Wagtail / Django inbuilt main menu - django

Started a project working with Wagtail CMS and what I understood of their principal of pages is that it is hierarchical leading me to the conclusion that pages are either parent/child related or siblings.
So how I have done it is have my main page landing and all other pages would be children of this page.
Here is my structure
Home page
/ | \
News About us Events
/ | \ / | \
n_item n_item n_item e_item e_item e_item
So they are 6 types of pages
Home page * (unique)
News * (unique)
n_item (News Item)
About Us * (unique)
Events * (unique)
e_item (Event Item)
I then ticked the "Show in menus:" in the promote tab for the starred pages (*) in the above list.
The n_item and e_item will allow the editor (non technical) person to add as many of these pages as they wanted as they will be listed as part of the contents in the "News" and "Events" pages respectively.
Ideally the editor should not create siblings to Home Page,News, About us and events. Is it also possible to limit wagtails functionality of where editors can add pages if they are not super users?
But there doesn't seem to be a clear simple way (maybe a tag) to generate my menu. This is what I have found in my research.
page url and slug url which i cant get to seem to work in every template that is not being referenced directly by that pages template. It would also mean its not that dynamic
django-simple-menu doesn't seem dynamic to me as i have to manual link pages in code. Plus if this is the way wagtail intended to do it, it seems like a waste of maintaining page hierarchy internally.
List item seems to have been deprecated but even if it wasn't it seems cumbersome for the same reasons as 1 and 2

I wanted to have automatically generated menu too but only first level with home. I might did something naive but it works. I am using Wagtail 2.5.1 and Django 2.2.2.
My Wagtail page structure look like this:
Home page
/ \
Blog About
/ | \
n_item n_item n_item
I am using bootstrap4 so this is my nav in base.html template:
{% with root_p=request.site.root_page %}
{# this is static item for home #}
<ul class="navbar-nav ml-auto">
<li class="nav-item">
<a class="nav-link {% if '/' == request.path %} active {% endif %}" href="{{root_p.url}}">{{root_p.slug}}</a>
</li>
{# Here I am looping home's childrens #}
{% for nav in root_p.get_children.live %}
{% if nav.show_in_menus %}
<li class="nav-item">
<a class="nav-link {% if nav.slug in request.path %} active {% endif %}" href="{{nav.url}}">{{nav.slug}}</a>
</li>
{% endif %}
{% endfor %}
</ul>
{% endwith %}
This is result:
Now I am able to change slug, tick/untick "show in menus" and my bootstrap menu reflect these changes.
EDIT:
My last answer does not solve custom order of menu items. We can order items by standard fields in Page model "first_published_at" or alphabetically by "title" name. But I needed make it custom. So I added custom integer field in each my page model. Then wagtail users can change order of menu items using "promote tab".
My current page structure look like this:
Home
/ | \
Case studies Services Contact
My page model: (example of services only)
class ServicesPage(Page):
template = "home/services.html"
max_count = 1
subpage_types = []
menu_order = models.IntegerField(default = 0, help_text = "Setup custom menu order")
promote_panels = Page.promote_panels + [
FieldPanel('menu_order'),
]
class Meta:
verbose_name = "Services"
verbose_name_plural = "Services"
This is how it looks in promote tab of each page model
Last step is edit navbar loop in base template:
{% with root_p=request.site.root_page %}
{% for nav in root_p.get_children.specific.live|dictsort:"menu_order" %}
{% if nav.show_in_menus %}
<li class="nav-item {% if nav.slug in request.path %} active {% endif %}">
<a class="nav-link" href="{{nav.url}}">{{nav.title}}</a>
</li>
{% endif %}
{% endfor %}
{% endwith %}
For ordering I am using default django template filter dictsort.
I guess it is not best way how to do that, but it works.

Django-cms, children variable in template, page navigation doesn't show in newer version

