I normally save new data to the database like this:
$this->MyTable->set(array(
'id' => $id,
'code' => $temp_code,
'status' => $status,
'age' => $age,
'location' => $location,
'money' => $money
));
$this->MyTable->save();
If the ID already exists in the database I update its corresponding fields like this:
$this->Adtweet->id = $id;
$this->Adtweet->saveField('code', $temp_code);
$this->Adtweet->saveField('status', $status);
Is there a better or 'proper' way to do this?
When I attempt to enter an ID that already exists and I use the set
function, I get the following SQL integrity error:
(Error: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '150245925' for key 'PRIMARY')
How can I write a function that cleanly handles duplicate entries without returning an error?
If you want to save new data, just use Model::save()
:
$data = array(
'ModelName' => array(
'foo' => $foo
)
)
// prepare the model for adding a new entry
$this->ModelName->create();
// save the data
$this->ModelName->save($data);
If you want to update your data just use the same method without calling Model::create()
$data = array(
'ModelName' => array(
'id' => $id
'foo' => $foo
)
)
$this->ModelName->save($data);
Edit:
I guess this is what you're looking for:
$this->ModelName->id = $id;
if (!$this->ModelName->exists()) {
$this->ModelName->create();
}
$this->ModelName->save($data);
Posted data example
Array
(
[ModelName] => Array
(
[column1] => value
[column2] => value
[column3] => value
)
)
Try this to add
if ($this->request->is('post')) {
$this->ModelName->create();
$this->ModelName->save($this->request->data);
}
Try this to edit
if ($this->request->is('post')) {
$this->ModelName->id = 2;
$this->ModelName->save($this->request->data);
}
