Minimise code repetition by creating a reusable template
I have a template which includes 4 different paginators that only differ in context variables (tasks_today, tasks_tomorrow, ... etc.), and I want to minimise code repetition so I don't have 4 different paginator templates. Template: <div class="wrapper"> <h3>Today</h3> <table> {% if tasks_today %} {% for task in tasks_today %} {% include 'todo/task_table_row.html' %} {% endfor %} {% include 'todo/paginator_today.html' %} {% else %} <p>No tasks for today.</p> {% endif %} </table> <h3>Tomorrow</h3> <table> {% if tasks_tomorrow %} {% for task in tasks_tomorrow %} {% include 'todo/task_table_row.html' %} {% endfor %} {% include 'todo/paginator_tomorrow.html' %} {% else %} <p>No tasks for tomorrow.</p> {% endif %} </table> <h3>Upcoming</h3> <table> {% if tasks_upcoming %} {% for task in tasks_upcoming %} {% include 'todo/task_table_row.html' %} {% endfor %} {% include 'todo/paginator_upcoming.html' %} {% else %} <p>No upcoming tasks.</p> {% endif %} </table> <h3>Past</h3> <table> {% if tasks_past %} {% for task in tasks_past %} {% include 'todo/task_table_row.html' %} {% endfor %} {% include 'todo/paginator_past.html' %} {% else %} <p>No tasks in the past.</p> {% endif %} </table> </div> paginator_*: {% load url_replace %} {% if tasks_today %} <div class='paginator'> <nav aria-label="Page navigation"> <ul class="pagination"> {% if tasks_today.has_previous %} <li class="page-item"> <a class="page-link" href="?{% url_replace … -
How to POST an empty ForeignKey field in Django?
I'm fairly new to this. I have an app that is basically a check in/check out form. The form has 3 fields, two of which are required and one that is optional. One of the required fields in an "Area" and the only field that is not required is the "Station" because not every area has a station, so sometimes there will be no option to choose from station. It currently works fine if you fill out all 3 fields, but not if the station is empty, even if the area doesn't have a station. I get this error: ValueError: invalid literal for int() with base 10: '' I'm pretty sure the problem lies in my views.py, in one of my if statements for both the enter/leave because it happens on both actions, but I'm not sure what exactly it could be. The point of those if statements is that: If a person entered an area and forgot to leave and then entered another area, the program would create a new entry and not touch the previous area entry after the person leaves the new area (a person can enter and leave same area/station multiple times), so when they leave … -
Need to keep selected option with if conditional on template
I've a list of options in my template. I need to keep selected month after the "Buscar" button is pressed and has returnd the correct value. I've heard that forms in Django keep the last selected option automatically, but mine doesn't. <form method="get" action="{% url 'order:ingresos' %}"> <div class="input-group"> <div class="input-group-prepend"> <label class="input-group-text" for="inputGroupSelect01">Mes</label> </div> <select class="custom-select" searchable="Search here.." value={{filtromes}} name="filtromes"> <option value="0" disabled>Elegir mes</option> <option value="1">Enero</option> <option value="2">Febrero</option> <option value="3">Marzo</option> <option value="4">Abril</option> <option value="5">Mayo</option> <option value="6">Junio</option> <option value="7">Julio</option> <option value="8">Agosto</option> <option value="9">Setiembre</option> <option value="10">Octubre</option> <option value="11">Noviembre</option> <option value="12">Diciembre</option> </select> <div class="input-group-append"> <input class="btn btn-outline-secondary" type="submit" name="buscar" value="Buscar" style="margin-bottom: 0px;" /> </div> </div> </form> I've search and found that I can return the value of the selected option and do a if condition to find what option was selected and add the selected attribute to it, like this: <option value="0" disabled>Elegir mes</option> <option value="1" {% if filtromes == "1" %}selected{% endif %} >Enero</option> <option value="2" {% if filtromes == "2" %}selected{% endif %} >Febrero</option> But now I'm getting this error: TypeError at /ordenes/ingresos float() argument must be a string or a number, not 'NoneType' ... revenue = float(revenue['revenue']) #necessary to properly render in template / not as Decimal views.py: from … -

Post data has form input but Django modelform is not saving it
I've looked through a bunch of the other posts - but I can't find anything quite fitting to my scenario. I've got a bit of data that is coming across in the POST but then when I save the form - the data is not appearing in the database. I'm a bit perplexed as to why this is and I've tried various things, but none of them really seem to apply to my situation. Most have to do with the data not being posted, my data is posted, it's just not saving. I've got the following model: class Payment(models.Model): METHODS = ( ("Cash", "Cash"), ("Check", "Check"), ("Credit Card", "Credit Card") ) amount = models.DecimalField(decimal_places=2, max_digits=6) method = models.CharField( max_length=15, choices=METHODS, default="Credit Card" ) stripe_id = models.CharField(max_length=255, blank=True, null=True) check_number = models.IntegerField(blank=True, null=True) created_at = models.DateTimeField(auto_now_add=True) Here is my PaymentForm: class PaymentForm(forms.ModelForm): method = forms.CharField( max_length=25, widget=forms.TextInput(attrs={ "class": "form-control", "readonly": "True", }) ) amount = forms.DecimalField( decimal_places=2, max_digits=6, widget=forms.TextInput(attrs={ "class": "form-control", "readonly": "True", }) ) stripe_id = forms.CharField( widget=forms.HiddenInput(), required=False ) check_number = forms.IntegerField( widget=forms.TextInput(attrs={"class": "form-control"}), required=False ) class Meta: model = Payment fields = ( 'amount', 'method', 'stripe_id', 'check_number', ) def clean_check_number(self): method = self.cleaned_data["method"] check_number = self.cleaned_data["check_number"] if method … -

