RE: Bug in Django 2.1 on ModelMultipleChoiceField

Looking at it, I would say that this is by design. You shouldn’t use an empty label on a multiple choice field. Perhaps this should be clarified in the docs. Saying that, if you really want an empty label on a multiple choice field, you could create your own class that initializes empty_label

You have to use "model_selection", it will work. Quite a while ago "cross_validation" has been replaced by" model_selection". For reference you can go through my code: https://colab.research.google.com/drive/1NliqtxZVvLhZNXhNFyXQZpwG392hcvh4 Do inform, in any case. On Wed, Mar 13, 2019 at 5:14 PM

Re: Need to Store All Model data in RAM

Hi Vaibhav, Andréas is right. You need to evaluate the queryset first as the orm queries are lazy. So the solution would be something like below example. another_list = [] getdata = data.objects.all() # this is a queryset # apply filters if you need to getdata = list(getdata) # this would be

Re: Need to Store All Model data in RAM

Hi, You can't. The way that you are working - it would always go back to the database - because you are using the filter methods. You would need to create a list from the items, then do the comparison in python - which probably will be slower (but not necessarily). Regards, Andréas Den ons
