Best way to integrate a Django project into existing program, using same backend logic?
I am very new to Django so I apologize in advance if there are any misconceptions about the framework within this question. I have developed a log analysis program that currently uses the command-line as the user interface using the cmd2 library. I am attaching an image of the project structure with the different Python files. The program is started from log_analyze.py. The commands are parsed in user_interface.py. Other classes like sddc_log.py, get_logs.py, etc. contain logic that is used in the commands for parsing through logs. We currently run this program from VM that our teammates have access to. We are thinking of also creating a web UI for this program so that team members can connect to the VM from the browser to perform log analysis. My question is what would be the best way to organize a Django project that can leverage the existing logic we have in these other Python files and use that information to populate the web UI. Specifically, what would be the proper file structure? Are there any other aspects that I should pay specific attention to? Would this even be a good use case of Django? Thanks for your help in advance. project … -
How do you use Django Login function properly
What I understand so far is that when you're using regular Django you import and use AuthenticationForm and you put the request.POST there and it will retrieve the user you're looking for. But in this case I'm using DRF and some third party authentication system that retrieve the user for me. so in order to test the login function I made this dummy code to test it: @api_view(["GET"]) def login_view(request): if request.method == "GET": #actuall users that exist user = { "id": 1, "email": "test@gmail.com", "name": "melly", "date_joined": "2021-07-09T11:33:44.440889Z" } login(request, user) return Response('test') and it gave me this error Can someone explain to me about this error and why is this happening, thank you! -
Page title with class based function in django
I want to create page titles+subtitles which I wish to control and occasionally modify from the Admin space and pass them to the templates with class based model. Yet, after I enter the inputs in the admin space, the variable I specify in the template provides not value. That is the fields are empty. What do I do wrong? Any advise as to the logic I should use to pass the template? models.py: class Page(models.Model): page_title = models.CharField(max_length=250) page_subtitle = models.TextField() def __str__(self): return self.self template: <h3 class="title mb-0">{{page.page_title}}</h3> <h6 class="title mb-0">{{page.page_title}}</h6> Views: I tried with different views, none of them functioned.

Save card id to model on form submission
I want to save the stripe payment method id to my order when it's created for recurring orders. When using a previously saved card, it works as intended saving a "card_idxxxxx" which references a stripe payment method. Currently if the new card is input, it saves as "add-new-card", which is wrong. I would like it to save the newly input card to the customer, and also to the payment method field.

How to implement the add/edit links on a field in the admin change page that does not have an expressed FK relationship in the model?
I have a Django 3.x web site. There are 3 models, among others, Document, MetaData, MetaDataValue. The MetaDataValue model has a foreign key relationship to the MetaData model. In a simple world, there would be a foreign key relationship from MetaData to Document. Then the DocumentAdmin would display the MetaData field as a dropdown, filled with the appropriate MetaDataValues. There would also be edit/add (pencil/plus) links next to the dropdown to allow the user to edit/add the MetaDataValue for that MetaData object. However, one of the requirements for the project was not to define which, or how many, MetaData objects would be associated with a particular Document type until run time. Those associations are through another set of models. Therefore, the Document admin change page adds the different MetaData fields to the change admin page at run time, by looking into the database for which MetaData fields are associated with this type of Document, and then adding them to the fieldset through the get_fieldsets method. The implication of this design is that one cannot edit/add values to a particular MetaData field on the Document admin change page, because, I assume, Django lost the underlying foreign key relationship between the Document … -
Django many 2 many through rest framework
I am working on a small project but i cant get the serializers to work I have tried these and i am not sure what i am doing wrong. My model is a many to many through #serializers.py class CompanyVisitedSerializer(serializers.HyperlinkedModelSerializer): company_id = serializers.ReadOnlyField(source="company.id") company_address = serializers.ReadOnlyField(source="company.business_address") company_name = serializers.ReadOnlyField(source="company.business_name") company_address = serializers.ReadOnlyField(source="company.business_address") checked_in = serializers.ReadOnlyField(source="user.checked_in") checked_out = serializers.ReadOnlyField(source="user.checked_out") class Meta: model = CompanyUser fields = ( "checked_in", "checked_out", "company_name", "company_address", "company_id", ) class VisitorSerializer(serializers.ModelSerializer): # visited = CompanySerializer(many=True) visited = CompanyVisitedSerializer( many=True, ) ``` but i get this back empty {}: { "address": "192 millie road", "city": "singapore", "phone": "2066980", ... "visited": [ {}, //i want to populate this with { company: name_of_company, checkin, checkout} {} ] } I have read through these: https://bitbucket.org/snippets/adautoserpa/MeLa/django-rest-framework-manytomany-through Django: Serialize a model with a many-to-many relationship with a through argument
