I write a template for my form like
<h1>{% block formtitle %}{% endblock %}</h1>
<form method="post" action="">
{% csrf_token %}
[stuff]
<button type="submit">{% block formbutton %}{% endblock %}</button>
</form>
now i want to use the same template both for the creation and for the edit of an object, but how?
i tried to create a template for the creation like
{% extend "base.html" %}
{% include "form.html" %}
{% block formtitle %}Create a new MyObject{% endblock %}
{% block formbutton %}Create{% endblock %}
but i got a blank page...
You have to {% extend "form.html" %} in order to override those blocks. Blocks are overriden only for the template in the extend declarations.
A solution would be to create a new template for the new form that extends the old one:
{% extend "base.html" %}
{% include "my_form.html" %}
# my_form.html
{% extend 'form.html' %}
{% block formtitle %}Create a new MyObject{% endblock %}
{% block formbutton %}Create{% endblock %}
Or pass variables to the include statement:
{% extend "base.html" %}
{% include "form.html" with formtitle='Create new MyObject' formbutton="My button title" %}
# form.html
<h1>{% block formtitle %}{{ formtitle }}{% endblock %}</h1>
<form method="post" action="">
{% csrf_token %}
[stuff]
<button type="submit">{% block formbutton %}{{ formbutton }}{% endblock %}</button>
</form>

I'm not seeing an error when template inheritance seems to fail. I don't see content from the child template but I don't see a 'TemplateNotFound' error. If I change the path to the parent template to 'notthefilename.html' I still don't see an error. Is there a way to make template inheritance fail noisily? I have no idea why this is not working even though I have a similar inheritance in a adjacent folder that is working as expected.
generic_create.html The text 'hello2' is rendering.
{% extends "base.html" %}
{% load crispy_forms_tags %}
{% block content %}
<div style= "padding-top: 30px">
<form method="post">{% csrf_token %}
{% if model_name == 'TransactionsTable' %}
<div>
{% block transactions_create %}
hello2
{% endblock transactions_create %}
</div>
{% else %}
{{ form |crispy }}
{% endif %}
<div id="container">
<input type="submit" class="btn btn-default" value="Save">
Cancel
<div>
</form>
</div>
{% endblock content %}
transactions_create.html - The content 'Hello1' is not rendering
{% extends "generic_create.html" %}
{% load static %}
{% block transactions_create %}
Hello1
{% endblock transactions_create %}
Thanks to #Daniel Roseman's comment I realized I was performing the inheritance backwards. I was also over-complicating things. Using the include tag I was able to perform the sort of inheritance I was hoping to achieve very easily.
generic_create.html
{% extends "base.html" %}
{% load crispy_forms_tags %}
{% block content %}
<div style= "padding-top: 30px">
<form method="post">{% csrf_token %}
{% if model_name == 'TransactionsTable' %}
<div>
{% include "transactions_create.html" %} #NOTE: Here I removed the block and added 'include'.
</div>
{% else %}
{{ form |crispy }}
{% endif %}
<div id="container">
<input type="submit" class="btn btn-default" value="Save">
Cancel
<div>
</form>
</div>
{% endblock content %}
transactions_create.html
Hello1 #removed all of the extend and 'block' code. 'include' just renders the html directly.
That's it! 'include' really simplified things.
I am using allauth to handle all my authentication. Using that app each piece of authentication functionality is given its own template. However, I want to include the registration form in all other templates. i.e. the registration form is present in /account/login/, /account/password/change ... etc...
I decided to achieve that by including signup.html in base.html which is extended in all other templates. Like this:
base.html
...
<h4 class="card-title text-center">Register</h4>
{% include "account/signup.html" %}
...
account/base.html
{% extends "base.html" %}
account/signup.html
{% extends "account/base.html" %}
{% load i18n %}
<p>{% blocktrans %}Already have an account? Then please sign in.{% endblocktrans %}</p>
{% for message in messages %}
<span style="color:red;">{{ message }}</span>
{% endfor %}
<form class="signup" id="signup_form" method="post" action="{% url 'account_signup' %}">
{% csrf_token %}
{% for field in form %}
<div id="input-group">
{{ field }}
</div>
{% endfor %}
{% if redirect_field_value %}
<input type="hidden" name="{{ redirect_field_name }}" value="{{ redirect_field_value }}" />
{% endif %}
<div class="card-footer text-center">
<input type="submit" class="btn" value='{% trans "Get started" %}'>
</div>
</form>
account/login.html
{% extends "account/base.html" %}
{% load static %}
{% load i18n %}
{% load account socialaccount %}
{% get_providers as socialaccount_providers %}
{% block general_notice_modal %}
{% endblock general_notice_modal %}
{% block login-modal %}
...
This code causes the following error, which only occurs when I add the {% include %} tag in base.html
I think the code below:
{% include "account/signup.html" %}
should be in "account/base.html" not in "base.html".
You have an error because your "base.html" call "account/signup.html" and your "account/signup.html" call "account/base.html" who call himself "base.html". You have a loop.
