When to use `link_to` and `button_to` in Rails
Tags: rails, ruby, webdev

This article was originally published on [Rails Designer](http://railsdesigner.com/link-button-to/)

---

This article about [forms inside forms](https://railsdesigner.com/forms-inside-forms/) triggered a question from a reader: **when to use link_to and button_to in Rails**? So I wanted to publish this short and quick article.

Rails has had both helpers from the very early beginnings. `link_to` likely from the first release, and `button_to` not much later.

With the release of Rails' ujs, `link_to` could now accept data-attributes as seen in [these older docs](https://guides.rubyonrails.org/v5.0/working_with_javascript_in_rails.html#link-to). This made many Rails developers belief this the right way to do it, but: you should use `link_to` for simple navigation and `GET` requests, and `button_to` for actions that submit data or require additional security, such as `POST`, `PUT,` or `DELETE` requests.

I've seen some nasty HTML-element abuse in pure JavaScript apps too. Something like this:

```js
<div onClick="doClick()">Click me</div>
```

(that's like using a spoon to cut your steak—technically possible, but awkwardly ineffective and a nightmare for accessibility!)

- `link_to` generates an anchor tag (`<a>`): `link_to "Profile", profile_path(@user), class: "link"`;
- `button_to` generates a form with a single button: `button_to "Delete Account", account_path(@user), method: :delete, form: { data: { turbo_confirm: "Are you sure?" } }`.

`button_to` should also, for better accessibility and semantic correctness, be used to open [modal](https://railsdesigner.com/components/modals/) or [slide-overs](https://railsdesigner.com/components/slide-overs/). I could present a counterpoint if the modal or slide-over could also be opened as a separate page.

Also when you replace an element with say, an inline-form, a `button_to` is the correct choice.

It's as simple as that really. Is it `GET` request and does it change the URL? Go for a `link_to`. Otherwise choose `button_to`.

How I Built an AI-Powered YouTube Video Summarizer to Save Time
Tags: ai, productivity, javascript, webdev
Published: 2024-07-01 08:46:21

I wanted to share a project I recently completed that has significantly improved how I consume YouTube content. As someone who loves learning from YouTube but found myself spending too much time watching videos at accelerated speeds and skipping chapters, I decided to build a solution: TLDW (Too Long; Didn't Watch).

**Why I Built TLDW**
I was overwhelmed by the number of YouTube videos I wanted to watch but didn't have the time for. Watching videos at 2x speed and constantly skipping ahead wasn't efficient or enjoyable. I realized I needed a tool to summarize videos quickly, so I could get the essential points without watching the entire content.

**What is TLDW?**
TLDW is a Chrome extension that uses AI to summarize YouTube videos into concise bullet points. Here's how it works and what it offers:

- AI-Powered Summaries: TLDW uses LLAMA3 to generate accurate and coherent summaries of YouTube videos.
- Interactive AI: You can ask the AI for detailed explanations on specific points, ensuring you get all the necessary information.
- Free and Premium Plans: Enjoy up to 5 video summaries per day for free, or unlock unlimited access for just €1.90/month.
- Privacy Focused: No personal data is collected.
- Secure Payments: All transactions are processed securely via Stripe.

**How I Built It**
TLDW was developed using JavaScript, integrating with the LLAMA3 AI model to generate summaries. The extension extracts text from the video's transcription, which is then used to contextualize the AI's summary.

**Challenges and Learnings**
Building TLDW wasn't without its challenges. Here are a few key takeaways from the development process:

- Handling Video Transcriptions: Extracting and processing text from video transcriptions required precise handling to ensure accuracy.
- AI Integration: Integrating LLAMA3 for real-time summarization demanded significant fine-tuning to get the summaries just right.
- User Experience: Ensuring the extension was user-friendly and provided real value was crucial. Iterative feedback and testing helped refine the product.

**Try TLDW**
If you're like me and need to save time while staying informed through YouTube, give TLDW a try. You can find the extension on the Chrome Web Store.

Published: 2024-07-01 08:27:07

**Problem description & analysis**:

Below is an irregularly categorized detail table. Column A and column B are categories and both have duplicate values. Column C contains detailed data consisting of strings separated by "comma+space", and there are duplicates among the string values.

![original table](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/py30ju8xfz6hla19ouu2.png)

Task: Split detail data in each category, group them by category, get unique values of each group, and concatenate them using "comma+space".

![desired table](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/t9wl7uecr9htblcmxsh6.png)

**Solution**:

Use _**SPL XLL**_ to enter the following formula:

```
=spl("=E@b(?.group(~1,~2;~.conj(~3.split@ct()).id().concat("","")))",A2:C12)
```
As shown in the picture below:

![result table with code entered](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/v1ytkjnj8xbuu49vyi61.png)

**Explanation**:

group()function groups rows and handles data in each group; ~1 represents the first sub-member of the current member; split@ct splits each string by comma and performs trim operation to remove spaces at both sides; id() removes duplicate members. E@b converts the Excel table to a sequence without titles.
