Can somebody help me?

Answer 1

Your DATABASES-setting is incorrect, see docs for details.
What you need is:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'mydatabase',
'USER': 'mydatabaseuser',
'PASSWORD': 'mypassword',
'HOST': '127.0.0.1',
'PORT': '5432',
}
}
The configuration for the connection needs to be inside of 'default': {...}, you placed it directly inside of DATABASES.
