How to import values from database into a OptionMenu Django Python
I have a models page here. from django.db import models class Trainee(models.Model): TraineeID = models.AutoField(primary_key=True) Name = models.CharField(max_length=50) Course = models.CharField(max_length=20) BatchNo = models.CharField(max_length=15) DateofBirth = models.CharField(max_length=30) ContactNo = models.CharField(max_length=20) ContactAddress = models.CharField(max_length=80) EmailAddress = models.EmailField() class Meta(): db_table = "Trainee" class Course(models.Model): CourseID = models.AutoField(primary_key=True) CourseName = models.CharField(max_length=20) CourseDuration = models.CharField(max_length=30) CourseCost = models.CharField(max_length=50) class Meta(): db_table = "Courses" I made a html page where I can enter data and save Trainee. I want to make it so that Course will be a OptionMenu not a charfield that will have the options <select> only from the data saved in Courses table. So if there are saved data's like-Java, Python, C etc in Courses table then the option menu Course will only have these on it. And if they are deleted or new ones are added then the optionmenu will change accordingly. This is my html page where I can enter the data and save it: {% extends "MyTestApp/base.html" %} {% block body_block %} {% load static %} <link rel="stylesheet" href="{% static '/css/bootstrap.min.css'%}" /> <form method="post" action="/trainee/"> {%csrf_token%} <div class="container"> <br/> <div class="form-group row"> <label class="col-sm-1 col-form-label"></label> <div class="col-sm-4"> <h3> Enter Trainee Information </h3> </div> </div> <div class="form-group row"> <label … -
django relation between classes
Let say you have a class Project that is own by a team. One team can have many projects, but only one team for each project. class Project(models.Model): project_manager = models.ForeignKey(Profile, on_delete=CASCADE) title = models.CharField(max_length=55, null=True, blank=True) developers = models.ManyToManyField(Profile, related_name='projects') slug = models.SlugField(max_length=500, unique=True, blank=True) description = models.TextField(default="Project description") teams = models.ForeignKey(Team, blank=True, null=True, on_delete=CASCADE) Then each project has a task, so have to create a task class with a foregin key to project class Task(models.Model): title = models.CharField(max_length=55, null=True, blank=True) members = models.ManyToManyField(Profile, related_name='tasks') slug = models.SlugField(max_length=500, unique=True, blank=True) task_completed = models.BooleanField(default=False) description = models.TextField(default="Task description") project = models.ForeignKey(Project, blank=True, null=True, on_delete=CASCADE) when then trying to get all the members from the task class, while being in a view for the project class, there is no relation, project does not have access, how do one make sure project knows of Tasks as Tasks knows of project? -

How to put Excel data in multiple model columns in django.?
I'm developing a shopping mall integrated management site. There is a lot of order data in one Excel file, and the data in each row of order data contains the data required for each model, so the reason the model is separated is because it has been normalized. Anyway, I want to put the data in this Excel in the field of each model. Is there a way? And I will receive the Excel file from the template through form. There are three models, and I want to insert data from one Excel file into the fields of each model.? models.py 배송요금정산코드 = ( ('정산완료','정산완료'), ('미정산','미정산'), ('취소/차감','취소/차감'), ) '''배송관리 모델''' class DEL(models.Model): del_no = models.CharField(db_column='DEL_NO', max_length=17, primary_key=True) # Field name made lowercase. ord_no = models.ForeignKey('ORD', models.DO_NOTHING, db_column='ORD_NO' ,related_name='ORD_NO_DEL',verbose_name='주문번호') # Field name made lowercase. del_wy_cd = models.CharField(db_column='DEL_WY_CD', max_length=19,verbose_name='배송방법코드') # Field name made lowercase. del_co = models.CharField(db_column='DEL_CO', max_length=20, blank=True, null=True,verbose_name='택배사') # Field name made lowercase. wb_no = models.CharField(db_column='WB_NO', unique=True, max_length=14, blank=True, null=True,verbose_name='송장번호') # Field name made lowercase. wb_dttm = models.DateTimeField(db_column='WB_DTTM', blank=True, null=True,verbose_name='송장입력일시') # Field name made lowercase. to_nm = models.CharField(db_column='TO_NM', max_length=100,verbose_name='수취인명') # Field name made lowercase. to_tel1 = models.CharField(db_column='TO_TEL1', max_length=12,verbose_name='수취인 연락처1') # Field name made lowercase. to_tel2 = models.CharField(db_column='TO_TEL2', max_length=45, blank=True, null=True,verbose_name='수취인 … -
Django find average number of followers
I have a model: class User(models.Model): followers = models.ManyToMany('users.User', related_name='following') # Other non important fields... From this I want to find BOTH: the average number of followers a user has the average number of users a user is following I have tried these respectively: User.objects.aggregate(Avg('followers'))['followers__avg'] User.objects.aggregate(Avg('following'))['following__avg'] But they are not pulling up the correct data. For example for (1) I have 3 users, one of them follows the other 2 and one of the other 2 follows the first. My code above gives 1.3333, which is not correct, it should be 1 as each there are 3 followers total (even though the first user follows 2 users he should count as 2x followers) Let me know if you need anymore examples. Thanks in advance. -
Use Django Auth User for frontent Firebase authentification
I'm using Django as my Backend REST API with MongoDB and React in my Frontend. My goal is to work with multiple Databases. MongoDB (handled over Django) and Firebase (mostly handled in Frontend over React in JSX). Currently, all my users and authentification is happening in Django with MongoDB and I want to use the already existing working user accounts to log into Firebase in the Frontend if they are logged in in Django. I found multiple resources but nearly all of them have the users and auth happening in Firebase and I need it the opposite way. My users are in Django so I need some kind of creds or auth that will be forwarded to the frontend and logged the user automatically into firebase if they're logged in into Django. I hope anyone can help me out I'm lost here been reading a lot of resources but none was matching this request. -
Django : How to position the content next to the sidebar and below a navbar
I am a newbee in Django, CSS, JS. I'm using the Sidebar and NavBar Templates from the Bootstrap and I would like to add the content of the page next to the sidebar and below the navbar. Like I saw in few tutorials, I split the html script of the sidebar and navbar, and call them in the main.html. I want to do an app where I upload files.

