Trying to perform a method on a params in Rails

I want to write a method that loops through all the params to make sure they aren't all blank.

My params are:

params[:search][:company]
params[:search][:phone]
params[:search][:city]
params[:search][:state]
params[:search][:email]

I have this method:

def all_blank_check(params)
  array=[]

  params[:search].each do |key, value|
    array << value unless value.blank?
  end

  if array.count < 1
      return true
  else
     return false
  end
end

But when I try something like all_blank_check(params) I get the following error:

NoMethodError (undefined method `all_blank_check' for #<Class:0x108c08830>):

Do I need to convert the params to an array first? Can't I perform a method on params?

Edit - full source:

        def index
          @customers = Customer.search_search(params)
        end


    def self.search_search(params)
      search_field = []
      search_values = []
      array = []
      test = ''    

      if !params[:search].nil? && all_blank_check(params[:search]


              if !params[:search].nil? && !params[:search][:company].blank?
              search_field << 'customers.company LIKE ?'
              search_values << "%#{params[:search][:company]}%"

              end

              if !params[:search].nil? && !params[:search][:city].blank?
              search_field << 'customers.city = ?'
              search_values << "#{params[:search][:city]}"
              end

              if !params[:search].nil? && !params[:search][:phone].blank?
              sea开发者_Go百科rch_field << 'customers.phone_1 = ?'
              search_values << "%#{params[:search][:phone]}%"
              end

            conditions = [search_field.join(' AND ')] + search_values

            Customer.where(conditions).includes(:customer_contacts).limit(10)
        end
    end


    def all_blank_check(params)
        params[:search].each do |key, value|
          array << value unless value.blank?
        end

        if array.count < 1
            return false
          end
          if array.count > 1
            return true
        end
    end

You can also use more Ruby-minded code like this:

def self.all_blank?(params)
   params[:search].count{|key, value| !value.blank?} == 0
end

This counts the values that are not blank; if the number is 0, it means all are blank. It avoids creating a new array just for counting.

The problem is not the type of params, the problem is that the method all_blank_check does not exist on the object you call it on.

You defined it as an instance method and you're trying to call it from the class method search_param, which won't work.

If you want to make all_blank_check a class method you need to change the definition to def self.all_blank_check(params) - same as search_param.
