Prerequisites

• Python version 3.9 or above
• Pickle
• IDE (VS Code, PyCharm, Thonny etc.)

Installation

python -m pip install mini_pickle_db

Usage

Here is how to framework actually functions:

1. Initial steps:

from mini_pickle_db.pickle_db import db

1.1. You can initiate the database class using the:

  database = db()

1.2. You should specify the file path of the database document as shown below:

  database.db_file = 'file_path'

Note: The Wrapper will automatically create the file, but not the folder, so one must be created manually.

2. Document Structure:

2.1. The documents follow a simple Python dictionary format as shown below:

  example_doc = {
    "key_1": "value_1",
    "key_2": "value_2"
    }

3. Database Usage: 2.1. How to insert a single document in the database:

single_doc = {
"key_1": "value_1",
"key_2": "value_2"
}
db.insert(single_doc)

2.2. How to insert multiple documents in the database:

multiple_docs = [
  {
      "key_1": "value_1",
      "key_2": "value_2"
  },
  {
      "key_3":  "value_3",
      "key_4":  "value_4"
  }
]
db.insert(multiple_docs)

Note: The database automatically assigns an ID to every document and is autoincremented.

  [
    {"key_1": "value_1", "key_2": "value_2", "id": 0}, 
    {"key_1": "value_1", "key_2": "value_2", "id": 1}
  ]

Note: The data type of the multiple document database is a list of dictionaries.

2.3. How to load the database:

  database.load()

Note: It returns a list of dictionaries.

2.4. How to query the database:

2.4.1. Query a single document:

  database.query_one({'key_2': 'value'})

Note: It will return only the first document it finds.

2.4.2. Query a multiple documents:

  database.query_many({'key_2': 'value'})

Note: It will return all the documents matching the querry in a list format.

2.5. How to delete document:

  database.delete({'key': 'value'})

Note: It will delete all the documents matching the querry in a list format. For more examples, please refer to the Documentation
