How does set_default_index_prefix('foo_') works?

[Boris-Sachet]

Hi, I'm not sure I understand how the method set_default_index_prefix('foo_') is supposed to work. Should it be called in the model? Before the connexion?

I tried to put it everywhere but nothing seems to work, the prefix used to store my class is always esorm.

Here's my very simple use case:

class Profile(ESModel)
    username: str = Field(frozen=True)
    profile_name: str = Field(frozen=True)
    config: list[dict] = Field(default_factory=list)

if __name__ == "__main__":
    set_default_index_prefix('foo_')
    asyncio.run(connect("http://localhost:9200"))
    set_default_index_prefix('foo_')
    profile = Profile(username="test_username", profile_name="test_profile_name",
                      config=[{"test": "foo", "columns": [{"name": "the column name"}]}])
    asyncio.run(profile.save())

The newly created index is name esorm_profile instead of foo_profile, am I missing something?

Hi, You should call it before you create the model. It is a global variable. And the model meta class uses it. So if you set it after the model declaration, the prefix is already set.

set_default_index_prefix('foo_')


class Profile(ESModel)
    username: str = Field(frozen=True)
    profile_name: str = Field(frozen=True)
    config: list[dict] = Field(default_factory=list)

if __name__ == "__main__":
    asyncio.run(connect("http://localhost:9200"))
    profile = Profile(username="test_username", profile_name="test_profile_name",
                      config=[{"test": "foo", "columns": [{"name": "the column name"}]}])
    asyncio.run(profile.save())

Thanks! I didn't think of that...
You might want to precise that in the doc just in case :)
