Case insensitive search using IN operator in Ruby on Rails and PostgreSQL Posted: 20 May 2016 06:58 AM PDT I'm new to ROR and trying to implement search in PostgreSQL database using Active Record. I've found that to make search case insensitive I can use ILIKE operator instead of equals and LIKE but not sure what to do when I need to use IN operator. I'm getting field name and collection of values which I need to check and case sensitive search works like that records = records.where(filter['fieldName'] => filter['value']) where filter['value'] is an array. Is there a way to update that line to make it case insensitive? If no then I believe the only way is to loop through that array and split IN into many OR operations and use ILIKE for every single value in that array(however I'm not sure how use OR with Active Record)? Thanks!

Rails Activerecord, Nested Validations Posted: 20 May 2016 06:55 AM PDT I've been worrying this bug for too many days and I'm not sure what I'm missing. I have a parent model named 'product' and a child of it 'product_attachment' Validation within child model is successful on create to disallow a blank image field via /product_attachments#new However, when using it through its parent form (files below) when I expect it to fail, Activerecord is ignoring the error, and my controller is complaining that it is blank. I'm currently in the understanding that using the 'validates_associated' would validate the child model as part of the Parent's process but this has not been working. Instead of passing a happy failed validation mid-form to allow user to take action, we leave form and the controller tries to process the create method which fails due to no attachment. Since I should always have an attachment have been trying to fix this validation to no avail. Any help appreciated, I've include similar code samples before for your feedback. I'm fairly new to rails so I'm hoping I'm mis-using a key syntax or context. Also curious what cause is and what best way was to troubleshoot as I'm still developing good debug practices. product.rb class Product < ActiveRecord::Base has_many :product_attachments validates_presence_of :title, :message => "You must provide a name for this product." accepts_nested_attributes_for :product_attachments, allow_destroy: true#, validates_associated :product_attachments end product_attachment.rb (carrierwave to handle uploading used here, seems to work fine) class ProductAttachment < ActiveRecord::Base belongs_to :product mount_uploader :image, ImageUploader validates_presence_of :image, :message => "You must upload an image to go with this item." end products_controller.rb class ProductsController < ApplicationController before_action :set_product, only: [:show, :edit, :update, :destroy] def index @products = Product.all end def show @product_attachments = @product.product_attachments.all end def new @product = Product.new @product_attachment = @product.product_attachments.build end def edit end def create @product = Product.new(product_params) respond_to do |format| if @product.save params[:product_attachments]['image'].each do |a| @product_attachment = @product.product_attachments.create!(:image => a) end format.html { redirect_to @product, notice: 'Product was successfully created.' } else #- when would this fire? format.html { render :new } end end end def update respond_to do |format| if @product.update(product_params) params[:product_attachments]['image'].each do |a| @product_attachment = @product.product_attachments.create!(:image => a, :post_id => @post.id) end format.html { redirect_to @product, notice: 'Product was successfully updated.' } else #- when would this fire? format.html { render action: 'new' } end end end def destroy @product.destroy respond_to do |format| format.html { redirect_to @product, notice: 'Product was successfully destroyed.' } end end private def set_product @product = Product.find(params[:id]) end # we pass the _destroy so the above model has the access to delete def product_params params.require(:product).permit(:id, :title, :price, :barcode, :description, product_attachment_attributes: [:id, :product_id, :image, :filename, :image_cache, :_destroy]) end end product_attachments_controller.rb class ProductAttachmentsController < ApplicationController before_action :set_product_attachment, only: [:show, :edit, :update, :destroy] def index @product_attachments = ProductAttachment.all end def show end def new @product_attachment = ProductAttachment.new end def edit end def create @product_attachment = ProductAttachment.new(product_attachment_params) respond_to do |format| if @product_attachment.save @product_attachment.image = params[:image] format.html { redirect_to @product_attachment, notice: 'Product attachment was successfully created.' } else format.html { render :new } end end end def update respond_to do |format| if @product_attachment.update(product_attachment_params) @product_attachment.image = params[:image] format.html { redirect_to @product_attachment.product, notice: 'Product attachment was successfully updated.' } else format.html { render :edit } end end end def destroy @product_attachment.destroy respond_to do |format| format.html { redirect_to product_attachments_url, notice: 'Product attachment was successfully destroyed.' } end end private # Use callbacks to share common setup or constraints between actions. def set_product_attachment @product_attachment = ProductAttachment.find(params[:id]) end def product_attachment_params params.require(:product_attachment).permit(:id, :product_id, :image, :image_cache) end end _form.html.slim (using simple_form + slim + cocoon here...) = simple_form_for @product do |f| - if @product.errors.any? #error_explanation h2 = pluralize(@product.errors.count, "error") | prohibited this product from being saved: ul - @product.errors.each do |attribute, message| - if message.is_a?(String) li= message = f.input :title = f.input :price, required: true = f.input :barcode = f.input :description h3 attach product images #product_attachment = f.simple_fields_for :product_attachments do |product_attachment| = render 'product_attachment_fields', f: product_attachment .links = link_to_add_association 'add product attachment', f, :product_attachments = f.submit _product_attachment_fields.html.slim Noted I needed to name my file field this way for my controller to use files correctly, but unsure why still. .nested-fieldsLet me know if I can provide anything else and Thanks again. = f.file_field :image , :multiple => true , name: "product_attachments[image][]" = link_to_remove_association "remove", f Let me know if I can provide anything else. Thank you for your time to read/reply. Edit1: My current method to debug I'm working through as of writing this is to strip out code chunks and test functionality by through browser. I've read I should be more familiar with rails console but have not got there yet.