Django iterate over list, return seperate items in template
I'm new to django, so the solution I'm looking for is possibly very basic. However, I read what I could find about list iteration in templates, but I still can't seem to get it right. I'm working on a search function that takes a query and compares it to a list of entries ('entries'). If the query is a substring of one of the entries in the list, I want to add that entry to a list ('results'). Then, I want to print the items in the list 'results' from a template. def search(request): query = request.POST["q"] if util.get_entry(query) == None: results = ["foo", "baz"], entries = util.list_entries(), for entry in entries: if query in entry: results.append(entry) return render(request, "encyclopedia/search.html", { "title": query, "results": results, "entries": entries }) and the template: <ul> {% for result in results %} <li>{{ result }}</li> {% endfor %} </ul> <h3>For testing purposes:</h3> <ul> {% for entry in entries %} <li>{{ entry }}</li> {% endfor %} </ul> However, I can't get it to work. For testing purposes, I first tried printing the list of entries from the template. But in stead of printing the separate entries, it seems to print the full list: ['foo', 'baz'] … -
GeoDjango rendering same geometry multiple times in leaflet map
I have a GeoDjango app following this tutorial but substituting World Borders polygon data as included in the standard GeoDjango tutorial. I have created serializers and a django rest api that displays geometry intersecting the current bounding box using leaflet. The problem I've noticed is that when I pan around the map, it renders duplicate polygons on top of each other each time I set a new bounding box extent request. This results in the map slowing down as the number of polygons increases and also results in an opaque symbology. How do I ensure each polygon only renders once and not each time the map location refreshes? models.py from django.contrib.gis.db import models class WorldBorder(models.Model): # Regular Django fields corresponding to the attributes in the # world borders shapefile. name = models.CharField(max_length=50) area = models.IntegerField() pop2005 = models.IntegerField('Population 2005') fips = models.CharField('FIPS Code', max_length=2, null=True) iso2 = models.CharField('2 Digit ISO', max_length=2) iso3 = models.CharField('3 Digit ISO', max_length=3) un = models.IntegerField('United Nations Code') region = models.IntegerField('Region Code') subregion = models.IntegerField('Sub-Region Code') lon = models.FloatField() lat = models.FloatField() # GeoDjango-specific: a geometry field (MultiPolygonField) mpoly = models.MultiPolygonField() # Returns the string representation of the model. def __str__(self): return self.name class Meta: ordering … -
Django DeserializedObject update
I have a dynamically loaded object from a json file. As per documentation, I can save the object in this way: for deserialized_object in serializers.deserialize("json", data): if object_should_be_saved(deserialized_object): deserialized_object.save() However, if the object already exists in the datadatabase, I quite rightly get the django.db.utils.IntegrityError: duplicate key value violates unique constraint . I can't see anything in the docs that would allow to do a deserialized_object.update() instead of a deserialized_object.save(). Is that possible? -
Wagtail embedding images with HTML
We use StreamField to allow editors to add HTML for custom layouts. We used to be able include images in by looking up the ID of the Image and an embed code: <embed alt="My Image" embedtype="image" format="responsive" id="3896"/> Since performing an update to Wagtail these do not render. I'm wondering if this was an unintended feature which has been removed or if something about this code has changed. -

How to find which channel sent a particular message in Django channels + Websocket api?
I am implementing a broadcaster using Django channels i.e, i am implementing a group of channels where a message sent from a single consumer instance associated with a channel will be sent to all other instances that have their associated channels registered in that group.

Django url not cannot find some UTF-8 usernames
i am experimenting with UTF-8 for usernames in a django app. Django is Version 3.2.11 Python used is 3.9.4 Some users might have a profile visible to others and ther username in the url: re_path("^u/(?P<username>\w+)/$", views.author_profile_view, name="author_profile_view"), Normal Example works fine: Browser shows -> /u/brainyChowder3/ Django shows -> GET /u/brainyChowder3/ HTTP/1.1" 200 10593 UTF-8 example 1 works also fine: Browser shows -> /u/ɊȁⱲÒđΈⱦİĬd/ Django shows -> GET /u/%C9%8A%C8%81%E2%B1%B2%C3%92%C4%91%CE%88%E2%B1%A6%C4%B0%C4%ACd/ HTTP/1.1" 200 12508 But this UTF-8 does not work: Browser shows -> /u/ɂáⱳ1⁄4%7Cĭğę Django shows -> "GET /u/%C9%82%C3%A1%E2%B1%B31%E2%81%844%7C%C4%AD%C4%9F%C4%99 HTTP/1.1" 404 5585 The browser does show it strange, as he does not "translate" %7C to |, but that should be just optical?

In Django shell I can query this user: >>> User.objects.get(username='ɂáⱳ1⁄4|ĭğę') <User: ɂáⱳ1⁄4|ĭğę> The URI decoding looks ok to me. I hope someone can explain why this is happening to one UTF-8 string, but not the other.

How do I pass Django local variable of a funtion in views to javascript fetch API?
