Django dynamic/runtime migrations: what's up?
I am aware that it is widly deprecated or documented in way too old posts, but I think I've got good reasons to be willing to update some of my Django models dynamically, and repercut corresponding changes into my PostgreSQL database. TL;DR What's the latest/neatest/most-django2.0-consistency-compliant way to do this? Is it at least possible or documented in any fashion? This approach only allows model creation, not deletions. I have read about django-mutant, is this module out-of-date? Can we dynamically create and resolve individual migrations? In the end, this would mean nothing but using django as a plain (yet nice and powerful) wrapper around psql, right? If I trust this post, people will first try to stop me. For this reason, I'll develop my motivation here: My core models (1) are a set of django-canonical, consistent, append only, archive tables, whose structure is simple, fixed forever and explicitly described as regular django models. No fancy stuff here. Do not panic. These non-fancy, consistent archives (1) actually describe the evolution of.. a database (2). (Thus my need for meta-* stuff.) The latter database (2) is more volatile, its shape and content will change over time. However, every change to it (2) is … -
How do I set up an AngularJS-driven form to work with Django password reset functionality?
I'm working on a web page with AngularJS v1.5.6. This page has other forms. I want to add a "Reset password" form to this page. Ideally, the form might look something like this: <div ng-app="app" ng-controller="Ctrl"> <form method="post" name="resetPWForm" ng-submit="resetPW(resetPW.email)"> <small>{{ resetPW.msg }}</small> <input placeholder="Email" type="email ng-model="resetPW.email"> </form> </div> I'd like resetPW() to go something like this: $scope.resetPW = function(email){ $http.post( {"email":email}, "path/for/resetting/email") }.then(function(response){ if(response.success==false){ $scope.resetPW.msg = "There was a problem. Please try again."; return; } alert("Success! Check your email for a link to finish resetting your password."); }); I've seen this Django password reset for tutorial: https://simpleisbetterthancomplex.com/tutorial/2016/09/19/how-to-create-password-reset-view.html. But I'm unsure how I'd apply it to my situation. My questions is how would I set up urls.py and views.py to handle this? -
Handling duplicates in django models
This is my location object class Location(models.Model): country = models.CharField(max_length=255) city = models.CharField(max_length=255, unique=True) latitude = models.CharField(max_length=255) longitude = models.CharField(max_length=255) class Meta: unique_together = ('country', 'city') This is the view in which I create a location, class LocationView(views.APIView): def post(self, request): serializer = LocationSerializer(data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) else: Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) Now while saving the new location if the database throws duplication error, then I want to not write the new value but fetch the already existent data and return it as a success response message. In sense I want to add another else clause. I'm not sure how to do this in django. Any help appreciated. -
How to save multiple files under in 1 django model
I'm fairly new to Django. I have a model copy, the model copy will contain a student test copy and a mark, usually, i would use a FileField and save the copy to the object, but my problem is that a copy could contain many files (page 1, 2, 3 etc) I was thinking about using a CharField instead that contains the path to a folder that contains the files for that copy, but I don't have a very good idea on how to do that and if you have a better way I would for you to share. here is my model class VersionCopie(models.Model): id_version = models.CharField(db_column='id_Version', primary_key=True, max_length=100) numero_version = models.IntegerField(db_column='numero_Version', blank=True, null=True) note_copie = models.FloatField(db_column='note_Copie', blank=True, null=True) emplacement_copie = models.CharField(db_column='emplacement_Copie', max_length=10000, blank=True, null=True) id_copie = models.ForeignKey('Copie', models.CASCADE, db_column='id_Copie', blank=True, null=True) i just need to know what kind of path i would save to "emplacement_copie" -

Why do I get 'this field is required' error in Django models, is there error in my code?
So I am trying to make User form where A user can Upload picture using File-field in models. I am choosing a picture still it says this field is required (after submiting the form) and unloads the pic. models.py: class Incubators(models.Model): # These are our database files for the Incubator Portal incubator_name = models.CharField(max_length=30) owner = models.CharField(max_length=30) city_location = models.CharField(max_length=30) description = models.TextField(max_length=100) logo = models.FileField() verify = models.BooleanField(default = False) def get_absolute_url(self): return reverse('main:details', kwargs={'pk': self.pk}) incubator-form.html <form method="post" novalidate> {% csrf_token %} {{ form.as_p }} <button type="submit">Submit</button> </form> I have added the following code in site's main urls.py: if settings.DEBUG: urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) And added the following to settings.py MEDIA_ROOT = os.path.join(BASE_DIR, 'media') MEDIA_URL = '/media/' I have even created media folder in the project directory. I have another class with same FileField which works fine. The problem is only in this class. -

How to reinstall requirements.txt
I'm working in this shared Django project, a colleague is the owner of the repo in Github. The problem I am facing right now is that he added raven to his packages and in github the requirements.txt file is updated, however when I tried with git pull, locally, my requirements.txt does not have raven added. He told me that I have to reinstall requirements.txt so I tried with pip freeze > requirements.txt but nothing change. How can I update my requirements.txt file according the updates made from Github? -
django rawsql postgres nested json/jsonb query
I have a jsonb structure on postgres named data where each row (there are around 3 million of them) looks like so: [{"number": 100, "key": "this-is-your-key", "listr": "20 Purple block, THE-CITY, Columbia", "realcode": "LA40", "ainfo": {"city": "THE-CITY", "county": "Columbia", "street": "20 Purple block", "var_1": ""}, "booleanval": true, "min_address": "20 Purple block, THE-CITY, Columbia LA40"}, .....] I would like to query the min_address field the fastest possible way. In Django I tried to use: APModel.objects.filter(data__0__min_address__icontains=search_term) but this takes ages to complete (also, "THE-CITY" is in uppercase, so, I am having to use icontains here. I tried dropping to rawsql like so: cursor.execute("""\ SELECT * FROM "apmodel_ap_model" WHERE ("apmodel_ap_model"."data" #>> array['0', 'min_address']) @> %s \ """,\ [json.dumps([{'min_address': search_term}])]) but this throws me strange errors like: LINE 4: @> '[{"min_address": "some lane"}]' ^ HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts. I am wondering what is the fastest way I can query the field min_address by using rawsql cursors. -

