Validation errors don't appear in Django form
I am trying to create a form where the users will enter their emails. Typically the validation errors for email(empty field or not proper format) are displayed by the browser. Using the basic form example, everything shows correctly: <form action="/notify-email/add/" method="post"> {% csrf_token %} {{ form }} <input type="submit" value="Submit" /> </form> In my case, if there are no validation errors I use an ajax request to save the email and show a modal with a thank you message.But if there are validation errors I can see them when only if I hover. Also, the modal is shown even if there are errors in validation. This is my models.py: from django.db import models class NotifyEmail(models.Model): email = models.EmailField(max_length=255) date_added = models.DateField(auto_now_add=True) time_added = models.TimeField(auto_now_add=True) def __str__(self): return self.email This is the form based on the model: from django import forms from landing.models import NotifyEmail class NotifyEmailForm(forms.ModelForm): class Meta: model = NotifyEmail fields = ["email"] def __init__(self, *args, **kwargs): super(NotifyEmailForm, self).__init__(*args, **kwargs) self.fields['email'].widget = forms.EmailInput(attrs={'placeholder': 'Email', 'required': True}) My views.py: from django.shortcuts import render from django.http import JsonResponse from .forms import NotifyEmailForm def add_notify_email(request): if request.method == "POST": form = NotifyEmailForm(request.POST) if form.is_valid(): form.save(commit=True) print("Email Added.") return JsonResponse({'msg': 'Data saved'}) else: … -
setting permission for only one object using Django-guardian and Flatpages
I'm trying to use Django-guardian to apply permissions to specific flatpages. we have a number of flatpages on our site, and in most cases the django-auth works for what we need. However, we want to add object level permissions to some of the flatpages and specific users. for example, i have a user YOUNGTEMP and i want to give this user access to edit a subset of the total flatpages we have on the site. I have installed Django-guardian, and using the shell given change_flatpage permissions to this user for the appropriate sites. this user has no other permissions at all, as i don't want them to see anything but this one site from the admin. I can verify by looking at the DB that the permissions are there, as well as that they appear in the admin when i log in as a SU. Why then when i log in as this user YOUNGTEMP does the admin site tell me i have no permissions to edit anything? I followed the excerpts from the readthedocs.io page here to assign permissions in the shell to make sure it wasn't a problem with my overridden admin, which looks like this: imports*... class … -

Better way to create class dict entries from a loop than locals()
I've been told it's bad form to use locals() to dynamically create variables in Python. However, I'm writing a class (using Django and Wagtail), and I really do need these things to go in the class dict, a.k.a. the class statement's local variables, not in a separate data structure: class BlogPage(Page): for language in languages: locals()['body_' + language] = RichTextField(blank=True) I don't think I can set these after the class statement with setattr, either, because Django's metaclass processing will already have happened by then. Is there a better way? -
Django Calculated Fields
I am making a website for which you can sell goods online and I am using Django. I am unsure how to proceed with a section. The four models involved are Good_For_Sale An item would be listed on the sale which lists type, description and other specs, but relevant it would list a price Customer A customer should be able to fill out a form and order an item on sale Orders A customer may order an item and this is stored in an orders fields It can store order status at the time Invoice Once the goods are delivered then the invoice is produced and sent for payment Requirement would be that one invoice may be for many orders and invoice is issued after the goods are delivered Invoice would be issued every 14 days (ie on the 14th and 28th of each month an invoice would be issued for all delivered orders) What I am having problems is: How to calculate an invoice total based on the basis of all delivered orders in the past 14 days How to calculate tax (assume mixed item supply where tax status is stored at good_for_sale level) Code Models.Py class Orders(models.Model): date … -
Using django flatpages without the Site framework
I'm currently working on flatpages for my website, however, I find it unnecessary having to configure my source code with SITE_ID and matching it with the database Site model, for the single reason that I wish to use flatpages on a single website. What I want is simply to lookup the url path in the database, for a match in a pages table, and output the relevant page information. Without having to configure. Is there any way I can get flatpages in the database without having to specify a site number and having an extra model in my database? The functionality of the flatpages that is prebuilt is great, I just want to remove the need for Site, and hardcoding. -

How could I use an HTML code to store data in a django based app?
So I have been trying to design an app that can take the file input from two csvs, then combine them into a dataframe and analyze them. The python function to do this is done, but there is an issue with uploading them onto the app. The django based app system that I am writing the app on has gizmos, but none of the gizmos are used for file input. So I put this code in the django template: <div class="gauge-data-upload"> <label class="control-label" for="gauge-data-upload-input">Recorded Gauge Data</label> <input id="gauge-data-upload-input" name="gauge-data-upload-input" type="file" accept=".txt,.csv"> <p class="help-block hidden">Must select file to submit!</p> </div> But I am uncertain how to link this html code to the controllers page (a page of python classes) This is what my controller for this particular django template looks like. @login_required() def add_gauge_data(request): """ Controller for the Add Dam page.

How can I authenticate user both in websockets and REST using Django and Angular 4?
I would like to authenticate user both in websockets and REST using Django and Angular 4. I have created registration based on REST API. User after creating an account and log in can send messages to backend using websockets.

Issue with DecimalField,max_digits of django models
I have declared below field in models.py "marks = models.DecimalField(max_digits=2, decimal_places=2, default=3.0)" At backend table structure is | Field | Type | Null | Key | Default | Extra | | marks| float(3,1) | NO | | 1.0 | | So here default value 3.0 will try to save as 3.00 (decimal places=2) at backend and there will be no space to store left side value 3 right? For above case,when I give max_digits=3 or decimal_places=1 it is working. Please help me,what exactly happening here from django to mysql db flow? -

How to add a confirmation page to an email form in django? Problems with django formtools or session data.
What I want to accomplish I want a page where user fill a form to send an email (to multiple recipients). Before sending, the user should see the hole email an all recipients and should confirm the sending or go back and edit it. What I have tried Using django formtools. https://github.com/django/django-formtools https://django-formtools.readthedocs.io/en/latest/ The Problem Formtools seems to only work if I derive the form from a model and I see no reason to do that. What I have else tried Saving the input in request.session. The Problem Recipients are a list of objects (ModelMultipleChoiceField). In request.session I can only save JSON data. Thus I can not serialize it. I could extract the email addresses of the recipients list but if the user wants to go back to the form I can not prefill the ModelMultipleChoiceField. So I ran out of ideas. -
