Agile Web Development with Rails 6: Prose does not match code (P1.0 PDF pp. 179)
Page 179 contains the following code snippet:
<%= form_with(model: order, local: true) do |form| %>
<p>
<%= form.label :name, "Name:" %>
<%= form.text_field :name, size: 40 %>
</p>
<% end %>
In the paragraph following the code snippet, the 3rd sentence contains a typo. It should be corrected as follows:
The first argument,
module: ordermodel: order, tells the helper which instance variable to use when naming fields and sending the form data back to the controller.
