Building the View DSL

Let’s first start by understanding what our view modules should look like. Let’s take a look at the following view module:

defmodule TasksWeb.TaskView do
  use Goldcrest.View
  def stringify_task(_task = {name, description}) do
    "#{name} - #{description}"
  end
end

In the preceding module, we have defined a helper function that converts a task to a string, which can be further used in a template as shown in the following code snippet:

<h1>Listing Tasks</h1>
<table>
  <thead>
    <tr>
      <th>Task</th>
      <th></th>
    </tr>
  </thead>
  <tbody>
  <%= for {task, index} <- Enum.with_index(@tasks) do %>
    <tr>
   ...
