How to create an editable listbox column in a MIGX grid?

I have a listbox type formtab working just fine, it adds/edits etc from the popup form:

{
          "MIGX_id":52,
          "field":"category",
          "caption":"Category",
          "description":"",
          "description_is_code":"0",
          "inputTV":"",
          "inputTVtype":"listbox",
          "validation":"required",
          "configs":"",
          "restrictive_condition":"",
          "display":"",
          "sourceFrom":"config",
          "sources":"",
          "inputOptionValues":"@EVAL return 'Choose Category==||' . $modx->runSnippet('migxLoopCollection',array('packageName'=>'projects','classname'=>'ProjectCategory','tpl'=>'@CODE:[[+category]]==[[+id]]','outputSeparator'=>'||'));",
          "default":"",
          "useDefaultIfEmpty":"0",
          "pos":3
        },

So you can see it's getting it's options from a database table:

<object class="ProjectCategory" table="bigblock_project_category" extends="xPDOSimpleObject">
        <field key="category" dbtype="char" precision="50" phptype="string" null="false" />   
        <field key="sort" dbtype="int" precision="10" phptype="integer" null="false" default="0" /> 
        <aggregate alias="Project" class="Project" local="id" foreign="category" cardinality="many" owner="local" default="0" />   
    </object>

this works great - shows the options - everything is happy.

Now, I found a couple articles & posts on how to render the name of the category (rather than it's id) in the migx grid view column, seems straight forward.

HOWEVER:

I need the Category in the grid column view to be a listbox (select field) that is editable from the grid.

How is that done?

**UPDATE**
So somehow this is now "kind of" working if I use the joined class_field as the column field name, and it shows the category name in the grid view - great... HOWEVER, if I click/double click on the item the drop down list is blank. If I change "dataIndex":"ProjectCategory_category", to "dataIndex":"category", the drop down list is correctly populated AND I can change/edit the items (and verify they are correct in the database)

{
      "MIGX_id":13,
      "header":"Project Category",
      "dataIndex":"ProjectCategory_category",
      "width":"",
      "sortable":true,
      "show_in_grid":1,
      "customrenderer":"",
      "renderer":"",
      "clickaction":"switchOption",
      "selectorconfig":"",
      "renderchunktpl":"",
      "renderoptions":"",
      "editor":"this.listboxEditor"
    },

So one step further, all I need now is to know how to render the category name correctly AND have the listbox correctly populated. [ed. note: sean69 last edited this post 5 years, 10 months ago.]

Change field key "category" in DB, for example on "sub_category".

<object class="ProjectCategory" table="bigblock_project_category" extends="xPDOSimpleObject">
    <field key="sub_category" dbtype="char" precision="50" phptype="string" null="false" />   
    <field key="sort" dbtype="int" precision="10" phptype="integer" null="false" default="0" /> 
    <aggregate alias="Project" class="Project" local="id" foreign="category" cardinality="many" owner="local" default="0" />   
</object>

And accordingly change "[[+category]]" here:

"inputOptionValues":"@EVAL return 'Choose Category==||' . $modx->runSnippet('migxLoopCollection',array('packageName'=>'projects','classname'=>'ProjectCategory','tpl'=>'@CODE:[[+sub_category]]==[[+id]]','outputSeparator'=>'||'));",

And finally

    {
      "MIGX_id":13,
      "header":"Project Category",
      "dataIndex":"category",
      "width":"",
      "sortable":true,
      "show_in_grid":1,
      "customrenderer":"",
      "renderer":"this.renderChunk",
      "clickaction":"",
      "selectorconfig":"",
      "renderchunktpl":'[[migxLoopCollection? &packageName=`projects` &classname=`ProjectCategory` &where=`{"id":"[[+category]]"}` tpl=`@CODE:[[+sub_category]]`]]',
      "renderoptions":"",
      "editor":"this.listboxEditor"
    },

And don't forget to rename the field "category" to "sub_category" in the table "bigblock_project_category".

I actually did solve this by using a chunk in the renderchunk template for the category column:

[[!projects? &function=`getListBoxOption` &alias=`ProjectCategory` &object_id=`[[+ProjectCategory_id]]`php &return=`category`]]

It just calls a snippet that loads my projects class & passes the scriptproperties to it...

public function getListBoxOption($scriptProperties){

	$output = '';

	$alias = (isset($scriptProperties['alias'])) ? $scriptProperties['alias'] : FALSE;

	$object_id = (isset($scriptProperties['object_id'])) ? $scriptProperties['object_id'] : FALSE;

	$return_column = (isset($scriptProperties['return_column'])) ? $scriptProperties['return_column'] : FALSE;

	if(!$alias || !$object_id || !$return_column){ 
		return 'Missing object parameters.'; 
	}

	$option = $this->modx->getObject($alias, $object_id);

	if($option){

		return $option->get($return_column);

	}else{
		return ' No options found.';
	}

	 return;

}
