Task.js

// start/routes.js
Route.get('tasks/:id/edit', 'TaskController.edit') // updated this slightly
Route.patch('tasks/:id', 'TaskController.update')

// For the PATCH method, you might want to take a look at - http://dev.adonisjs.com/docs/4.0/request#_method_spoofing

// TaskController.js 
async update ({ request, params, response, session }) {
        // Get the task you want to update
        const task = await Task.find(params.id)
        
        // validate form input
        const validation = await validate(request.all(), {
            title: 'required|min:3|max:255'
        })

        // show error messages upon validation fail
        if (validation.fails()) {
            session.withErrors(validation.messages())
                    .flashAll()

            return response.redirect('back')
        }

        // persist changes to database
        task.title = request.input('title')
        await task.save()

        // Fash success message to session
        session.flash({ notification: 'Task update!' })

        return response.redirect('back')
    }

This is awesome. Thanks for the update on this

Hi @ammezie,

This is what my edit form looks like
<form action="{{ 'tasks/' + task.id + '?_method=PUT' }}" method="POST">

However I keep ending up with this URL route:
http://127.0.0.1:3333/tasks/3/tasks/3?_method=PUT

Which results in getting an error:

HttpException
Route not found /tasks/3/tasks/3

What can I do to address this?

Thanks

Since you are using PUT, change your route to use it instead of PATCH
