How to inject varaible from html to views.py in Django 2?
I tried some ways but none worked. Button should scrape weather from city typed in the text box. All scraping works when i hardcode city name but i don't know how to get that city name from html form to views.py.

Passing arguments to dispatch methods
I am relatively new to Python and Django. I am parsing Excel sheets and want to store the data in a DB (MySQL). The information in which table the data is stored is available through the Excel sheet. I'd like to use a dispatch table to decide which Object is stored. The fields needed can vary. I found something that I hoped would work, but unfortunately does not: python: dispatch method with string input func_name_dict = { 'Assay': Assay.objects.get_or_create() } def dispatch(name, *args, **kwargs): return func_name_dict[name](**kwargs) dispatch('Assay', 'name='ChIP-Seq') I would hope that the new object would get stored or fetched and returned to the caller. What seems to happen is that the 3 existing DB records (which all have a different name) are fetched: website.models.MultipleObjectsReturned: get() returned more than one Assay -- it returned 3! -

So I am learning the django rest framework and have a simple setup. I have a user model and ads model setup that relationallly mapped to echother. I have the viewset setup when I search up users I can see the ads that are associated with that user. The problem is, when I go to add a user it is requiring that I have enter in ads.

Iterate and format dictionary returned by template filter
I'm trying to display metadata about an image in my Django app. The metadata is read from the image's exif header and stored in a dictionary with the image as a key, and returned to the template with a filter. In my template, I display the images, and would like to display the formatted metadata for that image. So far I can only get it to display the dictionary for that image (e.g. {'key1': 'value', 'key2', 'value'}). I would like it to look like key1: value, key2: value. #template.html {% block content %} {% for image in images %} {{ exif|get_item:image }} <p><img src="{{ image.image.url }}" width="500" style="padding-bottom:50px"/></p> {% endfor %} {% endblock %} #views.py def image_display(request): images = image.objects.all() exif = {} for file in images: cmd = 'exiftool ' + str(file.image.url) + ' -DateTimeOriginal -Artist' exifResults = (subprocess.check_output(cmd)).decode('utf8').strip('\r\n') exif[file] = dict(map(str.strip, re.split(':\s+', i)) for i in exifResults.strip().splitlines() if i.startswith('')) context = { 'images': images, 'exif': exif, } @register.filter def get_item(dictionary, key): return dictionary.get(key) return render(request, 'image_display.html', context=context) I thought I could just do {% for key, value in exif|get_item:image.items %} in the template, but that returns an error: VariableDoesNotExist at /reader/image_display Failed lookup for key [items] in <image: … -

How can we initiate Multi User Project Management System in Django Framework Balaji Shetty 10:29 PM (0 minutes ago) High Can anyone please suggest me how can we initiate Multi User Project Management System> Scenarios is Like For Example, Suppose we have to develop University management System Level One- University Principal as Super User Level 2 - University May have N Department like Engg, Medical, Pharmacy, Accounting, ....... N Dept Level 3- There are sublevels under every Level like Engineering will have All Engineering Branches like CS, CE, IT , EXTC, MECH, PROD ...... Same is true for other Departments. Level 4 - Same thing get repeated recursively repeated as in Level 3, in Subsequent Level. And User Hierarchy is From TOP to Bottom means Top user can see all Sub Level in Down Section But Bottom user cannot see in TOP section. Most Important Thing is User in One Level May transfer his load to user in another Same Level and We have to keep the log of Every User with respective Task. Can you please suggest me the best way to accomplish the project because User May have many to Many Relationship with Departments also. -
Is it possible to override the error message that Django shows for UniqueConstraint error? (IntegrityError)
Using UniqueConstraint on multiple fields and it is working properly, but I want to override the error message. Have gone through many postings, some of them quite dated, and none seem to specify how to override this particular instance. (IntegrityError) Fields are User and Skill Group. I would like error message to simply say "Skill Group already in use." It currently reads "Skill group with this User and Skill group already exists." Thanks. -

