Ruby each block next when exception or error is raised - ruby-on-rails

I have the following method in my rake task.
def call
orders = Spree::Order.complete.where('completed_at >= :last_day', last_day: Time.now - 30.days)
orders.each do |order|
order_tracking = order.shipments.first.tracking
next if order_tracking.nil?
shipment = order.shipments.first
results = fedex.track(tracking_number: order_tracking)
tracking_info = results.first
status = tracking_info.status.to_s
delivery_date = tracking_info.delivery_at
shipment.is_delivered = delivered?(status)
shipment.date_delivered = delivery_date
shipment.save
puts "-> Shipping status was updated for #{order.number}"
end
end
If there is an order with no tracking number I skipping it with next on line 5.
My question: How would I do next if a tracking number is invalid and the following error is raised:
Fedex::RateError: Invalid tracking number.
Ideally I would like to change line 5 to:
next if order_tracking.nil? || order_tracking.raised(Fedex::RateError) # something like that
Thank you in advance.
Also RateError is raised here:
def process_request
api_response = self.class.post(api_url, :body => build_xml)
puts api_response if #debug == true
response = parse_response(api_response)
if success?(response)
options = response[:track_reply][:track_details]
if response[:track_reply][:duplicate_waybill].downcase == 'true'
shipments = []
[options].flatten.map do |details|
options = {:tracking_number => #package_id, :uuid => details[:tracking_number_unique_identifier]}
shipments << Request::TrackingInformation.new(#credentials, options).process_request
end
shipments.flatten
else
[options].flatten.map do |details|
Fedex::TrackingInformation.new(details)
end
end
else
error_message = if response[:track_reply]
response[:track_reply][:notifications][:message]
else
"#{api_response["Fault"]["detail"]["fault"]["reason"]}\n--#{api_response["Fault"]["detail"]["fault"]["details"]["ValidationFailureDetail"]["message"].join("\n--")}"
end rescue $1
raise RateError, error_message
end
end

added:
private
def fedex_track(tracking)
fedex.track(tracking_number: tracking)
end
And changed results on line 7 to:
results = fedex_track(order_tracking) rescue next

How does recalling a variable work in a method?

I have the following method:
vendor_orders = VendorOrder.where(id: params[:vendor_order_ids])
orders = Order.find(vendor_orders.pluck(:order_id))
products = Product.joins(:vendor_product).where(vendor_products:{vendor_id: current_user.id }).ids #get all vendor_products that match current_user.vendor
line_items = LineItem.joins(:shop_product).where(cart_id: orders.pluck(:cart_id), fulfillment_status: "processing", shop_products: {product_id: products}).where.not(fulfillment_status: "canceled")
messages = []
n = 0
puts "line items: #{line_items.count}" #puts out 1
line_items.map do |li|
if li.update_attribute(:fulfillment_status, params[:mass][:fulfillment_status])
n+=1
else
messages << "#{vendor_order.vendor_order_token}"
end
end
puts "line items2: #{line_items.count}" #puts out 0
if n == line_items.count
flash.keep[:notice] = "Update for #{vendor_orders.count} order(s) and #{n} product(s) successful"
else
flash.keep[:notice] = "Failed update for Order: #{messages.join if messages.any?}"
end
puts "line item3 #{line_items.count}" #puts out 0
respond_to do |format|
format.html { redirect_to vendor_orders_path }
end
The question i have is about the puts
When calling line_items.count after I update the line_items to then not match the variable, does it recall line_items from above?
Is this true? I always assumed once something was defined and passed, it would stay at the rate, unless redefined.
Marek solved the issue by letting me know .count is a call to the database which will then call what you defined previously.
To solve this, I just use line_items_count = line_items.count and use that above any alterations to check against it.

