| Jquery datepickers date issue Posted: 30 Oct 2016 07:53 AM PDT I have a rails application where I am using jquery datepicker with 2 input fields like this. <input type="text" class="form-control datePicker" placeholder="Check In" id="dpd1" value="<%= (Date.today).strftime('%d-%m-%Y').to_s %>" name="arrival_date_disp"> <input type="text" class="form-control datePicker" placeholder="Check Out" id="dpd2" value="<%= (Date.today + 1).strftime('%d-%m-%Y').to_s %>" name="departure_date_disp">
Jquery code is like this - $("#dpd1").datepicker({ minDate : new Date, yearRange: "-90:+1", changeMonth: true, changeYear: true, altField : '#arrival_date', altFormat : 'yy-mm-dd', dateFormat : 'dd-mm-yy', numberOfMonths: 2 }); $("#dpd2").datepicker({ minDate : $("#dpd1").datepicker( "getDate" ), yearRange: "-90:+1", changeMonth: true, changeYear: true, altField : '#departure_date', altFormat : 'yy-mm-dd', dateFormat : 'dd-mm-yy', numberOfMonths: 2, setDate: "31-10-2016" });
The problem is there is only one datepicker instance being initialized for both fields and as such when I click open the datepicker it shows same date for both of them (obvious as same datepicker is being used). How do I show different date for second field ? first one second one |

| Rails eager_load with conditions on association Posted: 30 Oct 2016 07:09 AM PDT I have a Rails application which has Stations (weather stations) and Observations. The app shows many weather stations on a map with the current wind speed and direction. I have a method which is used on the stations#index method which selects the stations and joins the latest observation per station. class Station < ActiveRecord::Base has_many :observations def self.with_observations(limit = 1) eager_load(:observations).where( observations: { id: Observation.pluck_from_each_station(limit) } ) end end
Observation.pluck_from_each_station returns an array of ids. The observations table contains many thousands of rows so this is necessary to keep rails from eager loading thousands of records.
This method should return all the stations - whether the have any observations or not. However this is currently not the case. it "includes stations that have no observations" do new_station = create(:station) stations = Station.with_observations(2) expect(stations).to include new_station # fails end
From my understanding a LEFT OUTER JOIN should return all rows wether the there are any results in the joined table or not. Why is this not working as expected? This is an example of the SQL generated: SELECT "stations"."id" AS t0_r0, "stations"."name" AS t0_r1, "stations"."hw_id" AS t0_r2, "stations"."latitude" AS t0_r3, "stations"."longitude" AS t0_r4, "stations"."balance" AS t0_r5, "stations"."timezone" AS t0_r6, "stations"."user_id" AS t0_r7, "stations"."created_at" AS t0_r8, "stations"."updated_at" AS t0_r9, "stations"."slug" AS t0_r10, "stations"."speed_calibration" AS t0_r11, "stations"."firmware_version" AS t0_r12, "stations"."gsm_software" AS t0_r13, "stations"."description" AS t0_r14, "stations"."sampling_rate" AS t0_r15, "stations"."status" AS t0_r16, "observations"."id" AS t1_r0, "observations"."station_id" AS t1_r1, "observations"."speed" AS t1_r2, "observations"."direction" AS t1_r3, "observations"."max_wind_speed" AS t1_r4, "observations"."min_wind_speed" AS t1_r5, "observations"."temperature" AS t1_r6, "observations"."created_at" AS t1_r7, "observations"."updated_at" AS t1_r8, "observations"."speed_calibration" AS t1_r9 FROM "stations" LEFT OUTER JOIN "observations" ON "observations"."station_id" = "stations"."id" WHERE "observations"."id" IN (450, 500, 550, 600, 650, 700, 750, 800);

| Ruby on Rails building a pivot table Posted: 30 Oct 2016 06:34 AM PDT I have a database table stockdiaries. With columns: ID, PRODUCT, UNITS, REASON Sample values: 1,Apple,5,purchase 2,Orange, 8,purchase 3,Apple,-3,sale 4,Orange,-5,sale Then this joins products table from where I get product.NAME, product.CATEGORY and so on. In my view I want to display a table with columns: PRODUCT, SOLD, PURCHASED, STOCK And values: Apple,3,5,2 Orange,5,8,3 SOLD is the sum of units sold, PURCHASED the sum of units purchased. I really don't know what is the best approach in the first place. But is it possible to use in my view something like: <%= stockdiary.product.NAME %> <%= stockdiary.sold %> <%= stockdiary.purchased %> <%= stockdiary.stock %>
to show the columns I want? In other words is there a way I can define purchased in my model or controller to calculate sum(UNITS) where REASON=purchase? If yes what is the syntax to use? If no what approach should I follow then? |

