Question

嘿，我是Django的新手，我正试图在我的第一个网站上添加搜索栏。我的问题是，当我搜索我/用户输入的任何值并且在网站上时，该网站只会刷新并且不给我任何回报，但是当没有内容匹配时我给网站显示的空选项搜索。

（这不是所有的Topic模型）

model.py

class Topic(models.Model):

    content = models.CharField(max_length=200)

views.py

def search(request):
    query = request.GET.get('q')
    if query:
        result = Topic.objects.filter(content__icontains=query)
        context = { 'query': query, 'result': result}
        return render(request, 'learning_logs/topics.html', context)

（这就是所有topic.html，我很抱歉它如何变成了原来的topic.html上的样子，但这就是完整的topic.html）

topics.html

% extends "leaning_logs\base.html" %}
    
{% block page_header %}
    <h1>Topics </h1>
    <br><a href="{% url 'learning_logs:new_topic' %}">Add a new topic</a></br>
{% endblock page_header %}

{% block content %}

    <form method="GET" action="{% url 'learning_logs:search' %}">
        {% csrf_token %}
        <input name="q" value="{{ request.GET.q }}" placeholder="search..">
        <button class="btn btn-success" type="submit">
            Search</button>
    </form>

        {% for topic in topics %}
            <div class="card-mb3">
                <div class="card-header" style="background-color:lightgrey">
                    <table class="table">
                        <tr>
                            <th>Image</th>
                            <th>Title of the topic</th>
                            <th>Edit</th>
                            <th>Delete</th>
                        </tr>
                            <div class="card-body" style="background- color:white">
                               <tr>
                                  <td>
                                    {% if topic.image %}
                                <image src="{{topic.image.url}}" style="width:200px">
                            {% else %}
                                <span class="text-muted">No Image have been added</span>
                            {% endif %}
                        <td><h3>
                            <a href="{% url 'learning_logs:topic' topic.id %}" style="float:center">{{topic}}</a>
                        </td></h3>
                                
                        <td><small><a href="{% url 'learning_logs:edit_topic' topic.id %}">
                        <button method="submit" class="btn btn-primary">
                            Edit topic</button></a></small></td>
                            
                        <td><small><form method="post" action="{% url 'learning_logs:delete_topic' topic.id %}">
                        <button type="submit" class="btn btn-danger btn-primary" >
                        Delete topic</button></form></small></td>
                    </tr>
                </div>
                </div>
            </div>
        {% empty %}
            <h3><li>No topics have been added yet.</li></h3>
            
        {% endfor %}

{% endblock content %}

Answer 1

此：

{% for topic in topics %}

应该是：

{% for topic in result %}

搜索栏没有内容返回
