How to pass hash method rspec to controller - ruby-on-rails

Question

Using Rails 5.1.4, Ruby 2.4.1, rspec
Scenario:
In article destroy allow only user current_ma_user with role "a,m"
Then:
Check if current_ma_user.role = "a,m"
or current_ma_user own article (#article.user)
So I create current_ma_user as hash as well as user.
Then call role to check what is user[role ]
Problems:
How to add new method to hash.
How to pass that hash.method from rspec controller_spec to controller.
Failures:
1) ArticlesController DELETE #destroy destroys the requested article
Failure/Error: delete :destroy, params: {id: article.to_param}, session: valid_session, :current_ma_user.role => "a,m"
NoMethodError:
undefined method `role' for :current_ma_user:Symbol
# ./spec/controllers/articles_controller_spec.rb:172:in `block (4 levels) in <top (required)>'
# ./spec/controllers/articles_controller_spec.rb:171:in `block (3 levels) in <top (required)>'
This is the gist
articles_controller_spec.rb:
require 'rails_helper'
RSpec.describe ArticlesController, type: :controller do
class Hash #patch to temp pass problem 1
def role
"a,m" #Hard Code, need to call user["role"] need code
end
end
user = {}
user["uid"] = "admin"
user["provider"] = "Facebook"
user["email"] = "1.0#kul.asia"
user["role"] = "a,m"
current_ma_user = user
describe "DELETE #destroy" do
it "destroys the requested article" do
article = Article.create! valid_attributes
expect {
delete :destroy, params: {id: article.to_param}, session: valid_session
}.to change(Article, :count).by(-1)
end
it "redirects to the articles list" do
article = Article.create! valid_attributes
delete :destroy, params: {id: article.to_param}, session: valid_session
expect(response).to redirect_to(articles_url)
end
end
end
Controller:
class ArticlesController < ApplicationController before_action :load_article, only: [:show, :destroy]
def destroy
if current_ma_user.role.upcase.split(',').include?("A") || current_ma_user == #article.user
#if current_ma_user == #article.user
#article.destroy
end
redirect_to :action=>'index' end
private
def load_article
#article = Article.find(params[:id]) end
end
Updated with line number:
Updated debug to show value of current_ma_user in .spec and controller

This is where your error is coming from (in your controller):
if current_ma_user.role.upcase.split(',').include?("A") || current_ma_user == #article.user
Suggested Solutions
Where is current_ma_user defined in the controller? (if it’s not assigned, then it needs to be assigned before you call the role method on the current_ma_user variable.
Try that and see how it goes.
Do something like this:
current_ma_user = User.find( params[:user_id])
Now you seem to want to pass something into the params hash. Remember to white list whatever you decide to pass into params. Whether it is user id or roles id etc, or a roles string.
When writing your tests, pass in the approrpiate values to the params hash. If you are passing in a user_id in your test, then you will have to make sure that a user is created in the test.
delete :destroy, {:id => article.id.to_s, :user_id => #current_ma_user.id }, session: valid_session
also perhaps in your spec file, in your test, put the current_ma_user in a before filter and make it an instance variable so it will be accessible to all your tests:
before(:each) do
#current_ma_user = user.create( <--- create the user with the
appropriate attributes here --->)
end
