Ruby on Rails SEO Metatags plugins for ActiveRecord models
Gemfile.rb
:
gem 'seorel', '~> 0.5.0'
# the edge version can be had using:
# gem 'seorel', github: 'dalpo/seorel'
Console
:
$ bundle install
$ bundle exec rails generate seorel:install
$ bundle exec rake db:migrate
It will generate the seorel.rb
initializer and a new migration.
You could change default meta tags values into the seorel initializer:
Seorel.configure do |config|
config.default_title = 'My default page title goes here'
# config.default_prepend_title = nil
config.default_append_title = ' / Every title will be appended with this string'
config.default_description = 'Lorem ipsum sit dolor...'
# config.default_prepend_description = nil
# config.default_append_description = nil
config.default_keywords = 'RUBY ON RAILS,SEO,METATAGS'
config.default_image = 'http://www.example.com/share_image.png'
# config.store_seorel_if = :empty # Available values :empty | :changed
config.default_og_metas = {
type: 'website'
}
config.default_twitter_metas = {
card: 'summary_large_image'
}
# config.enable_pagination = true
# config.pagination_format = ' - Pag. %page%'
# config.pagination_parameter_name = 'page'
end
Given a sample model Post:
rails generate model post title:string description:text, publish_date:date
Edit app/models/post.rb
:
class Post < ActiveRecord::Base
extend Seorelify
seorelify title: :customized_title, description: :description, image: :share_image
# Or more simply:
# seorelify :customized_title, :description, :share_image
def customized_title
"THE BLOG: #{self.title}"
end
end
This will use the customized_title
and the description
methods as references to generate automatically the related metatags.
Note that the title and description will be sanitized from HTML and truncated to 255 characters.
In your controllers you may add_metatags either like a before_filter or within a method.
class PostsController < ApplicationController
def index
###
# Custom meta tags
add_metatags({
title: 'My custom meta title',
description: 'My custom meta description',
image: '/sample_image.png'
})
...
end
def show
@post = Post.find(params[:id])
###
# Extract meta tags info from your Seorelified Model
add_metatags @post
...
end
def history
...
end
end
In case of missing add_metatags
declaration in controller actions, you can define metatags through rails L10n
library. Simply by defining your locale strings for seorel.
For instance seorel.en.yml
:
# encoding: utf-8
en:
seorel:
# controller_name:
# action_name:
# prepend_title: '...'
# title: '...'
# append_title: '...'
#
# prepend_description: '...'
# description: '...'
# append_description: '...'
posts:
show:
prepend_title: "Details for: "
history:
title: "Posts history metatitle"
description: "Posts history metadescriprion"
tags:
index:
title: "Tag list"
description: "Tag list metadescription"
Where posts
and tags
are controller names, while history
and index
are their actions.
In your layout <head></head> section just call the render_meta_tags
helper:
<head>
<%= render_meta_tags %>
...
</head>
