Edit Question
Title
Body
I have 2 models. Category and Post. They are connected using a has_many_and_belongs_to_many relationship. I checked in the rails console and the relationship works. I created checkboxes in activeadmin to set the post categories using this form field: f.input :categories, as: :check_boxes, collection: Category.all The problem is when I try to save it because every other field data (title, body, meta infos etc.) is saved, but the category stays the same even if I unchecked it, or checked another too. I am using strong parameters like this: post_params = params.require(:post).permit(:title,:body,:meta_keywords,:meta_description,:excerpt,:image,:categories) Please give me some suggestions to make active admin save the categories too! Best Wishes, Matt
