Where does the html code live inside an appex page? - oracle

I want to update html code of the page inside an apex app but cannot find it. Is there a way to see the HTML code of a page in apex app?

A page typically consists of regions. Regions can be various types (eg a report, a map, a data entry form etc). For many types of region, the majority of the content is generated by APEX itself, hence the term "low code".
But on most of them, you can add static html that appears at the start or end of the region, and there is a region type of "static content" where all of the content is defined by you at design time. Similarly, there is a region where all of the content comes from a PL/SQL procedure, where you are responsible for providing all the relevant HTML as output from that procedure.

Apex consists of html, css (to make it shiny) and javascript. The default css and javascript are stored in static files (check the page source for that) and the html is stored in the database.
The way the html is applied on a page region is by way of a template. Every component in apex (page, region, report, breadcrumb,button, ...) uses a template and that is just an additional property to check in the builder for that component.
To see all the templates in an app go to Shared Components > User Interface > Templates. To see which templates are referenced in a page check 'Page Shared Components' > Templates (in the left pane of the builder).
It is possible to change templates and even create your own - or you could copy one and modify it to your needs (which is easiest). However, to ensure smoother upgrades it is easier to stick with what is available out of the box.

Nightwatch Page Object hierarchy/re-use

I'd like to use Nightwatch's Page Objects system for UI components used across our app. Because nightwatch has their own way of reading/initializing them, I don't see a way of properly extending/re-using them.
For example I want an DateInputPageObject for "date fields". It would identify the label, input, date picker, etc.
I'd use it on any page with a date input field.
I would also like to extend page objects. For example, class FooModal extends Modal. The ModalPageObject would define selectors for elements all modals have - the overlay, container, close button, etc.
I can't find any way to do this in nightwatch, is it possible at all?
The problem is not with nightwatch per se as it's just following the basic structure of page object model BUT that is a very good question and it brings out one of the drawbacks of page object model.
Page object model has been around for some time and the problem with that is that it doesn't serve the needs of modern web applications that use component libraries & living style-guides and re-using components.
Personally I found it easier to use a global json file with all the components structured based on their type. e.g. labels, fields, buttons, etc.

Can somebody give me an eagle eye perspective on Magento blocks, layout and templates?

Can somebody give me an eagle eye perspective on Magento blocks, layout and templates and how they relate to each other?
I understood that blocks are the basic building-blocks that a page is made of and that they are kind of mini-controllers.
I also understood that layout brings these blocks somehow together.
But there is still some uncertainty about templates and how they relate to blocks and layouts and vice versa.
What are blocks?
There are basically 4 things you need to know:
There are two types of blocks: those that automatically render their
children and those that don't. Knowing which type you're using will
help you in debugging.
Magento blocks are essentially models that contain logic for your view templates. Mind you - this is not business logic, but it is logic
related to the display of the information you're presenting. This is
by definition presentational logic. If you're familiar with Zend
Framework's Zend_Layout you could draw a comparison between custom
view objects and layout helpers.
The template file assigned to a block object can execute code as if it is local to that object. That is, $this corresponds directly to
the block class.
Layout actions are a thing that people use.
Two types of blocks
There are two types of blocks at the end of the day - those that
render automatically and those that don't. Take notes because this is
on the Magento Certification exam!!
Auto-rendered blocks
When defined in a layout, any block of type core/text_list will
automatically render all its children. While core/text will
automatically render itself it really only should contain text and
therefore is not useful for layout purposes (though some clever things
can be achieved with them).
Other blocks
Any other block type will need to be rendered manually. Provide the
block an alias which can then be passed to getChildHtml, returning the
content which you then echo.
Layouts And Templates
As the name suggests, layout files are useful in rendering front pages
of Magento. Layout files are XML files that reside in in app > design
frontend > your interface > your theme > layout. Here, you can see that there are many layout files for any given module. Each Magento
module has its own layout files much like the customer module has the
customer.xml layout file, catalog module have catalog.xml layout file
etc. These layout files contain structural blocks and content blocks.
read the following blogs. it will clear your concepts for magneto.

http://code.tutsplus.com/tutorials/custom-layouts-and-templates-with-magento--cms-21419
Blocks are the building modules of a page. They can be treated as "bricks". Now every block comes inside a layout. Layout is used to define the "shape" of the page. Now templates are used to define the behaviour of a particular block. That means each block or "brick" will have different charateristic depend upon the template it is used.
That is, to construct a magento page, you need to define a layout first that will give you an idea of shape of that page. Now you fill the layout with blocks. Each blocks now concentrate on a particular section of the entire layout. That means depending upon the "nature" of block, each small section will behave differently. To define the unique nature of a particular section, blocks uses templates (templates actually holds the webpage building codes, ie html + js + php)
I hope that will give you a short idea.
Try to google this. I am sure there are lot of lot of tutorials, blogs available about this.