Cant found model with out an ID in rails 3.2.12

i ve this method. I m not at all able to understand the error which is
Couldn't find Company without an ID
in ActiveRecord::RecordNotFound in CustomersController#bulk_create
This method is written to create customers for a company in bulk by taking their name and numbers in format name:number.
The method is as follows:
def bulk_create
res = ""
comp_id = params[:customer][:selected_companies].delete_if{|a| a.blank?}.first
comp = Company.find(comp_id)
s = SentSmsMessage.new
s.set_defaults
s.data = tmpl("command_signup_ok", customer, comp) unless params[:customer][:email].length > 0
s.data = params[:customer][:email] if params[:customer][:email].length > 0
s.company = comp if !comp.nil?
s.save
unless comp_id.blank?
params[:customer][:name].lines.each do |line|
(name, phone) = line.split(/\t/) unless line.include?(":")
(name, phone) = line.split(":") if line.include?(":")
phone = phone.gsub("\"", "")
phone = phone.strip if phone.strip.to_i > 0
name = name.gsub("\"", "")
name = name.gsub("+", "")
phone = "47#{phone}" if params[:customer][:active].to_i == 1
customer = Customer.first(:conditions => ["phone_number = ?", phone])
if customer.nil?
customer = Customer.new
customer.name = name
# customer.email
# customer.login
# customer.password
customer.accepted_agreement = DateTime.now
customer.phone_number = phone
customer.active = true
customer.accepted_agreement = DateTime.now
customer.max_msg_week = params[:customer][:max_msg_week]
customer.max_msg_day = params[:customer][:max_msg_day]
customer.selected_companies = params[:customer][:selected_companies].delete_if{|a| a.blank?}
res += "#{name} - #{phone}: Create OK<br />" if customer.save
res += "#{name} - #{phone}: Create failed<br />" unless customer.save
else
params[:customer][:selected_companies].each do |cid|
new_company = Company.find(cid) unless cid.blank?
if !new_company.nil?
if !customer.companies.include?(new_company)
customer.companies << new_company
if customer.save
res += "#{name} - #{phone}: Customer exists and the customer was added to the firm #{new_company.name}<br />"
else
res += "#{name} - #{phone}: Customer exist, but something went wrong during storage. Check if the client is in the firm.<br />"
end
else
res += "#{name} - #{phone}: Customer exists and is already on firm #{new_company.name}<br />"
end
end
end
end
s.sms_recipients.create(:phone_number => customer.phone_number)
end
s.save
s.send_as_sms
#result = res
respond_to do |format|
format.html { render "bulk_create"}
end
else
#result = "You have not selected any firm to add these users. Press the back button and try again."
respond_to do |format|
format.html { render "bulk_create"}
end
end
end
I want to update one situation here. That when i submit the form blank then it gives this error. Also if i filled the form with the values then its show the situation which the method is returning in case of fail.
res += "#{name} - #{phone}: Create failed <br />"
The tmpl method
private
def tmpl(setting_name, customer, company = nil)
text = ""
if customer.companies.count > 0
sn = "#{setting_name}_#{#customer.companies.first.company_category.suffix}".downcase rescue setting_name
text = Setting.value_by(sn) rescue ""
end
textlenth = text.length rescue 0
if textlenth < 3
text = Setting.value_by(setting_name) rescue Setting.value_by("command_error")
end
return fill_template(text, customer, company)
end
From the model customer.rb
def selected_companies=(cmps)
cmps.delete("")
# Check the old ones. Make a note if they are not in the list. If the existing ones are not in the new list, just remove them
self.companies.each do |c|
self.offer_subscriptions.find(:first, ["customer_id = ?", c]).destroy unless cmps.include? c.id.to_s
cmps.delete c.id.to_s if cmps.include? c.id.to_s
end
# Then create the new ones
cmps.each do |c2|
cmp = Company.find(:first, ["id = ?", c2])
if cmp && !c2.blank?
offerSubs = offer_subscriptions.new
offerSubs.company_id = c2
offerSubs.save
end
end
end
def selected_companies
return self.companies.collect{|c| c.id}
end
The association of customer is as follows:
has_many :offer_subscriptions
has_many :companies, :through => :offer_subscriptions
This code is written by the some one else. I m trying to understand this method but so far not being able to understand this code.
Please help.
Thanks in advance.
You are getting 'Couldn't find Company without an ID' error because your Company table doesn't contain record with id = comp_id
Change comp = Company.find(comp_id) to comp = Company.find_by_id(comp_id).
This will return nil instead of an error.
Add comp is not nil condition is already handled in your code.
Your comp_id line is returning nil.
comp_id = params[:customer][:selected_companies].delete_if{|a| a.blank?}.first
Post the params that get passed to this function and we could hopefully find out why. In the meantime you could enclose the block in a begin - rescue block to catch these errors:
begin
<all your code>
rescue ActiveRecord::RecordNotFound
return 'Unable to find a matching record'
end
try this:
comp = ""
comp = Company.find(comp_id) unless comp_id.nil?
instead of comp = Company.find(comp_id)
further nil checking present in your code.
Reason being
params[:customer][:selected_companies].delete_if{|a| a.blank?} = []
so [].first = nil
therefor, params[:customer][:selected_companies].delete_if{|a| a.blank?}.first = nil
and comp_id is nil
So check the log file and check what is coming in the parameter "selected_companies"
when you will find the parameter, everything will be understood well....

