#Laravel check no results from eloquent find code#
I highly recommend you check out the source code for the Collection class, it's pretty simple. If you're not sure what class you're actually working with, try doing var_dump(User::all()) and experimenting to see what classes it's actually returning (with help of get_class(.)). So at that time, returns ModelNotFoundException exception as response. There is that if you want to fetch data from laravel model and data is not found in database. Those methods also exist on the Collection object, which can get returned from the Query Builder if there are multiple results. Sometimes, you are building a restful API in laravel and you find No query results for the model App\User, App\Pruduct, etc, This type of error comes in one condition. when you call certain methods like ->all() ->first() ->lists() and others). The Query Builder essentially builds a query until you call a method where it will execute the query and hit the database (e.g. For that reason it can be confusing to know what one you’re working on. The Collection and the Query Builder differences can be a bit confusing to newcomers of Laravel because the method names are often the same between the two.
You can use SQL and wildcard into Laravel to get matched results. count($result) works because the Collection implements Countable and an internal count() method: TThe LIKE query is used in a WHERE clause to search for a specified pattern in a column.In this article, I will show a few different examples of what to watch out for, including the cases when the problem is 'hidden' in unexpected places in the code. results retrieved via the get method or accessed via a relationship.
A big part of that is a so-called 'N+1 Query Problem'. All Eloquent methods that return more than one model result will return instances. This is useful if you need or are expecting only one result from the database. Eloquent performance is typically the main reason for slow Laravel projects. You could also use ->first() instead of ->get() on the query builder which will return an instance of the first found model, or null otherwise. When using ->get() you cannot simply use any of the below: if (empty($result))
