#506 - Add Database Layer to Support Scaling - @hay-kot

[hay-kot]

I've gone through and added the database layer for the required fields. There is both a Foods and Units field where the foods are things like Carrots or Onions and Units are like Cups or Oz. I've also added the following behavior

• When creating a Recipe Pydantic Model if it's a list of strings it will be converted to the new schema by passing the string as the notes field. This will allow backups/restores to happen seamlessly.
• By default, all ingredients default to amount_disabled=True this behavior results in only the notes section being shown. This will retain the simplicity for users who don't care about recipe scaling.
• Shopping lists now pull the notes field out of the ingredient. This will need to change in the future. Likely a whole rewrite of the shopping list is necessary to provide adequate merging of ingredients.
• I've also generated some skeleton routes that don't do anything yet for the Food/Units that will be required for the CRUD functionality through the API.

I'm going to be leaving this for a while to work on tests but this should be a good starting point.

Is it considered that we would like halve the recipe. currently, if a cake is made for example, with 8 portions. There is no option to scale it down to let's say 6 servings. Although, this is only a rule of three.

@zierbeek that's not a use case I'm considering.

@hay-kot I have the same request. But it's already said in the discord. Several people use it for non baking and there it's logical that you can scale down or up with a increment of one. Maybe an option to add to a recipe that it can be scaled down or something?

[mjmccans]

For what it is worth, I too would really appreciate being able to scale below one or be able to scale up by a fraction (e.g., 1.5 the recipe). I am not a great cook so I may be missing reasons why this would not work, but I often scale my recipes by fractional amounts and allowing this feature would save me doing some math. Either way, I am really enjoying the program and thank you for all of the effort!

Hey folks, closing this issue since the initial support is now baked into Mealie v1. As far as the scaling down - it's not something I'm going to look at but happy to look at a feature request and/or a PR to add it.
