file_validators's Issues

JSON parser error when a string value is passed

I am trying to use file_validators to validate the content type of avatars in my rails api. The client selects a file, submits the form, gets the content type validated with

validates :avatar, file_content_type: { allow: /^image\/.*/ }

However, the client currently has a bug where it sends a text string instead of an uploaded file. I would expect this to NOT be of an image content type and therefore fail the validation. But it seems file_validators in

file_validators/lib/file_validators/validators/file_content_type_validator.rb

Line 43 in e9c12fa

value = JSON.parse(value) if value.is_a?(String)

tries to parse the string to json. That raises an exception because the string is not valid json

JSON::ParserError: expected false at line 1, column 2 [parse.c:152]

Maybe the correct behaviour would be for the gem to rescue a json parser error? Nevertheless Thanks for a great gem! :)

how to show properly using Rspec the Quote Mark's

I'm using Rspec and the gem file_validators for testing and I need to put properly the output of the Quote Mark's("txt") like theses:
expect(page).to have_content expect(page).to have_content "You are not allowed to upload \"txt\" files, allowed types: jpg, jpeg, gif, png"
or
double_quotes = ""txt"".html_safe
expect(page).to have_content expect(page).to have_content "You are not allowed to upload '#{double_quotes}' files, allowed types: jpg, jpeg, gif, png"
But I'm having a failure error for show this:
Failure/Error: expect(page).to have_content expect(page).to have_content "You are not allowed to upload '#{double_quotes}' files, allowed types: jpg, jpeg, gif, png" expected to find text "You are not allowed to upload '"txt"' files, allowed types: jpg, jpeg, gif, png" in "News CityToggle navigationHomeAdminSigned in as [email protected] out×Post has not been created.New Post* TitleSubtitleFileYou are not allowed to upload \"txt\" files, allowed types: jpg, jpeg, gif, png* Content It will serve for show images about the posts."

Reform + Paperclip + S3

Let's consider following example:

  # .../pitches_controller.rb

  def upload_avatar
    pitch = Pitch.find(params[:id])
    form = PitchAvatarForm.new(pitch)
    if form.validate(pitch_avatar_params)
      form.save
      on_pitch_avatar_upload_succeeded(form)
    else
      on_pitch_avatar_upload_fialed(form)
    end
  end

# .../forms/pitch_avatar_form.rb

class PitchAvatarForm < Reform::Form
  model :pitch

  property :image
  property :image_file_name
  property :image_content_type
  property :image_file_size

  validates :image,
            file_content_type: { allow: ['image/jpeg', 'image/jpg', 'image/png'] },
            file_size:  { less_than: 2.megabytes }
end

On each form#save execution it couses following error:

form.save
NoMethodError: undefined method `sub' for nil:NilClass
from /Users/rapide/.rvm/gems/ruby-2.3.0@bttf/gems/paperclip-4.2.2/lib/paperclip/storage/s3.rb:255:in `s3_object'

I fixed this issue by assigning attributes to the pitch before creating the form but it looks like an ugly hack. Any idea how to solve this in better way?

.docx format validation not working

having validation:

validates :cv,
  file_content_type: {
      allow: %w(
        application/msword
        application/vnd.openxmlformats-officedocument.wordprocessingml.document
        application/x-pdf
        application/pdf
      ),

it works fine for .pdf and .doc but not for .docx
Even when manually setting type:

ActionDispatch::Http::UploadedFile.new({
  filename: @data[:filename],
  type: 'application/vnd.openxmlformats-officedocument.wordprocessingml.document',
  tempfile: tmp_file_data
})

looks like application/vnd.openxmlformats-officedocument.wordprocessingml.document is not supported.

Not working for multiple file uploads

Carrierwave has the ability to upload multiple files. I just tried if file_validators still work with that, but it doesn't seem to, using the following code:

mount_uploaders :documents, DocumentUploader
validates :documents, file_size: { less_than_or_equal_to: 100.kilobytes }

and I was able to upload an image over 1MB. Is there support being planned for this?

Active Storage uploads failed

Using Active Storage failed using file size validators

Cocaine is deprecated

DEPRECATION: The cocaine gem is deprecated. Please upgrade to terrapin. See https://github.com/thoughtbot/terrapin/ for further instructions.

use mimemagic to determine content type by content

Hello, there is note in mimemagic gem README.

MimeMagic is a library to detect the mime type of a file by extension or by content.

MimeMagic.by_magic(File.open('test.html'))

So in what cases should I use cocaine ? When mimemagic is not enough?

Validate array of files

Hello,
I'm currently using postgres array column + carrierwave for uploading files. Is it possible to add file validation for array column?
Thanks

Active Storage attachment is nil

Using File Validators file_content_type and file_size with Active Storage throw a Module::DelegationError error (content_type delegated to attachment, but attachment is nil and size delegated to attachment, but attachment is nil), when a form for a Model thats being validated gets submitted without attaching a file.

