Changes for Revision 1

• Use DB Migration files that can be PR'd.
• Improve naming conventions to be more consistent, i.e Id
• Use Django forms for filtering views.
• Use Text field for model fields with very large lengths.
• Create Email template model.
• Implement email blurb construction.
• Setup Email Backend to print to console.
• Ensure that validation checks follow fail-fast by checking base cases.
• Investigate using get_object_or_404 (Removed due to not being consistent with the rest of the view/model approach).
• Ensure that all get functions on models have a try/except for when the entry does not exist.
• Update presigned_url to upload_id to make more descriptive.
• Dynamically build out upload and download URLs using request information.
• Use a base model and inherit for created_at.
• Update Model on_delete for foreign keys to SET_NULL where data retention would be necessary.
• Updated all Enums to use Django Integer choices for consistency.
• Switch upload_id to text to allow easy changing of type and not being locked to UUID.
• Streamlined logic to check whether an upload_id is valid in utilities.
• Research Fat Model / Skinny view vs. Skinny Model / Fat View (The approach in this project is Skinny Models to separate the business and data access logic).
• Create a form for Document Creation requests that is reused by the Documents and Customers View.
• Some general code cleanup and updates to ensure consistency in the project.
