Django foreign relations regarding form and multiple file upload
i have a Patient model, which can contain many files uploaded by the staff ( test results of all sorts ) , what happens is that the form for adding a new patient and uploading files to that patient cannot go through because the file feed is initially empty, but it cannot be empty.. here is the code //models.py class Patient(models.Model): name = models.CharField(max_length=200, blank=True) created_at = models.DateTimeField(auto_now=True) tests = models.CharField(max_length=200,blank=True) feed = models.ForeignKey('Feed', on_delete=models.CASCADE, blank=True) def __str__(self): return self.name class FeedFile(models.Model): files = models.FileField(upload_to="documents/%Y/%m/%d") def __str__(self): return self.files class Feed(models.Model): name = 'files' files=models.ManyToManyField(FeedFile, blank=True) def __str__(self): return self.name //views.py class PatientCreate(CreateView): model = Patient fields = ['name'] //forms.py class NewPatientForm(ModelForm): files = forms.FileField(widget=forms.ClearableFileInput(attrs={'multiple': True})) class Meta: model = Patient fields = '__all__' def __init__(self, *args, **kwargs): super(NewPatientForm, self).__init__(*args, **kwargs) self.fields['feed'].required = False as you can see in the last part i have even tried to define that the feed field can be empty, but still when filling out the new patient form it wont go through ( " this field is required") Thanks. -

ImportError: cannot import name 'Employee'
First, let me start by letting you know that I'm creating a time attendance and payroll software. I have multiple models with Employee at the center of the entire architecture. Different apps have different models each storing different kind of settings(LeaveSettings, ShiftSetttings, etc ). These models are a foreign key in the Employee model. I also have some hidden models to store arbitrary data like Balances, etc. Employee is also imported and used as a foreign key in all of these models. Eg: LeaveSettings and LeaveBalance are in an app called leavemanagement. Employee imports LeaveSettings and has a LeaveSettings Foreign Key LeaveBalance imports Employee and uses it as a foreign key. This is the error i get: File "E:\OnTime\mysite\leavemanagement\models\__init__.py", line 4, in <module> from leavemanagement.models.model_leavebalance import LeaveBalance File "E:\OnTime\mysite\leavemanagement\models\model_leavebalance.py", line 3, in <module> from master.models.model_employee import Employee File "E:\OnTime\mysite\master\models\__init__.py", line 4, in <module> from master.models.model_employee import Employee File "E:\OnTime\mysite\master\models\model_employee.py", line 9, in <module> from payroll.models.model_months import Months File "E:\OnTime\mysite\payroll\models\__init__.py", line 6, in <module> from payroll.models.model_reimbursmentdetail import Reimbursement File "E:\OnTime\mysite\payroll\models\model_reimbursmentdetail.py", line 1, in <module> from master.models.model_employee import Employee ImportError: cannot import name 'Employee' -

Django template image.path.url does not work
I have a model with an ImageField called photo, but the html template gets an empty string when I use photo.path.url. This is the model: class Photograph(models.Model): owner = models.ForeignKey(User, on_delete=models.PROTECT, related_name='photos_of_user') photo = models.ImageField() album = models.ForeignKey('Album', on_delete=models.CASCADE, related_name='photos_of_album') description = models.CharField(max_length=256) def __str__(self): return self.description This function returns the context I send to the template: def populate_with_album_content(self, album_pk): album = Album.objects.get(id=album_pk) photos = album.photos_of_album.all() return { 'album': album, 'photos': photos } And this is the html template: {% for photo in photos %} <div class="col-md-55"> <div class="thumbnail"> <div class="image view view-first"> <img style="width: 100%; display: block;" src="{{photo.photo.path.url}}" alt="image" /> <div class="mask"> <p>Your Text</p> <div class="tools tools-bottom"> <a href="#"><i class="fa fa-link"></i></a> <a href="#"><i class="fa fa-pencil"></i></a> <a href="#"><i class="fa fa-times"></i></a> </div> </div> </div> <div class="caption"> <p>{{ photo.description }}</p> </div> </div> </div> {% endfor %} I know urls are well configured because I can see the pictures in the admin page, but, when I view the resulting page source, I can see that src are equal to empty strings. -
Albums dont show information
I'm watching a tutorial on Django and I've been following along but I've noticed small differences between my Django and his, this all might be because I have the current patch and he has the 2016 version. The problem is that I've been trying to focus on the music app of the project. But whenever I create details of the album such as artist, album_name, genre I then save them in the shell. To then check I reopen the shell and type Album.objects.all() and get four unspecified objects. <QuerySet [<Album: Album object (1)>, <Album: Album object (2)>, <Album: Album object (3)>, <Album: Album object (4)>]> I wrote this line in the models.py file to no avail from django.db import models # RED pk 1 class Album(models.Model): artist = models.CharField(max_length=100) album_title = models.CharField(max_length=250) genre = models.CharField(max_length=50) album_logo = models.CharField(max_length=1000) def __str__(self): return self.album_title + ' - ' + self.artist # RED fk 1 class Song(models.Model): album = models.ForeignKey(Album, on_delete=models.CASCADE) file_type = models.CharField(max_length=10) song_title = models.CharField(max_length=250) -

