Question

I’m trying to update some data in database but I’m getting this error:

undefined method `is_current' for #<ActiveRecord::Relation:0x38622a8>

My controller:

@user = User.where("user_id = #{user_id} and is_current = 1") 

if @user.nil?
  puts"xxxxxxxxxxxxxxxxxxxxxxxxxxx"
else 
  @user.is_current = 0
  @user.to = Time.now
  @user.save
end

User.where returns an array. You need to say .first afterwards. Additionally do not use a string in where with out escaping your arguments. Your query is not secure and is open to SQL injection.

@user = User.where(user_id: user_id, is_current: 1).first
