DoesNotExist --Matching Query Error
I'm trying to list a group of deals by category I have a Deal model and a Category Model, where the Category is a Foreign Key of a Deal like so: class Deal(models.Model): title = models.CharField(max_length=200) slug = models.SlugField(max_length=140, unique=True) description = models.TextField(default='') category = models.ForeignKey(Category) The urlpattern for a category page looks like this: url(r'^category/(?P<category>\w+)/$', deals_by_category, name='category') The view for this urlpattern is this: def deals_by_category(request,category): category_deals = Deal.objects.filter(category__name=category, ) return render(request, 'deals/category.html', {'category_deals': category_deals}) and then my category.html template is looping through these returned deals like this: {% for deal in category_deals %} <h5 class="card-retailer">{{ deal.retailer}}</h5> <p class="card-title">{{ deal.title }}</p> Now the issue arises if i click on predetermined category link like this: http://localhost:8000/deals/category/Apparel/ but the error is pointing NOT to my 'deals_by_category' view, but to the individual view for each deal---the stack trace is pointing to that second line below. I think this must be an easy fix, but have been staring at this for the past few hours and can't determine what the issue is. def deal_by_detail(request, slug): deal_detail = Deal.objects.get(slug=slug) return render(request, 'deals/deal_detail.html', {'deal_detail': deal_detail}) -
Django sort and regroup multiple fields
I am trying to regroup a field and sort on another in Django. My use case is different, but let's use the Django regroup template as an example. Using this dataset. cities = [ {'name': 'Mumbai', 'population': '19,000,000', 'country': 'India'}, {'name': 'Calcutta', 'population': '15,000,000', 'country': 'India'}, {'name': 'New York', 'population': '20,000,000', 'country': 'USA'}, {'name': 'Chicago', 'population': '7,000,000', 'country': 'USA'}, {'name': 'Tokyo', 'population': '33,000,000', 'country': 'Japan'}, ] Using the regroup tag, this is the output: India Mumbai: 19,000,000 Calcutta: 15,000,000 USA New York: 20,000,000 Chicago: 7,000,000 Japan Tokyo: 33,000,000 How can I sort this information by population and yet still keep the grouping? This is the expected output that I would like to see: Japan Tokyo: 33,000,000 USA New York: 20,000,000 Chicago: 7,000,000 India Mumbai: 19,000,000 Calcutta: 15,000,000 How would one query the database to keep the groupings that are needed for reorder in the Django template to work properly and yet still maintain the sort order of population? How would this work on a date object instead of an int? -
DJango TypeError - JSFiles object is not reversible
I am trying to include this datepicket widget in my DJango version 2.0.2, but it raises error TypeError at /xuser/1/edit 'JSFiles' object is not reversible I have already looked around for similar errors in following threads What does it mean by object not reversible Django TypeError at /admin/ 'set' object is not reversible But these are just typo errors about urlpatterns and does not even disclose what reversible actually mean in python. The google search about reversible object does not yield anything more than the above threads. So, my question is, What does reversible object mean? How can I solve this issue? -

Django Channels Live Chat: AttributeError: 'Message' object has no attribute 'as_dict'
I've been following this tutorial to implement a live chat system into my Django project. so far it has gone well and i've fixed any issues which have come up but this one stumped me. 2018-02-26 19:45:34,241 - ERROR - worker - Error processing message with consumer TestApp.consumers.ws_receive: Traceback (most recent call last): File "/home/.virtualenvs/blog/lib/python3.5/site-packages/channels/worker.py", line 46, in run consumer(message) File "/home/.virtualenvs/blog/lib/python3.5/site-packages/channels/sessions.py", line 57, in inner return func(message, *args, **kwargs) File "/home/blog_dev/TutorsTalk/TestApp/consumers.py", line 23, in ws_receive Group('chat-'+label).send({'text': json.dumps([m.as_dict()])}) AttributeError: 'Message' object has no attribute 'as_dict' This error seems to only come up when websocket data is being received which is why when i'm trying to send data it is saved to the database.

