I'm trying to save an image when adding a new Trip via an association.
tripphoto.rb has a belongs_to :trip
and my trip.rb has a has_many :tripphotos
. Furthermore the Carrierwave documentation requires a few more things like an uploader and such which I've set up correctly (It worked without the association!).
Along with it I've got mount_uploader :tripphoto, TripphotoUploader
in my trip.rb and accepts_nested_attributes_for :tripphotos, allow_destroy: true
to get my form working properly as such:
<%= fields_for :tripphotos do |photo| %>
Img <%= photo.file_field :filename %>
<% end %>
Nonetheless I get the error undefined method
tripphoto_changed?' for #`. A quick Google has no fitting result. Any advice?
P.S here's my Tripphoto table:
class Tripphoto < ActiveRecord::Base {
:id => :integer,
:filename => :string,
:trip_id => :integer,
:created_at => :datetime,
:updated_at => :datetime
}
Thanks in advance,
Edit: On request my Codes:
Trip.rb
class Trip < ActiveRecord::Base
attr_accessible :description, :title, :user_id,
:triplocations_attributes, :photo, :category_ids,
:start_city, :tripphotos, :img_url, :thumb_url, :images,
:tags_attributes
# validates :title, :length => {:minimum => 3}
# validates :description, :presence => true
# validates_associated :tags
has_many :triplocations, :dependent => :destroy
has_many :tripphotos, :dependent => :destroy
has_and_belongs_to_many :categories
has_and_belongs_to_many :tags
accepts_nested_attributes_for :triplocations, allow_destroy: true
accepts_nested_attributes_for :tripphotos, allow_destroy: true
accepts_nested_attributes_for :categories
accepts_nested_attributes_for :tags
mount_uploader :tripphoto, TripphotoUploader
end
Tripphoto.rb
class Tripphoto < ActiveRecord::Base
attr_accessible :filename, :trip_id
belongs_to :trip
end
The complete trip form
<%= form_for @trip, :html => {:multipart => true} do |a| %>
<%= a.label :title, "Routetitel" %>
<%= a.text_field :title %>
<%= a.label :description, "Omschrijving" %>
<%= a.text_area :description %>
<%= a.label :start_city, "Stad" %>
<%= a.text_field :start_city, :id => "cityName" %>
<% for category in Category.find(:all) %>
<div>
<%= check_box_tag "trip[category_ids][]", category.id, @trip.categories.include?(category) %>
<%= category.name %>
</div>
<% end %>
<%= a.fields_for :tags do |f| %>
<p>
<%= f.label :title, 'Steekwoorden:' %>
<%= f.text_field :title %>
</p>
<div id="inputFields"></div>
<% end %>
<div style="background: red;">
<%= fields_for :tripphotos do |photo| %>
Img <%= photo.file_field :filename %>
<% end %>
</div>
<%= a.submit 'Verstuur' %>
<% end %>
I had the same problem,
For me it was that I forgot to ran:
bundle exec rake db:migrate
That was the reason about the youruploaderattributte_changed? Missing Method in the moodel.
Two problems here :
filename
field in the Tripphoto
model in that case, and not the tripphoto
association.a.
in front of fields_for
