If the table has date field  this User  orderBy  created at    desc  - gt first     is the best solution  I think  But there is no date field  Model   orderBy  id    desc  - gt first  - gt id  is the best solution  I am sure

Don t use Model  latest  - gt first    because if your collection has multiple rows created at the same timestamp  this will happen when you use database transaction DB  beginTransaction    and DB  commit    then the first row of the collection will be returned and obviously this will not be the last row  Suppose row with id 11  12  13 are created using transaction then all of them will have the same timestamp so what you will get by Model  latest  - gt first    is the row with id  11

You ll need to order by the same field you re ordering by now  but descending  As an example  if you have a time stamp when the upload was done called upload time  you d do something like this   For Pre-Laravel 4  return DB  table  files  - gt order by  upload time    desc  - gt first      For Laravel 4 and onwards  return DB  table  files  - gt orderBy  upload time    desc  - gt first      For Laravel 5 7 and onwards  return DB  table  files  - gt latest  upload time  - gt first      This will order the rows in the files table by upload time  descending order  and take the first one  This will be the latest uploaded file

You never mentioned whether you are using Eloquent  Laravel s default ORM or not  In case you are  let s say you want to get the latest entry of a User table  by created at  you probably could do as follow   User  orderBy  created at    desc  - gt first      First it orders users by created at field  descendingly  and then it takes the first record of the result   That will return you an instance of the User object  not a collection  Of course  to make use of this alternative  you got to have an User model  extending Eloquent class  This may sound a bit confusing  but it s really easy to get started and ORM can be really helpful   For more information  check out the official documentation which is pretty rich and well detailed

Use the latest scope provided by Laravel out of the box   Model  latest  - gt first      That way you re not retrieving all the records  A nicer shortcut to orderBy

User · Answer

be aware that last    latest   are not deterministic if you are looking for a sequential or event ordered record  The last recent records can have the exact same created at timestamp  and which you get back is not deterministic  So do orderBy id foo - gt first    Other ideas suggestions on how to be deterministic are welcome

User · Answer

You can use the latest scope provided by Laravel with the field you would like to filter  let s say it ll be ordered by ID  then   Model  latest  id  - gt first      So in this way  you can avoid ordering by created at field by default at Laravel

If you are looking for the actual row that you just inserted with Laravel 3 and 4 when you perform a save or create action on a new model like    user- gt save      -or-   user   User  create array  email    gt   example gmail com       then the inserted model instance will be returned and can be used for further action such as redirecting to the profile page of the user just created   Looking for the last inserted record works on low volume system will work almost all of the time but if you ever have to inserts go in at the same time you can end up querying to find the wrong record  This can really become a problem in a transactional system where multiple tables need updated
