Django, form hidden based on conditional statement
I'm new in django. I have the following models.py class Prodotto(models.Model): name = models.CharField() class Sottoprodotto(models.Model): prodotto=models.ForeignKey(Prodotto) name = models.CharField() class Lavorazione(models.Model): codice_commessa=models.ForeignKey(Informazioni_Generali) numero_lavorazione=models.IntegerField() prodotto=models.ForeignKey(Prodotto) sottoprodotto=models.ForeignKey(Sottoprodotto) And my forms.py class LavorazioneForm(forms.ModelForm): class Meta: model = Lavorazione fields = "__all__" A "Prodotto" element could have a "Sottoprodotto" or not. I want to have the possibility in my form (created utilizing crispy) to hidden the Sottoprodotto's box when a Prodotto don't have a Sottoprodotto related. It's possible? -
Not able to use django-storages to fetch static files
I am trying to use django storages to fetch static files for Django admin. I am facing a strange behavior that I am not able to understand clearly. I am having two different buckets, one for static files and other for some other purpose. If I comment out the AWS_S3_CUSTOM_DOMAIN keep everything else as it is (the way it is posted below), everything works. But if I uncomment AWS_S3_CUSTOM_DOMAIN and override the custom domain in my storage backend StaticStorage, it starts giving me 403. I know that I am missing something, just not able to figure out what. settings.py S3_BUCKET = os.environ.get('S3_BUCKET') S3_FILE_LOCATION = os.environ.get('S3_FILE_LOCATION') AWS_ACCESS_KEY_ID = os.environ.get('S3_STORAGE_ACCESS_KEY_ID', '') AWS_SECRET_ACCESS_KEY = os.environ.get('S3_STORAGE_SECRET_ACCESS_KEY', '') AWS_STORAGE_BUCKET_NAME = os.environ.get('S3_BUCKET', '') AWS_S3_CUSTOM_DOMAIN = f"{os.environ.get('S3_BUCKET', '')}.s3.amazonaws.com" AWS_S3_OBJECT_PARAMETERS = { 'CacheControl': 'max-age=86400', } AWS_DEFAULT_ACL = None AWS_S3_VERIFY = False AWS_S3_USE_SSL = False # s3 static settings STATIC_FILE_BUCKET = os.environ.get('STATIC_FILE_BUCKET') STATIC_LOCATION = 'static' STATIC_S3_CUSTOM_DOMAIN = f"{os.environ.get('STATIC_FILE_BUCKET', '')}.s3.amazonaws.com" STATIC_URL = f'https://{STATIC_S3_CUSTOM_DOMAIN}/{STATIC_LOCATION}/' STATICFILES_STORAGE = 'apps.utils.storage_backends.StaticStorage' DEFAULT_FILE_STORAGE = 'apps.utils.storage_backends.PrivateMediaStorage' storage_backends.py class StaticStorage(S3Boto3Storage): location = 'workflow' default_acl = 'private' def __init__(self, *args, **kwargs): kwargs['bucket'] = settings.STATIC_FILE_BUCKET # self.custom_domain = settings.STATIC_S3_CUSTOM_DOMAIN super().__init__(*args, **kwargs) -

Django Query Sets - Finding Percentage between two QuerySets
I have got two query sets - >>> region_carrier_groupby_total = <QuerySet [{'region_carrier': 'tc2 - rc2', 'DID_Count': 2}, {'region_carrier': 'tc1 - rc1', 'DID_Count': 16}]> >>> region_carrier_groupby_available = <QuerySet [{'region_carrier': 'tc2 - rc2', 'DID_Count': 1}, {'region_carrier': 'tc1 - rc1', 'DID_Count': 14}]> The objective here is to find the available percentage grouped by region_carrier for DID counts.

Django use a column as keys another as values and return dictionary
In Django I have a table within a model like: key value a 1 a 2 a 3 b 4 b 5 I would like to return: {'a': [1, 2, 3], 'b': [4, 5]} or: [{'key': 'a', 'values': [1, 2, 3]}, {'key': 'b', 'values': [4, 5]}] This can be done in Python easily by just iterating through all entries of the table. But since I discovered Aggregation | Django documentation | Django, I wonder if this can be done in Django directly, without writing Python loops? -

How to create dynamic route for file paths in flask app
In my application I have a file browser. The file names are urls for a detail page, wich takes as argument the bucket and the object name. @app.route("/object_info/<string:bucket_name>/<string:object_name>/", methods=["POST", "GET"]) def object_info(bucket_name, object_name): Like this: http://localhost:5000/bucket_name/Grain_08.tif/ This is working fine, but I cannot display the files in subfolders like in 1aaaa, because if I click to the 2. row the url is: http://localhost:5000/bucket_name/1aaaa/Grain_11.tif and so the url pattern for the object_info route is not working. I have tried solutions like optional routes, but the depth of the subfolders are not limited. Thats mean there can be a file in 4 subfolders. So I need some dynamic stuff so I can display the objects in the deeper folders. -

Django/Python3: Convert complex inner join query to

How do I get an AJAX callback function to render a Django url or html template with parameters?
I am a beginner and working on an app where I want to redirect the user to a checkout-basket (Django url via POST? Or render html template with variables?) after checking if anything is saved in localStorage. So I check that and use AJAX to send that data to my Django url in order to render that template passing on the variables in localStorage as JSON. But return render(request, "pizza/prebasket.html", context) in views.py doesn't work: even though the data is recieved, prebasket.html is not rendered. I read that that's because AJAX doesn't allow that and instead I need to post through AJAX's callback function. But how do I do that via POST and how do I pass on the parameters to my view or directly to my html template? (window.location.href only handles GET requests, so I guess that doesn't work). Here's my JavaScript and my views.py: function previous_selection () { if (localStorage.getItem("preselection") != null) { const data = new FormData(); data.append("preselection", preselection); const request = new XMLHttpRequest(); request.open('POST', '/prebasket'); const csrftoken = getCookie('csrftoken'); request.setRequestHeader("X-CSRFToken", csrftoken); console.log("DATA IS: ", data); request.send(data); console.log("PRESELECTION IS: ", preselection); request.onload = () => { // HOW DO I CALL MY URL WITH PARAMETERS HERE? }; … -

Django form containing different types of fields
I'm wanting to add a MultipleChoiceField with a CheckboxSelectMultiple widget to a model/form containing other types of input. I am wondering how I can do this and add classes to the entire MultipleChoiceField as well as classes to each of the choices (for bootstrap). I have tried adding a class to the whole MultipleChoiceField using: preferred_subjects.widget.attrs.update({'class': 'form-control'}) but it doesn't work. Even if it did, I also want to add classes to each of the options, but I am unsure how. I usually output forms using {{ form|crispy }} but since I want to add classes to each of my MultipleChoiceField options im guessing i'll need to use {% for option in fieldset %} and add classes as each is output. But the problem is I have other types of input in that same form which I don't want to add the class names to.
