Rendering file with MIME Type in rails

Question

Here\'s the code:

render :file => @somedir + \"/blah.xml\"

...but the resulting MIME type is text/html when I check in FireBug. How do I

Answer 1

Take a look here. Basically you need to use render :xml => blah.to_xml

Answer 2

What about

headers["Content-Type"] = "text/xml"

? Hope that helps.

Answer 3

Actually there are two ways to set the content-type (I think this is what you mean by mime-type). You should use the second option, if it works for your Rails version.

class FileController < ApplicationController

  def index
    filename = 'some.xml'

    extname = File.extname(filename)[1..-1]
    mime_type = Mime::Type.lookup_by_extension(extname)
    content_type = mime_type.to_s unless mime_type.nil?

    # 1
    #headers['Content-Type'] = content_type
    #render :file => filename

    # 2
    render :file => filename, :content_type => content_type
  end

end

Hope this helps!

Answer 4

Per http://api.rubyonrails.org/classes/Mime/Type.html, you could specify it like so:

render file: @somedir + "/blah.xml", mime_type: Mime::Type.lookup("text/xml")  

Answer 5

render :file => @somedir + "/blah.xml", :content_type => Mime::XML
