Phoenix.Pagination
Simple pagination for Ecto and Phoenix using plaing EEx templates. It is based on a fork of Kerosene, we think that pagination markup should be handled in templates, rather than with helper functions. So, here it comes.
Installation
If available in Hex, can be installed as:
Add phoenix_pagination to your list of dependencies in mix.exs
:
def deps do
[{:phoenix_pagination, "~> 0.7.0"}]
end
Add Phoenix.Pagination to your repo.ex
:
defmodule MyApp.Repo do
use Ecto.Repo, otp_app: :testapp
use Phoenix.Pagination, per_page: 15
end
Usage
Start paginating your queries
def index(conn, params) do
{products, pagination} = Product
|> Product.with_lowest_price
|> Repo.paginate(params)
render(conn, "index.html", products: products, pagination: pagination)
end
Add view helpers to your view
defmodule MyAppWeb.ProductView do
use MyAppWeb, :view
import Phoenix.Pagination.HTML
end
Create your pagination template in lib/my_app_web/templates/pagination/pagination.html.eex
<%= pagination @conn, @pagination, [current_class: "is-current"], fn p -> %>
<nav class="pagination" role="navigation" aria-label="pagination">
<ul class="pagination-list">
<li><%= pagination_link p, :first, label: gettext("First"), class: "pagination-link", force_show: true %></li>
<%= for {pagenum, _, active} <- p.page_items do %>
<li><%= pagination_link p, pagenum, class: "pagination-link", current: active %></li>
<% end %>
<li><%= pagination_link p, :last, label: gettext("Last"), class: "pagination-link", force_show: true %></li>
</ul>
</nav>
<% end %>
You can have as many pagination templates as you want (even with custom filenames), and render it where you need:
<%= render MyAppWeb.PaginationView, "pagination.html", conn: @conn, pagination: @pagination %>
Building APIs or SPAs? no problem Phoenix.Pagination has support for Json.
defmodule MyAppWeb.ProductView do
use MyAppWeb, :view
import Phoenix.Pagination.JSON
def render("index.json", %{products: products, pagination: pagination, conn: conn}) do
%{data: render_many(products, MyAppWeb.ProductView, "product.json"),
pagination: paginate(conn, pagination)}
end
def render("product.json", %{product: product}) do
%{id: product.id,
name: product.name,
description: product.description,
price: product.price}
end
end
You can also send in options to paginate helper look at the docs for more details.
