python - Django 脆皮表格 : Set rows for Text Area

Question

使用 FormHelper() 创建表单时，我的表单的文本区域(对于 TextField s)太大:它们设置为 10 行。我想设置行数。我怎样才能做到这一点？
我的代码:models.py :

from django.db import models

class Spam(models.Model).
    ham = models.CharField(max_length=10, blank=True, null=False, default='Some ham')
    eggs = models.TextField(blank=True, null=False, default='', verbose_name="Lots of eggs")

forms.py :

from django import forms
from crispy_forms.helper import FormHelper
from crispyy_forms.layout import (Layout, Row, Column)

from .models import Spam

class SpamForm(forms.ModelForm):
    class Meta():
        model = Spam
        fields = ('ham', 'eggs')
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.helper = FormHelper()
        self.helper.form_method = 'POST'
        self.helper.layout = Layout(
            Row(Column('ham', css_class='form-group col-12')),
            Row(Column('eggs', css_class='form-group col-12')),
            # HERE: How can I set the rows for the text area widget?
        )

结果 HTML:

<!-- (ommited for brevity)  -->
<div  class="form-row " > 
  <div class="form_group col-12"  rows="2">
    <div id="div_id_eggs" class="form-group">
      <label for="eggs" class="">Lots of eggs</label> 
      <div class=""> 
          <textarea name="eggs" cols="40" rows="10" class="textarea form-control" id="eggs"></textarea> 
          <!--                            ^^^^^^^^
          <!--                            THIS is what I'd like to change to "2" -->
      </div>
    </div> 
  </div>
</div>
<!-- (ommited for brevity)  -->

Answer 1

您可以通过传入行来直接使用脆皮形式“覆盖”行:

Row(Column('eggs', rows='2', css_class='form-group col-12')),

或与字段:

Field('eggs', rows='2')
