我用modelformset_factory制作了一个表单(实际上是Formset)。我用显示
<form method="post" action="">
{% csrf_token %}
{{ player_formset.management_form }}
{% for player_form in player_formset %}
{% for field in player_form %}
{{ field.label_tag }} {{ field }}
{% endfor %}
<br>
{% endfor %}
<input type="submit" value="Aggiungi">
</form>
当它自动渲染时，会添加一个写有"Human ptr:">的字段(因为我的模型Player是Human的子类……如果我直接使用Human，他会向我显示'Id:'，标题只是为了概括问题)。
我如何删除这封信？我试过了：
1) 在html文件中使用标签｛%forloop.last%｝，但实际上最后一个字段是"删除：">复选框(如果我使用can_Delete=False它有效，但我需要它)
2) 更改PlayerForm(ModelForm)Meta中的标签，但似乎不适用于此字段。奇怪的是，窗口小部件=｛'human_ptr'：输入(attrs=｛｝)｝，但它影响｛｛field｝｝而不是{field.label_tag｝}
如果有用的话，我添加所有相关代码的部分：
forms.py
from skeleton.models import Player
from django.forms import ModelForm
from django.forms.widgets import Input
class PlayerForm(ModelForm):
class Meta:
model = Player
fields = ['first_name', 'last_name', 'jersey_number']
labels = {
'first_name': 'Nome',
'last_name': '',
'jersey_number': 'Numero di maglia',
'human_ptr': 'human_ptr', }
# widgets = {'human_ptr': Input(attrs={})}
views.py
from django.shortcuts import render, redirect
from skeleton.models import Player
from django.contrib.auth.decorators import login_required
from .forms import PlayerForm
from django.forms import modelformset_factory
from django.http import HttpResponseNotFound
# Create your views here.
@login_required(login_url="/accounts/login/")
def team_area(request):
if request.user.team is not None:
PlayerFormSet = modelformset_factory(Player, form=PlayerForm, extra=1, can_delete=True,)
if request.method == "POST":
player_formset = PlayerFormSet(
request.POST,
request.FILES,
queryset=Player.objects.all().filter(team=request.user.team),)
for player_form in player_formset:
if player_form.is_valid():
player = player_form.save(commit=False)
player.team = request.user.team
if player_formset.is_valid():
player_formset.save()
return redirect('team_area:home')
else:
player_formset = PlayerFormSet(queryset=Player.objects.all().filter(team=request.user.team))
return render(request, 'team_area/team_area.html', {'player_formset': player_formset})
else:
return render(request, 'team_area/empty_page.html')
型号.py
class Human(models.Model):
SHIRT_SIZES = (('XXS', 'XXS'), ('XS', 'XS'), ('S', 'S'), ('M', 'M'), ('L', 'L'), ('XL', 'XL'), ('XXL', 'XXL'))
team = models.ForeignKey(Team, on_delete=models.CASCADE)
first_name = models.CharField(max_length=16)
last_name = models.CharField(max_length=16)
jersey_size = models.CharField(max_length=4, choices=SHIRT_SIZES, blank=True)
slug = models.SlugField(blank=True)
def save(self, *args, **kwargs):
self.slug = slugify(self.first_name + ' ' + self.last_name)
super(Human, self).save(*args, **kwargs)
def __str__(self):
return self.first_name + ' ' + self.last_name
class Player(Human):
year_of_birth = models.IntegerField(validators=[MinValueValidator(1900), MaxValueValidator(2100)], blank=True, null=True)
jersey_number = models.IntegerField(validators=[MinValueValidator(0), MaxValueValidator(99)], blank=True, null=True)
all_star_game = models.ForeignKey(AllStarGame, on_delete=models.CASCADE, blank=True, null=True)
可能我想直接修改表单(views.py)，而不是我显示表单的方式(team_area.html
它不漂亮，但可以
{% for field in player_form %}
{% if field.label_tag != id %}
{{ field.label_tag }} {{ field }}
{% endif %}
{% endfor %}
我在html文件中完成了这项工作。我必须添加其他内容，因为没有表单就无法使用
{% for field in player_form %}
{% if forloop.revcounter != 2 %}
{{ field.label_tag }} {{ field }}
{% else %}
{{ field }}
{% endif %}
{% endfor %}
