ValueError：查看函數沒有返回響應

Question

我嘗試測試我的燒瓶的編輯路線應用但是得到這個錯誤我認爲這個錯誤通常是因爲返回，即使我在我的編輯路徑中有一個返回我該如何修復這個錯誤謝謝？ 錯誤：

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)

您測試get請求，但在你看來，你僅post迴應：

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 

如果你想測試post要求你應該使用POST功能：self.client.post(url, data)

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)
