Best way to code and to connect two models in python
I have created a "quote" app and in my next phase I would like to create a dropdown list with my "contacts". I'm only wondering what is the easiest, and best practices to create another class with the details of the contacts, or creating a new "app" to hold all the details of the contacts. -

Whenever I try to run python manage.py runserver and go to the admin site, I lose connection to the server immediately. The API Root page works fine it is just the admin page.

Django datefield default save format overwriting
I have a postgresql9.6 table which has a char field: 'start_date', and the format like '20200101'. And I created a Django2.0 model: class TestModel(models.Model): start_date = models.DateField('start_date') My admin.py is: class TestAdmin(admin.ModelAdmin): list_display = ('start_date',) admin.site.register(TestModel, TestAdmin) And I also modify settings.py: USE_L10N = False DATE_INPUT_FORMATS = ['%Y%m%d'] DATE_FORMATS = ['%Y%m%d'] So I get the date in web form:'20200101', but when I save the form, shows a error: 'value has an invalid date format. It must be " "in YYYY-MM-DD format.' I know the DateField save the date default use 'YYYY-MM-DD' format, but I need to change it to 'YYYYMMDD' so I can save the consistent data into pg database. So how to overwriting the DateField or Model function to change the default format? -

How do I properly link my CommentCreateView to my post_detail view?
I have two models, Post and Comment. My Comment model contains the model Post as a foreign key, which matches each comment to a particular post. I have two views: a post_detail view where I can see a post, and a CommentCreateView to create a comment. I created a comment_new.html template that contains the CommentCreateView form, and included the comment_new.html template into my post_detail.html template. However, the actual form to post the comment in doesn't show up, only the 'Post' button does. Here is a snippet of the template and the HTML rendered. post_detail.html {% include 'comment_new.html' %} comment_new.html <form action="" method="post"> {% csrf_token %} {{ form.as_p }} <button type="submit">Post</button> </form> HTML Rendered: I think the problem is that the CommentCreateView does not know what Post to be linked to, but I'm not certain, so if you have any suggestions, I'm definitely open to any. My question is, I'm not sure how I can get the primary key of the post, and send the data to the CommentCreateView form so that the comment knows which post it needs to be in. Here are the relevant snippets of my code, below. Thank you! Models.py: class Comment(models.Model): post = models.ForeignKey(Post, on_delete=models.CASCADE, related_name='comments') … -
Style for a selectbox CSS and HTML
Somebody just helped me to remove the outline of my selectbox (from my first bootstrap-django project) Now, i wanted to ask for your help to change the border color property of the options box itself, which is blue, and i'm trying to make it yellow. Also, for some reason when the select box has the default value, its border is yellow but after you select one of the options, it becomes darker, and i would like it to be darker from the beggining. Here is my CSS: .selector{ outline:none; position:absolute; border-radius:1rem; margin-left:260px; width:500px; border-color: #C9C9C9; height:35px; font-size: 15px; text-align-last: center; color:#C9C9C9; } .selector:focus{ border-color:#FFD700; box-shadow: 0 0 8px #FFD700; } And my HTML: <div class="div1"> <label for="estado" class="label1"> Estado <select class="selector" id="estado" name="estado" onchange="functionfs()" style="border-color: #C9C9C9; "> <option style="color:black" selected="selected" value="-----">--- Ingrese un valor ---</option> <option value="Activo" style="color:black;">Activo</option> <option value="Inactivo" style="color:black;">Inactivo</option> </select> </label> </div> And my JS: <script type="text/javascript"> var selector = document.getElementById("estado"); function functionfs(valor){ selector.setAttribute("style", "color:black;"); } </script> I will also attach 2 images of the problem itself. As you can see, when i select one of the two states and click it again, it becomes darker. Thanks everyone! -
Change a set to a dictionary - Django Python
I am trying to combine these two views. This is what I have. MenuView is to combine with add_to_menu so that if the if statement returns negative, the menuview portion still runs and displays the menu on my html page. If the if the statement is positive, it still shows the menu, but also adds the entered information into the database. I can only get one or the other to work at a time. When I run this, I get an error telling me it has to be a dictionary and not a set. Views.py: class MenuView(ListView): model = Product template_name = 'mis446/edit-menu.html' context_object_name = 'show_menu' def add_to_menu(request): if request.method == 'POST': if request.POST.get('name') and request.POST.get('price') and request.POST.get('nickname'): post=Product() post.name= request.POST.get('name') post.price= request.POST.get('price') post.slug= request.POST.get('nickname') post.save() model = Product context_object_name = {'show_menu'} return render(request, 'mis446/edit-menu.html', context_object_name) else: model = Product context_object_name = {'show_menu'} return render(request,'mis446/edit-menu.html') -
Django management command not capturing command line arguments
I am trying to run a Django management command with some optional arguments. The relevant code is below. def add_arguments(self, parser): parser.add_argument('--from-date', type=str, help='Some help text') parser.add_argument('--to-date', type=str, help='Some help text') parser.add_argument('--from-type', type=str, help='Some help text') parser.add_argument('--until-type', type=str, help='Some help text') def handle(self, *args, **options): from_date = options.get('from-date') to_date = options.get('to-date') from_type = options.get('from-type') until_type = options.get('until-type') When I try to run the command in the terminal as follows, the arguments aren't being picked up. python manage.py [NAME OF COMMAND] --from-date 2020-04-02 --to-date 2020-04-03 Why is this?

