| Duplicate delete links Posted: 20 Dec 2016 08:17 AM PST On a user's profile page, a user can create posts. I've recently added a delete link for users to delete their posts. The problem however, each individual post is showing all delete links for all posts. Example: So if Jimmy has 3 posts, each post will have 3 delete links Here's my code: posts_controller.rb class PostsController < ApplicationController def index @posts = Post.allow end def new @post = Post.new end def create @post = Post.new(post_params) @post.user_id = current_user.id # assign the post to the user who created it. respond_to do |f| if (@post.save) f.html { redirect_to "", notice: "Post created!" } else f.html { redirect_to "", notice: "Error: Post Not Saved." } end end end def destroy # users can delete their own posts @post = Post.find(params[:id]) if current_user == @post.user @post.destroy end redirect_to root_path end private def post_params # allows certain data to be passed via form. params.require(:post).permit(:user_id, :content) end end
pages_controller.rb class PagesController < ApplicationController def index end def home @posts = Post.all @newPost = Post.new end def profile # grab the username from the URL as :id if (User.find_by_username(params[:id])) @username = params[:id] else # redirect to 404 (root for now) redirect_to root_path, :notice=> "User not found" end @posts = Post.all.where("user_id = ?", User.find_by_username(params[:id]).id) @newPost = Post.new @users = User.all end def explore @posts = Post.all end end

| Rails Arels: Unsupported argument type: String. Construct an Arel node instead Posted: 20 Dec 2016 07:57 AM PST I'm using Arels for creating query. In this query, I use generate_series function. Here is my code: def generate_series Arel::Nodes::NamedFunction.new('GENERATE_SERIES', [start_date, end_day, '1 day']) end def start_date Arel::Nodes::SqlLiteral.new(<<-SQL CASE WHEN DATE_PART('hour', NOW() AT TIME ZONE 'ICT') < #{Time.now - 3days} THEN (CURRENT_DATE - INTERVAL '14 days') ELSE (CURRENT_DATE - INTERVAL '13 days') END SQL ) end def end_date Arel::Nodes::SqlLiteral.new(<<-SQL CASE WHEN DATE_PART('hour', NOW() AT TIME ZONE 'ICT') < #{Time.now} THEN (CURRENT_DATE - INTERVAL '1 day') ELSE CURRENT_DATE END SQL ) end
When I try to test by generate_series.to_sql. I meet exception: Arel::Visitors::UnsupportedVisitError: Unsupported argument type: String. Construct an Arel node instead. I try to shorter my code for testing: def generate_series Arel::Nodes::NamedFunction.new('GENERATE_SERIES', ['19/11/2012', '20/11/2012', '1 day']) end
The problem is same. Please tell me how can I fix this problem. |
| The association `has_and_belongs_to_many` has an option 'uniq'? Posted: 20 Dec 2016 07:49 AM PST I am learning rails with the book 'Rails 4 in Action', and it says the association has_and_belongs_to_many has an option uniq. But it seems it doesn't work as it says. The class below means only unique tags should be retrieved for each ticket, but all the duplicate tags are getting retrieved unlike the book says. class Ticket < ActiveRecord::Base ... has_and_belongs_to_many :tags, uniq: true ...
I now doubt if the association has_and_belongs_to_many has an option uniq. I guess it doesn't have, and I checked this in the active record association document. http://guides.rubyonrails.org/association_basics.html |

