Django customized authentication Session bug
I'm working on a Django project using a customized authentication build by me, I run into a problem where users can bypass my login and get into the home page by simply typing the URL like this: "127.0.0.1/account/Adam" , "127.0.0.1/account/Bob" , "127.0.0.1/account/Alice" , those people are not registered in the database and yet they receive "welcome Adam", "welcome Bob", "Welcome Alice" I have been trying different methods from adding a global variable called Auth = False, and once a user is found in the database and the password is matched Auth will receive True, this kinda solved my problem but not as expected because once that variable becomes Auth = True example: if bob is registred in database and login has been successfully made, with same session Bob can type those urls and manipulating the last url parameter and get Welcome sam, Welcom Alfred.... from django.http import HttpResponse from django.contrib import messages from django.contrib.auth.models import auth from users.models import Composter from django.core.exceptions import ObjectDoesNotExist class MyView(): Vuser = None # Create your views here. def home(request): return render(request, 'users/home.html') #def compost_supplier_register(request): return render(request, 'users/compost_supplier_register.html') def composter_register(request): if request.method == 'POST': #extracting form data from a POST request and assigning it … -

How to use a relative path for Django FileStorage location in migrations?
I am defining a Model containing a FileField and cannot save the Files this FileField should contain in the media folder for unrelated reasons. Therefore I need to define a FileStorage that saves into a different Path. When defining said FileStorage in my model and passing it the DJANGO_ROOT variable from my django settings to build my location path, this gets resolved into a system specific path once I generate migrations for my models. Because the path is now specific to my development directories, I cannot apply the generated migration file on all of the production servers and generating migrations on all of the production servers is obviously not an option. I have also tried editing the path inside the auto generated migration itself, making it dependent on the django settings in there. Sadly, the manage.py migrate command tells me that it wants to generate new migrations for that model. How can I pass a relative path to my FileStorage location, allowing me to generate migrations for my production servers? My model: class ModelWithFile(models.Model): file = models.FileField( storage=FileSystemStorage(location=os.path.join(settings.DJANGO_ROOT, "folder_name"), verbose_name=_("FileObject"), ) Auto generated migration: from django.db import migrations, models from django.conf import settings import django.core.files.storage class Migration(migrations.Migration): dependencies = [ … -
django, path parameter in form don't work
My path looks like so: path('edit/<str:entry_name>/', views.edit, name='edit'). I want to access this path through a form like so: <form action="{% url 'edit' entry_name=entry_title %}" method="get"> {% csrf_token %} <input type="hidden" name="title" value="{{ entry_title }}"> <input type="hidden" name="content" value="{{ entry_content }}"> <input type="submit" value="Edit"> </form> But then I get this error: Reverse for 'edit' with keyword arguments '{'entry_name': ''}' not found. 1 pattern(s) tried: ['edit/(?P<entry_name>[^/]+)/\\Z']. It seems like entry_name is empty, but I use the entry_name parameter elsewhere on the page and it works fine. {% block title %} {{ entry_title }} {% endblock title %} is not empty, since I can see the titel on the tab-title. -
How to convert field values of a model into field names of a new one (model) in DJANGO 4?
I'm building models for a project in DJANGO 4, but I got stuck when it came to CONVERTING FIELD VALUES OF AN EXISTING MODEL INTO THE FIELD NAMES OF A NEW ONE (MODEL). As may be seen from the image I do attach, I have MODEL A with 'fieldName_3'. I'd appreciate a help to convert the values of this field into the field names of the MODEL B.Descriptive Image My advancing thanks! from django.db import models CHOICES = (('option1','option1'),('option2','option2')) class Model_A(models.Model): fieldName_1 = models.CharField(max_length=50) fieldName_2 = models.CharField(max_length=20) fieldName_3 = models.CharField(max_length=3) class Model_B(models.Model): def values_from_fildName3(): values = Model_A.fieldName_3 for value in values: value = models.CharField(max_length=4, choices=CHOICES) yield value With the code above I get the error "TypeError: 'DeferredAttribute' object is not iterable" -
Get form-data for Django tests
I would like to test a Django form, without spelling out myself all the POSTed data that would normally go into it. In a real application, this data would be provided by the browser, based on the form as rendered (as HTML) by Django. How do I get the data without going through the browser? form0 = MyForm(instance=obj) # form which would be shown in normal usage data = the_magic_function(form0) # data which would be posted if user just pressed submit right away # potentially manipulate some parts of this data to make the test interesting form1 = MyForm(instance=obj, data=data) # actual tests are on form1 -

Django inline formset render by order
I Use Django 4.0.6 and Python 3.10. I have a Form with nested inline formset. The inline formset is orderable (can_order=True). The 'ORDER' value of the form will be set to an instance field "index". I use Javascript to order those forms in the template. When I submit the whole form and the form is not valid then the forms are not rendered by the 'ORDER'/'index' attribute. They will be rendered in the order they were created. To solve this I overwrite the __iter__ function of the formset to "Yield the forms in the order they should be rendered." (see django docs - BaseFormSet). My __iter__ function: def __iter__(self): """Yield the forms in the order they should be rendered.""" if self.is_bound: return iter(sorted(self.forms, key=lambda x: x.instance.index, reverse=False)) #return iter(sorted(self.forms, key=lambda x: x.cleaned_data['ORDER'], reverse=False)) else: return iter(self.forms) When I submit the form I get the following errors according to the values that I want to access (cleaned_data or instance). Error when accessing order through cleaned_data: FormXY has not attribute 'cleaned_data' Error when accessing index through instance: '<' not supported between instances of 'NoneType' and 'NoneType' I set a breakpoint in the __iter__ function to see whats the problem, but there is … -

How to insert count() value when using Django to develop Web front end

I run docker-compose up I don't know why but all the previous logs that took alot of time, generate again. which is why it takes 5 minutes for the server to be up and running.

