form rendering 'None' in production
When I use the password reset in development it works fine. However in production after the user opens the reset email the password reset form is not displayed however other forms on the site via crispy forms are working fine. Nothing has been changed from dev to production besides the url in the view. The server and dev are running the same version of crispy forms. I did it based off this tutorial and it seems I have made all the required changes for production When checking the urls of the email between production and dev i do not see an issue http://127.0.0.1:8000/reset/MQ/***hm*-e00d**b30b635b358be1573e********/ https://domain.co/reset/MQ/***ht*-71ff80c**580c6cecc3ffd44********/ If I try and render the form like {{ form }} it only renders None leading me to believe the context is not being passed view: def password_reset_request(request): if request.method == "POST": password_reset_form = PasswordResetForm(request.POST) if password_reset_form.is_valid(): data = password_reset_form.cleaned_data['email'] associated_users = User.objects.filter(Q(email=data)|Q(username=data)) if associated_users.exists(): for user in associated_users: subject = "Password Reset Requested" plaintext = template.loader.get_template('users/password_reset_email.txt') htmltemp = template.loader.get_template('users/password_reset_email.html') c = { "email":user.email, 'domain':'domain.com', 'site_name': 'Website', "uid": urlsafe_base64_encode(force_bytes(user.pk)), "user": user, 'token': default_token_generator.make_token(user), 'protocol': 'https', } text_content = plaintext.render(c) html_content = htmltemp.render(c) try: msg = EmailMultiAlternatives(subject, text_content, 'myemail@email.com', [user.email], headers = {'Reply-To': 'myemail@email.com'}) msg.attach_alternative(html_content, "text/html") msg.send() … -

Calling view via ajax with submit button works, but hitting enter key just displays ajax dictionary
I have a todo list app adds a Task object to the database and appends it to the page, it is working without a problem. However, it only works when I click the submit button, if I hit the enter key, I just see the ajax data in my browser as such: {"task": {"id": 1, "title": "example task", "completed": false}} and I am curious as to why this is and if there is a way to change this functionality? The tutorial I'm following mentioned that on my form I must use <button type="button"> and not <input type = "submit"> because the ladder will "send the forms data directly to the TaskList view, but we want to use another way of sending requests so we need to disable this behavior." I imagine that is what is happening when I hit the enter key? Code: html: <form id = "createTaskForm" method="post" data-url = "{% url 'task_list_url' %}"> {% csrf_token %} {% for field in form %} {{ field }} {% endfor %} <button id = "createButton" type="button">Sumbit</button> </form> <div id = "taskList"> {% for task in tasks %} {{task.title}} {% endfor %} </div> JavaScript/jQuery: $(document).ready(function(){ $('#createButton').click(function() { // Get form data let … -

Problem with filtering data via custom function in Python (Django)
I want to get 4 random objects from Product I'm trying to filter it by check_existing_id function and random.randint and I use while loop to get 4 objects from the database.

Performing a Subquery, Sum and Join in django ORM

Exiftools not installing on Heroku
I am trying to deploy my first project on Heroku and having an issue trying to install Exiftools on Heroku. My site is highly dependent on using ExifField within my models to get image information from pictures which is then displayed within my Django Admin to be edited etc. This all works fine locally in development. Exiffield relies on Exiftool.exe to work, so I have to install a buildpack to Heroku which I have done, but it fails to see it during release when pushing to Heroku via CLI. All Django modules have installed OK. I have added Procfile , requirements, runtime and everything seems to go OK, it even states it's intalled Exiftool but fails on release. Log below.

Edit FileField file contents from Django Admin
I have a situation where I have python scripts that are stored as files that need to be modified from the Admin panel. Currently some of my models can have scripts attached to them: class Action(PolymorphicModel): title = models.CharField(max_length=100) text = BBCodeField('text', blank=True) action_script = models.FileField(upload_to='action_scripts') In my Admin panel I can upload a file but I have been asked to make this file editable in-place if the user has the right permissions. I've searched all over for an idiomatic way to do this, and so far I've come up with the following ideas: Override the FileField widget to include an text edit box and save button. This seems very brute forced Replace models.FileField with subclass of models.TextField, implement read from file, save to file, but then I lose the upload widget and data still gets stored in DB. This seems dirty because in the database all I'm storing is a filename. FileField feels like the right field type here. Write a custom ModelForm that includes forms.TextField. Handle save to file using the save method. I'm not sure how to accomplish this because I would have to generate a filename on the fly and I don't have a primary key … -
Handle deadlock in django with corrupted savepoint
I have an unavoidable bulk_create deadlock in my code. I decided to handle this part inside an atomic block and re-issue transaction when deadlock happened. Something like this: while True: try: with transaction.atomic(): bulk_create_some_data() return except OperationalError: log_error() continue But this causes error You can't execute queries until the end of the 'atomic' block. I checked history of statements of mysql and found that the savepoint has been corrupted as below log shows. *************************** 1. row *************************** event_id: 1 SQL_TEXT: set autocommit=0 MESSAGE_TEXT: NULL *************************** 2. row *************************** event_id: 2 SQL_TEXT: SAVEPOINT `s139836523404544_x2` MESSAGE_TEXT: NULL *************************** 3. row *************************** event_id: 3 SQL_TEXT: INSERT INTO `Transaction` ...

How to prefill serializer with user and fixed data?
I'm creating a simple game in which, after you log in, you need to create a character. My first problem is that I don´t know how to map the character I want to create to the User field (that has a OneToOne relationship). I'm using Simple DRF simple JWT for registration/login (which returns, after login, just the token and the refresh token) I wanted to prefill some fields (like hp set to 100, lvl to 1, etc). My approach is the following but it's not working, always getting something like "lvl": [ "field is required."] : Serializer: class CreateCharacterSerializer(serializers.ModelSerializer): hp = serializers.IntegerField(required=True) lvl = serializers.IntegerField(required=True) class Meta: model = Character fields = ('user', 'name', 'lvl', 'hp', 'current_hp', 'strength', 'agility',) def create(self, validated_data): instance = self.Meta.model(**validated_data) validated_data["lvl"] = 1 instance.save() return instance Views: class CharacterCreate(generics.CreateAPIView, PostUserWritePermission): permission_classes = [PostUserWritePermission] queryset = Character.objects.all() serializer_class = CharacterSerializer def post(self, request, format='json'): serializer = CreateCharacterSerializer(data=request.data) if serializer.is_valid(): character = serializer.save() if character: json = serializer.data return Response(json, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
