如何启用对所有字段的部分搜索？

Question

想象一下，我有以下 filters.py：

class ActionFilter(django_filters.FilterSet):
    class Meta:
        model = Action
        fields = "__all__"

现在，我想在我的模型中启用对 Charfield 字段的部分搜索。如何启用？

编辑

class ActionFilter(django_filters.FilterSet):
    name = django_filters.CharFilter(field_name = 'name', lookup_expr='icontains')
    description = django_filters.CharFilter(field_name = 'description', lookup_expr='icontains')
    class Meta:
        model = Action
        fields = "__all__"

HTML：

        <div class="card-body">
            {% load django_tables2 %}
            {% render_table table %}
            {% if table.filter %}
                <form action="" method="get" class="form form-inline">
                    {% bootstrap_form table.filter.form layout='inline' %}
                    {% bootstrap_button 'filter' %}
                </form>
            {% endif %}
        </div>
    </div>
</div>

tables.py 将 django_tables2 导入为表

from .models import Action, ControlTest
from .filters import ActionFilter

class actionTable(tables.Table):
    action_report = tables.Column(accessor='report.type')
    title_report = tables.Column(accessor='report.name')
    date_report = tables.Column(accessor='report.date')
    business_unit = tables.Column(accessor='bu.name')
    wallet_holder = tables.Column(accessor='control.bu')
    owner = tables.Column(accessor='owner')
    title_finding = tables.Column(accessor='actionr')
    description_finding = tables.Column(accessor='actionr.description')
    

    class Meta:
        Action.filter = ActionFilter
        model = Action
        fields = ('id', 'action_report', 'title_report', 'date_report', 'due_date','priority','business_unit', 'wallet_holder', 'owner', 'delegate', 'reviewer1', 'reviewer2', 'title_finding', 'description_finding','Action_Comments',
        'name', 'description', 'ControlID', 'ReportID', 'BUid', 'UserID_as_ActionOwner', 'UserID_as_ActionOwner', 'UserID_as_Actionreviewer', 'Priority',
        'status', 'Action_History', 'Review_Comments', 'documentation', 'referencenumber')

你的问题对我来说不是很清楚（即你所说的部分是什么意思）。

但我认为您的意思是该字段是否包含您过滤的某些文本，即标题为“这是最好的例子”的 qs 中的“The”。如果这就是您要查找的内容，则需要使用i__contains。

title = django_filters.CharFilter(lookup_expr='icontains',field_name='title')
