Yes, it was a fatal flaw in my naming convention that led to the 
confusion. Thank you.

Just to point out that the fundamental mistake you made here was
calling it @following_activities.  If you had called it
@following_posts or something similar then you would probably fnot
have made the error.
For the future simple debugging can be achieved by inserting logger
output in the code at appropriate points, so for example if after the
line
<% @following_activities.each do |user| %>
you insert the line
logger.info "user = #{user.inspect}"
then the debug would be inserted into log/development.log which would
probably have enabled you to see the problem.

In the code you posted earlier the activities are Post objects not
User objects.  Possibly you want
@following_activities.each do |post|

Re: [Rails] How to match a literal colon in a route

[Matt Jones]

I did some digging on this, and I couldn't find a way to make this work 
with a literal in the route itself. 

Splatting works, though:

  get 'baz/*ark_tag/:id/bar' => 'welcome#index', constraints: { ark_tag: 
'ark:' }, as: :ark

will only match paths like "/baz/ark:/123/bar".

It's a little fussy with URL helpers, as you need to always specify ark_tag 
or you'll get an error:

  ark_path(ark_tag: 'ark:', id: 1234)

You'll probably want to define your own helpers that hide that.

The other, bigger issue is the OTHER features of the ARK spec that are 
going to confuse & annoy the default URL parser. In particular:

* the dot-separated components of VariantPath elements. The default Rails 
behavior appends a `.:format` optional parameter to the route. This 
*doesn't* allow further dots.

* the `?` and `??` suffixes. The single question-mark, in particular, is 
only detectable if you check the original request URI in the Rack request. 
I'm also unsure how to talk the regular path helpers into producing a 
single-question-mark URL.

If you're building an application which relies on complex routing of ARK 
URLs, you may want to consider writing your own Rack middleware to hijack 
the URL parsing process and transmute them into something more palatable to 
the existing router.

[Rails] Re: How do I add my own posts plus following users post with Acts_As_Follower Rails 4

[David Williams]

Iterating over the @following_activities instance variable is giving me 
errors for user.avatar.url and user.post. I don't understand why it's 
not collecting all of the information from the user object.

<% if @following_activities.any? %>
  <% @following_activities.each do |user| %>
  <%= link_to(image_tag(user.avatar.url(:thumb), style: 
'text-decoration: none;', class: 'round-image-50-trendy-warrior'), 
user_path(user)) %>
  <%= user.post.username %>
  <%= user.post.body %>
  <%= image_tag(user.post.photo.url(:medium), style: '') %>
  <% end %>
  <% else %>
  No new posts

Thanks for responding guys. Right now, I'm using the methods that are

I'm getting an error for the user's avatar image. For whatever reason, 
it's not seeing the full user model with attributes included. I'm using 
Carrierwave btw.

 <%= link_to(image_tag(user.avatar.url(:thumb), style: 'text-decoration: 
none;', class: 'round-image-50'), user_path(user)) %>

undefined method `avatar' for #

But, I see that it is loading the information within the instance 
variables.

I don't think you want paginate here, and since you are going to sort
it again later there is no point sorting here either.

> @following_activities << current_user.posts.order('created_at
> desc').all

You want + here not << as you just want to concatenate the arrays,
then you will not need to flatten in the next line.  Also no need to
sort in line above

> @following_activities = @following_activities.flatten.sort_by
> {|post| post.created_at }
> end

As I said above, no need for the flatten

Also, assuming that you have User has_many following_users and User
has_many posts then you should be able to say something like
User has_many following_posts through following_users ...
You will need a bit more on the end get it to work, not exactly sure
what you need there.  Perhaps someone else will know exactly what you
need.  Then you will be able to say
current_user.following_posts
to get all those posts.

So you will be able to say
@following_activities = (current_user.posts +
current_user.following_posts).sort

How about just adding the current_user.id to the following_ids array? You
could then pull all the posts in one shot, and remove the next two lines.

Hi!

I've published a small app which makes it quite easy to get a free and 
trusted SSL certificate.

The app is available at https://tlsify.herokuapp.com/.

It's in an early stage so there are a lot of bugs but the main features 
should work if the request is done correctly.

 - Just insert your domain and your contact email and generate a 
certificate.
 - In the next step you have to prove that you are the owner of the domain. 
(Wait one or two minutes after you created the TXT record!)
 - Copy the certificates into .pem files.

Have fun with your certificates!

Bugs and feedback please to tob...@feistmantl.io!

A lot features will probably follow!

Cheers

Tobias

[Rails] How do I add my own posts plus following users post with Acts_As_Follower Rails 4

[David Williams]

I've been trying to combine my own post with the users that I follow in
chronological order DESC. Can you help me build the proper query method
for it?


What I currently have is the code below

def feed
  following_ids = current_user.following_users.map(&:id)
  @following_activities =
Post.where(user_id:following_ids).order("created_at
desc").paginate(page:params[:page])
@following_activities << current_user.posts.order('created_at
desc').all
@following_activities = @following_activities.flatten.sort_by
{|post| post.created_at }
end

Feed.html.erb
  <% if @following_activities.any? %>
  <% @following_activities.each do |user| %>
  <%= link_to(image_tag(user.avatar.url(:thumb), style:
'text-decoration: none;', class: 'round-image-50-trendy-warrior'),
user_path(user)) %>
  <%= user.post.username %>
  <%= user.post.body %>
  <%= image_tag(user.post.photo.url(:medium), style: '') %>
  <% end %>
  <% else %>
  No new posts
  <% end %>

The approach that I'm using is not causing any server errors. But, I'm
not seeing the post that I've already created, they aren't being loaded.

Since it's still not working, I'd recommend you start checking things 
one-by-one to verify they are working as you expect.

* does the gallery work *other* than the description field? Are there any 
errors / warnings in the browser console? If so, deal with those before 
moving on.

* add a breakpoint inside the 'onslide' handler the documentation provides. 
Are things as expected? Are the "text" and "node" variables getting
