Django create a new column in an already existing table
I'm using Django 3.0.5 and I am trying to create a new column in a table. The table looks like this: class VacationModel(models.Model): first_name = models.CharField(max_length=100) last_name = models.CharField(max_length=100) emp_id = models.IntegerField() email = models.EmailField() from_date = models.DateField() to_date = models.DateField() reason = models.TextField() time_sent = models.DateTimeField("date sent") req_approved = models.BooleanField(default=False, null=True) req_denied = models.BooleanField(default=False, null=True) # daysoff_given = models.IntegerField() def __str__(self): return self.emp_id The new column would be daysoff_given. I tried adding this column and after running python manage.py makemigrations I got an error saying django.db.utils.OperationalError: no such column I tried following some other answers and I deleted the migrations made inside the mirgations folder, without deleting the __init__.py file. After running makemigrations again the same error occured and then I deleted the whole model and made a new model. I think my database is broken, but is there an actual way to avoid this, since it has already happened 2 times. Whenever I try to add a new column, it always throws that error and I cannot continue. How can I fix this? -
Django and Vue.js with Axios: 500 internal server error with post request
I am currently making a TODO app with Vue.js and Django (Vanilla Django not the Django REST framework) and I am using AXIOS to perform the request post/get, the get request works perfectly fine and I am able to fetch data, but when I create a new task and submit it to the Django I get this error on the front end: xhr.js:185 POST http://127.0.0.1:8000/tasks/ 500 (Internal Server Error) createError.js:17 Uncaught (in promise) Error: Request failed with status code 500 at createError (createError.js:17) at settle (settle.js:18) at XMLHttpRequest.handleLoad (xhr.js:69) Here is my code in the front end HTML and javascript: function sendRequest(url, methode, data) { const r = axios({ url: url, method: methode, data: data, xsrfCookieName: 'csrftoken', xsrfHeaderName: 'X-CSRFToken', headers: { 'X-Requested-With': 'XMLHttpRequest' //to allow django recognizing this request as ajax request } }); return r; } const app = new Vue({ el: '#app', data: { task: '', tasks: [], }, //use hooks to call the function at the event of page loaded created() { const vue_instance_ref = this; const r = sendRequest('', 'get') .then(function (response) { vue_instance_ref.tasks = response.data.tasks; }); }, methods: { createNewTask() { const vue_instance_ref = this; const formData = new FormData(); formData.append('title', this.task); sendRequest('', 'post', formData) … -
Can not seem to get Django to display the correct content in web-pages
I am creating a web-app using Django. I want the app to have 4 sections, the homepage, Culture, Entertainment, and Technology. The home page would display all the articles while the other pages would display articles that relate to that category. I created a class for all the articles. Some of the class objects are: category, title, by, summary. In views.py, for the homepage, I created a function to display all the articles in random order. I then created 3 more functions that display the articles by category. The problem is, the home page is the only one that works properly. I made links to all 4 pages in my navbar, all four links go back to my homepage instead of the category pages i made. The function I made for the homepage or all_blogs is the only one that works. When I modify it so it only displays articles in a certain category it works, but when I try to make a new function and new page, it only displays the homepage. views.py from django.shortcuts import render, get_object_or_404 from .models import Blog def all_blogs(request): blogs = Blog.objects.order_by('?') return render(request, 'blog/all_blogs.html', {'blogs': blogs}) def Entertainment(request): blogs = Blog.objects.exclude(category='Technology, Culture') return … -

Adding custom views to django admin interface to add more functionality
So I'm trying to extend Django's admin interface. I want to add more functionality to it without overriding it completely. I have a view in my app which returns a list of users who have registered in a particular time frame (last 24 hours e.t.c.) and also a toggle button which can deactivate or activate the users at will. The thing is, I initially created it with it's own template and everything, but now I don't want to reinvent the wheel and just want to add it to django's own admin interface. I've checked multiple solutions online, however they all involve using models, whereas I'm not trying to use any particular model. I just want to be able to pass context from my views to the template. So I'm trying to have something like in the image above, but in the django admin interface. Like just in a div below the other fields. Below are the views that display the data and the toggle buttons @staff_member_required def custom_admin(request): if request.user.is_staff: users_in_past_24_hours = CustomUser.objects.filter(created_at__gt=time_threshold(24)) users_in_past_week = CustomUser.objects.filter(created_at__gt=time_threshold(168)) users_in_past_month = CustomUser.objects.filter(created_at__gt=time_threshold(730)) context = {"users_in_past_24_hours": users_in_past_24_hours, "users_in_past_week": users_in_past_week, "users_in_past_month": users_in_past_month} else: return redirect('unauthorized') return render(request, 'admin_dashboard.html', context) @require_POST @staff_member_required def toggle_user_status_true(request, user_id): user … -
Django Custom UserAdmin wrong change user password URL
I'm doing some refactors on an application written in Django and I've noticed that the URL to change the password for the desired user is wrong in the link. Instead of /admin/myapp/user/<:id>/password/ the url on the link is /admin/myapp/user/<:id>/change/password/. If I go to /admin/myapp/user/<:id>/password/ I can see the password reset screen for django admin but the link to click is wrong.