I have two types of blog articles. Regular blog articles, and translation articles. They both have different html markup. I have a boolean variable translation_bool in my models to check if it is a translation article or not. If it is I want it to display my {% block translation %} and if not {% block translation %}. It worked with plain html code and not using html tags. But I had so much reusable code that it got troublesome to manage.
So my question is: why is this happening despite it being inside of an if statement.
Article template:
{% extends "base_generic.html" %}
{% load static %}
{% block js %}...{% endblock %}
{% if blogpost.translation_bool == True %}
{% block translation %}....{% endblock %}
{% else %}
{% block content %}...{% endblock %}
{% endif %}
{% block sidebar %}....{% endblock %}
In Base Generic Template:
<div class="row">
<div class="col-md-1"></div>
<div class="col-md-8">
{% block content %}{% endblock %}
{% block translation %}{% endblock %}
</div>
<div class="col-md-3">
{% block social_media %}...{% endblock %}
{% block sidebar %}...{% endblock %}
</div>
</div>
</body>
This is because blocks not defined in child template will render value from parent template. So in your case you should perform validation inside parent template. Or if it's impossible override blocks in child with empty content:
{% block translation %}
{% if blogpost.translation_bool == True %}
{{ block.super }}
{% else %}
{% endif %}
{% endblock %}
{% block content %}
{% if blogpost.translation_bool == False %}
{{ block.super }}
{% else %}
{% endif %}
{% endblock %}
Note {{ block.super }} will render content from parent template.
I have set up the following templates
base.html
{% extends 'base/main_base.html' %}
{% block main-content %}
<h1>Header stuff<h1>
...
{% block article-content %}
{% endblock %}
{% endblock %}
article.html
{% extends 'base.html' %}
{% block article-content %}
<h2>Content</h2>
<p>More content</p>
{% endblock %}
Now, I connected a view to the article.html, and I want use the dynamic view data to overwrite the 'header stuff' in the 'base.html' template. Problem is, the view is connected to the article.html, which inherits from the base.
Is there a way to override parts of the base template from the child template?
You could create another template block in your base.html
{% extends 'base/main_base.html' %}
{% block main-content %}
<h1>{% block header %}Header stuff{% endblock %}<h1>
...
{% block article-content %}
{% endblock %}
{% endblock %}
and overwrite the block in your article.html
{% extends 'base.html' %}
{% block header %}My overwritten headline{% endblock %}
{% block article-content %}
<h2>Content</h2>
<p>More content</p>
...
{% endblock %}
You could also check, in base.html, if a "header" value is injected to the template from the article (or any other view):
base.html
{% extends 'base/main_base.html' %}
{% block main-content %}
<h1>
{% if header %}
{{ header }}
{% else %}
Header stuff
{% endif %}
<h1>
...
{% block article-content %}
{% endblock %}
{% endblock %}
I want to add some flexibility to my layout template, but I can't find any way to do so.
I'm looking for a way to extend my layout template with variable, i.e. to pass a variable up in the template tree, not down.
# views.py
def my_view_func(request):
return render(request, "child.html")
# child.html
{% extends 'layout.html' with show_sidebar=True sidebar_width_class="width_4" %}
<div>Templates stuff here</div>
# layout.html
{% if show_sidebar %}
<div class="{{ sidebar_width_class }}">
{% block sidebar %}{% endblock %}
</div>
{% endif %}
I have to maintain four templates with a difference in a few lines of code. For example, I have two templates that differ from each other by a sidebar width class. Am I doing something wrong?
I suspect that block is what you are looking for in the first place.
Form your block inside the base template like this:
{% block sidebar_wrapper %}
{% if sidebar %}
<div class="width{{sidebar_width}}">
{% block sidebar %}{% endblock %}
</div>
{% endif %}
{% endblock sidebar_wrapper%}
And on your child template:
{% extends 'layout.html' %}
{% block sidebar_wrapper %}
{% with sidebar=True sidebar_width=4 %}
{{ block.super }}
{% endwith%}
{% endblock sidebar_wrapper%}
What you need is an include template tag. You can include a template in another template and render that with specific context.
{% include 'layout.html' with sidebar=True sidebar_width=4 %}
Check docs here: https://docs.djangoproject.com/en/2.2/ref/templates/builtins/#include
You can achieve this with some technique. I'll show the code then explain below.
# layout.html
{% block content %}
{% if show_sidebar %}
<div class="{{ sidebar_width_class }}">
{% block sidebar %}{% endblock %}
</div>
{% endif %}
{% endblock %}
# child.html
{% extends 'layout.html' %}
{% block content %}
{% with show_sidebar=True sidebar_width_class="width_4" %}
{{ block.super }}
{% endwith %}
{% endblock %}
In layout.html, wrap everything inside {% block content %}
In child.html, {{ block.super }} is like python's super(), which renders everything in the parent template's block. So if you wrap it inside {% with %} tag, all variables that you declare there will be available inside the parent template as well.
