I am finding myself writing helpers to make my views very clean; however helpers don't naturally come as classes, just a collection of methods inside of a module. As a result, these methods don't share data like there would if initialized were called with params. So I end up passing around data multiple times. It's annoying. Is there a way to put there in a class that shares values?
Here's an example I am trying to dry up -- and yes, it's far from optimal code, please just focus on the issue I'm trying to sort through; I'd rather not waste time with making a perfect example. In the below, options are being passed in but but I end up passing them to additional methods, etc.
module Dashboard::DashboardHelper
def menu_item(link_ref, options={})
title = options.fetch(:title, "")
details = options.fetch(:details, "")
highlight = options.fetch(:highlight, false)
icon = options.fetch(:icon, "")
first = options.fetch(:first, false)
subs = options.fetch(:subs, [])
link_item_class = (first) ? "m-t-30" : " "
content_tag(:li,
menu_link_label(link_ref,title,details,icon,highlight),
class: link_item_class
)
end
def menu_link_label(link_ref, title, details, icon, highlight)
link_to(menu_labels(title,details), link_ref, class: "detailed") +
icon_thumbnail(icon,highlight)
end
def menu_labels(title, details)
content_tag(:span, title, class: "title") +
content_tag(:span, details, class: "details")
end
def icon_thumbnail(name, family, highlight=true)
classes = (highlight) ? "bg-success icon-thumbnail" : "icon-thumbnail"
content_tag(:span,icon(name, family), class: classes)
end
def icon(name)
(name.present?) ? content_tag(:i, nil, class:"fas fa-#{name}") : ""
end
end
Edit:
The options hash comes directly from the view usually in the below form:
<%= menu_item dashboard_root_path,
title: "Dashboard",
details: "12 New Updates",
icon: "fe:home",
first: true,
highlight: true
%>
There's nothing stopping you from having some classes on your own in e.g. app/view_helpers
and using them in your views
# app/view_helpers/menu.rb
class Menu
attr_accessor :options
def initialize(options={})
# do something with your options
# self.options[:header] = options.fetch(:header, '')
end
def header
# use your options here
content_tag(:h1, options[:header])
end
end
# some_controller.rb
def index
@menu = Menu.new
end
# index.html.erb
<%= @menu.header %>
