| How to Generate Standard Attribute Setters for Rails Posted: 18 Aug 2016 07:46 AM PDT I have many strings in my application's models, each should not contain any leading, trailing and duplicate blanks. In order to ensure this, I created separate attribute setter methods for each attribute: def label=( text ) write_attribute( :label, text.strip.squeeze(' ')) end def description=( text ) write_attribute( :description, text.strip.squeeze(' ')) end ...
There should be a more elegant, DRYer way. Including a check for nil. |
| I18n how to translate multiple lookup scopes Posted: 18 Aug 2016 07:40 AM PDT How would I translate using multiple scopes?(<-- maybe not to right terminology) Assume I have these two yml files: en.yml en: activerecord: attributes: table_one: field_one: Field one custom.en.yml en: activemodel: attributes: table_one: field_two: Field TWO
If I call: I18n.translate(:field_one, :scope => [:activemodel ,:attributes, :table_one])
How do i change this to use a lookup with my translate scope to look under activerecord as well? I have tried: lookups = [] lookups << ["activerecord.attributes.table_one.field_one"] lookups << [:field_one, :scope => [:activerecord, :attributes, :table_one]] lookups << [self.human_attribute_name(:field_one)] I18n.translate(:field_one, :scope => [:activemodel ,:attributes, :table_one], :default => lookups)

| Including dynamic json-ld tags in Rails app Posted: 18 Aug 2016 07:11 AM PDT I have the following snippet in my show.html.erb <script type="application/ld+json"> { "@context": "http://schema.org", "@type": "Person", "name": "<%= @person_name %>", "logo": "<%= @person_img_url %>", "membersOf":[ { <%= @person_orgs.each do |group| %> "@context": "http://schema.org", "@type": "Organization", "name": "<%= group[:name] %>" "logo": "<%= group[:img_url] %>", "url": "https://siftery.com/groups/<%= group[:handle] %>" <% end %> } ] }

| Validation Error Messages for belongs_to Assocations made easy Posted: 18 Aug 2016 07:04 AM PDT I have quite some belongs_to associations in my application, some of them are optional (i.e. the association could be nil), some are mandatory (association must be a valid parent record. My initial approach was to validate the given id using my own validation method (here for a mandatory association) belongs_to :category validates :category_id, presence: true validate given_category_exists def given_category_exists if category_id.present? errors.add( :category_id, 'must be present' ) \ Category.exists?( category_id ) end end
Then I found out that Rails would do this for me if I would use the presence check on the association so I could omit my own validation method: belongs_to :category validates :category, presence: true
But now, the generated error message would simply state: Category can't be blank. The problems here are: (1) Can I provide a more useful message? (2) How can I insert my own translation for the attribute? Category is the default label generated from the validates method, can't be blank is the default error text for :blank. Another problem with this: The related input field in the form is not marked as 'field_with_errors' as this field is identified with the attribute's name, not the association's name. Using the standard way of doing things, I would add an additional attribute to my I18n translation file for the name of the association category and adding a replacement for the standard message: en: activerecord: models: attributes: my_model: category_id: 'This Category' category: 'This Category' errors: models: my_model: attributes: category: blank: 'must be specified.'
Lots of lines where things can go wrong. And I did not like the idea to add superficial attributes which are actually not attributes but names of associations. Is there an easier way? |
| Rails has_many through order by join fails on includes Posted: 18 Aug 2016 06:32 AM PDT What is the proper way to implement order in a through table so that I can also use it in an includes? It appears you can do this from the docs and some previous questions. However, it is failing when using :includes class DoctorProfile has_many :doctor_specialties has_many :specialties, -> { order 'doctor_specialties.ordinal' }, through: :doctor_specialties class Specialty has_many :doctor_specialties has_many :doctor_profiles, through: :doctor_specialties class DoctorSpecialty < ActiveRecord::Base belongs_to :doctor_profile belongs_to :specialty
I'm able to call DoctorProfile.first.specialties which generates the correct SQL. DoctorProfile Load (0.7ms) SELECT "doctor_profiles".* FROM "doctor_profiles" ORDER BY "doctor_profiles"."id" ASC LIMIT 1 Specialty Load (0.6ms) SELECT "specialties".* FROM "specialties" INNER JOIN "doctor_specialties" ON "specialties"."id" = "doctor_specialties"."specialty_id" WHERE "doctor_specialties"."doctor_profile_id" = $1 ORDER BY doctor_specialties.ordinal [["doctor_profile_id", 1]]
However, when calling DoctorProfile.includes(:specialties).first I receive the following error: ActiveRecord::StatementInvalid: PG::UndefinedTable: ERROR: missing FROM-clause entry for table "doctor_specialties" LINE 1: ...lties" WHERE "specialties"."id" IN (69) ORDER BY doctor_spe... ^ : SELECT "specialties".* FROM "specialties" WHERE "specialties"."id" IN (69) ORDER BY doctor_specialties.ordinal
If I remove the order in the has_many relationship I'm able able to successfully make the query DoctorProfile.includes(:specialties).first Why is this failing with the includes? How can I make it work? |
| Thinking Sphinx - can't get exact match first Posted: 18 Aug 2016 06:06 AM PDT I have quite simple thinking sphinx setup: Indeces: indexes first_name, :sortable => true indexes last_name, :sortable => true indexes family_name, :sortable => true indexes born_date, :sortable => true indexes death_date, :sortable => true
There are some other related models in it but thats not the case. Thats the riddle I use: Riddle::Query.escape( URI.decode(params[:search]) ), :star => true, :per_page => params[:per_page], :page => params[:page], :ranker => :sph04, :match_mode => :phrase, :order => ('death_date DESC')
What I'm trying to achieve is exact matches first on the list. Now when I search for "Anna" I get all mixed like "Hanna", "Anna-Lisa" before "Anna". It's even worst when I remove 'order'. I've tried several rankers and mach modes with no luck. I would be perfect if I get exact mach on top and sorted by other attribute (date), and other matches after it, also sorted by date. Only solution that came to my head now is sort by result length (shorter is closer to exact match), but maybe there is some better solution? Any clues how to fix this? |

