Action is not allowed Template not found

[VadimN]

Hi,

Using Websocket technology to periodically send new rows to the page.

Under lite version all works fine.

Server log for getting page, establishing WS connection, sending occasional new row to the page:

The problem occurred when switching from Mojolicious::Lite to the full version.

Server log looks like this:

:19.53478] [6264] [debug] 404 Not Found (0.055844s, 17.907/s)

In the Lite app theris function call

websocket '/tap' => sub {
    my $c = shift;

    #get some data from outside
    #...


# as the test showed, this is not necessary for lite app
#    $c->on(message => sub {
#    });

    my $id = Mojo::IOLoop->recurring(3 => sub {

        #check for the new data
        #...
     
        if (new data found) {
            ...
            my $html = $c->render_to_string('datarows');
            $c->send($html);
            $c->app->log->debug("html sent; new id = $max_id");
        }
    });

    $c->on(finish => sub {
        Mojo::IOLoop->remove($id);
        $c->app->log->debug("WS for table append closed");
    });

    $c->app->log->debug('WS for table append opened');
};

This is transforms to couple parts in full app code.

In startup function

    $r->websocket('/tap')->to('front_end#tap');

In the FrontEnd controller:

sub tap {
    my $self = shift;

    # get some data
    #...

    my $id = Mojo::IOLoop->recurring(3 => sub {
       

        # check for data

        # if found
        if (...) {
            ...
        #all the same
};

Why was he asking about a nonexistent template?

Try an action name other than `tap`.  tap() is a method in Mojo::Base which just about every class in Mojolicious inherits from.

In the Mojolicious::Lite app, you do not have a subroutine action named `tap` -- you just have a callback.  In the full Mojolicious app, you have a subroutine action named `tap`.  Specifically, these keywords are hidden from the router.
