python - Django Crispy 表单提交按钮

Question

我正在尝试使用 Crispy Forms 使我的表单看起来不错。我的 forms.py 中有以下内容:

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 中:

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，我调用的提交按钮没有显示。我已经阅读了 cripsy 表单文档，我似乎无法发现我的实现有任何问题。显示除提交按钮以外的所有内容。有什么想法吗？

您的 FormHelper 应该是您的表单类的属性，而不是它的 Meta 类。缩减代码的那部分:

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'
