Django docker logging
I am running docker on my Mac. I am having an issue with my views.py and I am trying to print out to the Mac docker desktop some messages to try to debug my code. I have followed Django and docker: outputting information to console and it doesn't seem to work for me. The only thing that gets printed out to the docker desktop logs is just errors when they occur, Normally all I get is just the 200 ok from the http request. I have used the print statement and the info statement and neither of them print out. ------------------------------------ setttings.py ------------------------------------ from pathlib import Path import os import logging.config import json # SECURITY WARNING: don't run with debug turned on in production!

using primarykeyrelated for post and string for get call in django rest framework
I have a model in which some fields are a foreign key to another model. Hence while creating the object of that model I have to use primary key but while calling get api I need to show those fields as stringrelated field. How to achieve that?? My model: class Example(models.Model): tour = models.ForeignKey( Package, on_delete=models.CASCADE, null=True, related_name="example" ) site = models.ForeignKey( Destination, on_delete=models.CASCADE, null= True, related_name= "example", ) location = models.CharField(blank=True) /...........other fields........../ My serializer: class ExampleSerializer(serializers.ModelSerializer): # tour = serializers.StringRelatedField() # site = serializers.StringRelatedField() class Meta: model = OnlineClass fields = ['id','tour','site','other fields.....'] def to_representation(self, instance): data = super(ExampleSerializer, self).to_representation(instance) return data Here while creating the example object, I need to pass tour and site as ids but while calling list method I need to show both fields as string related fields. As I define them as stringrelated field as above (later commented out) , I can create the object but those fields will be set as null. I don't want to make another serializer. How to achieve this?? -

How can I check if a boolean from a different model is true for a user of a team?
I have the following model I want to use to add rights to users that are part of a team: class Rights(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) team = models.ForeignKey(Teams, on_delete=models.CASCADE) read = models.BooleanField(default=True) write = models.BooleanField(default=False) edit = models.BooleanField(default=False) Some Users need to be able to make new entries.

How to access auth_user_group table by ID
How can I directly specify the ID column of auth_user_group table in queries/DML? I am referring to auth_user_group.id, not auth_group.id nor auth_user_group.group_id. For example, I want to directly issue DML like: delete from auth_user_group where auth_user_group.id = 1 select id, user_id, group_id from auth_user_group where auth_user_group.id = 1; I am not interested in the following workaround which avoids auth_user_group by requiring knowledge of the group name, instead of the auth_user_group.id, and results in two queries instead of 1: group = Groups.get(name='foo') user.groups.remove(group) If you wanted to directly query a junction/M:N table in Django, normally you would create a "through Model" and can then query it directly. However in this case, the django.contrib.auth.models definition do not use a through model. -

Apply widget dynamically depending on field value
In a Django project, I have a form with a use_format checkbox (unchecked by default) and a post CharField. Because I want to be able to add extra features to the post text field, like text formatting, I have imported a RichTextEditor widget to do so. The thing here is that I only want to use the RichTextEditor widget in post if use_format is checked. class ArticleForm(ModelForm): def __init__(self, *args, **kwargs): super(ArticleForm, self).__init__(*args, **kwargs) if not self.instance.use_format: self.fields['post'] = forms.CharField(widget=forms.Textarea) class Meta: model = Article fields = '__all__' widgets = { 'post': RichTextEditor(options={...}), } So far, what I've been doing when I want to create an article with formatting is to create the article with use_format checked. Save. Then edit the article and there I have the post with the RichTextEditor. I would like to have the post changing automatically between CharField or RichTextEditor as I check or uncheck the use_format checkbox. First, is this possible? What I've been trying: I've added a custom script on my ModelAdmin to detect changes to the use_format value class ArticleAdmin(admin.ModelAdmin): form = ArticleForm class Media: js = ('js/toggleUseFormat.js') toggleUseFormat.js: if (!$) { $ = django.jQuery; } $(document).ready(function () { $("#id_use_format").change(function () { // … -

