Using Umbraco And Getting Started

Umbraco 9

Im generating datatypes pragmatically (Quicker and easier to maintain accross multiple websites)

using umbraco 11.1.0

but I have an issue where I have created some custom property editors. They show up fine in the back end of the website if you create a datatype manually.

However in generation code for my datTypes I have a line

var editor = _dataTypeService.GetByEditorAlias(docType).FirstOrDefault();

is meant to get the propertyEditor the given alias. however it returns a null there is no dataType with this alias already created.

but If I create a dataType with a the given property editor as named anything. This code finds the property editor via the alias.

Not I have checked and checked and checked the Aliase names match etc. not code works if there is a least 1 dataType that uses this propertyEditor alias.

It is like you have 2 lists

List "A" contains all the possable propertyEdits available and this is the list that we see in the backoffice when creating dataTypes manually.

Then there is List "B" that contains al thepropertyEditors that have been used at least once.

so list B is smaller than List A but the code above searchs list B but it should be searching list A

full code

public void CreateDataType(int containerId, string name, string docType, Dictionary<string, object> preValues)
        {
            var exists = _dataTypeService.GetDataType(name);
            if (exists == null)
            {
                var editor = _dataTypeService.GetByEditorAlias(docType).FirstOrDefault();
                if (editor != null)
                {

                    DataType newDataType = new DataType(editor.Editor, _serializer, containerId);

                    newDataType.Name = name;

                    _dataTypeService.Save(ConfigureDataType(newDataType,docType,preValues));
                    int newDataTypeId = newDataType.Id;
                }
            }
            else
            {
                DataType created = (DataType)_dataTypeService.GetDataType(name);

                _dataTypeService.Save(ConfigureDataType(created, docType, preValues));
            }
        }

ConfigureDataType handles the different prevalue types.

Hi Daniel,

If you do _dataTypeService.GetAll() does it appear in the results?

Tried that. But no it doesnt come up in the list.

temporarily got round it by passing

_install.CreateDataType(formPickerId, "IBD Advanced Form Template Block Picker", "IBD.BlockMultinodePicker", preValues, new BlockMultinodePickerEditor(_ioHelper, _dataValueEditorFactory, _editorConfigurationParser, EditorType.PropertyValue));

Editor decleared

[DataEditor(
        alias: "IBD.BlockMultinodePicker",
        type: EditorType.PropertyValue,
        name: "Block Multinode Picker",
        view: "/umbraco/backoffice/Plugins/IBDStarterKitBackoffice/BlockMultinodePicker",
        HideLabel = false,
        ValueType = ValueTypes.Json,
        Group = "Common",
        Icon = "icon-fa-b-linode color-deep-orange")]
    public class BlockMultinodePickerEditor : DataEditor
    {
        private readonly IIOHelper _ioHelper;
        private readonly IEditorConfigurationParser _editorConfigurationParser;

        public BlockMultinodePickerEditor(
            IIOHelper ioHelper,
            IDataValueEditorFactory dataValueEditorFactory,
            IEditorConfigurationParser editorConfigurationParser,
            EditorType type = EditorType.PropertyValue)
            : base(dataValueEditorFactory, type)
        {
            _ioHelper = ioHelper;
            _editorConfigurationParser = editorConfigurationParser;
        }
        protected override IConfigurationEditor CreateConfigurationEditor() => new BlockMultinodePickerConfigurationEditor(_ioHelper, _editorConfigurationParser);
    }

then inside routine did this

    public void CreateDataType(int containerId, string name, string docType, Dictionary<string, object> preValues, IDataEditor newEditor)
    {
        var exists = _dataTypeService.GetDataType(name);
        if (exists == null)
        {
            DataType newDataType = newEditor == null ? new DataType(_dataTypeService.GetByEditorAlias(docType).FirstOrDefault().Editor, _serializer, containerId) : new DataType(editor: newEditor, _serializer, containerId);

            newDataType.Name = name;

            _dataTypeService.Save(ConfigureDataType(newDataType,docType,preValues));
            int newDataTypeId = newDataType.Id;
        }
        else
        {
            DataType created = (DataType)_dataTypeService.GetDataType(name);

            _dataTypeService.Save(ConfigureDataType(created, docType, preValues));
        }
    }

line in question is from above

DataType newDataType = newEditor == null ? new DataType(_dataTypeService.GetByEditorAlias(docType).FirstOrDefault().Editor, _serializer, containerId) : new DataType(editor: newEditor, _serializer, containerId);

this replaced the code in the question above.

works from the perspective that the dataTypes that are not working are my new ones that have never been used therefore it i pass the into newEditor the IDataEditor it uses that and it works and if its a standard umbraco editor or another editor that I havent found the model for and pass it as a null it works as long as there is a property editor thathas been already created.

in looking into it deep I established that

var editor = _dataTypeService.GetByEditorAlias(docType).FirstOrDefault();

finds the first Data Type that exists and using that to create the new one. Its not finding the Property Editor by that alias.

with the work around both these work

        _install.CreateDataType(formPickerId, "IBD Advanced Form Block Settings", "Umbraco.BlockList", preValues, null);

        _install.CreateDataType(formPickerId, "IBD Advanced Form Template Block Picker", "IBD.BlockMultinodePicker", preValues, new BlockMultinodePickerEditor(_ioHelper, _dataValueEditorFactory, _editorConfigurationParser, EditorType.PropertyValue));

not ideal solution as if the Property has not been used yet and I dont noe the model then it will fail.

its like I should be looking for something like

_dataTypeService.GetDataEditorByAlias("IBD.BlockMultinodePicker").FirstOrDefault();

but it doesn't exist.

Hope this makes sense
