I'm using attribute_fu and paperclip to add multiple images to a specific record.
This is working great when creating a new record but when I want to add new images to an existing record through a common scaffold update, the images upload but replace the existing images.
Any thoughts or advice?
I'd found maybe the problem.
my model upload has article_id, description, photo_file_nane
In my partial: _upload.rhtml
if I just put:
<div class="upload">
<%= f.file_field :photo %>
<%= f.remove_link "remove" %>
</div>
when I update, it delete my photos.
but if I put:
<div class="upload">
<%= f.text_field :description %>
<%= f.file_field :photo %>
<%= f.remove_link "remove" %>
</div>
It works fine

I recently noticed that on my form, if I try to upload an empty file the page will get redirected to edit instead of create. If I try to upload the file with some text in it, the form will direct to create. I couldn't find any indication that this would happen as I create my object every time (it's never persisted). Is there an explanation behind this?
The code looks something like this:
//controller
def upload
#new_cool_file = CoolFile.new
end
//form in upload.html.erb
<%= form_for #new_cool_file, html: {role: "form"} do |f| %>
<div class="form-group">
<%= f.label :file %>
<%= f.file_field :file %>
</div>
<%= f.submit "Submit"%>
<% end %>
I think you do some wrong in the rails routes.rb file , can you please see tutorial about file upload.

In rails is there any simple way to implement select or create from view.
Eg:
Product has_many(or has_one) Tags.
While creating new Product I can select existing tags or create new one.
This can be done by using JavaScript and other ways are there.. But all will take more time and effort.
Please share if you know other simple way...
Edit:
Something like this.
But imagine you have 100 tags or more ! your page will look bad with 100 checkbox or more..., one elegant way to do this is by using a jQuery plugin called jQuery Tokeninput i use it in my project and it's very helpful for what do you want, you can find the plugin Here
This is a screencast on how to use it : Token fields
and this is the revised version : Token Fields (revised)
check also this blog post about the same plugin if you want too How to create a token input field where the user can also add new items
cheer
Yep.
You are after nested forms. Try, https://github.com/ryanb/nested_form
For example,
<% form_for #product do |f| %>
<%= f.error_messages %>
<p>
<%= f.label :name %><br />
<%= f.text_field :name %>
</p>
<% f.fields_for :tags do |tag| %>
<p>
<%= tag.label :content, "Tag Name" %><br />
<%= tag.check_box :content %>
</p>
<%= tag.link_to_remove "Remove this tag" %>
<% end %>
<%= tag.link_to_add "Add new tag" %>
<p><%= f.submit "Submit" %></p>
<% end %>
Setup the controller and model as given in the documentation and try the above code in the view. This railscast will help you a lot in figuring nested forms http://railscasts.com/episodes/197-nested-model-form-part-2
I'm using CarrierWave and Nested Form Gem. Using the section titled 'Making uploads work across form redisplays' on the Carrierwave github page(https://github.com/jnicklas/carrierwave) I'm able to successfully store the cache so that even if the user makes a mistake then the file is saved. The first time I hit the page and click "Upload File" it works and shows the name of the file as well as a small thumbnail icon indicating the type of file that has been uploaded.
However the file input button is blank upon a redisplay and the icon is gone. However I know it's there because if I submit again with valid information and leave the file input button alone it creates a new resource. Here's a snippet of my code.
<%= nested_form_for #resource, :html=>{:multipart => true } do |f| %>
<p>
<%= f.label :title %><br />
<%= f.text_field :title %>
</p>
<%= f.fields_for :attachments do |attachment_form| %>
<p>
<%= attachment_form.label :file %>
<% if !attachment_form.object.file.path.blank? %>
<% file_info = get_cache_file_info attachment_form.object.file.path %>
<%= image_tag(File.join('/tmp/cache/', file_info[:folder])) #THIS DISPLAY CORRECTLY %>
<% end %>
<%= attachment_form.file_field :file %>
<%= attachment_form.hidden_field :file_cache %>
</p>
<%= attachment_form.link_to_remove "Remove this attachment" %>
<% end %>
<%= f.link_to_add "Add attachment", :attachments %>
<p><%= f.submit %></p>
<% end %>
I'm wondering if I have to edit the HTML file input to display the icon or is there some other Rails Way to take care of this. Also the image_tag display correctly, but for my application having users upload text files so the images aren't very helpful.
