Question

我尝试测试我的烧瓶应用的编辑路线但是得到这个错误我认为这个错误通常是因为返回，即使我在编辑路线中有一个返回我怎么能修复这个错误谢谢？错误：

ValueError: View function did not return a response

view.py：

@layout.route('/edit/<int:id>', methods=['GET','POST'])
def edit(id=None):
      user = Users.query.get_or_404(id)
      form = LoginForm(obj=user)
      if request.method=='POST':
          if form.validate_on_submit()== True:
             form.populate_obj(user)
             db.session.commit()
             flash("You have been updated the profile")
             return redirect(url_for('layout.user',page=1,sortby='normal'))

          else: #If the form does not have all fields that are required 
                return render_template('edit.html', form=form, id=id )

test.py：

def test_edit(self):
        u = Users(name='user1', email='user1@gmail.com', age=25)
        db.session.add(u)
        db.session.commit()
        data = dict(name='admin', email='adminu@gmail.com', age=28)
        db.session.commit()
        response = self.client.get('/edit/1', follow_redirects=True)
        self.assertTrue('You have been edit the profile', response.data)

您测试了get个请求，但在您的视图中，您仅对post做出回复：

 if request.method=='POST':
          if form.validate_on_submit()== True:
             ... # form valid logic
             return redirect(url_for('layout.user',page=1,sortby='normal'))

          else: # invalid post form logic
                return render_template('edit.html', form=form, id=id )

 return render_template('home.html) # get logic

如果您想测试post请求，请使用帖子功能：self.client.post(url, data)

实施例

def view_code():
   if request.method=='POST':
      if form.validate_on_submit()== True:
            user.name = form.user_name
            user.age = form.age
            user.email = form.email
            db.commit()
            ... # other form valid logic

def test_edit(self):
    response = self.client.post('/edit/1', data={'user_name': 'admin', age='28', email='adminu@gmail.net')
    self.assertTrue('You have been edit the profile', response.data)

ValueError：View函数未返回响应
