i don't see why on-install and if it can be done at install time why not just do it on-demand of the model... if its slow cache but still ondemand,
providing models that we gen will likely require a full stack of development as git/github isn't really ideal for stuff like this On 25 February 2017 at 15:15, Oliver Walters <[email protected]> wrote: > I personally find the idea of on-demand model creation appealing. > > I think that if we are to "promote" this as the preferred method, it should > be improved through simplification and consolidation. > > Scripted models have only been added in the last week.