creating a related field, when initiating user, in Django
I have a model like this: class CustomUser(AbstractUser): history = models.TextField(verbose_name="History", max_length=500,default='-') def save(self, **kwargs): super(CustomUser, self).save(**kwargs) self.apayment4thisuser.create(catagory="trial",paid=0,paymenttoken="#") So the idea is to create a default related payment model (apayment4thisuser), when a user is created. This works fine,but the problem is that it will run Save() whenever the user is updates too(obviously). However I need this to be run just once. i.e., only when user signs up and created in the database for the first time. I don't need it when an existing user is updated. What would be the best way to achieve this? Thanks, -
How to amend the default starting script for Django Console in Pycharm
The starting script defaults to the following every time I start a new project. import sys; print('Python %s on %s' % (sys.version, sys.platform)) import django; print('Django %s' % django.get_version()) import os os.environ.setdefault("DATABASE_URL","postgres://{}:{}@{}:{}/{}".format(os.environ['POSTGRES_USER'], os.environ['POSTGRES_PASSWORD'], os.environ['POSTGRES_HOST'], os.environ['POSTGRES_PORT'], os.environ['POSTGRES_DB'])) sys.path.extend([WORKING_DIR_AND_PYTHON_PATHS]) if 'setup' in dir(django): django.setup() import django_manage_shell; django_manage_shell.run(PROJECT_ROOT) Is there a way to change this default script? I've tried to do so under File>Default Settings, but there is only Python console listed here; Django console isn't listed. -
Getting this error: argparse.ArgumentError: argument -d/--to-date: conflicting option string: -d
I am writing a Django management command. I would like to include optional arguments.

Selectbox border color

I'm trying to style it so when you click on it its border and the options box border turns yellow, and that's working fine, but there is also a blue rectangle around my selectbox when i click on it that i don't really want.

Self-referencing foreign keys are listing everything if the value is null in Django-admin Page
I have a django model as below: class Words(models.Model): bare = models.CharField(max_length=100) accented = models.CharField(max_length=100) derived_from_word = models.ForeignKey('self', models.DO_NOTHING, blank=True, null=True, related_name='derived_words', related_query_name='derived_word') There is a field derived_from_word which shows that some of the words are derived from some other word. If it is not derived from any word so the field value is NULL. What issue i am having that when i register this model in the django-admin and when i opened any of the word for editing, the derived_from_word field is listing all the words and i can not find a way for it to list only the derived word or the NULL value. Due to high load of the words the drop down list is making the page unresponsive. -

HTML Video tag not finding file

Or not because it's located in a model? video_output.html {% extends 'highlights/base.html' %} {% block content %} {% for video in highlights %} <video width="320" height="240" controls> <source src="/media/{{ video.highlight }}" type="video/mp4"> Your browser does not support the video tag </video> {% endfor %} {% endblock %} From views.py def video_output(request): entrydata = Video.objects.last() context = { 'highlights' : Highlight.objects.filter(sourcevideo=entrydata.video_id) } return render(request, 'highlights/video_output.html', context) Console output [04/Apr/2020 11:32:13] "GET /highlights/outputs HTTP/1.1" 200 1960 Not Found: /media/highlights/812.mp4 Not Found: /media/highlights/811.mp4 [04/Apr/2020 11:32:14] "GET /media/highlights/812.mp4 HTTP/1.1" 404 2129 [04/Apr/2020 11:32:14] "GET /media/highlights/811.mp4 HTTP/1.1" 404 2129 Not Found: /media/highlights/814.mp4 Not Found: /media/highlights/813.mp4 [04/Apr/2020 11:32:14] "GET /media/highlights/814.mp4 HTTP/1.1" 404 2129 [04/Apr/2020 11:32:14] "GET /media/highlights/813.mp4 HTTP/1.1" 404 2129 Not Found: /media/highlights/815.mp4 Not Found: /media/highlights/816.mp4 [04/Apr/2020 11:32:14] "GET /media/highlights/815.mp4 HTTP/1.1" 404 2129 [04/Apr/2020 11:32:14] "GET /media/highlights/816.mp4 HTTP/1.1" 404 2129 Not Found: /media/highlights/817.mp4 [04/Apr/2020 …
