Django get_or_create with icontains - django

Question

I'm getting an unexpected result using icontains in my get_or_create call.
Take the following example:
>>>team_name = "Bears"
>>>Team.objects.get(name__icontains=team_name) # returns DoesNotExist as expected
>>>team, created = Team.objects.get_or_create(name__icontains=team_name)
>>>print(created) # Prints True as expected
>>>print(team.name) # Prints an empty string!
Why does this create a team with a blank name rather than "Bears"? The reason I'm using get_or_create here is that if a subsequent user posts something like "BearS" I want to get the correct team, not create a duplicate team with incorrect capitalization.

Answer 1

I think here you should split the get() and create() functionalities instead of using get_or_create(), because the __icontains lookup works for get() only.
Try doing something like this:
>>> team_name = 'Bears'
>>> teams = Team.objects.filter(name__icontains=team_name)
# This will filter the teams with this name
>>> team = teams.first() if teams.exists() else Team.objects.create(name=team_name)
# Now your team is the first element of your previous query (it returns a QuerySet with single element) if it exists
# Otherwise, you create a new Team.

Another option besides wencakisa's answer is to include the defaults parameter in get_or_create, because Django strips lookups containing the __ separator. See answers to this question.
The code would be:
Team.objects.get_or_create(
name__icontains=team_name,
defaults = {
"name": team_name
}
)

The right way to do it is using Django's function get_or_create(). But instead of "icontains", you should use "iexact" (), unless you want an exact match, in wich case you should use just "exact":
Team.objects.get_or_create(
name__iexact=team_name,
defaults = {
"name": team_name
}
)
Outside "defaults" you should put your search terms. If the objects doesn't exist, you should write your creation terms inside 'defaults'
