Ruby Question

Check a value before saving

I'm trying to implement a condition in my form which say

if cat:(integer)=1 @post.update(father: "lolo")


I'd try put this into my create action, and too into a before_save but is not working. So if you have any ideas to solve this, you're welcome !!

My code :

Option 1 (into the create action)=

if @self.cat = 1
@cycle.update(father: "lolo")
end


Option 2 (before_save action )

before_save :check_cat

def check_cat
@cow = self.cow
if @cow.cycles.any?
self.update(father: "lolo")
end
end

Answer Source
if @self.cat = 1

You are using assignment in if operator. Must use comparison. Read this for details: https://www.tutorialspoint.com/ruby/ruby_operators.htm

in short must be

if @self.cat == 1