The following workaround works for now:

validates :image, file_content_type: { allow: ['image/jpeg', 'image/png', 'image/gif'] }, if: -> { image.attached? }

This might fit into the README, should I open a PR?

mode: :strict error

when i want use mode: :strict i see this exception, how i can fix it?

Thanks

ArgumentError: Unknown validator: 'FileContentTypeValidator'

Hello!

I'm currently migrating an application from PaperClip to ActiveStorage. As part of thoughtbots migration guide, they suggested using your gem. Our model, lets call it 'Organization' like they do in the example, has a 'logo' attached to it. Using their migration guide, I added the following to the Organization model:

  validates :logo, file_content_type: {
    allow: ['image/jpg', 'image/jpeg', 'image/png', 'image/gif'],
    if: -> { logo.attached? },
  }

I expected this to work out of the box, which it does when I'm uploading a file. If I remove say jpeg from the list and try to upload a jpeg, I get an error. The problem is that when I try to run basically anything else in console, like Organization.find(ID) or try to delete a record for example, I get the error mentioned in the title:

ArgumentError: Unknown validator: 'FileContentTypeValidator'
/gems/activemodel-5.2.1/lib/active_model/validations/validates.rb:121:in `rescue in block in validates'

Our app is running on Rails 5.2
Please let me know if you can help or if we should take an alternative approach, thanks!

Dependency on cocaine gem still in 2.3.0

Although a merge request has been merged and the readme already mentions terrapin gem as a dependency when using mode: :strict I still get a warning pointing at dependency on cocaine gem which is deprecated:
file_validators requires 'cocaine' gem as you are using file content type validations in strict mode
from here
I checked the latest version on rubygems.org and it seems to be at version 3.0.1 beta.
bundle update file_validators returns Bundler attempted to update file_validators but its version stayed the same

Gemfile.lock
file_validators (2.3.0)

Is it possible to upgrade it?

Fails with ActiveRecord and CarrierWave uploader

Greetings, and thank you so much for all the work you guys put into the gem!

Now to the business... I have the following kind of model:

class VaultDoc < BaseModel
  mount_uploader :document, VaultDocUploader

  validates :document,
            file_size: { less_than_or_equal_to: 25.megabytes },
            file_content_type: { allow: ->(record) { record.allow_content_types }, mode: :strict },
            on: :create
end

With the following kind of VaultDocUploader:

class VaultDocUploader < CarrierWave::Uploader::Base
  include CarrierWave::RMagick
  
  storage :file

  version :thumb, if: :thumbable? do
    process resize_to_fit: [315, 445], if: :image?
    process pdf_preview: [315, 445], if: :pdf?
  end

  def thumbable?(file)
    image?(file) || pdf?(file)
  end

  def image?(file)
    file.content_type.include? 'image'
  end

  def pdf?(file)
    file.content_type == 'application/pdf'
  end
end

(There's a lot more to it, but seems to be irrelevant)

Validation raises an exception when I'm trying to create an instance of VaultDoc during tests:

NoMethodError: undefined method `eof?' for #<VaultDocUploader:0x00007feaa4a46168 @model=#<VaultDoc id: nil ...>, @mounted_as=:document, @staged=true, @file=#<CarrierWave::SanitizedFile:0x000000000d962d20 @file="/app/tmp/vault-cache/1691776062-272660352770104-0001-2145/logo.png", @original_filename="logo.png", @content_type="image/png", @content=nil>, @filename="logo.png", @cache_id="1691776062-272660352770104-0001-2145", @identifier=nil, @versions={:thumb=>#<VaultDocUploader::Uploader22380:0x000000000d960750 @model=#<VaultDoc id: nil, document: nil, state: "uploaded", title: "My Document", original_filename: nil, thumb_present: true, created_at: nil, deleted_at: nil, vault_keeper_id: "93419cd4-87ca-42ec-8ae4-ecfda99b7620">, @mounted_as=:document, @staged=true, @file=#<CarrierWave::SanitizedFile:0x000000000d96a8e0 @file="/app/tmp/vault-cache/1691776062-272660352770104-0001-2145/thumb_logo.png", @original_filename="logo.png", @content_type="image/png", @content=nil>, @filename="logo.png", @cache_id="1691776062-272660352770104-0001-2145", @identifier=nil, @versions={}, @format=nil, @parent_version=#<VaultDocUploader:0x00007feaa4a46168 ...>, @parent_cache_id="1691776062-272660352770104-0001-2145", @original_filename="logo.png", @geometry={:width=>315, :height=>315}, @cache_storage=#<CarrierWave::Storage::File:0x000000000a47d088 @uploader=#<VaultDocUploader::Uploader22380:0x000000000d960750 ...>, @cache_called=nil>>}, @format=nil, @original_filename="logo.png", @cache_storage=#<CarrierWave::Storage::File:0x000000000d961628 @uploader=#<VaultDocUploader:0x00007feaa4a46168 ...>, @cache_called=nil>> # /gems/file_validators-3.0.0/lib/file_validators/mime_type_analyzer.rb:27:in `extract_with_file' # /gems/file_validators-3.0.0/lib/file_validators/mime_type_analyzer.rb:16:in `call' # /gems/file_validators-3.0.0/lib/file_validators/validators/file_content_type_validator.rb:60:in `get_content_type'

This used to work on v2.3.0 and worked up to v3.0.0.beta1 (inclusive), whereas v3.0.0.beta2 and v3.0.0 (release) don't work.

