Nginx Permission Denied but has permission (nginx, gunicorn, django)
I have tried to get rid of the error message for over 6 hours, but I can't still figure it out. At First, I had my Django+React project directory at /home/pi/pidjango and I got a 403 Forbidden(css, js) Error message from Nginx, so I searched for a long time and I moved my project (pidjango) to /home/pi/.local/share and it seemed to be fine. Then I got a 502 Bad Gateway Error, and also fixed that (It was a problem from nginx) and I got 403 error again. It is the error about nginx not getting static files(css, js) and I gave chmod 755 (-rwxr-xr-x) and it still doesn't work. Can anybody solve this? Thank you.

How to properly add a m2m 'through' field in django models? Now I am getting this error: 'M2M field' object has no attribute '_m2m_reverse_name_cache'

How to make the 'return' from a django model conditional to the value of a global variable?
I am a novice in both Python and Django, and I am struggling to find the way to make a 'return' from a Django model conditional upon the value of a global variable. More specifically, I am designing an app to run an interview with the user / visitor. In the interview the questions to the user can be in past or present tense. This depends on an introduction view from which I get the choice from the user, i.e. either 'past' or 'now'. My model is class Question(models.Model): key = models.CharField(max_length=50) value = models.CharField(max_length=50) question_text_past = models.CharField(max_length=2000) question_text_now = models.CharField(max_length=2000) def __str__(self): global TENSE if TENSE == 'past': return self.question_text_past else: return self.question_text_now However, no matter what I've tried (while testing the code within the shell), my model does not reflect the changes in the value of TENSE. The model returns a "not defined" error. I've also tried to put TENSE into a module globals.py and import this into my models.py with no success. I might be missing something simple but fundamental about Django, so I appreciate any help. -

Is this the correct gist of how to use Django Simple JWT?
The client will be Android Use username and password via POST to /thetokenurl to get access and refresh token, store access and refresh token in local storage Use token in auth header for any API call to protected endpoint Whenever frontend needs API call, you always have to do if/else work to check if the response say something about token being expired, and if its expired, then use the refresh token from local storage to get a new access token, and then store new access token in local storage and then make the API call to whatever you want. -

Field-level validation for DRF HiddenField in update
What is the correct way to do field-level validation on DRF serializers.HiddenField() ? What I tried (Assuming field name is x): Adding a validate_x() method to the serializer class. This method is not being called in partial update action (HTTP PATCH). Trying to validate it in validate(self, data) method. It does not exist in data dictionary. What is the correct way to add custom validation for this in partial update?

I am not sure how to take form.is_scholorship as tag and pass to javascript function to set next field show/hide or do more actions with this variable. Here is my code. In the template: <div class="form-group col-md-6"> {{ form.non_field_errors }} <div class="fieldWrapper"> {{ form.is_scholorship.errors }} <label class="form-label">獎學金</label> {{ form.is_scholorship }} <button type="button" onclick="test()"> 測試 </button> </div> </div> <div class="form-group col-md-6"> {{ form.non_field_errors }} <div class="fieldWrapper"> {{ form.scholorship_amount.errors }} <label class="form-label">獎學金金額</label> {{ form.scholorship_amount }} </div> </div> In the models.py: class Case(models.Model): . . . is_scholorship=models.BooleanField(verbose_name="獎學金",default=False) scholorship_amount=models.IntegerField(verbose_name="獎學金金額",blank=True,default=0,null=True) Also, I want to check whether onclick() works. I did the code <script> function test(){ console.log("test"); //var a= "{{ form.is_scholorship }}"; //alert("a:",a); } $('#id_is_scholorship').click(function(){ alert("test"); }); </script> <button type="button" onclick="test()"> 測試 </button> But it showed an error about Uncaught ReferenceError: test is not defined So does Django not to use javascript like this way? Hope someone can help me to figure out handling Django variable in javascript. Thank you for your time. -
How load foreingkey in admin site Django
I'm trying to change the way to load models on the admin page, especially foreign keys, because I have a delay to load them, the option for this was to exclude the field, but I want to have another option, thanks # model.service.py class Service(BaseModel): # Service data client = models.ForeignKey(Client, on_delete=models.CASCADE, null=True) Any = models.CharField()... # service_form.py class ServiceForm(forms.ModelForm): class Meta: model = models.Service exclude = ["client"] # admin.py class serviceAdmin(admin.ModelAdmin): model = models.service admin.site.register(models.service, ServiceAdmin) this way I exclude the field for loading, but is there a way to do it that doesn't take so long to load?
