[Rails] Re: I can't set the title of a page no matter what I have tried to put in my .html.erb file

Ruby on Rails Monday, January 15, 2018

I use
/app/views/layouts/application.html.erb

<html>
  <head>
  <%= yield :head %>
  </head>
  <body>
  <%= yield %>
  </body>
</html>

/app/views/foo/bar.html.erb

<% content_for :head do %>
  <title>A simple page</title>
<% end %>
 
<p>Hello, Rails!</p>

This way I can add "'meta descriptions" and "meta keywords" to individual pages
As Hassan mentioned http://guides.rubyonrails.org/layouts_and_rendering.html#using-the-content-for-method

I go  to http://127.0.0.1:3000 and I see the default template view   .\app\views\abc\def.html.erb

But even when I put  <title>asdf</title> it doesn't change the title.
Even if I do
<html><head><title>asdf</title></head><body></body></html>

it doesn't change the title.

If I go to the rendered HTML of the page, I can see what it's doing..

Suppose my .\app\views\abc\def.html.erb
is

<html>
  <head><title>aaaaa</title></head>
   <body></body>
  </html>

What gets rendered is this


<!DOCTYPE html>
<html>
<head>
<title>Test15</title>
<meta name="csrf-param" content="authenticity_token" />
<meta name="csrf-token" content="bDkNOUtlUKmlo1uzMRTqzCUCzBLX0q4/0NM8OfSXccoHocfYeZNFe+TsR8a4wvZhKakKRlXbU+NjWsnp4hNfXg==" />

</head>

<body>
<html>
<head><title>aaaaa</title></head>
<body></body>
</html>
</body>
</html>

So, what it is doing is rails is taking its own template then it dumps my template into its <body></body>

So the title isn't getting set
