It seems that fileimg
field is nil
for the record f
. Make sure that it isn't `nil, and in that case, it shell be validated by a model validation rule.

I need to develop a simple File Upload
I'm using padrino and slim-templates. Also generated my views using the padrino command generator such as padrino g admin_pages modelName
. Now I want to add a fileUpload
field to the generated code... I'm getting this error:
undefined method `name' for nil:NilClass
My question is any way to automatically generate the admin page with this functionality or simply add the field manualy?
This is the code:
= f.text_field :newName, :class => 'form-control input-large input-with-feedback',
= f.label :content, :class => 'control-label'
= f.text_area :content, :class => 'form-control input-large input-with-feedback'
= f.file_field :fileimg
= f.submit pat(:save), :multipart => true ,:class => 'btn btn-primary'
Thanks in advance!
