In my Rails app I already have the following code:
<% %w(number_of_students edit_class_name tech_help).each do |modal| %>
<%= render "common/modals/#{modal}" %>
<% end %>
There will be a few more modals added into app/views/common/modals and instead of explicitly listing them out in the %w() I was wanting to loop through the common/modals directory and just render each file.
Here is what I came up with:
def render_modals
files = Dir.glob("#{Rails.root}/app/views/common/modals/*").collect { |file| File.basename(file, ".html.erb").sub("_", "") }.flatten
files.collect do |modal|
render partial: "common/modals/#{modal}"
end.join.html_safe
end
define a simple method in where is more appropriate (maybe app helper?) like this:
def modals
%w(number_of_students edit_class_name tech_help)
end
if you need these modals in a controller/model too, maybe you should define this method in an appropriate class? For example
class Modal
def self.types
%w(number_of_students edit_class_name tech_help)
end
end
Also, if you are rendering the templates often, then also define
def render_modals
modals.map do |modal| # Modals here should be the method that you just defined, example, Modal.types
render partial: "common/modals/#{modal}"
end.join
end
