Thanks — I saw this while I was searching around but I'm hesitant to add libraries without understanding all my options, but I'll look more into it

Yeah I can imagine... I appreciate the help. I think I'll just add the unique checks before the create/update and call it a day

So basically, do a check on the slug and return a helpful error if it is taken. If the unlikely scenario happens where its taken right after the check, then just return a generic exception since it will probably never happen anyway

Ok, thanks. So I might be best off making some sort of helper and re-using it in my services like this?

this could still error after checking though (theoretically — if one was created in between)

URL Parameters and/or data loading in layout files
im probably best off just not creating a layout file and instead a layout component that i just wrap every page with.

URL Parameters and/or data loading in layout files
ah ok. i read about cascading parameters a bit but it seemed like not a great solution having to perform the same logic in every single child of a layout when all i want is a path parameter 😦

URL Parameters and/or data loading in layout files
I'd like to essentially do the opposite - read a value in the layout from the page (in this case a URL parameter)

Redirect after form POST Blazor Static
@D.Mentia figured it out 😎 . The NavigateTo method throws if the page is statically rendered. this exception is meant to get caught by the framework to handle the redirect
