Add content to existing model templates -> how?

[MalfuncEddie]

Hi,

I am probably missing something basic while reading the documentation. In the getting started section it states "Add content to existing model templates"
Am I correct that this means I can add it to a core model?
Because this conflicts with "Modify core models is not allowed"

eg:

I have a model and I assume that I get all this working (with the very good and impressive documentation). I've got create edit table views/templates just like de documentation.

The model is a "child" of the core model VM ( VM has one or more the new models). The documentation says I can inject a template in a core model. So I should be able to inject a list of the models in the VM template?

I was wondering if this is described somewhere? The plugin tutorial seems to contain the plugin to it's models it self.
What if I want to add the AccessList model from the tutorial to a device and make it visible that there is a AccessList in de device view? is this possible?

No. It means you can add content to the views of an existing core model - such as data from your plugin's own models, which relates to an existing model. But you cannot modify the core models themselves.

For example: if you have a Foo model, which contains a reference to Device, then when viewing a Device you can also show the related Foos by adding content into the Device view. But this does not change the Device model.

So if my "plugin model" has a remote if to a core model I can list the "plugin objects" in the core model view?

Your example is what I am looking for in the documentation but this does not seem present in the documentation tutorial?

I think what you need is here: https://docs.netbox.dev/en/stable/plugins/development/views/#extending-core-views
