Recommended database administrator for Django and PostgreSQl
Having a web based in Django with PostgreSQL : django.db.backends.postgresql_psycopg2 I used to work in other framework with database administrators, such as PhPmyAdmin, SequelPro for MySQL DBs. I liked to see all rows, run some queries... Now, the django admin allows me to see some info, but I would like to run some queries and get some KPIS. Is there a similar database manager for postgreSQL? Is possible to install that or should use Django admin? Web info: Django 2.1.7 DB: django.db.backends.postgresql_psycopg2 Hosted in a Docker container with Ubuntu 20.04 -

django smart-select security issue
I have implemented django smart-select successfully, but it has problem with security. The endpoint is readable without any permissions. I also found a warning from smart-select document but I don't know how to use django-autocomplete-light. Does django-autocomplete-light support the same feature with smart-select? Is there anybody know how to fix this security issue. Warning: The AJAX endpoint enforces no permissions by default. This means that any model with a chained field will be world readable. If you would like more control over this permission, the django-autocomplete-light package is a great, high-quality package that enables the same functionality with permission checks. -

Django3 prefetch_related
I had worked by django 2.X. But i'm gonna use django3.x at my new project. At version2, when I should make outer join.. I used prefetch_related and filtered about model of prefetch_related.

How to reduce option from one ForeignKey when there are two different ForeignKey and unique_together is defined?
I have two three models Product, ClothColor and Color. # products/models.py class Product(models.Model): ... class Color(models.Model): ... class ClothColor(models.Model): product = models.ForeignKey(Product, on_delete=models.CASCADE) color = models.ForeignKey(Color, on_delete=models.CASCADE) ... class Meta: unique_together = ('product', 'color',) I wanted to allow only one combination of product and color in ClothColor, so I have used unique_together in Meta class. This constraint work fine. Now, I am using TabularInline to display ClothColor in admin panel, so it would be easier to add a product as well as its colour variations. # products/admin.py class ClothColorInline(admin.TabularInline): model = ClothColor ... class ProductAdmin(admin.ModelAdmin): ... inlines = (ClothColorInline,) And, this is how my admin panel looks. Now, when I add new color to the color field in clothColor, it also displays already used color. img: drop down menu in admin panel. Due to the unique_together constraint it shows me error, thus, it prevents accidently fill same color twice, but I need a way to hide the option altogether if the color is already used. So, how can I reduce the option in color field when I have already used that color? -
How to apply condition in filtering from Mysql using list of values
Db table verystrong strong moderate weak veryweak US aa a ba b caa UK aa a baa b caa Austria a baa ba caa ca Belgium a baa ba caa ca Japan aa a baa b caa UAE ba b b b1 c country='UK' traderow=exporttable.objects.filter(ratio=country).values()[0] traderow output: {'id': 2, 'ratio': 'UK', 'verystrong': 'aa', 'strong': 'a', 'moderate': 'baa', 'weak': 'b', 'veryweak': 'caa'} next i have the list a a=['verystrong','verystrong','strong','strong','strong','strong','strong'] a is rating made for years from 2013 to 2019 e.g 2019 rating is strong , in 2013 is strong. Now i want for each value in the list to match with value in traderow to find trade rating: I can return only one value from the list at a time: value1=a[0] whihc is 'verystrong' (year 2013) value7=a[6] whihc is 'strong' (year 2019) trade_rating2013=traderow[value1] which returns for year 2013 aa trade_rating2019=traderow[value7] which returns for year 2013 a My question is how to implement this operation effectively for the whole list not implemneting for each list seperately ?is that possible to apply lambda ? I am still learning python and would appreciate your help to optimize the code to remove redundancy and make it more effecient. -
Image Kit and ImportError: cannot import name 'six' from 'django.utils'
I'm trying to upgrade to Django 3, and I keep getting errors with 'six' being dropped from django.utils.

CreateView not uploading image and name of the user for a post
I'm making a web app which allows users to register to the site and let them post their posts. For taking in their post I have used the built in CBV: CreateView. In the user post I take in the name of the user using foreignkey with null=True, image, title. The problem is: when I go to the detail page of that post it shows that there is no file associated with the image field, so I made an if statement to check if the post contains an image. But then too, it does not show the image. It shows User:None. I don't know what is happening, I have read that CBV take the self.request automatically and there is no need to link the current user to the post. Following are the screenshots of my code: models.py browser image before clicking submit button browser image after clicking submit button (detail page of the post) post_detail.html views.py -
Objects with several ManyToManyField relation are duplicated in the result page of Django Admin
I have a ManyToManyField relation between two models and I can add a new relation with the code bellow, but then in the admin section of Django the same object (same id) is listed twice. Is it normal that an object with several ManyToManyField relations is duplicated in the result page of the Django Admin and how could I display only unique objects? My models class Exchange(models.Model): name = models.CharField(max_length=12, blank=True, null=True) class Currency(models.Model): code = models.CharField(max_length=100, null=True) exchange = models.ManyToManyField(Exchange, related_name='currency') This is how I update the m2m ex = exchange # This is my Exchange object code = 'ABC' try: Currency.objects.get(code=code, exchange=ex) # here I check a same relation exists except Currency.DoesNotExist: try: curr = Currency.objects.get(code=code) # here I test if the currency object is created with a relation to another exchange curr.save() curr.exchange.add(obj) log.info('New exchange added for currency', code=code, exchange=ex.name) except Currency.DoesNotExist: curr = Currency.objects.create(code=code) curr.save() curr.exchange.add(ex) log.info('New currency added', code=code, exchange=obj.name) else: log.warning('A relation between this currency and exchange is already created') Admin page You can see that Currency objects with id 8, 5 and 3 are duplicated. -