RAILS: Don't create new record if exists Posted: 20 May 2016 06:29 AM PDT Basically what i need is just method (probably before_create filter) performed when creating new record to check if record with such a title exists (case insensitive) and if it is exists - return finded record and don't create new. If not - create new record. It is NOT simple exists? check. I have nested form with 9 association. I need method that would be executed before creating record and preform action like i described in topic, so i can reffer that action to each of associated model Thank you.

Add quality method to refile-imagemagick Posted: 20 May 2016 06:13 AM PDT I'm trying to add a quality optimizing method to refile-imagemagick based on this questions/answer: Optimise/compress images uploaded with refile However how do i do this? I have tried adding this file to lib: lib/refile_optimize.rb module Refile class MiniMagick def quality(percentage) manipulate! do |img| unless img.quality == percentage img.write(current_path) do self.quality = percentage end end img = yield(img) if block_given? img end end end end And require it in environment.rb: # Load the Rails application. require File.expand_path('../application', __FILE__) require 'refile_optimize' # Initialize the Rails application. Rails.application.initialize! I might be completely off with my approach here, so please feel free to suggest a different solution. I wan tot be able to get an image that fills 1920x1080 and is reduced in filesize through the refile helper like so: <%= attachment_url(@cover, :thumbnail, :fill, 1920, 1080 **missing_something?**) %>

Rails 3 best_in_place_if how to add "id" attribute to element Posted: 20 May 2016 05:53 AM PDT I am using best_in_place_if for inline editing. Here I want to catch the id of current element edited by using the ajax success event of best_in_place. Below is code snippet I am trying to add id attribute. But when I inspect the html, the value for id attribute is the default value generated by the bes_in_place. As per their doc, its mentioned that the default value can be changed by providing our own value. The default value for id attribute is shown as id="best_in_place_trip_32_is_active" and I want is only id=32 best_in_place_if(current_user.admin,trip,:is_active, :type => :checkbox, :classes => 'trip_disable', :id => trip.id) Please let me know what I am missing.

rails4 scoped has_many association Posted: 20 May 2016 06:42 AM PDT In my product_users joint table there is a role column besides the product_id and user_id. I have this association in my product model. has_many :owners, -> { where(product_users: { role: "owner" }) }, through: :product_users, source: :user All of the products will have only one "owner" and the rest will be "member". What association should I use to to get the owner of the product instead of an owners collection. So in the views I wanna use product.owner. I couldn't figure out how to use either has_one or belongs_to. I could use this instance method, but I guess it would be better to define a fine association somehow. def owner owners.first end

How to perform single sql query to sum columns from grouped results in activerecord? Posted: 20 May 2016 06:44 AM PDT I have two models - Parent and Params, where parent has_many params Currently, my methods looks like: def total_sum params.select( 'params.*, ( SUM(mono_volume_annular) + SUM(day_volume_annular) + SUM(night_volume_annular) + SUM(exclusive_volume_annular) ) AS summed_volume_annular' ).group('params.id').sum(&:summed_volume_annular) end How can I improve this SQL query to get rid of .sum(&:summed_volume_annular) method call?

