Not able to run django with lighttpd

Can I do direct database updates in Django easily?
I am trying to write a web application that displays the content of a database as a website, e.g. in the form of a table, and lets the user update the table entries, which should automatically be reflected in the database, so that on page reload, the table looks exactly as the user left it. Since my web development skills are fairly outdated, I wanted to take this as an excuse to try some new stuff. I know my way around SQL and Python quite well, so I thought Django would be a good choice. I don't have a lot of experience in Javascript however. I already worked through the tutorial, which covers classic HTML forms where you enter a bunch of data and then hit "submit" to push to the database. What I would really prefer though is to have my whole table freely editable and either immediately save any change to the database (e.g. whenever I click a checkbox or "focus out" of a text box). As a second option I thought about having a single "save" button for the whole page (which may easily be several screens in size). Now, for the first option, I assume I … -
Django Models - Reverse Foreign Key
These two classes have Foreign Key to each other and class OrderRow is representing a row which belongs to an Order, I want to know is there any way to set "rows" attribute inside class Order to show a list or query-set of all related order rows by calling it on an object or instance of class Order? class OrderRow(models.Model): product = models.ForeignKey(Product, on_delete=models.CASCADE) order = models.ForeignKey('Order', on_delete=models.CASCADE) amount = models.IntegerField(default=0) class Order(models.Model): customer = models.ForeignKey(Customer, on_delete=models.CASCADE) order_time = models.DateTimeField(auto_now_add=True) total_price = models.IntegerField(null=True, blank=True) **rows = models.ForeignKey('OrderRow', on_delete=models.CASCADE, related_name='order_rows')** -
How to call a function in template which is defined in a Django model?
I am extremely newbie to Django, Sorry in the advance for asking the wrong question. I want to create a function to sum the values of a column and call it on my template in Django. Model: class Invoice(models.Model): product_name = models.CharField(max_length=255) purchase_date = models.DateTimeField(auto_now=True) cost_price = models.IntegerField() selling_price = models.IntegerField() @property def get_total(self): amount = Invoice.objects.aggregate(Sum('selling_price')) return amount I created this get_total function to sum of the values of selling_price column.

Here's the output. Output Image I know it's quite silly, but I am unable to figure it out. Help, Please. -

How to change font-size of datetimepicker xdsoft calendar

Django Admin CharField Choices List Dependent On Other Field
I have two models class Animal(models.Model): TYPE = ( ('cat', 'Cat'), ('dog', 'Dog'), ('chicken', 'Chicken'), ) type = models.CharField(max_length=10, choices=TYPE, default='cat') class Injury(models.Model): BODY_PART = ( ('leg', 'Leg'), ('eye', 'Eye'), ('beak', 'Beak'), ) animal = models.ForeignKey(Animal, on_delete=models.CASCADE) injured_body_part = models.CharField(max_length=10, choices=BODY_PART, default='Leg') how_it_happened = models.CharField(max_length=100) So in my contrived example an animal can have many injuries and an injury can belong to one animal. When I create a new Injury in Django Admin I want it to restrict the choices for injured_body_part depending on which Animal I have selected. For example, if I select dog the injured_body_part option for beak wouldn't appear. I have found similar questions on SO but they are either very old or have unsuitable answers. Thank you. -

mocking HTTP requests Django model.save error
I am trying to mock for testing purposes some HTTP calls on Django. The function that is making the requests (lets say it is called reqs() ) is this: try: response = requests.request('POST', url, data=json.dumps(payload), headers=headers, params=querystring) if response.status_code == "200": alpha.pending_sync = False alpha.save() except requests.exceptions.RequestException as e: app_logger.exception("Failed sync, error: %s" % e) Now on the test part i wrote this one: with patch('requests.request') as mock_request: mock_request.return_value.status_code = "200" reqs(alpha) mock_request.assert_called() Everything works fine but there is a problem with alpha.save() and mock.response. I get an error django.core.exceptions.FieldError: Aggregate functions are not allowed in this query. Probably i need to mock a response so the alpha.save() takes that response and not some MagicMock stuff. Also i found this one ref but i did not manage to get anything working. Any ideas ? -
What is the best way to build a document index in Django?

And I want to ocr them and build an index, which I can search through when I am looking for a document. Right now I would just a column with text fields in my db and I would just go through every object, when I look for a certain search phrase. But perhaps there are better approaches and you have some advice for me how to improve the index search :) -
Invalid submitted Django form data being temporarily used elsewhere in a template
I am trying to make a view for users to change their usernames and emails. The page works as expected for the most part. However, there is an issue that occurs when a user inputs another user's username. You see, the profile editing page has a heading that displays the current user's username and email. When the user inputs a duplicate username, the heading becomes the invalid username until the page is refreshed. Here is the relevant code: View @login_required() def profile(request): if request.method == 'POST': u_form = UserUpdateForm(request.POST, instance=request.user) p_form = ProfileUpdateForm(request.user, request.POST, instance=request.user.profile) if u_form.is_valid() and p_form.is_valid(): u_form.save() p_form.save() messages.success(request, 'Your account has been updated.') return redirect('profile') else: u_form = UserUpdateForm(instance=request.user) p_form = ProfileUpdateForm(request.user, instance=request.user.profile) return render(request, 'users/profile.html', context(title='Procfile', u_form=u_form, p_form=p_form)) Form class UserUpdateForm(forms.ModelForm): email = forms.EmailField() class Meta: model = User fields = ['username', 'email'] Template {% extends "courses/base.html" %} {% load crispy_forms_filters %} {% load crispy_forms_tags %} {% block content %} <div class="content-section"> <div class="media"> <div class="media-body"> <h2 class="account-heading">{{ user.username }}</h2> <p class="text-secondary">{{ user.email }}</p> </div> </div> <form method="POST" enctype="multipart/form-data"> {% csrf_token %} <fieldset class="form-group"> <legend class="border-bottom mb-4">Profile Info</legend> {{ u_form|crispy }} {{ p_form|crispy }} </fieldset> <div class="form-group"> <button class="btn btn-outline-info" type="submit">Update</button> </div> </form> </div> {% … -
