I want the table to be visible only after the submit button clicks. But it's not staying on the screen as it is supposed to be. Once I click the submit button, the table comes up for a second and then again becomes invisible. Please let me know what I am doing wrong in my code. Also please let me know if there is any other way to do it. index.html <form action="#" id="form" method="post"> <div style="margin-left: 2rem;"> <!-- <input class="btn btn-primary" type="submit" value="Submit" id="btn" onclick="hide()"> --> <input class="btn btn-primary" type="button" value="Submit" id="btn" onclick="hide()"> </div> </form> <div style="margin-top: 4rem; display: flex; justify-content: center; align-content: center;"> <table style="display: none;" id="table"> <tbody> <tr> <th scope="row">Profile No. : </th> <td>{{ProfileNo}}</td> </tr> <tr> <th scope="row">Name : </th> <td>{{Name}}</td> </tr> </tbody> </table> </div> <script> function hide() { document.getElementById("form").submit(); let table = document.getElementById("table"); if (table.style.display === 'none') { table.style.display = 'table'; } } </script> -

Django / Access to previous or next instance from the same class
My app starts with Scene1 Here is my Models.py where Scenes are defined class Scenes(models.Model): name = models.SlugField('Scene name', max_length=60,unique=True) description = models.TextField(blank=True) fileGltf = models.FileField(null=TRUE, blank=False, upload_to="3dfiles/") record_date = models.DateTimeField('Scene date') manager = models.ForeignKey( settings.AUTH_USER_MODEL, blank=True, null=True, on_delete=models.SET_NULL) prev = models.ForeignKey( 'self', related_name='next', blank=True, null=True, on_delete=models.SET_NULL) def __str__(self): return self.name The creation is ok.

Load foreign model instances into queryset.values()
I have queryset that groups and aggregates some data: EmployeeAssessment.objects.all().annotate(month=TruncMonth('assessment_date')).values( 'month', 'assessed_employee', 'subject' ).annotate(average_score=Sum('scores__score') / Count('scores__score', distinct=True)) And because of .values() I get assessed_employee and subject as IDs rather than model instances I know that there are some similar questions here, but they're all talking about single relation, that can be reversed to get the needed data from related model. My problem is that I need to get two nested objects: "assessed_employee" and "subject". Both of them are ForeignKeys I use DRF serializer like this: class EmployeeAverageScoreSerializer(Serializer): month = DateField() assessed_employee = EmployeeSerializer() # <- ModelSerializer subject = AssessmentSubjectSerializer() # <- ModelSerializer average_score = FloatField() It is ok if I will have some subqueries or something, but I need a single queryset that still can be paginated. How can I load models by ID after applying ".values" or maybe what other way can I use to get that data without losing model instances in resulting queryset? -

How to reduce size of input box in html used in django

Web app such as libgen using Python and SQL?
I'm trying to make a webapp almost like the website libgen essentially using Python that can access a MySQL database and query and search through the database in order to find what they are looking for. I'm a bit stuck on how to approach this as I believe using Django as a framework to access the database would be good but I can't seem to understand how to connect the database (which I have locally) to the project. But then I would need to be able to move this online for hosting. I would really appreciate the help. -
Null value in column violates not-null constraint after deleting objects incorrectly
Help me please I don't know what's going on. I wrote some simple blog, where I could add posts and comments. It was working well. views.py: def add_comment_to_post(request, pk): post = get_object_or_404(Post, pk=pk) # calls the given model and get the object, type = <class 'blog.models.Post' if request.method == "POST": # if we posted data form = CommentForm(request.POST) if form.is_valid(): # if all fields are filled comment = form.save(commit=False) # create instance and return which not saved in database "Comment" <class Comment> comment.post = post # return Title comment.author = request.user comment.save() return redirect('post_detail', pk=post.pk) else: form = CommentForm() # type = <class 'blog.forms.CommentForm'> return render(request, 'blog/add_comment_to_post.html', {'form': form}) But when I added a function for deleting comments, that wrote me a mistake, like this: null value in column "approved_comment" of relation "blog_comment" violates not-null constraint views.py: def comment_remove(request, pk): post = get_object_or_404(Post, pk=pk) comment = get_object_or_404(Comment, pk=pk) print(comment) comment.delete() return redirect('post_detail', pk=post.pk) I think I deleted comment incorrectly. I don't understand how primary keys works, how comments and posts are related each other. And I don't understand how to understand it. -

Django makemirgations not updating database
When I make changes to models.py, I am expecting django to update the database structure for me when I run python3 manage.py makemigrations or python3 manage.py makemigrations appname. It doesn't detect any changes. I have had this issue once before and had to delete everything in the database to update it, which seems a bit drastic. What am I doing wrong?

Show different pages based on user - django
I'm building a web app IMDB's like. Each (logged) user views the same exact homepage, but they can flag/unflag every movie they want to save them in a "seen list". I've done that but I've noticed that every user logged can view the other user's flagged movies. Of course this is a problem, so I'd like to build a page relative to each user, so that everyone would have different "seen films" page based on the movies flagged as seen. The main idea behind this, is that whenever a user adds a movie to the database, he can flag it as seen with a simple models.BooleanField in the model of the film. I have then another model "Seen" where there are all the movies flagged. models.py class Films(models.Model): ... seen = models.BooleanField(default=False) class Seen(models.Model): ... views.py films = Films.objects.all() for film in films: flag = 0 seen_films = Seen.objects.all() for _ in seen_films: if film.name == _.name: flag = 1 break if not flag and film.seen: act_seen = Seen(image=film.image, name=film.name, description=film.description) act_seen.save() I need to add that for the user, I use the default class provided by django: from django.contrib.auth.models import User I get that the error is everyone can … -

Selenium authentication without sharing credentials

How do people go about this? -

Error H12 Heroku with Django bot scraping app
I have a bot made in Django and I want to run it on Heroku. The project's HTML template opens in Heroku just fine. This template has a form and a submit button. When I press the button, what is written in the form is sent to the main function of the bot and uses it during scraping. The problem is that the bot takes about 4 minutes to perform the functions and the Heroku router only executes requests for 30 seconds. I have searched for a thousand solutions on the internet but no matter how much I apply one after another I can't find it. I have also contacted Heroku support and they told me that I can use New Relic for long-runninf actions and use a background worker as well. I've tried setting both and I can't get around the H12 error either. Could someone tell me how to configure the worker and New Relic correctly? Many answers I find with this are old or I can't optimize it for my project. Thank you.
