sqlite3 to postgreSQL migration issues with Rails and ActiveRecord - ruby-on-rails

Prior information: I have very little knowledge in Ruby on Rails and its Gems and Frameworks. So things which seem to be obvious may not be the case to me.
I need to migrate the database from sqlite3 to postgreSQL in our application containing AngularJS in the frontend and Ruby on Rails with ActiveRecord in the backend.
I installed the Ruby Gem pg and changed the database.yml as following:
# This was for sqlite
#adapter: sqlite3
#database: db/gfms.sqlite3
#pool: 5
#timeout: 5000
# This is for postgreSQL
adapter: postgresql
encoding: unicode
database: llqa
pool: 5
username: postgres
password: admin
host: localhost
port: 1234
timeout: 5000
schema_search_path: "gfms"
I'm having several issues now. Some queries return no records where they should, but don't generate an error. But:
A more specific problem I'm having is this error:

The function where the error happens (the line is commented):
def get_list(limit = nil, page = nil)
coll = all
coll = (block_given?) ? (yield coll) : coll
rowcnt = coll.count # This is the line where the error happens
pages = (limit && limit > 0) ? (rowcnt.to_f/limit).ceil : 1
coll = coll.limit(limit) if limit && limit > 0
coll = coll.offset((page-1)*limit) if limit && limit > 0 && page && page > 1
ret = { rows: coll.all.to_a, rowcnt: rowcnt, page: page || 1, pages: pages, limit: limit || 0 }
def ret.serialize(include = nil)
self[:rows].collect! do |row|
hash = include ? (row.serializable_hash(include: include.incllist)) : row.serializable_hash
(hash['code'] && hash['code'].end_with?('(TR)')) ? nil : ((block_given?) ? yield(hash,row) : hash)
end
self[:rows].compact!
return self.rest_success,true,self
end
return ret
end
This is just an example. My question however is: Is there something in the configuration of ActiveRecord, Ruby or postgreSQL itself so it behaves equally like with sqlite3? What needs to be done, if anything?

What is causing this undefined method error in my Ruby on Rails / GraphQL project

I am working on a project with GraphQL for the first time and I've hit a bit of a snag I can't figure out. I have a business model, a user model and an industry model. The business model belongs to both of the other models. Scaffolded view operations run as expected, but when I run a Graph query on businesses and include either of the other two models, it errors out with
undefined method `map' for #User:0x00007fadeb73f140>\nDid you mean?
tap
Here is my definition in query_type.rb:
# get all businesses
field :businesses, [Types::BusinessType], null: false, description: "List of all businesses"
def businesses
Business.all
end
And here is my BusinessType:
module Types
class BusinessType < BaseObject
field :id, ID, null: false
field :name, String, null: false
field :zip_code, String, null: true
field :growth_stage, String, null: true
field :annual_revenue, Integer, null: true
field :first_name, String, null: false
field :last_name, String, null: false
field :email, String, null: false
field :phone, String, null: false
field :industry, type: [Types::IndustryType], null: true
field :user, type: [Types::UserType], null: true
end
end
And here is my Graph query:
{
businesses {
id
name
growthStage
annualRevenue
firstName
lastName
email
phone
zipCode
user {
email
}
industry {
name
}
}
}
here is the stack trace:

I was able to resolve this by changing the following line in business_type.rb:
field :user, type: [Types::UserType], null: false
to
field :user, Types::UserType, null: false
UPDATE: It turns out that the first example should only work with lists of objects and the second with single objects

