ALTER COLUMN "active" TYPE boolean USING "active"::boolean
I am currently working through "Django 3 By Example" by Antonio Mele. Chapter 3 has me working through creating a blog application. In the chapter it has me change my database from MySQL to PostgreSQL and then migrate the data. When I migrate the data I get this error: **django.db.utils.ProgrammingError: cannot cast type timestamp with time zone to boolean LINE 1: ..." ALTER COLUMN "active" TYPE boolean USING "active"::boolean** I have gone through some PostgreSQL documentation and back through my code but I am unable to complete the migrate due to this error. I have been stuck at this same place for quite some time and can not seem to isolate the correction for the error. Any help is appreciated. -
Django, problem with the comment form below the post
I just can't figure it out for a very long time, I made a conclusion of comments to posts from the admin panel. But I just can't figure out how to make a comment form right under the post for users to comment.

How to send large post request in flutter
I'm trying to upload my users' contacts to my server (running django-rest-framework) from flutter, but am having a hard time due to the size of the request. The contacts are sent from a screen within a bottom navigation bar, so I would like to request to continue even when the user switches pages (we're using bloc and flutter clean architecture to organize logic). I looked into https://pub.dev/packages/flutter_uploader and multipart uploads but it seems that most are geared towards files rather than json in the post body. The size of the contacts request is partly due to the included avatar images, encoded in base64. I have them as base64 encoded strings because that is easier to parse and deserialize on the server, and I'm not sure how to parse files in django-rest-framework ModelSerializers. Is there any way to upload a large json (List<Map<String, dynamic>>) request to my server so that: The request continues even when the bloc that called the usecase->repository->remotedatasource.dart is recycled when user selects different window in bottom navigation bar. The request contains the images in a way I can process without too much django-rest-framework code and allows me to automatically save the images to s3 as happens automatically … -

Filter ForeignKey choices in an Admin Form based on selections in same models ManytoMany Field?
I am making a "matches" model that currently has these fields in them: event = models.ForeignKey(Event, on_delete=models.RESTRICT) match_participants = models.ManyToManyField(Wrestler, on_delete=models.RESTRICT, null=True, blank=True,) match_type = models.CharField(max_length=25, choices=match_choices, default=BLOCK) match_result = models.CharField(max_length=25, choices=result_choices, default=NOT_OC) winner = models.ForeignKey(Wrestler, on_delete=models.RESTRICT, null=True, blank=True, related_name="winner") In my scenario the "winner" can only be one of the foreignkeys chosen in "match_participants", I would really like to filter the winner field to only those chosen foreignkeys. Is this possible? I know you can filter foreign key selections based on entries into other models, but not too sure about same table entry. Here's a UML example of what my database structure currently is: -
Django - Why is my form invalid when a non-required field is not filled?
My form triggers form_invalid when the field "category" is empty. The weird thing is, when the view displays, the "description" field does not have the asterisk indicating it's required, unlike "name" or "enabled", for instance. Also, when I try to send the form with an empty name, it correctly displays a little yellow mark and says "This field is required", but it doesn't say that when the category is empty. So, it seems to correctly recognize that the category is not required, it just says it's invalid after I send the form. My form looks like this: class ProductForm(forms.Form): name = forms.CharField(max_length=80, required=True) category = forms.ModelChoiceField(queryset=None, required=False, label='Categoría') description = forms.CharField(max_length=150, required=False) price = forms.FloatField(required=True) image = forms.ImageField(allow_empty_file=True, required=False) extras = forms.FileField(allow_empty_file=True, required=False) enabled = forms.BooleanField(required=False, initial=True) def __init__(self, user, *args, **kwargs): self.user = user super(ProductForm, self).__init__(*args, **kwargs) self.fields['name'].label = 'Nombre' self.fields['description'].label = 'Descripción' self.fields['price'].label = 'Precio' self.fields['image'].label = 'Imagen' self.fields['extras'].label = 'Extras' categories = Category.objects.filter(store=Profile.objects.get(user=user).store) if categories.count() == 0: self.fields['category'].required = False self.fields['category'].queryset = categories self.fields['enabled'].label = 'Habilitado' It is included to my view in this way: class ProductCreateView(LoginRequiredMixin, CreateView): template_name = 'products/product_form.html' model = Product fields = ["name", "category", "description", "price", "image", "enabled", "extra"] success_url = reverse_lazy("orders:products") And … -

