Frequently Asked Questions

What types of businesses or applications would benefit most from using this Flask web app template with authentication?

This Flask web app template with authentication is ideal for a variety of businesses and applications, particularly those developing SaaS (Software as a Service) products. It's well-suited for: - Startups building user-centric web applications - Freelancers or agencies creating client portals - E-learning platforms requiring user accounts - Personal finance or budgeting tools - Health and fitness tracking apps

The template provides a solid foundation for any application where users need to manage their own data securely, making it a versatile starting point for many web-based services.

How does this template differ from an internal tool skeleton, and why might a business choose this one instead?

This Flask web app template differs from an internal tool skeleton in that it doesn't include team features. Instead, it's designed for applications where multiple users manage their own individual data. A business might choose this template over an internal tool skeleton when: - Developing a product for a broad user base rather than for internal team use - Creating a service where user privacy and data separation are crucial - Building a scalable SaaS application that needs to handle many independent user accounts - Focusing on individual user experiences rather than collaborative features

For example, if you're building a personal journal app or a individual task management tool, this template would be more appropriate than an internal tool skeleton.

What are the potential time and cost savings of using this Flask web app template for a startup?

Using this Flask web app template can provide significant time and cost savings for a startup: - Reduced development time: The authentication system is already set up, saving potentially weeks of work. - Lower initial costs: By starting with a pre-built structure, startups can allocate more budget to unique features. - Faster time-to-market: With core functionalities in place, products can launch sooner. - Reduced security risks: The template includes basic security measures, minimizing the risk of early vulnerabilities. - Scalability: The structure supports growth, preventing costly rewrites as the user base expands.

These factors can help startups conserve resources and focus on developing their core business logic and unique value propositions.

How can I customize the user model in this Flask web app template to include additional fields?

