Including another Pug view fails - node.js

I have three Pug files in a Node.js/Express application which follows the following layout:
//layout.pug
html
head
title= title
link(rel="stylesheet", href="link")
script(src="links")
// many css and javascript imports
body
header
// header section
block content
footer
// footer section
// more script imports
//index.pug
extends layout
block content
//some content
include slider
//slide.pug
div(class="xxx")
//slider contents
The include keyword actually works here and it renders the slider.pug but the problem I'm facing is that it does not render the slider.pug page as expected. The slider page is rendered in a way that it does not load required styles and javascript files so the result is a messed up html inside a nicely rendered one (index.pug in this case is the nicely rendered one).
I've tried adding the extend layout line to the slider.pug but it also failed.
What is the appropriate way to include a pug file that is meant to rely on the resources included in the layout page such as css and javascript inside another pug file?

How do I add an image to a list in Pug

Can't find an answer to this anywhere. I have a simple list in pug, and I thought I was supposed to use the syntax I have below. The image placeholder shows up and the styling (size) in the rendered website, but there is a 404 on the image in my Visual Studio console. I thought the image needed to be in the same folder as the index.pug file, which it is. Any ideas why it won't show up?
extends layout
block content
doctype html
html(lang="en")
head
meta(charset='utf-8')
meta(name='viewport' content='width=device-width, initial-scale=1')
section
nav
ul
li.title Study Bot
li.robot
img(src='robot-face.jpg' alt='Robot face' width='130px')
article
footer
iframe#encyclopedia-window(src='https://en.wikipedia.org/wiki/')
Images are static content. So we have to specify the directory for static assets.
So create a folder named public (or anything you like), place the image file in it.
Then in index.js(or your entry point):
app.use(express.static('public'))
Now path to image becomes:
src='/static/robot-face.jpg'

Express 4+pug disable layout

I want to ajax for blocks that without layout
Such as
extends layout
block content
p xxxx
I want to get the content in block
if !layout
include layout
The solution
If you don't want the standard pug layout then create a file that doesn't have extends layout in it:
doctype html
html(lang='en-us')
head
title Page Title
body
div Content goes here
You don't need to do anything in your app.js file to make this happen. You've probably figured out that none of the statements in your question work. This is all controlled in the pug template file.

can you use jade to only render the dynamic part of your html...and not mess with rest of your html

Or can you render partially and render rest later. So lets say when app starts up it renders most of the html. But when user abc wants to see his profile jade renders name to abc and merge it with regular pre rendered html and then you send it etc.
Rendering whole html pages at every request seems like a waste.
Converting all static html to jade seems like a annoyance that can be avoided. Slowly css became LESS and html became JADE?
I am lost on how to use jade I am learning express.
You can use Jade's compileClient function to create a function that will render predefined Jade code on the fly. (See the API reference.)
So, if you create a Jade file with the dynamic HTML, and compile that for the client, you can then call that function at a later time, and insert the resulting HTML string to the DOM.

Issue with Rendering templates with jade, express, and node.js

I'm new to node.js, jade, & express, so please bear with me.
I have the following files.
layout.jade
index.jade
extends layout
block content
label initial layout
form(action="/getReports", method="GET", enctype="multipart/form-data")
input(type='submit', value='Generate Report')
child.jade
extends index
block append content
label added child
server.js
app.get('/getReports', function(res, req)
{
res.render("child.jade");
});
Process:
User comes on and loads the site. They see the initial index page
User clicks on the form which triggers an action that calls the Rest
Api getReports
The call will render the child template that should just append "added child" to the content part of index.jade.
However, I'm not seeing this. I guess I'm trying to understand the best approach to append a partial template that is rendered to the original index.jade page.
The problem i'm having is that this code is the client side is the index.jade page. The button triggers an action call to the server. The server processes data, then the goal is to take the data and process a template that it was to display on the index.jade page.
Normally, without the jade template files, I would just use javascript and to the naive way which would be just have the client side java code trigger the ajax call and in the response use the DOM to append the html with the processed data but I wanted to take advantage of jade.
Any advice Appreciated,
Thanks,
D
Here are some pointers that might help you,
In res.render("child.jade");, don't include extension of the jade file, .jade. Just res.render("child"); will work.
In your "child.jade", block append content is wrong as there is no block with that name. If you want to render some partial in index page then you should specify a block in "index.jade". Make it like,
extends layout
block content
label initial layout
form(action="/getReports", method="GET", enctype="multipart/form-data")
input(type='submit', value='Generate Report')
block child
and "child.jade" to,
extends index
block child
label added child

Show a partial without the layout.jade file

I'm using layout.jade as a template for all the partials. layout.jade includes a header, footer, sidebar etc, and the partials is what is shown in the body.
Now I've implemented a lightbox with iframe, to show one of the partials in. The problem is that I don't want the header, footer etc to be shown inside the lightbox, just the partial jade file.
Is there a way to exclude layout.jade in this case?
Thanks in advance!
Yes, here's how:
res.render('template', { layout: false /* ... other parameters */ });
See Express docs on view rendering. You can also specify a different layout.
