Get the instance of that object after the .save() to do an update

  • 772

I have saved an object with .save()and I would like to get the id to update it after saving it, do you know any way to make a query on the same generated instance of the object.

I have tried the following code but it does not update me.

dash.save()
Dashboard.objects.filter(pk=dash).update(userInstance=userInstance)
python

    I don't quite understand what you're trying to do. If you want to update userInstance(which I assume is a field of your model Dashboard) you just have to use the instance you have at hand:

    dash.userInstance = userInstance
dash.save()

  2. once you record you can manipulate the data directly.

    example:

    dash.save() #guardas la primera vez

print(dash.id)
dash.name = 'Nuevo nombre'
dash.campo = 'Nuevo valor'
dash.save() #realizas el update

  3. Hello, it's simple, nothing is needed, just access the id attribute:

    dash.save()
print(dash.id) # asi de simple

    Cheers
