image url not working

[selvamani-subramani]

when I get the image url through User.first.avatar.url, It generate the url but when I try the url in browser or html, its not showing the image. My model code

has_attached_file :avatar,
    :storage => :dropbox,
    :dropbox_credentials => {app_key: "123445", app_secret: "1234456", access_token: "123456", access_token_secret: "123456", user_id: "191409863"}

  validates_attachment_content_type :avatar, :content_type => ["image/jpg", "image/jpeg", "image/png", "image/gif"]

It is uploading the file to my dropbox successfully. So when I try User.first.avatar.url, its generates url like this https://dl.dropboxusercontent.com/u/191409863/mclarenp1_QY5vmfTw.jpg when I access this, the page shows dropbox error page instead on image.

I have the same issue. From what I have read here, this might be that dropbox stopped allowing free users to get a public folder. So either you need to update to pro or you do it privately.

edit :
To solve this issue, you need to set in your model file

:dropbox_visibility => 'private'

And after it should work without any problem.
