Few months ago I’ve got an idea of making “Bot Sales Manager” for any online store. Yes, the idea is not unique, “Simpsons Already Did It”, but I havent found any service in the internets which solves this in convenient way.
Big players like eBay and Shopify already created bot solutions for their platforms and now it’s the turn of the rest of e-commerce to have this additional distribution channel.

Hello Elixir fellows!
Released yesterday first version of the ueberauth_line package for oauth authetication for your elixir project.
Installation and using is pretty straightforward, you can use any of other Ueberauth tutorials, like Ueberauth for Facebook.
Tricky thing in using LINE OAuth is setting up LINE Channel and handling errors because they are now really readable (they put error codes in the URL, so keep an eye on your browser address bar).
Be sure you went every step described here in the LINE web login settings very carefully.
Please note that LINE doesn’t provide user email address so we need to mimic it with the LINE user ID and if you need an email for user you’ll need to implement additional step of adding an email.
Hi there,
This is very easy:
1. Create a function in LayoutView `web/views/layout_view.ex`:
def ogtags(assigns) do
if assigns[:ogtags] do
for {key, value} <- assigns[:ogtags] do
raw("\t\n")
end
else
raw("\t\n")
end
end
Here I was using `content_tag` function but it created closed `</meta>` tag which I don’t really like.
In the else clause you can put some default OG tags, I put only `fb:app_id` fir the start.
2. Add this function to the app layout template `web/templates/layout/app.html.eex`:
<%= ogtags(assigns) %>
Where `assigns` is the map which contains almost everything you need to render the view.
3. Update your controller function with OG tags tuple and pass it to template like this:
def show(conn, %{"token" => token}) do
dream = Repo.get_by!(Dream, token: token)
dream = Repo.preload dream, :user
ogtags = %{
"fb:app_id": "430839153628230",
"og:type": "article",
"og:site_name": "InstaDreams",
"og:title": dream.title,
"og:description": dream.body || dream.title,
"og:audio": InstadreamsPhoenix.Router.Helpers.url(conn) <> "/uploads/dreams/#{dream.user.user_id}/#{dream.audio_filename}.mp3",
}
render(conn, "show.html", dream: dream, ogtags: ogtags)
end
I guess the code here is self-explanatory (I used code from my pet-project www.instadreams.com).
If you have some thought how we can improve the code above feel free to post a comment here 🙂
