Django与HTML下form表单值的问题
这是我的后端部分
# form表单，判断用户输入类型
class RoomInfo(forms.Form):
roomnum = forms.CharField(
required=True,
max_length=10,
error_messages={
'required': "房间号不能为空",
'max_length':'长度不能超过10'
}
)
roomtype = forms.CharField(
max_length=10,
error_messages={
'max_length':'长度不能超过10'
}
)
maxnum = forms.IntegerField()
price = forms.IntegerField(
required=True,
error_messages={
'required': "价格不能为空"
}
)
facility = forms.CharField(
max_length=50,
error_messages={
'max_length':'长度不能超过50'
}
)
# 修改客房数据
def changeRoom(reqeust):
if reqeust.method =="POST":
data = RoomInfo(reqeust.POST)
if data.is_valid(): #输入信息合法
roominfo = data.clean()
room1 = Room.objects.get(roomnum = roominfo["roomnum"])
room1.roomtype = roominfo["roomtype"]
room1.maxnum = roominfo["maxnum"]
room1.price = roominfo["price"]
room1.facility = roominfo["facility"]
room1.save()
else:
err_msg = data.errors
return render(reqeust,"changeroom.html",{'room':data,'errors':err_msg})
return redirect("/app01/room")
else:
roomnum = reqeust.GET.get('roomnum')
room = Room.objects.get(roomnum=roomnum)
return render(reqeust,"changeroom.html",{'room':room})这是我的前端部分

<p>
房间号：{{room.roomnum}}
<input type="hidden" name="roomnum" value="{{room.roomnum}}">
<span>{{errors.roomnum}}</span>
</p>
<p>
房间类型：<input type="text" name="roomtype" value="{{room.roomtype}}">
<span>{{errors.roomtype}}</span>
</p>
<p>
最大居住人数：<input type="text" name="maxnum" value="{{room.maxnum}}">
<span>{{errors.maxnum}}</span>
</p>
<p>
价格：<input type="text" name="price" value={{room.price}}>
<span>{{errors.price}}</span>
</p>
<p>
设施：<input type="text" name="facility" value="{{room.facility}}">
<span>{{errors.facility}}</span>
</p>
<p>
<button type="submit" class="button">提交</button>
</p>
</form>
</body>
</html>我想实现检验通过form表单传值，现在第一次传值是成功的（即点击修改按钮后，如下图）
本意是测试如果用户输入数据不符合规范该提示处理，但在对应表单创建后故意输入错误数据，如最大居住人数输入中文“一”而不是数字，系统的确能正确判断错误，但其他部分产生了乱码
不是很了解HTML所以不知道发生了什么，请教一下是否有好的修改方法修改前端代码并能保证获取传来的值，还请各位帮帮忙
1.你把input value="{{}}"外面的引号去掉
2.给input加个结束<input value={{}} />
