Question

所以我有这个html代码：

<legend><h1 > Weapons that this character has </h1></legend>
    <div>
        <ul style="list-style-type:none" >
            {% if request.GET.idChar %}
            <li >{{ charname }} Has Maihand {{ mh }} and Offhand {{ oh }}</li> 
            {% else %}
            <li>no</li>
            {% endif %} 
        </ul>


    </div>

问题是{{charname}}，{{mh}}和{{oh}}仍在我在views.py的一行中添加flat = True后仍显示括号，实际上，它们停止显示括号，但仍显示括号。我还尝试了named = True，named = bool，flat = bool。还尝试使用值而不是values_list ...

Views.py：

def character_weapons (request):
    idchar = request.GET.get('idChar')
    weapons = Characterweapons.objects.filter(characterid__exact=idchar).values_list('weaponid','categoryid_id')
    charname = Characters.objects.filter(characterid__exact = idchar).values_list('name', flat=True)
    print("charname: ")
    print(charname)
    if weapons[0][1] == 1:
        mh_id = weapons[0][0]
        oh_id = weapons[1][0]
    elif weapons[0][1] == 2:
        oh_id = weapons[0][0]
        mh_id = weapons[1][0]
    mh = Weapons.objects.filter(weaponid__exact=mh_id).values_list('weaponname', flat=True)
    oh = Weapons.objects.filter(weaponid__exact=oh_id).values_list('weaponname', flat=True)


    context={"mh": mh, "oh": oh,"idchar": idchar,"charname": charname}

    return render(request,'users/character_weapons.html', context)

如果有人知道如何解决，请告诉我。预先感谢！

Answer 1

values_list()和flat=True返回值列表，因此您必须提取索引为0的值，因为查询似乎总是只返回一行：

context={"mh": mh[0], "oh": oh[0],"idchar": idchar,"charname": charname[0]}

Answer 2

这是一个固定列表，但仍然是一个列表。如果要一次性输出，请使用|join过滤器。

{{ mh|join:"," }}

Flat = True的Values_list仍显示括号
