Many to many tables loss

[whygee-dev]

const generateModels = (
    manyToManyFields: DMMF.Field[],
    models: DMMF.Model[],
    manyToManyTables: DMMF.Model[] = []
): DMMF.Model[] => {
    const manyFirst = manyToManyFields.shift();

    if (!manyFirst) {
        return manyToManyTables;
    }

    const manySecond = manyToManyFields.find((field) => field.relationName === manyFirst.relationName);

    if (!manySecond) {
        return manyToManyTables;
    }

    manyToManyTables.push({
        dbName: `_${manyFirst.relationName}`,
        name: manyFirst.relationName || '',
        primaryKey: null,
        uniqueFields: [],
        uniqueIndexes: [],
        fields: generateJoinFields([manyFirst, manySecond], models),
    });

    return generateModels(
        manyToManyFields.filter((field) => field.relationName !== manyFirst.relationName),
        models,
        manyToManyTables
    );
};

manyToManyFields.shift() mutates the manyToManyFields array and leads to the non-mapping / partial loss of many to many tables in some cases
