    end
  end

  def destroy
    log_out

I still can't understand why is this happening.

tried everything to solve on my own but can't.

I'm working on implementing a search feature in my Ruby on Rails with Diacritic Search Matching Exact Word

 if params[:name]
      name_normalized = params.unicode_normalize(:nfkd).gsub("_", "\\_")
      brands = brands.where("name LIKE ?", "%#{name_normalized}%")
 end

When I search for the diacritic character "š" in the database, the search query does not return any results, even though there is a record with the name "Tešt" containing that character.

If I modify the query to make it diacritic, it returns results like "testing," "Test," "Tešt," and "demo_Test" when searching for "š." However, my desired result is only the exact match "Tešt" because I was specifically searching for this particular word.

Despite all this, the search still doesn't fetch the desired results. I suspect there might be an issue with the query or how I'm handling the search term.

I have used .gsub("_", "\\_") to handle cases involving underscores in my query, and it is working as expected. If I use it in the query alone, it functions correctly.

Can anyone please guide me on how to implement a diacritic search properly using Ruby on Rails and SQL? Any insights or suggestions would be greatly appreciated. Thank you!

Ruby Datetime Error no implicit conversion of nil into String

I am getting the error "TypeError: no implicit conversion of nil into String" in Datetime method (ruby) and I wonder why my code is not working accordingly if I already have exception implemented. Any explanation about this or how to get rid of it?

        parse_datetime(raw_payload[:datetime])
      rescue ArgumentError

how to delete a record and go to delete page in rails 7 after installing ujs?

I am using Rails 7 and also install ujs but whenever i click on delete button Get request call rather than destroy request and i go to view record page rather then delete employee page. This is the code of delete link:

<%= link_to "Delete", employee_path(employee), method: :delete, class: "btn btn-danger", data: { confirm: "Are You sure to delete this employee" } %>

and this is the code of delete action from controller file:

def destroy
    @employee = Employee.find(params[:id])
    if @employee.destroy
      redirect_to employees_path, notice: "Employee has been deleted"
    end
  end

Working on ruby on rails and caught in a situation where i can't determine why is it doing like that

I am working on a project called foodlog where the person can enter the food they eating the number of calories ,protiens, carbs, fats etc. The issue i am facing is if i create 2 entries in it , the display will show 4 of them if i place 3 entries in it, then 9 and so on . it's just reshowing the entries after each iteration and i can't determine why's that.

I have uploaded it on my github if anyone has time pls help. https://github.com/s-chuck/git_test in my opinion the problem is most probably on views folder and in views/_entry.html.erb file.

i have tried doing everything and i am expecting the entries should only be showed once in my website.

active admin gem error message just following the instructions

I am using ruby 3.1.3, rails 7.0.5 and activeadmin 3.0.

I just followed the installation instructions from the activeadmin website, but I got the following error:

searchable. Define a `ransackable_attributes` class method in your `AdminUser`

example, `encrypted_password`, `password_reset_token`, `owner` or
other sensitive information). You can use the following as a base:

ruby

Datatables buttons (export to excel) not displaying - Javascript /Ruby

Here I'm trying to add default excel export functionality for my JS project,

in profiles.js I have following code,

initDataTable({
    tableId: "#profilesStatusTable",
    orderVal: 1,
    sortingDirection: "asc",
    targetsVal: [0, 7],
    dom : 'Bfrtip',
        buttons : [ {
            extend: 'excel',
            text: 'Export To Excel'
        } ]
  });

      //Existing code for filter purpose
  $("#organizationFilterDropdown").dropdown();

  
  $("#organizationFilterDropdown").dropdown({
    onChange: function(value, text, $choice) {
      if (value === "Organisation") {
        // Reset option selected
        resetTableRecords(); // Call the function to reset the table records
      } else {
        var selectedOrganizationId = value;
        console.log(selectedOrganizationId);
  
        var profilesStatusTable = $("#profilesStatusTable").DataTable();
  
        profilesStatusTable.column(5).search(selectedOrganizationId).draw();
        
      }
    }
  });

But I cannot see any buttons , I also tried applying following in order where the table is implemented _status_table.html.erb,

How to add alt-text to images attached to model via Cloudinary Active Storage?

I'm working on a project that has_many_photos_attached to a Project model. I'm attaching photos to each new instance of Project via Cloudinary Active Storage in my Seeds like so: file = URI.open("URL_TO_PHOTO") project.photos.attach(io: file, filename: "PHOTO.png", content_type: "image/png")

When I want to display the photo(s), I do the following: <% @project.photos.each do |photo| %> <%= cl_image_tag photo.key %> <% end %>

I want to be sure that my site is accessible, so I want to add 'alt-text' to all my images. However, I'm not sure where this can be done - ideally I would add the alt text when I attach the photo in the seeds.

