Building a Seed.py File and Synchronizing it Models in Python
Tags: python, flask, beginners, tutorial
Published: 2023-06-30 15:25:59

## Understanding the Seed.py file:

The seed.py is the file that runs once in order to populate the database with data. Hand in hand with the built out models.py, it allows the user to automate the process of table creation and because of this, you can ensure that your initial database has a consistency in how it is built out.

## Step by Step on how to Synchronize Data with Models:

1. First things first, make sure you are importing the necessary models. These will be important to access the models.py and will allow you to interact with the database.

2. In the seed.py file, create instances of the models you've defined and imported. These instances represent the data that you want to insert into your database. At this step you can manipulate the data as you please, manipulating key names, values, and so forth.

3. Now that you've created your instances, and you're happy with how they look as well as the information they contain, it's time to insert them into the database. Use the methods provided by your database (likely SQLAlchemy) to insert the data. It is important that you ensure that the attributes of the models are mapped out to the correct fields in your database. 

4. All that's left to do is the big part: execute the seed.py file. You can execute it manually through terminal or sometimes as part of a larger automated process. This will trigger the insertion of pre-made data into the corresponding fields of the database.

If you have done everything correctly, you should see your pristine tables filled with the data that you assigned to them in your seed.py file.

## Tips and Tricks

If it didn't populate as you had hoped, here are a few tips/tricks that I have found useful in my time with building out seed files.

- **Be consistent with naming.** It may sound cliche, but make sure that you are using the same name to refer to the same thing throughout your files. Capitalize what needs to be capitalized, add and 's' to what needs to be plural, and so forth. Pick a name for something and stick it, you'll thank yourself later.

- **Maintenance and Upkeep.** Regularly review and update the seed file as needed. It may seem intimidating, but you can always just follow the instructions above to successfully re-seed your data. You've done the hard part, don't stress if you have to update. 

## Conclusion

Building a seed.py file aligned with your models.py file is crucial for maintaining consistency and efficiency when populating your database with initial or test data. By following the steps outlined above and being mindful of best practices, you can ensure that your seed data accurately reflects the structure of your models. Embrace the power of the seed.py file and enjoy a streamlined approach to managing your database initialization process.

I feel like weekend is the best time to build micro-project


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/mytrhj3osty98ixyshvq.png)


I am building Infinite UI - UI components collection which has a lot of Tailwind style components and on top you can generate your own. 

https://infiniteui.co


This project is a result of my previous project

https://everything.to - where you can generate any type of components. Next/JS+ Tailwind UI 
By the way it gives a lot of errors in generation. 

**Update 1: Saturday 18.00 CEST)**
Here I am trying to turn React component into HTML that it generates better. 

But that is where I am at now -Satarday evening - designing the page for each generated component. 

It does not look good so far hahah 

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/edkpcouijfs3mg5ky2ge.png)

The slug page already created still does not look great.

**Update 2: Sunday 12.00 (CEST)**

Slug page is there. Need to work on generation that from existing component you need to generate new one. 

I have a small collection of nice looking component and will continue fill more, by generating it. 


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/h83ffz12ku0s46ffz65d.png)

Elasticsearch is an open-source search engine that enables fast and efficient searching, indexing, and data analysis.
It is built on the Apache Lucene library and can run analytics on data such as textual, numerical, geospatial, structured, and instructed.

## Benefits of Using Elasticsearch:
Elasticsearch offers high-speed search capabilities, scalability, full-text search, and flexible and powerful querying language.
It is the main component in the Elastic Stack, a set of tools for data ingestion, enrichment, storage, analysis, and visualization.

## How Does Elasticsearch Work?:
Elasticsearch works in a distributed manner, where data is divided into multiple shards and distributed across a cluster of nodes.
It has three types of nodes: data node, master node, and coordinating node, each with a specific role.
Elasticsearch indexing involves defining an index and specifying document structure for the data, and Elasticsearch stores the data from the document in a compressed and immutable form called an inverted index.
When a search request is received, Elasticsearch distributes the query to relevant shards, and coordinating nodes merge all the results from the shards.

## Documents:
Documents are the basic unit of information that can be indexed in Elasticsearch.
Data from various sources can be added to the Elasticsearch document using ingestion tools, and indexing allows Elasticsearch searchable.

## Search:
Elasticsearch provides queries with Query DSL for constructing search queries, and distributed search is performed when a search request is received.
Tools such as Search UI and Search API can be used to execute searches, and results can be optimized with query parsing, execution, relevance scoring, sorting, and pagination.

## Conclusion:
Elasticsearch is a powerful tool that can help in efficient and fast searching across large data.
It provides a powerful, distributed search and analytical solution, and using Elasticsearch in Elastic Stack can provide you with benefits such as data visualization with Kibaan and data ingestion and processing with Logstash.

Decoding DeFi: A Friendly Stroll through Blockchain's Newest Neighborhood
Tags: defi, blockchain, web3
Published: 2023-06-30 14:43:37

Hello folks! Today, we're diving into a thrilling and booming area of blockchain technology: decentralized finance, also known as DeFi. But don't worry, we'll keep things super friendly and jargon-free! So, whether you're a tech whizz or just stepping into the crypto-sphere, I promise there's something for everyone here.