Is ActiveRecord changing the encoding on my serialized hash Posted: 20 May 2016 05:15 AM PDT I have a Rails application which accepts JSON data from third-party sources, and I believe I am running up against some ActiveRecord behind-the-scenes magic which is recognizing ASCII-8BIT characters in hashes extracted from the JSON and saving them as such to my database no matter what I do. Here is a simplified description the class ... class MyClass < ActiveRecord::Base serialize :data end and of how an object is created ... a = MyClass.new a.data = { "a" => { "b" => "bb", "c" => "GIF89a\x01\x00\x01\x00\x00\x00\x00\x00!\vNETSCAPE2.0\x03\x01\x00\x00!\x04\t\x00\x00\x01\x00,\x00\x00\x00\x01\x00\x01\x00\x00\x02\x02L\x01\x00;" } } I believe those are ASCII-8BIT characters, so fair enough if they are saved as such (despite my attempts to UTF8 everything everywhere). But I need these characters to be UTF-8, because when I go to view them I get: ActionView::Template::Error ("\xEF" from ASCII-8BIT to UTF-8): 64: <div> 65: <pre><%= mc.prettify %></pre> 66: </div> app/models/my_class.rb:28:in `prettify' where line #28 in prettify is: JSON.pretty_generate(self.data) So I sought to re-encode any string in the Hash. I built out functionality to do this (with anonymous classes and refinements to Hash, Array and String), but no matter what, ASCII-8BIT is returned to me. In the simplest terms here is what is happening: mc = MyClass.find(123) mc.data['a']['c'].encode!(Encoding.find('UTF-8'), {invalid: :replace, undef: :replace, replace: ''}) mc.data['a']['c'].encoding #=> #<Encoding:UTF-8> mc.data['a']['c'].valid_encoding? #=> true mc.save! mc.reload mc.data['a']['c'].encoding #=> #<Encoding:ASCII-8BIT> <-- !!!!! What is ActiveRecord doing to this hash when it saves it? And what can I do to store a hash permanently with all strings encoded to UTF-8 in a serialized MySQL (v5.6, via the mysql2 gem) mediumtext column (using Ruby 2.2.4 and Rails 4.1.4)?

Make a current Image Uploader to upload multiple images Posted: 20 May 2016 06:23 AM PDT I want to make a change on my current model to be able to upload more than one picture. Currently, only one allowed. I have searched stackoverflow but it only shows how I can install carrierwave and make a model to upload multiple picutres FROM SCRATCH. Here, I want to change my current model, so differently. I will show you what my model look like now. properties.html.erb <span class="thumb"><a href="#"><img src="<%=p.image.thumb.url %>"></a></span> property.rb class Property < ActiveRecord::Base belongs_to :admin mount_uploader :image, ImageUploader end db -> add_image_to_property.rb class AddImageToProperty < ActiveRecord::Migration def change add_column :properties, :image, :string end end Hope I could find a detailed explanation.

will_paginate for search result? Posted: 20 May 2016 04:41 AM PDT I am using will_paginate gem for the pagination on my application. I have created a search action with the following code. Controller def index @transactions = Transaction.all.paginate(:page => params[:page], :per_page => 10) end def search @transactions = Transaction.paginate(:page => params[:page], :per_page => 10).where(:created_at => params[:from_date].to_datetime..(params[:to_date].to_datetime + 1.day)) end search.js.erb $("#searchResult").replaceWith('<div id = "searchResult"><%=j render 'result' %></div>'); _result.thml.erb <div> <%= @transactions.each do |f| %> ...... ...... <% end %> </div> <%= will_paginate @transactions %> index.html.erb <div id = "searchResult"> <%= render = "result"%> <% end %> pagination.js $(function() { $(".pagination a").on('click', function(){ $(".pagination").html("Page is loading..."); $.getScript(this.href); return false; }); }); It somehow works for a index action, ajax method works for the links but when the I click on the last or the first page links generates like localhost:3000/control?_=1463743428904&page=1 also, when ever I hit the search, the pagination links throws link like localhost:3000/control/search?from_date=2016-05-18&page=2&to_date=2016-05-20&utf8=%E2%9C%93 which should be like localhost:3000/control?page=1. Is there any solution for this.

Rails - Split integer form field into 3 separate sections Posted: 20 May 2016 03:32 AM PDT I have a time field which stores an integer(minutes).

Code of Article's view show.html.erb: <p> <strong>Title:</strong> <%= @article.title %> </p> <p> <strong>Text:</strong> <%= @article.text %> </p> <h2>Comments</h2> <%= @article.comments.each do |comment| %> <p> <strong>Commenter:</strong>> <%= comment.commenter %> </p> <p> <strong>Comment:</strong>> <%= comment.body %> </p> <% end %> <h3>Add a comment</h3> <%= form_for([@article, @article.comments.build]) do |f| %> <p> <%= f.label :commenter %> <%= f.text_field :commenter %> </p> <p> <%= f.label :body %> <%= f.text_area :body %> </p> <p> <%= f.submit %> </p> <% end %> <%= link_to 'Edit', edit_article_path(@article) %> <%= link_to 'Back', articles_path %>
