django -decorators - wrapper function missing 1 positional argument
I'm trying to add some custom made decorators to my class baseds views, but I get this strange error: TypeError at /equipment/ wrapper_func() missing 1 required positional argument: 'request' This is my decorator (just the general structures, with a print test): def allowed_users(allowed_roles=[]): def decorator(view_func): def wrapper_func(request, *args, **kwargs): print('working:', allowed_roles) return view_func(request, *args, **kwargs) return wrapper_func return decorator and this is the view: class EquipmentType_ListView(LoginRequiredMixin, ListView): model = EquipmentType template_name = 'equipment/equipmentType_list.html' context_object_name = 'obj_list' ordering = ['type'] @method_decorator(allowed_users(allowed_roles=['Direzione'])) I don't understand what is missing, the wrap_func as the request parameter, but still the error says it is missing. Any help? Thank you Carlo -
How to start django web application under apache 2.4 vhost
If my apache service gets stopped I have realised I need to run source /opt/django/webapp/bin/activate; apachectl start as the user that installed the app to get the web service working correctly. How can I fix this so that if a reboot happens or apache stops it would just work when I run apachectl start. I am working on amazon ec2 instance. I have put the below in but does not seem to work cat <<EOT >> /etc/init.d/mystartup.sh #!/bin/bash source /opt/django/webapp/bin/activate; apachectl start EOT chmod +x /etc/init.d/mystartup.sh echo /etc/init.d/mystartup.sh >> /etc/rc.local -
Django and SQL Server, gevent compliant
I would like to use a SQL Server database in a Django app that I can scale in the future. The app would be I/O bound, so I thought the best way to make it scalable is to use Gunicorn with the gevent worker class. The problem is that for using Gunicorn with --worker-class gevent the Django app should be gevent compliant and usually happens that some database clients aren't compatible (eg: mysqlclient lib). I found this SQL Server backend for Django: https://pypi.org/project/django-mssql-backend/ but I'm not able to understand if it is gevent compliant (aka "green"). I know that it would be so if it only uses standard socket/networking python libs that can be easily monkey-patched but I can't understand if this is the case. Is pyodbc SQL Server backend gevent compliant? On the official manual and on Google I can't find further information. -

Django: Subprocess Continuous Output To HTML View
I need a HTML webpage in my Django app to load and show the continous output of a script in a scrollable box. Is this possible? I'm presently using a subprocess to run a Python script, but the HTML page won't load until after the script has finished (which can take about 5 minutes). I want the users to see something is happening, rather than just a spinning circle. What I have already also unloads the full output of the script with "\n" in the text; I'd like it to output each new line instead, if possible. My code is as follows: Views.py: def projectprogress(request): GenerateProjectConfig(request) home = os.getcwd() project_id = request.session['projectname'] staging_folder = home + "/staging/" + project_id + "/" output = "" os.chdir(staging_folder) script = home + '/webscripts/terraformdeploy.py' try: output = subprocess.check_output(['python', script], shell=True) except subprocess.CalledProcessError: exit_code, error_msg = output.returncode, output.output os.chdir(home) return render(request, 'projectprogress.html', locals()) projectprogress.html: <style> div.ex1 { background-color: black; width: 900px; height: 500px; overflow: scroll; margin: 50px; } </style> <body style="background-color: #565c60; font-family: Georgia, 'Times New Roman', Times, serif; color: white; margin:0"></body> <div class="ex1"> {% if output %}<h3>{{ output }}</h3>{% endif %} {% if exit_code %}<h3> The command returned an error: {{ error_msg }}</h3>{% endif … -
How to get approval for a particular task in django
I am working on creating tasks, in which I require have a url for approvals. In this, the person that created the task instance can ask for approval for some changes from another user (not necessarily admin). These approval requests will show up on the approver's dashboard in form of a table, where he can approve/reject them. Here is my code: models.py: class Approvals(models.Model): task = models.ForeignKey(Task_category, on_delete=models.CASCADE) requester = models.ForeignKey(User, related_name='Requester', on_delete=models.CASCADE) priority = models.CharField(max_length=50) approver = models.ForeignKey(User,related_name='Approver', on_delete=models.CASCADE) description = models.CharField(max_length=400) created_at = models.DateTimeField(auto_now_add=True) due_date = models.DateField(null=True,blank=True) approved = models.BooleanField(default=False) views.py: class PendingApprovals(viewsets.ModelViewSet): http_method_names = ["get","update"] queryset = Approvals.objects.all() serializer_class = ApprovalSerializer to_approved = Approvals.objects.filter(approver=request.user,approved='False') I am able to get a list of all the tasks that a given user has to approve, but I cant figure out how to approve them i.e how to change their boolean field tag. Any help will be appreciated. TIA. -

