Yeah, you'll want to sanitize it. I can't cover everything in the series, so that's one you'll have to add in. Good catch, it'll be useful for anyone else following this to be aware of that.

More stuff coming soon! :D

The simple solution for most of Bootstrap is just to use the turbolinks:load event for re-initializing your JS. For example, to enable tooltips and popovers for all pages, you can do:

$(document).on 'turbolinks:load', ->
  $('[data-toggle="tooltip"]').tooltip()
  $('[data-toggle="popover"]').popover()

Some of the other things like bootstrap modals don't need this because the JS is written in a way that makes it automatically compatible from what I've seen. Bootstrap 3 doesn't have too many compatibility issues with Turbolinks 5 these days.

Yo Szilard! It's been a while since I've setup Cloudfront especially with fonts.

Did you make any progress on this?

It's not quite right. You do lose some of the benefits of sass if you use requires because you can't share sass variables or mixins between files with requires like I talked about in the episode.

The thing they don't talk about is the compile times are incredibly slow when you don't split up your code in requires. When your sass code is modular, you can absolutely split it up and use requires for compile performance in development.

Hey Emil,

For the most part, you can just plug in Shrine by opening up a File object in Ruby and then assigning it to the shrine attribute and calling save. That's basically the same process that Shrine uses on a browser upload so there is little to no difference to do this from an already downloaded file.

download = File.open("PATHTOFILE", "rb")
@record = Record.where(youtube_id: ID).first_or_create
@record.video = download
@record.save

You might need to delete the file you downloaded once this is complete so you don't have duplicate files on disk.

These are likely the two main ones that could be misconfigured:

1. Make sure elasticsearch is bound to the public IP address and not just running internally.
2. Check to make sure the port is open on it through the firewall.

It's probably one of these two but could be something else. It's been a while since I setup ES across machines.

That's relatively easy. You can just save a record for every attempt and create/update those according to the number of attempts and they display them on that page. Just need to record the results of the background job after it succeeds or fails and that should be it!

So Heroku won't actually allow you to store files permanently on their servers. You are required to use an external storage service like S3.

If you deployed to Digital Ocean, you can store files since you control the server. Migration isn't the worst, but it can take some time. If you plan on people uploading a lot of files, it's probably worth just using S3 from the beginning.

In either case, I guess I would say you might as well just use S3 from storage from the beginning if you plan to using S3 later.

Hey Nino!

I'm not quite sure what's happening. You'll have to define what "When I try to change the provider on a test account the change fails." means. What isn't working?

Also remember that all these users won't have put in a password, so you'll have to get all of the LinkedIn users to do the forgot your password process in order to setup passwords for them for the first time.

Hey Stan! Like an XML feed of them? If so, it's relatively easy. You've just got to create an index.xml.builder view which will let you render XML.

You can access all the instance variables you need from the controller just like a normal view so you can loop through the posts and print them out in the XML. I believe you'll want the tags and structure mentioned in the following example to conform to what the feeds need for tags.

Basecamp uses this for their feed, for example:

xml.rss("version" => "2.0", "xmlns:dc" => "http://purl.org/dc/elements/1.1/") do
  xml.channel do
    xml.title(@feed_title)
    xml.link(@url)
    xml.description "Basecamp: Recent items"
    xml.language "en-us"
    xml.ttl "40"

    @recent_items.each do |item|
      xml.item do
        xml.title(item_title(item))
        xml.description(item_description(item)) if item_description(item)
        xml.pubDate(item_pubDate(item))
        xml.guid(@person.firm.account.url + @recent_items.url(item))
        xml.link(@person.firm.account.url + @recent_items.url(item))

        xml.tag!("dc:creator", item.author_name) if item_has_creator?(item)
      end
    end
  end
end

Btw, definitely doing a screencast on this soon.

The cool part about webhooks is that they're just HTTP requests. All you have to do is collect a URL from your user, and then make a POST request to it with some data. I would recommend using rest-client for making the POST and sending it from a background job so that you can retry it if it fails. That's really all their is to it.

You ideally want to schedule your retries for extended periods of time, so if the first one fails, retry in a minute, retry in 5 minutes, retry in 10 minutes, 30 minutes, or something like that where there is some backoff. And then after X number of tries you can give up.

I'd toss a byebug in there and inspect each line to see what's causing it. Make sure a_categories is just an array of one item, then make sure categories is just an array of one Style, and so on.

Also keep in mind that you changed to operate on the Join table where I was showing querying the Category table instead. The reason for that was the query can verify those Category records exist.

Your code works differently than my example and needs to change a little if you do want to skip the verification that the Categories exist like mine did.

It's okay to do that, but instead of doing a where query, you would want to just do something like this:

a_categories.each do |category_id|
  post.styles.where(category_id: category_id).first_or_create
end

Note that this does not verify if a category ID is correct. If you put in say, category ID of 99999 and there was no Category record with that ID, you'll be inserting invalid data into the db. This might be fine, or it may be something you don't want, so I'd be careful with that.

Another thing to double check with this is to make sure that it's idemopotent, meaning if you import the same csv twice, it doesn't create duplicate categories per post. I'm not sure if assigning the categories like that will or not, but it's worth checking.

Oh derp. I wasn't paying attention whatsoever. :) My bad!

So if you've got the array of 1, 2, 3 and these match the ID column for your Category records, you can say

category_ids = ids # if this is a comma separated string of ids, you'll need to split(",") it into an array instead
categories = Category.where(id: category_ids)
post.categories = categories

This will automatically create the join records in the Styles table between the two and do it all in one batch because you'd be querying for the entire array of categories and then you can assign them using the association.

Of course, this assumes the categories are already in the database as a caveat.

Yessir! I'm still working on it. Had a couple things come up and had to postpone the episode a little bit. Working on the screencast this afternoon. :)

Sup Ryan! 👍 for formatting the markdown perfectly.

First off you'll need a join table to connect the two models. PostCategory can belongs_to :post and belongs_to :category and give you the ability for your post to has_many :categories, through: :post_categories. That will give you the ability to associate multiple categories to a post and reuse the categories on multiple posts.

The next question, of course, is how does your CSV format the categories in it? You'll basically just want to split those up, and then do a Category.find() on them to grab the categories and you can say something like post.categories << Category.find_by(name: category_name)

What's up Ryan! 😎 Just wanted to say hi! Awesome to have you, and your projects look awesome!

@Nick stop it you. 😊

We gotta come together and make sure to crack the whip on Andrew so he doesn't die during his first half-marathon.
