I have three html-files:
base.html
page.html
comment.html
in page.html I extend base.html. In comment.html I extend page.html. Will comment.html extend base.html's blocks?
Yes, you can actually use as many levels of inheritance as you'd like. From The Django Book:
One common way of using inheritance is the following three-level approach:
(1) Create a base.html template that holds the main look-and-feel of your site. This is the stuff that rarely, if ever, changes.
(2) Create a base_SECTION.html template for each “section” of your site. For example, base_photos.html, base_forum.html. These templates
all extend base.html and include section-specific styles/design.
(3) Create individual templates for each type of page, such as a forum page or a photo gallery. These templates extend the appropriate
section template.

Yes, it will. Why not to try it yourself?

I have a flask-admin app with quite a number of custom templates. I want to add an html block at the top of every page in the app. The obvious solution would be to add it to every template (and don't forget to add it to any new custom templates) but I hope there might be a better solution, to specify the html I want in a single place and have all future new templates automatically have it.
To simply insert HTML snippets into your templates you could use
{% include 'template_file.html' %}
To automatically get all new templates to use the HTML block try the jinja2 template inheritance which all of your templates would need to inherit from. Docs
Is there a shared "master" layout in Django for HTML files similar to Rails application.html.erb? If not, is there a best practice on how to go about creating one?
In Django, the best practise is to use three levels of template using template inheritance.
I quote the django book to explain you:
You can use as many levels of inheritance as needed. One common way of
using inheritance is the following three-level approach:
Create a base.html template that holds the main look and feel of
your site. This is the stuff that rarely, if ever, changes.
Create a base_SECTION.html template for each “section” of your site
(e.g., base_photos.html and base_forum.html). These templates
extend base.html and include section-specific styles/design.
Create individual templates for each type of page, such as a forum
page or a photo gallery. These templates extend the
appropriate section template.
This approach maximizes code reuse and makes it easy to add items to
shared areas, such as section-wide navigation.
To utilize django's own provided templates like forgot password, change password and such templates and views funcionality, I made my own templates for login e.t.c. But after some time I found that there are many views and templates already present that one can utilize just by providing right URL but only problem is that these templates are extending django's own template. So I want to know that is there a way to only set extended template of my own choice that is my site's main template so that I just give the URL of forgot password or change password e.t.c. related pages and django render the template by extending my main template instead of django's own template. I am not sure if admin panel is extending the same template that other pages are.
Please tell how can I do so and also please tell if doing so can have any problem.
More detail:
I know inheritance and extending with our template file but how can I set my own template in such way that they automatically inherit mine.
For example, for forgotpassword, I had to make a template file and need to paste form elements and top of it I write {%extends main.html%} but I don't want that, I know that default forgot password template is being inherited from some default django template I want to set it some so that it always inherit from my template in that case.
Short answer: You have to write your own templates.
Longer answer:
Django does include some templates, but these are all intended solely for the admin application. The auth views default to using 'registration/some_template.html', and those templates all live in the admin app ( see https://github.com/django/django/tree/master/django/contrib/admin/templates/registration). The auth views all support a template keyword argument that you can supply in your URLConf, so that you can specify which of your own templates to use.
Think of the admin templates as a reference that you can use when writing your own templates, but not as something you're meant to use directly.
Try to get your head around template inheritance. I think you can achieve what you want using template inheritance. This is a good post introducing the topic.
I'm working on my first Django project and have my templates setup with a base that all the others extend. In that base I want to have some user-specific navigation which means loading some values from the database to build the contents of a drop down menu. However I don't want to have to do this inside each view. Coming from Symfony2/Twig I would normally do this using a sub-request where I tell the template to render a view and that will use it's own template. Using syntax like:
{% render 'Bundle:Controller:action' with {} %}
How would I accomplish this same thing with Django? I've read over the docs a couple of times but can't find any way to do this.
You have two approaches:
(better)
- add the code to base.html (the one you're always extending) and only override it when you need to.
or
(worse)
- in every template use {% include %} to include your menus.html template.
Update: re-reading your question: you could modify the request in context-processor so your base.html would then have this information.
Custom template tags are what you want.
When particularly extend template and when to use include ? Is include of any use with content like user profile section (like about me in the corner of our site) ?
Extending allows you to replace blocks (e.g. "content") from a parent template instead of including parts to build the page (e.g. "header" and "footer"). This allows you to have a single template containing your complete layout and you only "insert" the content of the other template by replacing a block.
If the user profile is used on all pages, you'd probably want to put it in your base template which is extended by others or include it into the base template. If you wanted the user profile only on very few pages, you could also include it in those templates.
If the user profile is the same except on a few pages, put it in your base template inside a block which can then be replaced in those templates which want a different profile.
See about django template inheretance.
Extends sort of 'includes' the parent template and then can overwrite parts of it for different functionality.
Include does a simple include rendering a template in a current context.
extends creates "parent child relation". There is a chance of over-writing of parent functionality in case of extends. While include simply renders the html response.
Using % include ... with see docs allows to override variables from included page. So could not agree with muhammad-awais-bin-majid answer.
Suppose these two clauses just represent different ways of the pages constructing:
extends - to use like an external wrapper for the page,
include - to insert included page inside the current one.
Also one can use several extending pages just in chained nesting,
but including allow us to use several included pages one by one and not only in chained nesting.
