Django going to external website with my variables in url - django

I have a model and i want to go to a external website with my variables in the url . For example: "www.example.com\ {% object.field %} .com
My model
class Avaria(models.Model):
freguesia = models.ForeignKey(Freguesia, on_delete=models.CASCADE,verbose_name="Freguesia")
rua = models.ForeignKey(Rua, on_delete=models.CASCADE,verbose_name="Rua")
I'm changing my change_form_object_tools.html and add a extra li to do something like this:
<li>
{% trans "Example" %
</li>
If i use the original.pk it is working but i want to use another field that is not the primary key

If you're getting correct object in variable obj then
instead of
{% trans "Example" %
you need to do
{% trans "Example" %
I know in django admin model object comes in variable original, you can use original in place of obj.
Also if you want to understand django template language
{{ }} for rendering variables and using filters, read more
{% %} for sentences such as if and for or to call tags such as load, static, etc. is for tags, read more
Similarly there is {# #} for comments.
Read the documentation please

Additional field shows up outside table in admin change_list view

I have a model called Project in an app called projects that I registered with the admin site so the instances can be added/edited/etc. This works as expected. Now I want to add a button for each project in the change list view on the admin site, that links to a custom form that requires a Project instance to do things. I followed a bunch of different tutorials to customize the admin site and managed to add another field to the table of the change list view. However the entries show up outside the table (see image).
I added the custom field by overwriting the admin/change_list.html template and calling a custom template tag custom_result_list within it. This tag adds a table field to the change list and then calls the admin/change_list_results.html template to render it. I have confirmed with a debugger that the item is added to the entries of the change list before the template is rendered (see image).
I cannot explain why the table is not rendered correctly even though the additional field has the same structure as the auto-generated ones. I have to admit I have resorted to Cargo Cult Programming, because I do not understand how this is supposed to work, despite spending too many hours trying to solve this simple problem.
Here's the relevant code.
In file /projects/templatetags/custom_admin_tags.py:
from django import template
from django.contrib.admin.templatetags.admin_list import result_list as admin_result_list
def custom_result_list(chl):
extended_cl = {}
extended_cl.update(admin_result_list(chl))
extended_cl["result_headers"].append({
'class_attrib': r' class="column-__str__"',
'sortable': False,
'text': 'Configure Project'
})
idx = 0
snippet = '<td class="action-button">{}</td>'
for project in chl.result_list:
extended_cl["results"][idx].append(snippet.format(project.id, project.unmod_name))
idx += 1
return extended_cl
register = template.Library()
register.inclusion_tag('admin/change_list_results.html')(custom_result_list)
In file templates/admin/projects/project/change_list.html:
{% extends "admin/change_list.html" %}
{% load i18n admin_urls static admin_list %}
{% load custom_admin_tags %}
{% block result_list %}
{% if action_form and actions_on_top and cl.show_admin_actions %}{% admin_actions %}{% endif %}
{% custom_result_list cl %}
{% if action_form and actions_on_bottom and cl.show_admin_actions %}{% admin_actions %}{% endif %}
{% endblock %}
To fix your issue:
from django.utils.html import format_html
replace your snippet.format(...) with format_html(snippet,...)
Explanation:
in django, all strings you pass from python are automatically HTML escaped. which here means, all your tags will not be considered as HTML. Such limitation is added to avoid any potential exploits by hackers. In your case, use of a template to render html is highly recommended. However, you can also send raw html from python using format_html helper function.

How do I call my dict parameters from the view.py render in my template?

I have been working on this for two day, and have read almost every example on stackoverflow and consulted the django documentation. I am trying to pass my dict from the views.py to my template, but I keep getting the stupid "Could not parse the remainder" error. I'm not doing anything fancy. Just Href buttons passing in a parameter to represent what that button is. Then a template page opens using that parameter as a string to make the new page and url unique.
pass in with:
Call
urls.py
urlpatterns = [
url(r'^call=(\d+)/$', views.call, name='call')
]
views.py
def call(request, callID):
call_id = { 'id':callID }
return render(request, 'site/call.html', call_id)
Call template
{% extends 'site/layout.html' %}
{% block content %}
{% with call_id.get('id') as view_id %}
<h3 class="center-align blue lighten-3">Site # Room {{ view_id }}</h3>
Cancel
{% endwith %}
{% endblock %}
I have tried request.GET.get('id') and a bizillion other things. Can someone show me how I can actually parse those dict values I passed in?
You're not actually passing a dictionary at all. You're passing a single value, id, so you should just use that. And there is no need for any with block.
Site # Room {{ id }}

Django: how to get a model instance by id within a template

Just a quick question - I was wondering if it were possible to return a model instance by id within a template e.g.,
If I had a list of comments associated to posts by the post Id, and did something like:
{% for comment in comments %}
{{ request.post.get_by_id(id == comment.object_id).title }}
{% endfor %}
I'm working within a tags.py "pseudo-view" using the following:
#register.inclusion_tag('blog/frame/latest_comments.html')
def show_latest_comments(count=5):
latest_comments = Comment.objects.all()[:count]
return { 'latest_comments': latest_comments}
Should I work within the tags.py file to maybe loop over the latest_comments object and extract everything I need, including the blog post it is associated to and then dump this in the context as a new dictionary...?

Object field in {% url %}

Is it possible to insert into {% url %} field from queryset record?
e. g.
{% url queryset[0].field %}
I viewed django source and reach the conclusion that what I want to do is not possible, so I made it other way. In view for every record from query set I added new field url:
for q in queryset:
q.url = reverse(q.field_with_url_name)
I think the simplest way
Of course it's possible, but square brackets are not valid syntax anywhere in Django's templating language. This is very clearly documented.
This would work:
{% url queryset.0.field %}

Displaying page content using django-page-cms

I would like to display some content located in my models in some of my template pages.
I am using django-page cms
In the documentation views are not used to display content. Instead ready made template tags are used.
http://packages.python.org/django-page-cms/display-content.html
I do not understand a word of this. Please Bear with me I am new.
All I want to do is display some info located in my models inside a template this manner..
{% if latest_news_list %}
{% for news in latest_news_list %}
<li><h3>{{ news.title }}</h3></li>
<li><p>{{ news.body }}</p></li>
{% endfor %}
Since views are not used I cannot use if latest_news_list.
I need to somehow get my models to display in the templates using django-page cms and NOT regular views. The documentation states to use some kind of template tag for this.
Could somebody please explain to me how to do this.
And a clear concise explanation of the following ready-made template tags would also be appreciated...
* get_content
* show_content
* get_page
* show_absolute_url
taken from.http://packages.python.org/django-page-cms/display-content.html
I need to display info contained using the following models in the manner I have highlighted above. Thank you very much for your help. my models are as follows.
class Body(models.Model):
type = models.ForeignKey(Content)
title = models.CharField(max_length=100)
published = models.DateTimeField(default=datetime.now)
body = tinymce_models.HTMLField("Main content")
As I have stated I am very new to this please make explanations as simple as possible.
The template tags you mentioned are supposed to display content coming from the cms. If you want to include data coming from your app, you should see this sectionlink text.
def extra_context():
from myapp.models import Body
items = Body.object.all()
return {'items': items}
PAGE_EXTRA_CONTEXT = extra_context
{% if items %}
<ul>
{% for item in items %}
<li>{{ item.title }} </li>
{% endfor %}
<ul>
{% endif %}
Or, if you want to use your app's view, see this.
