Is there anyway in django to create the form such that when users select on one choice it will show another set of choice that users can select on
I want to create the form such that when users select on one choice it will show another set of choices that users can select on (or show text field that user can write in). For example, if I have a form Use geographical feature Yes No When user select yes it will show another set of choices under "yes" Use geographical feature Yes randomize fixed input No Is there any possible way to implement in django and how to embed it in django html template? I am quite new to the web-dev and django. So, I am not quite sure what to look for and Googling hasn't yielded me the answer I am looking for. -
Suggestions for splitting up a Django model of 1000+ fields
I am looking for suggestions on how to deal with a database table that has 1000 or more columns and I am tying to translate it into one or many Django models. The data also needs to be filtered through API calls within the URL. Every field needs to be able to filter the rest of the data. I have come up with a few solutions and would like input or resources related to them: Just have a model with 1000+ fields - This seems like it would be a nightmare to maintain and would require a lot of brute force coding but would likely work fine if data was selectively returned. Use a JSON field to store all less frequently accessed data - The issue here would be difficulty in filtering the data using Django Filters. Split data into related models connected by One-to-One relationships, as I understand this cuts down on join operations. - This would seem to require more coding than the first option but would be more maintainable. Does anyone have any information or resources on dealing with database tables of this size? -
Django form saves and fetches <QuerySet object> instead of values
I have a simple Django 3.1.0 app I need to create in order to assign Tasks with Tags (or assign tags into tasks). Model class Task(models.Model): user = models.CharField(max_length=33) time = models.DateTimeField(auto_now_add=True) task = models.CharField(max_length=500) tags = models.CharField(max_length=100, default="None", null=True) class Tag(models.Model): tag = models.CharField(max_length=30, default="No Tag") members = models.ManyToManyField('Task', related_name="tag") class Meta: verbose_name = "tag" verbose_name_plural = "tags" view def main(request): model = Task.objects.values().all() tags = Tag.objects.values().all() form = TaskForm() con = {'context': list(model), 'form': form, 'tags': list(tags)} if request.method == 'POST': form = TaskForm(request.POST) if form.is_valid(): form.save() return redirect('/') else: form = TaskForm() return render(request, "tasks.html", con) form class TaskForm(ModelForm): class Meta: model = Task fields = ['user', 'task', 'tags'] template_name = 'tasks.html' tags = ModelMultipleChoiceField( queryset= Tag.objects.all(), widget=CheckboxSelectMultiple(), required=False, ) task_form <form method="post" class="form"> {% csrf_token %} {{form}} <input type="submit" value="Save"> </form> This returns in the tags list the items listed as: Tag object (1) Tag object (2) And when it saves when i press submit, it fetches in a table (in another template), the values saved in the text of <QuerySet [<Tag: Tag object (2)>]> That's how it stores them in the database.

is there a way to create superuser for django apps on heroku without using CLI?
I changed my db of my app on heroku to not use the sqlite db that is the default for django app, to use the heroku postgres database. however, I want to login to my admin portal on my heroku app, but i am not sure how to create a superuser. Also, is there a way to push my local db to my heroku db? I have been deploying through github (not using the heroku CLI, so I was wondering if there was a way without using the CLI). if there isn't a way without using the heroku CLI, could someone tell me how I would init the heroku git repository, considering the fact that I already have a GitHub repository that I have been using (I am not great with git). this is my settings.py: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': BASE_DIR / 'db.sqlite3', } } import dj_database_url db_from_env = dj_database_url.config(conn_max_age=600) DATABASES['default'].update(db_from_env) -
How to handle a site wrapper and in Django templating?
I have a Wagtail site with the following structure: <html> <head> </head> <body> <div id="site-wrapper"> <div id="site-canvas"> <div id="site-navigation"> </div> <div id="site-mobile-navigation"> </div> <div id="content"> </div> </div> </div> </div> </body> </html> I would like to use the {% extends "base.html" %} command to utilize the above HTML structure within a site wide template, but I'm not sure how to handle extending exclusively within the the <div id="content"> element. The hope is that the navigation, header, body, etc., could all be placed in a template but that I could begin the Wagtail pages starting within the 'content' div. -

Django views and HTML form
I have created a form in HTML and I want to bind it to a model, but I do not know how to make it possible to select a form from the database data by the type of a drop-down list.

