I have spent 3 days trying to solve this:
I am trying to let users upload their profile picture on my site, using Paperclip.
Everything works fine, until user clicks the Upload button ( he is able to browse and choose a picture). When clicking upload button, Paperclip does not create files (original, small, medium & thumb version of the original picture), instead I got a routing error and no folder, no file is created, the :id field in the path looks empty, and the 'paperclip's attribute' are all set to NIL...
The Users controller:
def edit
@user = User.find(params[:id])
@title = "Upload a profile picture"
end
def update
@user = User.create(params[:user])
@title = "Update a profile picture"
end`
The views:
edit.html.erb:
<h1>
Ajouter une photo au profil
</h1>
<%= form_for @user,:user, :html => { :multipart => true} do |f| %>
<div class="field">
<%= f.label :avatar, "Upload ta photo" %>
<br />
<%= f.file_field :avatar %>
</div>
<div class="actions">
<%= f.submit "Upload" %>
</div>
<% end %>
clicks leads to update.html.erb:
<%= image_tag @user.avatar.url %>
<%= image_tag @user.avatar.url(:medium) %>
<%= image_tag @user.avatar.url(:thumb) %>
Last but not least the model User.rb:
class User < ActiveRecord::Base
attr_accessor :password
attr_accessible :name, :email, :number_of_positive_reco, :confidence_percent, :password,
:password_confirmation, :avatar, :avatar_file_name, :avatar_content_file, :avatar_file_size, :avatar_updated_at
has_attached_file :avatar , :styles => { :medium => "300x300>", :thumb => "100x100>"},
:url => "/public/images/:attachment/:id_:style.:extension",
:path => ":rails_root/public/images/:attachment/:id_:style.:extension"
# :default_url => "/images/Default_profile_picture.png"
email_regex = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
validates :name, :presence => true,
:length => { :maximum => 20}
validates :email, :presence => true,
:format => { :with => email_regex},
:uniqueness => {:case_sensitive => false}
validates :password, :presence => true,
:confirmation => true,
:length => { :within => 6..40 }
validates :number_of_positive_reco, :numericality => {:only_integer => true, :greater_than_or_equal_to => 0}
validates :confidence_percent, :numericality => { :greater_than_or_equal_to => 0.0, :less_than_or_equal_to => 1.0}
before_save :encrypt_password
# Return true if the user's password matches the submitted password.
def has_password?(submitted_password)
encrypted_password == encrypt(submitted_password)
end
def self.authenticate(email, submitted_password)
user = find_by_email(email)
return nil if user.nil?
return user if user.has_password?(submitted_password)
end
def self.authenticate_with_salt(id, cookie_salt)
user = find_by_id(id)
(user && user.salt == cookie_salt) ? user : nil
end
private
def encrypt_password
self.salt = make_salt if new_record?
self.encrypted_password = encrypt(password)
end
def encrypt(string)
secure_hash("#{salt}--#{string}")
end
def make_salt
secure_hash("#{Time.now.utc}--#{password}")
end
def secure_hash(string)
Digest::SHA2.hexdigest(string)
end
end
Here is the part of the log, where you SHOULD see paperclip written somewhere, no ?

So, everything is like: when clicking on upload, Paperclip is unable to store the files in the directory ...
In the console mode, I can set the picture without problem.
In the debug mode, I never see "paperclip" written, nowhere ... (I was expecting a [Paperclip] Saving attachment" somewhere...also, in the path of the routing error ":id" is set to "" ... instead of being the :id of the user, 4 for the 4th user...but even with a default path like "/images/" the problem remains...
Does this make you think about something I may have forgotten ?
(ImageMagick works fine, I have added the multipart true in the form, and normal user has the rights to create a folder)
Many thanks in advance for any hints!
