Ruby OAuth2 timeout error getting Token - ruby-on-rails

I posted this of the issues page for the doorkeeper gem, but looking at it, I wonder if I should post here, any help would be amazing as I am completely stuck
I have been following the wiki on doorkeeper and doing the "Testing your provider with OAuth2 gem" (https://github.com/doorkeeper-gem/doorkeeper/wiki/Testing-your-provider-with-OAuth2-gem)
I am running rails 5.1.4, ruby 2.4.1, doorkeeper gem 4.2.6 and oauth2 v1.4.0
I am having issues trying to do what is done in the testing wiki in code, which is get an auth token
My sessions controller:
def new
session[:state] = 'some state sent from amazon'
session[:client_id] = 'some client id'
session[:client_secret] = 'some client secret'
session[:redirect_uri] = "#{request.base_url}/oauth/callback"
end
def create
user = User.find_by(email: params[:session][:email].downcase)
if user && user.authenticate(params[:session][:password])
if user.activated?
log_in user
redirect_to client.auth_code.authorize_url(:redirect_uri => session[:redirect_uri])
end
end
end
#route for /oauth/cllback comes here
def callback
token = client.auth_code.get_token(params[:code], :redirect_uri => session[:redirect_uri])
# testing print to screen
render json: token
end
private
def client
OAuth2::Client.new(session[:client_id], session[:client_secret], :site => request.base_url)
end
So as a user i log in, I authorise the app and then it times out and I get the following log for the whole flow:
Started GET "/login?client_id=<client_id>&response_type=code&state=<amazon state>&redirect_uri=https%3A%2F%2Fpitangui.amazon.com%2Fapi%2Fskill%2Flink%2FM2X1TLJOHDU07S" for 5.175.83.20 at 2017-10-23 13:36:35 +0100

even If i put that uri into browser and it returns the access token:

Again any help would be amazing!

So I found in my Dev Environment, if i stop using puma and rails server and started using POW, the issue went away. I checked if puma was running as single thread but it was running 5 threads, so not sure why this was happening.

It seems you have messed a little with your parameters. You sent nested parameters on your form like this:
"user"=>{"name"=>"Sohail ", "phone_number"=>"(11", "organization"=>"11", "email"=>"user#test.com", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]", "current_password"=>"[FILTERED]"}, "commit"=>"Update"}
However your permited parameters assume you are nesting everything on a :account_update key.
So you could either change the key sent on your form, or use this sanitizer:
def configure_account_update_params
devise_parameter_sanitizer.permit(:account_update, keys: [:name,:property,:admin,:phone_number,:organization,:gender,:profile_pic,:birthday])
end

Why is my model not updating in my Rails API?

I am developing an API in Rails and interacting with it from another Rails application. Up to now everything has been working correctly, using POST and GET to authenticate users, create records and retrieve data. But now I'm having trouble getting the PUT operation to update a record. It appears it is calling the API correctly and the API is returning a 200 response, but looking at the logs it doesn't look like Rails is even executing an UPDATE statement. The strangest thing is that there are no errors or warning.
Here is the Log. (Data is faker data so I'm not bothering to redact it)

You can see the parameter data in the log. The controller action is pretty simple:

def update
if #affiliate.update(affiliate_params)
render json: #affiliate
else
render json: #affiliate.errors, status: :unprocessable_entity
end
end
Thanks in advance for any help.
As it turns out, for whatever reason, the put method required me to identify the content type in the header. Post wasn't doing this, but changing the line in my HttParty call fixed the issue:
response = HTTParty.put(put_uri, body: #this_data.to_json, headers: { 'Content-Type' => 'application/json', 'Authorization' => #token })

Devise - sign_in() not working rails 5.2.0

Created new ruby app
in my controller im trying to sign in a user like so
email = params[:email]

if user

redirect_to root_path
else
render json: {success: false}
end
The user is going into sign_in

I've done this numerous times, i'm not sure why its not working, any ideas?
Well after an hour of going crazy
i had a random line in my routes
devise_for :users
with no end doing nothing and it was causing this issue.
after removing that everything is fine.

rails validates_format_of with IP addresses

I'm allowing a user to enter IP addresses in an input field which may be of different types delimited by a comma, such as (in no particular order):
192.168.1.1,192.168.2.1-25,10.10.10.0/24,192.168.1.2
This 'string' would get saved in my DB under device.ips_to_scan.
I want to validates_format_of on these, but am finding it a little difficult to write a regex that seems to work in rails, while it does work on regex101 (https://regex101.com/r/nf2bnM/1):
validates_format_of :ips_scan, with: /\A([0-9]{1,3}\.){3}[0-9]{1,3}(\/([1-2][0-9]|[0-9]|3[0-2]))?(-([0-9]{1,3}))?,?\Z/i, on: :update
This one is expected to fail:

Last thing I can think of, is that I do have strong parameters, but I'm permitting ips_scan, so that this shouldn't be an issue:
def update
if #device.update(device_params)
flash[:notice] = 'Successful update'
respond_with :edit, :device
else
flash[:warning] = 'Unable to update'
respond_with :edit, :device
end
end
private def device_params
params.require(:device).permit(:token, :ips_scan, :ips_exclude)
end
I'm hoping you rubyist's out there have a eloquent solution. The first thought that comes to mind is that I have to split the string, and check each element sequentially to ensure it matches instead.
While I'm still open to a nice eloquent one-liner within the Model itself, I was able to get this working through creating a concern:
models/concerns/ip_validator.rb
class IpValidator < ActiveModel::Validator
def validate(record)
ips = record.ips_scan.split(',')
ips.each do |ip|
/([0-9]{1,3}\.){3}[0-9]{1,3}(\/([1-2][0-9]|[0-9]|3[0-2]))?(-([0-9]{1,3}))?/ =~ ip
record.errors.add(:ips_scan, ' is not valid') unless $LAST_MATCH_INFO
end
end
end
The call in my model now looks like:
validates :ips_scan, :ips_exclude, ip: true, on: :update
You can use this method in your custom validator to check an IP address
require 'ipaddr'
def valid_ip_addr?(ip_addr)
IPAddr.new(ip_addr)
true
rescue IPAddr::InvalidAddressError => _error
false
end

Can you tell me why it not change the role?
If you want to know more informatian, please let me know. Thank you very much for helping me.
It looks you have some model callback (may be before_save) which is restricting to update the records.
You can use update_column or update_columns to bypass the callbacks/validations and directly make a update query to your db.
def approve_vip
#user = User.find(params[:user_id])
#user.update_columns(is_vip: true)
redirect_to :back
end
You need to read error's message. Probably the user's validation is failed.
def approv!
update_attributes!(is_vip: true)
end
This code give you exception with the error's message.
