similar to: fiile_column persistent across different forms

Looks like my first question a couple of days ago wasn?t very clever asked, at least very sucessfull.... So, anyway...i will try it again: I have to prefix that I am far away from fully understanding the overall concept yet, and there?s no way to get some hints in the www so far, at least my resaerches dont lead to any helpfull stuff. image_controller.rb: def create MiddleMan.new_worker

Does anyone know if it''s possible to set constraints to the size & type of file that file_column will accept? I''d like to limit to image files of less than 2MB. If this isn''t possible with file_column, is there a graceful way of getting the controller to handle it? thanks dorian -- -- I do things for love or money

i have a model with this: file_column :image validates_file_format_of :image, :in => ["gif", "png", "jpg"] If inthe form the user not insert the image i receive an error. If i remove: validates_file_format_of :image, :in => ["gif", "png", "jpg"] it works. Is possible do the validation only when user insert the image in form? i

1) installation is not as smooth as some other plug-ins. If you follow the instructions on http://www.kanthak.net/opensource/file_column/ it makes a directory called trunk instead of file_column. You have to manually rename it to file_column. I guess this is a minor annoyance but it gives me the feeling that things aren''t quite like other plugins. 2) I get this error: undefined

I''m trying to use file_column as a Rails plugin. Of course I read the doc (from Sebastian, this maillist) and little bit of source (as good as I, newbie, could understand it).. But I''m not able to implement it in my app.. I''m a totally newbie with less software development experience. I get the file_column_field in my view with simply invoking the helper... (:multipart

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

file_column is great -- but I need a way to run through the validations (ie: validates_file_format_of) before saving. That is, when a user first uploads an image it is displayed in the view but not ''saved'' until they click the ''Save'' button on the form. I want to display an error message/disable the ''Save'' button if the file they just

I am using the very helpful file_column extension in my app. The uploading portion works great - no problems. Where I am having an issue is displaying the images in my view. My code looks like this: <% for @record in @main_box_releases -%> <%= image_tag(url_for_file_column("record", "record_cover")) %> <% end -% @record is an instance of a class called

this seems so stupid, I keep thinking I''ve dealt with this before but I have this code <h1>Portraits</h1> <% if @image.portrait == 1 %> <%= image_tag(url_for_file_column ''image'', ''file'', ''thumb'') %> <% else %> <h1>Landscapes</h1> <%= image_tag(url_for_file_column

Hi, Say I have a model Event that has a file_column called ''pdf''. I want to send out emails that contain the URL for the pdf file that''s associated with the Event. I also want to test the emails, so I''d need to be able to get at the URL for the pdf inside my unit tests. I don''t see how I can use url_for_file_column in this situation. Doing <%=

Hmm, I''m using file_column and going by this tutorial, the files upload ok and I can see the fields updated in the database, but I am getting this error: "Trying to access file_column, but primary key got lost." Thanks in advance -- Posted via http://www.ruby-forum.com/.

Hey, I''ve gotten file_column to upload a file, drop it in the dynamic directory, but I can''t display the image, the directories repeat themselves: My model: class Person < ActiveRecord::Base file_column :image_url In my view: <%= image_tag url_for_file_column(''person'', ''image_url'') %> HTML generated is this: <img

Hi all, I''m trying to use file_column to upload a picture but I''m getting the following error: "cannot convert nil into String" caused by the last line in FileColumnHelper::url_for_file_column(object_name, method) url << object.send("#{method}_relative_path") I don''t have any images uploaded for existing entries so does this not

Hi, Sebastian Kanthak of the file_column-Plugin wrote once: "is the photo object inside a local variable or an instance variable (e.g. photo or @photo)? url_for_file_column only works with instance variables, like all other active record form helpers. Could this be the problem?" So I''m using file_column in a partial, e.g. <%= render (:partial => "product",

Hi All, I am using the file_column plugin to upload images. The model that I am using is simply called images (id, name, caption - name being the "file" column) and it belongs_to a parent model called books which has_many images. I was able to figure out how to enter the images into the correct model when updating of form of the parent model (books). Now I need to figure out

Can someone please help me with this. I have an Images table :- create table images ( id integer unsigned not null auto_increment primary key, image varchar(200) not null default '''' )ENGINE=InnoDB default CHARSET=latin1; And a car table :- create table cars ( id integer unsigned not null auto_increment primary key, user_id integer unsigned not null, title varchar(100) not

Hello, I''m just starting out with both Rails and Ruby, so I hope this isn''t too simple of a question - but I''ve been struggling to find a solution. I''m using the file_column plugin to handle image uploads and thumbnail generation. In addition, I''ve wrapped the image into a polymorphic table so I can have uploaded images associated with multiple

first off, thanks (a lot!) sebastian for creating this module... I''ve been spending a lot of time in getting file uploads to work. inside a project I''m working on, I''ve got two different models using it... with one of them it''s working just fine. with another, everything works, with the exception of the url_for_file_column helper, which shows

Hi, url_for_file_column @variable, ''name'', takes an instance variable. My question is, what if I don''t want to have to retrieve the instance variable every single time but I have the image id, along with its name with me. Could I contruct that object in a view and pass it to url_for_file_column: <% @picture = Picture.new %> @picture.id = ...

Hi, I correctly see: image_tag url_for_file_column("element", "picture_url", "medium") now I need to make it a link so I''ve used: <%= link_to(image_tag url_for_file_column("element", "picture_url", "medium"), {:controller => "products", :action => "sec_level", :level_id => @element.id}) unless
