Flask mongoengine pagination

flask, mongodb, mongoengine, python

Solution

The `Pagination` object has an `items` list which will contain the mongoengine document objects (in your case the `Post` objects). This list can be iterated through to display the documents.

For example, in your template:

{% for post in posts.items %}
    {{ post.title }}
    {{ post.content }}
{% endfor %}

To get the actual page numbers for pagination links, use `iter_pages()`:

<div id="pagination-links">
    {% for page in posts.iter_pages() %}
        {{ page }}
    {% endfor %}
</div>

Both the documentation and the github link above, have a better example for pagination links:

{% macro render_pagination(pagination, endpoint) %}
    <div class=pagination>
        {%- for page in pagination.iter_pages() %}
            {% if page %}
                {% if page != pagination.page %}
                    <a href="{{ url_for(endpoint, page=page) }}">{{ page }}</a>
                {% else %}
                    <strong>{{ page }}</strong>
                {% endif %}
            {% else %}
                <span class=ellipsis>…</span>
            {% endif %}
        {%- endfor %}
    </div>
{% endmacro %}

Problem

I have a small Flask app which renders blog posts: views.py: ``` class ListView(MethodView): def get(self, page=1): posts = Post.objects.all() return render_template('posts/list.html', posts=posts) ``` This is all good, but I would like to add pagination to the `posts` object. Looking at the project docs, I see there is a pagination class. So I tried this: ``` class ListView(MethodView): def get(self, page=1): posts = Post.objects.paginate(page=page, per_page=10) return render_template('posts/list.html', posts=posts) ``` But now I get an error: ``` TypeError: 'Pagination' object is not iterable ``` So how do I iterate through my `posts` in the template?
