Cakephp一次保存多个记录

Question

Is it possible to use save more then one record in cakephp using the $this->save(); function?

Answer 1

save() is used to simply save a model:

Array
(
    [ModelName] => Array
    (
        [fieldname1] => 'value'
        [fieldname2] => 'value'
    )
)

Assuming the above information was stored in an array called $data, one would call

    $this->ModelName->save($data);

in order to INSERT a record into the model's table (if id field is not specified) or UPDATE a record of the model's table (if id field is specified).

saveAll() is used to:

Save multiple records of a model

Array
(
    [Article] => Array
    (
        [0] => Array
        (
            [title] => title 1
        )
        [1] => Array
        (
            [title] => title 2
        )
    )
)       

So, you may save many models at the same time instead of looping and using save() each time.

Save related records of a model

Array
(
    [User] => Array
    (
        [username] => billy
    )
    [Profile] => Array
    (
        [sex] => Male
        [occupation] => Programmer
    )
)

This would save both User and Profile models at the same time. Otherwise, you would have to call save() for User first, obtain the id of the newly saved user and then save Profile with user_id set to the obtained id.
