Mongo DB in Flask Demo

Covers basic CRUD operations using pymongo, and connecting to a MongoDB client.

Challenges

• 1. Create a clear post route that deletes everything
• 2. Format the dates in Month, Day, Year format using your model.py and the datetime library

Key Points

• After a POST request, use redirect("/route") instead of render_template() if you want your user to navigate to another page.
• The general format of a mongoDB entry is:

{
    "field_name" : "field_value",
    "field_name_2" : "field_value_2",
    ...
    "field_name_n" : "field_value_n"
}

• A query is/are field(s) and value(s) used to look up entries with matching field(s)/value(s), e.g {"date" : "12-23-08"}
• Your CRUD operations are
  • (CREATE) insert_one(entry) and insert_many(entries),
  • (READ) find_one(query) and find_many(query),
  • (UPDATE) update_one(query, new_val) and update_many(query, new_val),
  • (DELETE) delete_one(query) and delete_many(query).
• You can use loops in Jinja3 with {% statement %}.
