Pluck with condtions in rails

I want to compare a param extracted from a link to the list of data present in column... I am using pluck to generate a array of list(in controller) but not getting any success in comparing it

any method that I can fetch records in model and compare with param in controller or model as passing controller instances in model seems inappropriate to me Initially i am trying fetching and comparing in controller..

  @abc=Group.pluck(:group_token)

what I tried to do before is defined group_fetch method in model and used it in controller to check condition but I was not able to compare param which comes frome url dynamically

  def self.group_fetch
    Group.find_by group_token: 'UuzsG7NMvYFzxwPDdYgLxJbF'
  end

what will be the best way to fetch db column and compare it with the link param

You can use the exists? method which pretty much does what it says.

Group.exists?(group_token: params[:token])

You can use include? to check if the param is in the list. For example:

def your_method
  list = Model.pluck(:attribute)
  list.include?(params[:your_param])
end
