How can I choice data is put to model or one is not do to it?
I wanna parse excel and put data in the model(User). views.py is #coding:utf-8 from django.shortcuts import render import xlrd from .models import User book = xlrd.open_workbook('../data/data.xlsx') sheet = book.sheet_by_index(1) for row_index in range(sheet.nrows): rows = sheet.row(row_index) print(rows[1]) for row in rows: user = User(user_id=row[1], name_id=row[2], age=row[3], name=rows[4]) user.save() Excel is excel I do not want to put data of row whose user_id & name column is empty.In this case,I do not want to put data of line 5 & 6 .But now, my code is to put all excel data to User model.I cannot understand how to extract excel data and put to model.What should I do to do so?I thought if content of list is empty, the data should be skipped.But list is not separate each content, for example [1,1,40,Tom] can be counted 1 list. -
Django request with user criteria
I would like to get some help about my future process. I would like that users could create his own django request and then get the result. Up to now, I created django requests in my script but there are static requests : request1 = Test.objects.all() or query_lastname_ID = request.GET.get('q1ID') query_firstname_ID = request.GET.get('q1bisID') query_naissance_ID = request.GET.get('q1terID') if query_firstname_ID and query_lastname_ID and query_naissance_ID : query_ID_list = Individu.objects.filter( Nom__icontains=query_lastname_ID, Prenom__icontains=query_firstname_ID, VilleNaissance__icontains=query_naissance_ID) if len(query_ID_list) != 0 : messages.success(request, 'Miracle .. Vous avez un résultat !') else : messages.error(request, "Oh non .. Vous n'avez aucun résultat !") All of these requests are static. Now I would like to let the choice to the user between criteria or mathematic operator. I won't write table fields in my request but the user could have the choice to get what he wants : one field two fields x fields the mathematic operator (=, >, <, not egal, ...) comparison between fields ... User could get a result thanks to a dynamic request. He could create himself Django request. Is it possible ? I don't find example or documentations about this kind of process :/ -

Django: non-nullable field without a default
In Django I use manage.py makemigrations and manage.py migrate on the following models.py file: class Family(models.Model): comment1 = models.CharField(max_length=80) #comment2 = models.CharField(max_length=80) After this succesful initialization I change models.py to (I just uncomment the new model field which is basically a copy of the other model field): class Family(models.Model): comment1 = models.CharField(max_length=80) comment2 = models.CharField(max_length=80) Now when I try to makemigrations again I get the following error: You are trying to add a non-nullable field 'comment' to family without a default; we can't do that (the database needs something to populate existing rows). Please select a fix: 1) Provide a one-off default now (will be set on all existing rows with a null value for this column) 2) Quit, and let me add a default in models.py Select an option: Why didn't I get this error upon intialization in the first place? -
Django raw sql with datetime
I use postgres for my django project, and for complicated queries to db i use connection.cursor(). Today I have a problem with raw sql query with datetime in filter: with connection.cursor() as cursor: cursor.execute( "SELECT * from orders_orderstatus WHERE datetime > '2017-09-05 16:07:16'" ) row = [item[0] for item in cursor.fetchall()] return row As result we have empty list. But if I query this from psql console, I see that result is not empty: SELECT * FROM orders_orderstatus WHERE datetime > '2017-09-05 16:07:16'; id | status | datetime ----+--------------------+-------------------------------+ 256 | created | 2017-09-05 16:10:59.602091+07 257 | delivered | 2017-09-05 16:11:00.834547+07 258 | created | 2017-09-05 16:11:03.499364+07 Why django doesn't receive this results? -
Django Wagtail Searching PDF file contents
Is there a simple tool that I can integrate to a class that inherits from the Page class that allows me to search actual text in pdf files? i.e. i have a class which has the following fields class involvedItemBlock(blocks.StructBlock): title = blocks.CharBlock(required=True, max_length=255, min_length=1) info = blocks.RichTextBlock(required=True, max_length=255, min_length=1) image = ImageChooserBlock(required=False) external_link = blocks.CharBlock(required=False) class News(Page): description = StreamField([("agenda",genericItemBlock())], null=True, blank=True) docs_en = StreamField([("documents",involvedItemBlock())], null=True, blank=True) Now having said all that each News item is an instance of the News class. I can easly search through test in the description but how do i search for text within each document of each instance as well as the documents of all instances. To reiterate i have to News items: 1) Title: 2017-01-01 movement report (this has 5 documents in it's streamfield field titled doc_en) 2) Title: 2017-01-08 government report (this has 2 documents streamfield field titled doc_en) I would like to search a total of 7 documents, what library or tool could do this efficiently and hopefully can be integrated with Django/Wagtail. -

