Impossible to scrape this website anymore
I am currently realising a project for school (torrents stream website like netflix) with Python/Django/NodeJS. Since the begin of project, i am scrapping the IMDb website to get data about movies (synopsis, casting, rate etc.). It worked well. Then, since few days I just can't scrape anymore. My request returns me an Error 503. At first, I thought about IP ban, but when i'm trying to scrap with Curl, it works fine. Actually I'm asking myself if the problem doesn't come from IMDb's robots.txt file ? How to be sure ? If it's the case, there are a way to bypass this ? Do you know any alternative ? Thanks for your help. Bye :) -

Django createsuperuser function: no error but not working

Unable to mailmerge into a template word document when launched on heroku
I am working on a django application in which users input is inserted into a template word document. I used the mailmerge library to achieve this. It was all working fine on my local server but when I deployed the app to heroku it started giving me errors. The error I get on the heroku logs is: File "/app/input/merge.py", line 69, in merge 2019-12-02T07:55:48.252446+00:00 app[web.1]: document.write('documents/'+name+'.docx') 2019-12-02T07:55:48.252449+00:00 app[web.1]: File "/app/.heroku/python/lib/python3.6/site-packages/mailmerge.py", line 120, in write 2019-12-02T07:55:48.252451+00:00 app[web.1]: with ZipFile(file, 'w', ZIP_DEFLATED) as output: I don't understand why it is giving me this error.

Confusion about the django permission and group model?
For example I create permission like this: Permission.objects.create(name='Can add',codename='can_add',content_type=1) Now if I want to apply this permission in some view I need to use permission_required decorator like this @permission_required('app.can_add', raise_exception=True) def some_view(request): ... Here I need to exactly match the permission code_name in the decorator in order to apply the permission . But what if admin(not developer) created new permission with different codename than the codename which is used in a view? We should go manually to the code and edit the codename ? Or is there any better solutions?How can admin apply the newly created permission in the view without manually going in the code? I am thinking it from the normal user perspective, after we gave the project to the client.How can he/she manage such things? -

django-auth-ldap failed to map the username to a DN after switching to LDAPS
I'm building a django project for my company, I had settings like below when I just use simple bind without SSL: AUTH_LDAP_SERVER_URI = 'ldap://some.example.server:389' AUTH_LDAP_BASE_DN = 'some-base-dn' AUTH_LDAP_BIND_DN = 'some-bind-dn' AUTH_LDAP_BIND_PASSWORD = 'some-password' AUTH_LDAP_USER_SEARCH = LDAPSearch( AUTH_LDAP_BASE_DN, ldap.SCOPE_SUBTREE, '(sAMAccountName=%(user)s)') and it worked perfectly. However, due to the security enhancement of our company's LDAP server, we're asked to use LDAP over SSL. So I get a certificate and change my code like this: AUTH_LDAP_GLOBAL_OPTIONS = { ldap.OPT_X_TLS_REQUIRE_CERT: True, ldap.OPT_X_TLS_DEMAND: True, ldap.OPT_REFERRALS: 0, ldap.OPT_X_TLS_CACERTFILE: '/etc/ssl/certs/mycertfile.pem' } AUTH_LDAP_SERVER_URI = 'ldaps://some.example.server:636' AUTH_LDAP_BASE_DN = 'some-base-dn' AUTH_LDAP_BIND_DN = 'some-bind-dn' AUTH_LDAP_BIND_PASSWORD = 'some-password' AUTH_LDAP_USER_SEARCH = LDAPSearch( AUTH_LDAP_BASE_DN, ldap.SCOPE_SUBTREE, '(sAMAccountName=%(user)s)') It no longer works. It keeps saying search_s(xxx) returned 0 objects: Authentication failed for : failed to map the username to a DN. But if I change the filter string for the LDAPSearch() from '(sAMAccountName=%(user)s)' to '(sAMAccountName=<hard-coded-id>)' it works. I've been trying to dig out why this happens and so far no luck. Does anyone have any idea why this is happening? Much Appreciated. -
How to raise error message if data does not exist in django table
I have my table and filter all set up and working but I wish to have an error functionality added to it in such a way that when I query a data which exist in the db, it should show me the result normally, however, when I input a qs which does not exist, it should show me a message on the table that says "record does not exist" instead of a blank table. Here is my view: from django.contrib.auth.decorators import login_required from django.contrib.auth.models import User from django.shortcuts import render from django_tables2 import RequestConfig from django_tables2.export import TableExport from .models import Employee from .models import EmployeeFilter from .tables import EmployeeTable @login_required() def employees(request): filter = EmployeeFilter(request.GET, queryset=Employee.objects.all()) table = EmployeeTable(filter.qs) RequestConfig(request).configure(table) count = Employee.objects.all().count() male_count = Employee.objects.filter(gender__contains='Male').count() female_count = Employee.objects.filter(gender__contains='Female').count() user_count = User.objects.all().count() export_format = request.GET.get("_export", None) if TableExport.is_valid_format(export_format): exporter = TableExport(export_format, table) return exporter.response("table.{}".format("csv", "xlsx")) return render(request, "employees/employees.html", { "table": table, "filter": filter, "count": count, "male_count": male_count, "female_count": female_count, "user_count": user_count, }) -
Specific URL calling

Can we send the HttpResponse of django `render()` in a python dictionary?
What my use case is I need whole render() data into a dictionary which will be having other key values too and finally I can return it as a normal Response. Let suppose my code is: from django.shortcuts import render def my_view(request): # View code here... return render(request, 'myapp/index.html', { 'foo': 'bar', }, content_type='application/xhtml+xml') Now what we are doing here is: render is basically returning a HttpResponse which we are returning. What I need is: Save the return response in a variable x = render(request, 'myapp/index.html', { 'foo': 'bar', }, content_type='application/xhtml+xml') Then can we save it in a dictionary to return as a Response? Like this y = {} y = {name: 'testing', render_response: x} return y -
owner is required in Django template
I have two identical views in which I am editing an existing model record Views.py def edit_product(request, pk): instance = get_object_or_404(Product, pk=pk) form = Producteditform(request.POST or None, instance=instance) if form.is_valid(): form.save() return redirect('employee:products_table') return render(request, 'packsapp/employee/employeeProductEditForm.html', {'form': form}) def edit_warehouse(request, pk): instance = get_object_or_404(Warehouse, pk=pk) form = Warehouseeditform(request.POST or None, instance=instance) if form.is_valid(): form.save() return redirect('employee:warehouse_table') return render(request, 'packsapp/employee/warehouseEditForm.html', {'form': form}) Forms.py class Producteditform(forms.ModelForm): class Meta: model = Product fields = '__all__' class Warehouseeditform(forms.ModelForm): class Meta: model = Warehouse fields = '__all__' Models.py class Warehouse(models.Model): owner = models.ForeignKey(Employee, on_delete=models.CASCADE, related_name='employee_warehouse_owner') warehouse_name = models.CharField(max_length=500, default=0) warehouse_email = models.EmailField(max_length=500, default=0) warehouse_contact = models.CharField(max_length=500, default=0) class Product(models.Model): product_id = models.IntegerField(default=0) product_quantity = models.IntegerField(default=0) product_hsn_code = models.IntegerField(default=0) product_owner = models.ForeignKey(Employee, on_delete=models.CASCADE, related_name='product_owner') When I edit a product it saves the form without any error but when i try to do the same with warehouse it refreshed without any error and was not proceeding. Then with {{ form.errors }} it says : owner This field is required. Why does it need owner in the warehouse edit form but not in the product edit form ? -
