Redirecting from Websharper formlets
websharperf#

Hi,

If I have a Websharper formlet, the following code works:

1
2

Formlet.Run (fun x -> 
                 MyModule.Redirect("/Home/Index"))

where Redirect is defined like this:

1
2

[<Inline "document.location = $location">]
let Redirect (location: string) = X<unit>

But if I define redirection using RPC member of a control:

1
2
3

[<Rpc>]
member this.Redirect (location : string) = 
    this.Context.Response.Redirect(location)

then this code is never executed.

Are there any restrictions on Formlet.Run lambdas? What is the right way of redirecting after formlet execution?

Thanks in advance.

.

In general, redirection should be done using the JavaScript redirect version. If you want to make an RPC call after the formlet is ready, you can do:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16

// assuming this function:
[<Rpc>]
let myRP data : async<unit> = ...

// this is in a JavaScript region:
let myFormlet : Formlet<unit> = ...
let myFormletWithRPCAndRedirect =
    Formlet.Do {
        let! data = myFormlet
        
        Async.Start (myRP data)

        redirect "..."

        return ()
    }

Or if you want to wait for the RPC result before redirecting:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16

// assuming this function:
[<Rpc>]
let myRP data : async<bool> = ...

// this is in a JavaScript region:
let myFormlet : Formlet<_> = ...
let myFormletWithRPCAndRedirect =
    Formlet.Do {
        let! data = myFormlet
        
        async {
            let! success = myRP data
            if success then redirect "..."
        }
        |> Async.Start

        return ()
    }
