Rendering MPTT structure with open/close possibility in django template
I need to render my MPTT model as tree with dropdown (open/close every node that contains children) possibility and buttons that will open/close all the nodes in that tree in 1 click. I tried to find some ready-to-use examples, but best that I found is this: <ul class="navbar-nav mr-auto"> {% recursetree thecategories %} {% if node.level == 0 %} {% if not node.is_leaf_node %} <!-- Let op: <li> tag wordt steeds onderaan aangevuld, ander werkt het niet...--> <li class="dropdown nav-item"> <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false"> <span class="mainBarItem">{{ node.ctg_Title }}<span class="caret"></span> </span></a> {% else %} <li><a href="#" class="mainBarItem">{{ node.ctg_Title }}</a> {% endif %} {% else %} {% if not node.is_leaf_node %} <li class="dropdown-submenu"> <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false"> <span class="nav-label">{{ node.ctg_Title }}<span class="caret"></span></span></a> {% else %} <li><a href="#">{{ node.ctg_Title }}</a> {% endif %} {% endif %} {% if not node.is_leaf_node %} <ul class="children dropdown-menu"> {{ children }} </ul> {% endif %} </li> {% endrecursetree %} </ul> with some CSS and JS, but it is not that I need. Actually I need to render just one tree at a time. I'm passing variable {{ product }} in my template that is just a root node. And for now … -

Create & Return Token in Serializer
Currently having difficulties returning a token in my registration view. How Can I fix this so that UserSerializer's create can return a token and username?

Django login error when using incorrect username and password on AWS
I've spent many hours trying to solve this error but I'm stuck.

Django Insert With UUID Foreign Keys Issue
I've been building a Django model using UUIDs as foreign keys. When I try to perform an insert the foreign key constraint kicks in stating that the key doesn't exist in the table, which is not true. If I take the query that is trying to be executed from the Django logs it runs fine in my SQL client. I'm using Django 3.1 with Postgresql 12.4 and trying to run the insert via mutation thru Graphene-Django. The model I'm inserting into is: class Inventory(models.Model): class Meta: db_table = "inventory" id = models.UUIDField(db_column='inventory_id', primary_key=True, default=uuid.uuid4()) item = models.CharField(db_column="inventory_item", null=False, max_length=750) quantity = models.FloatField(db_column="inventory_quantity", null=False) org_id = models.ForeignKey("org.Organization", db_column="organization_id", null=False, on_delete=models.CASCADE) unit_of_measure = models.ForeignKey("InventoryUnitOfMeasure", db_column="inventory_uom", null=False, on_delete=models.CASCADE) The query that Django is executing is: INSERT INTO "inventory" ("inventory_id", "inventory_item", "inventory_quantity", "organization_id", "inventory_uom") VALUES ('453b5dd5-1a9c-462f-adff-c93274e45cfe'::uuid, 'test string', 2000.0, 'f119b93a-d3e1-4f2a-8187-0d3f0ff8d148'::uuid, 'cec0c6e1-a0cc-4b38-b4d8-2c00367b9a01'::uuid); Running that query via SQL client works fine, but the error I receive is: insert or update on table "inventory" violates foreign key constraint "inventory_organization_id_7514cdb8_fk_organizat"\nDETAIL: Key (organization_id)=(f119b93a-d3e1-4f2a-8187-0d3f0ff8d148) is not present in table "organization" That key is in the organization table. If the query wasn't running in my SQL client I'd suspect that it's something around translating the UUID string value, but I'm out … -

manage.py makemessages doesn't work for project's urls.py file
I am running manage.py makemessages --ignore=venv/* -l fr which seems to be running correctly. Every gettext() call is present in the generated django.po files except the main urls.py file's, therefore showing only the English versions of the URLs. Other urls.py files' (within apps) gettext() calls are successfully found and present in django.po files.

