Alert from HTML script in Django
I am prying to display alert in my Django project. I am passing values from views.py to singup.html to display alert based on condition. But initially my alert variable in HTML doesn't get value. Only after clicking on Submit button alert is initialized and displays the required alert. Views.py def signup(request): d = {} data={} template={} context={} print(request.POST) if request.method == 'POST': form = RegisterForm1(request.POST) print("hello212") if request.POST.get('email1') and request.POST.get('password1'): post = Register1() post.email = request.POST.get('email1') post.password = request.POST.get('password1') post.repeatpassword=request.POST.get('repeatpassword1') print(post.email) print(post.password) print(post.repeatpassword) data=Register.objects.filter(email__iexact=post.email).exists() print (data) if post.password == post.repeatpassword: if data == False: post.save() alert = 0 print("check") else: alert = 2 context={ "alert":alert, } print (context) # template= "personal_anshul/signup.html" return render(request, "personal_anshul/signup.html", context) Signup: <input type="hidden" name="alert" value="{{alert}}" readonly> <script> function check() { <!--{% for message in messages %}--> <!--<div class="alert alert-{{ message.tags }}">{{ message }}</div>--> <!--{% endfor %}--> <!--alert("check")--> console.log({{ alert }}) if ({{alert}} == 2) { alert("id exists") } else{ alert("You Genius!") } } </script> Alert value when i go to my page for the first time: enter image description here Alert value after i click on submit button: enter image description here How to initialize alert so that i get a value to compare my ... -
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}}"> -

Django doesn't render 404 page when passing to nginx
I want to show Django custom 404 page by nginx when passing url not exists. But It seems like the nginx simply show the 404 page without Django rendering. How could I fix it. Here are my Django and nginx setting. In myblog/urls.py urls.py handler404 = 'views.handler404' In myblog/views.py views.py def handler404(requests): return render(requests, '404.html', status=404) In templates/404.html templates/404.html {% extends "base.html" %} {% block content %} {# some 404 content #} {% endblock %} In nginx.conf nginx.conf location /404.html { alias /my/path/templates/404.html; } error_page 404 500 403 /404.html; uwsgi_intercept_errors on; And the 404 page show like this: (it's a sample) 404.page Thank you very much.
