  • Wouldn't it be more correct to store not the books on the side of the author but the authors of each book on the side of a book?
    One author might have dozens of books written, one book has for the greater part a single author

  • what if I store only id's

  • This is a good example if you know the book will never share an Author. In that case, this wouldn't be the best schema because if 100 authors each co-authored a book (all 100 authors have the same book in their record), and you realize you need to update/change something about the book, you can't just edit the book once. You have to iterate over each author and update the book. TL:DR; Just because something is relational, doesn't mean you always follow this schema

  • Hi The net ninja, is this model OK if I want to search book by genure? Pls suggest me how to search

  • This works for one-to-one or one-to-many relationships. What about many-to-many relationships? Say a book has two authors? In that case I'd have to insert the book data twice (once against each author).

  • But if we have another document that also uses books, what can we do? Replicate the data?

  • @The Net Ninja

    If we have many transactions for Books, is it better to separate Books as a different collection and set relation with object_id?

  • what i dont get is how you would easily say a book that has more than one author. Would you have to make a new book object for each author?

  • I don't trust a coder who uses a variable-width font in his editor.

    Isosceles Kramer July 4, 2020 8:32 am Reply
  • Can we dynamically assign dynamic reference where you assigned bookSchema to autorSchema?
    For example, let's say we want to make creativePeopleSchema which has Name age and creation as fields. so the question is can we reference movieSchema or bookSchema or paintingSchema to creativePeopleSchema via creation field????
    (PS: I have a completely different problem but in this context, we can use this as an example to my problem )

  • Hi Net Ninja, How can I use this schema for storing array of objects coming from frontend API(using angular reactive forms for creating array of objects)?

  • Sad that you are using mongoose. MongoDB is great for its flexibility, mongoose is a killer of that principle.

  • This works for me, but I get an error when I import those subdocuments, i.e. storing them in other folders.

  • So what are the performance implications if you want to get a list of all books? Not just the books of a single author?

  • FYI your audio is very quiet. I had to put my volume up 300%, which made everything else on my computer explode my apartment.
