[RUBY] Rails Flash Message

Flash Message implementation

1. View creation


  - flash.each do |key, value|
    = content_tag :div, value, class: key


--When using devise, a flash object is automatically created and multiple messages are saved with key :, value: values. --By using each statement, these are taken out one by one and displayed by using "key" as "class name for CSS" and "value" as "message body to be displayed". --Display on screen


 = render 'layouts/notifications'
 = yield

↑ Since the view file of each page is displayed in the yield part, write = render'layouts / notifications' on it to display the flash message at the top of the page. ↓ image.png

  1. Flash Message Styling


.notification {
  .notice {
    background-color: $light_blue;
    color: $white;
    text-align: center;

  .alert {
    background-color: $alert_orange;
    color: $white;
    text-align: center;
//Separate notification and alert messages


@import "reset";
@import "config/colors";
@import "modules/flash";
//flash.Reflect scss
//reset.Described under the css file name defined as css

3. Japanese localization of Flash Message

--Create new files named "devise.ja.yml" and "ja.yml" in the "config / locales" folder


module ChatSpace
  class Application < Rails::Application
    config.i18n.default_locale = :ja
//config/application.Add one sentence to rb and set Japanese
