paperclip uploading muliple images, renaming the name"avatar"

I have installed paperclip for my ruby on rails project. But I cant upload multiple images. I have two different fields where I want to upload images for eg logo and picture.

Can I change the name "avatar" to indicate the name of the field?? Is it possible?

It sounds like you need some ideas to work with Rails & Paperclip:

Paperclip

Handles a file attachment & sends the data to your DB

- Creates DB entries:

your_definition_file_name
your_definition_content_type
your_definition_file_size
your_definition_uploaded_at

- Handles Objects called _your_definition

#app/models/attachment.rb
Class Attachment < ActiveRecord::Base
    has_attached_file :your_definition
end

Paperclip basically acts like a bridge between your db & your files -- meaning you just have to keep the object name consistent to get it to work

Code

If you have two fields (logo & picture), you'll need to declare them in your attachment model, pass their params, and add the columns in your table:

#app/controllers/attachments_controller.rb
def create
    @attachment = Attachment.new(attachment_params)
    @attachment.save
end

private

def attachment_params
    params.require(:attachment).permit(:logo, :picture)
end

#app/models/attachment.rb
Class Attachment < ActiveRecord::Base
    has_attached_file :logo
    has_attached_file :picture
end

#db/migrate
def change
     add_attachment :attachments, :logo
end

attachments
id | logo_file_name | logo_content_type | logo_file_size | logo_uploaded_at | picture_file_name | picture_content_type | picture_file_size | picture_uploaded_at | created_at | updated_at

Recommendation

The above code is not very DRY

I would recommend using a type attribute in your attachment model, setting the type each time you upload

This way, you can call the attachment as image or similar, uploading with the extra para of type each time:

#app/controllers/attachments_controller.rb
def create
    @attachment = Attachment.new(attachment_params)
    @attachment.save
end

private

def attachment_params
    params.require(:attachment).permit(:image, :type)
end

#app/models/attachment.rb
Class Attachment < ActiveRecord::Base
    has_attached_file :image
end

#db/migrate
def change
     add_attachment :attachments, :logo
end

attachments
id | image_file_name | image_content_type | image_file_size | image_uploaded_at | type | created_at | updated_at

Yes it is possible.

If you want to change "avatar" to "logo" using below command

rails g paperclip modalname logo

where logo is your field name.

I hope you understand and may be it solve your problem.
