Cannot apply makemigrations to model after modifying
I implemented a model for my Django app in models.py. Everything worked fine. Then I tried adding a new property to the class. If I now run "makemigrations" I get the error "table movieapp_movie_class has no column named show_movie". I thought that running makemigrations was the command to add this column to the table. I've tried deleting db.sqlite3 and the migration-folder in the app-folder which did not work. from django.db import models # Create your models here. class movie_class(models.Model): show_movie = models.CharField(max_length=100) # this is the new property I wanted to add movie_id = models.CharField(max_length=100) title = models.CharField(max_length=100) rating = models.CharField(max_length=100) poster = models.CharField(max_length=100) -
Django Rest Framework - issue with DELETE - CSRF not found
I'm using Django Rest Framework with CSRF. POST and PUT methods work as expected, but DELETE is giving error 403 with - following message "{"detail":"CSRF Failed: CSRF token missing or incorrect."}. It appears that frontend application (Angular) is doing a proper POST and PUT requests. I'm not getting any issues with CSRF nor CORS.

Django: How to follow ForeignKey in unique_together constraint?
I have three Django Models: a Property Model, most importantly having a slug field; a Collection Model; and a PropertyCollectionRelationship Model. The last model models a ManyToMany relationship between the other two and is used as an explicit through of a ManyToManyField. from django.db import models class Property(models.Model): slug = models.SlugField() collections = models.ManyToManyField('Collection', blank=True, through='PropertyCollectionRelationship') # ... other unimportant stuff omitted ... class Collection(models.Model): pass # ... lots of stuff omitted ... class PropertyCollectionRelationship(models.Model): prop = models.ForeignKey(Property, on_delete=models.CASCADE) coll = models.ForeignKey(Collection, on_delete=models.CASCADE) I would like to add a uniqueness constraint which ensures that each collection has at most one property with any given slug. I tried to express this via a unique_together option in the Model Meta: class PropertyCollectionRelationship(models.Model): class Meta: unique_together = [['coll', 'prop__slug']] prop = models.ForeignKey(Property, on_delete=models.CASCADE) coll = models.ForeignKey(Collection, on_delete=models.CASCADE) This resulted in the following System Check Error: SystemCheckError: System check identified some issues: ERRORS: myapp.PropertyCollectionRelationship: (models.E012) 'unique_together' refers to the nonexistent field 'prop__slug'. How, if at all, can I achieve such a constraint? -
How do I query the database for all the points that are within a certain radius from a users location?
I am trying to get all the points from the database that are with a certain radius from the users location(e.g 10km). So basically I would like the user to input a location, which would then be converted to lat and lng using the google maps api and have the application search for and return all the stores in the database that are within a 10 km radius of the users location. I have tried Haversines formula but can't seem to get that to work since I do not have a strong understanding of how to filter search results from the database. Could anyone please explain to me how best to query the database for results within a 10km radius using Haversines formula? models.py: class Detail(models.Model): name = models.CharField(max_length=30, blank=True) location = models.CharField(max_length=300, blank=True) lat = models.

How to display image from temp folder to template in Django
I have just started working on django(But I have worked on python for about a year). For my MFA application, I have created .png file(qr code) in my admin.py file and I have stored this png in /tmp/ dir. Now I need to show this image to template. The reason I have stored this file in temp dir becouse the image created is one time. SO I want to show this image view for once and delete after that. So anyone can help me to get me out from this? Thanks for advance qr_url = "otpauth://totp/%s:%s?secret=%s&issuer=%s" % (label, user, secret, label) url = pyqrcode.create(qr_url) random_file_path = datetime.datetime.now().strftime("%Y%m%d%H%M%S") url.png('/tmp/'+str(random_file_path)+'.png', scale=4)` This is how I created png I have tried by directly providing temp dir path.

Use of `get` for a `select_for_update` query in order to reduce the number of rows getting locked
I would like to know if there is a good solution for this scenario. When a select_for_update is used in a query set, all matching results are locked until the particular block of code has not finished execution. This has become a little critical as simultaneous requests which could be served are being returned back by DatabaseErrors. Below is a sample query for which select_for_update has been implemented qs = Coupons.objects.select_for_update().filter(brand=brand).values('coupon').order_by('id') return qs[0] If we have 1000 coupons for a particular brand, then the entire 1000 rows are locked. I am unable to use get since we are returning the coupons on a FIFO basis and we would need to return coupons which were added first Is there any way I could use get, or minimize the number of rows being locked -

How to save MultipleChoiceField to db
I want to create a settings page where a user can select multiple values of skills they have. It will have a main category and then subcategories. I need to save those into my database, so I can query them and show their selected skillset again. I know how to create the MultipleChoiceField but not how to save them to the database. How would I go on about that? Forms.py from django import forms class skills(forms.Form): jobs = [ ('Håndværker', ( ('Gulv', 'Gulv'), ('Væg', 'Væg'), ) ), ('Murer', ( ('Mur', 'Mur'), ('blabla', 'blabla'), ) ), ] job = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple, choices=jobs) Views.py from .forms import skills def index(request): if request.method == 'POST': form = skills(request.POST) if form.is_valid(): picked = form.cleaned_data.get('job') # do something with your results else: form = skills return render(request, 'settings/index.html', {"form":form}) It currently looks like this when the page loads which is good. Next step is just how I would save it to the database, so I can display this again with their previous chosen values. -

How to save a model-instance using serializers in django?
I would like to save a class instance in my database using serializers, provided by DRF. Serializer: class PersonSerializer(serializers.ModelSerializer): class Meta: model = Person fields = '__all__' here I try to save an instance: p = Person(Name = "Test") _srlz = PersonSerializer(data = p) The real case is little bit more complicated, but sanse the same. Unfortunately the data - _srlz.data is empty. So if I try to save data via _srlz.save() method then nothing change. Otherwise if I request an existed object p = Person.objects.filter(id = 1) _srlz = PersonSerializer(data = p) Then my _srlz.data will not be empty. How should I save this object if datasource is not JSON-object, but model-class instance?Should I first serialize it and then deserialize again? I already tried to save instance calling a .save() method, provided by model's default Manager, but I would like to separate my model and service methods so all database operations performed by serializers. Or is it OK in this case, because I deal not with pure JSON, but with model instance? But how can I then validate data? -
