passing a condition to Model.where to find records in rails

Question

I have an instance in a method that is like this

@existinguser = User.where("trial_account_made_by = !nil? ")

I want to return all users where the trial_account_made_by ( a column in users table) is not nil. How do I pass that to where?

Answer 1

尝试使用trial_account_made_by is not null因为：

@existinguser = User.where("trial_account_made_by is not null")

Answer 2

For Rails 4.x , use

@existinguser = User.where.not(trial_account_made_by: nil)

For Rails 3.x , use

@existinguser = User.where('trial_account_made_by is not null')
