Ruby on Rails - undefined local variable or method - wice grid haml show_code Posted: 03 Aug 2016 07:53 AM PDT I am new to ruby on rails. I am trying to get haml and wice_grid to work together. I am using this example as a model: http://wicegrid.herokuapp.com/basics3 I get the error 'undefined local variable or method `show_code' for...' In the file app/views/basics3/index.html.haml which you can see at the link above. Am I missing a gem? In general, what is the best way to troubleshoot problems like this? Thanks in advance- Flex

Pass rails object value into span title Posted: 03 Aug 2016 07:53 AM PDT I want to be able to pass an object value into the title of a span element however when I use the below code on hover #{campaign.status} is displayed rather than Aprroved or Rejected as is my intention. %td.status-data= campaign.status == "Approved" ?

Submitting a form using jquery doesn't submit it as remote: true rails 4.2 Posted: 03 Aug 2016 07:52 AM PDT I have to submit a form when user clicks a button for that I'm using an onclick JS function call on that button. In that function, I simply submit the form I want using .submit() function. JS function I use, $('#form_id').submit() Also in the form_tag I've used :remote=>true. The HTML method has been changed to post using :method=> "post". Controller also has proper respond_to block with format.js block. View file has proper .js.erb file. But whenever I click the button it is being processed as HTML. If I manually click on that form's submit button it's processed as JS successfully. How to fix the issue??

Rails 4: Stop redirect after create or update form Posted: 03 Aug 2016 07:44 AM PDT Someone know how can I do to Rails do not redirect to other page when I create or update a form? This is because I'm using remote: :true to update the form by ajax. def create @picture = Picture.new(picture_params) respond_to do |format| if @picture.save #format.html { redirect_to @picture, notice: 'Picture was successfully created.' } format.json { render :show, status: :created, location: @picture } else format.html { render :new } #format.json { render json: @picture.errors, status: :unprocessable_entity } end end end <%= form_for(@picture, remote: :remote, :authenticity_token => true, html: { multipart: true } ) do |f| %> [...] <%= f.submit 'Enviar', remote: :true %> If I just remove the redirect function I get the error: ActionController::UnknownFormat Thanks!

Ruby: http POST with nested params not working Posted: 03 Aug 2016 07:47 AM PDT I am trying to do Http Basic Authentication with POST and nested parameters. While the outer parameters work fine (class.name - ActionController::Parameters) the nested parameters are string (class.name - String) Here is my code -> require 'net/http' uri = URI('http://example.com/bulb/') req = Net::HTTP::Post.new(uri) req.basic_auth 'mytest@somesite.com', 'mypassword' req.set_form_data('first_params' => 'a', 'seconnd_params'=>'b', 'netsed_params'=>{'first_netsed'=>'c', 'second_nested'=>'d'}, 'commit'=>'Create Bulb', 'action'=>'create', 'controller'=>'bulb') res = Net::HTTP.start(uri.hostname, uri.port) do |http| http.request(req) end case res when Net::HTTPSuccess, Net::HTTPRedirection # OK else #failed end What other library can I use to make the nested params work without having to manually convert them. I see that set_form_data doesn't work with nested hash

Heroku db:setup returns ECONNREFUSED: connect ECONNREFUSED 50.ipaddress:5000 Posted: 03 Aug 2016 07:23 AM PDT Was making my first rails app and after pushing files to heroku, tried to run the db setup, but it dies with this message: ECONNREFUSED: connect ECONNREFUSED 50.ipaddress:5000 Is it my/server firewall causing this? What can be done? Any kind of help is really appreciated. Here are heroku logs 2016-08-03T14:15:23.910432+00:00 heroku[api]: Starting process with command `bundle exec rake db:setup` by useremail 2016-08-03T14:15:27.606269+00:00 heroku[run.3204]: Awaiting client 2016-08-03T14:15:27.749269+00:00 heroku[run.3204]: State changed from starting to up 2016-08-03T14:15:57.614216+00:00 heroku[run.3204]: Error R13 (Attach error) -> Failed to attach to process 2016-08-03T14:15:57.614216+00:00 heroku[run.3204]: Process exited with status 128 2016-08-03T14:15:57.625775+00:00 heroku[run.3204]: State changed from up to complete

Rails 3: url helper always raise errors in models or console, but work fine in controllers/views Posted: 03 Aug 2016 07:49 AM PDT To be clear, I can call these url_helpers, and what I tried works fine on other projects: it's not an include issue. A simple Rails.application.routes.url_helpers.root_path (or any other route) will throw ActionController::RoutingError: No route matches ... if called from a model, rails console or a view rendered with render_to_string, but the same root will work fine in a controller or view rendered the usual way. Calling a model method using url_helpers from a view or a controller will also raise the same exception, so I don't think it's due to the lack of request. The project is using rails 3.0, and what I tried works fine on other rails 3.0 projects. Would you have any idea where to look to solve this?

