I'm facing an issue with displaying array instances in a grid connected to a store with a model. The type property is set to 'auto' for the array in the model instance. How can I adjust the settings to show all the array instances correctly in the grid? Currently, I am only seeing [object:Object]. Please refer to the screenshot for more details:
If you wish to showcase array values in a grid column, you have the flexibility to create your own custom renderer within the columns configuration.
As an illustration, the following renderer function will present all items from an array with commas separating them:
columns: [
{
...
renderer: function(value){
return value.join(', ');
}
...
}
]
To display the values in an array in a column in an Ext.grid.Panel, you can simply add a renderer field with a .toString() method to the column. Here's an example:
Ext.create('Ext.grid.Panel', {
...
columns: [
{
text: 'Title',
dataIndex: 'somearrayrecord'
renderer: function(value) {
return value.toString();
}
},
],
...
});
By using the array.toString() method in JavaScript, the values in your array will be printed out in the column.
