React axios request to Django backend is empty
So I am trying to send a set of scans (dcm files) to my Django server from my React App. The request should be as follows [ { "scans": [ {"scan_image": <dcm file data>}, {"scan_image": <dcm file data>} ], "name": "Set Name." }, { "scans": [ {"scan_image": <dcm file data>}, {"scan_image": <dcm file data>} ], "name": "Set Name." } ] As shown the request payload is an array of objects. The objects are composed of two attributes, "scans" and "name" where scans attribute is an array of objects containing the data from dcm files. I read the data via the readAsDataURL method of the FileReader object instantiated as I iterate over the files selected by the user to upload. Here is a log of the data gathered in the object needed to be send to the server. Log of the request containing the files to be uploaded to the server Here is a snippet of the axios request upon finishing the request object generation axios({ url: 'http://127.0.0.1:8000/create_sets/', data: requestObject, method: 'post', headers: { "Content-Type": "application/json" } }) .then(res => console.log("Success") ) .catch(res => console.log(res) ) Upon running that script, unfortunately the request payload looks like this [ { "name":"5-AX T1-28522", … -

What oauth library should I use for one-legged authorization
I am trying to create a Django application for one-legged authorization and using python 3.7. I am confused as to which library should I use for the same.

Logging User statistics in Django
I am using Django's auth_user model and wanted to log the user activities(accessed page details) in my table. I explored and figured out to use django-request module. I have installed django-request 1.5.2 for django 1.8 version. I'm getting this error "NotADirectoryError: [Errno 20] Not a directory: '/pkg/software/python/3.6.0/lib/python3.6/site-packages/django_request-1.5.2-py3.6.egg/request/migrations' and also I couldn't find this directory inside my site-packages.

How to split log file using Selenium with Django

Multiple Django Forms in Single View: Why Does One POST Clear Other Forms?
I'm trying to implement three forms on the same page in Django. Each form has its own submit button as shown in my code. When I submit data on any one form, the data is saved but the other forms go blank upon the resulting refresh, and I get a validation error on the other forms if a field was required, for example. My hunch is that the way Django handles the POST and subsequent page refresh is what's causing the problem, and it's trying to validate all forms regardless of which submit button I press. I thought mapping the button names as shown would prevent this but clearly not, and perhaps I'll have to handle each form individually with AJAX to solve this. However I'm not SURE that's the fix, and would love it if someone could shed light on what's really happening (i.e., explain what Django is trying to do upon submit) so I can better understand how to solve. Any help is extremely appreciated. Handling multiple forms in one view in Django is anything but straightforward. Here's my code: Views.py def update_machine_view(request, brand_name_slug, mclass_slug, profile_slug): machineentry = MachineEntry.objects.prefetch_related().select_related().get(profile_slug=profile_slug) f_plate = PlateForm(request.POST or None, instance=machineentry.plate) f_dimensions = DimensionsForm(request.POST … -

How to write a QuerySet using F expressions on a related model's FK field in Django

Question on customizing Django auth templates
I'm using Django 3 and Python 3.7. I've been fuddling through some of the tempalates, but I can't seem to get "success" templates to be found, for instance "password_change_done" and "password_reset_done". Both give similar Error messages. NoReverseMatch at /users/password_change/ Reverse for 'password_change_done' not found. 'password_change_done' is not a valid view function or pattern name. I have this in my project urls.py: urlpatterns = [ path( "users/", include( "users.urls" ) ) , path( "admin/", admin.site.urls ) , path( "", include( "main.urls" ) ) # Played with this up top, and here on the bottom. ] And in users\urls.py: urlpatterns = [ # Include default auth urls. path( "", include( "django.contrib.auth.urls" ) ) ... ] I even tried adding a TEMPLATES.DIRS value to point to user/templates. TEMPLATES = [ { "BACKEND": "django.template.backends.django.DjangoTemplates", "DIRS": [ os.path.join( BASE_DIR, "users/templates" ) ], # With and Without this. "APP_DIRS": True, ... }, }, ] I feel like path( "", include( "django.contrib.auth.urls" ) ) should contain the correct reference, but do I need to list each one individually? How should I do that? -
Duplicate entry '1' for ForeignKey in Testing Django
I'm implement Intergration Test by Selenium for Django I have Model example like this class Product(models.Model): id = models.AutoField(max_length=11, primary_key=True) contract_id = models.IntegerField(blank=True, null=True) name= models.CharField(max_length=255, blank=True, null=True) productType= models.OneToOneField( ProductType, on_delete=models.CASCADE, db_column='product_type_id' ) productGroup = models.ForeignKey( productGroup, on_delete=models.CASCADE, related_name="ProductGroup", db_column='product_group_id' ) class Meta: db_table = 'PRODUCT' When I insert a new field to my product I got an error like this, problem is, when I insert or create new product at the first time, It still working well. But When the second times, It got error "Duplicate entry '3' for key 'product_type_id'" I think because table PRODUCT_TYPE have to a constraint product_type_id but, the value I insert has duplicate. But can I fix foreignKey constrain errors -

