How do I redirect to url2 after performing a task on url1 in django?
I have a edit-scholarship.html in which you can search for a scholarship by passing name and type and then select that scholarship and edit it in update-scholarship.html by passing scholarship id from the url. Now after updating the scholarship, the url becomes http://127.0.0.1:8000/admin/updatescholarship/50 50 is the scholarship id passed into the url Now when I try to go to dashboard in my project, the url becomes http://127.0.0.1:8000/admin/updatescholarship/dashboard I dont't want the dashboard to get appended after the updatescholarship . The url should be http://127.0.0.1:8000/admin/dashboard Here's my edit-scholarship view def admin_editscholarship(request): if request.method == 'POST': name = request.POST['sch_name'] type = request.POST['sch_type'] schdets = ScholarshipDetails.objects.filter(name = name,type = type) if schdets is not None: #if something exists in scholarship details, then print it print('Scholarship found') else: schdets = None return render(request,'admin-editscholarship.html',{'schdets':schdets}) Here's my update-scholarship view def admin_updatescholarship(request,pk=None): #can update the new data in the selectd scholarship if pk: sch = ScholarshipDetails.objects.get(pk = pk) if request.method == 'POST': form = EditScholarshipForm(request.POST,instance=sch) if form.is_valid(): form.save() print('\nform saved') args = {'form' : form} messages.success(request,'Successfully updated') return render(request,'admin-editscholarship.html',args) Here's my urls.py path('admin/dashboard',views.admin_dash), path('admin/addscholarship',views.admin_addscholarship), path('admin/editscholarship',views.admin_editscholarship), url(r'^admin/updatescholarship/(?P<pk>\d+)$',views.admin_updatescholarship,name = 'updatescholarship'), path('admin/students',views.admin_students), path('admin/requests',views.admin_requests) -
How can I stream big data to Google Cloud Storage?
I am working on a system for analyzing data of any size and format streamed by the users to my private cloud based on Google Cloud Storage. Do you have any ideas how can I allow them to stream big data? At the moment I use Django API and I do this in this way: def upload_blob(source_file_name, destination_blob_name): blob = bucket.blob(destination_blob_name) blob.upload_from_filename(source_file_name) print('File {} uploaded to {}.'.format( source_file_name, destination_blob_name)) It works correctly with small files however when I send for example large movie I get the error shown below. I am aware that this is not the optimal solution but I have no idea how can I solve this. As you can notice at the moment they send me requests with the blob format but with very large files it does not work. Do you have any ideas how can I solve my problem and send users data of any size to Google Cloud Storage?

Django: OnetoOne relations using fixtures and uuids
I have a model called user, and another one called patient as follow: class Patient(Model): user = OneToOneField('users.User', on_delete=CASCADE, related_name="patient", blank=True, null=True) class User(Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) All the migrations work correctly and now I'm trying to add some data to the DB using fixtures. Users fixtures work well, but it seems that Patient fixtures do not detect the UUID's from users: django.db.utils.IntegrityError: Problem installing fixtures: insert or update on table "patients_patient" violates foreign key constraint "patients_patient_user_id_b53513b7_fk_users_user_id" DETAIL: Key (user_id)=(97179680-7042-11ea-bc55-0242ac130003) is not present in table "users_user".

