Calling url_for_file_colum results in a TypeError: can''t convert nil to string. The error is in line 148 of filecolumn.rb: def relative_path(subdir=nil) File.join(relative_path_prefix,subdir, @filename) end If I substitute '''' for subdir in the File.join command, then it seems to work fine. Since this is a plugin, I''m wondering why I need

Hi, I''m using filecolumn to upload a file to mysql blob : _form.rhtml : file_column_field "entry", "attach" model (rb file) : file_column :attach How can I update controller create function to insert file in database ? redefine model save function ? Someone has a sample source ? Regards, Fabian

I have a file uploader application in ROR using the very nice FileColumn plugin. In looking at the source code I can see that there is a DEFAULT_OPTION hash with some root path options and such which can be merged from an options paramater. These static path changes are not a problem. My question is dynamic path options. My upload form, when you boil it down, has two fields. The first is

Hi I have this filecolumn: file_column :file, :magick => { :versions => { :large => ''756x567>'' } } Does anybody have a solution to make this also accept files that aren''t images? Now this makes filecolumn return an error of "File invalid image" if the file isn''t an image. Would be nice if it, when the file is invalid image, just

i''ve changed store_dir to :store_dir => "public/uploads/users/pictures/" that works great for uploading, but url_for_file_column is still outputting: /user_picture/image/id/name.jpg how do i make url_for_file_column output the correct url? -- Posted via http://www.ruby-forum.com/.

Is there a way to find out the attributes that have been passed to file_column in models? I''ve looked through the source and it seems that the file_column methods are generated at runtime but there''s actually no class or instance variable that hold the file attribute. -------------- next part -------------- An HTML attachment was scrubbed...

I was looking at Kyle Mawell''s extremely nifty-looking StateModels plugin http://www.kylemaxwell.com/articles/2006/02/06/fun-with-single-table-inheritance and before I go down the road with it, I was wondering if anyone has used it with file_column. The way file_column deals with an uploaded file -- by storing it to the filesystem in a path that employs the model name and id --

I installed FileColumn successfully but now find the need to get a new image size. I was wondering if there was a fast script, or method, that would run through all my products and use the existing mail file already submited and resize it according to the new specifications.

Hi all: I want to fit a multinomial logit model with VGAM package, however I cannot find a way to check the residuals since residuals(my_model) and resid(my_model) does not work. Any suggestions? Thanks in advance. Alex Brito [[alternative HTML version deleted]]

Hi, I am using file_column for some image uploading. I want to have all the images stored under one root which I have managed by setting the :store_dir option as below. file_column :filename, :store_dir => File.join(RAILS_ROOT, ''public'', ''images'', ''products'') So, my images get uploaded to: /public/images/products/<primary_key>

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

Hi, I was trying to draw some ROC curves (prediction of case/control status), but seem to be getting a somewhat jagged plot. Can I do something that would 'smooth' it somewhat? Most roc curves seem to have many incremental changes (in x and y directions), but my plot only has 4 or 5 steps even though there are 22 data points. Should I be doing something differently? How can I provide a

One of my models has a column that is updated very frequently from a separate process, so it is important that when a record is saved in rails, this column should be left alone. In the update method of the controller I have: @record = MyModel.find(params[:id]) @record.update_attributes(params[:my_model]) params[:my_model] doesn''t have a reference to the column I''m talking

Hi, I have problem accessing the testfixture. The values from the YML-Fixture-File are correctly written into database, but accessing the fixture is impossible. It is always nil. Is anything wrong with this test? class MyModelTest < Test::Unit::TestCase fixtures :my_model def test_simple a = MyModel.find(@my_model["first"].id) # Accessing @my_model is impossible ...

Hello, I generated a controller, using the command: ruby script/generate controller my_kontroller my_model The generated controller file, however, contains an empty class definition. The default controller code is missing. Any idea what went wrong? Thanks, gk -- Posted via http://www.ruby-forum.com/.

Hello All, I''m using FileColumn to store images for a model in my app. I use filecolumn to scale uploaded images to different sizes. This much works fine. I then created a Ruby class for annotating text on the uploaded image. I tested this class from the shell and it works as expected. I then created a plugin for this class and hooked it up to the model. Here''s where I start

Hi, I run R 2.10.1 under ubuntu 10.04 LTS (Lucid Lynx) and klaR version 0.6-4. I compute a model over a 2 classes dataset (composed of 700 examples). To that aim, I use the function NaiveBayes provided in the package klaR. When I then use the prediction function : predict(my_model, new_data). I get the following warning : "In FUN(1:747[[747L]], ...) : Numerical 0 probability with
