This is my working! model view and controller (without AJAX):
Model:
attachment.rb
class Attachment < ActiveRecord::Base
belongs_to :task
belongs_to :user
validates_presence_of :comment
def uploaded_file=(file_field)
self.name = base_part_of(file_field.original_filename)
self.content_type = file_field.content_type.chomp
self.data = file_field.read
end
def base_part_of(file_name)
File.basename(file_name).gsub(/[^\w._-]/, ‘’ )
end
end
View:
<% form_for(:attachment, :url => {:controller =>
‘attachment’, :action => ‘save’, :task_id => params[:id]}, :html =>
{ :multipart => true }) do |form| %>
Upload your file:
<%= form.file_field(:uploaded_file) %>
Comment:
<%= form.text_field(:comment) %>
<%= submit_tag(“Upload file” ) %>
<% end %>
Controller#save:
def save
params[:attachment][:user_id] = current_user.id
params[:attachment][:task_id] = params[:task_id]
@attach = Attachment.new(params[:attachment])
if @attach.save
flash[:notice] = “New attachment added”
else
flash[:notice] = “There were problems”
end
redirect_to(:controller => ‘tasks’ , :action => ‘edit’ , :id =>
params[:task_id])
end
And this is not working! controller and view with AJAX (model is the
same):
Controller#add_new:
def add_new
@task = Task.find_by_id(params[:id])
params[:attachment][:user_id] = current_user.id
params[:attachment][:task_id] = params[:task_id]
@attach = Attachment.new(params[:attachment])
if @attach.save
@attach = @task.attachments
end
render :partial => “./tasks/ajax_attachments”
end
View:
<% remote_form_for(:attachment,
:before => “Element.show(‘spinner’)”,
:success => “Element.hide(‘spinner’)”,
:url => { :controller => ‘attachment’,
:action => ‘add_new’,
:task_id => @task },
:update => ‘atte’,
:html => { :multipart => true }) do |form| %>
Upload your file:
<%= form.file_field(:uploaded_file) %>
Comment:
<%= form.text_field(:comment) %>
<%= submit_tag(“Upload file” ) %>
<% end %>
When I use ajax this code doesn’t work and error appears like that:
undefined method `original_filename’ for “E:\article.txt”:String
and ApplicationTrace
#{RAILS_ROOT}/app/models/attachment.rb:7:in uploaded_file=' #{RAILS_ROOT}/app/controllers/attachment_controller.rb:25:innew’
#{RAILS_ROOT}/app/controllers/attachment_controller.rb:25:in add_new' -e:4:inload’
-e:4
How can I fixed It???
