Querying Many To Many relationship in Django
I'm experimenting with Django and I'm trying to figure out Many to Many Relationships. Let's say I have certain model named "Facility", similarly I created another model named "Hotels" which contains fields 'facility' and 'featured_facility' both are in Many To Many relationship with "Facility". I want to add featured_facility only if it is available in 'facility' fields how can I do that? Here is my models code. class Facility(models.Model): name = models.CharField( max_length=100, validators=[validate_facility_name], unique=True, ) description = models.CharField(max_length=100, validators=[validate_facility_description]) can_be_featured = models.BooleanField(default=False) similarly Hotel model is class Hotels(models.Model): hotel_name = models.CharField( max_length=20, unique=True, validators=[validate_hotel_name] facility = models.ManyToManyField( Facility, related_name='hotel_facility', blank=True, ) featured_facility = models.ManyToManyField( Facility, related_name='featured_hotel_facility', blank=True, ) class Meta: default_permissions = () verbose_name = 'Hotel' verbose_name_plural = 'Hotels' def __str__(self): return self.hotel_name Now I want to add 'featured_facility' only if it is available in 'facility' no new featured facility from Facility can be added in 'featured_facility' I am stucked on querying many to many relationship part? -
Django, Only the view permission works, the rest of the permissions do not
First of all, I can't speak English well. test1 account permissions.py from rest_framework import permissions import copy class ViewPermissions(permissions.DjangoObjectPermissions): def __init__(self): self.perms_map = copy.deepcopy(self.perms_map) self.perms_map['GET'] = ['%(app_label)s.view_%(model_name)s'] class AddPermissions(permissions.DjangoObjectPermissions): def __init__(self): self.perms_map = copy.deepcopy(self.perms_map) self.perms_map['POST'] = ['%(app_label)s.add_%(model_name)s'] class UpdatePermissions(permissions.DjangoObjectPermissions): def __init__(self): self.perms_map = copy.deepcopy(self.perms_map) self.perms_map['PATCH'] = ['%(app_label)s.change_%(model_name)s'] view.py from rest_framework import viewsets, permissions, generics from .serializers import PlayerListSerializer from .models import PlayerList from .permission import ViewPermissions, AddPermissions, UpdatePermissions class ListPlayer(generics.ListCreateAPIView): permission_classes = [ViewPermissions, ] queryset = PlayerList.objects.all().filter(del_yn='no').order_by('-key') serializer_class = PlayerListSerializer class AddListPlayer(generics.ListCreateAPIView): permission_classes = [AddPermissions, ] queryset = PlayerList.objects.all().filter(del_yn='no').order_by('-key') serializer_class = PlayerListSerializer class DetailPlayer(generics.RetrieveUpdateDestroyAPIView): permission_classes = [UpdatePermissions, ] queryset = PlayerList.objects.all() serializer_class = PlayerListSerializer Through a simple test I confirmed that I can't see the list without 'view' permission. But for the rest of the permissions I get a '401 (Unauthorized)' error and it doesn't work. I have clearly given the authority right. Can you please let me know where the hell is the problem?

Getting all the users name who liked a post in django
I am trying to show the List of Users who Liked a Particular Post. Here is what I have tried but nothing is showing.

horizontal multiselect checkboxes in django admin
Hopefully this is a simple fix, although I haven't found anything through searching. I am using this code in admin.py to make my manytomany field appear as checkboxes in admin. class MyModelAdmin(admin.ModelAdmin): formfield_overrides = { models.ManyToManyField: {'widget': CheckboxSelectMultiple}, } But, I have about 10 choices, which is annoying as a vertical list. Is there a way to get the checkboxes to display horizontally or even more flexibly as 2 columns of five choices (or some other arbitrary look)? -
Best approach to an API update project
I'm working in a personal project to segment some data from the Sendinblue Api (CRM Service). Basically what I try to achieve is generate a new score attribute to each user base on his emailing behavior. For that proposed, the process I've plan is as follows: Get data from the API Store in database Analysis and segment the data with Python Create and update score attribute in Sendin every 24 hours The Api has a Rate limiting 400 request per minute, we are talking about 100k registers right now which means I have to spend like 3 hours to get all the initial data (currently I'm using concurrent futures to multiprocessing). After that I'll plan to store and update only the registers who present changes. I'm wondering if this is the best way to do it and which combinations of tools is better for this job. Right now I have all my script in Jupyter notebooks and I recently finished my first Django project, so I don't know if I need a django app for this one or just simple connect the notebook to a database (PostgreSQL?), and if this last one is possible which library I have to learn … -
why json response is returning nothing?

