Hello together, I developed a file upload in my application like this (files uploaded belong to a project): project_controller.rb: ---------------------- def upload_attachment project = Project.find(@params[:id]) begin project.attachments.create(params[:attachment]) rescue flash[:attachment_error] = "Error at Upload" end redirect_to :action => "edit_project", :id

I have a problem getting attachments to work in a specific case... I have the following data model (this is a relevant subset of it): - a log can have many journals - a journal belongs to a log and can have many attachments - an attachment belongs to a journal When adding on a new journal to an existing log the new journal form and the corresponding controller handle the attachment as well and

Hi, I am using send_data to allow users to download files from the database but ran into a small problem, it seems that files upload fine but when they download only 64kb of the file is sent. I''m using the basic rails code from the Agile book: #upload code in my sheet model def file=(document_field) self.filename = base_part_of(document_field.original_filename)

Hi, I want to get the size of an uploaded file that is saved in the database. Can you help me? In the edit view formular there is: <input id="attachment_title" name="attachment[title]" size="30" type="text" /> <input id="attachment_attachment" name="attachment[attachment]" size="30" type="file" />

Hi! Im developing a simple prototype of an application. It fills an oracle db with data about a file in the filesystem, and save the entire file in a blob along with some metadata. To get the file in the db i use a file_field form helper. All goes well with the radrails-integrated browser, but it doesnt work anymore in firefox. The problem is, firefox seems to cut the pathname from the file. Here

I''m trying to create a document upload system, where most of the code is the super class Document and just the path to file on the system is controlled by the sub classes.

I''m trying to use one form to upload a file to the file system and insert a title and description field into the database. I have no problem uploading files to the file system using the code from http://wiki.rubyonrails.com/rails/pages/HowtoUploadFiles There are more fields on the form than need to be inserted into the database, name and file. I need to pull out these extra fields

Okay, so this is driving me crazy. I''m trying to do a file upload using code from a book. What happens: I get wrong number of arguments (1 for 0) in the upload controller save action. No idea why. Schema: The schema for the picture model object is just a textfield named comments and a binary field called data. Upload controller: def get @picture =Picture.new end def save

I submitted this earlier, but the web forums went down and I''ve screwed up the thread, so I''m starting over. I''m trying to built a document upload system. The system has a main Document model with different subclasses for different types of documents. With the code below, if I attempt to create a Document, it works fine, but if I attempt to use one of the subclasses, I

I am checking the file size of an uploaded file and storing it in a filesize column. It will work just fine when the user uploads any files other than images (jpg,png,gif). Word, Excel, Powerpoint, .zip and more all work fine. This is my model asset.rb that handles the file upload. def newfile=(newfile_field) self.filename = base_part_of(newfile_field.original_filename) self.filetype

I have a model; I do photo = Photo.new(parameters) parameters contains: {"picture"=>#<File:C:/DOCUME~1/BART~1/LOCALS~1/Temp/CGI3180.1>} so i expect that the def picture=(filename) method is called in this constructor.. this is not the case. Does anyone know why? params[:photo].each_pair do |id, parameters| photo = Photo.new(parameters) end class Photo

I''m currently new to Rails and Ruby and I''m trying to learn from my mistakes, this time I''m trying to upload 2 files from a form for later processing, however, after I hit the "Submit" button.

I am creating a database for movies (films) and television shows (shows) that will have has_and_belongs_to_many relationships with the pictures table.

I''m trying to upload a file, display the upload progress and then update a table with the newly uploaded file. Is there a way to specify a :success handler for form_tag_with_upload_progress such that I have access to the request.response data (in the way I can with link_to_remote)? The :finish JavaScript is being executed but because there is no request object, the table

I have a simple form , with a file field = form_for (Clip.new), :html => {:multipart => true} , :remote => true , do |f| = f.hidden_field :user_id, {:value => current_user.id} = f.text_field :name = f.text_area :description = f.file_field :image = f.submit I18n.t(:add) generating the html code <form accept-charset="UTF-8"

Hi all, I was wondering about the class used when rails receives file uploads. Sometimes it appears to be a File, and other times it is a StringIO. Also it has methods such as original_filename that don''t appear to belong to either of these classes. I ask because I''m trying to work out how to test my fil upload related models and controllers. Is there some standardised way of

hello: I have code for upload image file to server file system.This works in rails 1.2.3.But in rails 2.1,it gets an error.

First off, I''m not trying to spec attachment_fu, I know it''s been tested. But, I added some code to that model that I do need to test. Basically, I need to somehow fulfill the "uploaded_data" property so I can actually run my tests(otherwise they fail because of validations). The "uploaded_data" field is what would grab the multipart data from form. Here
