#3547 — File.open of HTML file removes code

Hey there,

I am trying to edit an erb file in ruby, however when I do:

file.open("index.erb")

It displays the information, but removes the Doctype, html, body, and
head tags.

Is there any way to read the entire contents of the .erb file?

Hello,

Please try to run this commands in your OS command prompt:

For Windows:

  type index.erb

For Linux/Mac OS X:

  cat index.erb

And then:

  $ irb
  irb(main):001:0> File.open('index.erb').read

Then compare system output with Ruby's output - if they have no 
differences - the problem is somewhere in your code. In that case please 
post your code to www.pastebin.com and give a link there.

Good luck. :)

File.open("...") just opens the file and returns an open File object, 
but it doesn't read it until you ask it to.

Try:

File.open("index.erb") do |file|
  file.each_line do |line|
    puts line
  end
end

Thanks to both of you!

I checked both of the code you guys suggested and it worked fine. 
However there is still a problem.

I am developing an application for a ruby class I am in, and I would 
like to edit some of that .erb file in an HTML textarea. I am using 
Ruby/Sinatra, and here is what happens:

If I print the data into a <div>, it will show everything including the 
doctype, body, etc.

Yet when I do this:

<textarea cols="93" rows="32" name="contents">
   <% File.open("views/layoutAdmin.erb") do |file| %>
      <% file.each_line do |line| %>
         <%= line %>
      <% end %>
   <% end %>
</textarea>

The textarea will take away all of the aforementioned tags. Like I said 
before, if I replace the <textarea> tags with <div> tags, it works fine, 
but I of course can't edit that content.

Is there some reason why textareas do not display this data?

You need to post that .erb file.  Or, even better, create the most 
minimal .erb file you can that will still exhibit your problem.

Huh?  What data?  What <div>?

Huh?  I thought we were talking about an .erb file?  erb files don't 
display anything.

Thanks again for the comment, it led me to test some stuff out and found 
it was TinyMCE javascript plugin that was removing the header and such. 
I tried testing if that was the case earlier but a refresh of the page 
didn't refresh the code, I had to actually reload the page for it to 
reset.

Sorry for the confusion, this is a great forum :)
