You should loop through @user.user_items.includes(:item) instead so you can access the quantity without an extra query. The includes will load the items records efficiently so you aren't doing any N+1 queries.

has_and_belongs_to_many does not allow you to access the join table, and therefore it's very rarely used.

Instead, you just want to define a has_many :through association.

class User
  has_many :user_items
  has_many :items, through: :user_items
end

class UserItem
  belongs_to :user
  belongs_to :item
end

class Item
  has_many :user_items
  has_many :users, through: :user_items
end

This way you can interact with the join table and add things like quantity.

Turbolinks is getting a major update now that HEY.com was released and I believe is going to fix this. One of their main improvements was to fix the forms.

There are easily like 100+ OAuth providers so we just have a few of the most popular ones built-in and made it easy for you to add any of the other available ones.

Hah, you beat me to answering it. I was going to say, we made it so that by default any omniauth libraries you add will be automatically handled by the callbacks controller so there's nothing to do unless you want to extend the integration.

Great! Congrats on your first gem. 🎉

There's nothing special you need to do for deploying Webpacker with Capistrano as it's built-in to the Rails assets:precompile step. The only thing you need to do is make sure that NodeJS is installed and in your PATH when deploying.

You don't want to install NVM as the root user. It should be on the deploy user, same as rbenv. Your code always runs and deploys under the deploy user so you want to avoid root.

I wouldn't override it, just add your new method and call it like safe_link_to.

Roughly something like this:

def safe_link_to(name = nil, options = nil, html_options = nil, &block)
  link_to(name, options, html_options, &block)
end

Then you can add your call to sanitize in there. I think you'd probably wrap options with the sanitize call most likely.

Hey Dainius,

That looks like it would work fine to me. What's happening? You're still logged in after it redirects you?

You're going to want to change that to a DELETE request though, otherwise people can do semi-malicious things and log you out from any website just by making your browser load that URL.

Jesus, yup all the concepts are still the same for Rails 6.

The only change is that Javascript is now primarily written in the app/javascript folder using Webpacker instead of the asset pipeline in app/assets/javascripts. Still works about the same, but has a lot of new features.

Stylesheets still go in app/assets/stylesheets, same as before.

Filled this out a while back. Thanks for putting this together. Always love seeing the results here. 👍

This is awesome Martin!

Rails calls them "routes", not links. That's what you'll want to search for and read up on. 👍

I like that idea. Honestly for most wizard things, I have used Wicked (https://github.com/zombocom/wicked) just about every time. It controls the steps for you and stores them on the model so it remembers the location and everything.

I'd probably still recommend Wicked, but it'd be great to do a basic walkthrough of how you'd implement this from scratch too.

I would pass in the search params into the employee show URL so you can have a link back to the search results that includes the same params.

Ah sorry I was confused. I was thinking of the "active" state of a link / tab / etc.

He's referring to active like the &:active { css selector.

You either need to define it or just have it add the classes you want to the list. "Active" means very different things depending on your UI design.

I either do it inline or in a helper.

Here's an inline example:

<%= link_to "Account", account_path, class: ["blue", ("active" if request.path == account_path)]

Hey Fahad,

Try using this gem to add ActiveStorage support instead: https://github.com/Dreamersoul/administrate-field-active_storage

Yeah, you want to pass it in as a local variable like so:

<%= render 'gyms/card', locals: { gym: gym, index: index } %>

Partials need locals passed in so it can assign those variables and use them the same way as the parent template was.
