The `AddDate` function takes three arguments in logical order of `years`, `months`, and `days`.
|
|
|
|
## Example: Randomized Tweets from the Last 2 Years
|
|
|
|
Let's assume you have a file at `data/tweets.toml` that contains a list of Tweets to display on your site's homepage. The file is filled with `[[tweet]]` blocks; e.g.---
|
|
|
|
{{< code-toggle file="data/tweets" >}}
|
|
[[tweet]]
|
|
name = "Steve Francia"
|
|
twitter_handle = "@spf13"
|
|
quote = "I'm creator of Hugo. #metadocreference"
|
|
link = "https://twitter.com/spf13"
|
|
date = "2017-01-07T00:00:00Z"
|
|
{{< /code-toggle >}}
|
|
|
|
Let's assume you want to grab Tweets from the last two years and present them in a random order. In conjunction with the [`where`](/functions/where/) and [`now`](/functions/now/) functions, you can limit our range to the last two years via `now.AddDate -2 0 0`, which represents a point in time 2 years, 0 days, and 0 hours before the time of your last site build.
|
|
|
|
{{< code file="partials/templates/random-tweets.html" download="tweets.html" >}}
|
|
{{ range where $.Site.Data.tweets.tweet "date" "ge" (now.AddDate -2 0 0) | shuffle }}
|
|
<div class="item">
|
|
<blockquote>
|
|
<p>
|
|
{{ .quote | safeHTML }}
|
|
</p>
|
|
— {{ .name }} ({{ .twitter_handle }}) <a href="{{ .link }}">
|
|
{{ dateFormat "January 2, 2006" .date }}
|
|
</a>
|
|
</blockquote>
|
|
</div>
|
|
{{ end }}
