python - Field 'id' expected a number but got 'admin'. in django

Question

i created this to make searchbox to search models, when i replace body instead of author it works perfectly and fetches data accurately but when i use foreign key object string input is not working but when i type pk of user it fetches the username accurately but does not accept string for eg: when i type name of the post it gets but on author when i type name of the author it says following error and does not accept string but can accept pk and fetch author

pls edit this code such that when i type name of the author it gets the name and their post