Django Form - Why is the django Multiselect widget used in Admin page rendering in the same line as another field?
In my Django project, I have a form that looks like this: class SpecificPriceForm(forms.ModelForm): tanks = forms.ModelMultipleChoiceField(queryset=AutoTank.objects.all(), widget=FilteredSelectMultiple(verbose_name='Tanques', is_stacked=False)) price = forms.FloatField(label='Precio', required=True, min_value=0.0, max_value=100000.0, widget=forms.TextInput(attrs={'type': 'number'})) initial_date = forms.DateField(widget=DateInput( attrs={'class': 'form-control', 'value': datetime.datetime.now().date()}), label="Fecha inicial") final_date = forms.DateField(widget=DateInput( attrs={'class': 'form-control', 'value': datetime.datetime.now().date() + datetime.timedelta(days=7)}), label="Fecha final") class Media: css = { 'all': ('/static/admin/css/widgets.css',), } js = ('/admin/jsi18n',) class Meta: model = SpecificPrice fields = ('tanks', 'price', 'initial_date', 'final_date',) def __init__(self, *args, **kwargs): warehouse_type = kwargs.pop('warehouse_type', None) super(SpecificPriceForm, self).__init__(*args, **kwargs) if warehouse_type == 1: self.fields['tanks'].queryset = Station.objects.all() The problem is that in my view, such form displays like this: I don't know why that field is displayed there, and not under the MultiSelect field. It happens when I just include the form as {{ form|crispy }}, and it keeps happening now that I tried to render the fields individually and in different divs, ,with this code: {% block form %} <div class="form-group" style="display: block"> {{ form.media }} {{ form.tanks }} </div> <div class="form-group" style="display: block"> {{ form.price }} {{ form.initial_date }} {{ form.final_date }} </div> {# {{ form|crispy }}#} {% endblock %} Do you know why would be making in render like that? -

Filtering accounts from two different OUs in django-python3-ldap
We have a django project, where users get to login using their local AD access using django-python3-ldap. This has worked fine, since we have been using only one OU until now. However, we now need to get users from other OU, which is at the same level as the current OU. How can we do this? We have setup following: settings.py # The LDAP search base for looking up users. LDAP_AUTH_SEARCH_BASE = 'DC=ypn,DC=local' # Custom setting LDAP_AUTH_FORMAT_SEARCH_FILTERS = 'project.ldap.custom_format_search_filters' ldap.py: from django_python3_ldap.utils import format_search_filters def custom_format_search_filters(ldap_fields): # Call the base format callable. search_filters = format_search_filters(ldap_fields) # Advanced: apply custom LDAP filter logic. search_filters.append('(|(OU=office1)(OU=office2))') # All done! return search_filters And when we run python .\manage.py ldap_sync_users, it just gives us nothing. I know the filtering works, because I can search by names, for example (sn=name), and it will give me correct results. Running search without any filters just results on lots of "junk" accounts, people that have left, computers, etc. and we don't want to bring all that junk onboard. -
How do you get queryset objects related to queryset passed to templates in Django

How to save and use timezones in Django
I have an important question. I understand Django saves data in "localtime", that is, UTC for my international app. So, if a user creates an "Event" with startdate (datetime object) 18:00, it will be 18:00 UTC. However, the user lives in Spain (UTC+1), so I store the timezone ("Europe/Madrid") in a different field. When I render it in the html, it will show the UTC time (but the user lives in UTC+1). Then, if I want to convert the time to a visiting user from Spain, I use the timezone tag to convert the datetime to Spain ... and now it will show 17:00. {% if logged_user_profile.timezone %} {% timezone logged_user_profile.timezone %} <p class="text-muted font-weight-bold"> {{ event.date_start|date:"h:i A" }} ({{ logged_user_profile.timezone }} </p> {% endtimezone %} {% else %} <p class="text-muted font-weight-bold"> {{ event.date_start|date:"h:i A" }} ({{ owner_profile.timezone }}) </p> {% endif %} The Spain case is only an example. I guess my question is broad, which is the best way to deal with timezones in django. I need to store the datetime of an event and show it to visiting users in their localtime, if the stored datetime is in UTC, it will not reflect the datetime the user … -

Displaying Data from 2nd Table into 1st Table automatically as Pre-Filled for SuperAdmin (Foreignkey)
Using Django, i have 2 Tables. 1 Table is for the list of questions that User answers, the user would enter numbers. The 2nd Table is for the total Calculation, it simply just shows the total calculated number. I want to show the Total Calculated Number also in the 1st Table. So i have created a Foreign Key to do this. I have placed the Foreign Key inside the 1st Table. But when the User answers and submit the form, when i got to the 1st Table, the foreign key column/row is blank. It is forcing me as the SuperAdmin to open up the entry in the table, and manually select the value for the foreignkey. Also it is not showing in the interface of the table value of Total Calculated Number, it is just showing the 2nd table which is a class and entry number. first picture below displays the two tables in the super admin side, 1st table-"ansquestionss" 2nd table -"resultss" 2nd picture below shows after opening the 1st table "ansquetionss", you can see the foreign key column, which as the column "Results" is blank.
