I have metal working (thanks to Railscasts), but I have a haml template that I want to render instead of just plain text. Apparently you can render ERB , but I don't see any place to do the same with haml. Is it possible or will I just have to live with using the plain rails routing if I want to continue using haml?
Thanks!
Haml, like ERB, has a Ruby interface. However, also like ERB, using it without setting up the proper template caching (as Rails normally does for you) will make it very slow, almost certainly slower than Rails' routing. So be careful, and use #def_method rather than #render.

I asked a specific question about problems I'm having with a specific gem intended to do this in a separate thread ( https://stackoverflow.com/q/18577033/1206117?sem=2 )
But I feel I may be on the "wrong boat" somehow because all of the questions I find about Rails/Haml/JST-templates are at least 2 years old, or go unanswered.
I'm writing an app with a lot of client-side JS and so want to use templates to render views (I'm using Backbone). I want to use Haml to write the templates.
I'm not looking for a debate about which gem/method is better, I'm looking for A WAY that works and has current support and active use. At present I cannot write my JS templates in Haml, and it's a bummer. I'm avoiding CoffeeScript at present since I'm still rather new to Javascript.
I've submitted an issue to the haml git repo.
https://github.com/haml/haml/issues/716
Looks like https://github.com/netzpirat/haml_coffee_assets gives you what you want. (window.JST templates, written in HAML, with inline coffescript support)
I am trying to make common templates that used both by Rails and the client side, ie in coffescript.
I use hogan_assets and haml_assets to export templates to JS. However I can't find a way to use HAML and Mustache to render server-side views.
Partial solution is described here, but it doesn't work with view helpers, ie, "render partial" doesn't work.
For some unknown reason chaining of handlers, such as .mustache.haml, doesn't work, and I can't find neither good info on Rails template handler nor an example on how to build "chainable" handler.
I've been experimenting with something like smt_rails lately, but I have yet to find a silver bullet.
I'm working with a large project where the templates are written in erb. We're getting more and more into client side rendering of parts of the project and we have lots of exact duplicates in mustache of our erb templates.
I'd like to change the erb templates that are replicated in mustache to mustache and print the js templates out from those templates.
I haven't been able to figure out how to mix templating languages in rails though, is this possible? I'd rather not rewrite all the erb templates in mustache.
Thanks!
Maybe Isotope could be useful for you? I never tried it though.
I fear you'd have no direct solution...
An alternative:
You could reuse your good old html created by ruby if you insert in handlebars templates. But it's another js library...

In my next rails project I want to use liquid pages (so that my graphic designer can do his stuff without bothering be :D) By my question is
will i be able to use
render_component and render :partial commands inside my liquid layout. If possible how
thanks in advance
cheers,

Liquid provides an include tag you can use inside a template to include external templates. However, it isn't equiparable to the render component or partial feature in Rails.
Also, render component has been deprecated times ago. You shouldn't use it.
As far as I know, .rhtml is deprecated in Rails 2. In some guides there is only .erb, but both RubyMine and NetBeans IDE generate .html.erb and I've also seen it many people using.
I've tested both and they seem to work fine without any errors or warnings, but which one is correct? .erb or .html.erb
file_name.format.extension is the accepted convention now, where format is html, xml, json, anything really and extension is erb if you're using erb, haml if you're using haml and so on.
Typically you want to have the format in the file name.
