## Usage
```ruby
class Category < ActiveRecord::Base
include MetaManager::Taggable
end
@category = Category.new
@category.tag_title = 'category test title'
@category.tag_keywords = "Some keywords"
@category.tag_description = "Some description"
@category.meta_tags.build(:name => "og:title", :content => 'category og:title')
# create dynamic meta tags, who will be overwrited the same category tag names
# only with @meta_dynamic=true in controller
@category.meta_tags.build(:name => "og:title", :content => 'dynamic og:title - %{post.title}', :is_dynamic => true)
@category.meta_tags.build(:name => "title", :content => '%{post.title} - %{post.notes}', :is_dynamic => true)
@category.save
# create post for dynamic example
@post = Post.create(:title => 'post test title', :notes => 'post test notes')
```
## Rendering example
At layouts/application.html.erb
```html
<%= raw(render_meta_tags(@category)) %>
<%= render_page_title(@category) %>
```
At controllers/posts_controller.rb
```ruby
before_action :find_category
before_action :prepare_dynamic_page, :only => [:show]
def index
@posts = Post.order('id')
respond_with(@posts)
end
def show
@post = Post.find(params[:id])
respond_with(@post)
end
protected
def find_category
@category = Category.first
end
# set @meta_dynamic true to turn on dymanic meta tags.
def prepare_dynamic_page
@meta_dynamic = true
end
```
It will be generate meta tags and title for @category.
In action show we wont to generate dynamic meta tags from instance @post.
It means that meta tag 'og:title' and tag 'title' will be overwrited with attributes from instance @post.
### Results
Action index:
```html
category test title
```
Action show:
```html
post test title - post test notes
```
## Test
```
rake test
```
