Question about file_column plugin
Hi!
File_column plugin saves uploaded files to
"public/model/image/model_id/filename", if i understand it correctly.
Does it mean that it creates new folder for every image?
I have product (model) that has_many images (model). Is it possible to
use (or modify) this plugin that it would save my images to different
folder, so the id of the model_id part would be id of the product

RoR - getting started with database relations
Hey everyone... I''m just getting my feet wet with relational databases

simple question
How do I pass parameters from one controller to another during
redirect_to command? I want to pass both model and non-model objects.
The solution I use is via session, but I rather pass it as parameters to
the redirect_to

.build method
I have gone to the api and have searched the internet and looked
through the books that I have, but I am having trouble finding an
explanation on what the .build method actually does and how it is
used.
I guess the best example is if I want to create a todo list
application where I can create a new todo list and add to do items all
at the same time.
I would post to the todolist controller to

This doesn't work, because FUN is a function. I've already tried to

Extracting subset from netCDF file using lat/lon and converting into .csv in R
Two questions:
1. Is the order of the dimensions shown what is shown if you look at str(ncin) - I mean shown at the end where it describes the variable and its dimensions?
2. Is you problem how to subset the netcdf file, how to write to the .csv file, or both?
