When I use update() with find() and invalid id like
User::find(100)
->update(['is_valid' => true])
I got error:
Error: Call to a member function update() on null
But when I use update() with where and invalid id like
User::where('id', 100)
->update(['is_valid' => true])
It returns false as expected. so what is the problem when I use find()? How to solve it?
if you want to use
User::find(100)
->update(['is_valid' => true])
this without error you can use optional() helper like this
optional(User::find(100))
->update(['is_valid' => true])
ref link https://laravel.com/docs/8.x/helpers#method-optional
User::find(0) ---> null
it retrun model instance if data found and if not found it it null so you cannot chain ->update() on null that's why your getting error
User::where('id', 100) ----> eloquent instnace
it is a laravel Eloquent so here you can chain as many function which are avilable in eloquent
