Hello, I'm stuck trying to make a belongsToMany relation . I have the models Property and Attribute; and the Controller Properties.

The Properties Controller have this settings.

public $implement = [
    'Backend.Behaviors.FormController',
    'Backend.Behaviors.ListController',
    'Backend.Behaviors.RelationController',
];
public $relationConfig = 'config_relation.yaml';

The file config_relation.yaml

attributes:
    label: Attributes
    list: @/plugins/pronet/realestate/models/attribute/columns_relation.yaml

The file columns_relation.yaml

# ===================================
#  List Column Definitions
# ===================================
columns:
    name:
        label: pronet.realestate::lang.global.label.name
        searchable: yes
    slug:
        label: pronet.realestate::lang.global.label.slug
        searchable: yes
    in_search:
        label: pronet.realestate::lang.global.label.in_search
        searchable: false
        type: switch

In Controller partial properties/update.htm

<?= $this->relationRender('attributes'); ?>

In Property Model

public $belongsToMany = [
    'attributes' => ['Pronet\RealEstate\Models\Attribute', 'table' => 'pronet_realestate_property_attributes', 'primaryKey' => 'property_id', 'foreignKey' => 'attribute_id'],
 ];

I don't know what i'm missing, but when a click the button to add a new attribute, receive this message:

"SQLSTATE[42S22]: Column not found: 1054 Unknown column '' in 'field list' (SQL: select `` from `pronet_realestate_attributes` inner join   `pronet_realestate_property_attributes` on `pronet_realestate_attributes`.`id` = `pronet_realestate_property_attributes`.`attribute_id` where `pronet_realestate_attributes`.`deleted_at` is null and `pronet_realestate_property_attributes`.`property_id` = 1)" 

Any help will be appreciate. Thanks and sorry my english

I presume name, slug and in-search exist as fields in your attributes table?

These sort of problems are really difficult to diagnose because the form is ajax based. I would really like one of the helpers like Clockwork to be baked into October. I have tried to install them but because of the automatic updates of October (which works brilliantly by the way) instead of using composer that is not a great solution.

Thanks for your reply @axomat. I resolve the attributes relation making it manually, extending the Form Widget.

But now i found the some problem with another relation tables.
I'm writing a real estate plugin.And I have the models Property (like houses, condos, etc.), Transactions (like sale, rent, project, etc) , PriceType (like hi season, low season, January, etc), Currency (like dollar, euro, etc).

Them I have the relation $belongsToMany in Property model.

public $belongsToMany = [
  'transactions' => [
    'Pronet\RealEstate\Models\Transaction',
    'table' => 'pronet_realestate_property_transactions',
    'primaryKey' => 'property_id',
    'foreignKey' => 'transaction_id',
    'pivot' => ['value', 'price_type_id', 'currency_id'],
  ],
];

In Properties Controller

public $relationConfig = 'config_relation.yaml';

In config_relation.yaml

transactions:
    label: pronet.realestate::lang.properties.label.transactions
    list: @/plugins/pronet/realestate/models/transaction/columns.yaml
    emptyMessage: pronet.realestate::lang.properties.label.no_transactions
    defaultSort: name
    showSorting: false
    pivot:
      fields:
        value:
          label: pronet.realestate::lang.global.label.value
          type: text
        price_type_id:
          label: pronet.realestate::lang.global.label.price
          type: dropdown
          options: listPriceTypes
        currency_id:
          label: pronet.realestate::lang.global.label.currency
          type: dropdown
          options: listCurrencies 

In property/fields.yaml

# TAB TRANSACTIONS
    transactions:
      tab: pronet.realestate::lang.properties.label.transactions
      context: update
      type: partial
      path: @/plugins/pronet/realestate/controllers/properties/_form_transactions.htm

In _form_transactions.htm partial

<?= $this->relationRender('transactions'); ?>

The tab Transactions are rendered ok, like the next image:

But, when I click to add a new Transaction, I have this message:

Already been a week trying to solve this problem, but can not find any solution, using the CMS itself to generate the form of relationships.

Any help will be appreciated

Many thanks.

I also ran into the same issue. to fix the model add the following to your config_relations.yaml

form: @/plugins/dma/friends/models/step/fields.yaml
