How to update user as an admin in djoser django?
My problem is that I want to change user status from admin panel. Admin should be able to change field "is_staff" from his panel. When I read the documentation, it says: User Use this endpoint to retrieve/update the authenticated user. Default URL: /users/me/ https://djoser.readthedocs.io/en/latest/base_endpoints.html#user Okay, and I am planning to use it to change user's password later, but it makes sense to change users password while being logged in as this user. But how to change another field ('is_staff') in another user while being logged in as admin? Does sending request to /users/me/ make sense? I will update this with any code needed. -

reference a HTML tag with javascript that was generated from django json schema
i am trying to reference a HTML tag that is generated by a django's django_jsonforms link JSON Schema link via javascript to dynamically update the form. For example 2 dropdowns in a form, if you make a selection in the 1st dropdown the 2nd dropdown should update. I've done this for HTML selection tags that i manually typed out but i am trying to get this to work for HTML generated by JSON Schemas. Here is what i've tried: inspect HTML page and try to call the tag by name with var project_selection = document.getElementsByClassName("form[project]")[0]; this didnt work, which i was a little surprised by since i see when i inspect the page that the select tag has name="form[project]" then i thought maybe the JSON Schema renders the tag after the javascript runs so i tried adding defer into my <script defer> and that didnt work i tried using JSON Schema $id #anchor and $ref but none of those worked to reference the tag by ID I am sure someone has come across this before so i hope this is an easy answer. At the end of the day i know i need to use the following with the JSON … -
Django UUID Validation Error: Sometimes object, sometimes UUID
This page is supposed to show a post for a social media website. Within <div class="is-flex">, I have an if/else/endif block for showing a like/unlike button. As the code is right now, it successfully shows the like/unlike button on non-shared posts. I would like to have it so the like/unlike button appears on all posts as long as {user.is_authenticated} is true, but if I move the like/unlike code block anywhere else in the div, I get this error. Even adding the line for the button and commenting it out gives the error. No variables are being written, only read, so I don't know why Django would get the UUID in one instance and the entire post object in another instance. Lines with *NOTE* comments are lines I tried duplicating/moving the like/unlike code block to without success. {% extends 'base.html' %} {% block title %}Home{% endblock %} {% block content %} {% #header user=user %} {% /header %} {% load crispy_forms_tags %} {% load markdown_extras %} {% load url_check %} {% load comment_like %} {% load post_like %} <main> <div class="is-flex mt-3"> <small>Posted by: <a href="/author/{% valid_url_profile post.author.id %}">{{post.author.displayName}}</a></small> <small> &nbsp;• {% load tz %} {% localtime on %} <small>Created: {{post.published}}</small> … -

Constrain unique_together could have conflict with the unique_field in dajngo Class
Basically, I would like to know if there is any conflict using the constrain unique_together as well as the parameter unique=true in one of the fields that belong to the array of the unique_together. it´s because I can´t remove the parameter unique=true of my field because it´s used as a foreigner key in another model. class User(AbstractUser): # User information fiscal_number = models.CharField(max_length=30,unique=True) phone = models.CharField(max_length=15, null=True) email = models.EmailField(max_length=254, verbose_name='email address') class Meta: unique_together = ['fiscal_number', 'email'] As you can see the goal is to make the combination of the fields fiscal_number and email unique -

Patch request not patching - 403 returned - django rest framework
I'm trying to test an API endpoint with a patch request to ensure it works. I'm using APILiveServerTestCase but can't seem to get the permissions required to patch the item. I created one user (adminuser) who is a superadmin with access to everything and all permissions.

I have setup the python debugger in the test, and I have tried actually going to http://localhost:xxxxx/admin/ in the browser and logging in manually with any user but the page just refreshes when I click to login and I never get 'logged in' to see the admin. I'm not sure if that's because it doesn't completely work from within a debugger like that or not. My test looks like this (using the Requests library): def … -
My pyrogram app don't start in Django framework view function, but in isolated module it works very well

How to modify the pdf in the server, django
Good dat to all. I have a django project running in a linux server with apache2. What my code does is to replace a PDF file. When the user fills the form, it is received, then replace the corresponding fields in the file and save() it. Locally it works perfectly, but when I try it on the server, the pdf is not overwritten because it always displays the same PDF instead of the modified one. Since locally works correctly, I thought it would be maybe the routes, or the permissions. The first option i already checked the routes, they are correct, so it must not be that. The other thing that can be not letting to overwrite, are the permissions so what I did, was to give permissions chmod 777 to the PDF file to see if it works, but it didnt. It still the file doesn't change. This code is to add the corresponding fields to the pdf def generate_attached_standard_pdf(attachment_data): try: name=attachment_data['creditor'] w, h = letter # DEFINE PDF CONFIGURATIONS c = canvas.Canvas('anexoA.pdf', pagesize=letter) c.setTitle('Anexo {}'.format(name)) pdfmetrics.registerFont( TTFont('Lato', BASE_DIR +"/recursos/fonts/Lato-Regular.ttf"), ) pdfmetrics.registerFont( TTFont('Lato-Bold', BASE_DIR+"/recursos/fonts/Lato-Bold.ttf"), ) c.save() return { 'success': True, 'message': 'PDF CREADO' } except Exception as e: print(e) … -

Creating migrations for a Django project that does not have any migrations already
I am working for a client with a 13 year old Django project. When they built the project migrations were not implemented so the project currently lacks migrations. I have tried creating migrations and then doing a datadump and loaddata into a new database to test them out. I am running into all sorts of errors and would like to start fresh. So my question is this. What steps should I take to implement migrations in the project so that we can move forward using migrations? The django version has been updated to 3.0.5 and there are a number of GenericForeignKeys used, which might make this extra tricky. When creating the migrations originally I was told to use the fake tag but don't completely understand what this means. Any help in the steps that I should take would be appreciated. For the sake of privacy/security for the client I don't want to just share a ton of their code but can share parts of it if it helps someone determine the steps that I should take.
