Rails: Getting Previously Defined Traits in a Factory

I have the following factory:

FactoryGirl.define do
  factory :group_member do |f|
    f.user_id { rand(1..100) }
    f.group_id { rand(1..100) }
    f.membership { ["accepted", "invited", "declined", "requested", "denied", "left", "removed"].sample }
    if "#{membership}" == "accepted"
        f.host { [true, false].sample }
    else
        f.host false
    end

  end
end

The line:

if "#{membership}" == "accepted"

is throwing the error:

Trait not registered: membership

My intention is to find out if the previously defined trait "membership" is set to "accepted." I'm not sure how to access that trait, however. Any tips?

On another note, factory creation resembles form creation, in so far as there's a variable ('f' in this case) which is assigned various traits. Is there a word to describe these types of code blocks?

UPDATE: I've changed the factory to use an after_build call, but now I'm getting this error:

undefined method `after_build=' for #<GroupMember:0x5dcb328>

The updated code looks like:

FactoryGirl.define do
  factory :group_member do |f|
    f.user_id { rand(1..100) }
    f.group_id { rand(1..100) }
    f.membership { ["accepted", "invited", "declined", "requested", "denied", "left", "removed"].sample }
    f.after_build do |obj|   
        if obj.membership == "accepted"
            obj.host = [true, false].sample
        else
            obj.host = false
        end 
    end

  end
end

Re: Checking values already set.

f.after_build do |obj|   
  # Test your obj.membership here. 
end

Re: The error message complaining that after_build doesn't exist.

Your definition syntax looks off. Change this:

FactoryGirl.define do
  factory :group_member do |f|

to this:

FactoryGirl.define :group_member do |f|