Printing out dictionary values from Python to HTML
Hey guys I'm trying to figure out how to print the values from newqueries, which I get from view.py. Why am I able to print out the values in the loop but not outside of them? What is the correct syntax to print out the username of newquery. Right now I'm getting this error when I try to print out the way below, which I know is wrong: Could not parse the remainder: '[0].username' from 'newqueries[0].username' Any ideas? view.py: def profile(request, username): userSearch = User.objects.get(username = username) userID = userSearch.id newquery = NewPost.objects.filter(username = username) followersCount = Follow.objects.filter(following_id = userID).count() return render(request, "network/profile.html", {'followers_count': followersCount, 'newqueries': newquery}) profile.html: {% extends "network/layout.html" %} {% block body %} <h2>{{user.username}}'s Profile</h2> <h1>{{newqueries[0].username}}</h1> <input type="button" value="Follow" id="followButton"> <p>Followers: <span id="followers">{{ followers_count }}</span></p> <p>Follows: </p> {% for newquery in newqueries reversed %} <div class="newpost"><p>{{ newquery.body }}</p><p>By: {{ newquery.username }} on: {{ newquery.timestamp }} Likes: {{ newquery.likes }}</p> {% endfor %} </div> {% endblock %} -
Why does sending a delete request trigger the get_queryset() Django method?
I am having trouble sending a delete request from axios to my Django backend. With axios I call delete in the following way for many of my models: // DELETE DAY export const deleteDay = (day_id) => (dispatch, getState) => { axios .delete(`/api/days/${day_id}/`, tokenConfig(getState)) ... The value of tokenConfig(getState) is just: { headers: { Authorization: "Token 032b2f569037f0125753ef8f67e7774d34a756646ae28cefd54eb1c54bd0b149" Content-type: "application/json" } } In my api.py file I have many viewsets which use my predefined model and serializer objects. The viewset that should catch this request is the DayViewSet. I followed a guide to create all of these viewsets and from what I could find online, it seems that the guide I used uses GenericAPIView functions. For this reason I've been using functions like perform_create, get_queryset, etc. I have been able to successfully call this deleteDay function, and it would just delete the instance of the object based on the day_id I gave it, but recently, after changing my get_queryset function, it seems that a strange issue has arisen. Now, when I call the deleteDay function, it calls my get_queryset function instead of whatever is normal. Here is the DayViewSet object: class DayViewSet(viewsets.ModelViewSet): permission_classes = [ permissions.IsAuthenticated ] serializer_class = DaySerializer def … -
django - combine two tables in one in views.py for using in template

