I have setup a custom embed model so I can add things like instagram or youtube embeds to actiontext content on my site. It's working correctly for instagram embeds, but not youtube.
As a reference, the youtube embed code I want to display is:
<iframe width="560" height="315" src="https://www.youtube.com/embed/F0kgw25zjpc" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
models/recipe.rb:
class Recipe < ApplicationRecord
has_rich_text :body
...
end
models/embed.rb:
class Embed < ApplicationRecord
include ActionText::Attachable
validates :content, presence: true # content is text in db
end
embeds/_embed.html.erb:
<div class="text-center">
<div class="d-inline-block h-100">
<%= embed.content.html_safe %>
</div>
</div>
views/recipes.show.html.erb (where I'm trying to actually display the content - #recipe.body is the actiontext):
<h1><%= #recipe.title %></h1>
<%= #recipe.body %>
I can see the youtube embed when editing the content (it shows in the trix editor), but when viewing the rendered content, nothing - I can see the surrounding divs so I know it's being added to the page, but no iFrame.
It's annoying because an instagram embed works fine - for reference the instagram embed looks something like:
<blockquote class="instagram-media" data-instgrm-captioned data-instgrm-permalink="https://www.instagram.com/p/B_AHNeYgHfr/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="12" style=" background:#FFF;

I have a feeling this is iframe related, as changing embeds/_embed.html.erb to:
<iframe width="560" height="315" src="https://www.youtube.com/embed/F0kgw25zjpc" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
renders nothing at all.
Ok, so I figured this one out. As suspected, it's an iframe (or more specifically a non-whitelisted tag) issue with Rails sanitization, not specifically ActionText rendering.
The solution is to append iframe to whitelisted tags like so:
config/initializers/html_sanitation.rb:
Rails::Html::WhiteListSanitizer.allowed_tags << "iframe"
In config/application.rb, add the following:
class Application < Rails::Application
# ...
config.to_prepare do
ActionText::ContentHelper.allowed_tags << 'iframe'
end
end
So I'm trying to make a website with two different links- however, the CSS that I'm editing them with recognizes them both as "a" and puts them in the same spot. This is aggervating, I've tried basing the css off of the they're in, but that doesn't seem to be working. Here's my code:
<html>
<h1>
<div id = "firstbutton">
GOOGLE
<style type="text/css">
a {
color: rgb(255,255,255);
font-size: 60;
font-family: Arial;
text-decoration: none;
position: fixed;
top: 50%;
left: 50%;
margin-top: -85px;
margin-left: -145px;
}
</style>
</div>
<div id = "forumbutton">
Forum
<style type="text/css">
a{
color: rgb(255,255,255);
font-size: 30;
font-family: Calibri;
position: fixed;
text-decoration: none;
top: 50%;
left: 50%;
margin-top: 260px;
margin-left: -45px;
}
</style>
</div>
</h1>
<body>
<audio src="goingdown.mp3" autoplay></audio>
<style type="text/css">
body {
background-image: url('spacewallpaper.jpg');
}
</style>
</body>
</html>
Set ID for each a element
Then css should look like:
a#name1{ ... }
a#name2{ ... }
This is where classes come in handy. You should add a class attribute to each a and define your CSS with that class. Or you could use an ID.
Styles can get overridden with multiple style blocks or declarations. It doesn't apply the the closest tag.
Here is your fixed code
JS Fiddle - Working
.GClass a {
color: rgb(255,255,255);
font-size: 60;
font-family: Arial;
text-decoration: none;
position: fixed;
top: 50%;
left: 50%;
margin-top: -85px;
margin-left: -145px;
}
.FClass a{
color: rgb(255,255,255);
font-size: 30;
font-family: Calibri;
position: fixed;
text-decoration: none;
top: 50%;
left: 50%;
margin-top: 260px;
margin-left: -45px;
}
<html>
<h1>
<div id = "firstbutton">
GOOGLE
</div>
<div id = "forumbutton">
Forum
</div>
</h1>
<body>
<audio src="goingdown.mp3" autoplay></audio>
<style type="text/css">
body {
background-image: url('spacewallpaper.jpg');
}
</style>
</body>
</html>
You should set and ID for each element you are trying to add (implement), then you can call that element easily inside the CSS.
Also Element div cannot be nested inside element h1!
The font-size should be marked in pixels. Example font-size: 30px;.
The structure of your document is slightly scattered...
it is better to put all your styles in the head section an not scattered through the body section
<html>
<head>
<style type="text/css">
body
{
background-image: url('spacewallpaper.jpg');
}
a
{
color: #FFFFFF;
text-decoration: none;
top: 50%;
left: 50%;
}
.FirstLink
{
font-size: 60;
font-family: Arial;
position: fixed;
margin-top: -85px;
margin-left: -145px;
}
.SecondLink
{
font-size: 30;
font-family: Calibri;
position: fixed;
margin-top: 260px;
margin-left: -45px;
}
</style>
</head>
<body>
<h1>
<div id = "firstbutton">
<a class="FirstLink" href="http://google.com">GOOGLE</a>
</div>
<div id = "forumbutton">
<a class="SecondLink" href="http://www.google.com">Forum</a>
</div>
</h1>
<audio src="goingdown.mp3" autoplay></audio>
</body>
</html>
Try the code above and compare it to your own for reference to see the differences. Good luck.
