same persona (user) but task 2, other different 5 notebook solutions should be opened. And this is totally transparent to the user, who does not even know what is python nor a notebook. the user is given a single url (the one displaying the above example). I am talking about an organization where 50 to 100 people might have code solutions in notebooks and where another 6000 people dont even know that is a notebook.
I would be very interesting in knowing how jupyterHub based environments in big organisations go about "sharing work", also to people who are no coders. i.e. in an organization where everybody has access to the Hub anyone can render with coila notebook simply given an url. But you can not go around asking anyone to "open a notebook".
Hi @wolfv , thanks for suggesting, this is indeed one of the solutions, nevertheless it implies putting together stuff. INTEGRATING different solutions. For you to have an idea every of those solutions already include a bunch of menus and tabs and expansion panels. As analogy you can imagine that for doing job 1 you need MS word, and excel and for doing job two you need Word, MSexcel, powerpoint, and Access. Everyone is independent of each other. Every of the solutions is being developed by deifferent people. The agregator only opens word and excel for instance with url parameters in order to autoload the corresponding document. Putting excel and word in two tabs is not an option. Another analogy in the world of finance where JupyterHub is often used is having a complicated ipyvuetify based dashboard panel to invest in NYSE and another ipywidgets based dashboard for investing in raw materials. certainly in theory you could put both in two different tabs, but it is too much hacking. In a situation where there are, just say, 25 different dash boards, one starts to think about a kind of Launcher or aggregator. (as in pic above). I wonder how big tech companies go about this.
@trungleduc thanks. thats a very good point, its a semi-solution, that would not allow for modifying urls "on the fly" with parameters. i.e. you might open a voila rendered notetebook of the jupytehub as www.blablabla.internal.org/voila/render/path/name.ipynb/?document=doc23456?api=QHWE?autorun=True?task=whatever were the parameters would be used as predefined default values to be prefilled in ipywidgets and/or ipyvuetify components. I am aiming at propagating default values across multiple notebooks.
A pic is worth a million words. In the above shown pic every APP is made by a different coder who DONT HAVE PRACTICALLY ANY RELATION TO EACH OTHER.

HyperLinkwidget could maybe be a good addition to ipywidgets?
@martinRenou everything that avoids the user to have to go to JavaScript is a super plus. When bringing engineers to code who dont have CS background, neither any coding experience, speaking about more than one single language (being Python) is a no go. The moment you go: "well for this you need JS or HTML or..." its over. One of the superpowers of jupyterHub is that is one environment - one language. full stop. Its the most convenient place for non-CS background people.
it might need some additional love :)
Hi. I have an issue with Voila that i cant seem to narrow down where the issue is coming from. I am using either v0.2.x or v0.3 and I'm having an issue with a particular dashboard/Notebook. The Notebook works well in Jupyter. Voila works OK for all Notebooks except just one problem Notebook. I have the same issue on 2 separate machines. Please can anyone give me some clues on what i should be looking for. I can't supply the Notebook unfortunately.

we are actually doing that extensively in
xeus-python
for example you can pass a python function to pybind and it converts it automatically to a
std::function IIRC
an example of some python code in C++ with pybind11: https://github.com/jupyter-xeus/xeus-python/blob/master/src/xinterpreter_raw.cpp#L132-L137
basically, accessing attributes and methods of a
py::object is done using .attr("property_or_method")
One last thing. I am using it through qt-voila inside qt app, and debugging with pycharm. It creates python process with Popen and sys.executable -m voila . Then , it creates a process of python pydevd.py (jetbrains debugger agent) with ipykernel , so that it somehow entangled in the same pycharm kernel, and if I do a syntax mistake inside the notebook, it crashes. Also, can't stop it . But I guess that is solveable..
I am using voila for a real-time app, I have a loop which is a sync and updates a widget / bqplot continuously as data comes in. But once in awhile a client browser will see that it’s stop updating ... if I check the voila server it would have error message stating web socket is closed. Are there any ways to restart dead connection or any parameters that may help with that ?
Hi i am trying to set the file_whitelist (running voila with jupyterhub and cdsdashboards). I have tried as a command line arg passed to voila: --VoilaConfiguration.file_whitelist="['.']. I have also tried from my jupyter_notebook_config.py with c.VoilaConfiguration.file_whitelist = ['.'] and neither have an affect. I can modify the configuration.py in the voila site-packages and that works, but isnt really a solution. Could anyone assist me with getting this working?
@DHUKK For the complicated settings, I would suggest creating a file named
For example, the following content will allow you to serve your media files with the URL
voila.json in the directory where you start voila to define your parameters.For example, the following content will allow you to serve your media files with the URL
.../voila/files/static/...{
"VoilaConfiguration": {
"file_whitelist": [
".*\\.(png|jpg|gif|svg|mp4|avi|ogg)"
]
}
}
