Using get_model in a custom slug generator raises django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet
I created a custom slug generator function to use in multiple models across multiple apps. To achieve this I pass the relevant django app name and django model as string parameters to the function, so the function can check if the slug is unique for that model: def slug_generator(django_app, django_model, field_name, slug_len, prefix=""): unique_pk = False model = apps.get_model(django_app, django_model) while not unique_pk: random_pks = random.sample( string.ascii_uppercase + string.digits + string.ascii_lowercase, slug_len) new_pk = ''.join(random_pks) search_query = {field_name: new_pk} try: if not model.objects.filter(**search_query).exists(): unique_pk = True except: if not model.objects.all().exists(): unique_pk = True return prefix + new_pk called in models.py like so: class Form(models.Model): form_id = models.CharField( max_length=25, default=slug_generator('forms', 'Form', 'form_id', 25)) The function was working fine when I only was using it for a single model (so i wasn't using get_model, I just hard coded the model it was for). Since adding get_model, this error is thrown on startup django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet. I tried putting the following before my function: import django django.setup() It only led me to a new error RuntimeError: populate() isn't reentrant, so it makes me think that there is a better way to write the function. Is what I am trying to achieve … -

How do I resolve "Invalid service account certificate. Certificate must contain a "type" field set to "service_account"" error to run a Django server?
I'm trying to run a Django server. I have installed python 3.8.2 and the rest of the requirements are installed through a requirements.txt file in the project folder. After installing the requirements, I've tried to run the server but it generates the following error: ValueError('Invalid service account certificate. Certificate must contain a ' ValueError: Invalid service account certificate. Certificate must contain a "type" field set to "service_account".

How to sent data from contact form to my private gmail in django?

Can not create db table in django migration
I have 2 apps "app1", "app2" in my django project. When I ran python3 manage.pymakemigrations, I can see ... Migrations for 'app1': ... Migrations for 'app2': ... But when I ran python3 manage.py migrate, I got error saying django.db.utils.ProgrammingError: relation "auth_user" does not exist "auth_user" is db table for app1.User model. I tried to run migrate separately. It is fine for app2. But when I run python3 manage.py migrate app1, I got No migrations to apply. Your models have changes that are not yet reflected in a migration, and so won't be applied. Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them. I cannot find a solution for my case, anyone can help? -
Gmail API with heroku and django project
I am stuck with identyfing issue on application being deployed to Heroku. It is a python django project that using a Gmail API should send out emails to defined subscribers. Code is as below views.py (where function is called) def MailJournals(new_acts): mailAdresses = models.EmailSubscriber.objects.all().values_list('email') mail_list = [x[0] for x in mailAdresses] journal_date = datetime.strftime(datetime.now(), '%d/%m/%Y') message = MIMEText(render_to_string('newsScrapper/mail.html',{ 'journal_date': journal_date, 'new_acts': new_acts, }), 'html') message['to'] = ",".join(mail_list) message['from'] = EMAIL_HOST_USER message['subject'] = 'Official Journal as of ' + journal_date with smtplib.SMTP_SSL("smtp.gmail.com", 465) as smtp: smtp.login(EMAIL_HOST_USER, EMAIL_HOST_PASSWORD) smtp.send_message(message) settings.py: EMAIL_HOST_USER = env('EMAIL_USERNAME') EMAIL_HOST_PASSWORD = env('EMAIL_PASSWORD') The thing is it perfectly works on localhost so I do not believe this is a code issue.

How to speed up the query transactions for large records in Django, if we are visiting multiple classes to achieve this?
I'm trying to show user profiles suggestion for a loggedIn user based on the tags he/she follows, In my case i have to travel to User_Interests_Tag class to get all the tags, next visit Post_Tag class to get all the posts for each of the tag(loop), once i have the all the postId's, visit the Post class to get each unique user and append it to a profile(List) and used paginator to limit the profiles sent to the client. How can i achieve this without using for loops to increase the overall efficiency and response time from the server? here is the snippet what i want to achieve : #looping through each tag for user_interests_tag in user_interests_tags: #user_post_tags = Post_Tag.objects.in_bulk(user_interests_tags) (used bulk but no luck) user_post_tags.extend(list(Post_Tag.objects.filter(tag_id = user_interests_tag).values_list('post_id', flat=True))) profiles = [] #looping through each tag id for user_post_tag in user_post_tags: #getting the user from post class user = Post.objects.get(id = user_post_tag) #checking if already follows and if already their in user profiles array if user not in profiles and not User_Follow.objects.filter( owner_id = user_id.id, user_id = user.user_id): profiles.append(user) #paginating 6 per request paginator = Paginator(profiles,6) limited_profiles = paginator.page(page) return limited_profiles Any leads very much appreciated, thanks in advance :) -