Issue importing JSON data into database

I've written a script that imports paginated JSON data from an api, encodes the data to UTF-8 and then writes it to a file.
I need to iterate over the data in the file to create records in my database, but am running to an error loading the file so I can do so.
The stack trace isn't telling me much about what's wrong; any help would be greatly appreciated!
code:
require 'net/http'
require 'uri'
require 'json'
require 'faker'
#imports APR User data from the zendesk api, iterates through it and populates the database with it.
uri = URI.parse("https://aprtechsupport.zendesk.com/api/v2/users.json")
request = Net::HTTP::Get.new(uri)
request.content_type = "application/json"
request.basic_auth("cbradford#blah.com", "blah32")
req_options = {
use_ssl: uri.scheme == "https",
}
#response = Net::HTTP.start(uri.hostname, uri.port, req_options) do |http|
http.request(request)
end
res = #response.body
res.force_encoding("utf-8")
resEncoded = JSON.parse(res)
users = resEncoded
#data = {}
#data.merge(users)
results = []
results << resEncoded
puts results
while users["next_page"]
newUri = users["next_page"]
uriLoop = URI.parse(newUri)
puts newUri
requestLoop = Net::HTTP::Get.new(uriLoop)
requestLoop.content_type = "application/json"
requestLoop.basic_auth("cbradford#blah.com", "blah32")
req_optionsLoop = {
use_ssl: uriLoop.scheme == "https",
}
#responseLoop = Net::HTTP.start(uriLoop.hostname, uriLoop.port, req_optionsLoop) do |http|
http.request(requestLoop)
end
dataEncoded = #responseLoop.body
dataEncoded.force_encoding("utf-8")
resLoop = JSON.parse(dataEncoded)
results << resLoop
updateUri = resLoop["next_page"]
users["next_page"] = updateUri
end
puts "hash created Successfully!"
puts results
File.write('blahzendeskusers1.json', results)
puts "File Created Successfully!"
file = File.read('blahzendeskusers1.json')
usersLoop = JSON.load(file)["users"]
usersLoop.each do |a|
User.find_or_create_by(:zendesk_id_int => a["id"], :url => a["url"], :name => a["name"], :email => a["email"],
:phone => a["phone"], :role => a["role"], :default_group_id => a["default_group_id"], :external_id => a["external_id"],
:tags => a["tags"]
)
end

I think you intend to use minimum instead of min? I haven't found a reference to min, so it might be using a different method that uses no parameters.

32651:ERROR comparison of Float with Float failed ruby

I'm new to rails, and I'm getting an error and I can't seem to find were the problem is. Here is the log:

Whenever I go to the file and find that row, there is no each, and I can't understand where the problem is. Can anyone help? More than a fix, I want to understand the problem.
Here is the file:
class Lifetime
attr_reader :values
GROWTH_CUT_OFF = 0.10
def initialize(engaged_users_values)
#values = engaged_users_values
end
def run
growths = growth(values)
return [0] if growths.uniq.first == 0 || growths.empty?
max_growth = max_growth(growths)
dead_growth = least_growth(growths, max_growth)
time_diff = time_diff(values.last['end_time'],
values.first['end_time'])
return [time_diff] unless dead_growth
dead_loc = growths.index(dead_growth)
dead_value = values[dead_loc]
lifetime(values.first, dead_value)
end
def time_diff(last, first)
in_minutes(parse_time(last)-parse_time(first))
end
def parse_time(time)
DateTime.parse(time)
end
def growth(values)
values.each_cons(2).map do |one, two|
one_value = one['value'].to_f
two_value = two['value']
((two_value-one_value)/(one_value)*100).round(2)
end
end
def max_growth(growths)
growths.max
end
def least_growth(growths, max_growth)
growth_cut = growth_cut(max_growth)
growths.select {|g| g <= growth_cut}.first
end
def growth_cut(max_growth)
max_growth*GROWTH_CUT_OFF
end
def lifetime(first_value, last_value)
first = parse_time(first_value['end_time'])
last = parse_time(last_value['end_time'])
result = last-first
[in_minutes(result)]
end
def in_minutes(time)
time.to_f*24*60
end
end

If one of both Floats is NaN then you get this message. So, prevent the NaN case.
We can give you more info if you post the exact code of the error (the max_growth method)

Job failed to load: uninitialized constant Syck::Syck

I am running a method in the background using delayed-job (collectiveideas fork)
The method I am running is shown below, which fetches the price of the isbn:
def update_prices(isbn13)
#amazon = Nokogiri::XML(open("http://www.amazon.com/s/?url=search-alias%3Daps&field-keywords=#{isbn13}"))
price = #amazon.search('span.listprice').first.text.gsub('$', '')
book = Book.find_by_isbn13(isbn13)
book.update_attribute(:amazon_us_price, price)
end
handle_asynchronously :update_prices
Now when I run this, the job is added to the database but encounters an error when running.
The error is quite large, but I think the gist of it comes from the first line:

Any idea what may be causing the error? I have never heard of Syck before.

Include the following lines of code in boot.rb (config\boot.rb)
require 'yaml'
YAML::ENGINE.yamler= 'syck'

For those that this didn't work for, like me, I've found include the Psych gem to handle YAML parsing fixed the issue. See: Delayed_job: Job failed to load: uninitialized constant Syck::Syck