How to solve this modelForm Django error?

Properly escaping strings in raw Django SQL query
Really the root of the problem is poor database design going back to long before I started here, but that problem isn't going to be resolved by the end of the day or even the end of the week. Thus, I need to find a better way to handle the following to get a feature added. I'm forced to deviate away from the Django ORM because I need to build a raw SQL query due to having to write logic around the FROM <table>. We've elected to go this route instead of updating the models.py a couple times a year with the new tables that are added. There are numerous areas starting here where the Django documentation says "Do not use string formatting on raw queries or quote placeholders in your SQL strings!" If I write the query like this: cursor.execute(""" SELECT * \ FROM agg_data_%s \ WHERE dataview = %s \ ORDER BY sortorder """, [tbl, data_view]) It adds single quotes around tbl, which obviously causes an issue, but will correctly construct the WHERE clause surrounded in single quotes. Doing this, will not put single quotes around tbl, but will force you to put single quotes around the WHERE … -
Cannot pass variables to Django 3 method from HTML template
I am a Django newbie who is trying convert and existing HTML based website to Django 3. The only complex piece of this page is a call to a Django method that uses the django.core.mail package and everything works, but, I am trying to pull some data off of the HTML template and pass it to this method. The method works only it sends a blank email. I am trying to pass contact information that the end user would fill out on the form. If I hard code the data into the method it works. I have tried passing the data through urls.py, but, everything I try fails to even parse when I call the method. When I use a request.GET.get everything seems to work, just no data. I was hoping to use some similar to JQuery like the following in the method. name = str(request.GET.get('Name:', '').strip()) email = str(request.GET.get('Email:', '').strip()) msg1 = str(request.GET.get('Message:', '').strip()) with the fields being in the HTML form.

Can't create a custom User model in django
I have a custom passwordless user model built in django 1.11. user model looks like this class User(models.Model): email = models.EmailField(primary_key=True) REQUIRED_FIELDS = [] USERNAME_FIELD = 'email' is_anonymous = False is_authenticated = True It's a custom user model and depends on a custom auth backend, given like this class PasswordlessAuthenticationBackend(): def authenticate(self, uid): try: token = Token.objects.get(uid=uid) return User.objects.get(email=token.email) except User.DoesNotExist: return User.objects.create(email=token.email) except Token.DoesNotExist: return None def get_user(self, email): try: return User.objects.get(email=email) except User.DoesNotExist: return None The auth is registered and working fine. The token is just this class Token(models.Model): email = models.EmailField() uid = models.CharField(default=uuid.uuid4, max_length=40) The problem is, when I try to call auth.login in my TestCase, it always throws this error: ValueError: The following fields do not exist in this model or are m2m fields: last_login What are m2m fields? How and where do I specify this last_login? -
forms.ValidationError bug?
this is my third day in django and I'm working on my validation form and i came across this weird bug where my validation form didn't do anything so here's the code class RegisterForm(forms.ModelForm): email = forms.EmailField(label="E-Mail", error_messages={'required': 'Please enter your name'}) class Meta: model = LowUser fields =['fullname', 'email', 'password', 'bio'] widgets = { 'password' : forms.PasswordInput() } def clean_fullname(self): data = self.cleaned_data.get("fullname") if 'ab' in data: raise forms.ValidationError('invalid') else: return data if i input "ac" to the fullname it works perfectly fine it adds the input to the database. But if i input "ab" it didn't do anything it doesn't give me any errors nor add the input to my database. And I'm pretty sure my forms.ValidationError is bugging because if i change my raise forms.ValidationError('invalid') to raise NameError('Test') like this def clean_fullname(self): data = self.cleaned_data.get("fullname") if 'ab' in data: raise NameError('Test') else: return data and i input "ab". It works completely fine and it gave me this page and I'm using django 2.1.5 if you're wondering i would appreciate any help thank you in advance