GRAPE API + Interactors + current_user Posted: 03 Aug 2016 07:19 AM PDT How to enable 'current_user' in grape controllers? I'm using interactor gem and I'm going to 'create Item' with 'user id' param. I want to associate Item with current_user: item.user_id = current_user.id. How to do that?

How to match multiple patterns with Dir.glob? Posted: 03 Aug 2016 06:54 AM PDT In my Rails app I am trying to collect the paths to all the files contained in two different directories using Dir.glob. The following code works but is not very concise. Isn't there a way two match two patterns at once with Dir.glob? common_file_paths = Dir.glob("app/assets/mystuff/*").reject do |path| File.directory?(path) end more_file_paths = Dir.glob("app/assets/mystuff/more/*").reject do |path| File.directory?(path) end file_paths = common_file_paths + more_file_paths

Rails content_tag method Posted: 03 Aug 2016 07:13 AM PDT I was browsing the source code of this gem and I found a use of content_tag that confuses me a lot. def render(view) view.content_tag(name, attributes[:content], attributes.except(:content)) end I do not understand why content_tag is called on view. I generally use it as helper to generate HTML tags, but I've never called it as a method.

Ruby on Rails adding PDFs to partials Posted: 03 Aug 2016 06:17 AM PDT I have a rails form that a user fills out, and later they can print it off as a PDF. The content is very similar (removed navbar and links, etc). Now I need to add PDF documents at specific locations of the PDF version of the form. For example, take a form for a rental application that has the property details, first tenant details, pdf document, followed by a second tenants details, another pdf document. I'm currently using PDFkit to generate PDFs from html. But I'm open to suggestions. Thanks,

Rails search table clickable link Posted: 03 Aug 2016 07:21 AM PDT I have a keyword search page for which the results are presented in a table. One of the fields in this table is a url which I want to display as a clickable link when the field has one in it but I can't get this working, when the link is clicked it instead queries the search again. I think the problem is due to the def within the searches controller dealing with the keywordsearch view. Can anybody help? Below is the keywordsearch view which contains the results table: <!-- Index of all Courses --> <% provide(:title, "Courses Page") %> <!--Breadcrumbs --> <br> <%= link_to "Back", :back %><br><br> <!--Page Contents --> <div class ="row"> <h1>Degrees Offered</h1> <%= image_tag "line.png" , :alt => "line break"%> </div> <div class ="row"> <!-- Form for Keyword Search, to Querry Database for University courses. It is hidden so as to not appear as a search on the page --> <div class = "hidden"> <%= form_tag(keywordsearch_path, :method => "get", id: "search-data") do %> <%= text_field_tag :search, params[:search], placeholder: "Search course" %> <%= submit_tag "Search" %> <% end %> </div> <% if @search_degree != nil %> <% end %> <% if @search_degree != nil %> <table border="1" class="table"> <thead> <tr> <th>University Name</th> <th>Course Name</th> <th>Duration</th> <th>Qualification</th> <th>Entry Requirements</th> <th>Course Page</th> </tr> </thead> <tbody> <% @search_degree.each do |degree| %> <tr> <td><%= degree.uname %></td> <td><%= degree.cname %></td> <td><%= degree.duration %></td> <td><%= degree.qualification %></td> <td><%= degree.entry %></td> <td> <a href=<% degree.url %>>View course page on University Website</a></td> </tr> <% end %> </tbody> </table> <% end %> </div> Below is portion of the search controller in which keyword search is defined: def keywordsearch @search = Degree.all.select(:uname, :cname, :ucas, :duration, :qualification, :entry).distinct.order(id: :ASC) if params[:search] @search_degree = Degree.search(params[:search]).order('uname ASC') end end The link from all of this is clickable but rather than taking me to the correct url it redoes the search.

logrotate appending the date to logs in wrong way Posted: 03 Aug 2016 05:58 AM PDT I have a rails application and I have setup logrotate for the logs. The logs are like production.log, sidekiq.log, cron.log in the directory /home/username/myapp/log/. I want the rotated logs should be named like production.log-server-1-2016-08-02-1470119678.gz. This type of file is also present but one more file is there which is named like production.log-server-1-2016-08-02-1470119678.gz-server-1-2016-08-03-1470206339-server-1-2016-08-03-1470225672.gz.

