Django repeated forms
I have a form with a dropdown select option with possible options of 1,2,3,4 or 5. Based on the user select option 'x', I render same form repeated 'x' many times. Upon submit, I try to fetch the data using following in my view userprofileForm(request.POST) but this fetches just the last entry or most recent entry and not all the 'x' entries. Here is the rough HTML for my rendered form. In this instance the user selects option 2 so the form has a div repeated 2 times. <form ... > <div> <label...> <input...> </div> <div> <label...> <input...> </div> </form> Upon hitting submit button, the view for registeration is triggered and like I explained above in the beggining doing userprofileForm(request.POST) does not fetch both the 2 entries but just the last one. How can this be fixed so I have all form data of both the divs and how do I access it? -

Database queries to 'new-database' are not allowed in this test
I have added a new database in my django project. Now I have run into issues with my test cases. I am keep getting this error message for every single of my test cases: Database queries to 'new-database' are not allowed in this test I have searched for this issue and the common solution comes down to adding databases = '__all__' or databases = {'default', 'new_database'} to the TestCase class But the problem is that now we have a lot of these test cases in my django application and a lot of corresponding TestCase based classes. So it does not fill right (specifically from the scale point of view) to add this databases = '__all__' declaration or whatever to every single class. Do we have any other and more proper solution for this issue? (After all why django needs to make transaction to new_database in all other test cases every single time that does not seem needed at all?) -

Django rest framework: many to many through model write-able
