How can I create group of objects to store information?
I have two models Pigeons and Treatment. Every pigeon can have multiple treatment. I want to create some groups of pigeon like all pigeons, cock, female, squeakers and when I want to create a treatment to select the group and assign the medication. #models class Pigeons(models.Model): ring= models.CharField(max_length=25, null=False, blank=False, unique=True) status = models.ForeignKey(PigeonStatus, on_delete=models.CASCADE, null=False, blank=False) ...... class Treatment(models.Model): date = models.DateTimeField(default=timezone.now, null=True, blank=True) # we can treat only one pigeon pigeon = models.ManyToManyField(Pigeons, on_delete=models.CASCADE) # or select group to assign medication group = ...... medication = models.ForeignKey(Medication, on_delete=models.SET_NULL) Which is the best approach to do this?

Add to same template another ListView depending on previous ListView item selection Django
How can I pick one item in a ListView and list further items which are an array field of that item and allow them to be picked? For example: I have a model that has as its field two other models as ArrayModelFields (which is a Djongo class for MongoDB integration, functions like a formset) class LobDetail(models.Model): lob_name = models.CharField(max_length=64, primary_key=True, choices=LOB_CHOICES, default='thanks') #type = models.CharField(max_length=20, choices=TYPE_CHOICES) source = models.ArrayModelField( model_container = Source, ) destination = models.ArrayModelField( model_container = Destination, ) def __str__(self): return self.lob_name + " "+ self.type (where Source and destination are two abstract models) I have a template file that shows a ListView of all the available LobDetails. I have added a link along with each list item that allows me to pick that item. Now I want to list all the sources and destination, depending on that picked item and further allow me to pick one amongst them. All of this I want to do on the same page. But I can't figure out how? -

manage create method of django when there are lots of fields
I am working on project where I have taken django in backend. I have a model call profile which is related to the user. A profile model has more than 10 fields and when trying to update the user profile, my code for updating all those fields would be something like this class UpdateProfile(graphene.Mutation): class Arguments: input = types.ProfileInput(required=True) success = graphene.Boolean() errors = graphene.List(graphene.String) profile = graphene.Field(schema.ProfileNode) @staticmethod def mutate(self, info, **args): is_authenticated = info.context.user.is_authenticated data = args.get('input') if not is_authenticated: errors = ['unauthenticated'] return UpdateProfile(success=False, errors=errors) else: profile = Profile.objects.get(user=info.context.user) profile = models.Profile.objects.get(profile=profile) profile.career = data.get('career', None) profile.payment_type = data.get('payment_type', None) profile.expected_salary = data.get('expected_salary', None) profile.full_name = data.get('full_name', None) profile.age = data.get('age', None) profile.city = data.get('city', None) profile.address = data.get('address', None) profile.name_of_company = data.get('name_of_company', None) profile.job_title = data.get('job_title', None) profile.zip_code = data.get('zip_code', None) profile.slogan = data.get('slogan', None) profile.bio = data.get('bio', None) profile.website = data.get('website', None) profile.github = data.get('github', None) profile.linkedin = data.get('linkedin', None) profile.twitter = data.get('twitter', None) profile.facebook = data.get('facebook', None) profile.image=info.context.FILES.get(data.get('image', None)) profile.save() return UpdateProfile(profile=profile, success=True, errors=None) so my question is, suppose, if there are even more than 20, 30 fields, how would you design your code on updating those fields?

