Add base path configuration option

[smlparry]

Hey there 👋

I ran into an issue with Inertia that I think could be fixed quite easily. I'm using nginx to reverse proxy my subdomain to a nested route in Rails, the configuration looks like this:

Which causes Inertia to rewrite the current path to /admin rather than just /

Ive managed to fix this by setting a before action in my controller as such:

And this works correctly:

It seemed easy enough to add this as a configuration option to the Rails gem and I would imagine it being set in the initializer

FYI I havn't tested this code, but I hope it illustrates the point :)

Hi @smlparry thanks for opening up the PR here...

Let me see if i understand this correctly...

You are using nginx to send browser traffic to trainer.fitterapp.local to the trainer.fitterapp.local/admin route within the rails app.

Is this so you can nest admin based routes/resources in the /admin namespace within Rails?

And then also you don't want the user to see /admin in the url?

[smlparry]

Thats exactly right :)

i see... wouldn't this condition still exist without using inertia? for example, a theoretical update action with standard, non-inertia Rails code:

def update
  @thing = Thing.find(params[:id])
  if @thing.update(thing_params)
    redirect_to admin_thing_path(@thing)
  else
    render :edit
  end
end

will redirect the user to http://trainer.fitterapp.local/admin/things/:thing_id right?

Closing because we don't think this is something inertia should be responsible for given that the same shortcomings exist in rails. Feel free to re-open (or add an issue) if we're mistaken!
