INITIAL PUSH: Project setup with dependencies, folder structure, basic code. Added margin notes.

The endpoint path should just be /, unless it was intentional to have the complete path be /api/budget/budget.

The value we're passing into new Category should be a JSON object. Currently, we're passing in a string. Simple fix would be to change it to:

const category = new Category(req.body)

[frankfaustino]

In this route, we should be fetching budget and category with the findOne method. Then using Promise.all, we grab the ObjectId for each from the response from MongoDB. Then create our new Expense.

.post((req, res) => {
  let { amount, budget, category, description } = req.body

  budget = Budget.findOne({ title: budget })
  category = Category.findOne({ title: category })

  Promise.all([budget, category])
    .then(([budget_id, category_id]) => {
      const expense = new Expense({
        amount,
        budget: budget_id,
        category: category_id,
        description
      })

      expense.save()
        .then(response => res.status(201).json(response))
        .catch(err => res.status(500).json(err))
    })
    .catch(err => res.status(500).json(err))
  })

By doing the above, we can now send a POST request from Postman that looks like this:

{
	"amount": 35,
	"description": "potatoes",
	"budget": "Monthly Spending",
	"category": "Groceries"
}
