Hi all,
Learning RoR (and loving it!) to develop a website. A requirement of the website is enabling users to upload photos to be made viewable (dynamically) on the website. Is this something I can develop with RoR?
Thanks, Jeff
Piece of cake.. be sure to check out 'rails paperclip' via google. Tons of useful examples.

I've never done it, but lots of people have. All of them recommend the
Paperclip plugin. I think that's the one point of complete unanimity in
the Rails community. 
Thanks, Jeff

As a learner I have and still looking to find that same solution. paperclip is a full blown gem. To a student it would be profitable if anyone who knows how to do it in purely rails, would write a small example.
Say I have a form that includes submitting to other Models as well. How do I do that?
jobs/new.html.erb <% form_for [@job], :html => {:multipart => true } do |f| %> <%= f.error_messages %>
<dl> <dt><%= f.label "title" %></dt> <dd> <%= f.text_field :title %> <br> <span class="hint">"Senior Ruby Developer" or "HTML5 CSS3 Guru"</
</dd>
<dt><%= f.label "Location" %></dt> <dd> <%= f.text_field :location %> <br> <span class="hint">"Lincoln, UK", "Tallinn, Estonia", or "Anywhere"</span> </dd>
<dt>Category</dt>
<% Catergory.all.each do |category| %>
<dd> <label><%= f.radio_button :catergory_id, category.id %> <%= category.name.titleize %></label> </dd>
<% end -%>
<dt class="tarea"><%= f.label "Job descripton" %></dt> <dd class="tarea"><%= f.text_area :description, :size => "70x20" %></dd>
<dt class="tarea"><%= f.label "How you should apply" %></dt> <dd class="tarea">
<%= f.text_area :apply, :size => "70x6" %> <br> <span class="hint">Example: Send your portfolio to studio@safarista.com</span> </dd> </dl> <section class="company"> <h2>Now then, some`ing about your company. What should they know?</ h2>
<dl> <dt><%= f.label "Name" %></dt> <dd> <%= f.text_field :company %> <br> <span class="hint">Example: 'Safarista Design', 'Safrista Jobs' or '37signals'</span>
</dd>
<dt><%= f.label :logo %></dt> <dd> <%= f.file_field("upload") %> <br> <span class="hint"> Optional → Your company logo will appear at the top of youur listing. <br> 190px wide is optimal. If larger we will resize it automatically. </span> </dd>
<dt><%= f.label :url %></dt> <dd> <%= f.text_field :url %> <br> <span class="hint"> Ex: http://www.safarista.com </span> </dd>
<dt><%= f.label :email %></dt> <dd> <%= f.text_field :email %> <br> <span class="hint"> This is where we will send you a confirmation receipt of your payment and listing. </span> </dd> </dl>
</section><!--.company--> <%= f.submit 'Step 2: Proceed to preview your ad →' %>
<% end %>
My Models are:
Job belongs_to :catergory
# UPLOAD a file for the logo def upload uploaded_io = params[:job][:logo] File.open(Rails.root.join('public', 'images', uploaded_io.original_filename), 'w') do |file| file.write(uploaded_io.read) end end end
Catergory has_many :jobs
This is still not working, the image does not upload. Why? Please help in the simple inbuilt Rails. Am using v2.3.8
I would think it is much simpler...
Be sure you have ImageMagick installed (or an alternative) Be sure your migration defined the logo_file_name, logo_content_type, logo_file_size in the jobs table.
My example:
class Stage < ActiveRecord::Base # cycling race stage # belongs to a race-year, like 2010 - Vuelta d'Espana # has many stage standings (rider finish order) # has attached images for the route # map and the elevation profile belongs_to :raceyear has_many :stagestandings
has_attached_file :map, :styles => {:thumb => '100x100>'} has_attached_file :profile, :styles => {:thumb => '100x100>'} end
<%= form_for @stage, :html => {:multipart => true} do |f| %>
blah blah blah, fields to select raceyear, enter the stage name, description, terrain and distance, relevant image upload fields below <p> <%= f.label :map %> <%= f.file_field :map %> </p><p> <%= f.label :profile %> <%= f.file_field :profile %> </p> <%= f.submit %> <% end %>
Paperclip does all the heavy lifting.
http://railscasts.com/episodes/134-paperclip
to upload files without paperclip, you have to save the image details in the db and create an attribute accessor
def uploaded_picture=(picture_field) self.name = File.basename(picture_field.original_filename).gsub(/^\w._-/, ’ ') self.content_type = picture_field.content_type.chomp
self.data = picture_field.read end
but i should warn you that it makes no sense to reinvent the wheel , and there are many dangers for doing it the wrong way

You have an example: the Paperclip source code.
And if you're a beginner, then you definitely should not be trying to rewrite Paperclip.
BTW, you shouldn't be using <dl> for your forms; they're not semantically definition lists.
Best,