I'm using Ruby and Ruby on Rails.

Anyone have any ideas?

I've tried adding it simply here:

<% @project.photos.each do |photo| %> <%= cl_image_tag photo.key alt="alt text goes here" %> <% end %>

but received the following error from rails: "wrong number of arguments (given 1, expected 0)"

Difficulties to create in database with cocookn / nested form

Good morning

I've been trying to save the content of a nested form in a database for a while now. I have a main form dependent on the Supplier model, and I have another SupplierRestaurantDelivery model which is there to define A delivery_day = day on which the restaurant can be delivered An order_day = day for which you must order to be delivered on delivery_day (display via javascript if delivery_day is checked) A max_hour_order = valid for all delivery_day

The purpose of the SupplierRestaurantDelivery model is to be able to calculate the possible delivery days for a restaurant.

Here are my three models:

class Supplier < ApplicationRecord
  has_many :ingredients
  has_many :supplier_orders
  has_many :supplier_restaurant_deliveries, inverse_of: :supplier
  accepts_nested_attributes_for :supplier_restaurant_deliveries, reject_if: :all_blank, allow_destroy: true

  validates :name, uniqueness: { case_sensitive: false }
  validates :franco, presence: true, numericality: { greater_than: 0 }
end

class SupplierRestaurantDelivery < ApplicationRecord
  belongs_to :restaurant, inverse_of: :supplier_restaurant_deliveries
  belongs_to :supplier, polymorphic: true
end

class Restaurant < ApplicationRecord
  belongs_to :company
  has_many :supplier_orders, dependent: :destroy
  has_many :user_restaurants
  has_many :users, through: :user_restaurants
  has_many :supplier_restaurant_deliveries
end

Here is my controller:

class SuppliersController < ApplicationController
  def index
    @suppliers = policy_scope(Supplier)
  end

  def new
    @supplier = Supplier.new
    @supplier.supplier_restaurant_deliveries.build
    authorize @supplier
  end

  def create
    @supplier = Supplier.new(supplier_params)
    puts "=======>>>>>  Create supplier"
    # @restaurant_id = current_user.current_restaurant_id
    puts "=======>>>>>  ID restaurant #{@restaurant_id}"
    @supplier.restaurant_id = current_user.current_restaurant_id
    # @supplier.update(restaurant_id: @restaurant_id)
    puts "=======>>>>>  errors :  #{@supplier.errors.full_messages}"
    puts "=======>>>>>  Restaurant added to :  #{@supplier}"

    if @supplier.save
      puts @supplier.errors.full_messages
      puts "=======>>>>>  I just pass @supplier.save "
      create_delivery_entries
      puts "=======>>>>> I just pass create_delivery_entries "

      redirect_to suppliers_path, notice: "Supplier was successfully created."
    else
      puts @supplier.errors.full_messages
      render :new, status: :unprocessable_entity
    end
    authorize @supplier
  end

  def create_delivery_entries
    delivery_days = params[:supplier][:supplier_restaurant_deliveries_attributes]["0"][:delivery_day] # Les jours de livraison sélectionnés
    order_days = params[:supplier][:supplier_restaurant_deliveries] # Les jours de commande pour chaque entrée
    puts "=======>>>>>  Delivery Days: #{delivery_days.inspect}"
    puts "=======>>>>>  Order Days: #{order_days.inspect}"

    delivery_days.each_with_index do |selected, index|
      day = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday'][index]
      puts "Day: #{day}, Selected: #{selected}"
      puts "=======>>>>>  index: #{index} // day: #{selected}"
      next unless order_days[index].present? # Ignorer l'itération si order_days[index] est nil

      order_day = order_days[index][:order_day]
      puts "=======>>>>>  order day: #{order_day}"
      @supplier.supplier_restaurant_deliveries.create(delivery_day: day, order_day: order_day, supplier_type: 'Supplier')
      puts "=======>>>>>  created ... "
    end
  end


  def edit
    @supplier = Supplier.find(params[:id])

  end

  def update

I see it's stuck in the settings. If I put supplier_restaurant_deliveries_attributes, it blocks at @supplier.save If I put supplier_restaurant_delivery_attributes, then it goes much further. We can observe in the console what is blocking. Another element that challenges me in this console: why do I have an array of 8 elements returned for the 7 days when I only announce the 7 days of the week?

I selected my example in delivery day: wednesday and order_day: Tuesday, as well as delivery_day: saturday and order_day: friday

Gem doesn't work when using js importmap tag but does work with js include tag. Is there a workaround?

I'm using the gritter gem and followed the documentation pretty much to the tee.

the gem works with: <%= javascript_include_tag 'application' %>

but doesn't work with:
<%= javascript_importmap_tags %>

Is it possible to make an older gem work with importmap_tags by importing it differently?
