New buffalo project on Windows: could not find template items/index.html

Question

I'm working with someone to build a Buffalo app. They are on Windows and I'm on Linux. After generating a model, they get a 500 error when visiting the list route: http://localhost:3000/items/ . The problem is very similar to issue 1757 except the issue is fixed and the exact same source works on Linux and Mac. I suspect it's due to backslashes instead of forward slashes but can't confirm. I was able to reproduce this on my Windows by creating a new buffalo project, configuring the database, generating a model and then visiting the route. This fails in both MinGW and Powershell. I'm using Go modules ( GO111MODULE=on ) and have cleaned the modules cache, rebuilt buffalo and buffalo-pop .

Can someone confirm this works/fails on Windows? Besides having them migrate to Linux, what else can I try?

$ buffalo version
time="2019-12-16T17:55:24-05:00" level=info msg="Buffalo version is: v0.15.3"

$ buffalo-pop pop --version
v4.13.0

Answer 1

Yes, I confirm this behavior. What you should do is substitute

    return c.Render(200, r.HTML("domain/view.html"))

with

    return c.Render(200, r.HTML("domain" + string(os.PathSeparator) + "view.html"))

It should work on all platforms. For some reason, path.Join() is not working either.
