Django form表单修改数据

form：

#!/usr/bin/env python

#coding:utf8

from django.forms import Form,ModelForm

import models

class CourseModelForm(ModelForm):

    class Meta:

        model = models.Course

        exclude = ()

    def __init__(self,*args,**kwargs):

        super(CourseModelForm,self).__init__(*args,**kwargs)

        for fieldname in self.base_fields:  #循环给所有字段加样式

            field = self.base_fields[fieldname]

            field.widget.attrs.update({'class':'form-control'})

后端：

def mod_course(request,customer_id):

    print("进入修改课程")

    course_obj = Course.objects.get(id=customer_id)

    if request.method == 'POST':#使用form做数据修改

        form = forms.CourseModelForm(request.POST,instance=course_obj)#获取POST修改后的数据

        if form.is_valid():#判断是否满足form条件

            form.save()

        return redirect('/course/')

    print("customer_ID===========>",customer_id)

    print(course_obj)

    form = forms.CourseModelForm(instance=course_obj)

    return render(request,'course_mod.html',{'course_form':form})

前端：

{% extends 'index.html' %}

{% block head-menu %}

    <h2 style="margin-left: 5%">Course modified</h2>

        <form class="form-horizontal" action="" method="post">

            {% for field in course_form %}

                  <div class="form-group">

                    <label class="col-sm-2 control-label">{{ field.label }}</label>

                    <div class="col-sm-10">

                        {{ field }}

                    </div>

                  </div>

            {% endfor %}

        <input style="margin-left: 50%" class="btn btn-primary btn-rg active" type="submit" value="提交"/>

        </form>

{% endblock %}
