Dynamic field values: enum, multi-enum, etc.

That's awesome. Thanks for the effort and link.

You're welcome.

Here's the link for the Chats extension: https://payhip.com/b/tq62X

It is tested up to 7.1.11 only because I don't want to invest time in trying to make it work with 7.2 until that version is mature enough and the field validation bugs have been fixed, but it should work even with 7.2 on its current state.

Wait, a chat extension? Did you release this or is it internal/private? Either way, that's a cool idea and thank you for the code. That is exactly what I want to do.

Here's a sample of using an Ajax (API) call to load a multi-enum field with a list of roles, that I use in the Chats extension:

        setupOptions: function () {
            Espo.Ajax.getRequest('Role/action/list').then(
                function (data) {
                    data.list.sort((a, b) => (a.name > b.name) ? 1 : -1);
                    this.params.options = [];
                    data.list.forEach(function(optionObj){
                        // skip non-user roles for internal chat notifications
                        if(this.name.indexOf('privateChat') > -1 && (optionObj.userPermission === 'no' || optionObj.userPermission === 'not-set') ) {
                            return;                            
                        }
                        this.params.options.push(optionObj.name);                        
                    },this);
                    // update the field display after downloaing the options from the database
                    this.reRender();
                }.bind(this)
            );
        }
​

Here's another sample of loading a multi-enum with the names of the fields defined in an entity's list layout. This from the Grouped Records extension:

        setup: function() {
            Dep.prototype.setup.call(this);
            // halt processing to allow the layout manager call to generate a response
            this.wait(true);
            this.setupOptions();
        },

        setupOptions: function () {
            // use the 'list' layout to determine the fields that can be chosen to filter the collection
            this._helper.layoutManager.get(this.model.get('entityType'), 'list', (listLayout) => {
                let layoutArray = [];
                listLayout.forEach(function(field){
                    layoutArray.push(field.name);
                });
                this.params.options = layoutArray;
                this.wait(false);
            },this);  
        }

Hello bandtank

Yes it is possible to determine the options offered in an enum or multi-enum field via javasript coding.

To see an actual example, check this code: https://github.com/espocrm/espocrm/b...pe-list.js#L41

There you can see how the options for the multi-enum field entity-type-list are populated by fetching a list of scopes defined in metadata.

Don't forget though, if you are using Espo 7.2, that the field validation "enhancement", will throw an error unless the metadata "options" definition for your field is set to null.

This helps a lot. Thanks. I will make an API call to get the list of multi-enum options instead of fetching the values from metadata. It's basically the same thing, though.

Hi, not sure what do you mean by dynamic values other than links (probably that "opportunity" link is actually "opportunityId" and "opportunityName" field behind the scenes) ?

[bandtank]

Is it possible to provide dynamic values for fields other than links? Being able to provide a dynamic list of options for an enum or multi-enum field, for example, would be very useful in my environment.