I'm trying to run project using Django-cms 3.6.0. It was created using Django-cms 2.3.8, I'm trying to use the old code. In this new version the menu with subpages links doesn't appear. children variable in template doesn't seem to contain anything.
I expect it to show links to 4 subpages of a page. I've added pages manually in admin UI in new version of django-cms.
subbase.html:
{% extends "base.html" %}
{% load i18n %}
{% load menu_tags cms_tags %}
...
{% block left_menu %}
<nav id="lMenu">
{% show_menu 1 1 0 1 "menu/sub_menu.html" %}
{% block left_content %}{% endblock left_content %}
</nav>
{% endblock left_menu %}
sub_menu.html:
{% load menu_tags %}
<ul class="subMenu">
{% for child in children %}
<li>{{ child.get_menu_title }}</li>
{% endfor %}
</ul>
I've checked in database, using manage.py shell, that those pages has child pages:
from cms.models.pagemodel import Page
pages = Page.object.all()
children = pages[2].get_descendant_pages()
And now, e.g., calling pages[2].get_menu_title(), children[0].get_menu_title() returns expected proper names of the pages, as added through UI.
I haven't found much about this children variable in docs. Should this still work this way in 3.6? What is the proper way to refer to child pages in template?
I've found, that I had something wrong with language settings. Menu with subpages links started to appear after I:
used i18n_patterns in main project urls.py file
added CMS_LANGUAGES in settings.py according to docs http://docs.django-cms.org/en/latest/reference/configuration.html#cms-languages
added pages in both languages through cms admin page. Before I had page in only one language.
Can't remember exactly which one fixed issue with submenu.
Also maybe something were wrong with urls handling, I used django apps urls from urls.py instead of cms.urls.

How to display {% django block %} dynamically with for loop?

Hello Awesome People!
I'm building a dashboard for my website, in the left section, I have a menu containing multiple items : Home, Messenger, Job Offers ....
When creating an account, Users are able to choose their items, re-order or remove.
I have Menu & Item models,
class Menu(models.Model):
items = models.ManyToManyField('Item',blank=True)
class Item(models.Model):
name = models.CharField(max_length=100)
unique_key = models.CharField(max_length=100,unique=True)
url = ......
For the menu of the user, in my base_template I display the items of the current users with for loop. With a CSS class I want to highlight the current view, the current item.
When the user visits his messenger, I want to highlight that item messenger with a CSS class.
<ul>
{% for item in user.menu.items.all %}
<li class='{% block item.unique_key %}{% endblock %}'>
{{item.name}}
</li>
{% endfor %}
</ul>
Now, when being in messenger.html for example, knowing that I have a unique_key for messenger called item_messenger, I do
{% block 'item_messenger' %}active{% endfor%}
It's not working, the item Messenger or whatever I choose doesn't become highlighted, I wonder why?
Is there another way to achieve that?
Any hint will be helpful, thanks in advance!
You are trying to have the block tag interpret a variable as it's name. That doesn't work.
You will need to pass along the active item's key in the template context and then in your base_template you can just do a simple if statement to add the active class to the correct entry.
<ul>
{% for item in user.menu.items.all %}
<li class='{% if item.unique_key == active_key %}active{% endif %}'>
{{item.name}}
</li>
{% endfor %}
</ul>

