Hello, I am trying to run the following model: domi ~ type*ratio+((1|id)+(0+type|id)+(1|face_id)+(1|car_id)) My question is whether the data coding for "face_id" and "car_id" variables is correct. As you see on the following sample data structure, "type" is repeated measure where 1=car, 0=face. Thus, I coded "face_id" as "0" when the type is 1

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

I''m using Windows and Postgres 8. I installed RMagic gem thingy and FileColumn plugin ok. I followed instructions exactly as directed on FileColumn web site which is very straight forward: ---model class My_model < ActiveRecord::Base file_column :column_for_file_name end -----view -upload form--set to mulitpart <%= file_column_field "my_model",

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?

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

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.

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...

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
