foreign key showing undefined django ajax
in this scenario when put the name of foreign key in p tag with js, it is showing undefined but its getting the inpuput as the proper user but not not able to show it because it is saying undefined js code $(document).ready(function(){ // $('#submit').onclick(function(){ // $('#message').val='' // }) $(document).on('submit','#post_form',function(e){ e.preventDefault(); $.ajax({ type: 'POST', url:"{% url 'create' %}", data:{ message: $('#message').val(), csrfmiddlewaretoken:$('input[name=csrfmiddlewaretoken]').val(), }, success:function(){ window.location = url; } }); }); setInterval(function() { $.ajax({ type:'GET', url:"{% url 'comments' %}", success:function(response){ $('.display').empty(); for(var key in response.comments){ this is where it shows undefined, is there any way to convert it to string console.log(response.comments[key].user); var temp = "<div class='message_area'><p id='messagetext'>"+response.comments[key].message+"</p></div>" $(".display").append(temp); } }, error:function(response){ console.log("no data found") } }); }, 500); }); views.py def create(request): if request.method == "POST": author = request.user message = request.POST['message'] message = comments(user=author,message=message) message.save() models class comments(models.Model): userId = models.AutoField(primary_key=True) user = models.ForeignKey(User,on_delete=models.CASCADE) message = models.CharField(max_length=100,blank=False) date = models.TimeField(auto_now_add=True) def __str__(self): return f'{self.user} comments' -
Which is First and All?
I read the Django documentation, but I'm not sure if I'm doing it right. What I want to do: I want to get all the user's posts through his id, because it will be a platform that will have profiles of users of various types. I did it this way to return the user's posts: user = Post.objects.filter(user=id).all() But I saw that there is another way to do it, so I was seeing it on facebook groups. users = Post.objects.filter(user=id).first() Which of the two ways are correct to be done? OBS: I want to return all user posts! -
Overlap in drop down button in HTML code using JQUERY
Drop Down1: Work County1: INDIA Work State1: Drop Down2: Work County2: INDIA Work State2: CHN I have coded drop down logic. Scenario1: selected Country1 India and state as chennai. Scenario2: Selected country2 USA and state is TX. Scenario3: Selected country 2 as India and state is Chennai.But it impacted the drop down 1 by making the state as blank. My doubt is drop down1 and drop down 2 should be independent of each other but scenario3 stated above occurs. My code snippet is below. <!DOCTYPE html> <html> <head> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script> <script> $(document).ready(function() { var $select1=$('#select1'), $select2=$('#select2') $options=$select2.find('option'); $select1.on('change',function() { $select2.html($options.filter('[value="'+this.value+'"]')); }).trigger('change'); } ); </script> <script> $(document).ready(function() { var $select3=$('#select3'), $select4=$('#select4') $options=$select4.find('option'); $select3.on('change',function() { $select4.html($options.filter('[value="'+this.value+'"]')); }).trigger('change'); } ); </script> <title>Page Title</title> </head> <body> <tr> <td><label for="appt">Work County1:</label></td> <td><select id="select1"> <option selected disabled="true" value="">------</option> <option value="1">INDIA </option> <option value="2">USA </option> </select><br></td> <td><label for="appt">Work State1:</label></td> <td><select id="select2"> <option selected disabled="true" value="">------</option> <option value=1>CHN</option> <option value=2>TX</option> </select><br></td> </tr> <br><br><br><br> <tr> <td><label for="appt">Work County2:</label></td> <td><select id="select3"> <option selected disabled="true" value="">------</option> <option value="1">INDIA </option> <option value="2">USA </option> </select><br></td> <td><label for="appt">Work State2:</label></td> <td><select id="select4"> <option selected disabled="true" value="">------</option> <option value=1>CHN</option> <option value=2>TX</option> </select><br></td> </tr> </body> </html> -

