Rails 5 and 6 support this in a much more convenient manner that handles creating a request and whatnot behind the scenes: rendered_string = ApplicationController.render( template: ‘users/show’, assigns: { user: @user } ) This renders app/views/users/show.html.erb and sets the @user instance variable so you don’t need to make any changes to your template. It automatically … Read more
You can try this def index @books = Book.order_by(created_at: :desc) end it works fine.
If you’re using Rails 4+ you should just use the built-in truncate helper method, e.g.: <%= truncate item.description, length: 30, separator: /\w+/ %> The string “…” will be appended to truncated text; to specify a different string, use the :omission option, e.g. omission: “xxx”. For Rails 3.x the :separator option must be a string. Giving … Read more

You need to place a hidden field tag before each checkbox with an empty value, for example: <%= hidden_field_tag :basketball, ” %> <%= check_box_tag :basketball, checked = true %> Basketball</br></br> Then the form is aware it needs to populate that field with an empty value if nothing is selected.
You can map the result: Person.all.pluck(:id, :name).map { |id, name| {id: id, name: name}} As mentioned by @alebian: This is more efficient than Person.all.as_json(only: [:id, :name]) Reasons: pluck only returns the used columns (:id, :name) whereas the other solution returns all columns. Depending on the width of the table (number of columns) this makes quite … Read more
Your folder/file structure should look as follows: app/ models/ question/ document.rb answer.rb document.rb question.rb And then rails will automatically find the correct models (it will translate the model name to a filename, and namespaces are translated to folders). Make sure that inside your question/document.rb the class definition looks as one of the following alternatives: class … Read more