| has_many of itself though Posted: 20 Dec 2016 06:57 AM PST I'm working on a maze project in rails, and ironically, I got lost. So far, I'm pretty new with has_many_though relationships between models, so what if a model has many of itself through something ? Basically, Each Room has many Rooms. I created a Tunnel model to connect these rooms, so that a room is connected to many others through tunnels. But it gets trickier when it comes to building these relations. class Room < ApplicationRecord has_many :tunnels has_many :rooms, through: :tunnels end
And my Tunnel gets to connect two rooms class Tunnel < ApplicationRecord belongs_to :lemmin_room, :foreign_key => "room1_id" belongs_to :lemmin_room, :foreign_key => "room2_id" end
Rails documentation is pretty clear when it comes toe ModelA has many Model B through ModelC, but I don't think it ever mentions ModelA = ModelB. |
| Pattern to render multiple coffee Posted: 20 Dec 2016 07:07 AM PST I have a task model which is related to the user and project models. When I create/update a task, I need to do an update in the view async, not only for the task change/addition, but to the project and user info (because some of that data might change too). I have this in the controller: def create @task = Task.new(params[:task]) @project = Project.find(params[:project_id]) respond_to do |format| if @task.save format.html { redirect_to @task, notice: 'Task was successfully created.' } format.json { render json: @task, status: :created, location: @task } else format.html { render action: "new" } format.json { render json: @task.errors, status: :unprocessable_entity } end end end
And my tasks/create.js.coffee # Update task table $('#mytable').append("<%= j render(partial: 'tasks/task', locals: { t: @task }) %>") # Update user data $('.user-data').html("<%= j render(partial: 'users/user_widget', locals: { u: current_user }) %>") # Update project data $('.project-data').html("<%= j render(partial: 'projects/project_widget', locals: { p: @project }) %>")
And it works great. I see 2 issues: In every render of .js.coffee I add, I am repeating the code too much. I duplicate exactly the same code for updating project and user data, on tasks update, tasks destroy, and I would do the same for a new model which might affect the user and the project It seems weird to handle project and user data in tasks/create.js.coffee Therefore, I am looking for a better pattern to handle this stuff, any ideas? EDIT (to clarify): I think achieving something like this would be better: tasks/create.js.coffee # Update task table $('#mytable').append("<%= j render(partial: 'tasks/task', locals: { t: @task }) %>") UserData.refresh() ProjectData.refresh()
However, I can't do that because I need to render the partial each time, so I would have to do something weird like passing the html partial to those refresh() functions, and it would be pretty the same as the previous way. This is just a way that came to my mind, but I would like to hear your ideas if any. |

| How to handle 'Unclosed quotation mark after the character string' in Ruby? Posted: 20 Dec 2016 08:12 AM PST I'm getting an error when trying to grab html from a webpage and saving it to my active record object. The message I'm getting is, Unclosed quotation mark after the character string. Is there a function in Ruby or a way to go about checking and then correcting instances where this happens prior to saving the record to the database? The full error from TinyTDS is below... ActiveRecord::StatementInvalid: TinyTds::Error: Unclosed quotation mark after the character string '
Update My apologies, didn't realize I hadn't added enough information. I'll happily add any requests. Let me start with the log, and also to the part about "escaping my data" correctly -- It's HTML from an outside source that's throwing the error. So to that point I guess perhaps I go back to my initial question which was how do I go about locating where the unclosed quotation mark is, and then correcting it?

| Ruby replace only part of the Matching String Posted: 20 Dec 2016 07:16 AM PST How do I replace only part of the String in a Ruby code? Supposed I have a text file that contains multiple occurrences of the keyword "JVM_MEM_ARGS_64BIT" JVM_MEM_ARGS_64BIT="-Xms512m -Xmx512m"
and I only want to replace the first occurrence, I can use the #sub instead of gsub a.sub('JVM_MEM_ARGS_64BIT="-Xms512m -Xmx512m"', 'JVM_MEM_ARGS_64BIT="-Xms512m -Xmx1024m"')
however not all files contains JVM_MEM_ARGS_64BIT="-Xms512m -Xmx512m"
some could be JVM_MEM_ARGS_64BIT="-Xms256m -Xmx512m"
I am not sure how to do this in a ruby code? I can search for the keyword "JVM_MEM_ARGS_64BIT" only but how do I delete the existing value assignment and replace it with JVM_MEM_ARGS_64BIT="-Xms512m -Xmx1024m Newbie Ruby developer. |