Rails Fixnum Error

I have a simple query that Rails seems to be interpreting as a fixnum, but I'm not sure why. My code looks like this:
#user_with_points = Point.select("sum(points) as points, user_id").order("points desc").group("user_id")
#user_with_points.each_with_index do |user_with_point, index|
When I add puts #user_with_points, it shows:
#<Point:0x6360138>
#<Point:0x6322f38>
However, I'm receiving this error this error:
NoMethodError: undefined method 'each' for 75:Fixnum
adding Entire Code
def self.update_overall_rank_and_points
#user_with_points = Point.select("sum(points) as points, user_id").order("points desc").group("user_id")
rank = 0
points = 0
#user_with_points.each_with_index do |user_with_point, index|
#user = User.find(user_with_point.user_id)
if user_with_point.points != points
points = user_with_point.points
rank += 1
end
#user.rank = rank
#user.points = user_with_point.points
#user.save
end
end
Your query is returning a scalar value which the sum of points as an integer. The total of your query happens to be 75, hence the error. Therefore you can't do an each against it since it's not an enumeration.
Try:
#user_with_points = Point.sum(:points, :group => :user_id, :order => 'sum(points)')
#user_with_points.each do |user_id, points|
#...
user = User.find(user_id)
if user.points != points
puts "not equal!"
end
end

Ruby on rails rake task not returning up-to-date model info

While building a billing system I encountered the following problem:
In scheduler.rake :
#users.each do |user|
begin
puts "CALCULATING COSTS =========="
costs = user.total_billable_price_per_month(Time.now)
lead_count = user.total_billable_leads_count(Time.now)
click_count = user.total_billable_clicks_count(Time.now)
puts "CREATING NEW INVOICES ======="
#invoice = user.invoices.new
# if user.free_credits
# invoice.total_price_in_cents = 0
# else
# invoice.total_price_in_cents = costs.cents
# end
#invoice.total_leads = lead_count
#invoice.total_clicks = click_count
#invoice.total_price_in_cents = costs.cents
# Als de vorige factuur onder de 10 euro was, dan geld bij huidige factuur optellen
if user.invoices.last && user.invoices.last.total_price_in_cents < 1000
puts "Bedrag onder 10 euro"
puts "Last invoice = #{user.invoices.last.total_price_in_cents}"
#invoice.total_price_in_cents += user.invoices.last.total_price_in_cents
end
puts "SAVING INVOICE FOR #{user.name} with ID = #{user.id}"
# Factuur saven
#invoice.save
#Als de factuur hoger of gelijk is als 10euro, dan factuur aanmaken
if #invoice.total_price_in_cents >= 1000
#Moneybird factuur versturen
puts "COSTS ARE HIGHER THAN 10 EURO, CREATING MONEYBIRD INVOICE"
moneybird_invoice = MoneybirdInvoice.new
sleep(15)
moneybird_invoice.contact_id = MoneybirdContact.find_by_customer_id(user.id).id
sleep(15)
moneybird_invoice.details_attributes = [
{ :description => "Aantal leads", :amount => lead_count, :price => user.lead_price.cents.to_f/100},
{ :description => "Aantal clicks", :amount => click_count, :price => user.click_price.cents.to_f/100}
]
puts "TRYING TO SAVE MONEYBIRD INVOICE"
if moneybird_invoice.save && moneybird_invoice.put(:send_invoice)
puts "SUCCESFULLY SAVED INVOICE"
#GET UPDATED PAY URL
#sent_mb_invoice = MoneybirdInvoice.get(moneybird_invoice.id)
sleep(15)
#invoice.update_attributes(:moneybird_invoice_id => #sent_mb_invoice['invoice_id'], :moneybird_pay_url => #sent_mb_invoice['pay_url'])
else
puts "MONEYBIRD INVOICE FAILED"
puts moneybird_invoice.errors.inspect
end
else
# GEEN MONEYBIRD FACTUUR AANMAKEN
end
rescue
puts "ER IS IETS FOUT GEGAAN MET FACTUREREN USER ID = #{user.id} & NAME = #{user.name}"
puts #invoice.errors.inspect
end
end
This piece of code should constantly increment each time the rake task is run, except when the total amount reaches > 1000.
if user.invoices.last && user.invoices.last.total_price_in_cents < 1000
puts "Bedrag onder 10 euro"
puts "Last invoice = #{user.invoices.last.total_price_in_cents}"
#invoice.total_price_in_cents += user.invoices.last.total_price_in_cents
end
The code above always puts "Last invoice = 100" => This should increment each time the rake tasks is run
Every new invoice still has the same total_price_in_cents (when I'm expecting that it should increment).
What is going on ?
EDIT: Added after code upadte:
In your updated code, it looks like you were calling user.invoices.last after you called user.invoices.new, this is why it always returned the same value.
Create a variable #last_invoice = user.invoices.last before call user.invoices.new.
ORIGINAL ANSWER:
In your original code posting, it looks like your save call on #invoice happened outside the loop -- I believe you're only saving it once.
task :create_invoices => :environment do
# Begin the loop for each use
User.all.each do |user|
#invoice = user.invoices.build
#If last bill < 1000
if user.invoices.last && user.invoices.last.total_price_in_cents < 1000
puts "Last invoice = #{user.invoices.last.total_price_in_cents}"
#invoice.total_price_in_cents += user.invoices.last.total_price_in_cents
#invoice.save
end # end 'if' statement
end # end loop for all users
end # end task definition
So you loop though the users table, but never save updates -- except for the very last time after you exit the loop