Add new ports like 8081 in cloudflare
I have two Django project running on port 8080 and 8081 with named domain name abc.com Now we added our website to Cloudflare so abc.com with new IP with port 8080 is working fine But, on port 8081 we can access it via the only original_host_ip and not the domainname.com i.e abc.com:8080 WORKING a.b.c.d:8081 WORKING I tested it via Test-NetConnection a.b.c.d -port 8081 Test-NetConnection abc.com -port 8081 abc.com:8081 NOTWORKING ->Remote address cloudflare a.b.c.d:8081 WORKING ->Remote address a.b.c.d So I thought it is maybe due to the firewall of Cloudflare that it is not accepting port 8081 So I want to know how to add a new port to Cloudflare like port 8081. -
How is Django makemigrations triggered for changes to a custom model field?
I have a custom model field defined as: class PriceField(models.DecimalField): def __init__(self, *args, **kwargs): kwargs['max_digits'] = 30 kwargs['decimal_places'] = 20 super().__init__(*args, **kwargs) I want to change it so that it is also nullable/blankable so I add: class PriceField(models.DecimalField): def __init__(self, *args, **kwargs): kwargs['max_digits'] = 30 kwargs['decimal_places'] = 20 kwargs['null'] = True kwargs['blank'] = True super().__init__(*args, **kwargs) However, having made this addition and running makemigrations, no new migrations are created. Having read the documentation at https://docs.djangoproject.com/en/3.1/howto/custom-model-fields/#field-deconstruction I thought that the problem might be the lack of a deconstruct() method, but even after adding one as seems to be described in the docs (which I read as being to delete the kwargs you override in the init method): def deconstruct(self): name, path, args, kwargs = super().deconstruct() del kwargs['max_digits'] del kwargs['decimal_places'] del kwargs['null'] del kwargs['blank'] return name, path, args, kwargs ...it still doesn't create any migrations to make the field nullable/blankable. Can anyone tell me what I'm missing? -
How to render a string/dict in views.py with gettext_lazy before sending to rendering in Django
I am currently looking for a possibility to render a string using elements that need to be translated and using gettext_lazy. Lets assume following: My dict data: from django.utils.translation import gettext_lazy as _ data = { "name": _("Invoice"), } I want to pass this data to requests to do an API call, like this. response = requests.post('https://someapi.com/call', headers=settings.AUTH_HEADERS, json=data) If I do this, I get an error, as the gettext_lazy is only proxy at this point. Grateful for any hint. -
Why does my django webserver stop after trying to send password reset mail

Django 3.1.5 and Channels 3.0.3 websocket problem
I am migrating an app to Django 3.1.5 and channels 3.0.3 and I am having problems with websockets getting disconnected around 2 seconds after being connected. This is my consumer and it gets connected but a few seconds later, it disconnects without triggering the disconnect from channels.generic.websocket import JsonWebsocketConsumer from django.utils import timezone from asgiref.sync import async_to_sync class SystemConsumer(JsonWebsocketConsumer): groups = ["WSbroadcast","WSsystemAPP"] def connect(self): self.accept() print('Websocket accepted: ' + str(self.scope)) def disconnect(self, close_code): # Called when the socket closes print('Websocket disconnected: ' + str(close_code)) Can anyone tell me what can it be failing here?? I guess if the websocket connects, the routing and all the stuff is OK, but it disconnects without any advise... Thanks!! -

Reading data from Javascript Promise
I'm using the django framework and I'm trying to get the data from a Javascript Promise as follows: Js file console.log("working"); $("#username").keyup(function(event){ let user=event.target.value fetch("/login/userValidation/",{ body:JSON.stringify({username:user}), method:"POST" }).then((res)=>{ console.log(res.json()); }); }); Py file (views.py) from django.contrib.auth.models import User from django.http import JsonResponse as jresp from django.views import View import json class userValidation(View): def post(self,req): data=json.loads(req.body) user=data['username'] print(user) if(user.isalnum()): if(User.objects.filter(username=user)): print("Username not available") return jresp({"user_status":"Username not available, try something else"}) else: print("Username Valid") return jresp({"user_status":"Username Valid"}) else: print("Please enter alphanumeric characters only") return jresp({"user_status":"Please enter alphanumeric characters only"}) Fetch() is posting the data from the client side to the server and the server is receiving the data just fine, as I have checked by printing out the data in the backend. However, the JsonResponse that is being returned to the client is showing undefined instead of the actual data - I'm not able to get the required data from the promise, using response.json() under the subsequent then() function.

so i created a simple blog, tried deploying with heroku(it just told me application error), so now i tried with python everywhere.

