This line admittedly does bother me as we are doing a clone to pass the data. I did not figure out what the borrowing rules here should be.

Pretty sure the answer here is to actually do what the method name implies, make a NewPost from the PostForm:

pub fn from_post_form(form: PostForm, id: i32) {
    ...
}

...

let new_post = NewPost::from_post_form(data.into_inner(), user.id);
Enter fullscreen mode Exit fullscreen mode

Since you don't need the Form<PostForm>, there's no need to clone anything, just pass ownership of the entire object.

Ah! This is good, feels much better, because we don't use data later on we can give ownership away. I also should have read the WebForm doc, into_inner() really simplified things.

Thank you! I'll add a note to take a look at this comment.
