I want to try and show or hide urls in my navigation page based on user group.
currently i am adding to the top of every view and sending through a value to the template and checking against that, but this doesnt seem too efficient, also if a view does not require auth and that value is not set, will that break the template?
is there a better way to do this?
like a global.py where i could check and set then use it in any template? or something completely different altogether?
view.py
Authorised_user = ''
if request.user.is_authenticated():
Authorised_user = 'IT'
#login_required
def index(request):
return render(request, 'service/index.html', {
'Authorised': Authorised_user,
})
template.html
{% if Authorised == 'IT' or Authorised =='Netwworks' %}
Link
{% endif %}
i do have the user groups in django admin
Based on Get user group in a template
Create user_tags.py / group_tags.py at an appropriate place. e.g. auth_extra/templatetags/user_tags.py
from django import template
register = template.Library()
#register.filter('in_group')
def in_group(user, group_name):
return user.groups.filter(name=group_name).exists()
Then in your template:
{% load user_tags %}
{% if request.user|in_group:"IT"%}
IT only link
{% endif %}
{% if request.user|in_group:"Netwworks"%}
Netwworks only link
{% endif %}
Easiest way around this for me was https://stackoverflow.com/a/17087532/8326187.
Here you don't have to create a custom template tag.
{% if request.user.groups.all.0.name == "groupname" %}
...
{% endif %}
You need to create context_processors.py and create a function say
def foo():
Authorised_user = ''
if request.user.is_authenticated():
Authorised_user = 'IT'
Then in setttings
TEMPLATE_CONTEXT_PROCESSORS = ("path_to_context_processor.foo")
this way you can use foo variable in all the templates without explicitly defining in all the views.
You can also have a look here:https://rubayeet.wordpress.com/2009/10/31/django-how-to-make-a-variable-available-in-all-templates/

I am not able to use the Django model object in Django templates. I want to iterate using the model user in the template and then play with the ActivityPeriod(model) of that user. Please check my code for the clarity:
Here is my code:
views.py
from .models import User,ActivityPeriod
def call_response(request):
user = User.objects.all()
return render(request, "Test/list.html", {"users":user ,"activityperiod":ActivityPeriod})
Test/list.html
{% for user in users %}
'real_name': {{ user.real_name}}},
'activity_periods': {% with activity=activityperiod.objects.get(id =user) %}
{{ activity.start_time }}
{% endwith %}
{% endfor %}
But i am getting an error:
Could not parse the remainder: '(id' from 'activityperiod.objects.get(id'
What is the correct way? Can anyone please share it with me.
Django template don't understand the filter action of Model. This part shoud be in view.
activity=activityperiod.objects.get(id =user)
You should prepare your data and manipulate them before sending to template (a dictionary may help you). And remember that result of action "User.objects.all()" is a list.
views.py
def call_response(request):
user = User.objects.filter(user=request.user)
activityperiod = activityperiod.objects.get(user=user)
context={'user':user,'activityperiod':activityperiod}
return render(request, "Test/list.html",context})
Test/list.html
'real_name': {{ user.real_name}}
'activity_periods':{{ activityperiod.start_time }}
Your question suggests that you think you can a function in the templates like a normal function (ie activityperiod.objects.get(...)).
You can't, the templating system is not made like this (for security reasons amongst others).
You should do something like, in your models:
def call_response(request):
# ! first() not "all()" (if > 1 user, you'll have problem)!
user = User.objects.first()
activityperiod = activityperiod.objects.get(user=user)
return render(request, "Test/list.html",
{"users":user ,"activityperiod":activityperiod})
I'm creating a django blog app where users can add comments to articles.
I want to remove the post button when the user has already commented.
I have a model named article and another one named comment (with ForeignKey to article)
I tried {% if any request.user in article.comment_set.all} but that doesn't work. I tried to loop over article.comment_set.all but that didn't work either.
Is there a method to do this in the template?
Rather than doing that in template, why don't you do that in view and send it via context. For example:
def view(request):
...
user_exists = article.comment_set.filter(user=request.user).exists()
context = {}
context['user_exists'] = user_exists
return render(request, 'template.html', context)
in template:
{% if user_exists %}
// do something
{% else %}
// do something else
{% endif %}
HI Tried with template tag
register = template.Library()
#register.simple_tag(takes_context=True)
def get_all_pages(context):
context['all_page'] = Page.objects.live()
return context
and in my template
{% get_all_pages as queries %}
{% for each in queries %}
{{each.page_title}}
{% endfor %}
All pages are not passed in my templates , i want to add all pages in footer please help
I can see two problems here:
As neverwalkaloner says, a simple_tag should return the value you want to output or assign, rather than updating the context dict:
#register.simple_tag(takes_context=True)
def get_all_pages(context):
return Page.objects.live()
page_title is not a recognised property of a page object - it should be title:
{{ each.title }}
Is there any way to add form (for example feedback form) to every page in CMS? I really like to use Wagtail FormBuilder so Editor guy can change fields.
