TypeORM Postgres NodeJs Saving Data ManyToMany - node.js

Question

I have 4 Entities that I set up and I want to save a recipe.
#Entity('recipes')
export class Recipe extends BaseEntity {
#PrimaryGeneratedColumn('uuid')
id: string;
#Column({ type: String, unique: true })
recipe_name: string;
#Column({ type: String })
description: string;
#OneToMany(() => RecipeIngredientList, (r: RecipeIngredientList) => r.recipeId)
recipeLists: RecipeIngredientList[];
}
#Entity('measurements')
export class MeasurementUnits {
#PrimaryGeneratedColumn()
id: number;
#Column({ type: String })
unit: string;
#ManyToMany(() => RecipeIngredientList, (r) => r.unitID, { cascade: true })
recipeList: RecipeIngredientList[];
}
#Entity('ingredients')
export class Ingredient {
#PrimaryGeneratedColumn()
id: number;
#Column({ type: String })
ingredient_name: string;
#ManyToMany(() => RecipeList, (r: RecipeList) => r.ingredientID, { cascade: true })
recipeList: RecipeList[];
}
#Entity('RecipeIngredientList')
export class RecipeIngredientList{
#PrimaryGeneratedColumn()
id: number;
#Column({type:Number})
amount: number;
#ManyToOne(() => Recipe, (r) => r.recipeLists)
recipeID: Recipe;
#ManyToMany(() => Ingredient)
#JoinTable()
ingredientID: Ingredient[];
#ManyToMany(() => MeasurementUnits)
#JoinTable()
unitID: MeasurementUnits[];
}
//My Save Method() The getDatabaseConnention() is in a service I wrote to
// check/connect via the DataSource.manager
const create = async (recipe: Recipe): Promise<Recipe> => {
const recipeRepository = await (
await getDatabaseConnection()).getRepository(Recipe);
const newRecipe: Recipe = await recipeRepository.save(recipe)
.catch((e) => {
console.debug('failed to create recipe Record', e);
throw new Error(e);
});
return newRecipe;
};
The effect of this is its creating the 6 tables in Postgres as expected but its only saving to the main recipes table and not able to save any of the relations. Am I missing foreignKeys or constraints in my entity setup? Or is my save method not properly identifying the relationships?
Now I know the way I have the DB setup the RecipeIngredientList Table is going to be the work horse and has a potential to get bloated, but I think this is a decent setup for a recipe management (I removed a lot of metadata to not bloat the post).
