Sanity and validation of a raw html form created in django template
I have an Attendance model which basically stores attendance status of an employee of a department for a date. A supervisor marks the attendance of all the employees of a department for a date in one go. So to allow this, I render a list of all the employees of a department in a table and for each of them have a checkbox which represents Present/Absent status and a textbox that stores reason for absence. As I figured out there are 2 ways to do this : Formset Raw html forms in template with manually writing input elements. I implemented the functionality using the 2nd option (since I didn't have much control over the layout while using Formset) in which : I use request.POST.get('date') to get the date user inputs then request.POST.getlist('employees[]') to access the user ids of employees being selected and only for these employees I access the value entered in Reason text box using request.POST.get(''). It works fine mostly. But I have a few questions about this approach : Given that all user input is evil, is this a secure way since I am accessing raw input text data user entered using the request.POST dictionary. How do I … -

How to Import Another Python 3 File in Django Settings.py?
I'm using Python 3. I have two Python files in the same directory: first.py and second.py. In the beginning of first.py, I use: from second import * However, it returns the following error message: ModuleNotFoundError: No module named 'second' How should I import it in first.py? Update: To clarify my specific use-case, I am trying to split my settings.py in Django. I have a main settings.py file and another one that only includes the confidential information. I followed this following documentation that uses the following line in settings.py: from settings_local import * Note that settings_local.py is in the same directory. However, it returns the following error message: ModuleNotFoundError: No module named 'settings_local' I know the document says "Some of the examples listed below need to be modified for compatibility with Django 1.4 and later." but I do not know how to use it in Python 3. -
Django update only blank rows in model instance
I'm looping through a list of dicts and creating models (journals) from dicts. They have a many to many relationship with Researcher. Each dict looks like this {'abbreviation': 'Front. Artif. Intell. Appl.', 'journal_type': 'k', 'title': 'Frontiers in Artificial Intelligence and Applications'} However, there are duplicates in this list, which is fine, I check manually to see if they exist, if they do, I dont create a new model for it. BUT. The problem is, the entries in the list of dicts has duplicates with varying degrees of missing columns. Eg, Entry 123 {'abbreviation': 'Front. Artif. Intell. Appl.', 'journal_type': 'k', 'title': 'Frontiers in Artificial Intelligence and Applications'} Entry 124 {'abbreviation': 'Front. Artif. Intell. Appl.', 'issn':123 'journal_type': 'k', 'title': 'Frontiers in Artificial Intelligence and Applications'} As you can see, 124 is more 'complete' than 123. At the point of 123, I've already created the journal object from that hash. However, I want to update the same row with only the new fields from 124 (in this case, update the row with the issn) What is the proper way to do this? :) -
Ubuntu 16.04 Django 1.11.5 virtualenv opencv
I'm new to Ubuntu and also fairly new to web development, so I am hoping there is some obvious thing I am missing. My problem is as follows, I have a box running Ubuntu 16.04 I have my Django project with a virtualenv I used (with the virtualenv activated) pip install opencv-python, and it seemed to work all the files seem to be where I would think they need to be (env/lib/python3.5/site-packages/{cv2,numpy}). BUT when I run a manage.py command I get an error in the init.py (so it is finding the opencv package) of "ImportError: libSM.so.6: cannot open shared object file: No such file or directory". I get the same error when I enter python in the virtualenv and try to import cv2. You can see the error here Is .cv2 in the error a namespace? Is there an way I can get more information or do a python search for the namespace? -

Django-autocomplete-light & QuerySetSequence - getting the name of the original model for each QuerySequenceModel
I have 3 models from cities_light: City, Region and Country. I'm using QuerySetSequence with Django-autocomplete to create a queryset involving all 3 of these models, so that a user can type in one search bar to search for all types of location. I have things working but my current implementation feels very hacky, so I'm looking to see if there's a better way of doing this. As far as I can tell, while QuerySequenceModel inherits all the attributes of the relevant model (in this case, either City, Region or Country), it doesn't have an attribute that simply returns the name of the model it's inheriting from. So, the only way I can see of actually determining which model a QuerySequenceModel is to rather naively check to see whether it contains any defining attributes that uniquely identify it as either a City, Region or Country. Thus: for queryset in locations.query._querysets: if not hasattr(queryset.model, 'country'): profile.favourite_countries = queryset elif hasattr(queryset.model, 'region'): profile.favourite_cities = queryset elif hasattr(queryset.model, 'country'): profile.favourite_regions = queryset This works, but is hardly elegant, and also needs additional hacking in order to be fully functional (i.e. recognizing when one location type isn't present). For reference, here is the full list … -
How do I create and submit a form from a model inside a modal?
In my app I needed to add a form created from a model so I can add and edit records in my database. I did it in the following way to render the form in a separate page.: 1) I created a forms.py file: from django import forms from store_app.models import Product class AddNewProductForm(forms.ModelForm): class Meta: model = Product fields = ["title", "description", "weight", "price"] # Fields from my model class EditProductForm(forms.ModelForm): class Meta: model = Product fields = ["title", "description", "weight", "price"] # Fields from my model 2) Then I created the html template to display the form, edit_product.html: {% extends "store_app/base.html" %} {% load static %} {% block title %}Edit Product{% endblock %} {% block content %} <h1>Edit Product</h1> <form method="POST"> {{ form.as_p }} {% csrf_token %} <input type="submit" class="btn btn-primary" value="Submit!"> </form> {% endblock %} 3) After that, I added the following to my app's views.py: from store_app.models import Product from store_app.forms import EditProductForm from django.shortcuts import render, get_object_or_404 def index(request): return render(request, 'simple_app/main.html') def edit_product_view(request, id): instance = get_object_or_404(Product, id=id) form = EditProductForm(instance=instance) if request.method == "POST": print("POST") form = EditProductForm(request.POST, instance=instance) if form.is_valid(): form.save(commit=True) return index(request) else: print("ERROR FORM INVALID") return render(request, 'simple_app/edit_product.html', {'form': form}) …