My first idea is to create custom form page (inherited from AbstractEmailForm) as site root child and load it to base.html trough template tag. I can access page properties this way but I cant render the form.
Here is my template tag:
#register.assignment_tag(takes_context=True)
def get_feedback_form(context):
return context['request'].site.root_page.get_children().type(FeedbackFormPage).first()
And this is how I use it from base.html:
{% get_feedback_form as feedback_form %}
...
{{ feedback_form.specific.title }} <-- this works
{{ feedback_form.specific.form.as_p }} <-- this doesnt work
It would be nice somehow to create a form as snippet or add it to Site Settings, but I didnt find how to do that.
The main issue is how you are generating the form in the template with .form.as_p.
You will need to generate the form with the .get_form function, but you are best to do it within your template as the current user and page needs to be past in as arguments like this.
form = feedback_form_page.get_form(
page=feedback_form_page, user=request.user)
You can see how the form is built for the AbstractForm model here:
https://github.com/wagtail/wagtail/blob/master/wagtail/wagtailforms/models.py#L278
Full detailed example below, along with how you could work the form selection into the Site Settings module.
Link to a Form in Site Settings
Assuming you are referring to the Site Settings contrib module:
http://docs.wagtail.io/en/v1.13/reference/contrib/settings.html
The 'Edit Handlers' section of the documentation explains a great way to link to a page inside of your site settings.
http://docs.wagtail.io/en/v1.13/reference/contrib/settings.html?highlight=site%20settings#edit-handlers
Example (in models.py):
from wagtail.contrib.settings.models import BaseSetting, register_setting
# ...
#register_setting
class MyCustomSettings(BaseSetting):
feedback_form_page = models.ForeignKey(
'wagtailcore.Page', null=True, on_delete=models.SET_NULL)
panels = [
# note the page type declared within the pagechooserpanel
PageChooserPanel('feedback_form_page', ['base.FormPage']),
]
Once you set this model up, you will need to do makemigration and migrate for the changes to work in admin. You will then see inside the settings menu a sub-menu titled 'My Custom Settings'
Adding linked Form to every page
Add a block (so it can be overridden in templates) that has an include in your base template (eg. myapp/templates/base.html).
<!-- Footer -->
<footer>
{% block feedback_form %}{% include "includes/feedback_form.html" %}{% endblock feedback_form %}
{% include "includes/footer.html" %}
</footer>
Create an include template (eg. myapp/templates/includes/feedback_form.html)
{% load feedback_form_tags wagtailcore_tags %}
{% get_feedback_form as feedback_form %}
<form action="{% pageurl feedback_form.page %}" method="POST" role="form">
<h3>{{ feedback_form.page.title}}</h3>
{% csrf_token %}
{{ feedback_form.form.as_p }}
<input type="submit">
</form>
Build a Template Tag to get the form and page
Your template tag needs to build the form with the page's self.get_form() function. Eg. you your template tag (base/templatetags/feedback_form)
from django import template
from myapp.models import MyCustomSettings
register = template.Library()
# https://docs.djangoproject.com/en/1.9/howto/custom-template-tags/
#register.assignment_tag(takes_context=True)
def get_feedback_form(context):
request = context['request']
my_custom_settings = MyCustomSettings.for_site(request.site)
feedback_form_page = my_custom_settings.feedback_form_page.specific
form = feedback_form_page.get_form(
page=feedback_form_page, user=request.user)
return {'page': feedback_form_page, 'form': form}
This still works in wagtail 2.3 just need to replace
#register.assignment_tag(takes_context=True)
with
#register.simple_tag(takes_context=True) to conform with django 2.2
Also {% load feedback_form_tags wagtailcore_tags %} assumes your file inside of templates tags is named feedback_form_tags.py. I also added an __init__.py in the template tags folder although I'm not sure that was actually necessary.
I want to pass data from models to template using CMS_plugins.py
I've made an app and standalone works. When i open link manualy
localhost:port/en/post_list.html all values are shown and works.
If i go on admin page and add plugin, values in mysql are stored but not presended in my template.html . I want to pass values in template.html
EDIT:
I manage to pass values to template. I edited cms_plugins.py
How can i hook data with "for" ?.
In code blow, nothing isnt shown in my template.html
<p>{{instance.firstline}}</p> ->>>this works
{ %block content %}
{{ instance.post.offer_option}}
<p>{{post.firstline}}</p>
<p>{{post.secline}}</p>
{% endfor %}
{% endblock}
if i change to :
{% for post in posts %}
<p>{{post.firstline}}</p>
<p>{{post.secline}}</p>
{% endfor %}
{% endblock}
In upper case if i run manualy url: localhost:port/en/pricing , I can see the result i want to be rendered in template.In template nothing isnt shown neither.
cms_plugins.py
class pricing(CMSPluginBase):
model = Post
name = _("pricing")
render_template = "post_list.html"
cache = False
def render(self, context, instance, placeholder):
context.update({'instance': instance})
return context
plugin_pool.register_plugin(pricing)