I'm probably doing something wrong here, but I just can't seem to find it. |

| Rails has_and_belongs_to_many how to change default iforeign key and show list of results on csv Posted: 30 Oct 2016 05:56 AM PDT I have tables products and suppliers. And a joining table products_sup. I have in my model Product: has_and_belongs_to_many :suppliers, :join_table => "products_sup"
And in my model Supplier: has_and_belongs_to_many :products, :join_table => "products_sup"
In my view I would like to display list of suppliers for each product. But it returns Mysql2::Error: Unknown column 'products_sup.product_id' in 'on clause': Note that NAME is a column in suppliers db table. And products_sup is the joining table. The problem is that products_sup contains columns PRODUCT, SUPPLIER. While rails by default is looking for supplier_id and product_id. But I can't find the right syntax to change these default columns. The same way that for a belongs_to I would use `:foreign_key => 'custom_foreign_key_column' What should I use in my view and models to achieve it? |

| Rails: use REJECT_IF dependent on parent record and for specific action for nested attributes Posted: 30 Oct 2016 03:19 AM PDT In my app I am building to learn Rails and Ruby (am beginner), I have a polymorphic model between tag and annotation / document. These are implemented using nested fields and I need to validate the tag-fields using reject_if.
models set up using belongs_to :tagable, :polymorphic => true has_many :tags, :as => :tagable, dependent: :destroy accepts_nested_attributes_for :tags, allow_destroy: true
For tags related to annotations, this need to be the validations: validates :content, presence: true validates :tagtype, presence: true validates :key, on: :update, presence: true, if: 'key_position.blank?' && 'key_regex.blank?' validates :key_position, on: :update, presence: true, if: 'key.blank?' && 'key_regex.blank?', format: { with: /(^(-?\d+,\s){3}-?\d+$){1}/, message: 'numeric and as x1, y1, x2, y2'} validates :key_regex, on: :update, presence: true, if: 'key_position.blank?' validates :value_position, on: :update, presence: true, if: 'value_regex.blank?', format: { with: /(^(-?\d+,\s){3}-?\d+$){1}/, message: 'numeric and as x1, y1, x2, y2'} validates :value_regex, on: :update, presence: true, if: 'value_position.blank?' validate :valid_key_regex, on: :update validate :valid_value_regex, on: :update
def valid_key_regex @valid_key_regex ||= Regexp.new(self.key_regex) rescue => exception errors.add(:key_regex, exception) end def valid_value_regex @valid_value_regex ||= Regexp.new(self.value_regex) rescue => exception errors.add(:value_regex, exception) end
For tags related to documents, this need to be the validations: validates :content, presence: true validates :tagtype, presence: true
I can make two methods for the reject_if of annotations and documents respectively, my questions now are: - how can I check the action (on: :create, on: update...) for the separate attributes?
- how do I get specific error messages back to the user when saving the changes (I use simple_form)? (i.e. not reject silently?)
- how could I DRY the 2 separate methods in to one (if useful?)? Where to place it and how to check the related parent?
all advice, tips, examples welcome! |

| Rails add link to edit attribute from another model Posted: 30 Oct 2016 02:59 AM PDT If I have a model Product and a model Category. I have a table in products index showing products with columns like: <td><%= product.ID %></td> <td><%= product.NAME %></td> <td><%= product.category.NAME %></td>
It shows values like: 1,salad, vegetable 2,apple,fruit I want to be able to click on vegetable or fruit to edit them. I tried: <td><%= link_to product.category.NAME, [:edit, product.category] %>
This takes me to a page categories/1/edit which returns Couldn't find Product with 'ID'= Instead it should go to categories/edit/1 In my routes I have: match ':controller(/:action(/:ID))', :via => [:get, :post] resources :categories

