Does anyone know what I'm doing wrong? Stupid beginner mistake? Also if there's other code that may be relevant here please let me know and I can provide it.
Edited to add:
The higher level issue here is that MyModel has a field called user. When a user views the MyModel changelist, they need to only see the MyModel objects that reference them, and should not see the MyModel objects that reference other users.
First, you are using a view outside of the admin, which is fine, but you are using an admin template change_list.html which assumes some variables sent out with the template context. I would suggest to add custom urls to your admin.py (see bellow), and send the necessary context so the template is rendered properly.
I had the same issue, which was caused in this line:
<li>{{ opts.app_config.verbose_name }}</li>
When looking on the context provided to the template with django-debug-toolbar I noticed that the opts variable was not being sent. In your case, the culprit is probably cl.
So I had to update my custom urls code and sent it myself:
def get_urls(self):
urls = super().get_urls()
opts = self.model._meta
custom_urls = [
url(
r'^(?P<some_id>.+)/actions/task_start/$',
self.admin_site.admin_view(SomeCustomFormView.as_view(
extra_context={'opts': opts}
)),
name='task_start',
),
]
return custom_urls + urls
The cl variable is got from the request:
cl = self.get_changelist_instance(request) and sent out with the context like this (django/contrib/admin/options.py):
context = {
**self.admin_site.each_context(request),
'module_name': str(opts.verbose_name_plural),
'selection_note': _('0 of %(cnt)s selected') % {'cnt': len(cl.result_list)},
'selection_note_all': selection_note_all % {'total_count': cl.result_count},
'title': cl.title,
'subtitle': None,
'is_popup': cl.is_popup,
'to_field': cl.to_field,
'cl': cl,
'media': media,
'has_add_permission': self.has_add_permission(request),
'opts': cl.opts,
'action_form': action_form,
'actions_on_top': self.actions_on_top,
'actions_on_bottom': self.actions_on_bottom,
'actions_selection_counter': self.actions_selection_counter,
'preserved_filters': self.get_preserved_filters(request),
**(extra_context or {}),
}
But you don't have easy access to the request in get_urls so I would change the template code and instead of using cl I would use opts which I get from the model meta field.
I'm stuck at Django's official tutorial (see Writing your first Django app, part 4).
https://docs.djangoproject.com/en/3.1/intro/tutorial04/
I get the following error:
https://i.stack.imgur.com/7zPI9.png
In this Django project, inside the poll app I'm making, we're supposed to make a vote() view in views.py which should process the POST request data of the poll and redirect us to the results() view (there's no template for the vote()view, it's just in charge of processing the data we send through the poll). At first I thought I had a typo error, but I then copy-pasted everything directly out of the documentation tutorial (which I linked at the beginning of this question) and the error persisted.

I applied django-filter library in my project if it's not filtering the items.
if i visit the url http://127.0.0.1:8000/products/?q=&category=electronics it should gives the only electronics products but its giving the all available products. What i am doing wrong? it should filter categories wise or product title wiase and price wise.
class ProductFilter(FilterSet): # by using django-filters
title = CharFilter(field_name='title', lookup_expr='icontains', distinct=True)
category = CharFilter(field_name='categories__title', lookup_expr='icontains', distinct=True)
category_id = CharFilter(field_name='categories__id', lookup_expr='icontains', distinct=True)
min_price = NumberFilter(field_name='price', lookup_expr='gte', distinct=True)
max_price = NumberFilter(field_name='price', lookup_expr='lte', distinct=True)
class Meta:
model = Product
fields = ['category', 'title', 'description', 'min_price', 'max_price']
class FilterMixin(object):
filter_class = ProductFilter
search_ordering_param = 'ordering'
def get_queryset(self, *args, **kwargs):

