Hello @vuhoanglam,

The ctx.View returns an error. This error is always logged to your terminal screen (or log file) if the logger is not disabled.

If the application is running under debug log level (app.Logger().SetLevel("debug")) then the client will receive the error text too but if not (default behavior) then it just returns the error the caller, so you can catch it.

Example Code:

<!-- ./view/fallback.html -->
<h1>Fallback view of {{.ViewRequested}}</h1>

package main

import (
    "github.com/kataras/iris/v12"
)

const defaultViewName = "fallback"

func main() {
    app := iris.New()
    app.RegisterView(iris.HTML("./view", ".html"))
    app.Get("/", index)

    app.Listen(":8080")
}

func index(ctx iris.Context) {
    var viewName = "blabla"

    err := ctx.View(viewName)
    if err != nil {
        ctx.View(defaultViewName, iris.Map{
            "ViewRequested": viewName,
        })
    }
}

I assume you just want to render something as 'fallback' - that you can do already as shown above.

Now, if you are asking if you can disable this log line of "template x does not exist" then it's a different thing. We can create a config field in order to disable that message :)
