<p>The databag system is a simple support system in Lektor that allows a
Lektor website to load variables from simple key/value or JSON files.
This is primarily useful to load translations, API keys and similar
things that are needed in multiple templates.</p>
<p>From within templates you can use the <a href="../templates/globals/bag/" class="ref">bag</a>
function to access databags.</p>
<h2 id="supported-formats">Supported Formats</h2><p>Databags go into the <code>databags/</code> folder in your project. There are two
formats supported: key/value pairs as ini files as well as JSON files:</p>
<table>
<thead><tr>
<th>Extension</th>
<th>Format</th>
</tr>
</thead>
<tbody>
<tr>
<td><code>.json</code></td>
<td>JSON</td>
</tr>
<tr>
<td><code>.ini</code></td>
<td>INI Files with or without sections</td>
</tr>
</tbody>
</table>
<h2 id="navigating-bags">Navigating Bags</h2><p>Dotted notation is used to navigate into data bags which are globally
merged together. This means that if you have a file named <code>i18n.ini</code>
with a section <code>[en]</code> and a key <code>CLICK_HERE</code> the path <code>i18n.en.CLICK_HERE</code>
will target that key. For JSON files further nesting is possible. You
can also just target a section and the return value will be a dictionary
which can for instance be used with the <a href="../templates/filters/tojson/" class="ref">tojson</a>
filter.</p>
<h2 id="example-databag">Example Databag</h2><p>This is a basic example of a data bag that contains configuration values
for google maps. It's stored in <code>databags/gmaps.ini</code>:</p>
2022-05-03 00:53:59 +02:00
<div class="hll"><pre><span></span><span class="na">key</span><span class="w"> </span><span class="o">=</span><span class="w"> </span><span class="s">1233456ABCDEFG</span><span class="w"></span>
2022-02-20 15:15:38 +01:00
<span class="na">api_url</span><span class="w"> </span><span class="o">=</span><span class="w"> </span><span class="s">https://www.google.com/maps/embed/v1/</span><span class="w"></span>
</pre></div>
<p>This can then be usde to good effect in templates:</p>
