Add this line to your application's Gemfile:
gem 'cookies_eu'And then execute:
$ bundle
Run the installation generator:
$ bundle exec rails g cookies_eu:install
Or manually add in application.js:
//= require cookies_eu
And in application.css:
*= require cookies_eu
Or, if you have application.scss:
@import "cookies_eu";
Remember to restart your server!
In your view add
= render 'cookies_eu/consent_banner'You can add a link parameter to link to your cookies explanation page (you have to create the page and controller for this)
= render 'cookies_eu/consent_banner', link: '/cookies'You can add a target parameter to the link to open in a new tab
= render 'cookies_eu/consent_banner', link: '/cookies', target: '_blank'If you wish to customize the style of the div the classes are:
.cookies-eu /* main div */
.cookies-eu-content-holder /* content holder */
.cookies-eu-button-holder /* button holder */
.cookies-eu-ok /* button */
.cookies-eu-link /* link */If you wish to customize the HTML, create a folder cookies_eu, create a partial _consent_banner.html.erb and paste the HTML from here
If you wish to run some arbitrary code when the user acknowledges the cookie message, you can register a callback. This is useful if you wish to persist the user's preference to the database.
document.addEventListener('cookies-eu-acknowledged', function() {
// The user has acknowledged cookies! If they're logged in, make an api call
// so we remember their preference.
fetch('...');
});This gem uses a cookie called cookie_eu_consented to track whether a user has accepted the cookie notice and whether it needs to be shown again or not.
Is supported out of the box, just require it before cookies_eu
//= require turbolinks
//= require cookies_eu
Sample of cookie info (in haml form)
Cookies are small text files which are downloaded to your computer, tablet or mobile phone when you visit a website or application. The website or application may retrieve these cookies from your web browser (eg Internet Explorer, Mozilla Firefox or Google Chrome) each time you visit, so they can recognise you, remember your preferences and provide you with a more secure online experience.
Generally, cookies are very useful and are a common method used by almost every website you visit because they help to make your online experience as smooth as possible. For security reasons, many websites will not function at all without the use of cookies (or other similar technologies, such as "web beacons" or "tags").
Cookies generally do not hold any information to identify an individual person, but are instead used to identify a browser on an individual machine.
If you prefer, you can restrict, block or delete cookies by changing your browser settings but that may mean that the website won't work properly

These cookies are essential in helping you to make use of the features and services we offer on the #{INSERT SITE HERE} website. Without these cookies, the services you want to use cannot be provided. These cookies do not gather information about you that could be used to identify you, and they do not monitor or remember where you have been on the internet.
These cookies allow us to provide you with a better online experience when you use our website. They do not gather or store any information which would allow us to identify you personally.
Performance cookies help us to understand how our customers use our site, so we can keep our products and services relevant, easy to use and up to date. For example, we can see which products and services are most popular, identify when and where errors occur, and test different versions of a page in order to provide an improved online experience.
Sometimes, the services we use to collect this information may be operated by other companies on our behalf. They may use similar technologies to cookies, known as "web beacons" or "tags". These are anonymous and, as they are only used for statistical purposes, they do not contain or collect any information that identifies you.
We have relationships with carefully selected and monitored suppliers (third parties) who may also set cookies during your visit. The purpose of these cookies is "behavioural advertising" (also known as "behavioural targeting" or "remarketing"), which is a means of showing you relevant products and services based on what you appear to be interested in. Although these cookies can track your visits around the web they don't know who you are. Without these cookies, online advertisements you encounter will be less relevant to you and your interests.