Here are my thoughts on what's happened: https://github.com/musaffa/file_validators/pull/32/files#r1291636492

Media type spoofing

Hello,

I think that media type spoofing is a bit problematic. For example I have a my_file.torrent which has a content type application/x-bittorrent and the file, even though is valid, it is being detected as spoofed.

I believe that the validation shouldn't make such an automatic detection but it should be up to the caller, via a new validator called 'file_extension_validation' to make such decisions.

Thank you for your time

Translate the file content types to human readable format

Given that I have the following model:

class Profile
  include ActiveModel::Validations

  attr_accessor :avatar
  validates :avatar, file_content_type: { allow: ['application/json'] }
end

I will get the following error message when the file is not valid:

file_validators/lib/file_validators/locale/en.yml

Line 10 in 55b8c7f

allowed_file_content_types: ! 'file should be one of %{types}'

With the allowed content type interpolated as specified in the validate statement, i.e. application/json as defined here:

file_validators/lib/file_validators/validators/file_content_type_validator.rb

Line 88 in 55b8c7f

error_options = options.merge(types: option_types.join(', '))

I suggest that we would convert the Mime type into human readable format, e.g. in this case JSON.

This could be done e.g. as follows:

"application/json".match(%r{/([a-z]+)})[1].upcase

Not validate content_type properly when use carrierwave-aws

Hi,

we use in our application carrierwave-aws gem for storing files to S3. And we also use the file_validators gem for validating content_type of uploaded file.

What happen is that when we assign file (for example pdf file and we check that content_type is 'application/pdf'). The record is valid and we can store it. But when we load the record from database and it load file from S3, then record is invalid. The file behave like 'application/octstream' instead of 'application/pdf' . But if I ask for record.content_type => 'application/pdf'

So I think the problem is on this line https://github.com/musaffa/file_validators/blob/master/lib/file_validators/validators/file_content_type_validator.rb#L59

If there happen any error with content_type detection it as default return 'application/octstream' .

If you can give me an idea, how to fix it, I will do it.

Thanks a lot.

Systematic crashes with carrierwave-aws when no file uploaded

I cannot seem to use the file_validators gem with carrierwave-aws. It systematically cause model crashes when saving without uploaded file. Apparently the file validations always trigger, even when there is no file, and that cause Aws::S3::Errors::NotFound:. I had to remove the gem from the Gemfile.

Here is a backtrace :

Reform + Paperclip + File Validators

Hi!

I'm trying to validate a paperclip :image in a Form object but it throws the following error on create:
Paperclip::Errors::MissingRequiredValidatorError.

I've already include ActiveModel::Validations in my Form Object as well as Paperclip validators but. Is your gem working with Paperclip?
Thanks in advance!

3.0.0 stable release?

Hi @musaffa,

What's missing for a 3.0.0 stable release? I can see a few outdated issues in here, just waiting to be closed, and some staled PR but what did you expect to put into the stable 3.0.0 before you release it?

Maybe I can help you to reach that goal.

Interpolation for detection content type

Is it possible to interpolate the detected mime-type into the error message?

rails console - "ArgumentError (Unknown validator: 'FileSizeValidator')"

rails server (app works as expected) however in rails console i got

"ArgumentError (Unknown validator: 'FileSizeValidator')"

using :strict and not having `file` available should complain loudly

Many docker images have a minimal set of tools, in the case of the jruby docker image file is not available by default. In this case there is a very quiet note from file_validators and the content_type check returns an octet-stream. If you're using :strict and the command fails because the command cannot be found, that failure should occur very obviously. Currently a "file: not found" log line occurs, I suggest that it should be an exception.

Code in question:

file_validators/lib/file_validators/utils/content_type_detector.rb

How to use validators in our own specs?

Hi,

Great work on the gem!

I'm trying to use the gem's validators in my own rspec suite, so that I'm able to say something like:

  it { is_expected.to allow_file_size(1.5.megabyes, :image) }

...or similar.
Is there any way to include the validators in the rspec?

No such file or directory - file

Hey , I'm trying to package file_validators for debian . Currently I'm getting an error when running the tests. Can you help me here as to why this is happening and what should be done to fix this?
