Ruby on Rails syntax question

Question

I am super new to RoR. I am currently working on these interesting Rails exercises for Zombies. And I'm stuck on some syntax issues ...

My code is:

Weapon.where(:zombie => "Ash")

But that will not work. If instead I typed:

Weapon.find(1)

I passed (since the first weapon belongs to the zombie Ash).

My question is: what happened to my answer using this .where () method?

Thanks in advance.

Answer 1

You should have enclosed the request as follows:

Weapon.where(:zombie => {:name => "Ash"})

This will give you a zombie weapon whose name is "Ash"

Weapon.where(:zombie_id => z)

Answer 12

Weapon.whe­re(:zombie­_id => Zombi­e.where(:n­ame => "Ash"­))

DB Weapon, zombie_id, - Ash DB Zombie.

Answer 13

, Weapon.find(1), , , : id = > 1, , .

Zombie.find(1).weapons, , : id = 1, , , : name, : id.

"where", - @edgerunner, :

#<ActiveRecord::StatementInvalid: SQLite3::SQLException: no such column: zombie.name: SELECT "weapons".* FROM "weapons" WHERE "zombie"."name" = 'Ash'>

so I'm not sure if this is a limitation through the program or what - as it is, I'm still a little confused.

Answer 14

answers Zombie.find(1).weapons.. then you will be able to find all the weapons Ash.
