python - 所有删除按钮都附加到第一行

问题描述

我有以下代码，它在行中显示一些数据，每个按钮都有“删除”按钮。

在我的情况下，“删除”按钮将始终删除列表中的第一行，即使我尝试删除中间的某些内容或结束列表中的最后一行，第一行也会被删除。

不确定为什么所有按钮在 FOR 循环中都与第一行相关联。

更新#1：我做了一些测试，我可以看到每个按钮都知道它自己的行的正确数据，但是在我点击按钮后，它会点击 data-target="#deleteLocation" 和这个新部分 "#deleteLocation"总是只知道第一行。

路线.py

@org_settings.route("/locations", methods=["GET"])
def locations():
    form = LocationForm()
    page = request.args.get("page", 1, type=int)
    locations = (
        Location.query.filter_by(user_id=current_user.id)
        .order_by(Location.name.asc())
        .paginate(page=page, per_page=5)
    )
    return render_template(
        "settings/locations.html",
        title="Locations",
        locations_tab="active",
        locations=locations,
        form=form,
    )

@org_settings.route("/locations/<int:location_id>/delete", methods=["GET", "POST"])
@login_required
def delete_location(location_id):
    location = Location.query.get_or_404(location_id)
    if location.organization != current_user:
        abort(403)
    db.session.delete(location)
    db.session.commit()
    flash("Your location has been deleted!", "info")
    return redirect(url_for("org_settings.locations"))

位置.html

        <tr>
            <th scope="col">Location Name</th>

解决方案

我通过将行 {{ location.id }} 的 ID 添加到 html 部分 data-target="#deleteLocation-{{ location.id }}" 的 ID 来解决它，如下所示

<button type="button" class="btn btn-danger btn-sm" data-toggle="modal"
                    data-target="#deleteLocation-{{ location.id }}">
                    <i class="bi bi-trash-fill" style="font-size:18px; color: rgb(255, 255, 255);"></i>
                </button>```

<div class="modal fade" id="deleteLocation-{{ location.id }}" data-backdrop=" static" data-keyboard="false"
            tabindex="-1" aria-labelledby="deleteLocationLabel" aria-hidden="true">