Bootstrap striped table format lost when updating table with fetch
I am using Django and I have a table which is formatted using bootstrap. The class is class="table table-striped". The table initially looks good. It has a delete button which allows users to delete a row. When clicked the data is deleted from the Django model and the table rows are removed and repopulated using fetch. Everything works well but the striped formatting is lost. The bootstrap formatting is still working to some degree and the table is the same size/shape but the background colour of alternating striped rows is lost. I've tried removing and re-adding the class with the javascript but it doesn't work. Any suggestions would be great. HTML {% if pairs %} <table class="table table-striped" id="pairs_table"> <thead> <tr> <th scope="col">Primer</th> <th scope="col">Product(bp)</th> <th scope="col"></th> </tr> </thead> <tbody> {% for pair in pairs %} <tr> {% if pair.forward.pk == primer.pk %} <td> <a href="{% url 'primer' pair.reverse.id %}">{{ pair.reverse }}</a> </td> <td>{{ pair.product }}</td> <td id="delete_pairing"> <button type="button" class="btn btn-warning" onclick="delete_pair('{{primer.id}}','{{pair.reverse.id}}')"><i class="bi bi-trash3"></i></button> </td> {% else %} <td> <a href="{% url 'primer' pair.forward.id %}">{{ pair.forward }}</a> </td> <td>{{ pair.product }}</td> <td id="delete_pairing"> <button type="button" class="btn btn-warning" onclick="delete_pair('{{primer.id}}','{{pair.forward.id}}')"><i class="bi bi-trash3"></i></button> </td> {% endif %} </tr> {% endfor %} JAVASCRIPT … -

django - mariadb 1146 error after change database
used pytest-django==3.5.0 aws rds-mariadb 10.6 To upgrade the version 10.3 to 10.6 of my mariaDB, I upgraded and switched the version of green using blue/green of aws rds. On the surface, both the table and the data seemed fine. But after the change, django throws error 1146. After changing the database, I thought it was a cache problem, so I tried changing the url route address, but it didn't work. I also tried running makemigrations and migrate in manage.py but it didn't work. Now, I think the django Model's meta doesn't seem to apply. Because my actual table name is alarminfo in lowercase but the error log says (1146, "Table 'db.AlarmInfo' doesn't exist") are indicated in uppercase. class AlarmInfo(models.Model): alarmUID = models.BigAutoField(db_column='AlarmUID', primary_key=True) # Field name made lowercase. userUID = models.BigIntegerField(db_column='UserUID') # Field name made lowercase. alarmType = models.IntegerField(db_column='AlarmType') # Field name made lowercase. content = models.TextField(db_column='Content') # Field name made lowercase. registerDate = models.DateTimeField(db_column='RegisterDate') # Field name made lowercase. class Meta: managed = False db_table = 'alarminfo' I'm assuming this might be the problem, but I haven't been able to find a solution. Is this something that has changed in mariadb 10.6 or the action I need to take … -

How to add multiple options to a feature in Django?
My last question for today. I created a filter to only show items with certain values. A list of social measures is displayed. There are two questions about having children and unemployment. We have or don't have children, and we are or aren't unemployed. The main problem is that the filter doesn't work correctly, due to the fact that I only add one option "no" to the entity. For example, we have a social measure "child allowance", and it's paid regardless of income. I created this measure with having children "yes" and unemployment "no". And if the user selects having children "yes" and unemployment "yes", then the page won't show this measure, although the person is entitled to it. Because only "no" was introduced into unemployment. How to enter "no" and "yes" at the same time when creating a measure? And for the site to show this measure regardless of the choice of unemployment. measure_list.html <div class="headtext"> <h3>Choose your life features</h3> </div> <form action="{% url 'filter' %}" method="get" name="filter"> <h3>Do you have children?</h3> <ul> {% for measure in view.get_children %} <li> <input type="checkbox" class="checked" name="children" value="{{ measure.children }}"> <span>{{ measure.children }}</span> </li> {% endfor %} </ul> <h3>Are you unemployed?</h3> <ul> … -
Add values to django database from an external python streamlit app
I have a streamlit app that runs machine learning on an image given by the user. I also implemented authentication using django along with a gallery type app that allows users to view stored images if logged in. I want to add the ability to automatically apend the image uploaded on my streamlit app to the database if the user is logged in. What would be the best way to do this? I tried importing my create view into the streamlit app and defining the variables manually. I also tried to import the model and work with that but I couldn't get either of them to work. I also shifted my streamlit app into the same directory as the django app to prevent PATH errors. -