Is it okay to use the same Redis store for both cache and django-channels channel layer in Django?
I have a Django 3.1 app that uses Redis for its cache backing store (django-redis). I wish to use django-channels, which has the ability to use Redis for channel layers. Is it safe or unsafe to use the same Redis store for both? In other words, I wish to have the following in my settings.py, and I want to know if that's okay. import environ env = environ.Env() REDIS_HOST = env('REDIS_HOST', default='127.0.0.1') REDIS_PORT = env('REDIS_PORT', default='6379') CACHES = { 'default': { 'BACKEND': 'django_redis.cache.RedisCache', "LOCATION": "redis://" + REDIS_HOST + ":" + REDIS_PORT + "/0", 'OPTIONS': { 'CLIENT_CLASS': 'django_redis.client.DefaultClient', 'CONNECTION_POOL_KWARGS': {'max_connections': 30}, 'IGNORE_EXCEPTIONS': True, } } } CHANNEL_LAYERS = { "default": { 'BACKEND': 'channels_redis.core.RedisChannelLayer', "CONFIG": { "hosts": [(REDIS_HOST, int(REDIS_PORT))], }, } } -
Django html table - how to specify/locate a certain cell?
new to django and everything. I'm trying to figure out how to specify or locate a certain cell in a html table. I would like to change the background color of certain cells if certain conditions are met based on the generated grid. I've registered a simple_tag, and I would like to be able to tell it which cell to change. For example, if value of row 3, column 4 == x, then apply red background; or find cell of row 2, column 5, etc. How do I address it? Here's a simplified version of what I've done so far: from views.py: list1 = [a,b,c,d,e,f] # this is basically what the table (grid) looks like list2 = [b,c,a,d,f,e] list3 = [f,a,e,d,c,b] list4 = [c,d,a,b,f,e] list5 = [d,e,b,a,f,c] list6 = [e,b,a,c,d,f] grid = [list1, list2, list3, list4, list5, list6] result1 = [0, 1, 2] result2 = [4, 5] results = [result1, result2] .html {% for var in grid %} <table> <tr> <td class='{% bg_color var.0 %}'>{{ var.0 }}</td> <td class='{% bg_color var.1 %}'>{{ var.1 }}</td> <td class='{% bg_color var.2 %}'>{{ var.2 }}</td> <td class='{% bg_color var.3 %}'>{{ var.3 }}</td> <td class='{% bg_color var.4 %}'>{{ var.4 }}</td> <td class='{% bg_color var.5 %}'>{{ … -
Design question: How would you design a temporary user table?
I am in the process of designing a website that would allow sports coaches to create teams, and then add players to that team. The goal is to allow coaches to add players to their team and associate stats to them by entering match data. The issue I'm running into is the ability for players to create their own account and link their account to one of the players the coach made. The coach would be able to enter a player account's unique ID and select a player he created on the team, and give the player access to the stats he entered for the 'fake' user. The fake user would be deleted at this point. My initial design for tackling this is as follows: I will use the default 'Users' table, and link it to a 'Profile' table via a OneToOneField. Whenever a coach creates a player for their team, a user will be created and an associated profile. The fake user would have a UUIDField as an ID in the Profile table. I'm storing the stats for players as follows: class Stats(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) match = models.ForeignKey(Match, on_delete=models.CASCADE) player = models.ForeignKey(User, on_delete=models.CASCADE) ... ... several … -

django: validate count of a many to many relation before saving to database
I'm a little bit stuck in my django project. I want to do the following: I have two models(unnecessary parts left out): models class UserGroup(models.Model): max_users = IntegerField() @property def user_count(self): return len(self.user_set.objects.all()) class User(models.Model): groups = models.ManyToManyField(UserGroup) forms class RegisterForm(ModelForm): class Meta: model = user fields = ['usergroup'] widgets = {'usergroup': CheckboxSelectMultiple()} def clean_usergroup(self): qs = self.cleaned_data['usergroup'] a = len(qs) if len(qs) > 2: raise ValidationError("Your group limit is 2") return qs The UserGroups can be defined, usually there are 3 to 5 and each UserGroup has a maximum of users that can join it. However a user is able to join multiple groups, but he should be restricted to join 2 groups at maximum. The user can choose his groups via a ModelForm which is generated from the User Model. My approach was to override the clean() method of the form and the clean_groups() of the form, but I always ran into the problem, that when the form is reloaded I get an Exception: ValueError: "<User: User object (None)>" needs to have a value for field "id" before this many-to-many relationship can be used. I know this makes sense since there isn't a saved m2m relation that can … -

Posting Base64 with Axios cause [Errno 54] Connection reset by peer
I am currently working on a web-application using VueJS for the front-end and Django (Django Rest Framework) for the back-end. One of the feature of the application is to send a pdf invoice by mail. So I was able to generate the pdf using "jspdf" library. And on Django side, I made an API end-point in order to send an email (with the pdf attached). So the logic is (tell me if it's wrong to do that): Converting the output pdf to Base64 on the front-end in order to post it to my "sendmail" endpoint with Axios. Decoding the Base64 string on the back-end, write a temp pdf file, and attached it to send the mail. It works perfectly, I tested it, the post request have a status 200. I receive the mail with the pdf attached... But on django side, I got "[Errno 54] Connection reset by peer".

Create a one to many relationship with Django
Hey guys I'm making a social media app and I have a User table with the generic User Model from Django used. I'm now creating a Follow table where I want to keep track of the different usernames the user follows and a count of those following him (I don't need to display the names for the followers field just the amount of followers a user has). How would I go about doing this? Right now this is what I have, but I'm unable to view the actual data in the database so I'm not sure how it works. Is there a column for username that is borrowed from the User model?
