How to check and keep checkboxes checked when others are unchecked
I have check boxes that when I check 3of them for example and then I uncheck 1, an attribute works in the opposiste. With this I mean that Because I have a default hidden button that appears when I check a checkbox, when I hav e 3 of the checkboxes checked and I uncheck 1, the button is hidden where as 2 checkboxes are still checked meaning that the button should be unhidden. How would I correct this???? <script> $(document).ready(function() { $('#select-all').click(function() { var checked = this.checked; $('input[type="checkbox"]').each(function() { this.checked = checked; }); }) }); //Add a JQuery click event handler onto our checkbox. $('input[type="checkbox"]').click(function(){ //If the checkbox is checked. if($(this).is(':checked')){ //Enable the submit button. $('#delete_all').attr("hidden", false); } else{ //If it is not checked, hide the button. $('#delete_all').attr("hidden", true); } }); </script> <form method="post" action="{% url 'delete_students' %}"> {% csrf_token %} <table class="layout container"> <thead> <th><input type="checkbox" id="select-all"></th> </thead> <tr> <td> <input type="checkbox" name="marked_delete" value="{{ student.pk }}"> </td> </table> <button class="btn btn-dark" id="delete_all" hidden="hidden">Delete Selected</button> </form> -

How to display django forms in a table format?
I have the following in my Models.py class Accounts(AbstractBaseUser, PermissionsMixin): first_name = models.CharField(max_length=150) last_name = models.CharField(max_length=150) .... is_assigned = False class Section(models.Model): name = models.CharField(max_length=150) .... is_assigned = False is_teacher = False class Assignment(models.Model): teacher = models.ForeignKey( Accounts, on_delete=models.CASCADE, limit_choices_to={'is_teacher': True, 'is_assigned': False} ) section = models.ForeignKey( section, on_delete=models.CASCADE, limit_choices_to={'is_assigned': False} ) Now I'm trying to assign a teacher to a section and I'm using BSModalModelForm in my forms.py but as I'm writing my code I'm starting to get lost. How can I display my form in this format? Note: All teachers that are not assigned are displayed in the table. Thank you for answering! -
How can I check the file names through python a script in python?
I am using python scripts to save web scraped data to CSV files. The name of CSV files is dynamic, like fl_todays_date.csv where today's date is the date derived from the web scraped site. After saving the data in a CSV file, I then import the CSV data into my Django models, all through the script. But the problem I'm facing is, How can I check whether the data from yesterday's file is already present in the database before importing today's data. My file structure is as follows: csv_files fl_some_pervious.csv fl_yesterday.csv fl_today.csv script scrape.py db_upload.py -

In a Django template, can I use a button to update the data in an HTML table generated with a for loop?
Let's say I've used the following syntax to create tables in a Django template: {% for data in list_of_data_dicts %} <tr> <td> data.col_one_val </td> <td> data.col_two_val </td> <td> data.col_three_val </td> </tr> {% endfor %} I also have several such 'list_of_data_dicts' representing datasets of the same form. I would like to be able to update which dataset is used to populate the table with a button click. How can I accomplish this? -

What else can I try to debug a "ModuleNotFoundError" in Django?
I’m having problems with one module in my Visual Studio Core project. It is not being found. It generates this error: File "C:\Users\danj\source\repos\project_django\comstockapt\comstockapt\urls.py", line 28, in from comstockapt.email_accounts import views as email_views ModuleNotFoundError: No module named 'comstockapt.email_accounts' I’ve gone through many, many similar questions, but I can’t get it to work. I’m using the virtual environment. When I execute “python” in the terminal and then run ‘help(“modules email_accounts”)’ it shows the module with all of its files. When I run help(“modules”), I see all of my modules listed in the response. Here is my urls.py file within module comstockapt.comstockapt. Here is my installed_apps: I've checked environment variables, the virtual environment, the directory structure. What can I try next? -
Partial updating a ManyToMany field, but keeping its get representation
I've been scratching my head about this problem for a couple of hours now.

Filter in Django array
How do I filter an array with a property from a model? class InvestorCountry(SimpleListFilter): """ This filter is being used in django admin panel in Investor model.

