Theme/Module dependencies

Hi guys I have another question:

Is there a way to create Orchard themes and modules to have dependencies on each other?

I have a module that outputs things to certain zones but the zones are defined in a theme.  The module is meaningless unless that theme is involved, so I'd like for the module to be dependent on the theme.

In that case that module's code should be part of the theme.

So instead of having Theme A and Module A each enabled separately, you are suggesting that I move the code in module A into theme A.  

Okay.  That makes sense.



1. Can I have migrations in themes to define models and parts?

2. What do I do if I need to create module B, which depends on module A?  Can I make module B now depend on Theme A?

1. You can, but they can only be run from the command-line (known bug:

2. No, but you just broken your own scenario: you said the module was meaningless outside of the theme. If that is not the case, then yes, it should be a module and your theme should have a dependency on it instead. But yes, theme-module interaction is not a perfectly well-rounded thing.

I didn't realize that a theme can declare dependencies other than "base theme".

But it seems that it doesn't automatically enable the dependent modules ... it only gives a warning message.  Is there a reason for that?

Dependencies here are meant as csproj dependencies.

oh.  What happens if i deploy a theme and it has a csproj dependency on a module that is not enabled (or worse, not installed)?  wouldn't it die?  or does it prevent activation?

I don't know. One would have to try.
