Detailed introduction to flask paging

In the process of learning, we will encounter such a problem, that is, in the process of learning, we will find that paging is needed. Here, I will introduce to you the paging mentioned in the book.

@app.route('/',methods=['GET'])
@app.route(&#39;/<int:page>&#39;)
def home(page=1):
	pagination=Post.query.order_by(Post.publish_date.desc()).paginate(page, per_page=10,error_out=False)
	posts = pagination.items
	link,tuijian_post,fenlei=get_tui_link()
	return render_template(&#39;home1.html&#39;,
                           posts=posts,
                           pagination=pagination,
                           tuijian_post=tuijian_post,fenleis=fenlei,                
                           links=link)

This is the paginated data I read from the database. So how do we paginate? Let’s see what the book says

Then we need to use a separate page to save our paging related information.

{% macro pagination_widget(pagination, endpoint) %}
<ul class="pagination">
<li{% if not pagination.has_prev %} class="disabled"{% endif %}>
<a style=&#39;background-color: lightgoldenrodyellow;color: brown;&#39; href="{% if pagination.has_prev %}{{ url_for(endpoint,
page = pagination.page - 1, **kwargs) }}{% else %}#{% endif %}">
«
</a>
</li>
{% for p in pagination.iter_pages() %}
{% if p %}
{% if p == pagination.page %}
<li class="active">
<a style=&#39;background-color: lightgoldenrodyellow;color: brown;&#39; href="{{ url_for(endpoint, page = p, **kwargs) }}">{{ p }}</a>
</li>
{% else %}
<li>
<a style=&#39;background-color: lightgoldenrodyellow;color: brown;&#39; href="{{ url_for(endpoint, page = p, **kwargs) }}">{{ p }}</a>
</li>
{% endif %}
{% else %}
<li class="disabled"><a href="#">…</a></li>
{% endif %}
{% endfor %}
<li{% if not pagination.has_next %} class="disabled"{% endif %}>
<a  style=&#39;background-color: lightgoldenrodyellow;color: brown;&#39; href="{% if pagination.has_next %}{{ url_for(endpoint,
page = pagination.page + 1, **kwargs) }}{% else %}#{% endif %}">
»
</a>
</li>
</ul>
{% endmacro %}

So how do we use it

{% import "mac.html" as macros %}

Add the following

## after our loop

# The effect is as shown
