获取满足laravel方法的所有用户

I'm trying to get all the users where a given method in User model meets. Please see my code below:

User.php

public function isPicker(){
  return ($this->where('isPicker', 1)) ? true : false;
}

Now, I can use User::all();, but it returns all the users. What I want is to only return the users that meets the isPicker() method. What I'm trying to do in view is:

@foreach($users as $user)
  @if($user->isPicker())
    {{ $user->first_name }}
  @endif
@endforeach

This is also working fine, but it is not that efficient to use. What if there's a lot of method to check? Any idea for this?

Just do:

$users = User::where('isPicker', 1)->get();

Or create a scope:

public function scopeIsPicker($query)
{
    return $query->where('isPicker', 1);
}

// usage
$users = User::isPicker()->get();

Well you could change you code up a little to look like this.

@foreach($users->where('isPicker', 1)->all() as $user)
    {{ $user->first_name }}
@endforeach

But this will only work if the users var is a collection.

Other wise just change you query on how your getting the users to something like this.

User::where('isPicker', 1)->get()

Instead of checking in model file, you can directly query in your controller try below code

1. if you want to display only isPicker=1 users.

Controller Code :

$users = User::where('isPicker', 1)->get();

Blade code :

@foreach($users as $user)
    {{ $user->first_name }}
@endforeach

OR

2. if you want to display all users including isPicker 0&1.

Controller Code :

$users = User::all();

Blade code :

@foreach($users as $user)
  @if($user->isPicker == 1)
    {{ $user->first_name }}
  @else
    <p>Picker is 0</p>
  @endif  
@endforeach

Note : Remove your isPicker function from user model file because its unuse.
