How do I include a Background picture in a css file for django usage?
I'm trying to include a background picture into one of my css files which is then loaded into a html file using djangos compressor module. The project looks as follows: djangoproject |-myproject (with setup.py etc) |-statics |-images |-css |-templates |-index.html In the index.html i used {% load static %} {% load compress %} {% compress css %} <link rel="stylesheet" href="/static/css/style.css"> {% endcompress %} and in this style.css, I would like to include a background picture from statics/images/bg.jpg. I tried to do this as follows: background: url('../images/bg.jpg') 50% 0 repeat-y fixed; but the picture wont appear. So does anyone know how to refere the url here? Because outside of django, this way works well. Thanks for any advie and sorry for my bad english skills (just ask if you are not able to understand something because of bad word choice etc.)! Thanks! -
Which one makes more sense, writing models in django or creating a table then auto-generating the models?
We have designed our ER diagram for our database design but I don't know if it makes more sense to write models in Django from scratch or create tables in Postgres then use inspectdb. What are the disadvantages of the latter and which one is most commonly used in projects? -
Store ALL Django errors in a Model?
I was wondering if there is a way to store every and all errors in a Django Model? Let's say I have a function that connects to an API and that API returns 404. Similarly, I have a model that people add their attendances to, if there's something wrong in a Model, it doesn't let the User proceed with what they're doing but I want it to log that error as well, not locally, but in a Model. Consider a model of a similar structure: class ErrorLog(models.Model): error = models.CharField(max_length=255) message = models.TextField() #Then date and time etc. I understand that for my function I'd need to use a try and except block but what would I do for the models to automatically log the error inside a model? -

Render different date format depending on time that passed - either |timesince or |date
Good morning. What I would like to achive is that when user posted sooner than 24h from now, I would like to have for example: Posted: 4h ago, but when it's more than 24h, it would be nice to have: Posted: November 10. First approach is doable by using: {{ post.date_posted|date:"F d, Y" }}, second one: {{ post.date_posted|timesince }}, but is there a way to "mix" them? Is is possible in Django? -

Django: Getting FieldError While Using Slug in URL
I am a beginner in Django. Right now, I am building an app, called PhoneReview. It will store reviews related to the latest mobile phone. It will also display phone brands, along with the associated phone models and their reviews. Right now, I am trying to use slug in URLs. I have successfully used slug in two of my templates, which are index.html and phonemodel.html. However, I am facing issues with the third template, which is details.html. When I go to http://127.0.0.1:8000/index, I see this page: When I click on Samsung, I see this page: Up to this is fine. But when I click on any phone model, like Galaxy S10, I get FieldError error. It looks like this: FieldError at /details/galaxy-note-10 Cannot resolve keyword 'slug' into field. Choices are: date_published, id, link, phone_model, review_article When I click on Samsung, I am supposed to see the details.html page, which has the review of the phone, along with the news link. Instead, I am getting the 404 error. Here are my codes of models.py located inside PhoneReview folder: from django.db import models from django.template.defaultfilters import slugify # Create your models here. class Brand(models.Model): brand_name = models.CharField(max_length=100) origin = models.CharField(max_length=100) manufacturing_since = … -

Django View Contained Within Template
This is hard to explain, but what I want to be able to do is have a search view which operates independently from all of my other views. I would like to have multiple templates with a search box embedded which will search and return results independent of the view that is being rendered. At the moment the only way I can think of to do this is to create a separate form instance for every single function based view. I would like to have the search self contained. Can someone advise me on what I need to look at to do this as I have no idea where to start. I was looking at class based vies, but I still can't separate the search function from the template. -

Use Rosetta on production site
We are looking for a way to help users translate our website. As developers, we sometimes edit the .PO files manually, but we also love Rosetta. The UI for Rosetta would also suit our translators. Is Rosetta also intended for use in a production environment by external users? Are there any examples of Rosetta running on a production site? If so, what strategy do you use to get the translations back into your repository? -

How to Sort a Django ListView on Button Click
I'm making a website which has a bunch of Event posts (Parties, Get-Togethers, Fundraisers etc.). I want the user to be able to sort the posts by the date those event posts were created (created_date) and by the date that event post takes place (start_date) on button click. There are exactly 2 ways the user can sort the ListView (by created_date or by start_date according to my models.py) so I want the button to be a toggle, where clicking it once would filter by start_date and clicking the button once more (after the page refreshes) would filter by created_date. My home.html contains the button and a for loop to show the posts: <!-- THE EVENT FEED --> <div class="feed"> <h2>Event Feed</h2> <!--BUTTON TO FILTER EVENT FEED--> <div style = "border-top: solid 1px #eee; width:100%;align-items: center;display: flex;flex-direction: column;"> <a href="{% url 'whsapp-home' %}?ordering={% if ordering == 'created_date' %}-start_date{% else %}-created_date{% endif %}"><button>Filter by Event Date</button></a> <!--<button data-text-swap="Filter by Event Date"></button>--> </div> <div class="chat"> {% for post in posts %} <div class="your messages"> <div class="message"> <b>{{ post.title}}</b> </div> </div> {% endfor %} </div> </div> And here is my class based view for the posts: class PostListView(ListView): model = Post template_name = 'whsapp/home.html' … -

Searching in Django, a few words in one object
I have an app where a user can look for recipes by inputing ingredients. I am wondering how to make it in query that django will know that "Juice of lemon" is one ingredient, now after inputing "Juice of Lemon" it shows as well "Juice of citron".
