rails active storage get all attachment names
To get all attachment names using Active Storage in Ruby on Rails, you can follow these steps:
Step 1: Retrieve the associated record First, you need to retrieve the record that has the Active Storage attachments. For example, if you have a model called "User" with Active Storage attachments, you can retrieve a specific user by its ID:
user = User.find(id)
Step 2: Access the attachments
Once you have the user object, you can access its attachments using the user.attachments
method. This will return an instance of ActiveStorage::Attached::Many
that represents the attachments associated with the user:
attachments = user.attachments
Step 3: Get the attachment names
To get the names of all the attachments, you can use the blobs
method on the attachments
object. This will give you an array of ActiveStorage::Blob
objects representing the attached files:
blob_objects = attachments.blobs
Step 4: Extract the names
Finally, you can extract the names of the attachments from the blob_objects
array using the filename
method. This will give you an array of attachment names:
attachment_names = blob_objects.map(&:filename)
Now, the attachment_names
array will contain the names of all the attachments associated with the user.
Please note that you will need to replace "User" with the actual name of your model, and "attachments" with the name of your Active Storage attachment association.
