ruby on rails - Why would a truthy check on an enum value not work like I expect? -

on membership model, have following enum value:

enum relative_type: { member: 0, user: 1 } 

then elsewhere in code, when comes upon membership model, have if-branch

      if membership.user?         member = member.create(first_name: self.first_name, last_name: self.last_name, email: self.email, bio: self.bio, gender: self.gender, avatar: self.avatar, birthday: self.birthday, deceased: false)         membership.update!(member: member, invited: nil, relative_type: 0)         binding.pry         membership.inviter_connection.update!(request_status: 3)       end 

the weird thing attributes membership.user? returns false, execution still gets passed inside if block.

here example of pry session.

    207:           if membership.user?     208:             member = member.create(first_name: self.first_name, last_name: self.last_name, email: self.email, bio: self.bio, gender: self.gender, avatar: self.avatar, birthday: self.birthday, deceased: false)     209:             membership.update!(member: member, invited: nil, relative_type: 0)  => 210:             binding.pry     211:             membership.inviter_connection.update!(request_status: 3)     212:           end     213:         end     214:       else     215:   [1] pry(#<user>)> membership.user? => false [2] pry(#<user>)> membership => #<membership id: 11045, family_tree_id: 76631, user_id: 31643, created_at: "2016-02-06 08:16:54", updated_at: "2016-02-06 08:18:08", relation: "brother", member_id: 9872, invited_id: nil, relative_type: 0> [3] pry(#<user>)> membership.relative_type => "member" [4] pry(#<user>)> membership.member? => true 

so membership object above, can see membership.relative_type equal 0, corresponds member. works expect, particularly given membership.member? returns true.

what don't understand is....in current instance, why on earth instance of pry being executed within if block should executed if membership.user? true....yet false here.

the weird thing edited method more explicit, so:

if membership.user? == true

but still sends execution if-block when membership.user? false.

    207:           if membership.user? == true     208:             member = member.create(first_name: self.first_name, last_name: self.last_name, email: self.email, bio: self.bio, gender: self.gender, avatar: self.avatar, birthday: self.birthday, deceased: false)     209:             membership.update!(member: member, invited: nil, relative_type: 0)  => 210:             binding.pry     211:             membership.inviter_connection.update!(request_status: 3)     212:           end     213:         end     214:       else     215:   [1] pry(#<user>)> membership.user? => false [2] pry(#<user>)> membership.user? => false [3] pry(#<user>)> membership.member? => true

i took step further , compared actual values of enum, so:

    207:           if membership.relative_type == 'user'     208:             member = member.create(first_name: self.first_name, last_name: self.last_name, email: self.email, bio: self.bio, gender: self.gender, avatar: self.avatar, birthday: self.birthday, deceased: false)     209:             membership.update!(member: member, invited: nil, relative_type: 0)  => 210:             binding.pry     211:             membership.inviter_connection.update!(request_status: 3)     212:           end     213:         end     214:       else     215:   [1] pry(#<user>)> membership => #<membership id: 11049, family_tree_id: 76639, user_id: 31647, created_at: "2016-02-06 08:41:59", updated_at: "2016-02-06 08:42:02", relation: "brother", member_id: 9874, invited_id: nil, relative_type: 0> [2] pry(#<user>)> membership.relative_type => "member" 

but still no dice.
