Question

我想在1个算法中添加所有列以进行搜索。如果可能的话。

这样的事情：

*更新* （我已更新views.py和search_table.html）它只是正确搜索url字段。我在这些字段中输入的id和标题将为我提供整个表格。

views.py

def search_table（request，pk）： table_name = Crawledtables.objects.get（id = pk） t = create_model（table_name.name）

q = request.GET['q']
if q is not None:

    query = t.objects.filter(Q(id__icontains=q) | Q(title__icontains=q) | Q(url__icontains=q))
    return render(request, 'search/results_table.html', {'tbl_name': table_name,
                                                         'details': query,
                                                         'query': q})

else:
    return HttpResponse("Please submit a search term!")

results_table.html

<strong> {{ tbl_name }}</strong>
    <p> You searched for: <strong>{{ query }}</strong></p>
    {% if details %}
        <p> Found {{ details|length }}</p>
    <div class="row">

        <table class="table table-bordered sortable">
            <thead>
            <tr>
                <th>Id</th>
                <th>Title</th>
                <th>Url</th>
            </tr>
            </thead>
                    <tbody>
            {% for lists in details %}
                <tr>
                    <td>{{ lists.id }}</td>
                    <td>{{ lists.title }}</td>
                    <td><a href="{{ lists.url }}" target="_blank">{{ lists.url }}</a></td>
                </tr>
            {% endfor %}
            </tbody>
        </table>
</div>

    {% else %}
        <p> No results found</p>
    {% endif %}

{% endblock %}

search_table.html

{% if tbl_name %}
    <form action="/search/{{ tbl_name.id }}/results" method="GET">
{% endif %}
<input type="text" name="q" placeholder="Id">
<input type="text" name="q" placeholder="Title">
<input type="text" name="q" placeholder="Url">
        <input type="submit" value="Search">
    </form>

更新

models.py

def create_model(db_table):
    class CustomMetaClass(ModelBase):
        def __new__(cls, name, bases, attrs):
            model = super(CustomMetaClass, cls).__new__(cls, name, bases, attrs)
            model._meta.db_table = db_table
            return model

    class AllTables(models.Model):
        __metaclass__ = CustomMetaClass

        id = models.IntegerField(primary_key=True)
        title = models.CharField(db_column='Title', blank=True, null=True, max_length=250)
        url = models.CharField(db_column='Url', unique=True, max_length=250, blank=True,
                               null=True)
        created_at = models.DateTimeField(db_column='Created_at')

    return AllTables

Answer 1

Q对象用于进行复杂的逻辑查询。

在语法中使用：AND（＆amp;）和OR（|）

from django.db.models import Q


t.objects.filter(Q(id__icontains=q_id) | Q(title__icontains=q_title) | Q(url__icontains=q_url))

django多个搜索词
