When Ruby on Rails is combined with HTML and CSS and marked as selected, it will be displayed with

I'm currently in the process of developing my cookbook app and the next feature on my agenda is the grocery list functionality. Once on the recipe page, users will have the option to click on an "Add to Grocery List" link which will redirect them to a page containing all the ingredients needed for that particular recipe.

The idea is to display the ingredients individually, each with a checkbox next to it. My goal is to have a strikethrough effect applied to the ingredient text when the checkbox is ticked (~~Eggs~~), and for the text to remain normal when the checkbox is unticked. This is where I could really use some assistance. I understand that I will need to use If statements, but I'm unsure of how to implement them while achieving the desired outcome.

Currently, I have the ingredients stored using the text_area method, meaning that in order to distinguish between ingredients, the each_line function must be utilized.

Here is a snippet from the _grocery partial that I have constructed:

<% @recipe.ingredient.each_line do |line| %>
  <li><%= line %></li>
<% end %>

Since I am not using bootstrap, I am unsure of how to incorporate the checkbox and apply the ~~strikethrough~~ effect when the checkbox is selected. Any guidance or insights would be greatly appreciated. If additional code is required from my end, please do not hesitate to request it.

This particular aspect of the project has me feeling a bit out of my depth.

To apply a strike-through effect using only CSS is possible. To ensure the item's state is saved, it is recommended to utilize AJAX for automatic form saving. Alternatively, including a "Save List" button can mimic a typical form setup in Rails.

Here is a demonstration of using CSS to dynamically strike through an item when the checkbox is checked, or upon loading the page with the checkbox already checked.

.row input:checked + span {text-decoration: line-through}

<div class="row"><input type="checkbox"> <span>My item</span></div>
<div class="row"><input type="checkbox"> <span>My item</span></div>
<div class="row"><input type="checkbox"> <span>My item</span></div>
<div class="row"><input type="checkbox"> <span>My item</span></div>
<div class="row"><input type="checkbox"> <span>My item</span></div>

Upon page load, utilize Ruby to determine if the checkbox should be pre-checked, easily achieved with Rails' form helper. Let CSS handle the visual component from there :)

In addition to the fantastic CSS-only solution provided by Wes Foster, I'll get straight to the point for you...

It's important to note that your question pertains to front-end styling, not Rails.

While the information you've given is helpful, it appears that there might be some confusion regarding how the system should be integrated.

I have set up ingredients using text_area

Here is some code (the aforementioned approach may not be ideal).

Refer to Wes's solution as it will enhance the efficiency of your task:

#app/models/ingredient.rb
class Ingredient < ActiveRecord::Base
   has_and_belongs_to_many :recipes
end

# join table - ingredients_recipes - ingredient_id | recipe_id

#app/models/recipe.rb
class Recipe < ActiveRecord::Base
   has_and_belongs_to_many :ingredients
end

One of the main issues in your structure is manually adding "ingredients" to a recipe. It is strongly recommended to utilize a many-to-many relationship (either has_and_belongs_to_many or has_many :through) to link different records together.

In essence, this will enable you to implement the following:

@recipe.ingredients.each ...

#app/controllers/recipes_controller.rb
class RecipesController < ApplicationController
   def show
      @recipe = Recipe.find params[:id]
   end
end

#app/views/recipes/show.html.erb
<% @recipe.ingredients.each do |ingredient| %>
    <%= content_tag :li, ingredient, class: "ingredient" %>
<% end %>

#app/assets/stylesheets/application.css
li.ingredient:checked + span {  /* Wes's code */ }

This will display a list of ingredients for your recipe.

If you wish to add or remove ingredients from a recipe:

#app/models/recipe.rb
class Recipe < ActiveRecord::Base
   has_and_belongs_to_many :ingredients
   accepts_nested_attributes_for :ingredients
end

#app/controllers/recipes_controller.rb
class RecipesController < ApplicationController
   def new
      @recipe = Recipe.new
   end

   def create
      @recipe = Recipe.new recipe_params
      @recipe.save
   end

   def edit
     @recipe = Recipe.find params[:id]
   end

   def update
      @recipe = Recipe.find params[:id]
      @recipe.update recipe_params
   end

   private

   def recipe_params
      params.require(:recipe).permit(:recipe, :params, :ingredients)
   end
end

This will allow you to do the following:

#app/views/recipes/edit.html.erb
<%= form_for @recipe, method: :put do |f| %>
   <%= f.collection_check_boxes :ingredients, @recipe.ingredients, :id, :name %>
   <%= f.submit %>
<% end %>

With this setup, you can view the existing ingredients for your @recipe and update them upon submission.
