a couple of ways I have done this in the past put the data in hidden fields, access the data in js/coffee # single value <%= hidden_field_tag “foo_name”, @foo.name, { :id => “foo-name” } %> $(‘#foo-name’).val(); # when the ‘value’ has multiple attributes <%= hidden_field_tag “foo”, @foo.id, { :id => “foo”, “data-first-name” => @foo.first_name, “data-last-name” … Read more
Try using raw(somePost.content). Alternatively, somePost.content.html_safe.
just pass the :locals to the erb() in your routes: get ‘/hello/:name’ do erb :hello, :locals => {:name => params[:name]} end and then just use it in the views/hello.erb: Hello <%= name %> (tested on sinatra 1.2.6)
Haml rocks. I haven’t seen any recent performance numbers but it is pretty close to erb these days. I think that it might be faster than erb if you turn on ugly mode (which prevents the pretty indentation) We’re doing 2.8 million pageviews a day with Haml. There is a benchmarker checked into the Haml … Read more
Nothing, really. It’s just a change of philosophy between Rails 1 and Rails 2. Before Rails 2, you had file.rhtml, file.rxml and file.rjs. In Rails, that changed to file.content_type.template_engine. So with file.html.erb, the content type is html and the template engine is ERb. rxml is now xml.builder and rjs should now (mostly) be js.rjs In … Read more
You can use from the command line html2haml html2haml your_erb_file new_haml_file If you want to convert all your files in one go, look at this article : http://shifteleven.com/articles/2008/06/08/converting-erb-to-haml-snippet
You could try going to Language > H > Html and that should highlight stuff.
For a simple solution, use OpenStruct: require ‘erb’ require ‘ostruct’ namespace = OpenStruct.new(name: ‘Joan’, last: ‘Maragall’) template=”Name: <%= name %> <%= last %>” result = ERB.new(template).result(namespace.instance_eval { binding }) #=> Name: Joan Maragall The code above is simple enough but has (at least) two problems: 1) Since it relies on OpenStruct, an access to a … Read more
<%== is equivalent to raw. From the Ruby on Rails Guide: To insert something verbatim use the raw helper rather than calling html_safe: <%= raw @cms.current_template %> <%# inserts @cms.current_template as is %> or, equivalently, use <%==: <%== @cms.current_template %> <%# inserts @cms.current_template as is %>
You can try with something like this: <%= f.input :quantity, input_html: {value: f.object.quantity || ‘1’} %>