In Python, how can I convert a Docx to a PDF or Image and a PDF to an Image without using ghostscript or ImageMagick?
So, I have a use case for needing to convert documents that come in different formats (docx and pdf) and I need to convert them to an image. I have looked into PDF2Image, WAND, and PYMUPDF. I've also searched all over stack overflow, reddit, and quora. My google fu is failing me in this en-devour. The environment I am using would be on pythonanywhere, so I don't believe I could use ghostscript or imagemagick on these scripts. I could be wrong, I don't know. What are my options for converting these documents into images? -
What is the @property in Django?
What is the @property in Django? Here is how I understand it: The @property is a decorator for methods in a class that gets the value in the method. But, as I understand it, I can just call the method like normal and it will get it. So I am not sure what exactly it does. Example from the docs: from django.db import models class Person(models.Model): first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) birth_date = models.DateField() def baby_boomer_status(self): "Returns the person's baby-boomer status." import datetime if self.birth_date < datetime.date(1945, 8, 1): return "Pre-boomer" elif self.birth_date < datetime.date(1965, 1, 1): return "Baby boomer" else: return "Post-boomer" @property def full_name(self): "Returns the person's full name." return '%s %s' % (self.first_name, self.last_name) What is the difference of if it is there vs if it isn't? -

How to specify custom authentication and permissions for specific actions in django rest framework

How to inherit from another view in Django
I am trying to make a simple website where user can order someting to eat. So I've got a view with lots of methods - 'pizza_sizes' is only one of them: class PizzaOrderView(TemplateView): template_name = 'pizza/pizza_order.html' pizza_type = ProductType.objects.filter(name='Regular Pizza').values_list('id', flat=True)[0] def post(self, request): to_return = add_to_cart(request) return to_return def pizza_sizes(self): sizes = Product.objects.filter(type=self.pizza_type).values_list('size__name', flat=True).distinct() return sizes I also have a ListView displaying all products that user has in cart. class CartView(ListView): template_name = 'orders/cart.html' From this page user can either delete or update product. So I am using UpdateView to let him update it, but then again I need all those methods (that I use in PizzaOrderView). I could rewrite those methods to this view, but it doesn't make much sens, I tried to inherit it like this: class ProductUpdateView(UpdateView, PizzaOrderView): model = CartItem fields = '__all__' pizza_type = list(ProductType.objects.filter(name__contains='Pizza').values_list('id', flat=True)) def post(self, request, **kwargs): cart_id = self.kwargs.get('pk') to_return = update_user_cart(request, cart_id) return to_return def get_template_names(self): product_type = CartItem.objects.filter(id=self.kwargs.get('pk')).values_list('product__type', flat=True)[0] if product_type in self.pizza_type: self.template_name_suffix = '_pizza_update' else: self.template_name_suffix = '_form' return super().get_template_names() And then use it in my template, but then it throws an AttributeError: 'ProductUpdateView' object has no attribute 'object' As if it somehow lost its 'object' … -

Here is my Code so far: views.py (login) def login_view(request): if not request.user.is_authenticated: if request.method == 'POST': login_form = Login_form(request.POST) if login_form.is_valid(): username = login_form.data.get('username') password = login_form.data.get('password') domain_name = "@my.domain.com" if domain_name not in username: username += domain_name try: user = authenticate(username=username, password=password) print(user) # this gives me None if user is not None: if user.is_active: login(request=request, user=user) return redirect('index') else: form = AuthenticationForm() messages.error(request, 'Try again!') return render(request, 'myapp/login.html', {'form': form}) except ldap.LDAPError as e: print(e) # no error is displayed here form = AuthenticationForm() messages.error(request, 'Try again!') return render(request, 'myapp/login.html', {'form': form}) ### Some more funcs to ### redirect to login.html ### if the login fails settings.py: AUTHENTICATION_BACKENDS = ( 'django_auth_ldap.backend.LDAPBackend', ) AUTH_LDAP_SERVER_URI = "ldap://my.domain.com:389" AUTH_LDAP_BIND_DN = "CN=Users,DC=my,DC=domain,DC=com" AUTH_LDAP_BIND_PASSWORD = "" # I tried with blank password for anonymous bind or # with "%(password)s" as template but I don't know if that's possible # and also without the AUTH_LDAP_BIND_PASSWORD setting AUTH_LDAP_CONNECTION_OPTIONS = {ldap.OPT_REFERRALS: 0} AUTH_LDAP_USER_ATTR_MAP = {'group': "memberof", "first_name": "givenName", "last_name": … -

django: Ajax POST response not loading in template
In my django template, An AJAX call is being made for a POST Request (to create an object instance). Template file (making ajax call): <script> $(document).on('submit', '#xyz-form', function(){ $.ajax({ type: 'POST', url: '{% url "xyz" %}', data: $("#xyz-form").serialize(), context: this, success: function(data, status) { $('#xyz-container').html(data); }, error: function (err) { alert(err.status + " " + err.statusText); } }); return false; }); </script> Views.py file: class XYZCreateView(LoginRequiredMixin, CreateView): model = XYZ def post(self, request, *args, **kwargs): # condition returns false hence I commented it # if request.is_ajax(): xyz_form = XYZForm(request.POST) xyz_list = XYZ.objects.all() if xyz_form.is_valid(): xyz_form.save() xyz_form = XYZForm() return render(request, 'ajax_data.html', {'xyz_form': xyz_form, 'xyz_list': xyz_list}) The template invoking the AJAX call is 'xyz.html' and the response data is being sent to 'ajax_data.html' file, which should get loaded as an html content in the #xyz-container that is present in the former html file. However, while the result is getting sent, it is not getting loaded in the original template. Where am I going wrong with this. -
