将几个动作分解为多个视图函数

如何解决将几个动作分解为多个视图函数

| 我有一个大视图功能，用户可以在其中添加，编辑，删除和更新他的知识。我目前正在一个视图中进行所有操作，因为我还没有学会如何按功能拆分视图。这是我目前拥有的- 我有一个指向视图的网址-

url(r\'^profile/edit/education/$\',\'views.edit_education\',name=\'edit_education\')

这是我的模型/模型形式-

class Education(models.Model):
    school = models.CharField(max_length=100)
    class_year = models.IntegerField(max_length=4,blank=True,null=True,choices=YEAR)
    degree = models.CharField(max_length=100,blank=True)
    user = models.ForeignKey(\'UserProfile\')

class EducationForm(ModelForm):    
    class Meta:
        model = Education
        exclude = (\'user\',)    

这是我的看法-

@login_required
def edit_education(request,edit=0):
    \"\"\"
    In the edit profile page,allows a user to edit his education
    and add multiple school entries.
     \"\"\"
    profile = request.user.get_profile()
    education = profile.education_set.order_by(\'-class_year\')   # for the template. display all eduation entries
# unindented for legibility
if request.method == \'POST\':

    if \'Add School\' in request.POST.values():
        form = EducationForm(data=request.POST,request=request) # passing request to form to do validation based on request.user
        if form.is_valid():
            new_education = form.save(commit=False)
            new_education.user = profile
            new_education.save()
            return redirect(\'edit_education\')

    if \'Delete\' in request.POST.values():
        for education_id in [key[7:] for key,value in request.POST.iteritems() if key.startswith(\'delete\')]:
            Education.objects.get(id=education_id).delete()
            return redirect(\'edit_education\')

    if \'Edit\' in request.POST.values():
        for education_id in [key[5:] for key,value in request.POST.iteritems() if value == \'Edit\' and key.startswith(\'edit\')]:
            edit = 1   
            school_object = Education.objects.get(id = education_id)
            form = EducationForm(instance = school_object,request=request)
        return render_to_response(\'userprofile/edit_education.html\',{\'form\': form,\'education\':education,\'edit\': edit,\'education_id\': education_id},context_instance=RequestContext(request))

    if \'Cancel\' in request.POST.values():
        return redirect(\'edit_education\')  

    if \'Save Changes\' in request.POST.values():
        form = EducationForm(request.POST,request=request,edit=1)
        if form.is_valid():
            Education.objects.get(id=request.POST[\'education_id\']).delete() # is there a way to update instead of delete and re-add?
            new_education = form.save(commit=False)
            new_education.user = profile
            new_education.save()
            return redirect(\'edit_education\')
else:
    form = EducationForm(request=request)
return render_to_response(\'userprofile/edit_education.html\',\'education\': education,},context_instance=RequestContext(request))

最后，我的模板-

<h3>Edit education info for {{user.get_full_name}}</h3> 

<form action=\".\" method=\"post\"> {% csrf_token %}
{% if education %}
{% for education in education %}
    <p><b>{{ education.school }}</b> {% if education.class_year %}{{ education.class_year|shorten_year}},{% endif %} {{ education.degree}} 
    <input type=\"submit\" name=\"edit_{{education.id}}\" value=\'Edit\' />
    <input type=\"submit\" name=\"delete_{{education.id}}\" value=\"Delete\" /></p>
{% endfor %}
{% endif %}

<table> 
<input type=\"hidden\" name=\"education_id\" value=\"{{education_id}}\" />
<tr><td>School:</td><td>{{form.school}}{{form.school.errors}}</td></tr>
<tr><td>Class Year</td><td>{{form.class_year}}{{form.class_year.errors}}</td></tr>
<tr><td>Degree:</td><td>{{form.degree}}{{form.degree.errors}}</td></tr>
<tr>{{form.non_field_errors}}</tr>
</table>

{% if not edit %}
    <p><input type=\"submit\" name=\"add\" value=\"Add School\" ></p>
{% else %}
    <p><input type=\"submit\" name=\"save\" value=\"Save Changes\" >
    <input type=\"submit\" name=\"cancel\" value=\"Cancel\" ></p>
{% endif %}
</form>

结局就在这里。如何使用单独的URL将视图中的这些操作之一分解为单独的视图函数？一个或两个例子就足够了。非常感谢您的帮助。     

解决方法

        一些想法： 您可以将一个大的html表单元素拆分为大块 您可以使用AJAX提交处理程序根据按下的提交按钮更改URL 您可以按照用户

Cerales

的建议进行操作，但是可以直接调用

add_school()

和其他方法来代替丢失POST数据的重定向，还可以将操作的字典映射映射到其处理程序：

action_map = {\'Add School\': add_school,...}

-这将消除条件链 您可以使用基于类的视图，该视图基本上是＃3的基于类的版本。 Django文档提供了基于类的通用视图 如果您愿意，我可以详细说明这些想法。 - 编辑： 通过评论回答您的问题：

from django.views.generic.base import View
class MySchoolView(View):
    def post(self,request,*kargs,**kwargs):
        if \'Add School\' in request.POST:
            return self.add_school(request,**kwargs)
        # (...)
    def add_school(self,**kwargs):
        # (...)

然后在urls.py中：

(r\'^schools/add/$\',MySchoolView.as_view())

请注意，以上内容未经测试，因此可能需要进行一些调整。

View

类源代码在这里。     ,        您可以通过两种方法来执行此操作。 这可能是您观点的一部分：

if request.method == \'POST\':

    if \'Add School\' in request.POST.values():
        return HttpResponseRedirect(\'/add_school/\')

然后，这可能是另一个视图的一部分，对应于ѭ11corresponding url：

def add_school(request):        
        if request.method==\'POST\':
        form = EducationForm(data=request.POST,request=request) # passing request to form to do validation based on request.user
        if form.is_valid():
            new_education = form.save(commit=False)
            new_education.user = profile
            new_education.save()
            return redirect(\'edit_education\')
