Good Day, i am trying to update the rating of a user using form_for to populate the text_field of its current rating and then update it to user entered value. So far, its seems all simple but something doesn't seem well and i am getting this error. Help will be highly appreciated!

user controller:

def edit_rating
      @ad = Ad.find(params[:id])
      @user = User.find(@ad.user_id)

      if @user.update_attributes(user_params)
        flash[:notice] = "User Updated Successfully"
        redirect_to(:action => 'index')
      else
      end
    end

    def user_params
      params.require(:user).permit(:firstName, :lastName, :email , :password , :location, :rating)
    end

edit_rating view:

<h2>
    Edit User Rating
</h2>

<h4>
    Name: <%= @user.firstName %>
</h4>

<p>
    Current Rating: <%= @user.rating%>
</p>

<%=form_for(:user , :url => {:action => 'edit_rating' , :id => @user.id}) do |f| %>

    <p>
        Updated Rating: <%= f.text_field(:rating) %>
    </p>

    <%= submit_tag("Update Rating") %>
<% end%>

This is the error that i am getting.

You can do the reverse not to permit you can only use the params you only want to use:

@user.update_attributes(rating: params[:user][:rating])