| Undefined method "has_attached_file" for my ActiveRecord model Posted: 30 Oct 2016 12:17 AM PDT I followed the docs at https://github.com/thoughtbot/paperclip exactly to install implement paperclip in my app for image uploading. I am currently using gem 'paperclip', '~> 5.0.0.beta1'. After I did the migration, the four columns were added onto my schema properly: t.string "picture_file_name" t.string "picture_content_type" t.integer "picture_file_size" t.datetime "picture_updated_at"
My paperclip should therefore be installed correctly. However, when I proceeded to add the following two lines onto my model class: has_attached_file :picture, styles: { medium: "300*300>", thumb: "100*100" }, default_url: "/images/start_project3.jpg" validates_attachment_content_type :picture, content_type: /\Aimage\/.*\Z/
Everything broke. I try to create, search, or anything related to the model class in rails console, it yells at me with the following error: NoMethodError: undefined method `has_attached_file' for #<Class:0x0055bd71ec0228>
I have tried multiple versions of paperclip, from the earlier version 4.3.0 to the latest version of paperclip, but the problem persists. I also restarted my server in between changes and migrations, but that did not fix the problem. This is the migration that I performed: class AddAttachmentPictureToProjects < ActiveRecord::Migration def self.up change_table :projects do |t| t.attachment :picture end end def self.down remove_attachment :projects, :picture end end

| Postgres: Column updated but not detected. Posted: 29 Oct 2016 11:59 PM PDT So i initially had a foreign id tutor_id as type string. So i ran the following migrations. change_column(:profiles, :tutor_id, 'integer USING CAST(tutor_id AS integer)')
The problem is that there was data already created which initially contained the tutor_id as type string. I did read however that by using CAST, the data should be converted into an integer. So just to confirm i went into heroku run rails console to check the tutor_id of the profiles and tutor_id.is_a? Integer returns true. However i am currently getting this error ActionView::Template::Error (PG::UndefinedFunction: ERROR: operator does not exist: integer = text at character 66
Why is that so? Is the only way out to delete the data and to recreate it? (I'm assuming the information provided above is enough to draw a conclusion, else i will add the relevant information too.) |
| Why is Capybara still passing when I delete JS file? Posted: 29 Oct 2016 10:15 PM PDT I have a small Rails app which Capybara, Rspec and Webkit for testing. It's a CRUD app to create items.

Posted: 29 Oct 2016 10:28 PM PDT I was recently using Svbtle.com where they show a page immediately after logging out. It says "Goodbye.", along with link to go "Back to SVBTL".

| Creating a login macro for feature specs - Rails Posted: 29 Oct 2016 07:55 PM PDT I've seen apps use a macro before for creating logins for feature tests. I'm in the process of building out the configuration for my test suite and this is the final task I was hoping to accomplish. Basically I want to write this line in my tests login(user)
Instead of what I'm doing right now. create(:user) visit "/" click_link "Sign In" expect(current_path).to eql(user_session_path) fill_in "user_email", with: "robert@example.com" fill_in "user_password", with: "password" click_button "Log in"
If anybody know what I need that would be great! Thank you. |
| Query table without returning ActiveRecord_Relation Posted: 29 Oct 2016 07:43 PM PDT Basically I have an app that have a Projects table, and a project belongs to a Client (and the client has a column in the table for it's location). I've created a search feature where the idea is you search for the project by location then client. I was hoping to use JavaScript to filter out any clients that weren't from the selected locations. I followed a tutorial to do this, however the tutorial assumed that the client belonged to a location, and therefore I'm the below code doesn't seem to work. Is there a way to basically say 'If Client.location = one of the selected locations, show it' clients = $('#search_client').html() $('#search_location').change -> location = $('#search_location :selected').map(() -> return $(this).text(); ).get().join().split(','); console.log(location) options_array = [] for l in location options_array.push $(clients).filter('optgroup[label="'+l+'"]').html() if options_array $('#search_client').html(options_array.join('')) else $('#search_client').empty()

