I'm building a Rails (4.1.8) application with Postgres (0.18.3), Rspec (3.1.0), and FactoryGirl (4.5.0). I need help troubleshooting a controller test, which is throwing an Active Record::AssociationTypeMismatch error caused by a FactoryGirl object.
Here's my Fitness goals controller index action:
def index
@fitness_goals = @member.fitness_goals.order(:start_date)
end
This is my set-up and test of the fitness goals controller index action (fitness_goals_controller_spec.rb):
RSpec.describe FitnessGoalsController, :type => :controller do
let(:member_attributes) { {
"first_name" => 'Joe',
"last_name" => 'Smith',
"sex" => 'Male',
"age" => 30,
"height" => 69,
"weight" => 187,
"goal" => ["Lose Fat"],
"start_date" => Date.current
}
}
before :each do
@request.env["devise.mapping"] = Devise.mappings[:user]
@user = FactoryGirl.create(:user)
sign_in @user
@member = @user.build_member member_attributes
@member.save
@fitness_goal = FactoryGirl.create(:fitness_goal, member: @member)
@fitness_goal_attributes = FactoryGirl.build(:fitness_goal).attributes
@fitness_goal_invalid_attributes = FactoryGirl.build(:fitness_goal, timeframe_id: nil).attributes
@fitness_goal_update_attributes = FactoryGirl.build(:fitness_goal).attributes
@fitness_goal_update_invalid_attributes = FactoryGirl.build(:fitness_goal, timeframe_id: nil).attributes
end
describe "GET index" do
it "assigns all fitness goals as @member.fitness_goals" do
get :index, { :member_id => @member }
expect(assigns(:fitness_goals)).to eq(@member.reload.fitness_goals)
end
end
The rspec error and backtrace:
1) FitnessGoalsController GET index assigns all fitness goals as @member.fitness_goals
Failure/Error: @fitness_goal = FactoryGirl.create(:fitness_goal, member: @member)

The error references the Target model, a has_and_belongs_to_many (HABTM) association with the Fitness Goal model: Target(#62887900) expected, got String(#8489780)
The relevant models:
class FitnessGoal < ActiveRecord::Base
has_and_belongs_to_many :targets
end
class Target < ActiveRecord::Base
has_and_belongs_to_many :fitness_goals
end
The join table in schema:
create_table "fitness_goals_targets", id: false, force: true do |t|
t.integer "fitness_goal_id"
t.integer "target_id"
end
Fitness goal params:
def fitness_goal_params
params.require(:fitness_goal).permit(:goal_list_id, :timeframe_id, :start_date, :end_date, { target_ids: [] }, { activity_ids: [] }, :notes, :member_id, :trainer_id)
end
Fitness Goal factory:
FactoryGirl.define do
factory :fitness_goal do
association :goal_list
association :timeframe
start_date Date.current
end_date Date.current + 30
targets ["Lose Fat", "Reduce caloric intake by x%"]
activities ["Walk x steps a day", "Climb x floors a day", "Run x miles a day"]
association :member
association :trainer
notes 'This is a sample note.'
end
end
What am I doing wrong? The application code works as expected in both development and production environments. It appears the problem is somewhere in my set-up for the FactoryGirl object. Implementing the HABTM association is what broke the controller test. How do I fix the issue and get the controller test passing again? Thanks for any help!