Creating Django Wagtail Sidebar with Index Page Child Links

I'm building a site using Django Wagtail and am having trouble figuring out how to add a sidebar menu that will list all the child pages of the parent index page. For example, I have a standard_index_page.html that I created a parent page with in Admin, then I added child pages of that using standard_page.html template.
In my standard_index_page.html template, I have the following code
{% standard_index_listing calling_page=self %}
and it displays all the child pages with links, but I would also like to display a list of all the child links on the child pages as well.
I hope this is making sense and someone can lend a hand. Thank you.
In essence you traverse the tree structure of your page hierarchy that is provided to Wagtail by Django-Treebeard.
Many front-end frameworks do not allow for multiple levels of menus as some consider it outside of best practices. However, with a library such as SmartMenus you can display this structure with a little elbow grease.
For my needs, there was no easy solution to this. So, while I want to share an example of how I went about this, it may be missing explanation. If you have any questions, I'd be happy to answer them.
I struggled with this for awhile and while there may be easier methods to traverse the tree, I built the following method as my needs expanded. It allows us to traverse all live pages in our site, check when the current page is being rendered in the menu, and allows for fine-grained control over rendering.
Here's what we're going to do:
Create a few template tags that will get the site root of the
current site, loop through direct children of the site root, and loop through any lower levels of children, while looping through children of the current menuitem when discovered at each level.
In your base template, this means we need to:
{% load demo_tags %} to import our custom template tags
Call {% top_menu calling_page=self %} to get and render all
direct children of the site root. These are items that would be shown across a standard menu bar.
Call {% top_menu_children parent=menuitem %} within the template
rendered by {% top_menu %} to get and render all second- and
lower-level children pages. This encompasses all menu items to be shown when hovering on the parents menu item.
Here's the custom demo_tags.py file I created to traverse all levels of the page hierarchy. The beauty of this is that it does not require any custom context data to be supplied; it works out of the box with Wagtail!
#register.assignment_tag(takes_context=True)
def get_site_root(context):
'''
Returns a core.Page, not the implementation-specific model used
so object-comparison to self will return false as objects would differ
'''
return context['request'].site.root_page
def has_menu_children(page):
'''
Returns boolean of whether children pages exist to the page supplied
'''
return page.get_children().live().in_menu().exists()
#register.inclusion_tag('info_site/tags/top_menu.html', takes_context=True)
def top_menu(context, parent, calling_page=None):
'''
Retrieves the top menu items - the immediate children of the parent page
The has_menu_children method is necessary in many cases. For example, a bootstrap menu requires
a dropdown class to be applied to a parent
'''
root = get_site_root(context)
try:
is_root_page = (root.id == calling_page.id)
except:
is_root_page = False
menuitems = parent.get_children().filter(
live=True,
show_in_menus=True
).order_by('title')
for menuitem in menuitems:
menuitem.show_dropdown = has_menu_children(menuitem)
return {
'calling_page': calling_page,
'menuitems': menuitems,
'is_root_page':is_root_page,
# required by the pageurl tag that we want to use within this template
'request': context['request'],
}
#register.inclusion_tag('my_site/tags/top_menu_children.html', takes_context=True)
def top_menu_children(context, parent, sub=False, level=0):
''' Retrieves the children of the top menu items for the drop downs '''
menuitems_children = parent.get_children().order_by('title')
menuitems_children = menuitems_children.live().in_menu()
for menuitem in menuitems_children:
menuitem.show_dropdown = has_menu_children(menuitem)
levelstr= "".join('a' for i in range(level)) # for indentation
level += 1
return {
'parent': parent,
'menuitems_children': menuitems_children,
'sub': sub,
'level':level,
'levelstr':levelstr,
# required by the pageurl tag that we want to use within this template
'request': context['request'],
}
In essence, there are three levels of pages rendered:
The site root is called by {% get_site_root %}
First-level children are called by {% top_menu %}
Second- and lower-level children are called by {% top_menu_children %}, which is called any time a page shown in the menu has children while rendering this tag.
In order to do this, we need to create the templates to be rendered by our top_menu and top_menu_children template tags.
Please note - these all are built for Bootstrap 3's navbar class and customized for my needs. Just customize these for your needs. The whole menu building process is called by {% top_menu_children %}, so place this tag in your base template where you want the menus rendered. Change top_menu.html to reflect the overall structure of the menu and how to render each menuitem. Change children_items.html to reflect how you want children of all top-menu items, at any depth, rendered.
my_site/tags/top_menu.html
{% load demo_tags wagtailcore_tags static %}
{% get_site_root as site_root %}
{# FOR TOP-LEVEL CHILDREN OF SITE ROOT; In a nav or sidebar, these are the menu items we'd generally show before hovering. #}
<div class="container">
<div class="collapse navbar-collapse" id="navbar-collapse-3">
<ul class="nav navbar-nav navbar-left">
{% for menuitem in menuitems %}
<li class="{% if menuitem.active %}active{% endif %}">
{% if menuitem.show_dropdown %}
<a href="{{ menuitem.url }}">{{ menuitem.title }}
<span class="hidden-lg hidden-md hidden-sm visible-xs-inline">
<span class="glyphicon glyphicon-chevron-right"></span>
</span>
</a>
{% top_menu_children parent=menuitem %}
{% else %}
{{ menuitem.title }}
{% endif %}
</li>
{% endfor %}
</ul>
</div>
</div>
my_site/tags/children_items.html
{% load demo_tags wagtailcore_tags %}
{# For second- and lower-level decendents of site root; These are items not shown prior to hovering on their parent menuitem, hence the separate templates (and template tags) #}
<ul class="dropdown-menu">
{% for child in menuitems_children %}
{% if child.show_dropdown %}
<li>
<a href="{% pageurl child %}">
{% for i in levelstr %}&nbsp&nbsp{% endfor %}
{{ child.title }}
<span class="glyphicon glyphicon-chevron-right"></span>
</a>
{# On the next line, we're calling the same template tag we're rendering. We only do this when there are child pages of the menu item being rendered. #}
{% top_menu_children parent=child sub=True level=level %}
{# ^^^^ SmartMenus is made to render menus with as many levels as we like. Bootstrap considers this outside of best practices and, with version 3, has deprecated the ability to do so. Best practices are made to be broken, right :] #}
</li>
{% else %}
<li>
<a href="{% pageurl child %}">
<!-- Allows for indentation based on depth of page in the site structure -->
{% for i in levelstr %}&nbsp&nbsp{% endfor %}
{{ child.title }}
</a>
</li>
{% endif %}
{% endfor %}
</ul>
Now, in your base level template (let's assume you are using one; if not, get to it :) ) you can traverse the menu while keeping clutter cleared away to the templates used by your inclusion_tags.
my_site/base.html
<ul class="nav navbar-nav navbar-left">
{% for menuitem in menuitems %}
<li class="{% if menuitem.active %}active{% endif %}">
{% if menuitem.show_dropdown %}
<a href="{{ menuitem.url }}">{{ menuitem.title }}
<span class="hidden-lg hidden-md hidden-sm visible-xs-inline">
<span class="glyphicon glyphicon-chevron-right"></span>
</span>
</a>
{% top_menu_children parent=menuitem %}
{% else %}
{{ menuitem.title }}
{% endif %}
</li>
{% endfor %}
</ul>
I wrote a blog post about this - check it out for more details. Or, head over to Thermaline.com to see it in action, though I think there's not multiple levels of depth right now. IF THERE WERE, they'd be rendered automatically :)
Now, this example is for a navbar, but it could easily be adapted for a sidebar.
All you need to do is:
Include demo_tags in your base template
Call {% top_menu %} where you wish to render your menus.
Customize top_menu.html and children_items.html to render the
first and then all subsequent levels of pages.
Shout out to Tivix for their post on two-level menus that was a great starting point for me!

