This misunderstanding needs to be clarified in priority. One thing that any user will have to note is that Laravel find is not a query builder as it may look to be. Laravel Find is used to retrieve data with the help of primary keys that are available in Laravel. Most of the data in Laravel are auto-generated and they are self-coded as Laravel PHP helps in getting applications and websites ready faster with a lot of automated properties. With a load of too much data, it becomes difficult or even time-consuming to manually hunt for a specific set of records to work on. Laravel find is capable of retrieving data from the database for the user when the user needs to obtain a concerned set of data from a larger database. The results that are obtained with the help of the ‘find’ method are always limited to the record that is available and the object is returned in the form of a result. The SQL statement that is equivalent is the ‘SELECT FROM categories in which the WHEREid = 1 LIMIT 1. ‘Find’ method makes use of the primary key id that generally works by filtering for any particular record with the simple id value of 1. $c->find (1) works by calling the ‘find’ method on the user’s instance variable, which is $c which helps in returning a single record for the user.
Laravel also expects the id to be an integer if you are using something other than an integer (such as a string) you need to set the incrementing property on your model to false. If you have something set up like protected $primaryKey = foo_id the find() function will go through foo_id instead of id. If you have none set, it’s going to assume id. The find() method finds the Model by its $primaryKey property. When there is a need to retrieve any record with the help of the primary key use this code: $user = User::find (1)
Laravel eloquent find first software#
Get() is for lots of data and first() is for single data.Web development, programming languages, Software testing & others You have may Eloquent collection methods, for example you exists() method will return you boolean, if the database has query part or not. Whatever laravel get at first, it suddenly return that and this is very cool. Suppose you have two results from your query then which one will return by this function, so the answer is the first one. Ya this gives you only one result from the ocean of data but as the name suggest it will give the first result. When you want to get collection of data means, lots of results then use get but if you want to retrieve only one result then use first. When we have to use get() and when first() Get method give a collection and first method give you a model instance. Now consider these two codes and their resultsĪt first look you did't get the difference, but look closely there is a great difference.
Laravel eloquent find first code#
īut the question arise, what is the difference between these two and why that code was not working with get but worked perfectly with first. Then I go through the codes and found that he was using get method ( to get data from database via model) and that was the mistake, I just changed get to first. One of my friend called me and said, Hey Sarthak I need your help, I could't find out the problem in my code.