Your FilterMixin never exports something like a product_list, so that will be the original queryset, not the one that you filter with the FilterSet.
You can easily update this with:
def get_context_data(self, *args, **kwargs):
context = super().get_context_data(*args, **kwargs)
qs = context['object_list']
if self.filter_class:
qs = self.filter_class(self.request.GET, queryset=qs).qs
ordering = self.request.GET.get(self.search_ordering_param)
if ordering:
qs = qs.order_by(ordering)
context['object_list'] = qs
context_object_name = self.get_context_object_name(qs)
if context_object_name is not None:
context[context_object_name] = qs
return context
I am using template tags to present data that has been derived from class objects on the back end. Both class objects require inputs from the user to work and if the input is not valid they return None.
I need to present a difference calculation of two of the objects on the page (it does not need to be saved to the database). So I have installed mathfilters https://pypi.python.org/pypi/django-mathfilters to do the subtraction which worked if there is user input but does not work if I am just navigating to the page or no user input.
Template HTML:
<tr>
<td>Interest</td>
<td class="data">${{int_numbers.get_sum_int_daily_numbers | intcomma }}</td>
<td class="data">${{int_goals.get_div_goalsint_wdays | intcomma }}</td>
<td class="data"><font class="red">
${{ int_numbers.get_sum_int_daily_numbers|sub:int_goals.get_div_goalsint_wdays | intcomma }}
</font>
</td>
</tr>
Which gives me this error:

I tried this filter:

<td class="data">${{int_goals.get_div_goalsint_wdays | intcomma }}</td>
<td class="data"><font class="red">
{% if int_numbers.get_sum_int_daily_numbers|sub:int_goals.get_div_goalsint_wdays is "None" %}
0
{% else %}
${{ int_numbers.get_sum_int_daily_numbers|sub:int_goals.get_div_goalsint_wdays | intcomma }}
{% endif %}
</font>
</td>
</tr>
Received the same error.
Is there a way with template tags and filters to correct this issue?
Seems that "int_goals" is undefined, thus None. If you try to do a math operation on
int_numbers.get_sum_int_daily_numbers - None.get_div_goalsint_wdays python will throw an exception
Hi Stack overflow people:
I would lithe to receive some orientation in this following newbie python Error
I have two model forms in my forms.py:
class StrategicDnaValuePropositionForm(forms.ModelForm):
title = "Adn Estratégico y Propuesta de valor"
class Meta:
widgets = {
'familiar_enterprise':forms.RadioSelect,
'enterprise_concepts':forms.RadioSelect,
'value_purpose_target':forms.RadioSelect,
'competition_differentiation':forms.RadioSelect,
'goals_objectives':forms.RadioSelect,
'avoid_competition':forms.RadioSelect,
'enterprise_strategy':forms.RadioSelect,
}
model = StrategicDnaValueProposition
fields = ('familiar_enterprise', 'enterprise_size',
'enterprise_concepts', 'value_purpose_target', 'competition_differentiation', 'goals_objectives',
'avoid_competition')
class MarketingSalesForm(forms.ModelForm):
title = "Mercadeo y Ventas"
class Meta:
widgets = {
'key_activities':forms.RadioSelect,
'new_clients_strategies':forms.RadioSelect,
}
model = MarketingSales
fields = ('key_activities', 'new_clients_strategies',)
In my view, I would like to generate two forms instances of these model forms and send to the template to save them.
My views.py:
#login_required
def diagnostic_tool_questions(request):
user = request.user
# Populate the forms
form_diagnostic = []
if user.is_enterprise:
profile = user.get_enterprise_profile()
form_diagnostic.append({
'form_strategicdna': StrategicDnaValuePropositionForm,
'form_marketing_sales': MarketingSalesForm,
'instance': user.enterpriseprofile,
})
if request.method == 'POST':
# forms = [x['form'](data=request.POST,) for x in form_diagnostic]
forms = [x['form'](data=request.POST, instance=x['instance'],) for x in form_diagnostic]
if all([form.is_valid() for form in forms]):
for form in forms:
form.save()
return redirect('dashboard')
else:
forms = [x['form'](instance=x['instance']) for x in form_diagnostic]
return render(
request, 'enterprise_process/strategicdnavalueproposition_form.html',
{'forms':forms, 'userprofile':profile,})
My template is:
{% extends 'layout.html' %}
{% load bootstrap3 %}
{% block title_tag %}Herramienta de Diagnóstico | CRIMBLU {{ block.super }}{% endblock %}
{% block body_content %}
<div class="container">
<h1>Account Details</h1>
<form method="POST">
{% csrf_token %}
{% for form in forms %}
{% bootstrap_form form %}
{% endfor %}
<input type="submit" value="Save Changes" class="btn btn-default">
</form>
</div>
{% endblock %}
When I go to the url which call to my diagnostic_tool_questions view I get the following message:
System check identified no issues (0 silenced).
