Fastening of a stud to attach a deck railing to

[Gooner]

I need help with how to best attach this rule, which is red-masked in the attached image, from a strength standpoint. I plan to attach the posts for the deck railing to this rule. The rules have dimensions of 45x170 and the overhang over the laminated beam is 41cm. I was initially thinking of screwing through the rule directly into the end grain of the nailing rules, but it doesn't feel sturdy enough if I'm going to attach the railing to the outer rule. Please correct me if I'm wrong, those of you who are more knowledgeable =)

How is the red edge beam itself attached to the nail studs?
To make it really stable, I would have put metal brackets between the edge beam and the nail studs, where the railing posts are to stand. Something like this:

And then pulled a few through bolts with nuts to strengthen the joint.
And also attached the railing posts there.
In your pictures, it looks like the deck will be high above the ground.
Then it's important that it's built stably!

Yes, it's positioned a bit higher, so I want it securely built.
Ok, you mean that I pass a continuous bolt between the bracket and the edge beam and between the bracket and the nailing beam as well? Only a bracket on the beam closest to the post or on every post?

Is it enough to attach the posts as I'm trying to show in the first image below, or should I attach to the nailing beam as well? I'm thinking 2 M10 carriage bolts for each post against the edge beam?
(dimension for the posts is 2 x 45x95mm that are glued and screwed together.)



Is it just as good to attach the post between two nailing beams as in the image below, or should it "rest"/be attached against one of the nailing beams?

Or could this way be a better way to attach the posts?

I think it looks better if you can tolerate that the railing posts are not aligned with the outer edge rule.

But why 2 x 45x95 mm posts? Why not a 95x95 mm post in the corner?
Then the joint could consist of some carriage bolts through post-nailing rule and through post-edge rule.

Attached the "edge rule" to the nail strips with angle brackets on both sides and with through bolts.
Furthermore, I will attach the posts (screwed together 45x95) like the first railing picture I posted, i.e., from the inside with 2 diagonal carriage bolts.
Right or wrong, not entirely sure, but concluded that it is the best/safest with my conditions.
