I'm starting a plotly and dash application with Python. At the top is a menu with three tabs: Home, Create, and Load. We start off at the Home screen.

My problem: through clicking a button within the 'Home' tab, I would like to redirect to the 'Open' tab. Any ideas on how I could go about clicking a button within one tab in order to go to another tab?

Included below is the file where I"m trying to solve this issue:

i'm trying to learn dash i'm at the third tutorial but it raise this error whenever i run the file(python app.py)

dash.exceptions.IncorrectTypeException: The input argument input.value must be a list or tuple of dash.dependencies.Inputs.

this is the code i'm running :

From reviewing the dash documentation, I cannot see any syntax or examples for nesting a hyperlink within an image. I am essentially trying to achieve the following but in a dash layout friendly format (regardless of whether it uses html or dash-core-components):

I want to deploy a dash application on Gunicorn. But I am not able to do so. I see no errors appearing on the screen when I execute the gunicorn :

Versions:

• gunicorn (20.0.4)
• dash (1.17.0)
• dash-core-components (1.13.0)
• dash-html-components (1.1.1)
• dash-renderer (1.8.3)
• dash-table (4.11.0)

I am trying to deploy a Plotly Dash app as an AWS Lambda using Serverless framework. The app works as expected locally and I can start it using serverless wsgi serve command. serverless deploy reports success. However when invoked, lambda fails with the following error:

I created a global df variable, and I also created a csv file upload component and component that show df columns. I would like when I load the file that the component options change but I have this error options[0].label in Dropdown with ID "col-1" is required but it was not provided. How can I solve this?

Here is the sample of my code:

I am not able to reproduce the exact output of the content-property of the dcc.Upload component.

If I upload the file my_excel.xlsx to the dcc.Upload component, my callback-function receives a "base64 encoded string" (according to the dcc.Upload documentation). I don’t know how to reproduce the exact same string without the dcc.Upload component (I want to use the Output for Unit Tests).

my current approach:

I have a client with an open connection to a server which accepts push notifications from the server. I would like to display the data from the push notifications in a plotly/dash page in near real time.

I've been considering my options as discussed in the documentation page.

If I have multiple push-notification clients running in each potential plotly/dash worker process, then I had to manage de-duplicating events, doable, but bug prone and quirky to code.

The idea solution seems to be to run the push network client on only one process and push those notifications into a dcc.Store objects. I assume I would do that by populating a queue in the push clients async callback, and on a dcc.Interval timer gather any new data in that queue and place it in the dcc.Store object. Then all other callbacks get triggered on the dcc.Store object, possibly in separate python processes.

From the documentation I don't see how I would be guarantee the callback that interacts with the push network client to the main process and ensure it doesn't run on any worker processes. Is this possible? The dcc.Interval documentation doesn't make any mention of this detail.

Is there a way to force the dcc.Interval onto one process, or is that the normal operation under Dash with multiple worker processes? Or is there another recommended approach to handling data from a push notification network client?

I am trying to migrate my Django database after installing django_plotly_dash and am receiving this error even though I have dash installed and working fine. Any ideas why this will not work when I try it with Django?