How do i add username of logged in user to model field in django
How do i add username of currently logged in user to field in my model? For example, i need to store info about user like name, email and so on in model, other than default Django user model, but i still use default one to store credentials. I want to establish relationship between those, so i created username field in my model. How do i fill it with current user's username upon saving the corresponding form? My model class ApplicantProfile(models.Model): name = models.CharField(max_length = 50) dob = models.DateField() email = models.EmailField() description = models.TextField() username = <something> What do i change <something> with? My form class ApplicantProfileEdit(forms.ModelForm): class Meta: model = ApplicantProfile fields = [ 'name', 'dob', 'email', 'description', ] My view def ApplEditView(request): form = ApplicantProfileEdit(request.POST or None) if form.is_valid(): form.save() form = ApplicantProfileEdit() context = { 'form':form } return render(request, "applProfileEdit.html", context) P.S. I tried to import models straight to my views.py, and assign request.user.username to username field of the model in my view, but it didn't work, just left that field empty. I had username as CharField when i tried this. -
How to stream a file in a request?
We have a react application communicating with a django backend. Whenever the react application wants to upload a file to the backend, we send a form request with one field being the handle of the file being upload. The field is received on the Django side as an InMemoryUploadedFile, which is an object with some chunks, which can be processed for example like this: def save_uploaded_file(uploaded_file, handle): """ Saves the uploaded file using the given file handle. We walk the chunks to avoid reading the whole file in memory """ for chunk in uploaded_file.chunks(): handle.write(chunk) handle.flush() logger.debug(f'Saved file {uploaded_file.name} with length {uploaded_file.size}') Now, I am creating some testing framework using requests to drive our API. I am trying to emulate this mechanism, but strangely enough, requests insists on reading from the open handle before sending the request. I am doing: requests.post(url, data, headers=headers, **kwargs) with: data = {'content': open('myfile', 'rb'), ...} Note that I am not reading from the file, I am just opening it. But requests insists on reading from it, and sends the data embedded, which has several problems: it can be huge by being binary data, it corrupts the request it is not what my application expects … -
Create custom models from html in Django
I want from a html page create a custom model from existing models. For example I have a generic model called Object : Model Object: Name Description Date When a user create a new Object, I want him to be able to choose fields from a list to add them in the new Object. In the list I have for example : List: - Temperature - Humidity And he can add as many fields as he wants (maybe add user custom fields ?). If he creates a new Object with Temperature but not with Humidity the object should be : Model Object: Name Description Date Temperature Is there a way to do this with Django ? Thank you for your help. -

"module 'django' has no attribute 'VERSION'" error when setting up PostgreSQL for Saleor
I am using Saleor, a Django ecommerce backend template, and am trying to get it set up as given here. I downloaded all the packages at the top, but am struggling to get Postgres working. Originally, I downloaded Postgres from EnterpriseDB, and when trying to "createuser" I would get a "postgres psql: fatal: could not find own program executable" error. Then, I uninstalled postgres because it seemed like the trouble may be coming from a weird file path, and downloaded it again, this time using homebrew. I then seemed to have overlapping files, and Postgres was now, for some reason, downloaded to my Applications folder instead of /Library. At this point, when I tried to "createuser", I got "permission denied" and briefly spent some time trying to do it with root access, to no avail. So, I clean uninstalled both versions of Postgres on my computer, and downloaded it via homebrew again. Then I went into the PSQL shell and physically typed out SQL commands to create both the 'saleor' user and DB, which is now done. I am now downloading PgAdmin and will connect it to the Postgres downloaded via Homebrew to manage these users/DBs. Then, when trying to … -
TypeError: expected string or bytes-like object - Django

How to update change history for a User object from backend view function instead of Django admin panel?
I understood that the change history for a specific object gets updated when we do something on django admin panel. Like for a user, if we add or remove the groups from admin panel, it will be part of change history for that particular user object. I have a case where I need to upload a CSV file containing a list of users and their Titles. Based on these titles, I need to add specific groups to the user. I was able to achieve that adding and removing of groups for the user. The issue here is that I don't see the change history for the user object getting updated when I assign groups to the user from backend instead of admin panel. Is there any thing that would be helpful for me to achieve this? I have gone through this Tying in to Django Admin's Model History . But it's adding a record in Log Entries and not in the change history of the object. Is there any place I can look at for the change history of objects like any table in database where in I can create a new record after every modification of the user etc? -

Wagtail Stream Image Ignoring HTML File
I've set up a stream file and all the blocks work except image. I know I must have overlooked something obvious. The image is displayed. It just ignores the html.

In my blocks.py, I have: class ImageFloatLeftBlock(ImageChooserBlock): """Float an image to the left""" class Meta: template = "streams/image_float_left_block.html" icon = "doc-full" label = "Float Image Left" The html file is ignored. I put and h1 in it just to be sure. The image is being displayed. I assume it isn't looking at the streams/image_float_left_block.html file. It does work for the other fields that are set up the same way. For example, this one works: class TitleTextBlock(blocks.StructBlock): """Title and text and nothing else.""" title = blocks.CharBlock(required=True, help_text="The heading for the block") text = blocks.TextBlock(required=True, help_text="The body of the block") class Meta: template = "streams/title_text_block.html" icon = "edit" label = "Title & Text" I suspect it's the parent class in the invocation: class ImageFloatLeftBlock(ImageChooserBlock): I can't … -