Is it possible to create view with list of objects and forms to update?
I'm trying to solve my problem with django for last 2 days, I've searched many reddit posts/ git repos / stack questions and I've achieved nothing. I'm learning django and doing a project to help me in my current job. My goal is to make detail view of model "Partner" where I'll list all it's "PartnerMugs" models.py class Partner(models.Model): partner_name = models.CharField(max_length=255) class Meta: ordering = ["partner_name"] def __str__(self): return self.partner_name def get_absolute_url(self): return reverse("partners:detail", kwargs={"pk":self.pk}) class PartnerMug(models.Model): partner = models.ForeignKey('Partner', on_delete=models.CASCADE) pattern = models.ForeignKey('patterns.Pattern', on_delete=models.CASCADE) xs_amount = models.IntegerField(default=0) xl_amount = models.IntegerField(default=0) class Meta: ordering = ["partner"] def __str__(self): return str(self.partner) + " " + str(self.pattern) def get_absolute_url(self): return reverse('partners:detail', args=[self.partner.pk]) The problem is that I have no idea how to put form for each "PartnerMug" object in my list. I tried to do something with inlineformset_factory, but I didn't find the way how to put it in my for loop. form.py class PartnerForm(forms.ModelForm): class Meta: model = Partner fields = ['partner_name'] class MugAmountForm(forms.ModelForm): class Meta: model = PartnerMug fields = ['xs_amount','xl_amount',] MugAmountFormSet = inlineformset_factory(Partner, PartnerMug, form=MugAmountForm, extra=0) For now my Class Based View looks like this(it's based on github repo): view.py class PartnerDetailView(ModelFormMixin, DetailView): model = Partner form_class = … -

Filling form with csv file data Django
What I am trying to do is filling Django form with data coming from CSV file. Idea is to let user choose whether he wants to fill a form by himself or do this by uploading data from csv file. I have been looking for a tip on stackoverflow for some time already and haven't found anything else then saving data to django-models and retrieve them later on. I don't want to save the file anywhere neither. I don't want to use django models to save the data and then upload them into a form and I was wondering - is there any way to accomplish such? Simple code to explain this a bit more: #template.html <form action="/generate/" method="post"> First name: {{ form.first_name }}<br> Last name: {{ form.last_name }}<br> <input type="submit" value="Submit" /> </form> <form method="POST" action="/upload" enctype="multipart/form-data"> <div class="form-group"> <label for="inputFile">File input</label> <input type="file" name="inputFile"> </div> <button type="submit" class="btn btn-default">Submit</button> </form> I would like to 2nd form reads the file and somehow fill with data the upper one on the same page / template to allow further validating and actions under this view. Does anyone have any ideas ? -

Django customize ForeignKey way of instances returnment
I have a need to create custom field, that is very similar to a ForeignKey field but has specific logic. Two main tasks are: Each related model of this CustomForeignKey has regular ForeignKey field to the model itself and my purpose is to return one of this instances depending on some parameter (date for example). Maybe it would be more clear with some example: class Author(models.Model): name = models.CharField(max_length = 30) surname = models.CharField(max_length = 60) publication = CustomForeignKey(Publication) class Publication(models.Model): title = models.CharField(max_length = 50) text = models.TextField() date = models.DateTimeField() source = models.ForeigKey('self', related_name='references') I want calls to SomeAuthor.publication be performed like SomePublication.references.order_by('date').first(). Real goal is more difficult, but the sense is nearly the same. Second thing is about lookups. When I filter objects by this CustomForeignKey, I would like to have same logic as in previous point. So Author.objects.filter(publication__title = 'Some Title') should make filtering by the fist object ordered by date from references related manager. I read the documentation about creating custom fields in django, but there are no good examples about custom relational fields. In django.db.models.fields.related as well, I didn't find which methods should I redefine to achieve my goal. There are to_python and from_db_value, … -
ChoiceBlock consisting of other Wagtail blocks?
I'm trying to construct the carousel model: class Carousel(blocks.StructBlock): heading = blocks.CharBlock(required=False) carousel = blocks.ListBlock( blocks.StructBlock([ ('slide', blocks.StreamBlock([ ('image', ImageChooserBlock()), ('video', EmbedBlock())]), ), ('description', blocks.RichTextBlock()), ]) ) Every slide consists of one image or video and a description. I'm using StreamBlock in here because I couldn't find any other more suitable structural block type which would allow to the user to choose between image and video. Ideally I need something similar to the ChoiceBlock, except that the choices argument should expect other block types. Is that feasible? Or at least is there a way to limit how many sub-blocks might be inserted from within the StreamBlock? -
Best practice to divide a django project into applications
I want to know how to divide a project having a hierarchical structure into applications. Let's say that I'm trying to build up something like github.com for example.

How to customize database connection settings' timezone in django?
I am looking into django db backends. I have found that datetime values' timezone are changed to and forth by django, while saving dates into db as well as retrieving them. During this conversion process, django uses database connection's timezone settings. I have seen that by default for sqlite db, 'UTC' is the timezone. I want to change the database connections options, during the start of django application. How can I do that ? Thanks in advance.
