orchardcms - Orchard CMS: Where new theme structure and files get saved when installed from Gallery

Question

I have a couple of general questions please. Just stepping into Orchard CMS. So apology if they look stupid!

Today I installed a theme called Metro from Theme Gallery. It is visible on theme selection page as well. But where the files and folder structure are got saved in Orchard CMS? I looked into Theme folder but it is not there. I want to see how the structure is placed so that I can create one myself

One more thing. Theme .png file shows a nice layout but when I activate it the layout comes up completely different. Why is this?

And finally, I installed my site using Orchard's web interface and it is running fine. But when I tried to run orchard > codegen theme CreditLine, it said Command codegen doesn't exist.

I then run Setup utility from command prompt (orchard >) and it displayed

A previous Orchard installation was detected in this database with this table prefix.

Which clearly says the setup I did through web interface was successful. But still I am not able to run codegen command or even help codegen. The latter command shows Command codegen doesn't exist!

Orchard version: v.1.10.1.0

Answer 1

1) It should be installed under Themes/TheThemeName, or locally, under src/Orchard.Web/Themes/TheThemeName

2) It could be that you installed an old theme. Not sure because you don't give many details over what goes wrong.

3) You first have to enable the codegen module. Do this by starting up your Orchard, go to modules => Codegen => Enable. Or run in the orchard.exe: feature enable Orchard.CodeGeneration
