Assignment
Design the data model for a recipe book application, then use Knex migrations and seeding functionality to build a SQLite3 database based on the model and seed it with test data.
The requirements for the system, as stated by the client are:
- have a way to manage dishes. A dish is something the client wants to cook like pizza or tacos.
- have a way to manage recipes. A dish can have different recipes for tacos, like tex- [ ]mex or granny's. A recipe belongs only to one dish.
- have a way to manage ingredients.
- a recipe could have more than one ingredient and the same ingredient can be used in multiple recipes.
- when saving the ingredients for a recipe capture the quantity required for that ingredient.
- have a way to save instructions for cooking a recipe. Instructions will be a series of steps involved in cooking a recipe. For some recipes, the order in which the steps are performed matters, so we should provide a way to specify that.
- have a way to pick a dish and a recipe and get a shopping list with all the ingredients, and quantity of each, needed to cook the dish.
In addition to the migration and seed scripts write a data access library that publishes the following API:
-
getDishes()
: should return a list of all dishes in the database. -
addDish(dish)
: should add the dish to the database and return the id of the new dish. -
getDish(id)
: should return the dish with the provided id and include a list of the related recipes. -
getRecipes()
: should return a list of all recipes in the database including the dish they belong to. -
getRecipe(id)
: should return the recipe with the providedid
. The recipe should include:- name of the dish.
- name of the recipe.
- the list of ingredients with the quantity.
- the list of steps in the order they need to be executed.
-
addRecipe(recipe)
: should add a recipe to the database and return the id of the new recipe.
Extra Credit
- follow the same pattern to add the CRUD operations for other entities in the system.
- add units of measure support for the ingredients.
- add a table of unit of measure convertions, so that we can record the quantity for an ingredient using a unit of measure.
