< 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 >

< td > < code > .json< / code > < / 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 >
