Value too long for type character varying(3) Django Models
I can't seem to find out what is happening, the values for paymenttype are 3 characters long, so if anybody could tell me whats the problem with this model I'd be grateful. class PaymentType(models.Model): INSCRIPTION = 'INS' CROSSSFIT = 'CRF' FUNCTIONAL = 'FUN' KICKBOXING = 'KBX' ALL_ACCESS = 'ALL' UNSPECIFIED = 'UNS' PAYMENT_CHOICES = ( (INSCRIPTION, 'Inscription'), (CROSSSFIT, 'Crossfit'), (FUNCTIONAL, 'Functional'), (KICKBOXING, 'Kickboxing'), (ALL_ACCESS, 'All access'), (UNSPECIFIED, 'Unspecified'), ) payment_code = models.CharField(max_length=3, choices=PAYMENT_CHOICES, default=UNSPECIFIED) amount = models.FloatField() class Payment(models.Model): payment_type = models.ForeignKey(PaymentType, on_delete=models.SET("UNS")) date = models.DateField(default=timezone.now) reference = models.IntegerField() athlete = models.ForeignKey(User, on_delete=models.CASCADE) def __str__(self): return self.payment_type def get_absolute_url(self): return reverse('payment-detail', kwargs={'pk': self.pk}) -
Saving images names into the database - Django
I have the folllowing class model in my Django website: class Buy(models.Model): category = models.ForeignKey(Category, related_name='sell', on_delete=models.CASCADE) title = models.CharField(max_length=100) image = models.FileField() image2 = models.FileField(blank=True) description = models.CharField(max_length=300) date = models.DateField(default=timezone.now) buy_price = models.DecimalField(max_digits=6, decimal_places=2) sell_price = models.DecimalField(max_digits=6, decimal_places=2) seller = models.ForeignKey(Seller, on_delete=models.PROTECT) showcase = models.BooleanField(default=False) As you can see, I store photos files with 2 fields: image and image2. But now my client requested me to add more photos. My doubt is: Should I continue adding new fields to this class, for example, image3, image4, image5 and so on? The problem I see: not every records will have so many photos and the most of them will become "empty". Should I only upload the new photos without saving their names into the database? In this way, the new photos should follow some name related to the image class field. I mean, unique_photo_1.jpg goes inside the image field, unique_photo_2.jpg is not saved into the database but is related to this field, as well as the unique_photo_3.jpg. What is the best practice? Thank you! -
Django - The label doesn't change its name

NuxtJs asyncData get data based on $route
I've been using NuxtJs for a short time and I'm learning how to use the asyncData method. In my project I would like to load data according to the url. Show my code : async asyncData({ $axios, params }) { try { newFolder = false let folder = {} if (params === '/new/folder') { newFolder = true } else { folder = await $axios.$get(`/folder/${params.id}/`) } return { folder, newFolder, } } catch (e) { return { folder: {}, newFolder: false, } } }, As you can see I would like folder to be an empty object if the url is === /new/folder, on the other hand, I would like in other cases to recover the data on my api. But with this code, whatever the url, axios tries to get the api. -

Django admin list_filter lookup options - ordering issue
I have recently updated an old project from Django 1.11 to 2.2 LTS. I have noticed that the list_filter filters for foreign keys do not longer have an alphabetical order for their lookup names (as it used to). If I create a custom filter, the ordering of the results is correct. list_filter = ( 'modela__modelb' ) What am I missing? -
How can I keep defined data out of the field in django rest framework?
I'm trying to mark the number of comments on some post on the api. First of all, by defining the commentserializer, received the comments after, it declared comments in the defined later, its commentserializer there counting the number of comment_cnt. By the way, if you do this, the comments will be in the fields. Is there a way to remove comments from fields or is there a better way to display the number of comments? Here is my codes.

Accessing "request" object within Jinja2 "environment" function

Render variables in DB strings?
I'm building a survey tool. The questions will be derived from templates. But of course, it would be nice if they would contain personalized elements, too. Here is an example: How many products from {{ brand_name }} do you buy per week? This information should not be rendered in a HTML template but rather sent via JSON. Django comes with functions like render_to_string that take a context object and a template path. But I'm not sure if they can be used here. I'm super happy for any help! Thanks! -

If and else statements in Django template
