Let's say I have multiple blogs on my Orchard site. How do I create a projection that shows posts only from the blog that I specify e.g. either by its name or id?
I think it can be done using a custom filter but there seem to be no doc/howto out there.
Please let me know where I should put the code too, I've been programming for ages but am very new to Orchard.
You have to implement the IFilterProvider interface, you can see how to do it here: http://www.ideliverable.com/blog/writing-an-orchard-webshop-module-from-scratch-part-5
