Question

<%= link_to \'Destroy\', post, :method => :delete, :onclick => \"return confirm(\'Are you sure you wa         


        

Answer 1

Check the whitespaces.

I checked all the comments here. All the includes were set correctly. But I noticed that deleting articles did not work, while deleting comments would work. After rewriting some code and checking here and there, I found two files that looked identically in the editor, but one version would work and one would not work!

curry-blog/app/views/articles/index.html.erb:

Listing Articles
<%= link_to 'New article', new_article_path %>

  
    
    
    
  
 
  <% @articles.each do |article| %>
    
      
      
      
      
              
    
  <% end %>
Title
Text
<%= article.title %>
<%= article.text %>
<%= link_to 'Show', article_path(article) %>
<%= link_to 'Edit', edit_article_path(article) %>
<%= link_to 'Delete', article_path(article),
              method: :delete,
              data: { confirm: 'Are you sure?' } %>

However, looking at the files with xxdiff I found that in one version only tabs where used, while the other also used blanks. Probably, from copy pasting code from the tutorial. Replacing the blanks with tabs did therefore fix the problem.