How to remove a page link from Navigation menu big cartel

I'm using the Luna Theme on Big Cartel. I've added a static 'Thank you' page for signing up to the newsletter. However the link appears in the footer navigation menu. How do I remove the link from the menu?
To remove a specific page from the footer navigation in the Luna theme, you can head to Customize Design > Advanced > Layout in the admin, and click the "Custom" button to enable code editing.
Scroll down almost all the way to the bottom, and you'll see this block of code:
{% for page in pages.all %}
<li>{{ page | link_to }}</li>
{% endfor %}
To exclude a specific page, you can modify that block - if your page is titled "Thank You", this code will only display every other page:
{% for page in pages.all %}
{% if page.name != 'Thank You' %}<li>{{ page | link_to }}</li>{% endif %}
{% endfor %}

Factorizing a header menu in Django template

I'm building a website using django with a header on top of every page, which basically is a menu with a few links, constant throughout the pages.
However, depending on the page you're on I'd like to highlight the corresponding link on the menu by adding the class "active". To do so, I am currently doing as follow: each page has a full menu block that integrates within a general layout, which does NOT contain the menu. For exemple, page2 would look like this:
{% extends "layout.html" %}
{% block menu %}
<li>Home</li>
<li>page1</li>
<li class="active">page2</li>
<li>page3</li>
{% endblock %}
The problem is that, beside from that solution being not so pretty, every time I want to add a link to the header menu I have to modify each and every page I have. Since this is far from optimal, I was wondering if any of you would know about a better way of doing so.
Thanks in advance!
You can create a custom templatetag:
from django import template
from django.core.urlresolvers import reverse, NoReverseMatch, resolve
register = template.Library()
#register.simple_tag
def active(request, view_name):
url = resolve(request.path)
if url.view_name == view_name:
return 'active'
try:
uri = reverse(view_name)
except NoReverseMatch:
uri = view_name
if request.path.startswith(uri):
return 'active'
return ''
And use it in the template to recognize which page is loaded by URL
<li class="{% active request 'car_edit' %}">Edit</li>
If you have a "page" object at every view, you could compare a navigation item's slug to the object's slug
navigation.html
<ul>
{% for page in navigation %}
<li{% ifequal object.slug page.slug %} class="active"{% endifequal %}>
{{ page.title }}
</li>
{% endfor %}
</ul>
base.html
<html>
<head />
<body>
{% include "navigation.html" %}
{% block content %}
Welcome Earthling.
{% endblock %}
</body>
</html>
page.html
{% extends "base.html" %}
{% block content %}
{{ object }}
{% endblock %}
Where navigation is perhaps a context_processor variable holding all the pages, and object is the current PageDetailView object variable
Disclaimer
There are many solutions for your problem as noted by Paulo. Of course this solution assumes that every view holds a page object, a concept usually implemented by a CMS. If you have views that do not derive from the Page app you would have to inject page pretenders within the navigation (atleast holding a get_absolute_url and title attribute).
This might be a very nice learning experience, but you'll probably save loads time installing feinCMS or django-cms which both define an ApplicationContent principle also.
You may use the include tag and pass it a value which is the current page.
For example, this may be a separate file for declaring the menu template only:
menu.html
{% if active = "a" %}
<li>Home</li>
{% if active = "b" %}
<li>page1</li>
{% if active = "c" %}
<li class="active">page2</li>
{% if active = "d" %}
<li>page3</li>
And call this from within your template like this:
{% include 'path/to/menu.html' with active="b"%} # or a or c or d.
Hope it helps!