React Const Infinite Cycle
I faced a problem when I was coding in React. I have the following segment of code: <Popconfirm placement="topRight" title="Are you sure to delete this task?" onConfirm={confirm} okText="Yes" cancelText="No" // [1] > <a>delete</a> </Popconfirm> and I have the confirm function like this: const confirm = () => { // [2] message .loading("Deleting...", 1.8) .then(() => message.success("Todo item deleted!", 1.3)); postDeleteData('/todo/', { method: 'delete', keyid: 42}) // [3] .then(data => { if (data.success) {window.location = '/todo/';} }) console.log('confirmed'); }; Now, everything works fine so far. However, things won't work after I made the following changes: Changed confirm to confirm(42) (just as a test) Changed confirm = () => to confirm = (kid) => Changed {keyid: 42} to {keyid: kid} Which basically passes a parameter to the confirm call. I was expecting everything to work smoothly as this happened: And as you can see, the code started to execute infinitely on itself automatically without any key presses or action, which is the problem. Can anyone please tell me the cause? Thanks in advance.

Using a serializer to validate data in a custom django REST API view
I am trying to build a custom API view and I stumbled over 2 problems, one more general, the other one more specific: I have a custom view where I create a an object from the data sent in the api-request: @api_view(["POST"]) def graph_create_view(request): """ """ network = Network.objects.get(name=request.data["network"]) graph = Graph.objects.create( network_id=network.id, name=request.data["name"], description=request.data["description"], field2==request.data["field"], field3==request.data["field"], field4==request.data["field"], field5==request.data["field"], field6==request.data["field"], field7==request.data["field"], graph.save() return Response(HttpResponse.status_code) That works well, when I send all the data specified in the Graph.objects.create method. When I do not send all the data but leave out a field (Let's say I send for example data without the description field) I get a key-error. That makes sense, because that key is actually missing. I could circumvent this with many if-else-statements but that is cumbersome, not practical and hard to maintain. Now, I know I probably should write a generic view and not build this myself like this. The problem is that I need to create a Graph with two nested serializers attached to it and this is quite complicated to implement when overwriting the create method. Because the graph has two more models related to it for which I also create objects and then add it to the … -

Automatically create Item in reverse foreign table if not exist in django rest frameworks
Suppose I've model as shown below. class Estimate(models.Model): company = models.ForeignKey( settings.CompanyInfo, on_delete=models.CASCADE, related_name='company' ) and the company model is class CompanyInfo(models.Model): name = models.CharField(_("Name"), max_length=255) email = models.EmailField(_("Email"), max_length=254) address = models.CharField(_("Address"), max_length=255) if i follow documentation as suggested here, https://www.django-rest-framework.org/api-guide/relations/#writable-nested-serializers i can able to create foreign table data, But i want this in reverse order. Let me clarify more. Suppose user want to create new estimate object. each time user create new object user is also providing all the information which is required to create company info. I hope this sentence make some sense. Now my requirement is if the company already exist, I just want to use company id in estimate table, other wise create new company and assign its id for new estimate object. Also I'm not sure either this is possible or not so I'm really sorry for this stupid question. -

