I am using cocoon from github to deal with accepts_nested_attributes_for. In my partial i am trying to manipulate nested attributes but it is not working. My code is in my partial :
.nested-fields = f.inputs do = f.object.myarrayfield.length
I have an error message :
undefined method `length' for nil:NilClass
If I do only that
.nested-fields = f.inputs do = f.object.myarrayfield
There is no error message and the page give me the value of the field :
The length method should give me 2 not nil, do you know why ?
