Gunicorn service fails to start
Gunicorn not starting Hi, I expect this is not the right subreddit for this unfortunately, but becuse it is a django application I've come here as a starting point. But for some reason, gunicorn service will not start on one of my servers. The gunicorn.service and the gunicorn.socket files are identical and in identical locations (I am building a staging server so it must be as close to the other one as possible, the other one is running fine). Can anyone see what might be the issue gunicorn.service: #!/bin/sh [Unit] Description=gunicorn daemon Requires=gunicorn.socket After=network.target [Service] User=pcc Group=nginx WorkingDirectory=/home/rob/myproject ExecStart=/home/rob/anaconda3/envs/django_env/bin/gunicorn --workers 3 --bind unix:/run/gunicorn.sock myproject.wsgi:application [Install] WantedBy=multi-user.target gunicorn status: (django_env) [rob@pcc-home-page run]$ sudo systemctl status gunicorn ● gunicorn.service - gunicorn daemon Loaded: loaded (/etc/systemd/system/gunicorn.service; disabled; vendor preset: disabled) Active: failed (Result: exit-code) since Wed 2020-03-11 12:45:25 UTC; 13s ago Process: 1466 ExecStart=/home/rob/anaconda3/envs/django_env/bin/gunicorn --workers 3 --bind unix:/run/gunicorn.sock myproject.wsgi:application (code=exited, status=203/EXEC) Main PID: 1466 (code=exited, status=203/EXEC) Mar 11 12:45:25 pcc-home-page.novalocal systemd[1]: Started gunicorn daemon.

Django - check if two password hashes are of same raw password
I want to keep track of user password change history, and display a warning if their current password is used by them before. To note, I don't want to prevent a user from setting a password if it is used before, I want to let them set the password, but just display a warning afterwards. So what I'm looking for is NOT a password validator. I know that while Django saves user passwords in the db, it creates a hash of the password, using a random salt. So 2 hashes of the same password will not be the same. Still, is it possible to tell if 2 different password hashes are created with the same raw password as the input? -
Django template - iterate a list of tuples, each tuple is a string, dictionary
I have a dictionary that has been turned into a sorted list, which creates the below: monthly_spend_provider = sorted(monthly_spend_provider.items(), key=lambda item: item[1]['cost'], reverse=True) monthly_spend_provider [ ('PROVIDER A', {'cost': Decimal('10000'), 'symbol': '£'}), ('PROVIDER B', {'cost': Decimal('9000'), 'symbol': '$'}), ('PROVIDER C', {'cost': Decimal('8000'), 'symbol': '$'}), ('PROVIDER D', {'cost': Decimal('7000'), 'symbol': '£'}), ] now im trying to access the data in the tuples in a Django template thus far unsucessfully. I thought the below would of worked but it hasn't {% for provider in monthly_provider_country %} {% for data in provider %} <h3>{{ provider }} {{ data.symbol }} {{ data.cost|currency }}</h3> {% endfor %} {% endfor %} can I do this in a template or is there a way to turn the sorted list back into an easier format to output into a template? Thanks -
How to add model form field in the constructor?
I am trying to add a field in a ModelForm but only if a certain condition is met, which is passed through the constructor, so I can't just do: class MyForm(models.ModelForm): class Meta: model = MyModel fields = ['myfield'] I know I can manually add it like this: class MyForm(models.ModelForm): def __init__(self, condition, *args, **kwargs): if condition: self.fields['myfield'] = forms.CharField() But that would be missing attributes from the model definition (max_length, help_text, validators...), not to mention the actual initial and data values if the instance exists. PS: yes I'm on Django 1.8, don't ask why. -
Django Model validation based on a field value of another Model
I have this Django model: from accounts.models import Account class BankOperation(models.Model): created_at = models.DateTimeField(auto_now_add=True) account = models.ForeignKey(Account, on_delete=models.CASCADE) operation_import = models.FloatField(default=0.0) I want to make sure that the operation_import is not higher than account.balance what is the official way to this? I have seen some answers talking about overriding the save() method but others advise against it. should i add a pre-save signal and throw some kind of exception? Is there a way to create a field validator that accepts parameters? so maybe something like: def validate_bank_operation_import(value, account_balance): if value > account_balance: raise ValidationError("Bank operation import is higher than account balance!") and inside my model i change the field to: operation_import = models.FloatField(default=0.0, validators=[validate_bank_operation_import]) But can i pass parameters to a validator? if yes, how do I do it? perhaps there is another to do this validation! -
Setting the field value of a form in view.py
My django website would like to allow logged in users to post a recipe. The recipe model is linked to the user model and as such requires a valid user instance. I would like the Recipe form to automatically assign the postedby field to the instance of the logged in user. So far I have attempted to pass in a dictionary, storing the user's name, to the form instance. as shown in the view However, the constructor method is not receiving the data and is rendering the form but with a failed attempt to submit. I cannot store the data without postedby field having a valid instance as the model throws the following error: Exception Value:UserProfile matching query does not exist. I have also tried to do the following in views.py; @login_required def add_recipe(request): form = RecipeForm() form.fields['postedby'] = UserProfile.objects.get(user=User.objects.get(username=request.user.__str__())) context_dict = {'form':form} if request.method == 'POST': ... However this overwrites the postedby form view to be rendered and raises and error. views.py @login_required def add_recipe(request): form = RecipeForm({'user':request.user}) context_dict = {} #print(form.fields['postedby'].queryset) if request.method == 'POST': form = RecipeForm(request.POST) if form.is_valid(): form.save(commit=True) return redirect(reverse('spatula:index')) else: print(form.errors) context_dict['form'] = form return render(request, 'spatula/add_recipe.html', context=context_dict) The RecipeForm is as follows: class … -

Django models foreignkey default value
There was no manager in the posts I created before. When I add the manager, I want the default value or I am asked to enter it manually. When I enter 'None' I get an error like this; django.db.utils.IntegrityError: NOT NULL constraint failed: new__Core_post.manager_id I cannot export PostManager as the default value.

How to get only one object from ManyToOne table, instead of queryset?
Table Images: id| image | item_id 15|some/path| 45 16|some/path| 45 17|some/path| 45 First try: recommended_items = Item.objects.all().filter(rating__gte=9) // All my items (`item_id` column) for item in recommended_items : image = Images.objects.get(item=item.id)[:1] It works for first item with id=45 but for the rest it returns error: Images matching query does not exist. Second try: for item in recommended_items : image = Images.objects.filter(item=item)[:1] Now it works for all items, existing or not, but it returns iterate object and I should add for loop for just one object, like this: for i in image: print(i.image) What is the right way to handle this ? I want just one record (the last one if it is possible) -

Django Choice Field similar as in Admin (Permissions)
Unfortunately we have some really long drop down lists for our users to choose from and the way the django admin implemented their permissions ui really looks like a good solution for this, but for the life of me I can't find any examples how to implement something similar?

NOT NULL constraint failed: complaint_complaint.resident_id
I am writing an app in which people can submit their complaints related to some issues. After the form is submitted, it is supposed to redirect to the page where the details of the complaint are mentioned like area of the complaint, title, description etc. But after the form is submitted, it throws IntegrityError. I read about it and went through some of the solutions: Someone suggested that I delete some past migrations and run them again. I cleared the migrations, ran them again and made some posts through the admin but it is throwing the same error. Some posts suggest that null=True, blank=True should be added but I do not understand where they should be added in my case. I also don't want to add null=True, blank=True because I don't want any field to be left blank.
