No content

The
Layout
(for all pages)

Cut up
HTML

Cut up and reassemble
/
index.html
ideas.html
/app/views
pages/info.html.erb
ideas/index.html.erb
layout/application.html.
erb
I'm
embedded
ruby and will
produce html
it still has a
<%= link_to "link to my ideas", ideas_path %>
Slide 9
Slide 9 text
Links
link_to "text", "url"
link_to "all ideas", ideas_path
create all internal URLs with *_path
Slide 10
Slide 10 text
rake routes
$ rake routes
Prefix Verb URI Pattern Controller#Action
root GET / pages#info
ideas GET /ideas(.:format) ideas#index
new_idea GET /ideas/new(.:format) ideas#new
edit_idea GET /ideas/:id/edit(.:format) ideas#edit
idea GET /ideas/:id(.:format) ideas#show
see all the URLs and names of routes
just add _path or _url to the prefix:
root_path, ideas_path, new_idea_path,
...
let Rails take care of URLs for you!

Link to CSS with
stylesheet_link_tag
<%= stylesheet_link_tag "application", media: "all" %>

Slide 13

All my CSS files are magically
assembled into one file! exceedingly
clever way
to enable
caching
Summary
split up your html-files
one layout in app/views/layouts/
many views in app/views/
using ERB – embedded ruby inside <% %>
Convert all links
use link_to
never write URLs, use path-helpers instead
Move you CSS
to the asset pipline app/assets/stylesheets
Convert you CSS
to SASS, SCSS or LESS
Use all your knowledge of HTML Tags, CSS, ...
with tiny adjustments
