An example of an AI chatbot conversation about Flask-SQLAlchemy relationship types.
What are the different types of relationships in Flask-SQLAlchemy?
In Flask-SQLAlchemy, there are several types of relationships: one-to-one, one-to-many, and many-to-many.
Can you explain the one-to-many relationship with an example?
Sure! In a one-to-many relationship, one record in a table can be associated with multiple records in another table. For example, a user can have multiple posts.
How do I implement a many-to-many relationship?
To implement a many-to-many relationship, you need an association table that links the two tables. For instance, if you have students and courses, a student can enroll in many courses and a course can have many students.
What are some common pitfalls when working with these relationships?
Common pitfalls include not properly defining foreign keys, forgetting to create association tables for many-to-many relationships, and not handling cascading deletes correctly.
