I know this blog has been dormant for quite some days now for no apparent reason. But I would like to share what I learnt today. This is going to be in Rails (2.3.x) and hardly interest anyone who already knows it. But it still was a learning to me. I use to hate working in command prompt and was an IDE freak, a real good one too. But I was cornered to learn more on the command line front as well. Why waste an extra feather in the cap?
Bulling the shit, here is what I learnt today.
Rails has a script/generate ready for many usual stuff that we do. One of them is the model generator. It is not that much, but I was wondering whether it is possible to create associations using it. And I found it is not.
I tried a stupid model generation something like (in fact exactly like this)
It reeked,
My stupid assumption was that it would actually create a couple of models called projects and tasks. But to my wonder, it did not. The highlight was this command did not even raise any error. Inspecting the database migration, I found
And I did a migration and it did migrate without any errors. It silently ignored the line t.tasks :has_many. Not usual right?! But this is rails, you got to adapt and adapt very well. One more learning probably I could share are the commands that come with the script/generate model is the --pretend. This is like a dry run, does not actually creates a physical file but tells what its going to do. Thats it for today.
