Shopify - How to exclude a collection in paginate? - shopify

Question

I need to exclude a collection inside the paginate loop. But if I use the conditional statement, it will still be counted in paginate count.
So If I paginate by 10 and there are 2 products from the excluded collection in first page, I will only see 8 products in first page.
Any solution for this? Here's my snippet:
{% paginate collection.products by 10 %}
<ul>
{% for product in collection.products %}
<!-- Check for collection -->
{% assign is_treatment = false %}
{% for c in product.collections %}
{% if c.handle == "salon-treatment" %}
{% assign is_treatment = true %}
{% endif %}
{% endfor %}
{% unless is_treatment %}
<li>{{ product.title }}</li>
{% endunless %}
{% endfor %}
</ul>
{% endpaginate %}
Note: This question is duplicated from the one I posted in Shopify forum.

Answer 1

What I did for something like this was first load in all the desired products into a collection of my own (basically an array of objects), and then paginate THAT array... so, if you write a function called exclude_some_products which returns all the unexcluded products, do this:
{% assign my_smaller_collection = exclude_some_products collection %}
{% paginate my_smaller_collection.products by 10 %}
<ul>
{% for product in my_smaller_collection.products %}
<!-- Check for collection -->
{% assign is_treatment = false %}
{% for c in product.collections %}
{% if c.handle == "salon-treatment" %}
{% assign is_treatment = true %}
{% endif %}
{% endfor %}
{% unless is_treatment %}
<li>{{ product.title }}</li>
{% endunless %}
{% endfor %}
</ul>
{% endpaginate %}
p.s. pardon my code, I'm not even sure what language this is!
