Disallow deletion of record based on value.

[rinorway]

Reading the example of https://docs.espocrm.com/development/dynamic-handler/ does anyone know how to disable deletion of a record based on a field value ?

Even if you cannot protect a record from deletion, at least the UI would not allow it.

Eg: "Deletion of the person with name "Queen" is not allowed".

Any other suggested mechanism would be welcome.

Using the example in the documentation you could write something like this in the script
client/custom/src/account-dynamic-handler.js

    controlFields: function () {
        if (this.model.get('name') === "Queen") {
            this.recordView.removeButton('delete');
        }
     },

You can see a more elaborate example of using dynamic handler in this post. https://forum.espocrm.com/forum/deve...gic-conditions

The above will hide the delete button in detail view.

I don't think that it's possible to remove the "remove" row option in list view for a specific row, but if you want to remove the "remove" option in list view (row options) for all records you can follow these steps:

1) Create custom view: client/custom/src/views/record/list.js

define('custom:views/record/list', 'views/record/list', function (Dep) {

    return Dep.extend({

        rowActionsView: 'views/record/row-actions/view-and-edit',

    }

}

2) Edit your entity's clientDefs to let Espo know that a custom view needs to be used when rendering a list of records for this entity:

{
    "recordViews": {
        "list" : "custom:views/record/list"
    }

}