django Pycharm 2020.2.2 not resolving static files when using "pathlib.Path" to address BASE_DIR
I'm using the latest version of Pycharm, 2020.2.2 and django 3.1. In my project, I removed the default settings.py and created a directory named settings, so the whole project root looks like: tsetmc ├── asgi.py ├── celery.py ├── context_processors.py ├── __init__.py ├── settings │ ├── base.py │ ├── __init__.py │ ├── local.py ├── urls.py ├── views.py └── wsgi.py and in the base.py, I defined the static files setting as: from pathlib import Path BASE_DIR = Path(__file__).resolve().parent.parent.parent ... STATIC_URL = '/static/' STATICFILES_DIRS = [ BASE_DIR / 'assets/' ] STATIC_ROOT = BASE_DIR / 'staticfiles/' MEDIA_URL = '/media/' MEDIA_ROOT = BASE_DIR / 'media/' Everything works fine in the browser and the static files are successfully loaded using the {% static %} tag; However, Pycharm can not resolve any of the static files in the templates. I enabled Django Support, set Django project root and settings in the Pycharm settings accordingly and also set the Template Language as Django; but it didn't solve the issue. After some trial-and-error, I found an odd solution; If I use import os and os.path.join() to locate the static paths, instead of from pathlib import Path and /, Pycharm can resolve the static files without any problem. So when … -
How to show files after clicking on certain category on html/django?
I have an html file that outputs a multilevel list. I'm able already able to get the id of that list with an onClick. What I want to do is that once I've clicked on the list element, a table appears with the files from that category. I don't mind if it reloads the page, but it would be better if it's not needed to. This is what my list looks like: <body> <nav id="navigation"> <ul class="parent"> <li class="big-section">Commissions <ul class="child"> <li class="area" id="Pays">Pays</li> <li class="area" id="Quotas">Quotas</li> </ul> </li> <li class="big-section">Store Rank <ul class="child"> <li class="area" id="Store Rank">Store Rank</li> </ul> </li> <li class="big-section">Ranker <ul class="child"> <li class="area" id="Ranker">Ranker</li> </ul> </li> </ul> </div> </body> This is what my table looks like: <table class="documentTable"> <thead> <tr class="headers"> <th>Document</th> <th>Upload Date</th> <th>Summary</th> </tr> <tbody> {% for f in upload %} <tr class="data"> <td> <a href="{{f.file.url}}" download="{{f.file.url}}">{{ f.title }}</a> </td> <td>{{ f.department }}</td> <td> {{ f.date }}</th> <td> {{ f.summary }}</th> </tr> {% endfor %} </tbody> </thead> </table> This is the javascript I'm using to animate the table and get the id of the clicked list item <script> $("li.area").click(function () { console.log($(this).attr('id')); // jQuery's .attr() method, same but more verbose }); $(function () { … -

How to obtain content_type from a Django Model Class?
I am trying to obtain the ContentType for a django models.Model. Not trying to get the model from a ContentType, which is all I can find in the docs. For example: model_name = 'FooBar' MyModel = apps.get_model('app_xyz', model_name) MyModel <class 'apps.app_xyz.models.FooBar'> How do I get the ContentType of MyModel? The only thing I can figure out to do is set the model_name string to lower and directly query ContentTypes: ct = ContentType.objects.get(model=model_name.lower()) That seems really fragile, and using lower() has a code smell I don't like. I've looked through FooBar's methods, _methods, and __methods to no avail. Thanks! -

search field in Django returning blank page?
I'm doing an encyclopedia project with different entries linked on the homepage. I'm also trying to add a search bar to the homepage so if someone searches up an entry that has already been created then they are taken directly to that entry page.

How to get the difference of two values of same column in django

From that table, I need to find the difference between yesterday's value and today's value of an attribute C of all the users and return the IDs of the users' for which the difference is greater than 10. Can this whole thing be done in one or two queries? The solutions I have in my mind are naive and will need separate queries for each user. -

Passing static path to included template
Is it possible to pass a static path as a variable to an included template? I need to repeatedly include a template on my page but its always with different logos.
