MODX Revolution 2.7.0-pl
MIGX 2.12.0-pl

Objective

To replace (a manually updated) json file with a migxloopcollection to json output

Why?

I want the json to dynamically change every time the MIGXdb CMP is updated, currently I have to update the json every time an update is done to the CMP, so I'm trying to introduce a method to dynamically replace the manual update

What I Have Done That Is Working

I have set up a MIGXdb CMP where I can load and update data to the MySql database

MIGXdb Schema
<?xml version="1.0" encoding="UTF-8"?>
<model package="towersite" baseClass="xPDOObject" platform="mysql" defaultEngine="MyISAM" version="1.1">
    <object class="TowerSite" table="towersite" extends="xPDOSimpleObject">
	  	<field key="siteid" dbtype="varchar" precision="255" phptype="string" null="false" default=""/>
		<field key="state" dbtype="varchar" precision="255" phptype="string" null="false" default=""/>
    	<field key="township" dbtype="varchar" precision="255" phptype="string" null="false" default=""/>        
		<field key="address" dbtype="varchar" precision="255" phptype="string" null="false" default=""/>
		<field key="lat" dbtype="varchar" precision="255" phptype="string" null="false" default=""/>
        <field key="lng" dbtype="varchar" precision="255" phptype="string" null="false" default=""/>			
		<field key="towertype" dbtype="varchar" precision="255" phptype="string" null="false" default=""/>
		<field key="pos" dbtype="int" precision="10" phptype="integer" null="false" default="0"/>
		<field key="createdon" dbtype="datetime" phptype="datetime" null="true"/>
    <field key="createdby" dbtype="int" precision="10" attributes="unsigned" phptype="integer" null="false" default="0" />
    <field key="editedon" dbtype="datetime" phptype="datetime" null="true"/>
    <field key="editedby" dbtype="int" precision="10" attributes="unsigned" phptype="integer" null="false" default="0" />
		<field key="deleted" dbtype="tinyint" precision="1" attributes="unsigned" phptype="integer" null="false" default="0" />
		<field key="deletedon" dbtype="datetime" phptype="datetime" null="false" />
		<field key="deletedby" dbtype="int" precision="10" phptype="integer" null="false" default="0" />
    <field key="published" dbtype="tinyint" precision="1" attributes="unsigned" phptype="integer" null="false" default="0" />  
		<field key="publishedon" dbtype="datetime" phptype="datetime" null="false" />
		<field key="publishedby" dbtype="int" precision="10" phptype="integer" null="false" default="0" />
    <aggregate alias="CreatedBy" class="modUser" local="createdby" foreign="id" cardinality="one" owner="foreign"/>
    <aggregate alias="EditedBy" class="modUser" local="editedby" foreign="id" cardinality="one" owner="foreign"/>
    </object>
</model>


migxloopcollection code (this is the part I think I need help with)
[[!migxLoopCollection?
&packageName=`towersite`
&classname=`TowerSite`
&selectfields=`id,siteid,state,township,address,towertype,lat,lng`
&toJsonPlaceholder=`markers` 
]]
[[+markers]]


json code (the original - this can work independently & it is what I am trying to replace)
markers = [
   {
     "siteid": "BNK1001",
     "state": "Bangkok Metropolitan Area",
	 "township": "Thonburi",
	 "address": "21 de laetya street",
	 "towertype": "Rooftop",
	 "lat": 16.829394,
     "lng": 96.155004
   },
   {
     "siteid": "BNK1002",
     "state": "Bangkok Metropolitan Area",
	 "township": "Phra Khanong",
	 "address": "Block 5, 12 Old Khanong Road",
	 "towertype": "Rooftop",
	 "lat": 16.827123,
     "lng": 96.164543
   },
];


I delete the 'markers json' file so I can test the migxloopcollection method, but when I load the web page it does not display the map markers and in the page source code I can see the migxloopcollection is collecting the data but the console is saying "Uncaught ReferenceError: markers is not defined". (There is a 'leaflet js' file looking for the 'markers json')

Does anyone know what I'm doing wrong here and can advise corrective action?

[[!migxLoopCollection?
&packageName=`towersite`
&classname=`TowerSite`
&selectfields=`id,siteid,state,township,address,towertype,lat,lng`
&toJsonPlaceholder=`markers` 
]]
<script>markers = [[+markers]]</script>

I'm not sure it is the best method but it is now displaying the markers on the map.

Next I'm going to add styling via a myTpl]]> jimmyjazz Jan 04, 2019, 03:35 AM https://forums.modx.com/thread/104770/help-how-to-fix-migxloopcollection-to-json-not-working#dis-post-563431
