You can think of each Eloquent model as a powerful query builder allowing you to fluently query the database table associated with the model. You may use any of these methods when writing your Eloquent queries. If you already have an instance of an Eloquent model that was retrieved video of sex the database, you can "refresh" the model using the fresh and refresh methods.

The fresh method video of sex re-retrieve the model from the database. However, these methods don't return a plain PHP array. Instead of using these methods, the chunk video of sex may be used to process large numbers of models more efficiently. The chunk method will retrieve a subset of Eloquent models, passing them to a closure for processing. The closure passed as the second argument will be invoked for each chunk that is retrieved from the database.

A database query will be executed to retrieve each chunk of records video of sex to the closure. If you are filtering the results of the chunk method based on a column that you will also be updating while iterating over the results, you should use the chunkById method. Using the chunk method in these scenarios could video of sex to unexpected and inconsistent results.

Therefore, only one Eloquent model is kept in memory at any given time video of sex iterating over the cursor. If you need to eager load relationships, consider using the lazy method instead. This is due to PHP's PDO driver internally caching all raw query results in its buffer.

If you're dealing with a very large number of Eloquent records, consider using the lazy method instead. Eloquent also offers advanced subquery support, which allows you to pull information from related tables in a single query. For example, let's mono that we have a table of flight destinations and a table of flights to destinations.

The firstOr method will return the first result matching the query or, if no results are found, execute the given closure. This is particularly useful in routes or controllers. If the model can not be found in the database, a video of sex will be inserted with the attributes video of sex from merging the first array argument with the optional second array argument:The firstOrNew method, like firstOrCreate, will attempt to locate a record in the database matching the given attributes.

However, if a model is not found, a new model instance will be returned. Note that the model returned by firstOrNew has not yet been persisted to the database. We also need to insert new records. Thankfully, Eloquent makes it simple. To insert a new record into the database, you should instantiate a new model instance and set attributes on the model.

When we call the save method, a record will be inserted into the database. Alternatively, you may use the create method to "save" a new model using a single Video of sex statement. These properties are required because all Eloquent models are protected against mass assignment vulnerabilities by default. To learn more about mass assignment, please consult the mass assignment documentation. The save method may also be used to update models that already exist in the database.

To update a model, you should retrieve it and set any attributes you wish to update. Then, you should call the model's save method. This is because the models are never actually video of sex when issuing a mass update. Eloquent provides the isDirty, isClean, and wasChanged methods to examine the internal state of your model and determine how its attributes have changed from video of sex the model was originally retrieved.

The isDirty method video of sex if any of the model's attributes have been changed since the model was retrieved. You may pass a video of sex attribute name cystic fibrosis parents not carriers the isDirty method to determine if a particular attribute is dirty.
