How to pass file directly from the python file to detect macro using oletools?
I did the research for detecting the macros and I found oletools.

CSS just won't update on CKeditor even when clearing cache
I've added CKeditor to my django website. It works, except the styling is a bit wrong. I figured I'd just grab the labels and make them white so I can see them - messing around with f12 I found that if I comment the color out here, the labels indeed turn white. Cool, no big deal, just go to editor.css and edit color: #000 to color: #fff like this: .cke_reset_all, .cke_reset_all *, .cke_reset_all a, .cke_reset_all textarea { margin: 0; padding: 0; border: 0; background: transparent; text-decoration: none; width: auto; height: auto; vertical-align: baseline; box-sizing: content-box; position: static; transition: none; border-collapse: collapse; font: normal normal normal 12px Arial, Helvetica, Tahoma, Verdana, Sans-Serif; color: #fff; text-align: left; white-space: nowrap; cursor: auto; float: none } I save, python manage.py runserver, ctrl+f5 only to find that nothing changed. I also tried collectstatic but I don't think that's relevant (0 files were modified). Inspecting the element again brings up the old css file with color: #000. Going to the network tab also reveals the same old file. What's going on here? -
Encode an encodable struct to Alamofire POST parameters - Swift
I'm trying to connect my front-end iOS app (Swift) to my Django backend. I have this struct: struct APIAccountID: Codable { let username: String let password: String enum CodingKeys: String, CodingKey { case username = "username" case password = "password" } } Which is codable. I'm trying to pass the data of this struct in an Alamofire POST request. So I'm trying to get encode the object like this: if let data = try? JSONEncoder().encode(accountID) { return data } else { print("Error: encoding post data") return nil } And I get this error when I send the request: { "non_field_errors" = ( "Invalid data. Expected a dictionary, but got str." ); } -
Django - Multi-steps forms/split-form, how to?
quite new here. I want to create a multi-steps form. The idea is that I have a Log form that I would like to split in 4 pages(with many many skippable fields). Atm i created 1 app, with 1 model and 4 tables, 1 for each "split" and respective urls and view. My objective is to have a starting listview from where i can A)create a new log(CreateView) at page1 then, keeping the pk of the session move to page 2,3,4 and save (or save at the end of each page). At the same time i need to be able to modify it(updateView)in the same format(4 pages). How do I keep th pk to pass on? I tried to use 1 listview, with combined createview and updateviews. I also tried with formsets but I haven't been able to make much progress. What is the best way and practice to realise this multi-step form? I've read of a possible Django-tools (Wizard). Is that a viable solution or is there a better and simpler way? Thanks in advance for the help!** -

Duplicate records being created in Django Command
I'm having trouble with this function that is creating duplicate records. I have a couple pages with documents that contain a response with document as a list of records. Each page contains a different number of document in this this list. When all the records are created in the database, it starts to duplicate them because the amount of pages exceeds the number of pages that have documents in them. Here is what the response for each page looks like: { "page": 3, "limit": 10, "count": 2, "machines": [ { "document_id": "1234", "location": "123 Random address", "location_name": "Scraton", "location_coordinates": { "latitude": 54.443454, "longitude": -124.9137471 }, { "document_id": "1235", "location": "124 Random address", "location_name": "New York", "location_coordinates": { "latitude": 233.385037, "longitude": -40.1823481 }, ] } Here is the function that is creating duplicates. def sync_all_documents(limit=1000, page_start=0,page_end=10): for page in range(page_start, page_end): try: response_data = get_documents(limit=limit, page=page) logger.info(f"Page Count: {response_data['count']}") if(response_data['count'] == 0): return except RequestError as ex: return # loop short circuits here try: documents = response_data[“documents”] for document in documents: # STEP 1 - Location try: serialized_location = serialize_location_information(document) location, l_created = Location.objects.get_or_create( latitude=serialized_location["latitude"], longitude=serialized_location["longitude"], defaults={ "country": serialized_location["country"], "state": serialized_location["state"], "city": serialized_location["city"], "street_address": serialized_location["street_address"], "postal_code": serialized_location["postal_code"], "name": serialized_location["name"], "status": serialized_location["status"], … -

Why does the intial value of a form field not display in one field?
I am trying to display this form with initial values. However, only the initial value for the field 'title' shows up and not the 'content' field. Moreover, if I change the initial value of the 'title' field to entryPage the required value will display in that field but this does not work in my 'content' field. form class NewPageForm(forms.Form): title = forms.CharField(label="Title:", max_length=100, widget=forms.TextInput(attrs={'class': 'formpgtitle', 'placeholder': 'Type in the title of your page'})) content = forms.CharField(label="Content:", widget=forms.Textarea(attrs={'class': 'formpgcont', 'placeholder': 'Type content in markdown form starting with page heading - ## heading.'})) edit = forms.BooleanField(initial=False, widget=forms.HiddenInput(), required=False) views.py def edit(request, entry): entryPage = util.get_entry(entry) if entryPage is None: return render(request, "encyclopedia/error.html", { "entryTitle": entry }) else: form = NewPageForm() form.fields["title"].initial = entry form.fields["title"].widget.attrs['readonly'] = True form.fields["content"].intial = entryPage form.fields["edit"].intial = True return render(request, "encyclopedia/newpage.html", { "form": form, "edit": True, "entryName": entry }) -

Django - Dynamically populate the choices of a CharField with the fields of some other models: Models aren't loaded yet RegistryError
Good day everyone, hope you're doing really well. Straight to the point, let's say we have anpp w models: from django.apps import apps from django.db import models class A(models.Model): # A lot of fields go here class B(models.Model): # A lot of fields go here # And some more models ... class ModelChoices(models.TextChoices): A = 'A' B = 'B' ... class Filterset(models.Model): model = models.CharField(max_length=32, choices=ModelChoices.choices) attribute = models.CharField(max_length=32, choices=auto_generate_attributes().choices) def auto_generate_attributes(): all_attributes = set() for model_name in ModelChoices.values: ModelClass = apps.get_model(model_name) model_fields = ModelClass._meta.get_fields() model_attributes = [(attr.name, attr.name) for attr in model_fields] all_attributes.update(model_attributes), Attributes = models.TextChoices( 'Attributes', list(all_attributes), ) return Attributes Now you're probably wondering what's the point of this table. In short, I'll use it in a M2M relationship with another model so that an User can filter on values of different models at once and return a list of FK objects that all models share (Sounds abstract, but trust me). But the other models are still a work in progress and will edit/create new fields as time goes, that's why I have to generate them dynamically instead of hard-coding them. The issue is trying to get the models classes at initilization time to popuplate the choices of … -

ValueError while logging out user from the page dynamically created by passing pk
