render :inline => '<html><b>123</b></html>' #=> Content-Type: text/html; charset=utf-8

# Good

render json: {1 => 2}.to_json  #=> Content-Type: application/json; charset=utf-8

# this was correct

render xml: '<xml><foo>123</foo></xml>'  #=> Content-Type: application/xml; charset=utf-8

# correct, too


render text: 'hello'  #=> Content-Type: text/html; charset=utf-8

# What? text/html? Why?

# Forcing text/plain :

render text: 'hello',  content_type: 'text/plain' #=> Content-Type: text/plain; charset=utf-8


# Important! Render inside a format block overrides content_type:


respond_to do |format|
  format.js do
    render 'projects/new', layout: nil  #=> Content-Type: text/javascript; charset=utf-8
  end
end

# This is actually logical

# But if you need to override it:


respond_to do |format|
  format.js do
    render 'projects/new', layout: nil, content_type: 'text/html'  #=> Content-Type: text/html; charset=utf-8
  end
