Posted in update a model attribute with the ujs ?.

To use ujs to update the result whenever the user selects from the select dropdown, you can follow these steps:

Add a remote: true option to your select form to allow it to submit the result via AJAX:


<%= form_for @game, remote: true do |f| %>
<%= :result_outcome, options_for_select(Game.results.keys, @game.result&.outcome), {}, {class: 'active selected', id: 'game-result'} %>
<% end %>

Add an id attribute to the select dropdown to identify it uniquely:


<%= :result_outcome, options_for_select(Game.results.keys, @game.result&.outcome), {}, {class: 'active selected', id: 'game-result'} %>

Add a data-remote and data-url attribute to the select dropdown to specify the AJAX endpoint:


<%= :result_outcome, options_for_select(Game.results.keys, @game.result&.outcome), {}, {class: 'active selected', id: 'game-result', data: {remote: true, url: game_path(@game)}} %>

Add a respond_to block to your controller's update action to handle the AJAX request:


def update
@game = Game.find(params[:id])
@game.result.update(outcome: params[:game][:result_outcome])

respond_to do |format|
format.html { redirect_to @game }

Add a update.js.erb view file to your views/games directory to handle the AJAX response and update the DOM:


$('#game-result').addClass('active selected');

This should allow you to update the result whenever the user selects from the select dropdown using ujs in Rails.

I'm sorry, but I'm not quite sure what you're referring to. Could you please provide more context or information about the topic you are discussing? That way, I can provide a more accurate and helpful response.

Posted in How can I whitelist an heroku app for external api?

While Heroku does not support assigning a static IP address to an app, there are some workarounds you can consider:

Use a third-party add-on: There are some third-party add-ons like Fixie or QuotaGuard that can provide a static IP address for your Heroku app. These add-ons work by routing traffic through their own proxy servers, which have static IP addresses.

Posted in Where can I get started?


If you're new to programming, I would suggest starting with learning the basics of Ruby before diving into Rails. This will give you a solid foundation to build on and understand the syntax and structure of the language.

Once you feel comfortable with Ruby, you can then move on to learning Rails.

Posted in Native Mobile Options

There are a few steps you can take to turn your Rails app into a native app for iOS and Android:

Build an API: You'll need to build an API that your mobile apps can use to access data from your Rails app. You can use Rails to build a JSON API using something like the jbuilder gem.

Choose a framework: There are several frameworks available for building native apps using web technologies like HTML, CSS, and JavaScript. PhoneGap (now known as Apache Cordova) is still a popular option, but there are other frameworks like React Native and Ionic that you can consider as well.

Build the app: Once you have your API and your framework in place, you can start building your app. You'll need to create screens, handle user input, and make API requests to your Rails app.

Test and deploy: Once you have a working app, you'll need to test it thoroughly and deploy it to the App Store and/or Google Play Store.

As for resources, there are many tutorials and guides available online for building native apps with Rails and various frameworks.

To achieve human-readable URLs for your site's filters, you can use a technique called "slugifying" or "URL-friendly encoding". This involves converting your filter keywords into a string of lowercase letters and hyphens that can be easily read and understood by search engines and users.

There are several gems available that can help you with audio file manipulation and metadata management.

RubyAudio: A gem for working with audio files in Ruby. It provides support for reading and writing common audio file formats, including MP3, and can be used to perform various audio processing tasks.

Posted in What SEO tools do you use as a developer?

Sure, here are some tips to make your project SEO-friendly at launch:

Do Keyword Research: Before starting any project, do keyword research to find the most relevant and high-traffic keywords for your project. Use tools like Google Keyword Planner, SEMrush, or Ahrefs to help you identify the best keywords to target.

Optimize On-Page Elements: Ensure that your website has a clear structure, easy navigation, and optimized meta titles and descriptions, header tags, and image alt tags. Make sure the content on each page is unique and valuable to the user.

Use Clean and Searchable URLs: Use simple and meaningful URLs that are easy to read and search engine friendly. Use hyphens to separate words in your URLs instead of underscores or spaces.

Mobile Responsiveness: Ensure that your website is mobile-responsive and provides a good user experience on all devices. Google now gives preference to mobile-friendly sites, and more people are accessing websites on mobile devices than ever before.

Page Speed Optimization: Optimize your website to load quickly. Use tools like Google PageSpeed Insights to identify areas that need improvement and make necessary changes to improve site speed.

Remember, SEO is an ongoing process, and it takes time to see results. But by following these tips, you can ensure that your project is set up for success from the start.

One library you could consider is Okta's Okta Auth JS library, which supports PKCE and can be used with custom OAuth2 providers like Doorkeeper. Another option is OIDC Client, which also supports PKCE and can be configured to work with custom OAuth2 providers. Both libraries have good documentation and community support, so they may be worth exploring for your use case.

Posted in How I setup sqlite3 on Ruby on windows

It sounds like there might be an issue with your system environment variables or path settings. Here are a few things you can try:

Ensure that you have installed the sqlite3 development package for your system. This package contains the necessary header files and libraries needed to compile the sqlite3 Ruby gem. You can usually install this package using your system's package manager.

Ensure that the path to the sqlite3 executable is included in your system's PATH environment variable. You can check this by running echo $PATH in your terminal. If the path to sqlite3 is not included, you can add it by editing your system's environment variables.

Try installing the sqlite3 gem with the --with-sqlite3-dir flag, specifying the path to your sqlite3 installation. For example:


gem install sqlite3 -- --with-sqlite3-dir=/usr/local/opt/sqlite

Note that the exact path may vary depending on your system.

If you are still having issues, you can try using the sqlite3-ruby gem instead of the sqlite3 gem. This gem is a pure-Ruby implementation of the sqlite3 API, and may be easier to install.

Finally, if you are using WSL, you may need to ensure that the sqlite3 package is installed within your WSL environment, rather than your host Windows environment.

I hope this helps!

Posted in Jumpstart

Jumpstart is a great tool for building web applications and marketplaces. However, whether it is ready for Stripe Connect or not depends on your specific use case and the functionality you need.

Stripe Connect allows you to easily process payments between multiple parties, such as sellers and buyers, and to collect a percentage of each transaction as a platform fee. To use Stripe Connect with Jumpstart, you will need to integrate the Stripe Connect API into your application.

You can start by reading the Stripe Connect documentation and then researching how to integrate it into a Rails application. There are many resources available online, including tutorials and sample code, that can help you get started.

I'm sure a lot of people here have experience with RubyMotion. It's an awesome tool for mobile app development and I highly recommend it.
