I have a simple form with an input for fee which is an integer. I want the input to be stored like money/prices are normally - to 2 decimal places - regardless of the input. If someone enters 5.1 into the form, I'd like it to show 5.10 in my view, for example. At the moment if I enter 5.1 it shows 5. Regardless of what is entered into the form a whole number is returned.

Here is the _form code:

<%= simple_form_for @order do |f| %>

<%= f.input :start_point %>
<%= f.input :restaurant_location %>
<%= f.input :customer_location %>
<%= f.input :fee %>
<%= f.button :submit %>

<% end %>

and here is the code from my index view:

<% @orders.each do |order| %>
 <h4 class="order-info"><%= order.start_point %></h4>
 <h4 class="order-info"><%= order.restaurant_location %></h4>
 <h4 class="order-info"><%= order.customer_location %></h4>
 <h4 class="order-info"><%= order.fee %></h4>
 <%= link_to "Edit", edit_order_path(order) %>
 <%= link_to "Delete", order_path(order), method: :delete, data: confirm: "Are you sure?" %>
<% end %>

If I write it as '%.2f' % order.fee it shows 5.00 in the view instead of 5.10

It looks like your are storing your value in integer datatype you can change it in float to store and show values after decimal point write following migration and add following line to change the datatype in your migration.

rails g migration change_fee_to_be_float_in_orders

and in your migration

class ChangeFeeToBeFloatInOrders
 def up
 change_column :orders, :fee, :float
 end

 def down
 change_column :orders, :fee, :integer
 end
end
