Django Filter Queryset Model
How can I filter my table to only show the quotes from a project. In order to display all quotes, I am using {% for quote in quotes.all %} Now, I would like to display quote relative to a site. Which means when selecting my site_id, I`ll be able to only see the quote relative to this site_id. I could write something like {% for quote in quotes.all %} {% if quote chantier.id %} {% endif %} {% endfor %} but this is wrong. Here is my model for quote: models.py class Quote(models.Model): name = models.CharField(max_length=30) site = models.ForeignKey(Site, on_delete=models.CASCADE) How can I display all quotes from this site? Many Thanks, -

Django dynamics colums forloop
I would like to know how you would solve my issue. I've managed a solution but aesthetically I don't like it I have a fix width box that I have to fill with a table (9 cols and 6 rows minimum). Some fields are fixed some others are dynamic. The results should be something similar to the following: | Order | <order_nr> | Qty | Desc | Price | Qty | Desc | Price | |----------------|--------------------|-----|------|-------|-----|------|-------| | Customer | | | | | | | | Address | | | | | | | | City | Zip code | | | | | | | | Shipping terms | Total order amount | | | | | | | | Note | <notes> | | | | | | | Qty Desc Price are dynamically generated based on the order that the customer has submitted, and potentially the order could have more than 10 lines (which my design is capable to handle) So here are my main problems and solutions: I have placed 2 tables together but I don't get the same line-height for both tables. I cannot add via CSS a fixed height since I don't know how … -