| Tracking stats for API Posted: 18 Aug 2016 04:38 AM PDT I am currently developing a REST API in Rails 5. I am wondering if there is a gem or self-hosted tool (preferably not Google or a service that requires external data sharing) that I can use to provide usage statistics of my API (url, parameters provided, response times, HTTP status and, if possible, user_id etc). My goal with this, is to determine which methods/functionality are used most, how these methods are performing and where I should plan optimizations and refactoring. |

| JSON ParseError unexpected token Posted: 18 Aug 2016 04:26 AM PDT I'm trying to consume an API within a big loop. The code is pretty straightforward Video.find_each(:batch_size => 50) do |video| # video_details = HTTParty.get("http://www.domain.com/webmasters/video_by_id?id=#{video.video_id}&thumbsize=medium") video_details = Curl::Easy.perform("http://www.domain.com/webmasters/video_by_id?id=#{video.video_id}&thumbsize=medium") video_data = video_details.body_str video_details = JSON.parse( video_data ) # video.publish_date = video_details['publish_date'] # video.save end
it works fine for first 16 iterations, but the it throws this error JSON::ParserError 784: unexpected token at '<html><head><script type="text/javascript">
Any idea why does it happen after 16th call? |
| Customize Shrine gem JSON response Posted: 18 Aug 2016 04:08 AM PDT I'm using shrine gem in my rails app for for file uploading. I want to integrate this gem with fineuploader front-end library to enhance the user experience while uploading the files. I'm able to integrate it to an extent that I'm able to upload files through fineuploader front-end via shrine server-side code to my s3 bucket. Now, on a successful upload I receive a 200 status code with JSON response which appear something like following: {"id":"4a4191c6c43f54c0a1eb2cf482fb3543.PNG","storage":"cache","metadata":{"filename":"IMG_0105.PNG","size":114333,"mime_type":"image/png","width":640,"height":1136}}
But the fineuploader expects a success property in JSON response with a value of true in order to consider this response successful. So I need to modify this 200 status JSON response to insert this success property. For this, I asked the author of shrine gem and he advised me to use this code in shrine initializer file: class FineUploaderResponse def initialize(app) @app = app end def call(env) status, headers, body = @app.call(env) if status == 200 data = JSON.parse(body[0]) data["success"] = true body[0] = data.to_json end [status, headers, body] end end Shrine::UploadEndpoint.use FineUploaderResponse
Unfortunately, this code is not working and infact by using this code fineuploader is throwing following error in console: Error when attempting to parse xhr response text (Unexpected end of JSON input)
Please advice me, how I need to modify this code to insert success property with a valid JSON response. |
| Voice integration in Ruby on Rails App Posted: 18 Aug 2016 04:29 AM PDT I am new to Ruby on Rails as well as programming. I am trying to develop an application which records a voice and authenticate it the next time. I have tried implementing VoiceIt and this recorder. I made some changes in recorder by converting the plain html to erb. this html to <img id="record" src="img/mic128.png" onclick="toggleRecording(this);"> <a id="save" href="#"><img src="img/save.svg"></a>
this erb <%= link_to image_tag("record_audio.png", title: "record", id: "record"), id: "record", :onclick => "toggleRecording(this);" %> <%= link_to image_tag("save_audio.png", title: "save", id: "save"), id: "save" %>
But the recorder is not working. Javascript is not called. Please have a look at the recorder link for complete code. This can see Routing error in server. Started GET "/voiceits/recorder.js" for 192.168.1.102 at 2016-08-18 16:52:59 +0530 Started GET "/voiceits/main.js" for 192.168.1.102 at 2016-08-18 16:52:59 +0530 actionpack (5.0.0.1) lib/action_dispatch/middleware/debug_exceptions.rb:53:in call' Cannot render console from 192.168.1.102!

| Whitespace error on csv file Posted: 18 Aug 2016 03:47 AM PDT task priceupdate: :environment do csvtoopen = open('http://www.someurlhere.com/feed.csv') csv = CSV.foreach(csvtoopen, :headers=>true) csv.each do |row| #Stuff to do with rows here end end
Above is my rake task for the csv file, When i try and run this i get this error CSV::MalformedCSVError: Illegal quoting in line 1.
My work around was this method. csv = CSV.parse(csvtoopen, :headers=>true, quote_char: "\x00")
I'm under the impression it moves things ot a new cell on commas? The issue is i have events coming back with commas. So is there another work around? Heres the csv file http://api.viagogo.net/feeds/ukeventfeed.csv Sam |
