notes
I migrated the database, and see the data in the database, and everything looks correct.
page renderings
photologue urls:
A single photo
the list of the photos
and the direct accessing of the image: (ra is the name in photologue, but em.jpeg is the file name)
and my view directly:
The template was wrong/outdated from an older version. Here is the correct usage in the template for an image within a list of images of type photologueExtended:
{% for photoExtended in photos %}
<!-- The link to the photologue template page with the photo and its gallery(s)-->
Link to page
<!-- The src link to the image thumbnail itself in the media url-->
<img src="{{ photoExtended.photo.get_thumbnail_url }}" />
<!-- The src link to the image itself in the media url-->
<img src="{{ photoExtended.photo.get_display_url }}" />
<!-- The photologue image's title/description/etc… -->
{{ photoExtended.photo.title }} <br>
{{ photoExtended.photo.description }} <br>
{% endfor %}
Also:
the url catchall in the main project urls.py was incorrect, and should be:
url(r'^$', indexView, name='indexView'),

I am not able to get the 'pizzas' page template to render. The local environment is giving me an error that says: Reverse for 'pizzas' not found. 'pizzas' is not a valid view function or pattern name. Does anyone see the issue? My code is below. Thanks!

The homepage ('pizzas/index') was rendering and inheriting properly from base.html. But when I tried adding a new pizzas page I started getting the above error message on the homepage.
i am new to react , i am building simple blog where user can post with title and body
in html its done with listview with:
{% for x in object_list %}
{% endfor %}
but in react component its not getting good result and showing error
here is my code:
models
class post(models.Model):
title = models.CharField(max_length=100)
body=models.TextField()
views
class list(ListView):
model = post
template_name = 'index.html'
post.js
function Post(){
return(
{% for x in object_list %}
{% endfor %}
)
}
in react what can i do to retreive data from model like we used to do in normal html, or show the object from model in components??
So this awesome Wagtail/Django framework is nice!
I like it allot.
Still getting used to but seems straight forward,
What I do not understand tho is how can I access default page models and render them in the templates?
So Wagtail has this models that you make based on their Page class.
class SomeClass(Page):
"""
Some text
"""
intro = models.CharField(max_length=255, blank=True)
body_small = models.CharField(max_length=255, blank=True)
All good and well.
Now my page template looks like this
{% extends "base.html" %}
{% load wagtailcore_tags %}
{% block base_content %}
{{ page.intro }}
{{ page.body_small }}
{% endblock %}
Now I want to add the settings model items like Published Date.
Those are default from Wagtail, see:
What page model do I need to use?
{{ page.published_date }} //Does not work
Any suggestions?
The fields in the Settings tab are available as {{ page.go_live_at }} and {{ page.expire_at }}. However, these are only used for scheduled publishing so may not be a particularly relevant thing to output on the page - {{ page.first_published_at }} and {{ page.last_published_at }} are probably more useful. See http://docs.wagtail.io/en/stable/reference/pages/model_reference.html for more.
I have 3 mains sections in my site, homepage, blog index, and blog specific. I am using the streamfield function in wagtail to order various sections in the homepage. One of those sections is for the latest three blog posts.
I have done this for the blog index page, but can't grab the latest blog posts in the streamfield.
My model looks like this
class CaseStudiesIndex(Page):
def casestudies(pages):
casestudies = CaseStudyPage.objects.all().order_by('-first_published_at')
return casestudies
intro = RichTextField(blank=True)
content_panels = Page.content_panels + [
FieldPanel('intro', classname="full")
]
class LatestPosts(blocks.StructBlock):
static = blocks.StaticBlock(admin_text='Latest posts: no configuration needed.',)
def casestudies(pages):
casestudies = CaseStudyPage.objects.all().order_by('-first_published_at')[:3]
return casestudies
class Meta:
icon = 'doc-full'
label = 'Latest Posts'
template = 'blocks/_latestPosts.html'
class HomePage(Page):
blocksbody = StreamField([
('lead_banner', LeadBanner()),
('latest_posts', LatestPosts()),
('team', Team())
],null=True,blank=True)
content_panels = Page.content_panels + [
StreamFieldPanel('blocksbody'),
]
In my block folder I am calling the file fine and it renders the wrapper fine but I can't grab any of the data, I have tried a bunch of ways but nothing returns.
{% load wagtailcore_tags wagtailimages_tags %}
{% load static %}
<section>
<div class="wrapper__inner">
<ul>
{% for case in self.casestudies %}
{{case.title}}
{% endfor %}
{% for case in self.case_studies %}
{{case.title}}
{% endfor %}
{% for case in self.latest_posts %}
{{case.title}}
{% endfor %}
{% for case in page.casestudies %}
{{case.title}}
{% endfor %}
{% for case in page.case_studies %}
{{case.title}}
{% endfor %}
{% for case in page.latest_posts %}
{{case.title}}
{% endfor %}
</ul>
</div>
</section>
For the Blog Index page that does work I do the following.