Predefined django groups with custom permissions
I know in advance what groups of users will be. During development we often reset db that is obvious. But i wondering where is the best place to put this information and when put it to database cause i don't want to do that every single time via django admin by hand. I figure out something like this: I have simple map of perms on the basis of which I'm putting needed info to database via function. GROUP_PERMISSION_MAP = { user_constants.GROUPS.ADMINISTRATORS: { Bet: ['add', 'change', 'delete'], Transaction: [], User: ['add', 'change'], Category: ['add', 'change', 'delete'], BetInfo: ['add', 'change', 'delete'], }, user_constants.GROUPS.REGULAR_USERS: { Bet: ['add'], Transaction: [], User: ['change'], Category: [], BetInfo: ['add', 'change', 'delete'], } } def assign_perms_to_group(group: Group, model: Model, permissions: List[str]): permission_codenames = ['{}_{}'.format(permission, model.__name__.lower()) for permission in permissions] group.permissions.add(*Permission.objects.filter(codename__in=permission_codenames)) What are the best practice and how it should be done? Especially my questions are: Where this predefined groups with permissions should live (maybe exists some better way)? What is the best way and time to put it to database ? -
Adding to model with OneToMany and updating existing entries.
I have a couple of Django model questions. I am running the following code as a Django manage extension, which I am new to. 1) I am not certain my "Location.objects.get(city=key)" is correct for OneToMany in my add_server_to_db function. I suspect this is incorrect? 2) How can I harden this so if this is executed twice, it will update existing Server entries vs. error out? Django Server Model: class Servers(models.Model): name = models.CharField(('name'), max_length=128) location = models.OneToOneField('locations.Location', on_delete=models.CASCADE) ip_address = models.CharField(('ip_address'), max_length=128) date = models.DateField(auto_now=True) Django Location Model: class Location(models.Model): city = models.CharField(('city'), max_length=10) geolocation = models.PointField(('location')) Function: def add_server_to_db(data_dict): print(data_dict) for key, val in data_dict.items(): loc = Location.objects.get(city=key) m = Server( location=loc, name=val['name'], ip_address=val['ip_address'], m.save() Thanks. -
Django - How to fix unique constraint fields
I'm making a hobby project and I've got the following model: from django.contrib.auth.models import User from django.db import models class Group(models.Model): name = models.CharField(blank=False, max_length=25) description = models.CharField(max_length=50, blank=True) user = models.ForeignKey(User, on_delete=models.CASCADE, blank=False) def __str__(self): return self.name class Meta: ordering = ('name', ) # my intention is that one user cannot have more than one group with the same name unique_together = ('name', 'user') I would like to make it possible for the user to create new groups by using this generic class based view. from django.urls import reverse_lazy from django.views import generic from groups.models import Group class GroupCreate(generic.CreateView): model = Group fields = [ 'name', 'description' ] success_url = reverse_lazy('ideas:list') template_name = 'groups/group_create.html' def form_valid(self, form): form.instance.user = self.request.user return super(GroupCreate, self).form_valid(form) As long as I don't try to make an error by sending an existing group's name, everything works fine. But if I send an existing group's name (same user!), I get the following error: IntegrityError at /groups/create UNIQUE constraint failed: groups_group.name, groups_group.user_id Why does it occur?

