| GOAL: | |
| To create a database of liquor in your liquor cabinet, and a database of possible drinks to make. | |
| Output: | |
| (1) a list of drinks you can make with your existing liquors, (hard!) and | |
| (2) a list of drinks you could make if you just bought a few more things | |
| === | |
| Views that currently exist on the DB: https://gist.github.com/1128805 | |
| (the "view_recipes_in_cabinet_using_all_ingredients" isn't quite right - it only matches a recipe that has YOUR ENTIRE cabinet in it, not a non-exclusive subset) | |
| Data setup: | |
| table users -- The user database | |
| users.identity = unique ID | |
| table liquors -- A generic list of alcohol | |
| liquors.id = unique ID | |
| liquors.name = plaintext name | |
| table liquorCabinet -- This is "your stockpile of liquor" as a user | |
| liquorCabinet.userID = users.identity | |
| liquorCabinet.liquorID = liquors.id | |
| table recipes -- A list of possible recipe (drink) names | |
| recipes.id = unique ID | |
| recipes.name = plaintext name | |
| table recipeIngredients -- The list of recipes | |
| recipeIngredients.recipeID = recipes.id | |
| recipeIngredients.liquorID = liquors.id | |
| ==== | |
| Some sample data: | |
| A single user (users.identity = 1) has two things in his liquor cabinet: | |
| liquorCabinet.userID = 1 liquorCabinet.liquorID = 1 | |
| liquorCabinet.userID = 1 liquorCabinet.liquorID = 2 | |
| that corresponds to | |
| liquors.id = 1 liquors.name = Vodka | |
| liquors.id = 2 liquors.name = Tequila | |
| There are two recipes in the system: | |
| recipes.id = 1 recipes.name = Shot o' Vodka | |
| recipes.id = 2 recipes.name = Gross Mix | |
| Which correspond to: | |
| recipeIngredients.recipeID = 1 recipeIngredients.liquorID = 1 | |
| recipeIngredients.recipeID = 2 recipeIngredients.liquorID = 1 | |
| recipeIngredients.recipeID = 2 recipeIngredients.liquorID = 2 | |
| As it stands, this user can build both recipes as he has all of the necessary required liquors. |
