Я хочу загрузить несколько фотографий с помощью carrierwave. Вот что у меня есть:
image_uploader.rb
class ImageUploader < CarrierWave::Uploader::Base
# Include RMagick or MiniMagick support:
# include CarrierWave::RMagick
include CarrierWave::MiniMagick
# Choose what kind of storage to use for this uploader:
storage :file
# storage :fog
# Override the directory where uploaded files will be stored.
# This is a sensible default for uploaders that are meant to be mounted:
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
# Provide a default URL as a default if there hasn't been a file uploaded:
# def default_url(*args)
# # For Rails 3.1+ asset pipeline compatibility:
# # ActionController::Base.helpers.asset_path("fallback/" + [version_name, "default.png"].compact.join('_'))
#
# "/images/fallback/" + [version_name, "default.png"].compact.join('_')
# end
# Process files as they are uploaded:
# process scale: [200, 300]
#
# def scale(width, height)
# # do something
# end
# Create different versions of your uploaded files:
version :thumb do
process resize_to_fit: [50, 50]
end
version :small do
process resize_to_fit: [200, 200]
end
# Add a white list of extensions which are allowed to be uploaded.
# For images you might use something like this:
def extension_whitelist
%w(jpg jpeg gif png)
end
# Override the filename of the uploaded files:
# Avoid using model.id or version_name here, see uploader/store.rb for details.
# def filename
# "something.jpg" if original_filename
# end
end
project.rb
class Project < ApplicationRecord
mount_uploaders :images, ImageUploader
end
_form.html.erb
<%= form_with(model: @project) do |f| %>
<div id="new_project_form">
<%= f.label :name %><br />
<%= f.text_field :name %><br />
<%= f.file_field :images, multiple: true %><br />
<%= f.label :caption %><br />
<%= f.text_area :caption %><br />
<%= f.submit %>
</div>
<% end %>
show.html.erb
<h1><%= @project.name %></h1>
<%= image_tag @project.images_urls.to_s %>
<%= @project.caption %>
<%= link_to "edit", edit_project_path(@project) %>
Я получаю эту ошибку, когда загружаю проект с несколькими изображениями:
Звездочки :: Rails :: Helper :: AssetNotFound в проектах # show
Актив "[\" / uploads / project / images / 5 /% 5B% 22Screenshot_20181028-145315.png% 22% 5D \ "]" отсутствует в конвейере активов.
Что я сделал не так? Спасибо!