TinyTDS: Server name not found in configuration files Posted: 03 Aug 2016 07:48 AM PDT I keep seeing this error, and I am unable to connect to the database on the remote server. I am given a connection string to the database, that looks like the following: data source=qsss.gar.de\SQL2012,3000;initial catalog=City;persist security info=True;user id=user_me;password=user_me##2009; Now, I have created a database.yml file based on that connection string, like the following: development: adapter: 'sqlserver' host: 'qsss.gar.de\SQL2012,3000' port: 1433 database: 'City' username: 'user_me' password: 'user_me##2009' And as I try and run the server, it always hits me with the Server name not found in configuration files error. opts[:port] ||= 1433 opts[:dataserver] = "#{opts[:host]}:#{opts[:port]}" if opts[:dataserver].to_s.empty? connect(opts) // ERROR AT THIS LINE end def tds_73? Please try and help me figure what is the problem with this? UPDATE: I can connect to the server using SQLPro for MSSQL wizard, with exactly the same connection parameters: picture It works from the wizard, but not from code using TinyTDS!

What does yield do in this Ruby method? Posted: 03 Aug 2016 05:52 AM PDT I have a bit of old code in a legacy app which uses yield in a way that I don't understand. I could use some help with an explanation. I've read most of the SO results on Ruby yield but don't understand it in this context. Thanks. def find_all_from_source(source_id, some_more_arguments) joins, conditions = invoke_records_from_source(source_id, some_more_arguments) find(:all, :select => "#{self.table_name}", :joins => joins, :conditions => conditions).each do |record| yield record end end model.find_all_from_source(source_id, some_more_arguments)

Twilio Say when putting conference on hold Posted: 03 Aug 2016 05:47 AM PDT I am able to put the conference call on hold, but I would like Twilio to say something like 'This call has been put on hold' to all participants before the music starts playing.

spaghetti code - how to fix my db calls Posted: 03 Aug 2016 05:16 AM PDT My db calls are like this: orders_pending_acceptance = Order.joins(:notifications).includes(:timestamps) .where(shopper_status: 'shopper_pending_acceptance') .where("notifications.created_at > ?", now - 10.minutes) .select { |order| order.time_calculator .latest_shopper_assignment_time < order.timestamps .where(name: 'shopper_pending_acceptance').value } and it looks ugly, not speaking about hound issues. How to fix it? Could you please suggest different approach?

Ruby Mysql2 Client not taking backslash while insert Posted: 03 Aug 2016 07:27 AM PDT We are using production and staging databases in our application. Our requirement is to insert all the records to staging database when ever a record is added in production database, so that both the servers are consistent and same data. I have used Mysql2 client pool to connect to staging server and insert the record that is added to production. here is my code: def create @aperson = Person.new @person = @aperson.save if @person && Rails.env == "production" #add_new_person_to_staging client = Mysql2::Client.new(:host => dbconfig[:host], :username => dbconfig[:username], :password => dbconfig[:password], :database => dbconfig[:database]) @person_result = client.query('INSERT INTO user_types(user_name, regex, code) Values ("myname" , "\.myregex\." , "ns" );') end end Here "@person_result" record is inserted to mysql table but the "regex" column eliminates "\" slashes. like : user_name = myname, regex = .myregex., code = ns when I manually execute the "Insert" query in mysql command line it inserts as it is along with \ slash. but not through "client.query" Why does \ slash is eliminated. please help me here. Thanks.

Rails query execution causes database spikes Posted: 03 Aug 2016 05:05 AM PDT I'm having a problem with my Rails application where some random queries take around 5 seconds or longer to finish. Most of the time the queries are very simple (select * from x where id = ?) and the fields are even indexed too. Here's some more information about the setup: Puma 3.5.0 behind a reversed nginx proxy 4 workers with minimum 4, max 8 threads each. Ruby v2.2.3, Rails v4.2.4 PostgreSQL 9.4 database Thread pool set to max 60 connections Appsignal for monitoring 8GB RAM, 4 CPU's, SSD. I found this out when looking at the query performance in Appsignal. I noticed most queries finishing in a few ms and then every now and then, still in the same request, there are multiple queries that take 5+ seconds to finish. And the odd part is that it ALWAYS takes 5,.. seconds. Here's a picture of that in action: Things I've tried: Increase the thread pool to make sure the puma worker threads have enough connection objects. Set 'reaping_frequency' to 10s to make sure there are no dead connections being used. Increase puma workers/threads I'm noticing this in the application as there are some pages that take a long time to load (I have a function call that takes about 1 minute to finish) and somehow this is blocking new requests. This is strange to me as there are 4 workers each with 8 threads = 32 threads that can handle the other requests.