Delete method on Django Rest Framework ModelViewSet
i have tried to delete a single ManuscriptItem instance using Postman to perform my API requests on against the view below: class ManuscriptViewSet(viewsets.ModelViewSet): """Handles creating, reading and updating items.""" authentication_classes = (TokenAuthentication,) serializer_class = serializers.ManuscriptItemSerializer permission_classes = (permissions.PostOwnManuscript, IsAuthenticated,) def perform_create(self, serializer): """Sets the user profile to the logged in user.""" serializer.save(author=self.request.user) def get_queryset(self): """ This view should return a list of all the manuscripts for the currently authenticated user.

This is what it returns when i tried: { "detail": "Method \"DELETE\" not allowed." } This is how my URLs are currently registered: router = DefaultRouter() router.register('manuscripts', views.ManuscriptViewSet, base_name="manuscripts") # auto basename for models router.register('manuscriptlibrary', views.ManuscriptLibraryViewSet, base_name="manuscript_library") router.register('manuscriptsettings', views.ManuscriptSettingsViewSet) urlpatterns = [ url(r'', include(router.urls)) ] I'm i modifying the ModelViewSet wrong do i need to use another approach because of the nature of ModelViewSet? i expected it to work on Postman when i used an Authorized user to Delete a ManuscriptItem instance. In the docs it said Destroy() method can be used. -
Django Rest Swagger -> No Authentication + multiple apps
We are looking to use django swagger for generating REST API docs. Our app consists of many sub apps and all views use JWT authentication. Document seems very lacking and just mentions the adding of url.

Django model fields from constants?
How to define a Django model field in constant and use everywhere. For example, if I have a model like:- class Author(models.Model): first_name = models.CharField(max_length=30) last_name = models.CharField(max_length=40) email = models.EmailField() And what I want to do is define constant for fields in Author model and provide the constant instead of field name in model like:- KEY_FIRST_NAME = 'first_name' KEY_LAST_NAME = 'last_name' KEY_EMAIL = 'email' And Author model should use the constant instead of exact key like:- class Author(models.Model): KEY_FIRST_NAME = models.CharField(max_length=30) KEY_LAST_NAME = models.CharField(max_length=40) KEY_EMAIL = models.EmailField() How to do something like this, direct assignment to constant won't work here. The purpose of doing this is If there is any change in filed name in future version then I want to only change at one place and it should reflect on all the places. -

Django model calculated field from one to many relationship
I have inherited some code with a django API and am trying to understand / get to grips with how to modify it appropriately.. I have a Model class called Asset and a Model class called Calibration. A Calibration has a many to one relationship with Asset so: class Calibration(Record): ... asset = models.ForeignKey(Asset, relatedName = "calibrationRecords") ... And when I look at an individual Asset I can see the Calibration records as one would expect. On another section of the API I can list all the Assets for a given Customer, however on this page, the calibrationRecords link is not shown. This is kind of OK as I don't actually want to see all the Calibration records on this view, but I would like to see the last (most recent) Calibration record here, so in essence adding a calculated field onto this Model? Where should this calculation go, and how is the best way to do it? -