Feasibility of djano and elfinder interface
I'm trying to determine the software I want to use to develop a web based GUI. (For this project) The main goal of the interface is to let the user interact with files and (for example using a custom right click menu) launch Python function on the selected files. The software I was thinking to use are django and elfinder. The server would be completely implemented in django and would present the elfinder interface to select/rename/move the files. Custom menu items in elfinder would launch Python functions on the selected files. Before embarking in this project (Since I barely know how to use Flask) I'd like to have some opinions and directions on the feasibility of this project with these tools and possibly a minimal example on how to start. Thanks -

Django tables - data in rows
I have a simple loop that looks at the domains and populates the sub domains column. The first column has one domain and one subdomain. So it works fine. The second domain (A6) has two subdomains (A.6.1 and A.6.2). However, the A.6.2 gets pushed to the far right. It should be under A.6.1 and A6 rows should be merged so the domain is only repeated once. So the table should be Domain Subdomain A5 A.5.1 A6 A.6.1 A.6.2 A.6.3 etc. The template tags are: <table class="table table-sm"> <tr> <th>Domain ID</th> <th>Sub Domain ID</th> </tr> {% for domain in domains %} <tr> <td>{{ domain.domain_id }}</td> {% for sub_domain in domain.subdomain_set.all %} <td>{{ sub_domain.subDomain_id }}</td> {% endfor %} </tr> {% endfor %} </table> The above code gives me this: -

Item setting in django model / class

Creating Custom Display Fields in Django Admin (that don't exist in models.py)
I have two fields in models.py numberOfUsers = IntegerField() numberOfUserCredits = IntegerField() In Django admin, instead of viewing two columns with list_display = ['numberOfUsers', 'numberOfUserCredits'] I'd like to instead clean this up a bit and concatenate these two fields for simpler viewing: str(numberOfUsers) + '/' + str(numberOfUserCredits) How can I create a custom field like this in Django admin? I could create a new field in models.py that creates this field automatically on model save, but I am wondering if there is an easier way to go about doing this. -

Django Form With JavaScript ReadOnly
In my django form i have java script that sets my academic field to zero if a certain time frame is selected which works fine, however i want to make that field disabled as well so the user cant remove the 0.

Updating a BooleanField via onClick
Good Evening all, apologies for what is likely a very basic question, but I've been lurking here for a few days and haven't yet come across a solution that fits. Long story short, I have a very simple model with a boolean field that I'd like to toggle via a click. The model file is: class Book(models.Model): title = models.CharField(max_length=254, default='') author = models.CharField(max_length=254, default='') genre = models.CharField(max_length=254, default='') price = models.DecimalField(max_digits=6, decimal_places=2) checkedOut = models.BooleanField(default=False) archived = models.BooleanField(default=False) I've tried inserting the following method in the relevant views / models files (both to no avail): def check_in_out(self): if self.checkedOut == False: self.checkedOut = True else: self.checkedOut = False self.save() I have the following in the urls: url(r'^$', check_out, name='check_out') and the html for the relevant button is: <button class="check_btn button button-outline" method="post" type="submit" onClick="{% url 'check_out' %}"> <i class="fas fa-book"></i> </button> I'm sure that I'm missing something obvious - or am trying to oversimplify a more complex task, but nothing seems to work. I also tried following the advice here Change a boolean value after a click on a button in Django but similarly am having no joy. -
Fetch calls to RESTful API fail to authenticate on iOS after React Native 0.61 update
I'm working on a React Native app which needs to make API calls to a RESTful API built on the Django REST framework. To authenticate, our API has a login endpoint which sends back a sessionid cookie in the header, which we then send back in future request headers to receive user-specific information. On Android this works as expected, however on iOS when sending exactly the same request after successfully logging in the server throws an error due to the user being unauthenticated. The only noticeable difference in these tests is that on iOS the server returns an empty sessionid after making the second call (sent with a valid sessionid): "headers": Object { ... "Cookie": "sessionid=\"\"; ..." } We recently updated to Expo SDK 36, which includes an update to React Native 0.61. Prior to this update, both Android and iOS versions worked as expected, however I cannot be sure this was the direct cause as there was a ~2 week break over Christmas directly after updating before discovering the issue. This snippet shows how we get the cookie when making a request (currently avoiding using extra libraries to simplify the process): response = await fetch(requestConfig.url, requestConfig) .then(result => { … -
