locations_variable_generator.html (locations_array):

Create a javascript variable for use in the function adding map markers.

Accepts Liquid array object and converts it to a javascript list

of dictionaries (JSON). This will be used for chapters and events(posts) maps.

If array of posts (events) is provided we get the event's address, latitude,

longitude etc. from the FIRST sponsor object (if more than one are present

for an event) Sponsor is a equivalent of a foreignkey for the event.

One must remember though that sponsor is just a name not a reference to

the sponsor object.

This we find among sponsors using "where" filter as below.

This is to avoid duplication of records in our yml section.

Parameters:

locations_array: Liquid array

A Liquid array containing locations to convert to javascript array

of dictionaries. Can contain only 1 element.

Returns:

locations: JSON

Javascript array of dictionaries with locations' details.

Further info:

To generate an array:

{% assign chapters = "" | split: ',' %}

{% for chapter in site.chapters %}

{% assign chapters = chapters | push: chapter %}

{% endfor %}

But it should be enough to use site.chapters or site.posts etc.

var locations = [

{% for location in include.locations_array %}

{% if location.is_post %}

{% assign host_sponsor_id = location.sponsor %}

{% assign host_sponsor = site.sponsors | where:"obj_id", host_sponsor_id | first %}

{% capture prefix %}

"address": "{{ host_sponsor.address }}",

"lat": {{ host_sponsor.lat }},

"lng": {{ host_sponsor.lng }},

"address": "{{ location.address }}",
