Unable to show user specific link to specific page in django
I would like to create user specific links. I mean, when user signed up and logged in, he has redirected to create/ page. In that page user fills out the form and after pressing button, user has to redirect to list/ page, where there are user specific links to specific page, which contain schedule. Schedul appered from data, which user provided in create/ form. So my problem is, when I filled out the form and redirect to list/ page, there are no links.

django-autocomplete-light dependant filter over 3 models

Why Django cannot extends my form.html contact page and returns a TemplateSyntaxError or an Exception Thrown?
I'm trying to build a contact page ("/contact-us/") as a modular app instead of the similar already working contact page ("/contact/") located in the "/app/" directory. The former is failing, returning either Exception Thrown or TemplateSyntaxError while trying to {% extends %} the form.html with its base.html. My file structure: BlogDjango |-BlogDjango | | settings.py | | urls.py |-app | |-Templates | | | base.html | | | form.html |-blogpost |-contactform | |-Templates | | | base.html | | | form.html | | forms.py | | views.py settings.py TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [os.path.join(BASE_DIR, 'templates'),os.path.join(BASE_DIR,'app','templates'),os.path.join(BASE_DIR,'contactform','templates')],... base.html <!DOCTYPE html> <html> <head></head> <body> {% block content %}{% endblock %} </body></html> form.html {% extends base.html %} {% block content %} {% if title %} <h1>{{ title }}</h1> {% endif %} <form method='POST' action='.'> {% csrf_token %} {{ form.as_p }} <button type='submit'>Send</button> </form> {% endblock %} It seems that Django doesn't recognise that the base.html is located in the same directory than the form.html and therefor cannot extend it.

Does HTTP 401 response from server clears user credentials from browsers cache?
My Django 2.2 application is using basic http authentication with Apache LDAP.

How to include the thumbnail image with using TabularInline admin model?
What I am trying to do I would like to include thumbnail in PhotoInline and could be shown into ProductAdmin. What I have done I made two admin model which are ProductAdmin and PhotoInline. PhotoInline model is a separate admin model that only contains information of photos of products, which is to be connected to ProductAdmin. Inside of PhotoInline, I included custom admin function called product_thumbnail and tried to include list_display admin option of ProductAdmin. Here are my codes: class PhotoInline(admin.TabularInline): ''' PhotoAdmin Definition ''' model = models.Photo fieldsets = ( ( None, { 'fields': ('caption', 'file',) } ), ) extra = 0 and then ProductAdmin admin model looks as follows: @admin.register(models.Product) class ProductAdmin(admin.ModelAdmin): ''' ProductAdmin Definition ''' inlines = [ PhotoInline, ] list_display = ( 'product_name', 'product_price', 'product_color', 'product_size', 'product_category', 'is_onsale', 'is_newarrival', 'is_preorder', ) list_filter = ( 'is_onsale', 'is_newarrival', 'is_preorder', ) ordering = ('product_name', 'product_price', 'product_category') search_fields = [ 'product_name', 'product_category' ] Error that I got <class 'products.admin.ProductAdmin'>: (admin.E108) The value of 'list_display[8]' refers to 'product_thumbnail', which is not a callable, an attribute of 'ProductAdmin', or an attribute or method on 'products.Product'. It seems my approach is somewhat wrong. Do I need to include separate ImageField for my Product … -
Django: Simple One:Many fields aren't showing in parent object view in admin
I'm new to Django and have made a couple of classes whereby one Account can have many Subscribers. When viewing a subscriber in the django admin, it correctly shows which account the subscriber is related to. However, when looking at the account, it does not show which subscribers it has.

Django REST Framework: Use of 'pk' in get_object_or_404

Django pass input data from an HTML file to a python script and then send the final data to another HTML file
I'm trying to build a simple dictionary in Django. In the home.html file there's a form, which asks the user to enter a word.

How to send data from any customized HTML form to Django model form without using jinja {{form}} template
This is not a bug-based problem. Basically, an advice-seeking one. I am a newbie and a great fan of Django's function-based view. It allows me to customize as I need. Like I can customize the HTML form as I want. If I wish, I can also put any icons or images or any things inside my <form> </form> tag. On the other hand, the class-based view also provides lots of attractive features in CRUD operation with the jinja form template and Django's model form. So to take advantage of those features I want to use Django's model form. But as I need to customize my <form> </form> also, I need to create an HTML form also, instead of the jinja model form (bootstrap widgets based modification is not enough for it.). So how can I send data to Django's model form from my customized HTML <form>. Kindly suggest me an overall idea in which way I should approach to solve it? You can also provide me any blog or article or tutorial types of stuff. Thanks for reading the full post. -
Best way to modify the fields in response in django rest?
I have a serializer that gives this data class PostSerializer(serializers.ModelSerializer): class Meta: model = Post fields = ('id', 'name', 'cost', 'currency') class UserSerializer(serializers.ModelSerializer): posts = PostSerializer(many=True) class Meta: model = User fields = ('id', 'name') and it gives the response like this, { "id": 1, "name": "joe", "posts": [ { "id": 20, "name": "first post", "cost": 20.00, "currency": "USD" }, { "id": 21, "name": "second post", "cost": 30.00, "currency": "USD" } ] } However I want to change/add the fields of the response based on few conditions, Eg. if cost is less than 25, make it zero and add a discount field for every post. This is how I am doing. class MyPostView(APIView): def get(request): query_set = User.objects.all() user_and_posts = UserSerializer(query_set) response_data = user_and_posts.data # I am modifying the serializer data here :< for post in response_data['posts']: post['discount'] = 10 # some value if post['cost'] < 25: post['cost'] = 0 return Response(serializer.data, status=status.HTTP_200_OK) To me modifying the primitive data like this is not looking right, is there any alternate way in django rest to do this? or could've done better with serializer? In general, what's the best way to alter the response data we get from serializer and format it … -
Django Page not Loading Favicon in Chrome
I have a Django website with multiple pages, all of them load the favicon without errors on the top browsers (Chrome, Mozilla, Opera...) but recently I have noticed that in Google Chrome, the favicon in my index page isn't load, instead, I get a console error: GET http://127.0.0.1:8000/favicon.ico 404 (Not Found) (this is also happening in production) The problem with this is that I'm not making any request to /favicon.ico, instead, my code to load the icon is: <link rel="icon" href="{% static 'logo.ico' %}"> This is the same code used in the other pages and it loads fine in them, I have already tried to delete cache, delete Favicon folder in Chrome and to load the icon with full path: http://127.0.0.1:8000/static/logo.ico (if I paste this in browser I can see the icon) I don't understand why Chrome keeps making a default request to /favicon.ico instead of to the actual favicon. My Google Chrome version is: Version 91.0.4472.101 (Official Build) (64-bit) Django version is: 3.1.2 I don't think it is an issue with static files, because the favicon is loaded in other browsers, but also it is not a cache problem, do you have any suggestions about how to solve it? -
The url of the image without http is returned
I am writing a rest api application in the django rest framework in which I can post images. I want to receive the url of the image: https://path/image_name.jpg Here is my serializer class: class Serializer(serializers.ModelSerializer): url = serializers.SerializerMethodField('get_image_url') ... def get_image_url(self, obj): return obj.image.url In this case /media/filename.jpg is returned If I add the https prefix, the link will be displayed, but if I click on it I get an error: browser can not connect to the server localhost
