How to avoid import-time database access in Django?
My Django app has a number of categories for things which I store in a Category model. I reference these frequently in code, and so I've found it useful to have a module with references ("constants") to these categories and groups of them, so typos will fail fast. This also provides the benefit of caching. And finally, it's the actual model so it has all the related functionality. It looks something like this: def load_category(name): return Category.objects.get(name=name) DOGS = load_category("dogs") CATS = load_category("cats") However, this results in import-time database access and causes various issues. After adding a new category with a reference like this, I must run a data migration before ./manage.py will function. I just hit a new problem while switching to using Django's test framework, which is that these load from the default (e.g., dev or prod) database rather than the test one as explicitly mentioned in this warning. If your code attempts to access the database when its modules are compiled, this will occur before the test database is set up, with potentially unexpected results. For example, if you have a database query in module-level code and a real database exists, production data could pollute your tests. … -
How to send an entire XML file through Curl in the POST request in django rest
I need to send a XML file through curl as a data . But I am not able to see the top and bottom part of the file in request.body . Only the middle part of the XML file is present in the request.body . Using the Curl I tried to invoke my Django rest endpoint DELETE method. Curl Command went through but the file got stripped off on the top and bottom on the receiving end.(i.e) the request.body content contains only the middle part curl -k -i --user user:passwd -H "Content-Type: application/xml" -X DELETE --data "@sample.xml" https://sample_machine:8000/api/test/ Please let me know what went wrong here. Even I tried a smaller file sending as an input.But the same thing happened. -
Add streamfield to search index in Wagtail
I struggle to add my streamfield to the wagtail search index. This affects boths the available or the custom blocks. From what I've found in the mailing list, a custom block should implement get_searchable_content which all blocks do. here is my model which I'd like to index: class BlogPage(Page): author = models.ForeignKey(User, on_delete=models.PROTECT) date = models.DateField("Post date") main_category = models.ForeignKey('blog.BlogCategory', related_name='main_category', default=1, on_delete=models.PROTECT) categories = ParentalManyToManyField('blog.BlogCategory', blank=True, related_name='categories') readtime = models.IntegerField(blank=True, null=True) subtitle = models.CharField( verbose_name=_('subtitle'), max_length=255, help_text=_("The page subtitle as you'd like it to be seen by the public - also the blog post teaser."), ) body = StreamField([ ('heading', general.TitleBlock()), ('paragraph', blocks.RichTextBlock()), ('image', general.FillImageChooserBlock()), ('subtitle', general.SubTitleBlock()), ('pullquote', general.PullQuoteBlock()), ('blockquote', general.BlockQuoteBlock()), ]) cover = models.ForeignKey( 'wagtailimages.Image', on_delete=models.PROTECT, related_name='+' ) content_panels = Page.content_panels + [ MultiFieldPanel([ FieldPanel('subtitle'), FieldPanel('date'), FieldPanel('main_category', widget=forms.Select), FieldPanel('categories', widget=forms.CheckboxSelectMultiple), ImageChooserPanel('cover'), FieldPanel('author'), ], heading="Blog information"), StreamFieldPanel('body'), ] search_fields = Page.search_fields + [ index.FilterField('date'), index.FilterField('main_category'), index.SearchField('body'), index.SearchField('subtitle'), ] def get_context(self, request): context = super().get_context(request) context['posts'] = BlogPage.objects.exclude(id=self.id).order_by('-date')[:10] return context def save(self, *args, **kwargs): if self.body.stream_data: self.readtime = read_time_as_minutes(self.body.stream_data) return super().save(*args, **kwargs) thx for any hints :) -
How to handle a list of forms with django?
For my django app, I have a form from a ModelForm as it is made to modify one property on objects in database. It works well for one object, but I would like to display a page where I can modify all the objects at once. What I have now: form django import forms class FruitForm(forms.ModelForm): class Meta: model = Fruit fields = ('score',) widgets = {'score': forms.RadioSelect(),} the model: from django import models class Fruit(models.Model): name = models.CharField(max_length=20) score = models.ChoiceField(choices = [('bad',), ('neutral',), ('good',)]) the view: def fruit_score(request): name = Fruits.objects.get(name='Orange') if request.method == 'POST': form = FruitForm(request.POST) if form.is_valid(): form.save() else: form = FruitForm(None, initial={'name': name}) return render(request, 'fruit/test_fruit.html', locals()) and the following template: {%extends "base.html"%} {%block content%} {{name}} <form action="{% url "fruits.views.fruit_score "%}" method="post"> {%csrf_token%} {{form}} <input type="submit" value="Submit"> </form> {%endblock%} The result I would like looks like satisfactory survey: a table on which each row is composed of a label and a choice field (radiobutton rated from 'bad' to 'good'). Moreover, I would like to add a submit button for each row and a submit button for the whole page such that the user can decide to submit only few anwser or all the answer … -

