Loose Coupling in Django Templates
I am in a situation Really Confusing .. I Have Read alot about loose Coupling And Also i have read that Django is a loose coupled framework But in django tutorial and also in generic class based views like ListView The context which is going to send to template contains queryset or Model instances like : {'object' : Model.objects.get(id=2)} And use like this :{{ object.title }} Well title is a field in a Model and in this way the template system is going to know so much about model layer and with a change in model fields, the template must change to .. Well if django use this way in Its source code then im missing something... Can someone explain how this is not higg coupling ? And what kind of coding in django is loose coupling? -
create user remotely using built in django user model
I'm trying to figure out how to test the process of using the userviewset from the django quickstart guide to create a user account with postman. I'm assuming I have to make a post request to the "create" route, but postman says "this request doesn't have a body" so I have no idea how to send the email, username, and password. I feel like I'm missing something pretty major here, but I have no idea how to find out what it is. -

Django and Powershell
:) I'm having a problem with two things: I'm unable to run PowerShell script from views.py I cannot find a way to send JSON data via POST First problem I've written a dummy python script that's going to call PowerShell script. getaduser.py import subprocess import json def run_powershell_script(ID, Domain): args = ['-SAMACCOUNTNAME', ID, '-DOMAIN', Domain] result = subprocess.check_output([ 'powershell.exe', '.\\getaduser.ps1', *args ]) return json.loads(result) getaduser.ps1 Param( [Parameter(Mandatory)][string]$SAMACCOUNTNAME, [Parameter(Mandatory)][string]$DOMAIN ) $result = [PSCustomObject]@{ samAccountName = $SAMACCOUNTNAME domain = $DOMAIN } return $result | ConvertTo-Json PowerShell script is now only returning what I passed to it, but in the future, it'll take data from Active Directory, also I don't think it's important now. getaduser.py and getaduser.ps1 are working just fine together when I use them off Django. Example of what I'm getting after running the getaduser.py: Path/getaduser.py {'samAccountName': 'exampleID', 'domain': 'exampleDomain'} But when I try to call the script from the views.py I'm getting an error message saying: Command '['powershell.exe', '.\\getaduser.ps1', '-SAMACCOUNTNAME', 'exampleID', '-DOMAIN', 'exampleDomain']' returned non-zero exit status 1. From what I already understood it might mean that the PowerShell script has not been executed properly, but I'm at loss since it's working without Django. And here's how I call it: … -
how to concatinate a date into a string Django
I'm quite new to DRF so sorry in advance. What I want to do is create a function to concatinate the letter "P", the ID value of another model and the year from a submitted date all into one to make a name. Now the value that I want to add this to is the value on the counter model. Any ideas would be appreciated.

How to filter MongoDB collection from Django to find matching string in a list of strings?
Let's assume MongoDB collections has the following document: { _id: ObjectId('asdasd232344'), article: 'some name', type: 'latest', tags: ['books', 'cars', 'code'] },{ _id: ObjectId('asdasd232345'), article: 'some name', type: 'latest', tags: ['books', 'food'] },... Assuming the model is named Story, I am trying to query the articles that have type latest and 'cars', or 'books' and 'cars' tags. Want to do this in a query instead of looping over the result afterward and filtering the ones that have desired tags in them. news = Story.objects(type='latest'). ???? maybe something like find($in: {'books', 'tags'}) I cannot find what I am looking for online since not sure what is this called or how to search it.

NoReverseMatch: Reverse for 'edit' with keyword arguments '{'title': ''}' not found
This is the extention of the same problem i asked about in a previous question. The problem i'm having here now is that after fixing the problem with the trans views function and expecting the program to run without problems, i get the following error NoReverseMatch at /wiki/Python/edit Reverse for 'edit' with keyword arguments '{'title': ''}' not found.

Django - Unique Collection of Foreign Keys Constraint
I have two models like so: class Group(...): pass class Identifier(...): value = models.CharField(...) group = models.ForeignKey('Group', ..., related_named = 'identifiers') How can I: restrict a Group to only have at most 4 Identifiers?

File/Image field not submitting when using Ajax to submit Django form
I'm currently working on a customized admin page on my site where users will be allowed to update their profile page. I have several fields including an image field for profile images...

TinyMCE - Displaying Text Properly - Django
I'm using the TinyMCE text editor and have it successfully integrated into my Django Website. However when I go to display the TinyMCE document with the same styling, font, color, images, etc. it just displays the content as one single line of text.

Different model field requirements for superuser vs normal user? django
Example(not true example): I want the superusers to have to save on register their username and email. and the normal users to save username, email, and a number(unique=True). I wanted to use the user models django has, but I don't see how when the number has to be unique? or rather I originally wanted it to be the primary key, but only for normal users. Do I have to manually make two different user classes along with the permissions, authentication etc.? or is there separate user models for admin/user in django? I tried(as a complete amateur, new to oop and django)... after gave up on using it as primary key, bc AbstractUser is fly. Tried with onetoonefield, but couldn't make a combined form with UserCreationForm, bc "too many fields error". Also weird to have an important part of the user table be in a different table (or is it?). something like (not 100% accurate): #in models.py class AdminUser(AbstractUser): username email class NormalUser(): ontoonefield(AdminUser) number(unique=True) #in forms.py class NormalUserForm(UserCreationForm): class meta: fields class onetoonefieldForm(NormalUserForm): class meta: add_field += (number) tried playing with required_fields, but again... number is unique tried making two abstractUsers... permissions errors thought about just making it non-unique and … -

Will a SSG get me better SEO, than standard server side rendering? (Django)
I am just about to make my website and I will build it with either Gatsby (React SSG) or Django. SEO and the price of the hosting are the two most important deciding factors to me. I would love to build it with Django because overall I am more experienced in it than Gatsby and I might later add things like Stripe payments, client login,... But as SEO is very important to me, I can't decide between Django and Gatsby. Is the difference in SEO significant? Thank you very much. -
Update QuerySet by attribute variable
Take for example my data below where prop is the queryset I am trying to update, and results is a dict of information. This dict has keys that are attributes in this queryset, and also has keys that are not attributes in this queryset. I only want to update this queryset if it's attribute matches... prop = Property.objects.get(pk=14) results = {'price': '525000', 'code': '55285', 'estimate': '1500'} I know this does not work as it calls for an attribute literally named 'apicall' but this is the logic that I am looking to achieve: for apicall in results: if hasattr(prop,apicall): prop.apicall = results[apicall] prop.save() How can I avoid calling literally prop.apicall and instead prop.price if it exists in the queryset? -
