Bu çalışma Rails 3'te nasıl çalışır?

Question

Rails projesini güncelliyorum ve Rails 3 ve Ruby 1.9.2'de çalışmayan bir kod parçası buldum (Rails 2.3 ve Ruby 1.8.7'de yapıldı) ve yine de oldukça dağınık görünüyor! Aşağıdaki hatayı alıyorum

def speech_box(title, options = {}, &block) 
    block_to_partial 'layouts/speech_box', options.merge(:title => title), &block 
    end 

    def block_to_partial(partial_name, options = {}, &block) 
    options.merge!(:body => capture(&block)) 
    concat(render(:partial => partial_name, :locals => options), block.binding) 
    end 

dediğim zaman: argümanlardan

<% speech_box("hello") do %> 
    <p>lorem ipsum</p> 
    <% end %> 

yanlış numara (1 için 2) Raylar çalışmaz bu gelir nasıl

3?

Answer 1

concat gitti:

aşağıda istenen gibi burada izidir. Basitçe concat'u kaldırın ve <% yerine speech_box'u <%= kullanarak aradığınızdan emin olun.

def block_to_partial(partial_name, options = {}, &block) 
    options.merge!(:body => capture(&block)) 
    render(:partial => partial_name, :locals => options) 
end 

<%= speech_box("hello") do %> 
    <p>lorem ipsum</p> 
<% end %>
