Best approach to render fragments

[Paolo Valleri]

Dear all, 

I am trying to understand which is the best way to render a fragment (which can be inside an other fragment and so on).

Lets take a very simple example in which I render a list of comments, and by clicking the 'more' button, few other are loaded with ajax.

So far I found a couple of working solutions:

1 approach:

-- layout.html has an include directive

-- wrapper.html extends layout.html and include comment.html

-- comment.html, renders comments.

When the controller receives an ajax call sets response.view to comment.html otherwise wrapper.html

2. approach:

- layout.html, same as before, it has the include directive

- empty.html, it has only the include directive

- comment.html. it has {{extend 'layout.html' if not request.ajax else 'empty.html'}} 

The first approach is difficult to maintain, the example is very simple, the chain can be arbitrary long. The second one doesn't compile, and empty.html is very ugly. I am wondering if could be possible to have extend and include more flexible and easier.

What exactly do you envision? What do you mean by "more flexible and easier"?

Note, rather than nesting lots of separate views, you might consider using Python logic within a given view. You could also have relatively simple request return rendered results directly rather than passing data to a view (if you return a string or HTML helper object, you don't need a view).

I don't know rails at all, and actually I don't even like to compare frameworks, but with flexible and easier I meant something like (rails): "render layout: false". In a talk I attended I remember that symfony has something very similar as well.

Given that, I know they are completely different frameworks but personally I don't know how to simply solve the example proposed in a cleaner way.

I see. Yes, I suppose it would be nice to have a conditional "extend" (equivalent to Rails "render layout: false"). You still wouldn't be able to compile the entire view, though, because the components of the view wouldn't be determined until request time.
