meta tags via helper - assistance needed

rubyonrails-talk
1

I am trying to generate meta tags based on the page. The meta_block call

in somepage.html.erb sets :meta_block and it is correctly yielded in

application.html.erb (except that only the last line is output).

But when otherpage.html.erb is rendered, because I don’t call meta_block

there is no meta content output. I thought the “|| meta_block” would

cause the helper to be called if :meta_block was not set.

How do I get all of the metat tags to be output on the page, and how do

I get it to happen if there are no per page keywords and description?

Thanks,

Matt

#application_helpers.rb

def meta_block(description = ‘’, keywords = ‘’)

tag('meta', :'http-equiv' => 'Content-Type', :content => 'text/html; charset=utf-8')

tag('meta', :'http-equiv' => 'Content-Language', :content => 'en-US,en')

tag('meta', :name => 'description', :content => SITE[:DESCRIPTION] + description)

tag('meta', :name => 'keywords', :content => SITE[:KEYWORDS] + keywords)

tag('meta', :name => 'robots', :content => 'all')

end

#somepage.html.erb

<% meta_block(“My per page description.”,“keywords, for this, page”) %>

some page’s content

…

#otherpage.html.erb

other-page’s content

…

#application.html.erb

My Application

<%= yield(:meta_block) || meta_block %>

<%= stylesheet_link_tag “application” %>

<%= javascript_include_tag “application” %>

<%= csrf_meta_tags %>

<%= yield %>

To accept content, showing default if none, in your layout <%= content_for?(:meta_block) ? yield(:meta_block) : meta_block $>

Called in your content.html.erb that uses the above layout. <%= content_for(:meta_block) do $>   <%= meta_block("Yield", "Got it now!)%> <% end %>
