How to use more than two models in the same form using modelForms?
I am creating a new application using Django, my application is in need of a form to add data on the db. I am using 4 models which are all connected by foreign keys. How can I use modelForm's to enter data to the form and add them directly to db, if it's not possible what should be my approach? I checked the existing solutions which are for 2 models only, I couldn't find a way to tweak it to my own problem. I tried using inlineformset but as I said couldn't figure out how can I implement it with all my models together. I also looked through the Django documentation couple times but couldn't find anything this sort (maybe I am missing). My models are like this: class Question(models.Model): year = models.CharField(max_length=5) source = models.CharField(max_length=140) problemNumber = models.CharField(max_length=16) weblink = models.CharField(max_length=200) date_posted = models.DateTimeField(default=timezone.now) problemStatement = models.TextField() author = models.ForeignKey(User, on_delete=models.PROTECT) class QLevel(models.Model): qID = models.ForeignKey(Question, on_delete=models.CASCADE) level = models.CharField(max_length=16) class QMethod(models.Model): qID = models.ForeignKey(Question, on_delete=models.CASCADE) method = models.CharField(max_length=40) class QSubject(models.Model): qID = models.ForeignKey(Question, on_delete=models.CASCADE) subject = models.CharField(max_length=35) As can be seen 3 of the models are connected to Question model with a foreign key, whilist Question model is … -
What is the best way to organize images on a file system?
I have a site where I'd like to store multiple images (profile images, profile cover images, status images, etc.) What is the best way to store images on a file system? For example, would something like: Images avatars -ex1.jpg -ex2.jpg -ex3.jpg covers -ex1.jpg -ex2.jpg -ex3.jpg This is how Twitter lays out its images, will this make the file system sluggish? Or is better to do something like this: Images avatars user1 -ex1.jpg -ex2.jpg -ex3.jpg covers user1 -ex1.jpg -ex2.jpg -ex3.jpg What is the best way to organize images in a file system? -

How can I filter products to show only those belonging to selected category in Django Admin?
I am trying to filter the options shown in a foreignkey field within Django Admin inline. Using formfield_for_foreignkey I'm able to show products with category_id = 4 but instead of the 4 I would like to filter based in the category field in the inline.

login with facebook is not working django graphql

How can I override "settings_overrides" variable in leaflet_map from within inside Django template
Summary I have a geodjango project to display web maps. Which I can do with no problem. However, I want to customize my map configuration from within my django template instead of from my django settings. (From django settings I can do it alright). To customize, I have to pass a python dictionary to a variable called settings_overrides. The problem is I can not figure it out how and if this is possible from within a django template. Description Let's say I want to override "SPATIAL_EXTENT" inside my template code where python dictionary that leaflet_map expects is like this: ext = {'SPATIAL_EXTENT': (-154.609, 1.561, -40.611, 65.921)} settings_overrides = ext Note: This is what I understood!! I might be wrong! See below for the signature of the leaflet_map function. This is calling function inside the template(index.html) where I want to pass the new extent to the setting_overrides: {% leaflet_map "main" callback="window.map_init_basic" creatediv=False, settings_overrides=ext %} (A) And the signature of the leaflet_map function which is located in: leaflet/templatetags/leaflet_tags.py is as follow: def leaflet_map(name, callback=None, fitextent=True, creatediv=True, loadevent=app_settings.get('LOADEVENT'), settings_overrides={}): if settings_overrides == '': settings_overrides = {} instance_app_settings = app_settings.copy() instance_app_settings.update(**settings_overrides) .... (B) As you can see from (B) in the signature, I have … -

I have tried creating a foreign key in my profile model that refrences the user model however, I could not get that to work. models.py class Profile(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) bio = models.CharField(max_length=2000) instrument = models.CharField(max_length=255, choices=instrument_list, blank=True) level = models.CharField(max_length=255, choices=level_list, blank=True) preferred_language = models.CharField(max_length=255, choices=language_list, blank=True) time_zone = models.CharField(max_length=255, choices=time_list, blank=True) def create_profile(self, bio, instrument, email, level, preferred_language, time_zone): profile_obj = self.model(bio=bio, instrument=instrument, level=level, preferred_language=preferred_language, time_zone=time_zone) # add arguments full_name=full_name profile_obj.save(using=self._db) return profile_obj views.py def profile_page_edit(request): if request.method == 'POST': form = ProfileForm(request.POST) if form.is_valid(): bio = request.POST.get('bio', '') instrument = request.POST.get('instrument', '') level = request.POST.get('level', '') preferred_language = request.POST.get('preferred_language', '') time_zone = request.POST.get('time_zone', '') #profile = request.user #form.save() profile_obj = Profile(bio = bio, instrument = instrument, level = level, preferred_language = preferred_language, time_zone = time_zone) profile_obj.save() return redirect('/student/profile-page') else: form = ProfileForm() form = ProfileForm() context = {'form': form } return render(request, 'student/profile_page_edit.html', context) def profile_page(request): form = ProfileForm profiles = request.user.profile.objects.all() args = {'form' : form, 'profiles' : profiles} return render(request, 'student/profile_page.html', args) I am trying … -