create dynamic template for joomla 1.5

there are tutorials on the web about gow to create index.html, css file and template.xml that contain placeholders. ok, i got it, it's simple. but i need a template that has some different views. for example:
-all pages have a topmenu, header, left sidebar, mainarea and a footer but:
-first page has no header .topmenu after which sidebar, mainarea and footer comes.
-second page has sidebar moved from left to right
-third page has four blocks (blocks for special offers) instead of mainarea.
as far as i can see, i need to create three standalone templates with unique set of placeholders for each template. because i can't see the way to change laarge mainarea placeholder with four placeholders for offers blocks on some pages. dynamically.
is there if-statements in joomla templates to simply determine a document id to view four placeholders instead of mainarea. or to not show header on the main page (f.e. doc. id="mainpage")
but i want it to be selectable like:
-this page has first case of that template (index_1.php)
-and that page has a second case of the same template (index_2.php)
like a selectbox.
is that possible?
I will make this an answer as opposed to a comment since I believe it will do what you are looking for.
Once your articles are setup and your links to them are established (the site has the info on it you're looking for), you can create the modules containing the data that you want shown from time to time.
Go to the module manager - on the right you should see 'module assignment' or something along the lines of 'display this module on the following pages'; you can then pick which pages you want the module to show on. You can specify all pages, none, specific pages, however you want.
This will enable you to show them only where needed however you like.
You can ALSO do this programatically inside the module (if you do custom HTML and use an extension like Sourcerer to add PHP to the module) with PHP should you want a little more flexibility, but just choosing the pages to show on should work for what you're doing.

How can I preview Virtuemart2 Order verification email layout changes?

I am trying to change the layout ( css/html structure) of Virtuemart 2 order verification emails. Problem is that I have to make a fake purchase each and every time I do a change in the 10 different files (located # components/com_virtuemart/views/invoice/order/tmpl) that create this email template.
The closest "preview" I got was this direct access url "http://domain.com/index.php?option=com_virtuemart&view=invoice&layout=invoice&format=html&tmpl=component&virtuemart_order_id=1401"
But again it loads Joomla's head/body elements not the actual email template.
So how can I have a "preview" of how the template looks like with my new changes BEFORE make an actual test purchase? Is this possible?
You shouldn't change the core files otherwise the next update of VirtueMart (of which there are many) will erase your changes.
You should use Joomla!'s template overrides which VM2 supports that way you can update as needed to new versions without loosing your changes. See this article on docs.joomla.org on "How to override the output from the Joomla! core" and this one on template overrides.
3. You need to add the &format=raw at the end of the link to retrieve just the output of the component with out the template/html body wrapped around it. Of course that relies on the component as well.
I was going to suggest using raw, but looking at the current VM2 it doesn't properly support the format=raw option. Looking at the mail layout in the invoice view it not structured to return it the way you expect, it actually generates a HTML version by default with a matching text only version.
The best I could come up given those two options
Return a close equivalent of the HTML email
http://domain.com/index.php?option=com_virtuemart&view=invoice&layout=mail&virtuemart_order_id=1401&tmpl=component
Return the text version, albeit wrapped in the html page... you may have to view the source to see your invoice text.

Question on using content from other cshtml pages in razor

I've read a couple of articles on using asp.net mvc3 razor (which I am fairly new to). I have a couple of .cshmtl pages which are like shared content (e.g. header). They are basically just html pages with one or two divs etc.
To embed this in my main page, do I just use #renderPage("page address"). Do I also need a call to #renderbody? Do I need to specify the/a page in the layout property?
Thanksa
I would put the common elements in a layout (or perhaps a partial view rendered by the base layout). In fact, that's what I did in an application I am now building and it works quite nicely. The one issue is whether or not you need View Model data populated by the controller and passed to that partial view. I did, so I used a base controller and populated the common elements in the view model (all of those also inherited from a base class that had the common properties) and used sections and then in the sections renderered the partial view or not, depending on the view's need.
You can create a Partial View for each of these and call:
#Html.Partial("ViewName")
Or you can use sections, or this article on sections might help too.
As you may or may not know, ASP.NET accepts HTML tagging.
So why not include your .aspx file with the HTML include tag?
Here's how:
<!-- #include virtual="path to file/include-file.html" -->
Ex:
<!--#include virtual="header.aspx"-->
I do this all of the time when writing an ASP.NET website.
Just place it wherever you want the code, from the included page, to show up.