Django RemoteUserBackend Not Cleaning Username
From the instructions, I have successfully activated django's remote user authentication (see associated snippet below from SETTINGS.py). Active Directory is being used for remote authentication. # snippet from SETTINGS.py MIDDLEWARE_CLASSES = ( ... 'django.contrib.auth.middleware.RemoteUserMiddleware', ... ) AUTHENTICATION_BACKENDS = [ 'django.contrib.auth.backends.RemoteUserBackend', 'django.contrib.auth.backends.ModelBackend', ] As expected, when a user logs in for the first time, because the user doesn't exist yet, django will create the user. However, when the user is created, the user's username field has a <domain>\<username> format (e.g. "Domain1\PersonA"). In an attempt to remove domain from username, following django docs, I have updated the clean_username() method within the RemoteUserBackend class: def clean_username(self, username): return username.split('\\')[1] But, newly created user objects still have the username incorrectly set to the <domain>\<username> format. What am I missing? -
Router data to several Databases with my Django website
I would like to handle several databases with my Django Project but I need some advices about possibilities from my process. I have 3 applications in my project and I would like to separate databases like these : Database 1 : EC_local auth_* (auth_user, auth_group, ...) django_* (django_session, ...) application 1 Database 2 : EC_global application 2 application 3 Why this process ? Because my Django project will be deploy in 10 institutions. Each institution has to keep secret authentification key, users, ... in EC_local Database. However, all institutions have to share some informations thanks to application 2, application 3, ... in EC_global Database. I'm trying to simulate some virtualservers with both Databases but there are some things, especially Database routers that I don't understand. In my settings.py file, I have : DATABASES = { 'default': {}, 'global': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'EC_global', 'USER': 'osx', 'PASSWORD': '******', 'HOST': '******', 'PORT': '3306', 'OPTIONS': { 'init_command': 'SET innodb_strict_mode=1', }, } 'auth': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'EC_local', 'USER': 'osx', 'PASSWORD': '*****', 'HOST': '******', 'PORT': '3306', 'OPTIONS': { 'init_command': 'SET innodb_strict_mode=1', }, } } Then, I created a file which is named : routers.py At this moment, I don't really know what I have … -
Django makemigrations Issue
I am stumped. I have a custom model field class that looks for two arguments: app_name and file_dir. In my model definition I have this: files = MultiFileUploadAndViewer(app_name = getAppName(), file_dir='RequestedFiles', blank=True) getAppName() is: #appconfig imported from apps.py def getAppName(): return <appConfig>.name And the custom field definition is: class MultiFileUploadAndViewer(models.FilePathField): def __init__(self, *args, **kwargs): print(kwargs['app_name']) self.app_name = kwargs.pop('app_name') self.file_dir = kwargs.pop('file_dir','') + '\\' self.path = MEDIA_ROOT + '\\' + self.app_name + '\\' + self.file_dir self.upload_url = reverse(self.app_name +':File Upload') + '\\' + self.file_dir kwargs.update({'path':self.path}) super(MultiFileUploadAndViewer, self).__init__(*args, **kwargs) I deleted everything in the migrations folder except for init.py. Upon running makemigrations, it throws a KeyError complaining that 'app_name' is not in kwargs. However, notice the call to print() in the fields init method. That successfully prints the app_name. The KeyError comes after. Is the init function being called twice or something? Thus throwing the error after 'app_name gets popped off of kwargs? How can I address this issue? If I provide a default for app_name in the pop() method, this works, but I want it to error out if app_name (or file_dir) are not present in kwargs. -
Trying to activate Django signal in my test
Hey I am trying to activate a signal in my test - but I can not seem to make it work. This is my receiver @receiver(post_save, sender=models.Allocation, dispatch_uid="close_overdue_invoice_tasks") So how can "activate" it so it will call the method: def close_overdue_invoice_tasks(sender, **kwargs): ... All the signals works and my guess is that you manually have to activate the signals when running the tests. I am using Pytest by the way. -

How to create a custom related manager in Django?
class ModelA(Model): pass class ModelB(Model): modela = ForeignKey(ModelA, on_delete=CASCADE) class ModelC(Model): modelb = ForeignKey(ModelB, on_delete_CASCADE) In this case Django will automatically create a few additional managers for us. For example, if ma is an instance of ModelA, then we can write: ma.modelb_set.all(), and if mb is an instance of ModelB, then we can write: mb.modelc_set.all(). It would be convenient to be able to reference all ModelC instances related to ModelA. Of course, if ma is an instance of ModelA, we can always write: ModelC.objects.filter(modelb__modela=ma).distinct(). However, it would be more convenient if we could define a manager for ModelA that would allow us to write: ma.modelc_set.all() How to write such a manager for ModelA? -

Is there a way to have dictinary-like field in Django model?
Suppose, I am making a movie rating app. A logged-in user should be able to rate the movie with stars (in the range 1 to 5). I want to quickly access all the rater's name along with their rating. If a user rates the movie again, the rating should be updated. At the same time, if a user decides to withdraw his rating i.e. provide zero rating, I would like to remove the entry from the field. I believe dictionary would be the best choice to achieve the same. However, I am open for suggestions.