| Can't connect to PostgreSQL with Rails and Capistrano Posted: 20 Dec 2016 06:17 AM PST I'm trying to deploy my Rails 5 application using Postgres to a VPS via Capistrano. It keeps failing, though - giving me a PG::ConnectionBad: FATAL: password authentication failed for user 'sys_user'. The relevant settings of my database.yml are: production: <<: *default database: <%= ENV['RDS_DB_NAME'] %> username: <%= ENV['RDS_USERNAME'] %> password: <%= ENV['RDS_PASSWORD'] %> host: <%= ENV['RDS_HOSTNAME'] %> port: <%= ENV['RDS_PORT'] %>
All these environment variables have been set in /etc/environment - this is definitely the case because it's picking up the RDS_USERNAME as sys_user. The password of the database is the same as the variable RDS_PASSWORD. The port, hostname etc. are all the same also. I'm stumped. Please help. |

| vagrant error, not start global-status Posted: 20 Dec 2016 06:07 AM PST I've got this error when I tried to do the command vagrant global-status on my server: Vagrant experienced a version conflict with some installed plugins! This usually happens if you recently upgraded Vagrant. As part of the upgrade process, some existing plugins are no longer compatible with this version of Vagrant. The recommended way to fix this is to remove your existing plugins and reinstall them one-by-one. To remove all plugins: rm -r ~/.vagrant.d/plugins.json ~/.vagrant.d/gems Note if you have an alternate VAGRANT_HOME environmental variable set, the folders above will be in that directory rather than your user's home directory. The error message is shown below: Bundler could not find compatible versions for gem "bundler": In Gemfile: vagrant (= 1.8.5) was resolved to 1.8.5, which depends on bundler (~> 1.12.5) Current Bundler version: bundler (1.13.6) This Gemfile requires a different version of Bundler. Perhaps you need to update Bundler by running `gem install bundler`? Could not find gem 'bundler (~> 1.12.5)', which is required by gem 'vagrant (= 1.8.5)', in any of the sources.

I tried something like this but doesn't work: test_array.each do |testArray| test_array.sub('and drinks', '') end => ["we serve foo and drinks", "we serve toasts and drinks", "we serve kale and drinks"]

| How to validate a field with jQuery Validation in rails Posted: 20 Dec 2016 06:25 AM PST I followed this tutorial to validate a form in rails with the jquery validation plugin: https://sleekd.com/tutorials/jquery-validation-in-ruby-on-rails/ The validations work me correctly except when I have to validate a single field, in the tutorial explain how to validate an email, but I have already tried everything, someone who can help me please thank you This is an example: $(document).ready(function () { $("#new_user").validate({ debug: true, rules: { "user[email]": {required: true, email: true, remote:"/users/check_email" }, "user[password]": {required: true, minlength: 6}, "user[password_confirmation]": {required: true, equalTo: "#user_password"} } }); });
in controller def check_email @user = User.find_by_email(params[:user][:email]) respond_to do |format| format.json { render :json => !@user } end end
in routes.rb: map.check_email "users/check_email", :controller => "users", :action => "check_email" map.resources :users

