I’m working on a custom extension and I’m looking for a way to programmatically populate the notebook’s content with a JSON string.
I discovered this method:
DocumentRegistry.IModel.fromString(value: string): void which does the job.
I have a notebook widget, so I simply call
notebook.context.model.fromString(content), and it does indeed replaces the content of the notebook with my
content JSON string.
However, I’m noticing this error in the console which is also triggered whenever I try to save anything to the notebook that has been populated with JSON string using
The error mentions something about
contentChanged. After looking through the docs of
DocumentRegistry.IModel I discovered that it mentions the following in the description for
Should emit a [contentChanged] signal.
I’m wondering what it means and whether I’m missing something when I simply call the
fromString method. Should there be something else I should be calling before/after
fromString method in order to avoid the error? How exactly can I emit this signal?
Thanks in advance!
