- migration scripts.
- seeding.
- knex.
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 recipes.
- have a way to manage ingredients.
- a recipe could have more than one ingredient and the same ingredient can be used in multiple recipes. Examples are "cup of corn flour" or "gram of butter".
- when saving the ingredients for a recipe capture the quantity required for that ingredient as a floating number.
- have a way to save step by step instructions for preparing a recipe.
Hint: Before writing any code, write out all desired tables in the data model and determine all relationships between tables.
Migrations and Seeds
- Write a migration file that creates all tables necessary to model this data
- Write seed files to populate the tables with test data. Hint: Keep your recipes very simple or this step could become extremely time consuming.
Data Access
In addition to the migrations
and seeding
scripts, write a data access file that exports an object with the following functions:
getRecipes()
: should return a list of all recipes in the database.getShoppingList(recipe_id)
: should return a list of all ingredients and quantities for a given recipegetInstructions(recipe_id)
: should return a list of step by step instructions for preparing a recipe
Organize and name your files anyway you see fit.
Stretch Problem
Build the following endpoints. Write any additional data access helpers as needed.
GET /api/recipes/
: all recipes (without details about ingredients or steps)GET /api/recipes/:id/shoppingList
: a list of ingredients and quantites for a single recipeGET /api/recipes/:id/instructions
: a correctly ordered list of how to prepare a single recipeGET /api/ingredients/:id/recipes
: all recipes in the system that utilize a single ingredient
