Hamlet templates doesn't update

[Дмитрий Долгов]

I'm new in Yesod. I have strange problem (i asked about this on reddit and stackoverflow, but nothing) - I have created new Yesod application with cabal-dev:

yesod init

and tried modify templates/homepage.hamlet . When I restarted development service, I didn't see my changes) When I have deployed this app into Heroku, there is my changes well. I don't know reason of this - can anybody help me?

So we are assuming you are using `yesod --dev devel`. You should be able to manually run `cabal-dev build` to see your changes. Also, if you touch a file that uses templates/homepage.hamlet the changes should show up. Do those work?

I have ran 'cabal-dev build' (also 'yesod build --dev', but i think, this commands are equals) - my application was rebuilt, but it still didn't contains my template changes. Also, I have changed page title in getHomeR handler, rebuild app, and nothing! And yes, I use 'yesod --dev devel' to run development server.

This is very strange. Can you generate a new site with `yesod init` and not change anything at all, but just try to modify one of the templates and verify that you still don't see any changes?

What version of ghc are you using?

I found solution, but it's surprisingly for me)

I have generated new app with postgresql:

yesod init

cd TestChange

cabal-dev install

modified homepage.hamlet:

+<h1>Test change

<h1>_{MsgHello}

and run dev server:

yesod --dev devel

Yesod devel server. Press ENTER to quit

Rebuilding application... (using cabal-dev)

Starting development server...

Starting devel application

Devel application launched: http://localhost:3000

And I don't see any changes. After 'cabal-dev build' nothing has changed. But when i run

cabal-dev install

and start dev server, template modifications were i place!) This is correct behavior of yesod?

The instruction to run cabal-dev install is given in the output of yesod init.

But still, this should be easy for yesod --dev devel to detect so I created an issue for it: https://github.com/yesodweb/yesod/issues/565

[Дмитрий Долгов]

Hm...but when I ran 'yesod --dev devel' cabal-dev directory already exists, because I created app as:

yesod init

cd TestChange

cabal-dev install 

Or am I missing something?

Those commands should work (yesod --dev devel would come after). Can you update the github issue with the exact commands that create the issue?
