如何在 Django 表單上填寫 label 字段？

Question

我試圖弄清楚如何 label 我的 Django 表單字段 - 目前我無法更改它們。 我曾嘗試在models.py 中修改字段名稱並添加標簽，但它會引發錯誤，我不確定在哪里添加它們。

模型.py：

from django.db import models
from django.contrib.auth.models import User


class Stats(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    date = models.DateField(auto_now=True)
    weight = models.DecimalField(max_digits=5, decimal_places=2)
    run_distance = models.IntegerField(default=5)
    run_time = models.TimeField()

    class Meta:
        db_table = 'health_stats'
        ordering = ['-date']

    def __str__(self):
        return f"You currently weigh {self.weight}, {self.user}"

視圖.py：

class UpdateHealth(View):
    
    def get(self, request, *args, **kwargs):

        stats = Stats
        update_form = StatUpdateForm
             
        context = {
            'stats': stats,
            "update_form": update_form,
            'user': stats.user,
            'weight': stats.weight,
            'date': stats.date,
        }
        return render(request, 'health_hub_update.html', context)
    
    def post(self, request, *args, **kwargs):

        stats = Stats
        update_form = StatUpdateForm(data=request.POST)
             
        context = {
            'stats': stats,
            "update_form": update_form,
            'user': stats.user,
            'weight': stats.weight,
            'date': stats.date,
            'run time': stats.run_time,
            'run distance': stats.run_distance
        }

        if update_form.is_valid():
            update_form.save()
            
        return render(request, 'health_hub_update.html', context)

forms.py：

class StatUpdateForm(forms.ModelForm):
    class Meta:
        model = Stats
        fields = ('user', 'weight', 'run_distance', 'run_time')

任何幫助，將不勝感激！

Answer 1

嘗試這個：

#forms.py 
class StatUpdateForm(forms.ModelForm):
    class Meta:
        model = Stats
        fields = ('user', 'weight', 'run_distance', 'run_time')

    def __init__(self, *args, **kwargs):
        super(StatUpdateForm, self).__init__(*args, **kwargs)
        self.fields['user'].label = "New user Label"
        self.fields['weight'].label = "New weightLabel"
        self.fields['run_distance'].label = "New run_time Label

或者

解決方案二：

將 label 屬性添加到字段。

#models.py

class Stats(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE, label="User Label"))
    date = models.DateField(auto_now=True, label="Date Label"))
    weight = models.DecimalField(max_digits=5, decimal_places=2)
    run_distance = models.IntegerField(default=5)
    run_time = models.TimeField()

Answer 2

試試這個，它適用於 django 4.1

class ProductForm(forms.ModelForm):

    class Meta:
        model = ProductModel
        fields = ('name', 'og_price', 'discount', 'sell_price', 'dis_pice', 'info', 'status', )

        

        labels = {
            'name':'Product Name',
            'og_price':'Original Price',
            'discount':'Product Discount',
            'sell_price':'Product Selling Price',
            'dis_pice':'Product Discounted Price',
            'info':'Product Information',
            'status':'Product Availability Status',
        }

By default in case of model forms The form field's label is set to the verbose_name of the model field, with the first character capitalized.

如果您想要對表單標簽進行任何自定義，您可以以字典形式傳遞標簽，其中鍵作為字段名稱，值作為 model 表單的 Meta class 中的自定義 label 值。

例如：

labels = {‘name’: ‘Enter Name’, ‘password’: ‘Enter Password’, ‘email’: ‘Enter Email’ } 

class StatUpdateForm(forms.ModelForm):
    class Meta:
        model = Stats
        fields = [‘name’, ‘password’, ‘email’]
        labels = {‘name’: ‘Enter Name’, ‘password’: ‘Enter Password’, ‘email’: ‘Enter Email’ }