Thanks in advance!
Update
I also tried setting the value of the 'input' tag like so:
<%= attachment_form.file_field :file, :value => "#{File.join(file_info[:folder], '/',attachment_form.object.file.identifier)}" %>
and that didn't work either. The value of the 'input' tag is set correctly, but it still shows up as "No file selected"
The CarrierWave introduction doesn't make this very clear, but it sounds like your code is functioning 'correctly'. The cache field just serves to ensure that your attachment will be saved after a valid submission.
This document explains that the file input element's FileList should be read only, presumably for security reasons.
I have CarrierWave (0.6.1) and Nested Form gem installed. I have a Resource model with many Attachments which have a FileUploader.
I have a nested form where users can upload multiple files with one resource. I am following the section on github (https://github.com/jnicklas/carrierwave) that says how to make uploads work across redisplays unfortunately it's only for 1:1 ratio.
Here's the code that I have:
<%= nested_form_for #resource, :html=>{:multipart => true } do |f| %>
<p>
<%= f.label :title %>
<%= f.text_field :title %>
</p>
<%= f.fields_for :attachments, #attachment do |attachment_form| %>
<p>
<%= attachment_form.label :file %>
<%= attachment_form.file_field :file %>
<%= attachment_form.hidden_field :file_cache %>
<%= image_tag(attachment_form.file_url) if attachment_form.file? # DOESN'T WORK!!! %>
</p>
<%= attachment_form.link_to_remove "Remove this attachment" %>
<% end %>
<%= f.link_to_add "Add attachment", :attachments %>
<p><%= f.submit %></p>
<% end %>
Everything works and it populates the file_cache variable just fine for the attachment_form however I somehow need to add the following line in there to show the user the image of the document:
<%= image_tag(attachment_form.file_url) if attachment_form.file? %>
However there's a number of problems with this. First of all attachment_form is referencing the form_builder whereas I want the actual attachment. Second, attachment knows nothing about file.
Probably need to use another type of looping mechanism, but I'm new to Ruby so any help is appreciated.
Thanks all!
If you try this:
<%= image_tag(attachment_form.object.file_url) if attachment_form.object.file? %>
You will be able to show previous uploaded images. But if you want to display uploaded right now, you need to use something else. For example: https://github.com/blueimp/jQuery-File-Upload/wiki/jQuery-File-Upload-v4-for-Rails-3
Sorry, if I misunderstood your question.
I'm using the Refinery content management system with a the Portfolio plugin
see http://github.com/resolve/refinerycms
I wanted to create a title and description for images uploaded to
Refinery using Refinerycms-Portfolio
so far I have done the following;
added the columns to the images table;
$script/generate migration AddTitleToImages title:string
$script/generate migration AddBodyToImages body:text
$rake db:migrate
modified the field div in this file, * highlighted
vendor/plugins/images/app/views/admin/images/_form.html.erb
<div class='field'>
<%= f.label :uploaded_data, 'Image' %>
<% if params[:action] =~ /(edit)|(update)/ %>
Use current image
<em>or</em>, replace it with this one...
<% end %>
<%= f.file_field :uploaded_data %>
***** <%= f.label :title, 'Title' %>
***** <%= f.text_field :title %>
***** <%= f.label :body, 'Description' %>
***** <%= f.text_area :body, :class => "wymeditor", :rows => 7 %>
</div>
Added these lines to the main image partial in
vendor/plugins/refinerycms-portolio/app/views/portfolio/
_main_image.html.erb
<h2><%= #image.title %></h2>
<p><%= #image.body %><p>
This works in the back-end except for a few visual bugs.
The problem with this is when i click through the thumbnails in the
front-end the titles and descriptions keep stacking on top of the
previous titles and descriptions. The main image changes fine, but
instead of refreshing the title and description, it adds the new one
above the previous titles and descriptions.
How can i stop this repetition so that only one title and description
will show at a time?
I'm new to Rails and I am using Rails-2.3.5 and I suspect this can be solved using Java Script
any help will be greatly appreciated,
John
You will need to edit the portfolio.js file in the /public/javascripts directory to show/hide the correct titles and descriptions on the portfolio page. This file handles all the AJAX features for the front end of the portfolio plugin.
Best of luck!
