Re: have an object available in every templates

Well, I was curious to see if it worked with a context processor so I tried and indeed it works. After all it's only returning an object or list of objects in a dictionary. Now I don't know which method is the most efficient.

The context_processor will be called for each and every RequestContext (so for each and every view AND templatetag creating a RequestContext), so better to avoid anything "intensive" here.

Also, it won't have access to the existing context - which may or not be a problem, but for something "my favorite books" (which really means : "the favorité books of request.user"), you can bet one day or another you will want to show "the favorite books of _another_ user", and this is something that won't work with a context processor.

To make a long story short : use a custom template tag that will take the user as an argument.

My 2 cents...

Hi,

I don't know if this is possible or how to do it. I would like to write a sort of context processor where I pass an object to the template. I have always passed strings to these variables. Let's say I have a Book model and in a view I list the latest books I've added to the database. In the corresponding template I will then have an objects list with these objects. But I also want to be able to call a variable containing another list of objects, say my favorite books, without having to pass it explicitly from the view and being able to call it from any template.
Can I do it with context processors, or anything else actually?

Thanks.
