How to open a file in my Fabricator #275

Closed oasisweng closed 8 years ago

oasisweng commented 8 years ago 
Fabricator(:image) do
  image { File.open(File.join(Rails.root, 'test', 'fabricators', 'assets', 'ex1.png'))}
end

I want to fabricate an image instance with a test image file. But it gives me the following error Errno::EMFILE: Too many open files @ rb_sysopen.

Full error stack:

Errno::EMFILE: Too many open files @ rb_sysopen - /Users/oasisweng/Documents/Repos/2buyi/test/fabricators/assets/avatar.png

What is the correct practice to open a file in Fabrication?

I am using Rails 4 and I upload the images through Carrierwave.