How can I make a page that will always display the latest post from my Django Model
Thank you to all of the people who looked at this in advance! I really appreciate it. I have setup a very simple model that consists of two parameters (title, which is the date when this was published and the text, that's it): models.py class Post(models.Model): title = models.DateField(blank=True, null=True) body = models.TextField() def __str__(self): return str(self.title) After following a standard "create a blog in Django tutorial" I have created two views that show the list of everything posted and a view that will show details of any selected post. views.py class NowListView(ListView): model = Post template_name = 'archive.html' class NowDetailView(DetailView): model = Post template_name = 'then.html' Finally, I have this urls.py that successfully shows all the posts at http://127.0.0.1:8000/now/archive and specific post at http://127.0.0.1:8000/now/archive/1 (or any other number, depending on the pk). urls.py urlpatterns = [ path('archive', NowListView.as_view(), name='archive'), path('archive/<int:pk>', NowDetailView.as_view(), name='then'), ] What I want to achieve is to display the latest post on http://127.0.0.1:8000/now. I have tried a million ways to do it, and nothing worked, always something in the way (would take too long to write all of them). After all this tries it is obvious to me that I have to use a query to … -
List available SRID values in GeoDjango
What is the easiest way to generate a list of SRID values and their WKT names/titles. There should be about 3000 values that are listed in the table SPATIAL_REF_SYS. Are there Django models that I can load to access this info or do I need to create a sql query to access the info? -
Using user_passes_test Restrict Access to View by Group or Logged in User
Users have individual profiles where I am trying to restrict their access to their individual profile while allowing users in an admin Group to access all profiles. Ideally I was hoping to accomplish this by way of the decorator user_passes_test with one function. If need be I could use two different functions with a decorator for each. Though combining all into one may be cleaner. # Views.py def profile_access(CustomUser, request): officer = CustomUser.groups.filter(name='Officer') logged_in_user = request.self.CustomUser if officer or logged_in_user: return True else: return redirect('homepage') @user_passes_test(profile_access) def profile(request, pk): # Profile content here I am not sure how to identify the logged in user to restrict them to their Profile only while also allowing users in the Officer group to see all Profiles. -
How do I store information about a front-end button on the Django server?
Basically I want to store a buttons service server-side that way it can persist through browser closes and page refresh. Here's what the user is trying to do The user searches in a search bar for a list of products. When the results show up, they are shown a button that triggers an action for each individual product. They are also shown a master button that can trigger the same action for each product that is listed. Upon clicking the button, I want to disable it for 30 seconds and have this persist through page refreshes and browser close. What I've done Currently I have this implemented using AJAX calls on the client side, but if the page refreshes it resets the button and they can click it again. So I looked into using javascript's localStorage function, but in my situation it would be better just to store this on the server. What I think needs to happen Create a model in my Django app for a button. Its attributes would be its status and maybe some meta data (last clicked, etc). Whenever the client requests a list of products, the views will send the list of products and it … -

Implement bulk save in django admin using another model
Assuming I wanted to track which countries airlines fly to. I might have a model Airline and a model Country with a many-to-many relationship between them. Say I made that through model explicit and called it CountryCoverage with a foreign key each to Airline and Country. All is working well but now I want to add a new airline which happens to cover the whole world. While there are other options, going through Django admin would require a new entry in CountryCoverage for each country/airline combination... a lot of manual work. As it happens the Country model has a many-to-many relationship with another model called CountryGroup. Ideally what I would like to do is to show CountryGroup on the CountryCoverage admin page and if the user selects the combination Airline X / Global coverage then I would like to automatically save an entry for each Airline X / Country combination. How can I best achieve this? I saw that it is possible to display another model on the admin page and to overwrite the save method so I thought of combining the two somehow. -
Django sqlite3 database displayed on HTML table
I'm trying to filter (by column element) and display information from a sqlite3 database directly onto a HTML table. I've read in multiple places that you should use Django's ORM instead of a database. However, the data is continuously updating in the database so I'm not sure if this is a route to pursue with this. TL;DR I'm looking for a way to open a sqlite3 .db file and chuck it into an HTML table. I have looked over the django documentation regarding models, as well as looked at several different websites/tutorials (here, stack overflow; I even found django-tables2 which I thought was going to work), all to no avail. I'm essentially at a roadblock and I'm not sure where to go and/or what to do. Here is how the database is structured: --------------------------------------------- | Name | Type | Col 1 | ... | Col N | Color | --------------------------------------------- | Gary | A | Data | ... | Data! | Green | | Mark | A | Data | ... | Data? | Blue | | Ray | B | Data | ... | Data. | Red | ...
