Rails backtrace: TypeError in Posts#show

[tripleee]

https://metasmoke.erwaysoftware.com/post/515 gives me a backtrace:

Showing /var/railsapps/metasmoke/releases/20171102150746/app/views/posts/show.html.erb where line #90 raised:

can't convert nil into an exact number

Extracted source (around line #90):

<% end %>

<% if user_signed_in? && current_user.api_token.present? && !@post.is_fp && !@post.is_deleted? && Time.now - @post.created_at <= 1.hour %>
 <p>

Spot checks and a bit of bisection suggests all the oldest posts up through 660 have this.

[j-f1]

Additionally, fetching it from the API fails with undefined method site_domain' for nil:NilClass`:

  def fetch_revision_count(post = nil)
    post ||= self
    # ⬇️ this line here
    params = "key=#{AppConfig['stack_exchange']['key']}&site=#{post.site.site_domain}&filter=!mggE4ZSiE7"

    url = "https://api.stackexchange.com/2.2/posts/#{post.stack_id}/revisions?#{params}"
    revision_list = JSON.parse(Net::HTTP.get_response(URI.parse(url)).body)['items']

We don't have the information we need to find out which sites these old posts were from; unless anyone can think of some way to do that, I'm gonna close this.

Reopening - we can't see what site it's from, but the display page should probably handle that case properly. Unless we want to call it wontfix on the display side, which... I wouldn't be opposed to.

That we can do :)