How do you execute a join on a foreign key in a nested for loops in Django?
I have two model classes, Part and Chapter shown below class Part(models.Model): title = models.CharField(max_length=200) # part_image = models.ImageField(upload_to=upload_location, # null=True, # blank=True, # width_field="width_field", # height_field="height_field", # verbose_name='Image',) summary = models.TextField() def __str__(self): return self.title class Chapter(models.Model): part = models.ForeignKey(Part, default=None, related_name='part', on_delete=models.CASCADE,) title = models.CharField(max_length=200) hw_link = models.CharField(max_length=200) data_link = models.CharField(max_length=200) code_link = models.CharField(max_length=200) def __str__(self): return self.title The idea is to have each part be its own section that contains the relevant chapters and links. I figured that I could do something similar to this but it isn't returning any of the chapters: {% if part_list %} {% for part in part_list %} <div class="panel panel-default"> <div class="panel-heading"><h1>{{ part.title }}</h1> <h3><small>{{ part.summary }}</small></h3> </div> <div class="panel-body"> {% for chapter in chapter_list %} {% if chapter.part == part.title %} <h3>{{ chapter.title}}</h3> <a href="{{ chapter.hw_link }}"><i class="fa fa-home" aria-hidden="true"><i class="fa fa-briefcase" aria-hidden="true"></i></i> - homework</a>&emsp;&emsp; <a href="{{ chapter.data_link }}"><i class="fa fa-shower" aria-hidden="true"></i><i class="fa fa-table" aria-hidden="true"></i> - clean data</a>&emsp;&emsp; <a href="{{ chapter.code_link }}"><i class="fa fa-free-code-camp" aria-hidden="true"></i><i class="fa fa-file-code-o" aria-hidden="true"></i> - hot code</a> {% endif%} {% endfor %} </div> </div> {% endfor %} {% else %} <p>Part is not working</p> {% endif %} -
custom user model and many to many permissions authentication and authorization django
I have a custom user model that I am building in Django. I'm pretty clear on how its going to work. I though have an interesting permisions scheme. I am trying to confrim if my thought process is correct. Each user can be part of many venues. Of each venue a user is a part of they may have a different permission. I have my user table and then I have a permissions table the permissions table is of the following: pk venueID UserID isclient isvenueviewer isvenueeventplanner isvenueadmin issuitsviewer issuitssuperuser the venue id can be null meaning that no all users will have venues attached to them. my thought is that a user first gets authenticated by the user table then that user object is checked by the permissions table for what permissions that user has. Of those permissions the one needed for the current view to be authorized is filtered through. And see if valid. am I spot on? Thank you hugs and kisses! -
Creating a checkbox in such way that a user gets updated
I am trying to create a way that a student can enroll to a teacher's course. I added a boolean field to my StudentData model and from there I added a many-to-many field to my Course model. Each of my course page is a generated slug page and there all students are listed. I want that near each student a checkbox will be shown. And if teacher selects more students and presses Enroll button, only those students can view the course. Now, the template conditionals I can do them myself, but I am stuck on updating data the right way using the checkbox. This is the boilerplate: class StudentDataForm(forms.ModelForm): enrolled = forms.BooleanField() def __init__(self): if self.checked: self.fields['enrolled'].initial = True class Meta: model = StudentData fields = ('enrolled', ) class StudentData(models.Model): name = models.CharField(max_length=30) surname = models.CharField(max_length=50) student_ID = models.CharField(unique=True, max_length=14) notes = models.CharField(max_length=255, default=None, blank=True) enrolled = models.BooleanField(default=False) course = models.ManyToManyField('Course', default=None, blank=True) class Course(models.Model): study_programme = models.ForeignKey('StudyProgramme', on_delete=models.CASCADE, default='') name = models.CharField(max_length=50, unique=True) ects = models.PositiveSmallIntegerField(validators=[MaxValueValidator(99)]) description = models.TextField() year = models.PositiveSmallIntegerField(validators=[MaxValueValidator(99)]) semester = models.IntegerField(choices=((1, "1"), (2, "2"), ), default=None) teacher1 = models.ForeignKey('TeacherData', on_delete=models.CASCADE, default=None, verbose_name="Course Teacher", related_name='%(class)s_course_teacher') teacher2 = models.ForeignKey('TeacherData', on_delete=models.CASCADE, default=None, null=True, verbose_name="Seminar Teacher", related_name='%(class)s_seminar_teacher') slug = … -

JavaScript can't access variables from Django view via HTML
The error I see in my browser console says that 2 variables in my .js throw a Reference Error because they are undefined. This code used to work but now fails as such. I have some code which somehow used to work but now fails. Since replication is very impractical, I'd like to describe the problem and learn how to better troubleshoot it. I can print the data for those variables in the context_dict from views.py and see that the data is there and everything looks OK. Those variables are called module_progressjs and studtests. I can also print the data for those variables within the HTML and see it that way. Why is JavaScript not seeing them? The HTML code to make the context_dict variables available to JS appears valid: <script type="text/javascript"> var studtests = {{ studtests | safe }}; var studobjs = {{ studobjs | safe }}; var integrityjs = {{ integrityjs | safe }}; var studsumryjs = {{ studsumryjs | safe }}; var module_progressjs = {{ module_progressjs | safe }}; var modavg = {{ modavg | safe }}; var tiiavg = {{ tiiavg | safe }}; var tii_progressjs = {{tii_progressjs | safe}}; </script> Everything else appears to be … -

Create separate scoreboard for each league in django
I'm creating a sports betting app as my first django project.

Auto Generated Admin Dashboard For Meteor.js
I was interested if the is a package which auto generates an admin dashboard for a meteor application. Something similar to the admin dashboard of django. It seems that there are two popular solutions: - https://github.com/yogiben/meteor-admin - https://github.com/gterrono/houston/ The first has a problematic package dependency, which changing it causes my app to break, and the second one is no longer maintained and also causes artifacts in the app. I am wondering if there is some other package, which I might have missed? If not, which alternative is recommended to manage users, and the app's collections? Thanks and best regards -
Serialize OneToMany relation into array in Django
Suppose I have some django models: class Restaurant(Model): name = CharField(max_length=200) class Food(Model): restaurant = ForeignKey(Restaurant, on_delete=CASCADE) name = CharField(max_length=200) One Restaurant can have multiple foods. And I want my json to look like this: [ { "name": "xxx", "food": [{"name": "xxx"}, {"name": "xxx"}, ...] }, ... ] I can use something like: restaurants = Restaurant.objects.all().values() for restaurant in restaurants: restaurant['food'] = Food.objects.filter(restaurant__id=restaurant['id']).values() But this loses some optimization in SQL level, as this is using application level loop. Is there a better way to do this?
