<issue_comment>username_6: This should be noted in a changelog somewhere because on upgrade to 4.2 I had some production projects lose tag data because when the resources were saved again the commas were lost and it created new tags.
<issue_comment>username_7: Created a [wiki-page](https://github.com/mbleigh/acts-as-taggable-on/wiki/Add-a-tag-field-to-forms-in-Rails--4.2-and-above), addressing this issue.
<issue_comment>username_8: For `simple_form` it's like this:

`<%= f.input :tag_list, input_html: {value: @something.tag_list.to_s} %>`
<issue_comment>username_9: This was our solution:

```ruby
module ActionView::Helpers::TagHelper
  private
  def tag_option_with_tag_list_support(key, value, escape)
    if value.is_a?(ActsAsTaggableOn::TagList)
      value = escape? safe_join(value, ActsAsTaggableOn.glue) : value.join(ActsAsTaggableOn.glue)
    end

    tag_option_without_tag_list_support key, value, escape
  end
  alias_method_chain :tag_option, :tag_list_support
end
```The Indian Institutes of Management (IIMs) have flagged off the admission season to B-schools by announcing the dates for the Common Admission Test (CAT), which is set to begin on October 27 in 33 cities across the country. Based on last year's feedback, testing agency Prometric has made several changes to ensure smooth conduct of the exams this year. CAT 2009, when the test first went online, was riddled with glitches. This year the testing window has been expanded from 10 days to 20 days. The exam will be spread out between October 27 and November 24 to ensure that too many candidates don't log in at the same time and jam the server.
The implementing agencies, too, have been changed this year. The IIMs have decided to let go of NIIT, which was the implementing agency for CAT 2009, and have instead chosen Everonn Education and Meri-Trac as delivery partners for this year's test. Everonn is an existing test delivery partner of Prometrics IT certification business, and Meritrac, too, has a good track record in conducting examinations in India. They will ensure site-readiness of the test centres, and be in charge of test administration and onsite technical support, said Soumitra Roy, Managing Director of Prometric, India.As he was speaking, Vahn felt conflicted about how things had turned out since it would be very difficult for Revis going forward. He wanted to help her, but one of the things he needed to identify was if the vows that bound her in the past were still in effect. Vahn knew a lot about the different vows, so Enyo wouldn’t have been able to force Revis to take anything binding since people couldn’t be manipulated to make vows against their will. If Revis was being controlled or influenced by the magic core, she would have only been able to make lesser vows. In most cases, it was impossible to use hypnosis or mind-control to force someone to take a vow, as the world itself would oppose and even punish you. Vahn needed to Anubis to inspect her soul to determine what, if any, vows she was still bound to.
Though vows could be very powerful bindings, they didn’t ‘force’ you to act a certain way unless you wanted to avoid the repercussions of the vow. Revis wouldn’t be compelled to do anything and, if she was a strong enough person, the worst case scenario is that she would have to deal with the backlash. She might lose her power, or even obtain a curse, but those were both things Vahn could treat symptomatically. Enyo wouldn’t have been able to force her to take a vow that would result in her death, as those required a person to be sound mind and fully aware of the consequences, without secondary influences and manipulation. If the person wasn’t determined to take the vow on their terms, the world would punish the person trying to force the vow onto them.
Revis ruffled her own hair, clearly annoyed by the situation since it was very frustrating not being able to recall any details. She didn’t even understand why she had any memories at all, or how she was even able to speak since some of the words didn’t even make sense. Part of her knew what they meant but, whenever she tried to focus on any details in specific, it was like her mind was shrouded by a dense fog. She even suspected that Vahn and Asfi were actually trying to manipulate her but it didn’t seem to be the case based on their body language and their words. Though Revis didn’t understand why she knew this, part of her seemed to simply ‘know’ what he was telling her was the truth.
Releasing a sigh, Vahn turned to Asfi and said, “We need to return to Lil Geirr and inform Finn about what has happened. Anything you documented in the scroll in regards to the fortress and its surroundings needs to be made known so modifications can be made. This time around, I trust that you won’t be privy to the exact changes since this fiasco has already caused more trouble the necessary. Make sure those two are aware of the reason why they were attacked in the first place, as they share the blame in this matter…” Vahn released another sigh, because it was partially his fault as well, though the main fault undoubtedly lay with Hermes.
Vahn stared at Revis blankly for a few moments before pulling out an overcoat that she could wear, which was quickly snatched up as Revis rose to her feet, asking, “So, what’ll it be, Doc…? Don’t pick anything too strange though, and make sure to explain the meaning. I don’t want any names I don’t understand…” Though he hadn’t even sweat during their fight earlier, Vahn now felt his palms become a little clammy since he had learned from experience that his naming sense was rather terrible. Being put on the spot like this made him feel strangely nervous, which Revis seemed to find amusing based on the cheeky grin that had appeared on her face.
As if coming up with a simple solution, Revis’ eyes widened slightly as she asked, “How about Rufina Vermillion then? You and Blue both had two names, so I’ll take two as well. Simple, right?” ‘Rufina’ had a vibrant smile on her face, distinctly different from her cold appearance from earlier when she behaved more like a machine than a person. She still had slightly angular eyes, that made her look perpetually annoyed, but that didn’t do much to detract from her smile. Vahn’s eyes widened more than a little while even Asfi released a sigh, muttering something under her breath that only Fenrir likely picked up.
Since she seemed satisfied with it, Vahn nodded his head and said, “Very well, you’ll be Rufina Vermillion from now on. It’s nice to meet you, Rufina…” Vahn noticed that Revis’, now Rufina’s, name had changed in his interface when she accepted the name. Previously, it had been showing as ‘?????’, which was why he hadn’t been referring to her as Revis when speaking. Her Affection itself was now at 54(Curious), with her Intrigue at 28(Cautious), so it was a step in the right direction. As for her aura, it was almost entirely a light purple but there was a small amount of yellow mixed in. Since she had amnesia, it made since she was full of fear and inhibitions but Vahn was expecting she would get better with time.
 Rufina’s eyes widened into saucers as her complexion become somewhat rosy. She brought her gloved hand to her face, awkwardly scratching her cheek as she asked, “So, got any food, Doc? Feels like I haven’t eaten anything in days…” Vahn stared blankly at Rufina for several seconds before bursting into laughter, earning a glare from the mature looking woman who balled her hands into fists and shouted, “Don’t laugh at me you brat!” At the same time as she decided to shout, Rufina’s stomach once again began to ‘growl’ in a very audible manner, causing her to rub her stomach in frustration, cursing under her breath.
Scientists claim they may have identified gut bacteria that could convert blood types A and B into type O.
People with type O-negative blood are known as universal donors, meaning they can give to anyone with any blood type.
This is why people with this blood type are always in high demand in medical emergencies and natural disasters.
But with only 6.6 percent of the US population carrying O-negative blood – and less than 10 percent of all Americans donating – blood banks are often in short supply.
Researchers, from the University in British Columbia in Canada, however, say they’ve discovered an enzyme found in the human gut that could covert other blood types in type O – potentially putting an end to the massive blood shortage
