This article is basically a follow-up of my previous article: Teng::Row and data2row.
As of Teng Ver. 0.21, data2row is implemented as Teng#new_row_from_hash. I already introduced a way how I used this method on my previous article, so I am going to introduce 2 different usages.
The first example describes how to cache column values and then creates table row object with cached values. With Devel::Size I compared the size of row object and column values then I realized that the size of row objects become much bigger. So my idea is to cache only the column values to minimize cache size and then create table row object with the cached values.
The Second example shows how I utilize the table row object's method by creating temporary object. In this case I'm trying to upload image to a certain path and the path is generated based on the filename and campaign_type. I didn't want to generate path in 2 places, but instead I wanted to generate it at one place so I'm not going to mess up by modifying one and forgetting modifying the other.
I like the way Teng enables me to do this kind of things easier.
