How do I customize the "username already exists" message?
My forms.py has a custom user-creation class... class RegisterForm(UserCreationForm): error_messages= { "password_mismatch": _("Passwords do not match."), } To clarify, I do not know which error_messages key corresponds to the one Django spits out when a user tries to sign up with a username that already exists. Which error message do I need to replace for when the user chooses a username that already exists? -
Escape additional characters with Django autoescape
I'm trying to extend Django default autoescape behavior to escape the {} characters. The issue is our Django templates are printing inline JS templates (angular.js). But this means some variable django prints might contains {{}} characters that are going to be executed - thus allowing XSS. We're usually doing escapes and backend validation, but some old pages might've skipped the basic checks. Any chance we can hook directly in the autoescape behavior to also HTMl encode those extra characters automatically? -
Where do I run the terminal from when I deploy my django app from a public server?
So at the moment I run my django app in a virtual environment locally. I go to my project root an perform source bin/activate and now I am running my projects terminal from there. My question is where do I run the terminal when I deploy my app on a public server? Lets say I deploy my app on Digital Ocean with Nginx & Gunicorn. On what platform do I run the terminal through? And how do I activate it similar to how I activted my virtual env? -
How to get input value from templates and store to database [Django]
I'm trying to get {{ id }} when user clicks on movie and save it to models. I can't use modelForm because id parameter comes from html template. Any suggestions? Maybe, there is a different way to get an id of that movie user clicks?

child node is treated as grand child node when trying to structure
I am using django-mptt library for the category. I could show the list of categories in template but I wanted to indent it properly so user can know which is a main category and which one is sub-category and etc. The way i tried to structure is {% recursetree nodes %} <li class="node"> <a href="/category/{{ node.get_absolute_url }}" class="{% if not node.is_leaf_node and not node.is_root_node and node.is_child_node %} child_parent {% elif node.is_leaf_node and not node.is_root_node %}leaf_node{% endif %}"> {{ node.name }} {% if node.is_root_node %} <span class="badge">{{ node.get_count_children }}</span> {% endif %} </a> {% if not node.is_leaf_node %} <ul class="children"> <li>{{ children }}</li> </ul> {% endif %} </li> {% endrecursetree %} This yields the following design of category Here Dressing Table is a child of Bedroom Items like Bed and Almirah not a child of Bed. How could i fix this? I know the problem is here <a href="/category/{{ node.get_absolute_url }}" class="{% if not node.is_leaf_node and not node.is_root_node and node.is_child_node %} child_parent {% elif node.is_leaf_node and not node.is_root_node %}leaf_node{% endif %}"> but could not fix this issue -

NoReverseMatch when it has not to occur
everyone! I'm new to Django and actually making a study project. I'm getting a NoReverseMatch exception and can't understand why. It seems not to have namespace conflicts, the other list views are made in the same way as for the StoredItem model, but only this one throws an exception: models.py: from django.db import models from django.urls import reverse # Create your models here. class LegalEntity(models.Model): name = models.CharField(max_length=100, help_text="Name") rif = models.CharField(max_length=10, help_text="RIF") address = models.TextField(help_text="Address") phone_num = models.CharField(max_length=15, help_text="Phone number") def __str__(self): pass class Contract(models.Model): name = models.CharField(max_length=100, help_text="Name") number = models.CharField(max_length=50, help_text="Contract number") description = models.TextField(help_text="Contract description") start_date = models.DateField(null=False, blank=False, help_text="Start date") expiry_date = models.DateField(null=True, blank=True, help_text="Expiry date") def __str__(self): return "number: {0}, " \ "name: \"{1}\", " \ "starts: {2}, " \ "expires: {3}."\ .format(self.number, self.name, self.start_date, self.expiry_date) def get_absolute_url(self): return reverse('contract-detail', args=[str(self.id)]) class Provider(LegalEntity): contract = models.ForeignKey(Contract) def __str__(self): return "name: \"{0}\", " \ "RIF: {1}, " \ "phone: {2}."\ .format(self.name, self.rif, self.phone_num) def get_absolute_url(self): return reverse('provider-detail', args=[str(self.id)]) class Item(models.Model): name = models.CharField(max_length=100, help_text="Name") serial = models.CharField(max_length=50, help_text="Serial No.") manufacturer = models.CharField(max_length=50, help_text="Manufacturer") provider = models.ForeignKey(Provider) def __str__(self): return "name: \"{0}\", " \ "serial: {1}, " \ "manufacturer: {2}," \ "provider: {3}."\ .format(self.name, self.serial, self.manufacturer, … -
Django: redirect to DetailView without pk in URL

Create ModelChoiceField with annotation
I need to make a selector with genders (male and female) with the respectives counts of each type. For example, if I have 4 males and 8 females in my DB, I need a select tags with options "Select gender" "Male (4)" "Female (8)" In my Form class I have gender = forms.ModelChoiceField( queryset=Gender.objects.all().annotate(counter=Count('user')), required=False, label="Gender" ) And I don't know how to render this select element. If I use {{ form.gender }} I can't even display the options. I get Error binding parameter 0 - probably unsupported type. It could be an SQLite issue? I will use PostgreSQL as my DB anyway. Any suggestions? -

