如何连接到Heroku connect的表，该表在cake php in cake php v3.x中作为自定义字段创建

Question

I am trying to connect with Heroku connect table via CakePHP 3. For some reason, I get the following error when I try to connect with a table whom name ends in '__c'

 PHP Fatal error:  Call to a member function newEntity() on boolean

Previously, I solved fundamental connection problem that I had in CakePHP at Heroku Connect with Cakephp v3.0.12 form.

So I could connect with one that doesn't have '__c' in its table name. From the error msg, I understand for some reason my cake app failed to connect with the table I want to connect.

In my App/Model/Table/someFieldTable.php, I have

 public function initialize(array $config)
{
    parent::initialize($config);
    $this->table('salesforce.some_field__c');
    $this->displayField('name');
    $this->primaryKey('id');
}

I also have the following in my tableController.php

$somefield = $this->someField->newEntity();
   // variables are assigned to $somefield 
if($this->someField->save($someField)){
   // error handling here 
}

I am still new to CakePHP and Heroku connect. If anybody knows how to connect with these field (table) with postfix '__c' in CakePHP, Please help me.

Using the TableRegistry class is an effective answer, here is the correct method of getting the autowired table in the controller working:

As you've already been informed, your file naming scheme is incorrect, but that's not the full solution to your table name formatting with Heroku. Your entry within $this->table() should not be namespace to a database with a dot, as the database is appending via the current connection (which is most likely the default datasource defined in app.php) you are making queries on. The entire fix would consist of:

// 1. Change the file name to the correct scheme: SomeFieldTable.php

// 2. In order for the controller to autowire the table, you must correctly
// name the controller file as well: SomeFieldController.php

// 3. Change the table name within SomeFieldTable.php to the appropriate
// name: 'some_field_c'

public function initialize(array $config)
{
    parent::initialize($config);
    $this->table('some_field__c');
    $this->displayField('name');
    $this->primaryKey('id');
}

// 4. Finally, in the controller, the table is accessed via the camel capsed name

class SomeFieldController extends AppController
{
    public function getEndpoint()
    {
        $result_set = $this->SomeField->find()->all();
        $this->set('result_set', $result_set);
    }

    public function saveEndpoint()
    {
        $new_some_field = $this->SomeField->newEntity($this->request->data);
        if ($this->SomeField->save($new_some_field)) {
            $this->set('new_some_field', $new_some_field);
        } else {
            $this->set('errors', $new_some_field->errors());
        }
    }
}
