Iterating
This document only applies when using https://github.com/gobuffalo/buffalo/render.
Please see github.com/gobuffalo/plush for more details on the underlying templating package.
Iterating Through Arrays
When looping through arrays
or slices
, the block being looped through will have access to the "global" context.
The for
statement takes 1 - 2 arguments. When using the two argument version, the first argument is the "index" of the loop and the second argument is the value from the array or slice.
<ul>
<%= for (index, name) in names { %>
<li><%= index %> - <%= name %>
<% } %>
</ul>
When using the one argument version the index is omitted and just the value is returned:
<ul>
<%= for (name) in names { %>
<li><%= name %>
<% } %>
</ul>
Iterating Through Maps
Looping through maps
using the each
helper is also supported, and follows very similar guidelines to looping through arrays
.
When using the two argument version, the first argument is the key of the map and the second argument is the value from the map:
<ul>
<%= for (key, value) in users { %>
<li><%= key %> - <%= value %>
<% } %>
</ul>
When using the one argument version the key is omitted and just the value is returned:
<ul>
<%= for (user) in users { %>
<li><%= user %>
<% } %>
</ul>
