Django: form is valid but is not save because no module named app is found
I'm developing a simple form to upload files. I see that my form is valid because some print statments I've made, however I'm getting an error when saving the form. ModuleNotFoundError at /admineditorial/predica/add/ No module named 'app' And: Exception Location: <frozen importlib._bootstrap> in _find_and_load_unlocked, line 965 I don't think it has to do something with Bootstrap.

Is it possible to include a ForeignKey inside a JSONField schema? How else can I effect this?
I am building an app in Django that allows users to build their own forms and in effect customise dynamic models. After much research, I've decided to effect this through Django, PostgreSQL and JSONFields where one model holds the schema and another holds the record data: class = Template(models.Model): schema = JSONField(null=True) # Schema for the form/model class = DynamicModel(models.Model): data = JSONField(null=True) # Corresponding data for the form/model template = models.ForeignKey(Template, null=True, blank=False, on_delete=models.SET_NULL) This means users can define their own model templates and I can hold different records using that template in another model. The idea is to parse the template.schema JSONField to display editable forms using jQuery and to store the output as dynamicmodel.data JSONField. Validations are passed on the client side. However, this comes with the drawback if I want to allow users to include ForeignKey lookups in their models. For example, say they wanted to add a choice box that offered selections from different customer.ids in a Customer(models.Model) class. Without hardcoding the ForeignKey directly into the DynamicModel class (which would defeat the point of the exercise) can you think of a way I can achieve this? -

Indexing product list takes way too long with Django, Haystack and Whoosh
I'm experiencing issues indexing a list of products (about 280k) with Haystack and Whoosh. It seems to take more than 28 hrs to run the update of the index.

Django paginator not responsive on last page
Iterating over a large QuerySet doesn't seem to be a viable option in Django 2.0 anymore. I've tried to speed it up using Django's own Paginator. def read_from_db_4(): paginator = Paginator(DataSet.objects.filter(status_id=1).order_by('id'), 1000) l = [] print("{} iterations!".format(paginator.num_pages)) for page in range(1, paginator.num_pages+1): l = l + list(paginator.page(page).object_list) print("{}, next page...".format(page)) return l This little function is reasonably quick but will stop on the very last page. I can also not get to the length of this page: len(paginator.page(LASTPAGE).object_list) this will just hang forever. I can get the length of all other pages previously. What's the reason for this odd behaviour? -
How to run a FOR loop on a JSONField in Django referring to specific elements

How to create, store and access user-defined forms in Django?
I am designing a basic workflow system that allows one user to fill in a form and pass it to another for approval. This is quite easy if I use static models that are pre-configured in models.py; you simply add a new record for each submission with a field designating the status and a few if functions. However, if I want to allow users to design their own forms (i.e. change the number and type of fields they might use), what's the best way of doing this? I still want to be able to identify each form submission as a separate record and to access individual values specific to fields in the forms. For example, lets say a user wanted to define the following "dynamic" fields in a model: CharField 1 DateField 2 FileField 3 I thought maybe one approach could be to use PostgreSQL and an ArrayField; set some constants for the record (e.g. ID and Status) and then store these dynamic fields in the array. However at this point I am stuck; how can I also store the values these fields have and access them as objects (e.g. if I want to display specific values in a template … -
