[Rails] Re: Has anyone setup Acts_as_Follower Gem Successfully?

[David Williams]

I got it working, but now, I just have to add AJAX.

  <% if user_signed_in? %>
  <% if current_user.following?(@user) %>
  <%= link_to "Unfollow", unfollow_user_path(@user), class: 
'btn btn-danger' %>
  <% else %>
  <%= link_to "Follow", follow_user_path(@user), class: 'btn 
btn-success' %>
  <% end %>
  <% end %>

Are you using Paperclip or other gem ? I'm asking because Paperclip 
resolved this issue and you don't have think about this other fields and

When they refer to attachments in Paperclip, what they mean is that you are 
attaching a file to a Rails model instance. The model instance is saved in the 
database, and the file in the filesystem, so it is an attachment if you look at 
it the way they mean you to.

Can you try to come up with a better approach, and then show me how I

And how is the file supposed to actually get uploaded, i changed the create 
action in my pictures controller to look like this but the file didn't get 
uploaded

  def create
@picture = Picture.new(picture_params)
if @picture.save
  uploader = PictureUploader.new
  picture = params[:imageable]
  uploader.store!(picture)
  redirect_to user_profile_path(current_user.id, 
current_user.profile.id), notice: "The picture #{@picture.name} has been 
uploaded."
else
  render "new"

The behavior you've described doesn't match the code. The `:locals => { 
:user => @user }` part of those render calls should have made `user` 
available in the partial. If you're switching to using the instance 
variable, make sure to remove all the references to the local variable 
(there's still one in the call to `user_follow_path`).


Afterwards it started to say undefined method id for 
> nil:NilClass. Why am I unable to use the follow/unfollow buttons?

That message isn't particularly helpful without a stack trace; something is 
calling `id` on an object that's nil. A stack trace would be helpful for 
finding the cause.

Regarding your followup message ("I want the buttons to show, but only 
redirect users that are not logged in."), that may require some rethinking 
of your approach. Doing a redirect from the `FollowsController#create` 
method will not do what you want (the browser will follow the redirect and 
attempt to parse the result as Javascript).

Re: [Rails] Dynamic Fields and Models Architecture

[Usman Shahid]

Ok, i'll explain this with a hypothetical scenario. Suppose the requirement
is that we need to create a portal to provide stats of different products
available in the market. And suppose you get data periodically from
different places in spreadsheets.Each spreadsheet contains data for one
kind of product, e.g cellphones, television etc and each kind of product
has different fields. There can be hundreds of thousands of records in one
spreadsheet so it must structured for efficient retrieval, however data is
read-only, there'll be no write operations.On each data set we need to be
able to perform generic, predefined read operations. e.g. selection of
subsets fulfilling certain criteria, sorting, grouping, aggregates. For
example, I should be able to write a generic functions, which gets table
name, field name and returns count of unique values in that field. this can
be used to count televisions with different resolutions and also to count
books by different authors. here resolution and author is unique field of
respective datasets.

The problem I'm facing is that I've to create a different tables and
respective models every time a new product type is added. Even though the
models are essentially performing the same operations.

Thanks for the response.

Usman

#new is the method used for showing the form, and is a get not a post,
 form_for needs the route for posting to the create method.  If you
don't supply a url in the call of form_for it assumes pictures_path
which must have been provided using resources: pictures for at least
the create method.  See [1] for details.  I expect that is described
in the Rails Guides also.

[Rails] Pb with render to breaking out of an iframe

[Jer]

Hi,

I have an application who open an other web site in an iframe where my 
users have some work to do and have to clic on a button when the job is 
done.
This action send me a get http.
In the controller I use this command to breaking out of the iframe :

render :text => breakout_path(refinery.scores_score_path(@score)) , 
content_type: :html

private
  def breakout_path(path)
"parent.location.href = '#{path}';"
  end

My problem is that solution works fine on Firefox and Safari but fails in 
Chrome, IE and Opera.

In Chrome and Opera, the iframe stay and print the text render interpreted :

parent.location.href = '/scores/18';

For Internet Explorer it's worst, on clic it ask to dowload a file where 
the name is the controller name and contain the text interpreted too.

I tried to change my  into . Same behaviors.

Here is my environnement :
Ubuntu desktop 14.04
Rails 4.2.4
Ruby 2.0.0p645
Refinerycms 3.0

Thanks for helping me ;) I'm a beginner in web and rails development :\

Re: [Rails] Re: form_for @object with carrierwave upload form

[Przemek Kosakowski]

Many pictures for user profile ? I can't agree but okay. If you have 
many pictures for one user then you should create Gallery model instead 
of Picture. Even on fb user be able to have only one profile picture.


But I don't judge, maybe your solution is effective.

That route doesn't add the `pictures_path` named route. Try adding `as:
'pictures'` option.

Also note that neither the action name nor route you specified follows
rails standard convention[1].

Re: [Rails] form_for @object with carrierwave upload form

[Przemek Kosakowski]

Look on below situation:

class User < ActiveRecord::Base
has_one :profile, :autosave => true
end

class Profile < ActiveRecord::Base
belongs_to :user
has_attached_file :picture,
:styles => { medium: "300x200>", thumb: "100x100>" },
  :storage => :s3,
  :s3_credentials => Proc.new{|a| 
a.instance.s3_credentials}
validates_attachment_content_type :picture, content_type: 
/\Aimage\/.*\Z/

end

this two class + paperclip and that's enough. I think You don't need 
extra model for keeping user profile picture, you can easily add column 
"picture" in Your Profile model.

Have you defined that route in routes.rb (via resources: pictures
for example)?

I agree with Przemek that you would probably be better off using
paperclip for uploading.  It makes life very easy.

I wouldn't disagree   Here's the route:   post 
'users/:id/profiles/:id/pictures/new' => 'pictures#new'

Re: [Rails] form_for @object with carrierwave upload form

I see you trying upload some picture, please use this gem [1]. You be 
able in easy way customize your picture uploader.


[1]: paperclip 

Have you relation between user -> profile -> picture ?
