Node.js and npm version

node.js: v10.8.0
npm: 6.4.0

Sample Code (to reproduce the issue)

controller:

return view.render('pages.confirmation',{status:0})

return view.render('pages.confirmation',{status:1})

view:

{{status}}
@if(status===1)
  do sth
@elseif(status===0)
  do sth
@endif

The view evaluates the value as empty string / null / undefined and prints nothing to screen when status is 0 . If i set status to other than 0, it prints the number to screen properly. Is this a bug? If it is not, it should also print 0 (integer).. I am not sure the problem is about the data sending mechanism or printing data to screen mechanism.
Thank you for your helps.

Yes, seems like a bug. As a workaround, you can say.

view.render('pages.confirmation',{status: String(0)})

and use it follows inside the view

@elseif(status === '0')

Okey, thank you for confirmation. There are lots of workaround to resolve this issue. No problem for me but I just want to inform you. 👍

Late to the game, but have seen this is still open.
I don't think this is actually a bug on AdonisJS side, as after briefly looking at the code,
view.render(...) is just a proxy for the same function on the Edge template engine.