Django No Reverse Match Error - Nothing is working

What Is Can Order In Django Formsets Actually For?
I've spent a fair amount of time the last day or so exploring the can order field with Django Formsets but I can't for the life of me actually figure out what it's for. Apparently it doesn't update the database...and it does put an order number field with the form....but beyond that what is it for? I can't find any useful documentation on how to actually use this field. Do I have to write Javascript in order to get this field to do anything actually meaningful? I get the delete option...and you have to add code in to delete the record...So I guess I'm to take it the same is required for the can_order field? Sorry if this is a silly question but I've spent more time trying to figure this out than what would be reasonable by now. -
CSP error for bootstrap image in navbar hamburger
I just added content security policy to my Django site. I have everything working correctly except these two errors for images that I had no idea what they were I spent a bunch of time trying to figure it out until I noticed that the icon on the bootstrap hamburger menu was gone In the CSS I found this telling me that this must be the image in the navbar causing this error. I found a few workarounds online but they presented security vulnerabilities and i would like to do it properly How can I go about solving this issue.

Django AttributeError object has no attribute 'upper'
I am implementing an API for an image labelling app. I have customised a create() method for Tagging. A Tagging contains a tag, which is an object containing a name and a language. To make tags easier to compare to each other, I have to save all tags either in upper or lower case. serializers.py def create(self, validated_data): """Create and return a new tagging""" user = None request = self.context.get("request") if request and hasattr(request, "user"): user = request.user score = 0 tag_data = validated_data.pop('tag', None) if tag_data: tag = Tag.objects.get_or_create(**tag_data)[0] validated_data['tag'] = tag tagging = Tagging( user=user, gameround=validated_data.get("gameround"), resource=validated_data.get("resource"), tag=validated_data.get("tag"), created=datetime.now(), score=score, origin="" ) tagging.save() return tagging I have tried both this tag=validated_data.get("tag").upper() and this: tag=validated_data.get("tag").lower() and I get an AttributeError 'Tag' object has no attribute 'upper' or 'Tag' object has no attribute 'lower'. I want for this tag: { "gameround_id": 65, "resource_id": 11601, "tag": { "name": "TagToTestNow", "language": "de" } } to be saved something like "TAGTOTESTNOW" or "tagtotestnow" to make Tag comparison easier. How can I achieve this? -
Recursive function to calculate the children of a parent
I have a set of data that looks like this: Person1 is the parent of Person2 Person2 is the parent of Person3 and Person4 Person3 is the parent of Person1 If I try to calculate the whole tree for Person1, the max recurssion will be exceeded and the program will terminate in an error. The expected result would be Person1 -> [Person2, Person3, Person4], so basically in the case the the calculation has to be repeated for an element that is already in the list, this has to be ignored. Do you have an idea, how could I solve this problem? My function looks something like this: def compute_children(self): children = [] children.extend(self.child) for child in children: temp = child.compute_children() if 0 < len(temp): children.extend(temp) return children -

JsonPickle decodes a function into None value
I am using jsonpickle in a django project to store lists, sets or dicts of custom objects in a models.JSONField. I'm running tests to check my code: everything is fine, but goes wrong if I just try to .reload_from_db() an instance containing this kind of JSONField in it. The problem comes from json decoding. After digging this, I found that this string: { "py/set": [ { "py/function": "Main.files.Effects.AddEffectToAttacks.apply.<locals>.remove_effect.<locals>.wrapper" } ] } becomes: {None} let's say: s = '{\n "py/set": [\n {\n "py/function": "Main.files.Effects.AddEffectToAttacks.apply.<locals>.remove_effect.<locals>.wrapper"\n }\n ]\n}' jsonpickle.decode(s) will return {None} when it is obviously not None but a function: Main.files.Effects.AddEffectToAttacks.apply.<locals>.remove_effect.<locals>.wrapper Does someone have an explanation and a solution for this please?
