Rails 4 scope with multiple conditions
I want to show active users for 1 day.
Member Model and Scope:
time_range = (Time.now - 1.day)..Time.now
scope :active, -> { where(created_at: time_range, gold_member: true, registered: true) }
However, when I call
@member = User.active
Below is the error:
NoMethodError: undefined method `call' for #<User::ActiveRecord_Relation:0x07fe068>
Please advise.

It won't fix your mistake, but there will be a problem with how you define your scope. Before you do that, you are defining a local variable time_range
. But the problem is that you are defining it in the body of your class ActiveRecord
, so it will only be evaluated once in production when the class is loaded. You have to evaluate your time range inside the lambda:
scope :active, -> {
where(created_at: (Time.now - 1.day)..Time.now, gold_member: true, registered: true)
}