Django how to GET value from template table?
I am trying to use values in a table that has been populated from a queryset to load their associated objects in a modal. Here is a snippet of the code that populates the table: {% for rec in accounts %} <tr> <td class="text-center"> <input type="button" data-toggle="modal" href="#accountModal" class="document-link btn btn-primary" value="{{rec.subscriber_fields.internal_id}}" > </td> <td>{{rec.accname}}</td> <td>{{rec.subscriber_fields.custom_1}}</td> <td>{{rec.acc_county}}</td> <td>{{rec.acc_state}}</td> <td>{{rec.subscriber_fields.custom_2}}</td> <td>{{rec.uploaded_on}}</td> </tr> {%endfor%} What I'm hoping to achieve is: click on the button and pass interna_id to the views.py use internal_id to get the object it's associated with instantiate the form in the modal with the object's info to edit How can this be done? It took me a while to realize that I can't GET/POST from a table like I would a form so I'm really stuck. I'm using function based views. TIA -

Toggle javascript debug in Django template
I am working on the javascript side of a Django project and my javascript functions output some text to the console so that I can debug more easily. My javascript files look like the following: (function(nameSpace, $, undefined ) { var debug = true; nameSpace.foo = function() { if (debug) { console.log('foo was there') } }; }(window.nameSpace = window.nameSpace || {}, jQuery )); I thought that it would be preferable to toggle off this output in production but I don't want to change each javascript file. So I thought I would create a context_processor to pass the value of settings.DEBUG to my base template. Now I have in my base.html: <html> <head> ... <script> var debug = {{ DEBUG }}; </script> </head> ... </html> and my javascript files have var debug = window.debug instead of a hardcoded boolean. Looking back into this I am wondering if this is safe. I presume someone could easily temper with the window.debug variable, which is fine as long as the console output doesn't leak security information like csrf tokens for example. I am not a security expert but I feel something a bit slippery here. Is my current idea safe? And if not how … -

Why to use {%url ....%} with slug?
I'm new in Django and making a simple blog to improve my skills. I couldn't understand the purpose of using {% url XXX %} with slug.More precisely; <a href ="{% url 'theview' post.slug%}"> As i know, url tag above will map the link to view function named 'theview'. And also there is a regular expression filter on url.py to catch clicked link and match it to the appropriate view function. Then why we use {%url%} although there is a filter to notice if the link is slug or not? Isn't it enough to create link like; <a href="{{post.slug}}"> -

Reject POST request if particular columns are not unique
How can I prevent a POST request from being saved if the following items: 'email', 'youtube_channel_username', 'youtube_channel_url', 'youtube_channel_title' already exist in the database? In effect, I want to add a validation step that ensures that what the user is trying to post is unique for the above-mentioned. Ideally the server should send back an error message to the user informing them that their request failed for whatsoever reason. Here is my code so far. I am not sure where to add this feature, so I would appreciate some help! serializers.py class CreatorSignupSerializer(serializers.Serializer): """ Create Creator profile """ first_name = serializers.CharField(required=True, write_only=True) last_name = serializers.CharField(required=True, write_only=True) email = serializers.CharField(required=True, write_only=True) youtube_channel_username = serializers.CharField(required=True, write_only=True) youtube_channel_url = serializers.CharField(required=True, write_only=True) youtube_channel_title = serializers.CharField(required=True, write_only=True) youtube_channel_description = serializers.CharField(required=True, write_only=True) photo = serializers.CharField(required=True, write_only=True) youtube_channel_start_date = serializers.CharField(required=True, write_only=True) keywords = serializers.CharField(required=True, write_only=True) no_of_subscribers = serializers.IntegerField(required=True, write_only=True) no_of_videos = serializers.IntegerField(required=True, write_only=True) no_of_views = serializers.IntegerField(required=True, write_only=True) no_of_likes = serializers.IntegerField(required=True, write_only=True) no_of_dislikes = serializers.IntegerField(required=True, write_only=True) location = serializers.CharField(required=True, write_only=True) avg_views = serializers.IntegerField(required=True, write_only=True) gender = serializers.IntegerField(required=True, write_only=True) password = serializers.CharField(required=True, write_only=True) class Meta: model = Creator fields = ( 'first_name', 'last_name', 'email', 'youtube_channel_username', 'youtube_channel_url', 'youtube_channel_title', 'youtube_channel_description', 'photo', 'youtube_channel_start_date', 'keywords', 'no_of_subscribers', 'no_of_videos', 'no_of_views', 'no_of_dislikes', 'no_of_likes' 'location', 'avg_views', 'gender', 'password', …