It should auto increase from there, so if user A stays idle but user B makes other submits, B's next will get 000002, 000003 etc. If user C then joins and submit, he should get 000001 too. How would I approach this? my models: class Account(AbstractBaseUser): email = models.EmailField(verbose_name='email', max_length=60, unique=True) username = models.CharField(max_length=30, unique=True) first_name = models.CharField(max_length=25) last_name = models.CharField(max_length=45) date_joined = models.DateTimeField(verbose_name='date joined', auto_now_add=True) last_login = models.DateTimeField(verbose_name='last login', auto_now=True) is_active = models.BooleanField(default=True) is_admin = models.BooleanField(default=False) is_staff = models.BooleanField(default=False) is_superuser = models.BooleanField(default=False) # Company Profile Fields co_logo = models.ImageField(upload_to="dashboard/logos", blank=True) co_name = models.CharField(max_length=45) co_address = models.CharField(max_length=45) co_zip = models.CharField(max_length=45) co_city = models.CharField(max_length=45) objects = MyAccountManager() USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['username'] def __str__(self): return self.email def has_perm(self, perm, obj=None): return self.is_admin def has_module_perms(self, app_label): return True class Invoice(models.Model): client = models.ForeignKey(BusinessContact, default=None, on_delete=models.CASCADE) user = models.ForeignKey(Account, default=None, on_delete=models.CASCADE) invoice_id = models.CharField(unique=True, max_length=6, null=True, blank=True, editable=False) place = models.CharField(max_length=40) date_created = models.DateTimeField(verbose_name='date created', auto_now_add=True) date_sent = models.DateTimeField(verbose_name='date sent by mail', auto_now=True) date_deadline = models.DateTimeField(verbose_name='payment deadline', auto_now=False) bank_number … -
How to make a unite test for mocking a random return funciton?
I need to mock the output of this function: utils/generate_new_verification_token.py from random import randint def generate_new_verification_token(): return ''.join(["{}".format(randint(0, 9)) for num in range(0, 4)]) In my test file: x/test_api.py class TestPhoneVerify(APITestCase): def setUp(self): self.user = User.objects.create_user(email='mock@example.com', password='12345678') def generate_token(): foo = ['1111', '2222'] return Response(random.choice(foo)) @mock.patch('utils.generate_new_verification_token.generate_new_verification_token', side_effect=generate_token) def test_duplicate_code_for_same_user(self, req_token): self.client.force_login(self.user) res_request = self.client.post('/phone/request/', data={'phone': '4545345'}) print(res_request.token) It keeps generating random numbers other than '11111', '2222' which I am using in the mocking function. i.e it keeps using the original generate_new_verification_token function. How to solve this to use my generate_token mocking function? -
django nested model json import
I am quite new to Django and I may be missunderstanding some concepts, but I can not find a solution to what I am trying to do. I have a multi table model defined and I have defined the models, views, admin, serializers and urls. It is working perfectly to independtly read and write in all of them through the API. The code looks something like this: models.py class Level1(MySQLNoCountModel): name = models.CharField() ... class Level2(MySQLNoCountModel): level1 = models.ForeignKey( Level1, blank=False, null=True, on_delete=models.CASCADE ) name = models.CharField() ) ... serializers.py class CreateLevel1Serializer(OrderedModelSerializer): name = serializers.CharField() def create(self, validated_data): obj, created = models.Level1.objects.update_or_create( name = validated_data['name'], defaults={ } ) class CreateLevel2Serializer(OrderedModelSerializer): level1 = serializers.CharField() name = serializers.CharField() def validate_level1(self, value): try: return models.Level1.objects.get( name=value ) except Exception: raise serializers.ValidationError(_('Invalid leve1')) def create(self, validated_data): obj, created = models.Level2.objects.update_or_create( name = validated_data['name'], defaults={ 'level1': validated_data.get('level1', True), } ) With this I can create new elements by sending two consecutive posts to the specific ednpoints: { "name":"name1" } { "level1":"name1", "name":"name2" } I am trying to do it in a single operation by inserting something like this: { "name":"name1" "level2":[ { "name":"name2" }, { "name":"name3" } ] } I have tryied to redefine the …
