Stupid questions about erb

Rails
1

I have been trying to find these answers in Google, but not getting any
clarity.

I am writing in Rails 2.3.2 but have always lived in a 1.2.x world.

In the 1.2.x world, putting this in an rhtml file would always render
properly for both screen & print…

<%= stylesheet_link_tag ‘reports_print.css’ %>

In current erb file, screen is rendered properly but not print.

How do I designate it to use the public/stylesheets/reports_print.css
for both screen and print now?

Hello Craig:

<%= stylesheet_link_tag ‘reports_print’, :media => :all %>

will generate:

See examples in the documentation:

yes, thanks. I think the commented lines were my 1.2.x style and I had
already found that and for some strange reason, that particular report
formatted print the same as screen. But better to make it predictable
and follow the rules.

I think that I don’t understand the differences between erb files and
rhtml files and before I write a bunch of view files, it would be nice
to understand the differences. Does anyone have a link to a page that
explains the differences between rhtml and erb?

Hello Craig,

There’s no difference between rhtml and erb, it was a change in naming
conventions:

“We’ve separated the format of the template from its rendering engine.
So show.rhtml now becomes show.html.erb, which is the template that’ll
be rendered by default for a show action that has declared format.html
in its respond_to. And you can now have something like show.csv.erb,
which targets text/csv, but also uses the default ERB renderer.”

Cheers,
Nicholas
