Python Development [Django]: Composite Search, JSONP, XSS Filtering

Keywords: Python Django JSON Database encoding

Combinatorial search

When doing background blogging, you need to do different searches according to the type of articles.

1. Simple implementation

Associated documents:

from django.conf.urls import url
from . import views

urlpatterns = [
    url(r'^index.html/$',views.index),
    url(r'^article/(?P<article_type>\d+)-(?P<category>\d+).html/$',views.article)
]

url.py

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        .condition a{
            display:inline-block;
            padding: 3px 5px;
            border: 1px solid black;
        }
        .condition a.active{
            background-color: brown;
        }
    </style>
</head>
<body>
    <h2>Filter condition</h2>


    <div class="condition">
        {% if kwargs.article_type == 0 %}
            <a href="/article/0-{{ kwargs.category }}.html" class="active">whole</a>
        {% else %}
            <a href="/article/0-{{ kwargs.category }}.html">whole</a>
        {% endif %}

        {% for row in article_type %}
            {% if row.id == kwargs.article_type %}
                <a class="active" href="/article/{{ row.id }}-{{ kwargs.category }}.html">{{ row.caption }}</a>
            {% else %}
                <a  href="/article/{{ row.id }}-{{ kwargs.category }}.html">{{ row.caption }}</a>
            {% endif %}
        {% endfor %}
    </div>

    <div class="condition">
        {% if kwargs.category == 0 %}
            <a class="active" href="/article/{{ kwargs.article_type }}-0.html">whole</a>
        {% else %}
            <a href="/article/{{ kwargs.article_type }}-0.html">whole</a>
        {% endif %}

        {% for row in category %}
            {% if row.id == kwargs.category %}
                <a class="active" href="/article/{{ kwargs.article_type }}-{{ row.id }}.html">{{ row.caption }}</a>
            {% else %}
                <a href="/article/{{ kwargs.article_type }}-{{ row.id }}.html">{{ row.caption }}</a>
            {% endif %}
        {% endfor %}
    </div>

    <h2>Query results</h2>
    <ul>
    {% for row in articles %}
        <li>{{ row.id }}-{{ row.title }}------[{{ row.article_type.caption }}]-[{{ row.category.caption }}]</li>
    {% endfor %}
    </ul>
</body>
</html>

article.html

Note: Implementing this function is not difficult, the most important thing is to clarify the ideas in it. First, we should determine the url access path format http://127.0.0.1:8000/article/0-0.html, the first 0 represents the article_type field, the second 0 represents the category field, if it is zero, it means searching all the information in this field, confirming this is the first step of success, processing the document has a search place. The second key point is to generate the dictionary search_dict for relevant search, if 0 means all search; the third key point is also a very clever way to pass the parameter kwargs to the front end again, which is absolutely magical! ___________

Because the ArticleType type is the data that the blog is destined to die, it will not change later. It can load the data into memory to speed up the query speed.