To customize the user model in this Flask web app template, you'll need to modify the User class in the models.py file. Here's an example of how you might add additional fields:

```python from flask_sqlalchemy import SQLAlchemy

db = SQLAlchemy()

class User(db.Model): id = db.Column(db.Integer, primary_key=True) email = db.Column(db.String(150), unique=True, nullable=False) profile_picture = db.Column(db.String(255)) # New fields first_name = db.Column(db.String(50)) last_name = db.Column(db.String(50)) date_of_birth = db.Column(db.Date) subscription_tier = db.Column(db.String(20)) ```

After modifying the model, you'll need to create and apply a new migration to update the database schema. Remember to update any related functions in database_operations.py to handle these new fields.

How can I add a new route and template to this Flask web app?

Created: | Last Updated:

A ready-to-use template for websites with essential login, registration, and Google sign-in features.

Here's a step-by-step guide on how to use the Login and Registration template:

Introduction

This template provides a solid foundation for building a web application with user authentication functionality. It includes features for user login, registration, and profile management using Flask, SQLAlchemy, and Google authentication.

Getting Started

  1. Click "Start with this Template" to begin using this template in the Lazy Builder interface.

  2. Press the "Test" button to initiate the deployment process. This will launch the Lazy CLI and start the application.

  3. Once the deployment is complete, you'll receive a dedicated server link to access your application.

Using the App

After deployment, you can access your application through the provided server link. The app includes the following features:

  • User authentication with Google
  • User profile management
  • Secure session handling
  • Responsive design for both desktop and mobile devices

Home Page

The home page (/) displays a welcome message with the user's name or email address if they're logged in. If not logged in, users will be redirected to the Google authentication page.

Logout

Users can log out by clicking the "Logout" button in the navigation bar, which will clear their session and redirect them to the home page.

Customizing the App

You can customize various aspects of the application:

  1. App Title: Change the app_title parameter in the flask_app_authenticator function call in main.py:

python app.before_request(flask_app_authenticator( allowed_domains=None, allowed_users=None, logo_path=None, app_title="Your Custom App Title", custom_styles=None, session_expiry=None ))

  1. Logo: Update the logo_path parameter in the same function call to use a custom logo.

  2. Styling: Modify the styles.css file to change the app's appearance. The template uses Tailwind CSS for styling.

  3. Database Schema: If you need to modify the user table or add new tables, update the models.py file and create new migration files in the migrations folder.

Integrating the App

This template provides a standalone web application with user authentication. To integrate it with other services or expand its functionality, you can:

  1. Add new routes in the routes.py file to create additional pages or API endpoints.

  2. Extend the User model in models.py to include more user-related data.

  3. Implement additional database operations in database_operations.py to interact with your data.

  4. Create new HTML templates in the templates folder for new pages or features.

Remember that this template handles user authentication and basic user management out of the box, allowing you to focus on building your application's unique features on top of this foundation.



Template Benefits

  1. Rapid SaaS Application Development: This template provides a solid foundation for quickly building Software-as-a-Service (SaaS) applications, allowing businesses to launch new products or services faster and with less initial development overhead.

  2. Secure User Authentication: The built-in authentication system ensures that user data is protected, which is crucial for maintaining customer trust and complying with data protection regulations in various industries.

  3. Scalable Database Architecture: With SQLAlchemy integration and migration support, the template offers a scalable database structure that can grow with the business, accommodating increasing user numbers and data complexity over time.

  4. Responsive Design Ready: The inclusion of Tailwind CSS and responsive design elements means that applications built on this template will work well on both desktop and mobile devices, catering to a wider user base and improving user experience.

  5. Easy Customization and Expansion: The modular structure of the template, with separate files for routes, models, and database operations, makes it easy for developers to customize the application and add new features as business needs evolve, reducing long-term development costs.

Open Source LLM based Web Chat Interface

This app will be a web interface that allows the user to send prompts to open source LLMs. It requires to enter the openrouter API key for it to work. This api key is free to get on openrouter.ai and there are a bunch of free opensource models on openrouter.ai so you can make a free chatbot. The user will be able to choose from a list of models and have a conversation with the chosen model. The conversation history will be displayed in chronological order, with the oldest message on top and the newest message below. The app will indicate who said each message in the conversation. The app will show a loader and block the send button while waiting for the model's response. The chat bar will be displayed as a sticky bar at the bottom of the page, with 10 pixels of padding below it. The input field will be 3 times wider than the default size, but it will not exceed the width of the page. The send button will be on the right side of the input field and will always fit on the page. The user will be able to press enter to send the message in addition to pressing the send button. The send button will have padding on the right side to match the left side. The message will be cleared from the input bar after pressing send. The last message will now be displayed above the sticky input block, and the conversation div will have a height of 80% to leave space for the model selection and input fields. There will be some space between the messages, and the user messages will be colored in green while the model messages will be colored in grey. The input will be blocked when waiting for the model's response, and a spinner will be displayed on the send button during this time.

FastAPI endpoint for Text Classification using OpenAI GPT 4

This API will classify incoming text items into categories using the Open AI's GPT 4 model. If the model is unsure about the category of a text item, it will respond with an empty string. The categories are parameters that the API endpoint accepts. The GPT 4 model will classify the items on its own with a prompt like this: "Classify the following item {item} into one of these categories {categories}". There is no maximum number of categories a text item can belong to in the multiple categories classification. The API will use the llm_prompt ability to ask the LLM to classify the item and respond with the category. The API will take the LLM's response as is and will not handle situations where the model identifies multiple categories for a text item in the single category classification. If the model is unsure about the category of a text item in the multiple categories classification, it will respond with an empty string for that item. The API will use Python's concurrent.futures module to parallelize the classification of text items. The API will handle timeouts and exceptions by leaving the items unclassified. The API will parse the LLM's response for the multiple categories classification and match it to the list of categories provided in the API parameters. The API will convert the LLM's response and the categories to lowercase before matching them. The API will split the LLM's response on both ':' and ',' to remove the "Category" word from the response. The temperature of the GPT model is set to a minimal value to make the output more deterministic. The API will return all matching categories for a text item in the multiple categories classification. The API will strip any leading or trailing whitespace from the categories in the LLM's response before matching them to the list of categories provided in the API parameters. The API will accept lists as answers from the LLM. If the LLM responds with a string that's formatted like a list, the API will parse it and match it to the list of categories provided in the API parameters.