| custom sign in form for devise not working Posted: 20 Dec 2016 05:05 AM PST I am currently trying to create a custom sign in form for users created by devise. When the sign-in form is submitted i get an error saying invalid email or password even though the details are correct. I am using ajax to render the forms from partials so could be the thing causing some trouble but i am not sure. here is the form <span id="close-button" class="glyphicon glyphicon-remove pull-right"></span> <%= form_tag(new_user_session_path, method: :post) do %> <div class="form-group"> <%= label_tag :email %> <%= email_field_tag :email, nil, :class => "form-control" %> </div> <div class="form-group"> <%= label_tag :password %> <%= password_field_tag :password, nil, :class => "form-control" %> </div> <%= submit_tag "Sign In", class: "btn btn-primary" %> <% end %> <script> $('#close-button').on('click', function() { $(this).parent().html(" "); }); </script>
here is my routes file Rails.application.routes.draw do devise_for :users, controllers: { registrations: 'users/registrations', sessions: 'users/sessions' } # For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html root 'pages#index' devise_scope :user do get '/sign_up_form' => 'users/registrations#sign_up_form', as: 'user_sign_up' get '/sign_in_form' => 'users/sessions#sign_in_form', as: 'user_sign_in' end end
and here is my controller class Users::SessionsController < Devise::SessionsController def sign_in_form end end
I also have a .js.erb file for rendering the form, everything is working fine displayig the form it is just when it is submitted it doesnt do what i intended. Thanks in advance to anyone who can help me solve this problem. |
| ajax will_paginate drops the page to first when browser page refresh Posted: 20 Dec 2016 05:45 AM PST I'm beginner in RoR and I have app in which I use ajax with will_paginate like in #174 Pagination with AJAX - RailsCasts. All working fine, but I have issue such as after I select any will_paginate page and then refresh browser page will_paginate drops the page to '1'. I can't think that it is necessary to make that in case of refreshing of the browser page the will_paginate page still remained page selected early. Some my code: _index_table.html.erb <%= will_paginate @outdoor_advertisings, :param_name => 'order_page' %> <table class="index_table"> ... </table> <%= will_paginate @outdoor_advertisings, :param_name => 'order_page' %>
index.html.erb <div id="index_table"> <%= render 'index_table' %> </div>
index.js.erb $("div#index_table").html("<%= escape_javascript(render("index_table")) %>"); $(".ajax-progress").hide();
controller action class OutdoorAdvertisingsController < ApplicationController def index if !params[:order_page].present? params[:order_page] = '1' end @outdoor_advertisings = OutdoorAdvertising.where(active: true) .paginate(page: params[:order_page], per_page: 30) respond_to do |format| format.html format.js end end end
outdoor_advertisings.js.coffee $("body").on "click", "div#index_table .pagination a", -> $(".ajax-progress").show(); $.getScript @href return false
server console log when index page open first time Started GET "/outdoor_advertisings" for 127.0.0.1 at 2016-12-20 16:36:09 +0200 Processing by OutdoorAdvertisingsController#index as HTML

| Rake task not sending mail rails Posted: 20 Dec 2016 05:44 AM PST I've written my first rake task in rails, I've set it up with the Heroku scheduler and it is getting run, however the mail isn't getting sent. My mail settings are fine as I'm using it for various other things, I would imagine it's a problem with my code in the rake task. Any help would be much appreciated. lib/tasks/uncomplete_form.rake desc "Remind users if they haven't completed quote form" task uncomplete_form: :environment do puts 'Reminding users of uncomplete quote form' date = Date.parse('december 18 2016') quickcontacts = Quickcontact.where(created_at: date.midnight..Time.now) quickcontacts.each do |quickcontact| next unless quickcontact.created_at > 1.hour.ago if quickcontact.p_p = nil QuickcontactMailer.uncomplete_form(@quickcontact).deliver end end puts 'done.' end
By running rake uncomplete_form I get Reminding users of uncomplete quote form done. And running heroku run rake uncomplete_form I get Reminding users of uncomplete quote form Quickcontact Load (1.5ms) SELECT "quickcontacts".* FROM "quickcontacts" WHERE ("quickcontacts"."created_at" BETWEEN '2016-12-18 00:00:00.000000' AND '2016-12-20 12:09:23.683977') done.
It doesn't seem to be picking up any quickcontacts - however if in the console I run: date = Date.parse('december 18 2016')
followed by quickcontacts = Quickcontact.where(created_at: date.midnight..Time.now)
It does find the expected contacts |
| Ruby on Rails - Count Entries on Scaffold Posted: 20 Dec 2016 04:41 AM PST In a simple Ruby on Rails applicaiton, I have a Scaffold called "Proposals" on which one of its columns is a string called "creationyear". I'm trying to count how many proposals have been created each year when the index page is loaded doing the following (in "proposals_controller.rb" file): def index @proposals = Proposal.all @count2015 = Proposal.count(:all, :conditions => "creationyear = 2015") @count2016 = Proposal.count(:all, :conditions => "creationyear = 2016") end
Somehow it is not working, since it gives me back on both variables the total number of entries on the scaffold. Does anyone knows how to solve this one? I'm using Rails v4.2.6. Thanks! |
| Rails commands not working on raspberry pi though it is installed Posted: 20 Dec 2016 04:21 AM PST I've been setting up a server on my Raspberry Pi but for some reason when I SSH into the pi I can use the rails commands and start the Rails server but whenever I go into the terminal of the Pi itself it says: bash: rails: command not found
Does someone know how to fix this? How can I make the rails command possible on the Pi terminal? Thanks in advance! |
