Appending to a post's tags in tests

[hasandiwan]

I'm attempting to add openpgp-signed StatusUpdates to diaspora, if there's a 'signed' tag:

`

if @s.tag_list.member?('signed') then
pgp_sign @s
end
@s.save!
`

It's quite straightforward to code, but I'd now like to verify this functionality works. What I have so far is:

`

@s.tag_list = ActsAsTaggableOn::TagList.new(:signed)
@s.tag_list
@s.tag_list
=> ["signed"]
@s.save!
@s.reload
@s.tag_list
=> []
`

Huh?

The forum might be a little bit better avenue for such talk than the issue tracker :)

StatusMessage includes Diaspora::Taggable

diaspora/app/models/status_message.rb

Line 8 in 37a7c0b

include Diaspora::Taggable

Which defines a before validation hook

diaspora/lib/diaspora/taggable.rb

Line 25 in 37a7c0b

before_validation :build_tags # build tags before validation fixs the too long tag name issue #5737

that sets the tag list from what's parsed from the message body

diaspora/lib/diaspora/taggable.rb

Lines 36 to 45 in 37a7c0b

	def build_tags
	self.tag_list = tag_strings
	end
	def tag_strings
	MessageRenderer::Processor.normalize(send(self.class.field_with_tags) || "")
	.scan(/(?:^|\s)#([#{ActsAsTaggableOn::Tag.tag_text_regexp}]+|<3)/u)
	.map(&:first)
	.uniq(&:downcase)
	end

In other words a message's tags are not meant to be a generic metadata attachment system, they're purely there to support the hashtagging feature.
