User Avatars with ActiveStorage Discussion
Hi Chris, great episode. I posted a question about ActiveStorage but I have not received any response yet. Basically what i want to do is upload images for a has_many_attached directly from a controller. Let's say that given a folder route, upload all images in that folder, i know how to get the images and all, but i don't now how to attacht all those images?
Thanks in advanced.
I understand how you can create a variant to resize the original uploaded image, but how about other formatting, more specifically making the avatar a circle not a square. I realize that you can use CSS to achieve this, but such CSS doesn't always work. For example Outlook doesn't recognizes rounded corners CSS.
I built an app that generates email signatures and thus I want the image itself to have a circular formatting by applying a mask or something similar. How would I apply such a transformation to the image with active storage? What are the parameters for the variant?
object-fit: cover; don't end up with a perfectly centered image.
Would be interesting to see if it's possible to extend that to add remote URL for avatars — would replace things like Carrierwave pretty much entirely. Another nice to have for a future tutorial: previewing the avatar before saving.
i am having a problem , i want to work with active storage using uuids,
i changed the migration file but i am getting PG::UndefinedFunction: ERROR: function gen_random_uuid() does not exist can someone help .
i tried to add :
in the migration file but did not work
I got a problem with line
<%= image_tag gravatar_image_url(current_user.email, size: 100), height: 100, width: 100, class: "rounded-circle" %>
Showing app/views/devise/registrations/edit.html.erb where line #17 raised:
undefined method `escape' for URI:Module
With Ruby3.0, URI.escape was removed
Yes, I resolved it. When I trial this, I used Rails 7 alpha2. I need to
Install some libvips & make config for it to work --> I think we don't need this if you use Rails 7.0. Because I hear that lipvips are used by default in this latest Rails release
gem 'image_processing', '~> 1.2'
# config :vips lib for image processing
config.active_storage.variant_processor = :vips
Remove gravatar_image_tag from Gemfile and use this helper
def display_avatar_url(size: :middle)
height = AVATAR_SIZE[size] || size
avatar.variant(resize_to_fill: [height, nil])
I think use instazoom.mobi/tr is better, cause it can zoom and download any photos on Instagram.
