How to destroy model with values

I'm kind of new to rails. I have a model called follows that has to values (requestor and following). I am having trouble creating a button that destroys a select model with two values

<dt>User ID:</dt>
<dd><%= @user.id %></dd>

<dt>User email:</dt>
<dd><%= @user.email %></dd>

<% if Follow.where(:requestor => current_user.id, :following =>@user.id).present? %>    
    <%= button_to 'Unfollow', follow_url, method: :delete, class: "text-danger", data: { confirm: 'Are you sure?' } %>
<% else %>
    <%= button_to "Follow", {:controller => 'follows', :action => 'create', :requestor => current_user.id, :following => @user.id}, {:method => :post} %>
<% end %>

The Follow button below in the else statement works, but I cannot figure out how to get the destroy button to work. I'm executing these buttons on the User show page instead of on the follow index.

def destroy
    @follow.destroy
    respond_to do |format|
      format.html { redirect_to follows_url, notice: 'Follow was successfully destroyed.' }
      format.json { head :no_content }
    end
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_follow
      @follow = Follow.find(params[:id])
    end

    # Only allow a list of trusted parameters through.
    def follow_params
      params.permit(:requestor, :following)
    end
    def require_permission
      if Follow.find(params[:id]).user != current_user
        redirect_to goals_url, flash: { error: "You do not have permission to do that."}
      end
    end
end

I keep getting couldn't find Follow with 'id' error. It deletes sometimes, but the majority of the time I get this error.
