Rails adds include_seconds option to datetime_field.


Previously, to exclude seconds from datetime, we had to parse datetime using strftime.

Before

Let’s say we have a Product model and we need to show purchased_at as a date time field excluding seconds.

This is our ProductsController.

  class ProductsController < ApplicationController
    def show
      @product = Product.find(params[:id])
      render :show
    end
end

And this is how our views/products/show.html.erb would look like.

  <h1>Product Detail</h1>

  <table class="table table-hover">
  <tbody>
    <tr>
      <%= form_with model: @product do |form| %>
        <%= datetime_field("product", "purchased_at", value: @product.purchased_at.strftime("%Y-%m-%dT%H:%M")) %>
      <% end %>
    </tr>
  </tbody>

</table>

And this is how it will get rendered on the browser.

After

Now, Rails allows adding a include_seconds option to datetime_field, using which we can include/exclude the seconds.

  <h1>Product Detail</h1>

  <table class="table table-hover">
  <tbody>
    <tr>
      <%= form_with model: @product do |form| %>
        <%= datetime_field("product", "purchased_at", include_seconds: false) %>
      <% end %>
    </tr>
  </tbody>

</table>

This is how a browser renders it.

And suppose we need to include the seconds, we can pass include_seconds as true.

  <h1>Product Detail</h1>

  <table class="table table-hover">
  <tbody>
    <tr>
      <td>
      <%= form_with model: @product do |form| %>
        <%= datetime_field("product", "purchased_at", include_seconds: true) %>
      <% end %>
    </tr>
  </tbody>

</table>
