Instance Method Details

#setup_fixture_files ⇒ Object

Copies the fixture files from “Rails.root/test/fixtures/file_column” into the temporary storage directory used for testing (“Rails.root/test/tmp/file_column”). Call this method in your setup methods to get the file fixtures (images, for example) into the directory used by file_column in testing.

Note that the files and directories in the “fixtures/file_column” directory must have the same structure as you would expect in your “/public” directory after uploading with FileColumn.

For example, the directory structure could look like this:

test/fixtures/file_column/
`-- container
    |-- first_image
    |   |-- 1
    |   |   `-- image1.jpg
    |   `-- tmp
    `-- second_image
        |-- 1
        |   `-- image2.jpg
        `-- tmp

Your fixture file for this one “container” class fixture could look like this:

first:
  id:           1
  first_image:  image1.jpg
  second_image: image1.jpg

A usage example:

def setup
  setup_fixture_files

  # ...
end

def setup_fixture_files
  tmp_path = File.join(Rails.root, "test", "tmp", "file_column")
  file_fixtures = Dir.glob File.join(Rails.root, "test", "fixtures", "file_column", "*")
  
  FileUtils.mkdir_p tmp_path unless File.exists?(tmp_path)
  FileUtils.cp_r file_fixtures, tmp_path
end

#teardown_fixture_files ⇒ Object

Removes the directory “Rails.root/test/tmp/file_column/” so the files copied on test startup are removed. Call this in your unit test’s teardown method.

A usage example:

def teardown
  teardown_fixture_files

  # ...
end

# File 'lib/test_case.rb', line 91

def teardown_fixture_files
  FileUtils.rm_rf File.join(Rails.root, "test", "tmp", "file_column")
end

#upload(path, content_type = :guess, type = :tempfile) ⇒ Object

Returns a Tempfile object as it would have been generated on file upload. Use this method to create the parameters when emulating form posts with file fields.

Example:

def test_file_column_post
  entry = { :title => 'foo', :file => upload('/tmp/foo.txt')}
  post :upload, :entry => entry

  # ...
end

Parameters

  • path The path to the file to upload.

  • content_type The MIME type of the file. If it is :guess, the method will try to guess it.
