group items with same value with that value as header
I'm practicing my python and django by making a recipe site. I can add ingredients (class RecipeIngredient) per recipe using inlines, searching for ingredients i already have in my database (class Ingredient) (with nutrional facts etc). This results in one big list of ingredients per recipe. To order them I added a step and a stepnum attribute. I return a list ordered by the stepnum, but how can I div them apart? For instance. If you make a cake you would have ingredients for the cake, and for the icing. all the ingredients for the icing would get a step value of "icing", and a stepnum of 0. all the ingredients for the cake would get a step value of "cake" and a stepnum of 1. I would like all the ingredients with stepnum 1 to appear under one that has the value associated with the items that have a stepnum value of 1, in this case "cake". How? I have this code on my recipedetail.html: <div><h1> INGREDIENTS: </h1></div> <div> {% for ingredients in recipe.get_text %} <ul> {% for item in ingredients %} <li><em> {{item.1|safe}} {% if item.2 is not None %} {{item.2|safe}} {% endif %} {{ item.0|safe}} </em></li> {% … -
Django migrations wrongly applaying
Basic problem I'm working on a django project where I'm using multiple databases with a custom router. Therefore, django should know which database to use for which app. Now I came across some in my opinion weird behaviour and wanted to ask if anyone knew if that is the correct behaviour or not, especially because the github page doesn't seem to have an issues tracker. To make the point clear, I'm using an extreme example, which I nonetheless tried. For testing purposes, I set the allow_migrate function to just return False. I did create a custom router which overrides the allow_migrate function and I also registered it under the DATABASE_ROUTERS settings. The allow_migrate function is also called, as I checked it with some print statements. How I understand the router usage The way I understand the documentation for using multiple databases with a custom router, the allow_migration method specifies if a migration is to be applied for the current db, app_label and model_name. If it returns True, the migration is applied, if False, it is 'silently skipped' and therefore not applied. What I expected As I set the allow_migrate function to return False all the time, I expected that none … -
Django: Need to check POST request mime type before uploading it to S3
So, here's my basic problem. I have form in my frontend that posts a file to my Django backend. Django will then pass that file off to AWS S3 for storage. I need to verify the file is a PDF or DOC before uploading to S3. I thought to check it's mime type with python-magic like so, form = UploadFileForm(request.POST, request.FILES) if form.is_valid(): mime_type = magic.from_buffer(request.FILES['file'].read(), mime=True) if mime_type in ALLOWED_MIMETYPES: upload(request.FILES['file'], file_name) where upload just basically wraps boto3's upload_fileobj method. However, according to this Stack, the .read() I use in magic.from_buffer() empties the file buffer, so that when I pass the file into the upload method, it no longer exists. I've tried using copy and deepcopy to duplicate the file before checking it's mime type and then passing the duplicate into the upload function, but copy and deepcopy don't seem to work with fileobjects, as the duplicate is also empty after calling .read() on the original. How can I copy the file passed through the POST request so that I can check its mime type before passing it to S3 for storage? Is there another way to check it's mime type that doesn't involve emptying the file buffer? -
How to approve all installed apps permission programmatically in Django

Now I want to allow users to approve permission just like django-admin dashboard. Like select few permissions and then press submit button to add these permissions to selected group. There must be some way doing so, because django admin itself doing it this way. I'd like to get some ideas how can I get this done. -

Django - Serialize an object with an object whitin
guys, I can't figure out how to do the following: I need to serialize a post object. If I do: return JsonResponse([post.serialize() for post in posts], safe=False, status=200) I get but I need to include additional data from the user: I can do it by doing a list like: post_list = [] for post in posts: post = { 'author': { 'user': post.author.user.username, 'name': post.author.user.first_name, 'avatar': post.author.avatar.url, }, 'message': post.message, "created": post.created, 'likes': post.likes.count(), } post_list.append(post) But I think this is not the best way to do it. Is it posibble to nest the user object in the post object using serialize()? Thanks in advance!!!! -
Poor Django architecture leading to "django.db.utils.OperationalError: no such table: main.invTypes"?
I hope I can get some help with an issue I've been beating my head against for a while now. I like to think I'm an intermediate Python developer, I'm working a on a pet project to improve my Django whilst focussing on getting the structure right and understanding how to write more pythonic code. I'm focussing on getting the model definitions correct to begin with and haven't started to look at forms or views yet. Perhaps I'll end up using it as a glorified database interface.... The following code creates a Market Order item which is stored in a database containing all the users data, which is downloaded from a 3rd party API. type_id is referenced in a separate database as it's taken from the static data download available from a 3rd party. I think it makes sense to separate them like this as it'll make database admin easier and cleaner in the future. I've checked and debugged the database router and fairly confident it's setup correctly. class MarketOrder(models.Model): date = models.DateTimeField(auto_now = True) duration = models.PositiveSmallIntegerField(default = 90) is_buy_order = models.BooleanField(default = False) issued = models.DateTimeField(blank=True, null=True) # tzinfo = tzlocal(), location_id = models.PositiveIntegerField(blank=True, null=True) min_volume = models.PositiveIntegerField(default … -

Choosing the right datetimepicker
I am having a tough time finding a datetimepicker that does exactly what I need and works with Bootstrap 4, Django, and Django Crispy Forms. The critical thing I need is the ability for the user to type what they want in the date input field without the calendar popping up with an icon next to the input field upon which they can click if they would like to choose a date visually. I have had problems with a few datetimepickers with no responses on this platform as to how I might resolve those issues. I first tried the Django wrapper for Tempus Dominus (django tempus dominus) which seemed the most logical choice, but it does not play well if you are using Django Crispy Forms layouts to render the forms. When the input is converted to a datetimepicker widget with a clickable calendar icon, the layout is thrown off as the input field's container gains extra height without any detectable CSS margins, padding, etc. It also forces the field to be required when it should not. Also, if the server side validation returns an error, the error text is disabled (changes css of the text element to display:none) although … -

How to share Python method between two Django classes?
I have two classes in my Django models.py file: class ProfileManager(models.Manager): def create_profile(self, user, member): # Set default age to 100 years old when profile is created. years_ago100 = datetime.datetime.now() - datetime.timedelta(days=101 * 365) age = calculate_age(years_ago100) # <- Used here profile = self.create(user=user, person_dob=years_ago100, person_age=age) return class Profile(models.Model): person_dob = models.DateField() person_age = models.IntegerField() objects = ProfileManager() def save(self, *args, **kwargs): # Update to real age when user edits profile for the first time. self.person_age = calculate_age(self.person_dob) # <- Used here too super(Profile, self).save(*args, **kwargs) Each class uses this calculate_age method: def calculate_age(born): today = datetime.date.today() return (today.year - born.year - ((today.month, today.day) < (born.month, born.day))) How can I make this method accessible to both classes? One easy way would be to make the method global like this but that seems like a kludgy way to do it: def calculate_age(born): ... class ProfileManager(models.Manager): ... class Profile(models.Model): ... Also, this wouldn't work if I wanted to access that method outside of this particular models module. Is there a standard way to do this when using Django?