staticmethods with django webservice - unexpected behavior. Should create only 1 instance (singleton)
@staticmethod in django is not working. static method should be executed only one. However, for testing I made 3 calls in parallel, and static method was called 3 times. Following is the code and output: Code: class KafkaReceiver: _kafka_consumer = None def __init__(self, topic): KafkaReceiver._kafka_consumer = self.create_only_one_consumer() @staticmethod def create_only_one_consumer(): if KafkaReceiver._kafka_consumer is None: KafkaReceiver._kafka_consumer = KafkaConsumer(KafkaReceiver._topic) print("Consumer Created......") return KafkaReceiver._kafka_consumer Output: Consumer Created...... Consumer Created...... Consumer Created...... Parallel call code: r1 = grequests.get('http://localhost:5014/message/?message=hello', callback=do_something)#, hooks = {'response' : do_something}) r2 = grequests.get('http://localhost:5014/message/?message=helloworld', callback=do_something)#, hooks = {'response' : do_something}) r3 = grequests.get('http://localhost:5014/message/?message=hellothere', callback=do_something)#, hooks = {'response' : do_something}) grequests.map([r1, r2, r3]) What is expected: For each call to django webservice, django creates (I think) a new thread. However, the class here should not create instance of consumer. Is it a lock issue (I tried lock and RLock, it is not working with django) Second strange thing is on further django calls this static method is not executing. -
What are the options for ways to get Data for my project?
I'm creating a Django project that shows various music festival related info (something like this). The problem that I need data for the database. As you can imagine information regarding festivals is constantly changing and from comes many sources. For this reason I'm trying to think of some way to populate the database without updating festival lineups manually everyday. As I couldn't find any API to use, I tried using BeautifulSoup (user press a button in Django admin site, triggering the scraping process), but a lot of festival websites uses Ajax to populate parts of the DOM. So I wonder, maybe there are better solutions? I would appreciate if anyone would provide ideas/best practices/documentation to read for similar case like this. Thanks. -
How to fix "Django_Jalali" utcoffset(dt) in django models?
I'm using django_jalali as Persian calendar into my Django project and I wanted to add auto_now_add and auto_add for created_at and updated_at variables that hold time.

Order of Django Queryset results
I'm having trouble understanding why a Queryset is being returned in the order it is. We have authors listed for articles and those get stored in a ManyToMany table called: articlepage_authors We need to be able to pick, on an article by article basis, what order they are returned and displayed in. For example, article with id 44918 has authors 13752 (‘Lee Bodding’) and 13751 (‘Mark Lee’). I called these in the shell which returns : Out[6]: <QuerySet [<User: Mark Lee (MarkLee@uss778.net)>, <User: Lee Bodding (LeeBodding@uss778.net)>]> Calling this in postgres: SELECT * FROM articlepage_authors; shows that user Lee Bodding id=13752 is stored first in the table. id | articlepage_id | user_id -----+----------------+--------- 1 | 44508 | 7781 2 | 44508 | 7775 3 | 44514 | 17240 …. 465 | 44916 | 17171 468 | 44918 | 13752 469 | 44918 | 13751 No matter what I try e.g. deleting the authors, adding ‘Lee Bodding’, saving the article, then adding ‘Mark Lee’, and vice versa – I can still only get a query set which returns ‘Mark Lee’ first. I am not sure how else to debug this. One solution would be to add another field which defines the order … -
Django and React
I haven't been able to locate anything saying one way or the other, but does anyone know if you can have function based views in django and have react as your frontend? No use of templates. If so, would it look like this? # fad index route def fad_index(request): context = {'fads': Fad.objects.all()} return render(request, 'fad/fad_index.html', context) But instead of fad_index.html, would it just be the route that you want it to take in react? -

How should I implement reCaptcha v3 if my front and backend live on different domains?
I have several websites (SPAs), each one running on it's own domain. All these SPAs use the same API, which is hosted on another domain. I'd like to implement reCaptcha v3 on my SPAs, but I'm not really sure how exactly the entire validation process would work. Who would be in charge of receiving the callback from Google's service? If the backend, how does the frontend validate itself to the backend? The SPAs are made with Vue and the backend is a Django app with Django Rest Framework. The backend is stateless, so there are no cookies. -
