How to filter objects from template?

I have 2 models Category and Spending where Category is one of the Spending fields.

User can create custom categories and add spending on the webpage.

The question is, how to filter spendings by categories in Template?

I have:

{% for category in categories %}
    {% for spending in spendings %} 'I want this FOR have only spendings from this category.'

I know how to filter objects with Object.objects.filter() but I am not sure it applies here, because categories are dynamic here

You can do this way.

{% for category in categories %}
     {% for spending in category.spending_set.all %}
         {{spending}}
     {% endfor %}
{% endfor %}

Use the reverse relation. You haven't shown your models, but presumably there is a foreign key from Spending to Category. If so:

{% for spending in category.spending_set.all %}