{% extends "inner_base.html" %}
{% load wagtailcore_tags %}
{% block body_class %}template-case-studies{% endblock %}
{% block content %}
<section>
<div class="wrapper__inner">
<h1>{{self.title}}</h1>
<ul>
{% include "blocks/CaseStudiesLatestBlock.html" %}
</ul>
</div>
</section>
{% endblock %}
And the CaseStudiesLatestBlock.html which works fine looks like
{% load wagtailcore_tags wagtailimages_tags %}
{% load static %}
{% for case in self.casestudies %}
<li>
<strong>{{ case.title }}</strong>
</li>
{% endfor %}
Defining your own methods on a StructBlock won't work - the self (or value) variable you receive on the template is just a plain dict, not the StructBlock object itself. (This might seem counter-intuitive, but it's consistent with how blocks work in general: just as a CharBlock gives you a string value to work with and not a CharBlock instance, StructBlock gives you a dict rather than a StructBlock instance.)
Instead, you can define a get_context method (as documented here) to provide additional variables to the template:
class LatestPosts(blocks.StructBlock):
static = blocks.StaticBlock(admin_text='Latest posts: no configuration needed.',)
def get_context(self, value, parent_context=None):
context = super(LatestPosts, self).get_context(value, parent_context=parent_context)
context['casestudies'] = CaseStudyPage.objects.all().order_by('-first_published_at')[:3]
return context
You can then access the casestudies variable in the template, e.g. {% for case in casestudies %}.
I am learning Django and am trying to filter names based off the database table: power_id. Is there anyway to filter based off power_id, or any variable in a database? Here is what I have so far. Note, I am using Twitter-Bootstrap
This is the Team View
<div class="accordion-inner">
<ul>
{% if User.object.power_id == 1 %}
<li>
<a href="#">
{{ user }}
</a>
</li>
{% endif %}
</ul>
</div>
Lets say, 1 is an Admin.
Here is my views.py:
# Home view
class home(generic.ListView):
template_name = 'users/home.html'
context_object_name = 'User_list'
context_object_name2 = 'Power_list'
def get_queryset(self):
return User.objects.order_by('username')
# Team view
class team(generic.ListView):
template_name = 'users/team.html'
context_object_name = 'User_list'
def get_queryset(self):
return User.objects.order_by('username')
context_object_name2 = 'Power_list'
def in_catagory(User, Admin):
return things.filter(Admin=Admin)
From what I can see, you have passed in a model that you have created called User. Now, I do not know if this is a model that you have actually created or if you are using django.contrib.auth.models.User. But, this is an attempt to show you how to work with views in django.
from django.views.generic import View
from django.shortcuts import render
from .models import User
class TeamView(View):
def get(self, request):
Users = User.objects.filter(power_id='123')
return render(request, 'something.html', {'Users': Users, })
What I've done here may look intimidating, but is actually quite simple. From what I can understand, you have a bunch of users, with an property called power_id. And you want to get that, you need to filter all your users for the users with the power_id that you want.
That is what the first line after the get function call does. the get function call is here because when you send a request to a page, like www.google.com, you are sending a get request.
Now, the render function is a shortcut function. What it does is this: first parameter is always request, the second parameter is the html file that you want it to render, and the third parameter is the information you are sending which is a dictionary.
Now coming to your template. You can simply loop through all your users, like so:
<div class="accordion-inner">
<ul>
{% for user in Users %}
<li>
<a href="#">
{{ user }}
</a>
</li>
{% endfor %}
</ul>
</div>
You can override the get_context_data method to add that other variable.
class TeamView(ListView):
template_name = 'users/team.html'
context_object_name = 'User_list'
model = User # You never set the model
def get_queryset(self):
return super('TeamView', self).get_queryset().order_by('username') # call the parent function
def get_context_data(self, *args, **kwargs):
context = super('TeamView', self).get_context_data(*args, **kwargs)
context['Power_list'] = self.get_queryset().filter(power_id=1)
return context
Now you also have a context variable Power_list with all of the users that have power_id == 1 that you can iterate over
<div class="accordion-inner">
<ul>
{% for user in Power_list %}
<li>
<a href="#">
{{ user }}
</a>
</li>
{% endfor %}
</ul>
</div>
I have found the answer to my own question. Turns out, it was much simpler than I thought it was. What I needed was to re-arrange the code, along with getting variables right.
<div class="accordion-inner">
<ul>
{% for name in User_list %}
{% if name.power_id == 1 %}
{{ name }}<br />
{% endif %}
{% endfor %}
</ul>
</div>
The views.py file didn't need to be edited at all.
