I have a custom table in which I want to save data. I tried below different methods to save data in table.But cannot get success. Please check below methods :

Method 1 :

$model = $this->_objectManager->create('Namesapce\Modulename\Model\Test\Product');
$model->setRowId(1);
$model->setProductId(2048);
$model->save();

Method 2 :

$model = $this->_objectManager->create('Namesapce\Modulename\Model\Test\Product');
$data = ['row_id' => 1, 'product_id' => '2048'] ;
$model->setData($data);
$model->save();

For testing purpose I have manually insert data in table and then try to getcollection.

Strange thing is I can sucessfully get collection of data from table.but can not save. I also put above code in try catch but it always going in try. Not in catch.

Please take me out from this issue. Thank you.

You need to be using a resource model ModelFactory, rather than trying to create through the object manager.

Please Flush magento cache and try to save again if it's not work, then See your log folder and do some debugging in your module:

I had faced same problem when working on Magento2 CRUD. Never use Primary Key with model save() method.

Definately row_id will be primary key.

How to check we created the correct model , resource & collection class in magento.

In magento2 $this->_objectManager interface use for creating the model object.

$subscription = $this->_objectManager->create('path-to-model class');

Example: Abc\Hello\Model\Subscription.

Use get_class($subscription) method. This will show the full class path.