Multiple addresses in rails geocoder issue Posted: 03 Aug 2016 06:40 AM PDT I have a booking model with location_pickup and location_dropoff on which i want to use the geocoder feature.

OpenSSL::SSL::SSLError hostname does not match the server certificate rails 2 Posted: 03 Aug 2016 04:41 AM PDT I'm trying to make an API call to SmartDebit a 3rd party direct debit processing website from my Ruby 1.9.3, Rails 2 app. I'm getting this error: OpenSSL::SSL::SSLError·hostname does not match the server certificate The error occurs here: "https://onepointnine.survivalinternational.org/donate" when trying to make a direct debit payment. As far as I can tell my SSL certificate is correctly set up and valid for this hostname, Smart Debit have confirmed that the error doesn't refer to their endpoint. Also, the error can't be to do with certificate verification because I already have this code in an initializer (n.b. I realise this isn't best practice, I've inherited this codebase): class Net::HTTP alias_method :old_initialize, :initialize def initialize(*args) old_initialize(*args) @ssl_context = OpenSSL::SSL::SSLContext.new @ssl_context.verify_mode = OpenSSL::SSL::VERIFY_NONE end end Any idea what's wrong?

Sidekiq monitoring and devise are mounted in routes as follows: devise_for :users, skip: [:sessions] as :user do get 'login' => 'devise/sessions#new', :as => :new_user_session post 'login' => 'devise/sessions#create', :as => :user_session delete 'logout' => 'devise/sessions#destroy', :as => :destroy_user_session end require 'sidekiq/web' require 'sidekiq/cron/web' #Sidekiq::Web.set :session_secret, Rails.application.secrets[:secret_key_base] authenticate :user do mount Sidekiq::Web => '/sidekiq' end But, accessing the sidekiq status page logs out the user. The same code used to work fine with Rails 4.2.5

Route to Current User Edit in a view Posted: 03 Aug 2016 05:45 AM PDT What is the syntext I need to use in order to route to edit the current user's profile? I want to put a link on my page that takes you to edit your user profile. I know how to link_to but not sure what what the syntex is to get to the current user. My Users controller looks like this: class UsersController < ApplicationController before_action :logged_in_user, only: [:index, :edit, :update, :destroy] before_action :correct_user, only: [:edit, :update] before_action :admin_user, only: :destroy def index @users = User.paginate(page: params[:page]) end def new @user = User.new end def create @user = User.new(user_params) if @user.save flash[:notice] = "Welcome to Studio Academy Manager" sign_in @user redirect_to root_url else render 'new' end end def show @user = User.find(params[:id]) end def edit @user = User.find(params[:id]) end def update @user = User.find(params[:id]) if @user.update_attributes(user_params) flash[:success] = "Profile updated" redirect_to @user else render 'edit' end end def destroy User.find(params[:id]).destroy flash[:success] = "User deleted" redirect_to users_url end private def user_params params.require(:user).permit(:email, :username, :password, :password_confirmation, :first_name, :last_name, :phone, :street_1, :street_2, :city, :state, :zip, :enabled, :admin) end def logged_in_user unless current_user.present? store_location flash[:danger] = "Please log in." redirect_to login_url end end def correct_user @user = User.find(params[:id]) redirect_to(root_url) unless @user == current_user end def admin_user redirect_to(root_url) unless current_user.admin? end end And In my routes file I have: resources :users

Prawn Rails, generate table with some content not bound by table Posted: 03 Aug 2016 04:14 AM PDT I am trying to build a fairly complex pdf using Prawn in Rails. The document I am trying to generate is a form of script split into four columns. The script is comprised of a collection of 'snippets', which are iterated through and populate the third column. If a snippet has special properties it can also populate any one of the other three columns as well. This is all achieved very easily using tables. However, I then need to be able to draw an arrow of some description (using prawn graphics) at certain points spanning between the table columns (please see attached image). How is this achieved since content is bound by table cells? Is there a way to later draw these lines using cursor points or some other method? Please ask for further for clarification if I'm not making any sense. Thanks
