Re: [Rails] 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 Saturday, January 13, 2018

Robert,

To amplify Hassan's answer a bit ... and you probably already know this ...

You can only have one head section and, I believe, it has to be the first tag after the html tag.  If I remember correctly, most browsers will ignore misplaced head tags.

Rails will not look at the rendered text and say, "Oh my, Robert put in a head section.  Let me move it immediately after the HTML tag."

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
