I am new to Rails and I encountered a unique behaviour(seems magick to me for now).
I added an attribute accessor in a models file
attr_accessor :git_url
I am sure I did not add any validation for this accessor.
I am using simple form gem for forms. When I include this accessor in the form and submit the form by entering invalid url, a hint appears (Please enter a URL) and form does not submit
<%= f.input :git_url %>
Its cool but I wanna know from where is this validation coming
Help would be greatly appreciated!