| Rails migration to change column type from text to json (Postgresql) Posted: 29 Oct 2016 07:16 PM PDT I've been trying unsuccessfully to change a column type in my Postgres database from text to json. Here's what I've tried... class ChangeNotesTypeInPlaces < ActiveRecord::Migration[5.0] def up execute 'ALTER TABLE places ALTER COLUMN notes TYPE json USING (notes::json)' end def down execute 'ALTER TABLE places ALTER COLUMN notes TYPE text USING (notes::text)' end end
Also... class ChangeNotesTypeInPlaces < ActiveRecord::Migration[5.0] def up change_column :places, :notes, 'json USING CAST(notes AS json)' end def down change_column :places, :notes, 'text USING CAST(notes AS text)' end end
Both of these return the same error... PG::InvalidTextRepresentation: ERROR: invalid input syntax for type json

| Making dates go back passed 2011 DateTime Generator on Ruby on Rails Scaffold Posted: 30 Oct 2016 08:11 AM PDT I am making a new site and I cannot get dates in a generated scaffold to go back passed 2011. The months , days, and time work perfectly. However, I cannot moved the year past back 2001. I am making an Astrology Porn site with a database of compatible female pornstars with an inputted zodiac sign. I hope you can help me fix the date issues I am trying to add Kianna Dior to the zodiac sign and she was born in 1969, so it will not work with rails 5 default generator for any dateTime columns that are generated via scaffold. |
| How do I convert this to a UJS request? Posted: 29 Oct 2016 05:35 PM PDT I have a Profile and that has_many :ratings. I have a set of JS controls that control the input of that rating on the profile looks like this: 
What I want to happen is whenever the controls are moved, it automagically updates the rating on that profile the background -- via UJS (or w/e is best per Rails 5). This is in my Profile#Show view: <div class="col-md-3"> <div class="profile-data"> <table class="table table-condensed"> <tbody> <tr> <td> <p> <button type="button" class="btn btn-danger m-r-sm slider-step-value" id="slider-step-value-speed">5</button> Speed </p> <div class="slider"></div> </td> <td> <p> <button type="button" class="btn btn-primary m-r-sm slider-step-value" id="slider-step-value-tackling">3</button> Tackling </p> <div class="slider"></div> </td> </tr> <tr> <td> <p> <button type="button" class="btn btn-success m-r-sm slider-step-value" id="slider-step-value-dribbling">9</button> Dribbling </p> <div class="slider"></div> </td> <td> <p> <button type="button" class="btn btn-danger m-r-sm slider-step-value" id="slider-step-value-passing">7</button> Passing </p> <div class="slider"></div> </td> </tr> </tbody> </table> </div> </div>
This is my profiles.js: $(document).on('turbolinks:load', function() { var sliders = $('.slider'); var buttons = $('.slider-step-value'); for ( var i = 0; i < sliders.length; i++ ) { var button = $(sliders[i]).prev('p').find('button')[0]; noUiSlider.create(sliders[i], { start: 5, step: 1, behaviour: 'tap', connect: [true, false], range: { 'min': 1, 'max': 10 } }); attachEvent(sliders[i], button); } function attachEvent(slider,button){ slider.noUiSlider.on('update', function( values, handle ) { button.innerText = parseInt(values[handle]); }); } });
How do I convert this to use UJS to update this record without needing a form? |
| Rails Geocoder gem & Google Autocomplete API - Query Limit Reached Posted: 30 Oct 2016 08:09 AM PDT I have tried to implement Google's autocomplete API, when user types a location and presses to enter, A map with markers load in another page. It looks exactly like Airbnb. Search, then map.. My problem is, lately I am getting an error of "query size limit reached". I have read all the posts about this issue here but could not find a solution. Basically, when user types an address as string, I get that string and use it for google maps' init lat & long. I use geocoder gem and server as Heroku. Here is how it looks like; @search = params[:search] if !@search.nil? && @search.strip != "" location = Geocoder.search(params[:search]) @initlat = location[0].latitude @initlng = location[0].longitude end
Why I am getting this error and how can I solve it? |
