Should I list the contestants according to the selected division?
I'm new to web development and I use the Django framework! I ask you to help or guide me on the right path. It is necessary to implement a selection of contestants according to the division selected from the drop-down list. The contestant model has a secondary key to the division model, the template implements the output of two forms: class divisionForm(ModelForm): # Подразделения class Meta: model = division fields = ['name_division'] widgets = { "name_division": Select(attrs={}), } class contestantForm(ModelForm): # Конкурсанты class Meta: model = contestant fields = ['name_contestant'] widgets = { "name_contestant": Select(attrs={}), } enter image description here As far as I understand, Django acts as a server and when the page loads, it returns the data processed in views.py how to implement the withdrawal of all contestants from the selected division in the template? already on the client side without POST and GET requests. Do you have a javascript example for interacting with Django on a similar topic? -
Concatenate 2 RawQuerySets Django
so i have each entity their and they are from legacy system, thats why i cannot perform migration. For example : Entity1 Blog Entity1 Entry Entity2 Blog Entity2 Entry There are 9 entities, means 18 tables So here is my view.py but i cannot do entity1_data.union(entity2_data). How can i merge these, so i can present it in 1 table? Ps: i would try union SQL, but theres too long. entity1_data = BlogModel.objects.using("bcdb").raw("SELECT blog.id as id, blog.name," + "entry.title, " + "entry.date " + "FROM [Entity1 Blog] as blog " + "INNER JOIN [Entity1 Entry] as entry " + "on blog.id = entry.blog_id") entity2_data = BlogModel.objects.using("bcdb").raw("SELECT blog.id as id, blog.name," + "entry.title, " + "entry.date " + "FROM [Entity2 Blog] as blog " + "INNER JOIN [Entity2 Entry] as entry " + "on blog.id = entry.blog_id") I hope i can do it dynamically using dict of tables name. Merged table | Blog ID | Blog Name | Entry Title | Entry Date | | ------------------ | -------------------- | ---------------------- | --------------------- | | [Entity 1 Blog].ID | [Entity 1 Blog].name | [Entity 1 Entry].title | [Entity 1 Entry].date | | [Entity 2 Blog].ID | [Entity 2 Blog].name | [Entity 2 Entry].title … -
Question about using Group or Role in frontend application to restrict view
I am building an application that comprises a python backend using the django framework and a vue application on the frontend. I am using with success the authorization and permissions framework provided by django. I have created groups that possess a set of permissions and I have assigned users to them. Technically, after reading the docs, it is recommended to use groups to check for permissions and not roles. A problem arises when I need to serialize the user and send it to the frontend. What kind of information should I send to determine permissions on the frontend? Should I serialize all the groups the user belongs to with the respective permissions, or should I create a role field in my database to simplify things out (the roles are quite well defined) and just send that. What is the common solution or what would be reasonable? What kind of questions should be answered when approaching this problem? Thank you for your time. -
while we want to develop a travelling website using react how can we integrate a map api into our project
we need to provide a route map just like the google maps based on the user input that he/she wanted to visit the place, that should display the starting and destination locations of the user along with the type of transport that is available to visit that place. we tried to integrate the google maps API by generating a token but we are unable to integrate it in our project and we suppose that it is also not free of cost.so we need a map API and the process to integrate the API that can take the user input(location that the user wanted to visit). -

How do I efficiently evaluate and exclude certain values from a Django queryset?

Show 'is_staff' as False in Django template
I am writing a front end admin portal to allow for admins to manage users from a front end perspective. I am trying to get a 'user status' table set up so that admins can get the users current status. I am using the is_staff and is_active within the auth_users table to get the users status.