Is it possible to use/test a value of Django's BooleanField without a model?
I'm trying to make a workflow where the user enters data on one page, then has to check the data and tick a tickbox to accept the T&C's. So the code has to check that the checkbox is checked before going on, but doesn't care until the second step. It's not a bound field and I think that's the problem - I don't need a model just to handle a workflow, and I don't want to have to store, in a database, a simple ephemeral field in a form! I'm running Django 2.1.5. I've tried every possible combination of: test_form.fields['tickbox'].value - doesn't exist, which is ridiculous test_form.fields['tickbox'] == False - value doesn't change at all request.POST['tickbox'] seems to go missing? views.py from django.http import HttpResponse from django.template import loader from django.forms import Form, CharField, BooleanField class test_form(Form): name = CharField() tickbox = BooleanField(required=False, initial=False) def testview(request): if request.method == 'POST': testform = test_form(request.POST) if testform.fields['tickbox'] == True: do_things() else: dont_do_things() else: testform = test_form() template = loader.get_template('testform.html') context = { 'testform : userform, } return HttpResponse(template.render(context, request)) I should be able to test the value of the field and get a changing response depending on if the user has ticked … -

Rest Framework serializer to create parent and one of multiple child types
I have a serializer that creates a parent model, then creates a child model depending upon some information provided to the parent: class InitializeFormSerializer(serializers.Serializer): title = serializers.CharField() category = serializers.ChoiceField(choices=CATEGORY_TYPES) def create(self, validated_data, user): identifier = validated_data.get('title') obj, created = Parent.objects.update_or_create( user=user, ) if created: item_type = validated_data.get('item_type') if item_type == 'FIRST_TYPE': Child1.objects.create(identifier=obj) elif item_type == 'SECOND_TYPE': Child2.objects.create(identifier=obj) return obj This works, but the item_type check feels clumsy. Is there a paradigm within Django or Rest Framework I'm missing that might make this more elegant? -

How to generate thumbnails in MEDIA_DIR from images stored in STATIC_DIR with Django?
I have a number of images stored in my static dir, set as per my django settings. These images are all different sizes and aspect ratios. They display fine in my django application at the moment. I want to generate thumbnails from these images using "smart crop" functionality (which looks for the parts of the image with the most entropy when reducing instead of just centering). I've tried this both with sorl-thumbnail and the easy_thumbnail packages that have the "smart crop" functionality I am after. In both cases, I get an error: SuspiciousFileOperation at /products The joined path (/static/images/products/test1.jpg) is located outside of the base path component (/home/jake/webapps/my_webapp/my_site/media) I understand that media and static dirs are meant to be distinct from each other, with media being for where users upload files and static being files that are part of the site. But, since thumbnail packages need to read images from my static dir and generate them in my media dir, how can I resolve this security conflict? Surely this should be a common configuration for people generating thumbnails, basin them on images in their static dir? Yet I can't find anything on this error coming up in this context before, … -
multiple field search in dajngo app wrong results
I would like to create a multiple field search for the my database in django app. my search work correct only if the user use all fields from html form. if the user don't use some field or if some field is empty or blank then my query return all results (like apps=movies.objects.all() ) and that is wrong because the user in not required to use all fields but anytime to use fields where need for search. any idea how to fix that ? here my code: models.py : class category(models.Model): title = models.CharField(max_length=100, blank=True, null=True) class movies(models.Model): code = models.CharField(max_length=100, blank=True, null=True) code_2 = models.CharField(max_length=100, blank=True, null=True) name = models.CharField(max_length=100, blank=True, null=True) year = models.CharField(max_length=100, blank=True, null=True) movies_title=models.ForeignKey('category', blank=True, null=True) link=models.CharField(max_length=100, blank=True, null=True) html form : <form method="POST" action="{%url 'search' %}">{% csrf_token %} <select name="link"> <option value=""></option> <option value="0">link 1</option> <option value="1">link 2</option> <option value="2">link 3</option> </select> <select name="category"> <option value=""></option> {% for data in cat%} <option value="{{ data.id }}">{{ data.title }}</option> {% endfor %} </select> <select name="year"> <option value=""></option> {% for data in apps%} <option value="{{ data.id }}">{{ data.year }}</option> {% endfor %} </select> code: <input type="text" name="code"><br> code_2: <input type="text" name="code_2"><br> name: <input type="text" name="lname"><br> <input type="submit" … -
Images database schema
I'm trying to store user profile pictures, uploaded images in statuses, etc. on my site. When the user uploads a profile picture, there should be 3 types of the same image (Original image, medium sized, small sized). This is stored in the filesystem. A user can upload a maximum of 2 pictures in their statuses and each of these images follow the same types (original, medium, and small). The reason why I'm making different thumbnails of the same image is to serve those images depending on which screen display the user is accessing the site. That being said, what is the best way to store these image's file paths in my database? What kind of schema makes the best sense, or if there is another better way I can serve these images, what is the best approach? For the profile image table, I was thinking something like this: id user_id size img 1 2 S /img/s/avatars/ex.jpg 2 2 M /img/m/avatars/ex.jpg 3 2 L /img/l/avatars/ex.jpg Does this look like a good approach? -
