Heroku push fails because it can't find module allauth

Creating a ContentVersion in Salesforce from Django Application
I have some InMemoryUploadedFiles that users uploaded to my Django application. I need to pass these files' data encoded with base 64 as the VersionData when creating a ContentVersion object in Salesforce. If I pass in sample data such as fileData = base64.b64encode(b"testing"), everything works. The problem is trying to read/encode the data from Django's InMemoryUploadedFile If I pass in base64.b64encode(files[file].file.read()) as the VersionData (files[file] is the InMemoryUploadedFile - I'm looping through each one), it gives me the "bytes object is not JSON serializable" error. If I pass in the string version of that: str(base64.b64encode(files[file].file.read()), then the file gets uploaded but the contents are gibberish (aka a string of bytes). How do I format my InMemoryUploadedFile in such a way that I can pass the file's contents to the REST API call properly? More full code if it helps: def postFilesToDB(self, docRecords, files): payloadDict = {'passport_picture': { "name":"Passport Picture", "path":"", "data": None}, 'teudat_oleh': { "name":" Teudat Oleh", "path":"", "data": None }, 'tzav_giyus': { "name":"Tzav Giyus", "path":"", "data": None }, 'teudat_boded': { "name":"Teudat Boded", "path":"", "data": None }, } docTypeToPayloadEntry = { 'Passport Photo Scan': 'passport_picture', 'Teudat Oleh/Zakaut': 'teudat_oleh', 'Teudat Oleh/Zakaut - LSP Countries': 'teudat_oleh', 'Tzav Giyus': 'tzav_giyus', 'Teudat Boded': 'teudat_boded' … -
Separate documentations for internal and external APIs (drf_yasg)
I have two set of APIs: Internals, which are used in our client applications which we develop in our team, And externals, which is used by our business partners. I want to have a single document page which by authentication, shows internals APIs to our developers, and external APIs to every other viewer. How can I do that? I use: Django, DRF, and drf-yasg. P.S: I know this question is very general, but I do not have any clue where to start. I only guess some settings in get_schema_view, my views, and URL patterns are needed. -

Manage ListView and CreateView on the same template: how to submit data and update listView without reloading the page?
I want user to be able to add new record form a page and the list of records, that would be on the same page above, be updated without reloading the page (see attached picture below) For now, solutions I've read are to pass queryset (to display the list of records) in the context of createview But this way, user will submit, and page reloaded, for each new records... As User may have to enter hundreds of records, it is not a satisfactory solution so, maybe I should use Ajax to post new records and update the list of records But I wonder if Django has an in-a-box solution to resolve this problem? -

How to traverse multiple models properly in my queryset?
These are my models for the roles management(please suggest if you have better idea for this modeling). The problem here I get is while filtering only the menus which are assigned for the users. currently all the menus listed for the logged in user. What I want is list only menus if user has either create, update, delete, view status True. How can I do this ? The process of role assignment is. create role with some name(e.g Admin) assign users to the role assign menus and menu rights(create.update..) to the role. At login of user, if user is assigned to any role then I want to display that role's all menus if any create,update status is True.

How to add custom view page to django admin?

MariaDB replacing MySQL in Django
I have a project that was built using MySQL 5.4. But now I witched to MariaDB 10.3. If I understand correctly, the pip package mysqlclient==1.4.6 should still work on the new Database. Indeed, almost everythings works without problems with MariaDB on the webserver. However, I'd like to use MariaDB in my developement environment aswell. I'm using WAMP for the MySQL DB. In the phpMyAdmin landing page, I have to choose between MySQL and MariaDB databases. How can I tell Django to go to the MariaDB section? If I ignore that and just run manage.py check, I get the following errors: MySQLdb._exceptions.OperationalError: (1049, "Unknown database 'sampleDBmariaDB'") ... ... django.db.utils.OperationalError: (1049, "Unknown database 'sampleDBmariaDB'") -

You are trying to add a non-nullable field '_response_rendered'; django-markupfield
Upon wanting to add some Markdown to a project, I've decided to install django-markupfield to serve this objective. The only thing is that I've installed my models and associated fields ahead of making this decision; now replacing a TextField with MarkupField. When attempting to make a migration to adjust for this, the following is brought up: You are trying to add a non-nullable field '_response_rendered' to answer without a default; we can't do that (the database needs something to populate existing rows). Please select a fix: 1) Provide a one-off default now (will be set on all existing rows with a null value for this column) 2) Quit, and let me add a default in models.py What would be an appropriate default value to add to the fields that will be prompting for such? I have never been too sure of this question in general when it comes to using Django as well, so clarification would be appreciated. https://github.com/jamesturk/django-markupfield class Question(models.Model): title = models.CharField(max_length=50) body = MarkupField( markup_type="markdown", escape_html=True ) dated = models.DateField(default=date.today) user_account = models.ForeignKey( 'users.UserAccount', on_delete=models.SET_NULL, null=True, blank=True, related_name="questions" ) tags = models.ManyToManyField(Tag, related_name='questions') objects = models.Manager() dateranges = DateRangeQuerySet.as_manager() status = QuestionStatusQuerySet.as_manager() class Meta: ordering = ['-dated'] … -

Python Django- How do I interact/handle an uploaded text file
I have python code that reads in a document and parses it through into key words. I'm new to Django, but I have a working project that the user uploads a document and that file is saved to a postgres database. I'm having a really hard time figuring out how combine this project with the python code; I don't understand how to take that upload file and and break it down into words. **What I'm desperate to understand:**is how a python script is added and applied in Django; and then take the returned output, pieces of the broken down text, can be stored under columns in a Postgres db. Similar to how a python code can read in a text file and split up it up into words and organize the words into columns in a pandas DB. I'm struggling a lot with applying this function in a django context. I'm not sure if it would be easier to apply a python script to the UploadFile.object or apply the python functions after form is validated. I'm having a hard time finding an explicit example of this. I would greatly appreciate if anyone could shed some light on this! code: import … -