Moving password validation errors for Django UserCreationForm, from password2, to password1
I've got a Django form class, that inherits from the built-in UserCreationForm. I'm working on submitting the form using AJAX, and returning the bound form (including errors) as rendered HTML if it doesn't validate. Something puzzling me is that the errors relating to the password (e.g. too short, common password...) appear for the password2 / confirmation field. Here's a screenshot of the default behaviour: From a UX perspective I feel as though it would be more useful for the errors to appear for the first password field in the form, so users can adjust that one, then confirm it by typing it again below. I've noticed that in UserCreationForm, clean_password2(), doesn't actually validate the password, it just checks that password1 and password2 match. Then in the _post_clean() method, password2 is validated, and any errors are added to that field. In my attempt to change it, I have overridden _post_clean() as follows: def _post_clean(self): super(forms.ModelForm, self)._post_clean() password = self.cleaned_data.get('password1') if password: try: password_validation.validate_password(password, self.instance) except forms.ValidationError as error: self.add_error('password1', error) I don't want to call super, and have it validate and send errors to password2, so I am calling the post_clean method of the grandparent (ModelForm) instead (I think!), to not … -

Using ```localStorage``` to store dynamically created buttons in Javascript
My goal is to have the user enter values which then generates a button. They should be able to continuously enter values and new buttons should be created following each entry.

Concatenate Javascript for variable with django variable
Good afternoon, I have a javascript block that I would like to iterate and get a Django variable based on the index. How can I do this in a javascript block on django template?

Django: How to render data in tamplate from another template on button click
I would like to ask for help for my following issue: I have a template on the "Customer" side and template on the "Staff" side where both are in different django apps. Now..from Customer page I am via Ajax (button click) sending data to two different views (Customer and Staff) and saving objects to database . It is working but as you can see the Staff page will render data from Customer only When Loading the page. How I can render real time data on Staff page every time Customer will press the button either from view or from database? I believe I should use Django Channels for this purpose and I actually manage to get to work a test Chat room but I have no idea how I could implement it for my case. I am not an advance developer as you can see. Thank you in advance. -

Django/Python: update item in list
Hey so I am new to django/python and I want to create a to-do-app. I already have the basic structure, I can add a task, it is shown in my list and I can delete it. So I already have the C, R, and D from the CRUD features :-) Now I want to be able to update a task that is already in my list. So e.g. if I have a task called "laundry" I want to be able to click on it and change it to "do laundry" and save it. Or something like that. I have no idea how to to this or if it is possible. Maybe you can give me some inspiration (I want to do it myself so I don't need full code solutions). I am just kinda stuck and need somewhere to start... Thanks a lot in advance! -

When i open browser then it is showing me :- local variable 'comment_form' referenced before assignment views.py def detail_view(request,id): data = get_object_or_404(Post,id=id) comments = data.comments.order_by('-created_at') new_comment = None if Post.allow_comments == True: if request.method == 'POST': comment_form = CommentForm(data=request.POST) if comment_form.is_valid(): comment_form.instance.post_by = data comment_form.instance.commented_by = request.user comment_form.instance.active = True new_comment = comment_form.save() return redirect('mains:detail_view',id=id) else: comment_form = CommentForm() else: print("Comments are Disabled") context = {'data':data,'comments':comments,'new_comment':new_comment,'comment_form':comment_form} return render(request, detail.html', context ) models.py class Post(models.Model): creater = models.ForeignKey(User,default='',null=True,on_delete = models.CASCADE) date_added = models.DateTimeField(auto_now_add=True,null=True) description = models.CharField(max_length=10000,default='') allow_comments = models.BooleanField(default=False) detail.html <div class="container"> <form method="post" enctype="multipart/form-data"> {% csrf_token %} </div> <div class="col-6"> {{ form.description }} </div> </div> <br> {{ form.allow_comments }}<p>Allow Comments</p> <br> <br> <button type="submit">Add this Post</button> <button type="reset" value="reset">Reset Everything</button> </form> </div> I don't know .

How can i save Multiple items in database using FileField in Django?
i want to upload multiple files from Django FileField. The code below upload single file instead of multiple files. i also define for loop for file data but i don't understand how can i files save in database? I would be grateful for any help. Views class NewsCreateView(CreateView): form_class = ArticleForm template_name = 'create.html' success_url = '/' def form_valid(self, form): form.instance.author = self.request.user for f in self.request.FILES.getlist('file_data'): # file_data it's an a Attribute instance = form.file_data = f instance.save() return super().form_valid(form) -
How do I change the 'name' HTML attribute of a Django Form field?
I have a Django 3.0 form # forms.py class SignupForm(UserCreationForm): email = forms.EmailField() This renders as the HTML element <input type="text" name="email" required id="id_email"> Is there a way to change the 'name' attribute? The widgets documentation suggests that either of these might work: # forms.py class SignupForm(UserCreationForm): email = forms.EmailField( widget = forms.TextInput( attrs = {'name': 'email_address'} ) ) or # forms.py class SignupForm(UserCreationForm): email = forms.EmailField() email.widget.attrs.update({'name': 'email_address'}) but both render with two name attributes; the first one isn't replaced: <input type="text" name="email" name="email_address" required id="id_email"> Is there a straightforward method of changing the name attribute? I've found a couple of related previous posts, but the questions and answers tend to be old (Django 1.0-era) and more convoluted than this process ought to be. I'm hoping that newer versions have a simpler solution.
