Active Admin is one of the most famous Rails gems built to create instant administration pages. Active Admin is a highly recommended gem. I have known a lot of production-ready sites that are using this particular gem.
There are a few things you need to learn while working with Active Admin. Aside from your typical Rails application, you will also have to learn Active Admin DSL.
Here’s a problem often encountered by Ruby on Rails developers working with Active Admin.
This particular error informs us that strong parameters is being used and you will need to define the parameters your form is submitting. Here’s the particular fix:
ActiveAdmin.register Topic, as: "News" do
# Add the following
permit_params :event_date, :title, :body
You will need to replace
body with your parameters.
and voila! fixed!