Get a dynamically changing django modelform based on user input
Django noob here. I'm trying to learn how to implement a modelform that based on a fkey for an event, can accept multiple items a user is trying to sell at an event. Here is my models.py: class seller_event_items(models.Model): item_id = models.AutoField(primary_key=True) event_id = models.ForeignKey(seller_event) item_name = models.CharField(max_length = 300, default = 'Null') item_price = models.CharField(max_length = 300, default = 'Null') item_quant = models.CharField(max_length = 300, default = 'Null') def __unicode__(self): return str(self.item_id) + str(self.event_id) So what I'm trying to do is: 1. Accept a form where the user creates an event. This can be part of the same html form or not. I can figure that out separately. 2. Get the event_id as foreign key and then let the user input as many items as they want for that event by clicking an html button to multiply the item fields. So for example, the html form first only contains fields for 1 item. Then the user presses a button and fields for another item gets added dynamically and so on. Any suggestions on how I could go about doing this? Thanks in advance! Let me know if I should add any more details. -

Dynamic form field rendering/validation
I’ve been trying to come up with a scalable solution for a dynamic form. The problem is that the form itself has a tree structure similar to: A / | \ B C D / \ / \ E F G H Each level is a different panel, containing a number of fields that may or may not have dependencies on lower levels. The problem comes in when a field E is directly dependant on B, but a user can pick C or D at any given point, removing the choice/flow selected (E). I believe for this solution a tree would be best to use, but that approach becomes increasingly complex to handle and maintain as more options can be introduced for any level, specifically the first one. The most efficient solution I’ve found is to use nested dictionaries to map the different dependencies, but this proves to be a very costly method in terms of updating the structure to handle new fields or existing fields differently, since all of the logic would need to be readded. Is there a library/known solution to this problem? -
Django Form Logic: Split and display prefilled values
Let's say I have a model that holds several different charfields. models.py class Items(models.Model): languages = models.Charfield(...) settings = models.Charfield(...) audio = models.Charfield(...) The data is saved within each with a delimiter ("||"). I would like to create a form that splits the data then prefills the value with the saved data. Theoretically: {'languages': 'English||French||German'} {'settings': '1.1||1.1||2.0'} {'audio': 'yes||no||yes'} Would be split to: {'languages': ['English', 'French', 'German']} {'settings': ['1.1', '1.1', '2.0']} {'audio': ['yes', 'no', 'yes']} Then each value would auto-populate the value field. Eventually displaying as: <tr> <td><input type="text" name="languages[]" value="English"></td> <td><input type="text" name="settings[]" value="1.1"></td> <td><input type="text" name="audio[]" value="yes"></td> </tr> <tr> <td><input type="text" name="languages[]" value="French"></td> <td><input type="text" name="settings[]" value="1.1"></td> <td><input type="text" name="audio[]" value="no"></td> </tr> ... As each row would have a different amount of 'languages', for example, what is the preferred way to create this type of form. I am using Django 1.11. First question posted, so if I have missed something within this post, would you kindly let me know? I also have searched for information related to this, however I have yet to find a solution. Thanks! -

How to use icontains in a key value of a DictField in Django queryset?
Given the following model: class Team(models.Model): name = models.CharField(max_length=50) others = DictField() And the following code: bahia = Team() bahia.name = "E.C. Bahia" bahia.others = {"title": "Ninguém nos Vence em Vibração!!!"} bahia.save() vicetoria = Team() vicetoria.name = "E.C. Vicetoria" vicetoria.others = {"title": "Vice de tudo!"} vicetoria.save() I want to find the object that have the word vence, (case insensitive) contained in title value of the field others. I tried something like: teams = Team.objects.filter(others__title__icontains="vence") that gives me the following error: FieldError: Join on field 'others' not permitted. Did you misspell 'title' for the lookup type? I also already tried: teams = Team.objects.filter(others__icontains={"title":"vence"}) that returns None and I know there is at least one collection as result. How can I solve this? Thanks for your help. -

django creating generic class to validate User authentication

How do they translate from local development to when using a public server? -
'WSGIRequest' object has no attribute 'some_attribute'
I am trying to render html to pdf and include it as a django action, however, for some odd reason, I seem to keep getting the issue that the object has no attribute 'some_attribute'.

How to override Model.objects.all() to a subset of the same globally
The Scenario I'm developing a web application that will store multiple Organizations and each organization has it's own users. For me an organization is a domain and the domains can't see each others at database level. Instead of creating N databases/views to simplify the management and speed up the performances I store the data of all organizations onto the same database. The Goal What I want to implement is a simple way to retrieve the data from my database that are already filtered by domain. Since each domain belongs to an User (or vice versa) the first option that come in my mind is to use a queryset defined in this way: def MyCustomViewSet(viewsets.ModelViewSet) queryset = Model.objects.all(domain__iexact=request.user.domain) I can't use this solution because it forces the developer to filter all queries manually all around the web application. If for some reason someone forget to properly filter queryset, the users of an organization can see the data of other organizations (and vice versa) - It's error-prone. Using thread locals Since I can find the user inside the request another solution would be to expose the request through a middleware and automatically filter by domain using the domain of the user that … -