Why does my Django form not raise Validation Error?
I read through most SO cases regarding this issue but all are kind of specific, so I come here for help. I have impelemented a range filter in my Django project that takes in two inputs set to a low bound and high bound value, and displays the range of data within those bounds. What I'm trying to do, is make it so when a user inputs a higher number in the low bound than the high bound value, a ValidationError is raised for the user to see on the front end, and results are not displayed.

how to make multiple select checkbox with ajax and no button submit
Python 3.9 Django 3.2 I have categories and product , and through a simple form in the template I choose 1 or 2-3 checkboxes and I get the result. How to do it now via ajax and without button 'submit'. I select several product categories and each click on the checkbox is ajax and the next click on the checkbox adds the parameter to the request. it is similar to how you select several parameters in online stores. You have selected 2 parameters and received a filtered list of products I suppose that you need to intercept the sending, store one request in the cache and add a new one to this request <form method="post" id="category-box"> {% csrf_token %} <div class="form-check"> <input class="form-check-input" type="checkbox" name='category' value="{{c.name}}" > <label class="form-check-label" for="{{c.name}}"><a href="{{ c.get_absolute_url }}">{{ c.name }}</a></label> </div> {% endfor %} <button type="submit">Submit</button> </form> -
Will Django always consider an Emoji as 1 character long?

how do I create a javascript function that changes the html when a form submit button is pushed in django
I can easily update the html when it's not part of the form's submit or button. Or even when it's just a pure button element (rather than an input from a form). However, when I try to append a string to the class "chatGoesHere", nothing happens. The consolealso quickly reloads since the form is going to \send. I'm happy to post my views.py and urls.py, however, I'm pretty sure the issue is inside of my html document below: <p class="chatGoesHere" id="chatGoesHere"> 1st Item! </p> <form action="\send\" method="post"> <input type="text" name="userMessage" /> <input type="submit" value="Send to smallest_steps bot" class="sendButt" id="sendButt" /> </form> <script> var btn = document.getElementById("sendButt"); btn.addEventListener("click", updateChat); function createMenuItem(name) { let li = document.createElement('p'); li.textContent = name; return li; } const td = document.getElementById('chatGoesHere'); td.appendChild(createMenuItem("TEST2")) function updateChat(){ const td = document.getElementById('chatGoesHere'); td.appendChild(createMenuItem("TEST3")) } </script> I'd like it so that every time a user pushes the submit button of the form something gets added to the page without the page reloading. Thank you -
Django window.location not replacing string
I have a javascript function in a django view that is supposed to redirect the user to a different URL that contains a query parameter. When I print out the url before assigning it to window.location, it matches the url pattern as expected. However once I assign the URL to window.location, it seems to append the url to the already existing one instead of replacing it, and thus cannot find the matching url pattern.

Proper way to construct classes - Django dartCounter project
I was recently starting to do some programming. I figured out how to use Django a couple of days ago. And now I'm trying to integrate some old Python code with it. I created a simple dartCounter. Which is quite easy in a while-loop. However for the new version I want some graphical interface, so I figured I should make some proper classes to interact with without the usage of while loops for the count mechanism. Those classes should be used in the views.py section in Django. The thing is, I think I already made it overcomplex using this method. First I created a class dart_player() class dart_player(): def __init__(self, name): self.name = name self.score = None self.leg = 0 self.thrown_scores = [] def set_start_score(self, start_score): self.score = start_score self.thrown_scores = [] def update_score(self, score): if self.score != None: self.score = self.score - score self.thrown_scores.append(score) else: print("Error score equals 'None' \n") def reverse_score(self, score): if self.score != None: self.score = self.score + score self.thrown_scores = self.thrown_scores[:-1] else: print("Error score equals 'None' \n") def update_leg(self, leg): self.leg = self.leg + leg Next I ended up creating a class dart_match() and within it, the class leg() since the leg is part of … -
Can you access variable attributes in the django template language with other variables?

Why doesn't the above code work?