## What is DeFi Anyway?
Imagine this: you're in a virtual town, and instead of a traditional bank in the center, there's a community chest that everyone uses. People can lend or borrow from it, earn interest, and even trade with each other, all without the need for a bank manager or complex paperwork. This is a simple picture of what DeFi is all about.

In other words, DeFi is like playing a game of Monopoly where everyone has equal access to the bank's functions. Isn't that fun?

## So, How Does DeFi Work?
DeFi works on the blockchain, a magical sort of digital ledger that everyone can see and that no one person controls. It's like a huge, shared Google Sheet, but way more secure. Every transaction is recorded on the blockchain, making it super transparent and tough to tamper with.

DeFi uses smart contracts, which are like tiny robots living in the blockchain. These smart contracts are programmed to handle financial transactions. They act like the rulebook in our Monopoly game, automatically making sure everything runs smoothly and fairly.

## Why is DeFi Gaining Popularity?
Accessibility: DeFi opens up financial services to anyone with an internet connection. No matter who you are, where you're from, or how much money you have, you can take part.

Transparency: With DeFi, everything is out in the open. You can see exactly what's happening with your money at all times.

Control: You have full control over your money in DeFi. No more middlemen telling you what you can and can't do with your hard-earned cash.

Earn potential: DeFi lets you earn interest on your crypto coins, sometimes at rates much higher than traditional banks can offer.

## DeFi: Not Just a Trend, But a Revolution
Just like the internet changed the way we communicate, DeFi is transforming how we handle money. While it's still young and has a few wrinkles to iron out (like dealing with scams and improving user friendliness), the future of DeFi looks bright and exciting.

So there we have it, a friendly introduction to DeFi in the blockchain world. As always, remember to do your own research and only invest what you can afford to lose. Blockchain is a bustling, fast-moving city, but with a bit of patience and caution, anyone can find their place in it.

Happy exploring, friends! Until next time, stay curious and keep learning!

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/uejj4khbhs1k7ijclh6r.jpg)

Discover how to classify audio chords with our latest YouTube tutorial!
In our latest video tutorial, we will show you how to use a convolutional neural network (CNN) to classify audio chords. 🎧🌈 
We will start by examining a few audio files and playing them back. Then, we will code a transform process to convert the audio files to spectrogram images. Spectrogram images are visual representations of sound waves. They can be used to identify different frequencies and amplitudes, which can be used to classify chords.
Next, we will write a CNN model to generate a binary classification between major and minor chords. We will train the model on a dataset of spectrogram images that have been labeled with the correct chord. The model will learn to identify the features of each chord and to classify them accordingly.
Finally, we will test the model on a new set of spectrogram images that have not been labeled. The model will predict the chord for each image and you can compare its predictions to the ground truth labels.
This video is for anyone who is interested in learning how to use deep learning to classify audio chords. It is also a good resource for music producers who want to use machine learning to improve their music.
I hope you enjoy the video!

What is the difference between a JAR and a WAR file?
Tags: webdev, java, springboot
Published: 2023-06-30 14:35:17

JAR and WAR are two different file formats used in Java Spring Boot for packaging and deploying applications.

The main difference between the two is their purpose and the way they function.

A JAR (Java ARchive) file is a package file format used to distribute Java class files, associated metadata, and resources. It is commonly used to distribute standalone Java applications or libraries.

In general, JAR files are preferable for deploying Spring Boot applications because they are lightweight and can be run as standalone applications without requiring an application server. However, if you want multiple applications running under the same application server, you should choose WAR.

A WAR (Web ARchive) file, on the other hand, is a specific type of JAR file used to package and distribute web applications. It contains the web application’s resources, such as servlets, JSPs, and HTML files, as well as a WEB-INF directory that contains additional metadata, such as the web.xml deployment descriptor.

In summary, the main difference between a JAR and a WAR file is their intended use: JAR files are used for packaging and distributing standalone Java applications or libraries, while WAR files are used for packaging and distributing web applications.

I hope this helps you understand the differences between JAR and WAR in deploy in Java Spring Boot!
The (dis)advantages of programming with chatGPT
Tags: chatgpt, development, programming, ai
Published: 2023-06-30 14:31:26

ChatGPT is an innovative tool that allows programmers to write code faster and easier. With ChatGPT you can simply give a natural language input and the system will automatically generate the appropriate code in the desired programming language. This saves time and effort that would otherwise be spent learning or looking up syntax, functions, or libraries.

However, ChatGPT also has some disadvantages to be aware of. For one, ChatGPT is not always reliable or accurate as it is an artificial intelligence trained on data that may contain errors or gaps. Second, ChatGPT cannot solve all kinds of problems or meet all needs that a programmer might have. Sometimes you still need to adjust, add to, or check the generated code to make sure it serves the intended purpose.

ChatGPT is therefore a useful tool, but not a substitute for your own thinking and learning. It can increase programmers' productivity and creativity, but it cannot replace them.

But it is also suitable for writing texts. Here he is even better than in programming!