Django show save buttons for nlineModelAdmin not the main ModelAdmin?
I am not giving users the permissions to change the main modelAdmin. However I am allowing them to add a record to the InlineModelAdmin. Unforutnately the save button does not show. I tried overriding the method: def has_change_permission(self, request, obj=None): '''Show the save button''' return True That shows the save button but now gives the user permission to change the main model. It seems that this context variable has_editable_inline_admin_formsets in django/contrib/admin/templatetags/admin_modify.py is set to false. Even though the inline formset is editable. After a deeper dive it looks as though this section of code on line 1486 of django/contrib/admin/options.py overrides everything to false if you cannot edit the parent. if can_edit_parent: has_add_permission = inline.has_add_permission(request, obj) has_change_permission = inline.has_change_permission(request, obj) has_delete_permission = inline.has_delete_permission(request, obj) else: # Disable all edit-permissions, and overide formset settings. has_add_permission = has_change_permission = has_delete_permission = False formset.extra = formset.max_num = 0 So what should I do to allow for adding and deleting of the inline - I assume all that needs to be done is override the template in templates/admin/app_name/model_name_change_form.html and change this row to always show save: {% block submit_buttons_bottom %}{% submit_row %}{% endblock %} to: {% block submit_buttons_bottom %} {% submit_row %} <input type="submit" value="Save" … -
Is Django Apache or Nginx

When I run code in Docker I get a Django error [Errno 2]. When running locally everything works. Why?
I don't know what's going on. A script run by Django works fine, but not through Docker and Django. An error is returned: Pic Errno 2 No such file or directory Below is the code of the function with the error and the code of the Dockerfile.

Duplicate key error when saving a new object
I'm creating a new object with a form and when I hit the save button I got this error: IntegrityError at /department/add duplicate key value violates unique constraint "feedback_department_pkey" DETAIL: Key (id)=(1) already exists. Although, I have 18 records in this table in the database, but I can't figure out why is trying to start saving from the first id. my views.py: # Add new department def department_add(request): form = DepartmentEditForm() if request.method == "POST": print('Printing POST', request.POST) form = DepartmentEditForm(request.POST) if form.is_valid(): form.save() return redirect('feedback:department') return render(request, 'departmentadd.html', {'form': form}) my models.py: class Department(models.Model): name = models.CharField(max_length=100) title_bg = models.CharField(max_length=50) title_en = models.CharField(max_length=50) title_de = models.CharField(max_length=50) def __str__(self): return self.name urls.py path('department/add', views.department_add, name="departmentadd"), and forms.py: class DepartmentEditForm(forms.ModelForm): class Meta: model = Department #fields = '__all__' fields = [ 'name', 'title_bg', 'title_en', 'title_de', ] widgets = { 'name': forms.TextInput(attrs={'class': 'form-control'}), 'title_bg': forms.TextInput(attrs={'class': 'form-control'}), 'title_en': forms.TextInput(attrs={'class': 'form-control'}), 'title_de': forms.TextInput(attrs={'class': 'form-control'}), } Can someone say what I'm missing here? Thanks a lot! -
Django logging still prints out stacktrace
For some reason instead of just printing out the error message with logging it prints the stack trace to the console followed by the message: LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'formatters': { 'standard': { 'format': '[%(asctime)s] p%(process)s {%(pathname)s:%(lineno)d} %(levelname)s - %(message)s', }, }, 'handlers': { 'default': { 'level': env.str('LOGGING_LEVEL'), 'class': 'logging.StreamHandler', 'formatter': 'standard', }, }, 'loggers': { 'default': { 'handlers': ['default'], 'level': env.str('LOGGING_LEVEL'), 'propagate': True }, } } from logging import getLogger log = getLogger('default') def test(): try: raise Exception('This is a test exception') except Exception as error: log.error(str(error)) output: $ python manage.py custom_test_command # calls test method ... raise Exception('This is a test exception') Exception: This is a test exception [2021-02-08 16:27:40,299] p21052 {<console>:4} ERROR - This is a test exception
