Laravel Subdomain Routing

The code above creates a route group that is only accessible from a subdomain. The subdomain is determined by the {username} parameter. In this example, if the user visits amirreza.workspace.com, they will see a message indicating which subdomain the request came from.

This can be useful for creating different experiences for different users in the same domain. For example, you could use subdomains to give each user their own workspace where they can manage their own data.

Laravel Get Latest Record

The code above is a repository method to get the last product created. This is useful if you want to display the most recently created product on your website, for example.

The code uses the Laravel query builder to order the products by id in descending order and then gets the first product from the resulting collection. You could also order the products by created_at in descending order, or use the latest() method to accomplish the same thing.

Laravel Eloquent Bulk Insertion

This Laravel code does a batch insertion, which means it will insert multiple records into the database simultaneously. This can be beneficial because it is faster than insertions are done one at a time, and it can also help to prevent race conditions.

Its benefit is that you can take multiple records and insert them into the database all at once, which can be helpful if you’re working with a lot of data.

One potential downside to batch insertion is that if there are any errors in the data, all inserts will fail. This can be mitigated by doing a batch insertion in smaller chunks so that if there is an error, only a smaller number of records will be affected.

Another downside is that if you are using an ORM like Laravel’s Eloquent, you will not be able to take advantage of features like automatic timestamping or event listeners/observers.

Laravel Eloquent to Raw SQL

With Laravel, you can take your Eloquent queries and convert them into raw SQL with bindings. This can be helpful if you need to debug your queries or if you need to work with a database that doesn’t have Eloquent support.

Here, we’ll show you how to convert an Eloquent query to raw SQL with bindings in Laravel:

This code is commonly used to debug a Laravel Eloquent query. It returns the SQL query and the parameters that are being used. This can be useful to see what is happening behind the scenes and to troubleshoot issues.

Laravel Eloquent If Record Exists

The Laravel Eloquent exists method is used to check if a given record exists in the database. In the example above, the code is checking if a user with a given email exists in the database. If a user with the given email exists, the code will return ‘exists’. If a user with the given email does not exist, the code will return ‘not exists’.

This method can be used in a variety of situations where you need to check if a given record exists in the database. For example, you could use it to check if a given email exists in a database of users before adding a new user to the database.

Laravel Eloquent Nested Wheres (AND OR)

The code above is a Laravel Eloquent nested wheres query in a repository class. This query will return all users who are active and either free or on call. This is useful for getting a list of users who are available to do work.

The first where clause checks if the user is active. The second where clause uses a nested query to check if the user is free or on call. This is done by checking the status and on_call columns. If either of these columns is true, the user will be included in the results.

Laravel Eloquent Random Order

The code above is a Laravel Eloquent code used to get a random user or multiple random users in a repository class. The use-case examples could be a website that wants to show a random user on the homepage or a lottery that wants to show multiple random users as the winners.

Laravel Eloquent is a powerful ORM (object-relational mapper) that makes working with database tables and queries very easy. In the example above, the inRandomOrder() method is used to order the results of the query randomly. The get() method is then used to execute the query and return the results. The limit() method is used to limit the number of results returned.

Laravel Eloquent where not null

This code uses the “whereNotNull” method on the “Product” model to query the database for all products that have a non-null value for the “description” column. This would be useful, for example, if you wanted to retrieve all products that have a description and then display them to the user.

The “whereNotNull” method is just one of many methods that are available on the “Eloquent” class in Laravel. This class provides a convenient way to query the database and perform CRUD operations on database records.

Factory Design Pattern with Laravel Example

Sometimes when you write code, you may run into the issue of reusing a class over and over again. The Factory Pattern will help you create objects that can be used to create objects of other classes. This pattern is typically used when a set of related classes have similar functionality but require different instantiation. With this pattern, you can use a single factory to produce an instance of each class in your project.
