I'm new to Rails. I'm working with Devise and I'm getting this error when I try to sign in
uninitialized constant ActiveSupport::SecureRandom
I'm running Rails 3.2.8 and Devise 2.1.2
Let me know if you need to see anything else.

Try using SecureRandom instead of ActiveSupport::SecureRandom. ActiveSupport::SecureRandom was deprecated in Rails 3.1 and removed in Rails 3.2
May be you are using
Devise.friendly_token
Instead of this use:
SecureRandom.base64(15).tr('+/=', 'xyz')
It may work.

I'm trying to implement nested micropost replies in the Rails Tutorial with Michael Hartl. I've installed the ancestry gem, included has_ancestry in the Micropost model, and restarted the server, but I continue to get this error. Link to github repo and full trace below.

Parameters:
{"parent_id"=>"302"}
You're assigning the id to the parent setter, while you should use parent_id here.
Try changing:
#micropost.parent = params[ :parent_id]
to:
#micropost.parent_id = params[:parent_id]
I'm really just not sure what it means or what I'm supposed to do in order to get the webpage working on my localhost. Right now it is just showing an error that reads "We're sorry, but something went wrong." when I run rails server and open up localhost:3000 in chrome.

The other answers are correct in general. This exception in particular is caused by an incompatibility between older versions of the newrelic_rpm gem and Ruby 2.0. See rails #8885.
Update the newrelic_rpm gem and it should go away.
It is a null reference exception in your method detail_args_for (well technically a Nil reference exception). You are trying to call the method empty? on a variable that has a Nil value, which causes a problem because that isn't defined in nil
You're calling .empty? on a variable that hasn't been initialized somewhere in your detail_args_for method. It's probably to add an additional call to .nil? before checking .empty? if you want to allow Nil values:
if(!someVar.nil? && someVar.empty?)

That quick IRB experiement leads me to the conclusion that your variable json_infos is nil.
Are you sure you don't want docker_path = '/usr/bin/' (with the trailing slash)? Unless you have the directory /usr/bindocker ...
I do get all the time i call the controller in the browser a doublerenderError as listed below. please tell me why.. i do render just once.. and i never have a redirect or something like that :/

You are in an each loop, which is calling Render each pass through the loop.
either do:
def index
render :json => Bezirk.all
end
or
def index
Bezirk.find_each do |bezirk|
... #build up a hash to render
end
render :json => your_built_hash
end
------- EDITED ---
def index
bezirks = []
Bezirk.find_each do |bezirk|
bezirks << bezirk.attributes
end
render :json => {:bezirks => bezirks}
end
Another nooby question - I have these two models in my project:
class Invoice < ActiveRecord::Base
has_many :items
end
and
class Item < ActiveRecord::Base
belongs_to :invoice ,:foreign_key=>'invoice_number',:primary_key=>'invoice_number'
end
So in my controller, I want to add new item to the invoice by pressing a button which is binded to an action. The action will generate a form to let the client fill in the information about the item. I want to something like this in controller:
#invoice.items << Item.new
This operation might be wrong ,but the problem is , Rails tells me that there is undefine method 'items'. Does anybody could give me a hint on how to fix this?

Feedback for the Question:
Thank you for you guys helping me on this mass.I have solve the problem - I found a misspelling (missing 's'), and I have sorry for taking your time.
Thanks again
Did you create these models in your database and give Item an invoice_number?
rails g migration AddInvoiceNumberToItems invoice_number:integer
rake db:migrate
