Documentation Management: Implement CRUD Functionality

Hey guys! Let's dive into how we can implement a full CRUD (Create, Read, Update, Delete) section for managing documents. This is all about giving admins the power to upload PDFs, view what's already there, tweak things, and remove stuff when needed. We will cover both the backend (routes.py) and the frontend aspects to ensure a seamless experience.

📄 Description

The goal here is straightforward: build a robust system for document management. Think of it as giving admins the keys to the kingdom when it comes to handling important files. They should be able to add new documents (uploading PDF files), see what’s already available, make changes, and delete documents that are no longer needed. This functionality is crucial for maintaining an organized and up-to-date repository of information. This system ensures that the right documents are always accessible, properly managed, and easily updated, saving time and reducing the risk of outdated information being used. A well-designed document management system also enhances collaboration, as team members can quickly find and share relevant documents, streamlining workflows and improving overall efficiency. Moreover, it provides a centralized location for all important files, making it easier to track document versions, manage permissions, and ensure compliance with organizational policies and regulatory requirements. Ultimately, a robust document management system is a cornerstone of efficient and effective business operations, supporting informed decision-making and fostering a culture of transparency and accountability.

⚙️ Tasks to Perform

🖥️ Backend (routes.py)

Alright, let's break down the backend tasks step by step. We're going to be tweaking our routes.py file to handle all the necessary logic for our CRUD operations. Here’s what we need to do:

• [ ] GET Handling for /admin/documentacion (gestion_documentacion):
  • First up, we need to handle GET requests to /admin/documentacion. This route, also known as gestion_documentacion, will be responsible for fetching and displaying a list of all documents from the documento table. Think of it as the admin's dashboard for seeing all the available documents at a glance. The goal is to present a clear and organized view of all documents, making it easy to find and manage them. To achieve this, the backend needs to query the documento table, retrieve all the necessary fields (such as title, description, and file path), and then pass this data to the frontend for rendering. Proper error handling should be implemented to gracefully handle cases where the database query fails or no documents are found. Additionally, consider adding pagination to this view if the number of documents is expected to be large, to ensure a smooth and responsive user experience.
• [ ] Creating /admin/documentacion/agregar Route (GET and POST):
  • Next, let's create a route for adding new documents. We'll need to handle both GET and POST requests here. The GET request will serve the form for adding a new document, while the POST request will handle the file upload and database entry. The POST request is where the magic happens. It needs to handle the file upload, save the file to the server (for example, in static/docs/), and then store the file path in the database. This involves several steps, including validating the file type, generating a unique file name to avoid conflicts, and securely storing the file. The database entry should include the file path, title, description, and any other relevant metadata. Proper error handling is crucial here to handle cases such as invalid file types, failed file uploads, or database errors. Consider adding progress indicators during the file upload process to provide feedback to the user and improve the overall user experience. Additionally, ensure that the file storage location is properly configured and secured to prevent unauthorized access.
• [ ] Creating /admin/documentacion/modificar/<int:id> Route (GET and POST):
  • Now, let's tackle the route for modifying existing documents. Similar to adding documents, we'll need to handle both GET and POST requests. The GET request will fetch the document's current data and populate the form for editing, while the POST request will handle the updates. This route, /admin/documentacion/modificar/<int:id>, will allow admins to edit the title and description of a document. The <int:id> part is important – it specifies that we're dealing with a specific document identified by its ID. When a GET request is made to this route, the backend needs to fetch the document's current data from the database based on the provided ID. This data should then be passed to the frontend to populate the form fields for editing. When a POST request is made, the backend needs to update the document's title and description in the database with the new values submitted through the form. Proper validation should be implemented to ensure that the updated values are valid and to prevent any potential security issues. Consider adding a confirmation step to allow the user to review the changes before they are saved. Additionally, ensure that the user has the necessary permissions to modify the document before allowing the update.
• [ ] Creating /admin/documentacion/eliminar/<int:id> Route (POST):
  • Last but not least, we need a route for deleting documents. This route, /admin/documentacion/eliminar/<int:id>, will handle POST requests to delete a document from the database. It should also optionally delete the physical file from the server. When a POST request is made to this route, the backend needs to delete the corresponding record from the database based on the provided ID. Additionally, it should optionally delete the physical file from the server to prevent orphaned files from accumulating. Before deleting the file, ensure that the user has the necessary permissions and that a confirmation step is in place to prevent accidental deletions. Proper error handling should be implemented to handle cases such as database errors or file deletion failures. Consider adding a mechanism to archive deleted documents instead of permanently deleting them, to allow for potential recovery in the future. Additionally, ensure that the file deletion process is secure and prevents unauthorized access to the deleted files.

🎨 Frontend

On the frontend side, we'll be creating two main templates:

• [ ] Creating templates/admin/documentacion.html:
  • This template will display the list of documents. Each document should have **