Checking if user exists and using its data if it does
I have a view in which the user has to fill either the email or phone fields and then choose a pizza from an items list. The thing is, if the user enters an email or a phone then I need to check if the email or phone match an existing user (if it does, then the order uses that one, if not then no user is used). But if the user enters both fields and the user exists then I use that one and, if not, I create it. Since I'm doing all of this through a view that connects to the order serializer that is connected to the order model, I am not sure how I can implement this, since the user's data is connected to its own serializer and model. I am new to this type of thing so any advice on how to tackle this would be very appreciated. I wrote something in my view that does not work but should illustrate what I mean... maybe there's a way to do it like that but make it work? These are the models: class Client(models.Model): email = models.EmailField(max_length=200) phone = models.IntegerField() def __str__(self): return self.email class Order(models.Model): … -
Django, template. Can't pass variable inside if statement
I am using django all auth to sign in with my Google accounts. I'm able to get {userName} to display on the template. I also created a table and pass {userName} as a hidden field. When I try to match {userName} to match the table's userName in my if statement to only display certain rows of data, nothing shows up. I can't get {userName} directly in my view and pass it on to my template because django all auth uses different views. -
Passing authenticated_user kwargs to Django Form with Class-based View
I have a Django application to track referrals (referred by a user). I want to pass the id of the authenticated user to the ModelForm 'referrer' field (and since it's from the current logged in user the field shouldn't be editable). class Referral(models.Model): name = models.CharField(max_length=100) referrer = models.ForeignKey('users.User', on_delete=models.SET_NULL, related_name='referrals', null=True, blank=True) View: class ReferralFormView(FormView): form_class = ReferralForm template_name = "refer.html" success_url = reverse_lazy('thanks') def get(self, request): if request.user.is_authenticated(): return super(ReferralFormView, self).get(request) else: return redirect('login') def get_form_kwargs(self): user = self.request.user form_kwargs = super(ReferralFormView, self).get_form_kwargs() form_kwargs['referrer'] = user.id return form_kwargs def form_valid(self,form): ... form.save() return super(ReferralFormView, self).form_valid(form) I override get_form_kwargs in the view, then modify form init class ReferralForm(forms.ModelForm): class Meta: model = Referral def __init__(self, *args, **kwargs): referrer = kwargs.pop('referrer', None) super(ReferralForm, self).__init__(*args, **kwargs) self.fields['referrer'].disabled = True self.fields['referrer'].queryset = User.objects.filter(id=referrer) However all I see is a blank referrer field, what am I missing to pass the user id to that field? thanks -
Parse Nested Url Encoded Data from POST Request
I am creating a callback URL in Django for a webhook in Mailchimp. Mailchimp sends a POST request to the URL whenever certain actions are performed on users in Mailchimp. These POST requests contain data in the body in the form application/x-www-form-urlencoded. Mailchimp does not provide an option to choose the format of the data returned, so we must use the URL-encoded data. Now, the issue is that the data returned contains nested data. That is, lists and dictionaries (or JSON, since it is an HTTP request), are in the url-encoded data. For example, one POST request from Mailchimp, which is sent when a user changes their name, would look like: type=profile&fired_at=2021-05-25+18%3A03%3A23&data%5Bid%5D=abcd1234&data%5Bemail%5D=test%40domain.com&data%5Bemail_type%5D=html&data%5Bip_opt%5D=0.0.0.0&data%5Bweb_id%5D=1234&data%5Bmerges%5D%5BEMAIL%5D=test%40domain.com&data%5Bmerges%5D%5BFNAME%5D=first_name&data%5Bmerges%5D%5BLNAME%5D=last_name&data%5Blist_id%5D=5678 Using Django's request.POST, the data is decoded into: type=profile&fired_at=2021-05-25 18:03:23&data[id]=abcd1234&data[email]=test@domain.com&data[email_type]=html&data[ip_opt]=0.0.0.0&data[web_id]=1234&data[merges][EMAIL]=test@domain.com&data[merges][FNAME]=first_name&data[merges][LNAME]=last_name&data[list_id]=5678 This is less than optimal, since to access the first name of the user from this data we would have to write request.POST.get("data['merges']['FNAME']", None) when the data is intended to be accessed more like data = request.POST.get('data', None) try: first_name = data['merges']['FNAME'] except KeyError: first_name = '' I have looked for a Django/Python specific way to decode this nested URL-encoded data into more appropriate formats to work with it in Python, but have been unable to find anything. … -

ModuleNotFoundError: No module named 'psycopg2' error: python3, django, settings.py?
First of all, I've read I think all the most recent (2019 onwards) posts here about this problem to no avail :( I've got an up&running default webapp with python3 and django already working with default db.sqlite2. I now neeed to change all that db backend to psql. So, from these sources: https://pypi.org/project/psycopg2/ https://www.psycopg.org/docs/install.html I've installed psycopg2-binary, OK. From this source: https://www.enterprisedb.com/postgres-tutorials/how-use-postgresql-django I've modified settings.py, DATABASES section, to use psql instead of sqlite. I've tried: 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'ENGINE': 'django.db.backends.postgresql', And both gives me the error: (env) PS D:\Users\llagos.NB-KEYONE15\Visual Studio projects\ecommerce-psql> python manage.py makemigrations Traceback (most recent call last): File "D:\Users\llagos.NB-KEYONE15\Visual Studio projects\ecommerce-psql\env\lib\site-packages\django\db\backends\postgresql\base.py", line 25, in <module> import psycopg2 as Database ModuleNotFoundError: No module named 'psycopg2' ... django.core.exceptions.ImproperlyConfigured: Error loading psycopg2 module: No module named 'psycopg2' So, what's wrong with this settings.py file? is this correct? I've tried to google for information but again, no luck. Documentation for psycopg2 doesn't say what to change on settings.py. It just say "install and code", but when using django, there are previous steps, like this settings.py file. Thanks a lot for any hint! Regards, -
Django changing model value based on relationship with other model
I'm working on a project that has three models, one of which has a value that is dependent on if the other two are linked to it by a foreign key. the value can also switch if the links change. I was wondering how I would go about that.
