#4 Use Query to get CSV Data from a File Configured in Settings

Example from CSV which was uploaded as an App Setting

This is similar to the previous example, except that the CSV file can be uploaded again and again in the App-Settings UI. So the path isn't hard-coded.


@{
  // get the query
  var query = App.Query["ProductsFromCsvInAppSettings"];

  // get the data from the query
  var products = AsList(query);

  // get the current author (if available) from the stream Current
  var current = AsList(query["Current"]).FirstOrDefault();
}
<ul>
  @foreach(var product in products) {
    <!-- this li will have class=selected if it's the current one -->
    <li class='@(product == current ? "selected" : "")'>
      <!-- this creates a link to the current tutorial (data220) and product=id -->
      <a href='@Link.To(parameters: "data231=true&product=" + product.EntityId)'>
        @product.Name (#@product.Id)
      </a>
      @if(current == product) {
        <br>
        <em>
          @current.Description 
          (<a href="@product.Link" target="_blank">find out more</a>)
        </em>
      }
    </li>
  }
</ul>