Gem Resque Error - Undefined "method perform" after Overriding it form the super class

First of all Thanks for you all for helping programmers like me with your valuable inputs in solving day to day issues.
This is my first question in stack overflow as I am experiencing this problems from almost one week.
WE are building a crawler which crawls the specific websites and extract the contents from it, we are using mechanize to acheive this , as it was taking loads of time we decided to run the crawling process as a background task using resque with redis gem , but while sending the process to background I am experiencing the error as the title saying,
my code in lib/parsers/home.rb
require 'resque'
require File.dirname(__FILE__)+"/../index"
class Home < Index
Resque.enqueue(Index , :page )
def self.perform(page)
super (page)
search_form = page.form_with :name=>"frmAgent"
resuts_page = search_form.submit
total_entries = resuts_page.parser.xpath('//*[#id="PagingTable"]/tr[2]/td[2]').text
if total_entries =~ /(\d+)\s*$/
total_entries = $1
else
total_entries = "unknown"
end
start_res_idx = 1
while true
puts "Found #{total_entries} entries"
detail_links = resuts_page.parser.xpath('//*[#id="MainTable"]/tr/td/a')
detail_links.each do |d_link|
if d_link.attribute("class")
next
else
data_page = #agent.get d_link.attribute("href")
fields = get_fields_from_page data_page
save_result_page page.uri.to_s, fields
#break
end
end
site_done
rescue Exception => e
puts "error: #{e}"
end
end
and the superclass in lib/index.rb is
require 'resque'
require 'mechanize'
require 'mechanize/form'
class Index
#queue = :Index_queue
def initialize(site)
#site = site
#agent = Mechanize.new

if #site.url
url = #site.url
log "Opening #{url} as a data page"
#page = #agent.get(url)
#perform method should be override in subclasses
#data = self.perform(#page)
else
#some sites do not have "datapage" URL
#for example after login you're already on your very own datapage
#this is to be addressed in 'perform' method of subclass
#data = self.perform(nil)
end
rescue Exception=>e
puts "Failed to parse URL '#{url}', exception=>"+e.message
set_site_status("error "+e.message)
end
#overriding method

end
def save_result_page(url, result_params)
result = Result.find_by_sql(["select * from results where site_id = ? AND ref_code = ?", #site.id, utf8(result_params[:ref_code])]).first
if result.nil?
result_params[:site_id] = #site.id
result_params[:time_crawled] = DateTime.now().strftime "%Y-%m-%d %H:%M:%S"
result_params[:link] = url
result = Result.create result_params
else
result.result_fields.each do |f|
f.delete
end
result.link = url
result.time_crawled = DateTime.now().strftime "%Y-%m-%d %H:%M:%S"
result.html = result_params[:html]
fields = []
result_params[:result_fields_attributes].each do |f|
fields.push ResultField.new(f)
end
result.result_fields = fields
result.save
end
#rows_parsed +=1
msg = "Saved #{#rows_parsed}"
msg +=" of #{#rows_total}" if #rows_total.to_i > 0
log msg
return result
end
end
What's Wrong with this code?
Thanks
