python - 带有 flat=True 的 Values_list 仍显示括号

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 }}在我在views.py中的行中添加了flat=True后仍然显示括号，事实上它们停止显示括号，但仍然显示括号。我还尝试了named=True、named=bool、flat=bool。还尝试了值而不是values_list...

View .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)

如果有人知道如何修复它，请告诉我。 提前致谢!

Answer 1

values_list() 与 flat=True 返回一个值列表，因此您必须提取索引为 0 的值，因为您的查询似乎总是只返回一行:

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