Django脆皮表单提交按钮

Question

我试图用来Crispy Forms使表格看起来不错。我的内容如下forms.py：

from django import forms
from .models import Team
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Submit, Layout, Field
from crispy_forms.bootstrap import (
    PrependedText, PrependedAppendedText, FormActions)

class CreateTeamForm(forms.ModelForm):
    class Meta:
        model = Team

        fields = [ 'Project_name', 'Project_number'
                  ]

        helper = FormHelper()
        helper.add_input(Submit('submit', 'Submit', css_class='btn-primary'))

        helper.form_method = 'POST'

然后在我的views.py：

def create_team(request):
    if request.method == 'POST':
        form = CreateTeamForm(request.POST, request.FILES)
        if form.is_valid():
            form.save()
            return render('/teams/my_team.html',{''})
    else:
        form = CreateTeamForm()

    return render(request, 'teams/team_form.html', {'form':CreateTeamForm()})

最后在我的模板中：

{% extends "main/base.html" %}
{% load crispy_forms_tags %}
{% block content %}
    <div class="row">
        <div class="jumbotron">
            {% crispy form %}

        </div>
    </div>
{% endblock %}

但是，没有显示我调用的提交按钮。我已经阅读了这份简略的表单文档，但我似乎发现自己的实现没有任何问题。显示除提交按钮以外的所有内容。有任何想法吗？

Answer 1

您FormHelper应该是表单类的属性，而不是其Meta类的属性。突出部分代码：

class CreateTeamForm(forms.ModelForm):
    class Meta:
        model = Team

        fields = [ 'Project_name', 'Project_number' ]

    helper = FormHelper()
    helper.add_input(Submit('submit', 'Submit', css_class='btn-primary'))
    helper.form_method = 'POST'

Answer 2

这个解决方案对我有用

from django.forms import ModelForm
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Submit

class BillForm(ModelForm):
    def __init__(self, *args, **kwargs):
        super(BillForm, self).__init__(*args, **kwargs)
        self.helper = FormHelper()
        self.helper.add_input(Submit('submit', 'Submit', css_class='btn-primary'))
        self.helper.form_method = 'POST'

    class Meta:
        model = Bill
        fields = ('__all__')

您按照此示例在方法内定义助手__init__，然后将其放入模板中：

{% load crispy_forms_tags %}
{% crispy form %}

在你的观点/行动中你应该有类似的东西

form = BillForm()
