partials

I have been using sendFile method to render Html in Express project. I would like to use partials with my project. And, not switch to jade. Is there a way to use traditional HTML with partials in Express 3.x. I have tried ejs, but dont understand it completely. A more 'HTML-like' templating engine would be nunjucks (whose syntax is similar to Jinja2, which you have experience with). Here's a simple setup. This assumes both Express and Nunjucks are installed, if not: npm install express npm install nunjucks – app.js var nunjucks = require('nunjucks'); var express = require('express'); var app =

I want to have some of my partials as markdown snippets. What is the easiest way to render them using the standard rails erb templating? Ideally, I'd like to do something like this: If I have a partial in app/views/_my_partial.md.erb : My awesome view =============== Look, I can **use** <%= language %>! which I reference from a view like so: <%= render "my_partial", :language => "Markdown!" %> I want to get output that looks like this: <h1>My awesome view</h1> <p>Look, I can <strong>use</strong> Markdown!</p> Turns out, the Right Way (tm) to do this is using ActionView::Template.register

In a rails application, in which situation would you use a partial and when would you use a helper? I find both very similar, since they represent markup fragments. Is there a convention around this? which is the 'rails way' of using them? Thanks! I guess my rule of thumb is to use a helper to build a single "unit" of display -- like a span containing a link -- and to use a partial to build a more complex unit of display composed of more than one "unit" of display -- like a grid or a menu. A partial is a view fragment, a piece of a view that is useful in multiple places and is pulled out so as

I've been a bad kid and used the following syntax in my partial templates to set default values for local variables if a value wasn't explicitly defined in the :locals hash when rendering the partial -- <% foo = default_value unless (defined? foo) %> This seemed to work fine until recently, when (for no reason I could discern) non-passed variables started behaving as if they had been defined to nil (rather than undefined). As has been pointed by various helpful people on SO, http://api.rubyonrails.org/classes/ActionView/Base.html says not to use defined? foo and instead to use local_assigns

It seems like rendering a page dynamically with AJAX in response to a submitted form is common. None of the other similar questions are focused around how to do this in a general way. The best blog post I could find on the subject was here: http://www.gotealeaf.com/blog/the-detailed-guide-on-how-ajax-works-with-ruby-on-rails The question: How do I code my rails application so that I can trigger a partial view to load via AJAX when I submit a form or click a link? Several things must be present for this to work, including the :remote => true flag on the triggering element, the respond_to :js