I have a problem merging navigation bar and footer html file together in my base html
I've been trying to figure out how to include the two templates in my base html and I found no success. I'm not certainly familiar with {% include %} and {% extends %} function and I believe I am not using it correctly to fix problem. With that being said, I added my navigation bar html using {% include %} on my base html along with my footer html also using with {% include %} as shown. The result is only the footer html appeared meanwhile the navigation bar html only resulted to a horizontal line beneath the search bar. {% load static %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>home</title> <link rel="stylesheet" href="/static/css/homestyle.css"> </head> <body> {% include 'webapp/templates/pages/navbar.html' %} <!-- navigation bar html --> {% include 'webapp/templates/pages/footer.html' %} <!-- footer html--> </body> </html> <!--navigation bar html --> {% load static %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>navbar</title> <link rel="stylesheet" href="/static/css/navbar.css">` ` </head> <body> <nav class="login_nav"> <p> login </p> </nav> <hr class="solid"> <nav> <img src="/static/images/user_logo.png"> <ul class="nav_links"> <li><a href="http://127.0.0.1:8000/artists/"> apple </a></li> <li><a href="http://127.0.0.1:8000/gallery/"> banana </a></li> <li><a href="http://127.0.0.1:8000/about/"> grape </a></li> </ul> </nav> <hr class="solid"> </body> </html> [`<!--footer html --> {% load static %} <!DOCTYPE html> <html lang="en"> <head> … -
How to combine selection and assignment in a single Django ORM query?
I'm trying to avoid race conditions when assigning objects from a pool to another object. meerkat_pool = Meerkat.objects.filter(customer=None) customer.meerkat = meerkat_pool.first() customer.save() Simultaneous requests result in the same meerkat being assigned to two different customers. Is there a way to run this as a single database query? F() expressions would be ideal if I could transform the QuerySet to a single value (e.g. customer.meerkat = F("first_meerkat_in_pool")). -

django-auditlog: traversing relationships to get LogEntries of related objects

That is, if there is a one to many or a many to many relationship, how do pursue the relationship to get the target data? For example, if there's a one to many relationship, say Book to Genre, the LogEntry stores the id of the Genre in the change record and the hope is get the text version of the record whose id is in the LogEntry. That is, the genre for a book, say the Hobbit, might get changed from fiction to fantasy. The LogEntry record for the Hobbit might show this as … -

Potential Recommendations for a Computer Science Bachelor's Degree final project
I have a friend who will be finishing his Computer Science bachelor's degree next semestre, and he's trying to think what he could do for his final project. He plans to use Python as his main language, with potential frameworks like Kivy and/or Django. He's also considering using real data from his university if given permission for his project. So far he hasn't gotten any luck comming up with project ideas that can apply something computer science related such as AI or simulation. He also needs to make sure that it isn't exclusively an information system project (like if the project is just a simple dashboard or a normal website that won't do much). If anyone can offer any recommendations for what could be a good computer science final project for my friend i'd be very grateful. -

Why am I getting a CSRF Token Verification Error when submitting a post request using Django?

django-fsm FSMKeyField transition identifier

Is it possible to filter Django objects by a list of dictionaries?
Let's say I have a queryset of django objects i.e. Blog with fields id, hits, title and also a list of dictionaries which represent those objects: blog_list = [{'id': 1, 'hits': 30, 'title': 'cat'}, {'id': 2, 'hits': 50, 'title': 'dog'}, {'id': 3, 'hits': 30, 'title': 'cow'}] One of the django object has a value different from one specified in the list of dictionaries. For example, I have a blog instance with id = 1, hits = 30, but title = 'new cat' Right now I do: for blog in queryset: for entry in blog_list: if blog.id == entry['id'] and blog.title != entry['title']: print(f'It is the blog entry with id {blog.id}') But it looks suboptimal and too complicated. Is there a smart way to find such object? -

Following Scalingo documentation, my settings.py file contains the following lines : BASE_DIR = os.path.dirname(os.path.dirname(__file__)) STATIC_ROOT = 'staticfiles' STATIC_URL = '/static/' STATICFILES_DIRS = ( os.path.join(BASE_DIR, 'static'), ) I've been tweeking these settings for a while now, and I don't know what to try. I read a lot about whitenoise, but it don't seems compatible with ASGI (this PR is not merged yet).
